Dr. Bea worked with the US Army Corps of Engineers, and Royal Dutch Shell around the world. His research and teaching have focused on risk assessment and management of engineered systems. He is co-founder of Center for Catastrophic Risk Management at UCB.TranscriptSpeaker 1: Spectrum's next. Speaker 2: Mm [inaudible]. Speaker 1: [00:00:30] Welcome to spectrum the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 3: Good afternoon and welcome to spectrum. My name is Chase Jakubowski and I'll be the host of today's show. Today we present part two of our two interviews with Robert B professor emeritus of civil and environmental engineering at UC Berkeley. [00:01:00] Dr B served as an engineer for the U S Army Corps of Engineers, Shell oil, shell development and Royal Dutch Shell. His work has taken them to more than 60 locations around the world. Has Engineering work, has focused on marine environments, is research and teaching, have focused on risk assessment and management of engineered systems. He is cofounder of the Center for catastrophic risk management at UC Berkeley in part two. Brett swift asks professor B about the California Delta balancing development and environmental conservation and shoreline retreat. [00:01:30] Is civil engineering misunderstood Speaker 4: or do people simply have a love hate relationship with the built environment? I think a mixture of civil engineering has been changing, so people's preconceived views in many cases are out of date and it's also low of, hey, when the built in art man bite you, it hurts and [00:02:00] hurt, encourages. Hey, there is a big reliance on it though at the same time as well. Yes. Airports, bridges, tunnels, water supply system, sewage supply, large ill NGS. That's our game. We're out of Egypt and Rome. That's where we got our start. And now the new term is infrastructure. Yes. To sort of put all that together into one idea. Yes. [00:02:30] Are there landscapes scale projects out there that people should be aware of and cognizant of? Yeah, that are underway or have recently completed? Yes. One we've been watching carefully is location than the other lunch and it's what's called the water works and the reason we zoom in closely is it's an excellent laboratory test bed for a comparable [00:03:00] problem we face here in California with aren't California Delta infrastructure systems. Speaker 4: Now the Lens, much more comeback, but it deals with an unforgiving test that's the North Sea. And so they've been learning actually over a period of 3000 years. How would it work in a constructive collaborative way with water? We face the same problem here at home. [00:03:30] Often the attention associated with civil engineering projects is due to the tension between environmental degradation and economic gain. Is it possible to have balance when you're doing something on this kind of scale? Answer is yes and it's a term bounce. Nature itself can be extremely destructive to itself. Watch an intense [00:04:00] storm attack, a sensitive reef area in the ocean. The tension and it can be constructive if it's properly managed, is we need to develop these systems, some of which need to make money and at the same time we need to ensure that what is being achieved there is not being degraded, destroyed by unintended consequences [00:04:30] to the environment. Speaker 4: One of the very good things that happened to civil engineering here at Berkeley is we changed our name. We're known as civil and environmental and that's to bring explicit this tension between built works, the natural works, and for God's sakes, remember we have a planet that we've got to live on for a long time. As engineers, we are still [00:05:00] learning how to deal with that tension and particularly when something's on a really large scale, best of intentions going forward, body of knowledge at the time you do the project, how do you know what the environmental impacts are going to be? Those unintended impacts reveal themselves. How do you walk these things back? How do you backtrack from having installed something on a landscape level? That clunky question. [00:05:30] That's one of the reasons for my fascination with the Netherlands, but the way I've worked there for a year, complements of previous employer [inaudible] is Royal Dutch Shell, so I was there learning all the dodge had confronted flooding from the North Sea and essentially the approach was built a big dam wall between you and at [00:06:00] water, you're on the dry site and it's on wet side. They promptly learned that was not good. The in fact heavily polluted areas that they were attempting to occupy and suddenly a new thing started to show in their thinking called give water room so that today they have actually sacrificed areas back to the open ocean [00:06:30] to get water. The room needs to do what it needs today and in the end the entire system has been improved. We've been trying to take some of those hard won lessons back to our California Delta Speaker 5: [inaudible].Speaker 6: You were [00:07:00] listening to spectrum on k a l x Berkeley. Brad swift is interviewing Bob Bobby, a civil and environmental engineer at UC Berkeley. In the next segment they talk about the California Delta Speaker 5: [inaudible].Speaker 7: We've talked about the delta a bit. Do you want to expand on the challenges of the Delta and [00:07:30] the downside? Speaker 4: Well, I'll start with the downside. One of the things I used to say in class when I was still teaching here is terror is a fine instructor. Okay. So the downside would be if we had what we call the ultimate catastrophe and it's foreseeable and in fact predictable [00:08:00] in our delta, we would be without an extremely important infrastructure system. For a period of more than five years. That includes fresh supply for small cities like Los Angeles and San Diego and small enterprises like the Central Valley Agricultural Enterprise. So the picture makes Katrina New Orleans look like a place [00:08:30] story. This is big time serious. You'd say hooky bomb. That's a pretty dismal picture. Why? And the answer is back to this risk crepe. The delta infrastructure systems started back in the gold rush days and we want to add some agricultural plans that we built, piles of dirt that I've called disrespectfully [inaudible]. And then we put in transportation [00:09:00] roadways, power supply, electrical power, and then we come up with a bright idea of transporting water from the north side of the delta to the South side of the Gel so we can export orders. Speaker 4: Southern California. Those people need water too. Well, it's all defend it by those same piles or hurt built back in the 1850s it's got art, gas storage under some of those islands and our telecommunications goes through there. [00:09:30] Our railroads go through air, so if you lose critical parts, those piles there, you got big problems. We can foresee it, we can in fact analyze, predict it. We've in fact quantified the risk. They are clearly unacceptable. We've talked to the people who have political insight and power. They are interested to the point of understanding [00:10:00] it and then they turn and ask, well, how do you solve the problem? Well, at this point we say we don't know yet, but we do know it's gonna take a long time to solve perhaps much like the Netherlands, 50 a hundred years. And you can see a Lee blank because there's a two to four year time window. What's this? 50 to a hundred years. Oh, can you tell me about tomorrow's problem? And tomorrow solutions [00:10:30] answer, no, this one's not that. So we've run into her stone wall. Speaker 7: So does it then become something that gets tacked on to all the other things that they want to do with the water? Because there's always a new peripheral canal being proposed. Right? Right. And the north south issue on water's not going away. So for some 50 years solution to happen in California politics, you'd have to have a pretty serious [00:11:00] consensus north and south to the shared interests there. Correct. And there's no dialogue about that really? No. Within the state, no. How about within the civil engineering community? Within the state? No. So everyone wants to ignore the obvious threat to the, so the California economy because basically you're talking about have you applied a cost to the a catastrophic event of the Delta failing? Speaker 4: Oh yeah, we thought that. Or Action Katrina, who Orleans [00:11:30] ultimately has caused the United States in excess of a hundred bill young as ours. Paul that by five or 10 because just the time extent. The population influence though we're talking about hundreds of billions, trillions of dollars. So the economic consequences of doing nothing or horrible and then you'd say, [00:12:00] well, is it possible to fix it? Answer is yes. Well, do you know exactly how? No, we don't. That's going to take time to work through. It also takes key word. You mentioned collaboration. Different interests are involved and we need to learn how to constructively and knowledgeably liberate the signings to say, here's a solution that makes sense to the environmental conscience [00:12:30] in the environment. Here's a sense or a solution makes sense to the social commercial, industrial complex. Hey, we might have a solution here. Let's start experimenting it. We don't have the basis for that lot and consequently it slips back into our busy backgrounds. Much like the San Pedro LPG tanks that are still sitting air. It's in the background and the clock is ticking Speaker 7: and the Dutch model [00:13:00] doesn't help them see how it could evolve. Speaker 4: It doesn't seem to, they sort of have distanced the experience from the Netherlands and saying, well, we could never come to an agreement like that. Of course, as soon as you say that, that's the death coming to an agreement like that. Speaker 7: Well maybe they don't see the impending danger as existential as the Dutch do. Speaker 4: I think that's very true. The Dutch can just walk [00:13:30] outside of their homes. Many of them walk up one of those levees and on the other side they see what's happening. The North Sea is big and mean and ever present and they've got one common enemy, so to speak, and that set ocean and they got to stop the flooding, but yet they can't damage the environment. So they've had to come to grips one with themselves. One more the environment and the long term view. We could do it. We haven't. Speaker 8: Okay. Speaker 6: [00:14:00] Spectrum is a public affairs show on k a l Ex Brooklyn. Brett swift is with our guests, Professor Robert B of UC Berkeley. In the next segment they talked about Shortline retreat and regulation of oil and gas extraction Speaker 5: [inaudible]Speaker 7: [00:14:30] with the sea level rise and with storms becoming more volatile and surges from the oceans becoming real factors on shorelines. How should communities and nations approach the idea retreating from the ocean? Speaker 4: Well, again, thankful to our brothers and sisters and Europe. [00:15:00] They're several decades ahead of us in asking and answering exactly that question. They've developed three strategies. They look at existing locations. They then examine each of the three strategies to see which makes longterm sense. The first strategy is fight. A good example would be United Kingdom, the tims flood [00:15:30] barrier. Yeah, you might like to move London, but to not gonna move it very quick easily. And so the answer comes back we need to defend, but you only defend what you can defend, which means you don't try and defend the entire coast of England. You defend small parts of it that can be adequately defended. That's the fight strategy. The next one is flight. I call it get [00:16:00] out of dodge city. And so they say we need to stay age, a strategic withdrawal so that we withdrawal slowly surrendering back to the environment which needs to be surrendered back to the environment and eventually we're gone. The next one is freeze. What the mean is we'll occupy it until it's destroyed and then we're gone. As we looked at the coast, New York, [00:16:30] New Jersey after Sandy, I wish we had done some of that thinking. I hope we do some of that thinking for our California Delta. Speaker 7: I was thinking about civil engineering as it's applied in different parts of the world where a nation state is in a different stage of development. And how do you see civil engineering interacting in those environments differently and taking in risk management and how it's applied? Speaker 4: Well, I guess each society [00:17:00] has to go through its own learning experiences. You can always look at other society and say, oh they weren't very smart or they certainly could have done it this way, rather they did it. So we all into the after the game quarterbacking sort of Mo seems like each of these countries societies has to go through its own learning experience. [00:17:30] As I said earlier, those risk assessment and management businesses one damn thing after another and this learning transfer of insight forward seems to be as frustrating and difficult. Speaker 7: So offshore. Let's Speaker 4: talk about the challenges inherent in that. What do you think about the debate about the risk? How should that debate be framed? [00:18:00] The risks are higher, which means that likelihoods failure that you engineer into the system, it would be much lower, have to have backups in defense and depth and people who actually know they're doing the question is, will we in fact do it before we have a disaster? Don't tell me you think it's safe. Show me and demonstrate to me is that demand has not happened here in the u s yet. [00:18:30] I'm very concerned. For us, I think the government changed some of the permitting process. Is that window dressing? What does it have some real impact on how people behave in the field? It depends on geographically where you're ant Alaska has been very demanding at the Alaskan state level relative to oil and gas operations and when you see a signature [00:19:00] go home or permit, you can pretty well bet that there's sufficient documentation demonstration to justify that signature. Speaker 4: Other parts of the u s are less diligent and so it depends geographically where you're at and what you're dealing. Well, it's not actually reasonable to expect to be able to appropriately regulate, govern and industry [00:19:30] as powerful as the oil and gas industry was spotting governance. Governance needs to be consistent and when the signature goes on to a form that says, yes, I have the ability to immediately abate the source of a blow out. You have the ability the fire engine is built, it's in this station with trained people. Let's ring the bell and see if that fire engine can run. That hasn't happened yet. I [00:20:00] remain personally very concerned for these Oltra high risk operations we're considering in the United States wars. Does the same spottiness occur with fracking in terms of the application of best practices, everything up and able to learn is, yes. Speaker 4: By the way, franking has been underway for many decades. Industry actually hit this kind of work underway intensely in the 1970s [00:20:30] it says spottiness we're back to. That becomes crucial if the regulation governance and that's both internal governance within the industry and external governance on behalf of the public. If it is demanding, insightful and capable, we're okay, but if it's not, we're not. Okay. The systems that you have to have an interesting ability to slip to the lowest common denominator. [00:21:00] By this point, my career, I've worked in 73 different countries. I've lived in 11 different countries, I've seen a company I have a lot of respect for at Shell, operate internationally, some areas, gold standard, Norwegian sector, North Sea, and then I go to work with them in Angola. It's not a very good standard at all and [00:21:30] that's because the regulatory environment with local and national Franco relative to oil and gas is very poor, so the system seems to adopt the lowest sort of common denominator. Can. Strong industry requires strong governance to this man at the end of that experience. Bobby, thanks very much for coming on spectrum. Very much pleasure for that integration.

Wednesday, December 12th citrus at UC Berkeley is hosting a talk by executive director of the Institute of the future Marina Corbis. Marina Corpus's research focuses on how social production is changing the face of major industries. In this talk, she will discuss her research along with her insight to our society's future. The talk will take place Wednesday, December 11th [00:25:30] from 12:00 PM to 1:00 PM is the target Dye Hall Beneteau Auditorium on the UC Berkeley campus and now Brad swift joints. Me for the news. UC Berkeley News Center reports the funding of a new institute to help scholars harness big data, the Berkeley Institute for data science to be housed in the campuses. Central Library building is made possible by grants from the Gordon and Betty Moore Foundation and the Sloan Foundation, which together pledged 37.8 [00:26:00] million over five years to three universities, UC Berkeley, the University of Washington and New York University to foster collaboration in the area of data science. Speaker 7: The goal is to accelerate the pace of scientific discovery with implications for our understanding of the universe, climate and biodiversity research, seismology, neuroscience, human behavior, and many other areas. Saul Perlmutter, UC Berkeley professor of physics [00:26:30] and Nobel laureate will be the director of the campuses. New Institute. David Culler, chair of UC Berkeley is the Department of Electrical Engineering and computer science and one of the co-principal investigators. The data science grant said computing is not just a tool. It has become an integral part of the scientific process. Josh Greenberg, who directs the Sloan Foundation's digital information technology program said this joint project will work to create examples [00:27:00] at the three universities that demonstrate how an institution wide commitment to data scientists can deliver dramatic gains in scientific productivity. Speaker 3: NASA's newest Mars bound mission maven blasted off while faculty, students and staff assembled at the space sciences laboratory to watch their handiwork head to the red planet. More than half of the instruments of board the spacecraft were built at UC Berkeley. After a 10 month trip, it will settle into Mars orbit in September, 2014 where it will study the remains [00:27:30] of the Martian atmosphere. Maven was designed to find out why Mars lost its atmosphere and water. Scientists believe that Mars once had an atmosphere, oceans and rivers, very similar to Earth. From its Martian orbit. The spacecraft will collect evidence to support or refute the reigning theory that the loss of its magnetic field allowed solar, wind, and solar storms to scour the atmosphere way of operating any water not frozen under the surface. The answer to this question will give planetary scientists a hint of [00:28:00] what the future may bring for other planets, including earth. Speaker 8: Okay.

In critical spawning and overwintering habitat for salmonids Hwan studies the effects of temporal stream fragmentation across three organizational levels of ecology: population, community, and ecosystem levels.TranscriptSpeaker 1: Spectrum's next Speaker 2: [inaudible].Speaker 1: [00:01:00] Welcome to spectrum the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 3: Hi, my name is Brad Swift. I'm the host of today's show. Our interview is with Jason won a third year phd student in the Carlson lab, which is [00:01:30] part of the environmental science policy and Management Department of the College of natural resources. Professor Stephanie Carlson directs the lab and she is a fish ecologist. Jason is researching the effects of summertimes stream drying on fish ecology in the John West fork, a creek in Marin county. The John West fork is the spawning grounds for two varieties of salmon the summer of 2011 Woolmark the third year of his research on this stream. [00:02:00] His research will continue for two and possibly three more years. This interview is prerecorded and edited. Speaker 4: Jason, welcome to spectrum. Thanks for coming in. Thank you. Wanted to ask if you could, uh, give us a brief overview of your research and add in there how it's being funded. My research is looking at the effects of low summer flow on juvenile steelhead, on the insect communities out in the stream and [00:02:30] on certain ecosystem processes such as Algal production and leaf decomposition. And it's currently being funded by, mostly by my, by my guiding professor, Stephanie Carlson. And I also have some funding from our department and the division within our department. All right. We get out a sperm wildlife grant, which helps fund the research. And also I'm currently on an NSF graduate research fellowship. Described the, the general [00:03:00] area of the site that you chose. Sort of put it in context of where it is. So my study say, uh, the John West work is in point Reyes national seashore, which is about an hour north of Berkeley in a national park in and surrounded by some state parks. Speaker 4: Also. Can you explain the watershed and the area that you're working, how it all interrelates to the watershed? So I'm, I'm working in the Lagunitas watershed. I'm working [00:03:30] in a creek that is a tributary of a tributary of a creek to the lock Anitas to log in neatest creek and log Anitas creek flows into Tomas Bay in point rays. The creek that I'm working in is a little different in that there are only two species of fish up there. Both our salt Monets, there are still head and coho salmon. This is because it's not that the creek went dry, completely dry one year and there's, there [00:04:00] was a culvert that was put in place and other fish species weren't able to recolonize the creek, but someone had adults can jump over the barrier. And so they were able to recolonize the creek and they're actually jumping through the culvert. Speaker 4: Yeah. And through this culvert and swimming up swimming into the two John West work. And what's the drop on the culvert like from, from the the bottom lip to the dead of the bid. Lower part [00:04:30] of the creek. It's about four feet. Four feet drop-off. Yeah. So that's quite a leap for the salmon. Yeah. And so with this study, what is it that you're trying to learn? That is not already known. So I'm basically trying to look at the effects of low flow and my study is really looking at what the affects are at a really fine scale. So I'm tracking, uh, juvenile steel head growth, movement and survival and I'm tracking them on a weekly basis. So [00:05:00] it's pretty fine scale monitoring, which is something that hasn't really been been carried out before. And the low-flow period is when, uh, the low, the low flow start after the last records. Speaker 4: And as the, as a temperature gets warmer, the stream starts to dry and it pretty much lasts throughout the summer until the first rains of the following year. Are you collaborating with other people on your project? Not directly with my lab mates on [00:05:30] my project. Sometimes they might come out and help me, but for the most part I've been working alone with the help of some undergraduates. There are certain side projects that we collaborate on. Um, there's also a person who is working with me from, uh, from a different department. He's not really working on my project, but, uh, something that's related to my project out on my field site. It mean it helps both of you? Yeah, definitely. And is that going to have some bearing is his, his [00:06:00] work or her work and I have some impact on your results. It definitely is connected. It is connected to, I'm more at the temperature and looking at how stratification and pull temperature stratification in pools might affect fish behavior. Speaker 4: So where, where they kind of hang out in the pool. So that's something that could definitely help us fold into your report. Yeah, exactly. So in doing your research [00:06:30] and working in the field as opposed to, uh, if you're working in the field and the lab, how much time do you spend in the field and in the lab? Um, when I'm out during the summer, uh, during my field season, it's a pretty big chunk of it. About 80 to 85% is probably spent in the field and the remainder is spent in the lab. Um, but once the summer is over and on, the field season is over. Most of the time is spent in the lab, um, [00:07:00] crunching data, processing samples and stuff like that. Speaker 5: [inaudible]Speaker 2: you're listening to spectrum on KALX Berkeley. Today we're talking with Jason Juan about his research into summertime streaming drying its effect on Fish CollagenSpeaker 5: [00:07:30] [inaudible]. Speaker 4: And so was there fish breeding going on in this part of the Stream? I would assume that that's the reason they're up there. Yeah. So one of the adults jump up into the stream. They breed typically during the winter when the rains, they come back with the rains [00:08:00] and they breed and the eggs hatch and spring. And then I kind of track the juveniles once they get to a large enough size to be able to monitor to them. So as you start to go up in the early spring, you're seeing lots of of small fish. Yeah. And it's so the fish that have spawned, have they left then or are do some stay? Yeah, but most of them have left. They're too large to stay in some of these pools. So most of them leave and with the Coho that or [00:08:30] they die right after they breed because they just breed once and they die. Speaker 4: But with the, with the steelhead, they're able to breed multiple times. And Are you tracking it all that mortality of the coho that are coming up and breeding? No, but the park service is definitely keeping track of adults, adult spawners they go up every winter and quantify the amount of a salmon reds, which are the nests that someone is build. And they also try to [00:09:00] keep track of how many fish, adult fish that they see. Talk about the insects in the fish in the same context of the frequency. So with, with the insects, um, it's, it's a pretty disturbing method to go and collect them. So we try not to collect them too frequently. We recollect them once at the beginning of the summer and again at the end of the summer. So we don't want to disturb the habitat too much that we have to kind of dig in [00:09:30] to the stream and it just disrupts, disrupts things a lot. Speaker 4: So we try to keep the frequency down and with the fish, um, we go out again, it's similar to to the insects that's we have to go and shock them and which as you can imagine, um, is quite stressful to the fish. So we shock them once in the beginning, beginning of the summer and we place pit tags into them, um, which allows us to monitor them across [00:10:00] the summer without having to actually handle them. Also, while we, um, capture them during the first event, we weigh them and measure them. And then during the late season capture event, we weigh them and measure them again and we're able to identify which the fish that were tagged, we were able to determine their growth rates and their survival. In addition, we can monitor them using the pet tags. We have a, a [00:10:30] handheld antenna that we take out and we just place it over the stream and we're able to find out where they're located or, and also if they're other still alive. Speaker 4: So that happens pretty much once a week. So the pet tag is like a radio. Gotcha. Yeah, it's an audio id, tariff id similar to what is found in a for pets, the microchips that they use for pets. And then you can also measure the mortality with that as well I guess if, yeah, so we go [00:11:00] out and we try to track their movement and also if we find a pit tag, we just kind of disturb the area around, uh, around the tag lightly. And if, if the tag isn't moving, then we kind of can surmise that there has been a mortality event that that occurred. Do you remove the fish or the die or now it's pretty hard to find them because we don't track them every day. So, so things happen [00:11:30] within the week and sometimes we kind of look around for the tag but it's pretty hard to find the tag. Speaker 4: But if we do come across any fish we do, we do take you back to the lab. Any dead Fisher and they are often tagged or have they not? Some of them are just untagged. We try to tag as many fish that we can capture at that are a certain size. They to be a certain size and size for them. So we do try to capture and tag every fish that is of [00:12:00] a certain size, but whether we do within that period of time that you can do the, that you're doing the tagging because you try to limit that. Yeah. How long is that period? What do you do? I've tried to do it all in a week. Three to four days. The tagging, the taking takes about three to four days. The caption and taking. And what's that like in terms of a process? Is it, is it you and a bunch of people doing it together? Speaker 4: Yeah. Take a little group out. Yeah, we actually took a group out, um, and we actually stayed out there for the three, three or four days. We wanted to get an early start [00:12:30] in the day and it takes about an hour to get, get out there each day. So we just decided to stay out there and it's actually quite fun. Um, most, most people really everybody volunteers to do to do like fish capturing. They're like, oh yeah, I want to do that. It's something that the interns really enjoyed. So is that time that you're in the creek, are you actually standing in the creek? So I, yeah, I actually get into the creek and I have a, an electrical Fisher and I move through the creek, [00:13:00] shocking the fish and there are a couple of them matters beside me on the scoop up any fish that had been shocked and we placed them into a bucket and then from there we kind of weigh them and measure them after, after all the fish have been captured for a certain pool. So you do this pool by Paul? Yeah, exactly. Speaker 5: You [00:13:30] are listening to spectrum on KLX Berkeley. We're talking with Jason y about his researching the summertime scream drying and its effect. Speaker 4: So Jason, how did you get interested in science when you were in high school, say or college? [00:14:00] I've always kind of really been interested in science as a kid. I really enjoyed reading science textbooks and it was as one of my favorite subjects and I just decided to stick with it. And I, I majored as a, as a biology student. And what about it appealed to you when you were young? It was like, it was the investigative process, [00:14:30] I guess that that appealed to me. It was just something that you can go out and observe and I really like that, that you can, you can actually just go out and see how nature works. And I was really fascinated by that. So biology was sort of the entree and then as you went through high school, College, yeah, I majored in biology and I really enjoyed my ecology class, just getting up out [00:15:00] there and I wasn't too keen on the molecular side of biology, but the ecological part aspect of it was really fun to get out there and observe things. And, and so it was it field work then that led you to streams? Yeah, I actually worked as a, as an undergraduate. I worked with a professor of mine and he would take me out into streams in southern California and it was quite a great experience for me. And what sort of work and studies research [00:15:30] was he doing? He was, he was doing, uh, population, uh, studies of endangered and threatened fish in southern California. Speaker 4: So when you're in the lab, what sort of data are you gathering? So for instance, with the leaf litter bags and the Algo production, um, when we come back from the field we have to process those samples. So we deploy tiles and we have to scrape off the LG from the tiles. And then we [00:16:00] have to run an analysis to quantify chlorophyll production. With the leaflet or bags that we set out, we bring them back and we, we way leaves in them and quantify how much leaf litter mass has been lost across time. What is it about the algae that you want to know in the river? With both the algae and the leaf litter, we want to see how the stream drying effects say Algal PR productivity or leaf litter decomposition. So we want [00:16:30] to see how much, how much Algo productivity there is in the early part of the summer when or when the stream is still pretty connected. Speaker 4: And then again, we want to track that change over time to see how productivity changes as the string gets dry and dry and with the leaf decomposition, same thing, seeing it over the, over the time, yeah. We want to see how decomposition rates change as the stream gets dryer and with that we're finding that decomposition rates slowed down quite a bit. [00:17:00] As the stream dries, there's less microbial activity, less insect funner to shut up the leaves. Are there other key data points that you're collecting out of the stream? Yes. I'm trying to measure the volume of water in the creek. Mostly the volume of water in between the pools of the fast flowing portions called riffles. I tried to measure how much water is in these portions and I go out pretty much every week and measure the dimensions [00:17:30] of the riffles and I'm able to get volume on every week and I'm able to quantify how this volume gets smaller and smaller every week. Eventually these, these pools are isolated and there's no more flow exactly. Between pools. Yeah. The, the riffles just most of them completely dry up by the end of summer. Speaker 3: And so the fish are then isolated in these, yeah, they're isolated. Speaker 4: The there aren't able to move among the different pools Speaker 3: at this point. Is it too soon in your study to, to [00:18:00] reflect on what you might conclude? Well, I'm, Speaker 4: I'm already seeing some pretty drastic inter-annual variation and precipitation in the area. So as I mentioned earlier, 2009 was a very dry and that was your first year? Yeah, 2009 was a very dry year, so I noticed that there was quite a bit of a mortality for the fishes. Uh, this past year, 2010 and during that summer was a lot wetter. There was a lot more habitat for the fish. A survival was a lot higher. So [00:18:30] Marty seen, uh, some significant results in terms of inter annual variation and how more extreme temperatures and extreme dry might influence the fish population. Speaker 3: Is there any part of water quality that you're measuring? Speaker 4: Temperature and a dissolved oxygen levels? Not In terms of pollution really, but a temperature and dissolved oxygen are are really key for [00:19:00] some almond species in particular, they require cool temperatures that are pretty well oxygenated. Speaker 3: The information that you're getting from your study will have an impact on other streams and creek management potentially. Yeah, that's, that's my hope Speaker 4: is that especially in certain areas where water withdrawals occur and there needs to be a certain amount of a water, hopefully our findings can maybe influence these areas where water withdrawals occur in the [00:19:30] stream comes even more dry than they typically should naturally. Speaker 3: Jason, thanks very much for coming in and talking about your research. Yes. Speaker 6: Oh, Speaker 7: [inaudible].Speaker 3: A regular feature of spectrum is dimension.

This item from the inside science news service scientists battle the dramatic declines of honeybee colonies with targeted breeding. There are a handful of pests and diseases that individually and in combination are causing unprecedented mortality in [00:23:30] honeybee colonies in Europe and North America. Serious efforts are being made to find solutions that can eradicate the pests and diseases. While the search for a solution continues. Researchers in Canada and the United States are attempting to bees that are resistant to Mites and viruses that attack bee colonies. The breeding process exposes the Queens to high levels of what is termed disease pressure. According to Rob Curie, professor of entomology [00:24:00] at the University of Manitoba. The survivors are then bred next season and so on. Seven generations have been bred so far. We are looking for bees that are resistant to mites and with a greater tolerance to viruses because they appear to be the two main factors behind colony loss. Speaker 3: QRI said and added breeding attribute pursued by the Canadian breeders is the ability to withstand the brutal North American winters. Curious said [00:24:30] that normally only 46% of the species known as European honeybees survive the Canadian winter, but the newest generations have a 75% survival rate. The total losses from managed honeybee colonies in the United States were 30% from all causes for the 2010 2011 winter according to the annual survey conducted by the US Department of Agriculture and the apiary inspectors of America. [00:25:00] This is roughly similar to the losses reported in similar surveys done in the four previous years. This story from Metta page today, lab grown trickier implanted in patient June 9th, 2011 at the Karolinska University Hospital in hunting, Stockholm, Sweden. Dr Paolo Macchiarini implanted the first ever bio artificial trachea grown on a synthetic [00:25:30] substrate using the patient's own stem cells. The patient was a 36 year old cancer patient for this procedure. Dr Macchiarini and his colleagues collected stem cells from the patient who had late stage tracheal cancer since no suitable donor windpipe was available. The researchers used a nano composite tracheal scaffold designed and built by Alexander Se Follian Phd of the University College London. [00:26:00] They seated the polymer model with auto Lucas stem cells. These are blood forming stem cells and grew them for two days in a bioreactor. Dr Mk Jadine says there's no room for rejection because of the cells are the patient's own. Thus, there is no need for him to be on immuno suppressive drugs.
