Podcasts about Quagga

Le 25 mai, c'est la journée internationale de l'Afrique. BSG rediffuse à cette occasion cet épisode de NOMEN, l'un des 4 petits frères de Baleine sous Gravillon. Il existe 3 espèces de zèbres, que vous saurez distinguer à la fin de l'épisode :le Zèbre des plaines (de Burchell) : 25 à 30 rayures, le plus abondant, le moins rayé.le Zèbre des montagnes (vrai, daw) : 43 rayures, le mâle a une grosse pomme d'Adam (sillon gulaire) in the middle ;), en voie d'extinction.le Zèbre de Grévy : 80 rayures, en voie d'extinction, plus proche de l'âne.Tous les trois appartiennent au genre Equus. Le Zèbre des plaines et le Zèbre des montagnes appartiennent au sous-genre Hippotigris. Ils ressemblent au cheval.Mais le Zèbre de Grévy est la seule espèce du sous-genre Dolichohippus. Ce dernier ressemble davantage à un âne, auquel les zèbres sont étroitement apparentés génétiquement.  Le Zèbre de Grévy et le Zèbre des montagnes sont en danger d'extinction. Les zèbres des plaines sont beaucoup plus abondants, mais une sous-espèce, le Quagga, rayé sur une seule moitié du corps, a disparu à la fin du 19e siècle. En 2016, on dénombrait, dans toute l'Afrique, moins de 800 000 zèbres. Une légende africaine demande si le Zèbre est blanc à rayures noires ou noir à rayures blanches. Cette question a généré de nombreuses légendes ou réponses fantaisistes, mais des explications plus scientifiques existent. Les premières populations de zèbres étaient de couleur gris-ardoise. Les zèbres étaient originellement des animaux pigmentés de noir. Les raies blanches se forment par inhibition de la production de mélanine. Les fœtus sont en effet tout noirs. Les rayures faciliteraient le camouflage vis-à-vis de la mouche tsé-tsé ou des grands prédateurs. De nombreuses théories sont proposées mais aucune n'est validée. Les autres hypothèses sur la fonction des zébrures concernent :Le camouflage (casse la silhouette)L'évasion face aux prédateurs (effet stromboscopique ou "dazzle"). La thermorégulation (l'aternance noir et blanc crée des microtubulences qui rafraîchissent le Zèbre sous le cagnard africainLes interactions sociales (se reconnaître avec un système de code-barres).Le petit du Zèbre s'appelle le zébreau et la femelle du zèbre s'appelle la zébrelle. On rencontre aussi le terme zébresse ou zébrette. Le zèbre hennit comme le cheval, mais le Zèbre de Grévy brait comme l'âne, on dit aussi qu'il jappe.Quelques proverbes sublimes pour finir : « La pluie mouille le zèbre mais n'efface pas ses rayures » (massaï, Kenya)« Un homme sans tradition est comme un zèbre sans rayure » (Afrique)« L'ombre du zèbre n'a pas de rayures » (René Char, poète français)_______

SNWA researchers have been at the forefront of emerging water issues for the past 25 years, and their discoveries have helped protect Southern Nevada's drinking water supply. SNWA scientists have helped stop quagga mussel infestations from blocking water intake pipes and helped implement ozonation to the water treatment process. Eric Wert, Water Quality Research & Development Manager, talks about the emerging issues the lab currently is tracking and what might be the next generation of water treatment on this episode of the Water Smarts Podcast. Hosts: Bronson Mack and Crystal Zuelkehttps://www.snwa.com/ https://www.snwa.com/

Hey liebe Scrabble Fans! Anfang Mai findet die deutsche Scrabblemeisterschaft in Minden statt und wir vom tierisch!-Podcast verhelfen euch zu einem triumphalen Gewinn. Hier gibt es die Namen von Tierarten, die euch ganz weit nach vorn bringen. Quastenflosser auf den dreifachen Wortwert!!! Als Oase in der Servicewüste Deutschland, liefern wir neben tollen Wörtern sogar deren Buchstabenzahl! Letzteres zugegebenerweise auch, weil wir uns da erstmal falsch vorbereitet hatten: Wir haben nur die längsten crazy Artnamen wie zum Beispiel Gleichzahnohrenspitzmausmaulwurf oder auch Kaiserschnurrbarttamarin herausgesucht. Spannende Tiere, ihre Namen passen aber – irgendwie auch logisch – gar nicht auf das Scrabblebrett! Also haben wir zurück gerudert zu Yucatanspecht, Quagga und Quetzal. Übrigens auch tolle Wörter für Stadt, Land, Fluss. Nun wünschen wir unseren Scrabble Freunden in Minden viel Erfolg! Wenn ihr einen tollen Tiernamen gelegt habt, schickt gerne ein Foto an unseren Insta-Account von Weltwach!

Threats from the invasive Quagga mussel species are growing in deeper parts of the Great Lakes, just as zebra mussels have altered ecosystems in shallower water closer to shore. Quagga mussels compete for food with a number of young fish species, putting commercial and recreational fishing at risk, and also threaten historic wrecks. A look at how widespread the problem is, and efforts to control the invasive species, with the team behind documentary All Too Clear. See omnystudio.com/listener for privacy information.

The Idaho State Department of Agriculture returned to Twin Falls this October to continue treating the Snake River after detecting quagga mussels last year. Associate producer Logan Finney speaks with ISDA Director Chanel Tewalt about the eradication campaign, Idaho's multi-agency approach to managing quagga mussels, and impacts on the rest of the river.

Ende Sommer ist die schädliche Quagga-Muschel erstmals auch im Zürichsee entdeckt worden. Ab kommendem Jahr gelten deshalb auch strengere Regeln für Bootsbesitzerinnen und Besitzer. Sie dürfen ihre Schiffe nicht mehr vom einen ins andere Gewässer zügeln. Für Wassersportvereine ist das ein Problem.

In vielen Schweizer Seen verbreiten sie sich rasend schnell: die Quagga-Muschel. Diese entzieht den Seen Nährstoffe, die dann anderen Tieren fehlen, und sie befällt auch offene Wasserleitungen und Fischernetze. Im grössten Aargauer See, dem Hallwilersee, gibt es bislang noch keinen Nachweis. Weiter in der Sendung: * «Die Schweiz im Wandel»: Die erste Juragewässer-Korrektur hat die Armut im Berner Seeland erfolgreich bekämpft, aber auch neue Probleme geschaffen.

Bruce Johnson joined in on the show this week to highlight the addition of 2 new "Dip Tanks" in Utah to help prevent the spread of Quagga and other invasive species!

Die eingewanderte Quagga-Muschel verstopft massenhaft Rohre der Wasserversorger am Bodensee. Außerdem bedroht sie auch das Ökosystem. Was tun?

You may have heard that various kinds of invasive plants and animals create problems for the species that are native to an area. In the case of the quagga mussel, which only grows to the size of a thumbnail, its effects extend beyond the natural ecology and into the built environment. Not only can it take food away from juvenile salmon and other fish, but the mussels can clog all sorts of water systems, from municipal water to irrigation and hydropower. The quagga and the related zebra mussel came from Eastern Europe to the Great Lakes in the 1980s. In the last dozen years or so, quagga been found in California, Nevada and Utah. They also appeared in Idaho last year along the Snake River. Rick Boatner, the invasive species coordinator at the Oregon Department of Fish and Wildlife, says inspections and monitoring could keep the quagga out of the Columbia River Basin, but probably not for more than a few years. He says once they get in, quagga mussels will forever change how we use water in Oregon. He joins to tell us more about what’s needed to slow their spread and to highlight a few of the other invasive species on the agency’s radar.  

Tim is joined by Lt. Bruce Johnson from the Division of Wildlife Resources to discuss the number of invasive quagga mussels that affected Utah’s lake and boats this year.

Join Dr. Leif Tapanila and Peter Pruett for this episode of The Nature of Idaho, where our hosts sit down with Lloyd Knight from Idaho State Department of Agriculture to talk about invasive quagga mussels in the Snake River system.

Nature lovers need to be concerned about invasive aquatic species, especially the devastating potential of quagga mussels and their close relatives zebra mussels.

Of all the things we have imported from Europe, the Quagga Mussel is an accidental stowaway that threatens all U.S. waters. They can clog city water-intake structures, agriculture pipes, and create havoc on docks, buoys, boat hulls, and beaches. An estimated $500 million a year is spent managing them in the Great Lakes alone. Bruce Johnson, Lieutenant AIS Field Operations Utah Department of Natural Resources Division of Wildlife, shares in behind-the-scenes work to control these aquatic pests.

Idaho State Department of Agriculture's has an all-out effort to stop quagga mussels from gaining a foothold in Idaho waterways.

The Idaho State Department of Agriculture announced last week the presence of invasive quagga mussel larvae in the Snake River near Twin Falls. Director Chanel Tewalt joins Logan Finney to discuss what this means for Idaho and the state's response plan. Find more information at http://www.idaho.gov/quagga

Von WDR 5.

Am 12. August 1883 ist das letzte bekannte Quagga, eine Unterart des Steppenzebras, in einem Zoo in Amsterdam gestorben. Heute gibt es Versuche, die Quaggas wieder zurückzubringen. 

Die steigenden Durchschnittstemperaturen aufgrund des Klimawandels führen dazu, dass sich bei uns inzwischen Tierarten wohlfühlen, die hier definitiv nicht hingehören. Zum Beispiel die giftige Nosferatu-Spinne, die sich im Moment vor allem in Rheinland-Pfalz bemerkbar macht. Oder die Quagga-Muschel im Bodensee, die zwar nicht giftig ist, aber die Wasserleitungen verstopft und mit ihren scharfen Kanten Verletzungen bei Badegästen verursacht. Tiere und Pflanzen, die man vorher hier nicht als heimisch kannte, nennen Biologen „invasive Arten“. Welche Auswirkungen die auf unser Ökosystem haben, und was man gegen invasive Arten tun kann, darüber hat SWR Aktuell-Moderator Stefan Eich mit SWR-Umweltredakteurin Sabine Schütze gesprochen.

Die Quagga-Muschel droht sich im Kanton Bern auszubreiten. Es besteht die Gefahr, dass die gebietsfremde Muschelart in den Thuner- und Brienzersee verschleppt wird. Der Kanton hat deshalb nach 2020 eine zweite Sensibilisierungskampagne gestartet. Weiter in der Sendung: * Zu Besuch bei Jean-Pierre Grandjean, dem Fährimann vom Greyerzersee. * Sinnieren mit Regula Trachsel, über Brücken und ihre Funktionen im Leben der Menschen.

Seeland: Die Gemüseproduzenten müssen wegen der Trockenheit mehr künstlich bewässern; Biel: Das Schachfestival war ein Erfolg, die Sparmassnahmen der Stadt Biel drücken aber auf die Stimmung

Die invasive Quagga-Muschel breitet sich schier unaufhaltsam aus – und bedroht damit das Ökosystem der Schweizer Gewässer. In den Juraseen wurde die Muschel schon gefunden, im Thuner- und im Brienzersee noch nicht. Bedroht sind auch die Saane-Seen. Weiter in der Sendung: * Die Freiburger Staatsanwaltschaft eröffnet eine Untersuchung gegen Georges Godel. * ABB-Schweiz-Chef ersetzt im Herbst BKW-Chefin Suzanne Thoma. * Spannungserhöhung Bickigen-Chippis verzögert sich um mindestens zwei Jahre. * Die Steinfliege bremst Oberwalliser Wasserkonzession aus. * Gelson Fernandes verlässt den FC Sion in Richtung Fifa.

El quagga era una subespecie de cebra que fue cazada hasta su extinción a finales del siglo XIX por los colonos europeos. En la década de los 80's se lanzo El Proyecto Quagga para tratar de rescatar esta especie de la extinción. Lo sorprendente aquí, es que parece haber funcionado.

Quagga

No, the episode name isn't a typo. Rather, it's the name of a subspecies of zebra we're going to be discussing today. Along the way, we will explore clines, the purpose of zebra stripes and an attempt to breed back the quagga from its zebra cousins. Why don't we hear more about it? Well, because it no longer exists... Sources for this episode: 1) Bryden, H. A.

The Agriculture and Horticulture Development Board, which provides marketing and technical support to farmers, has published a new five year strategy. The AHDB is paid for through a compulsory levy on all farmers, with some paying thousands of pounds a year. The new strategy includes providing more tailored services to individual sectors, better communication and variable levy rates. The move comes after criticism from some growers, who believe the AHDB does not serve their needs, and want to stop paying. We hear from AHDB Chair, Nicolas Saphir, and one of the farmers who started a petition over the levy. The quagga mussel is a tiny shellfish, native to the Ukraine, which was first discovered in the UK, 6 years ago. It's now an invasive species spreading through rivers and canals. It breeds quickly, blocking pipes and drains and causing damage which can cost water companies millions of pounds. We find out more about the latest outbreak on the River Trent in Lincolnshire. And Mazuma, Mabuna, Namenia and Sessantina are all types of brassica, although you may not have heard of them before. We visit an organic market garden in Wiltshire where brassica salads and kales are the backbone of the business at this time of year. Presented by Anna Hill Produced for BBC Audio by Heather Simons

Quagga mussels are invasive shellfish that arrived in Utah in the boats of privately-owned watercraft trailered here from the Great Lakes. When left unchecked, they clog pipes and inlets to boats, pipelines and other lake infrastructure. They also cause great damage to native aquatic ecosystems. Sgt. Krystal Tucker with the Dept. of Wildlife Resources Aquatic Invasive Species Operations joins Nell and Chris on This Green Earth to talk about their program involving boat inspections for the mussels at some of the larger lakes in the state. How many they performed this past weekend and what they discovered.

Tannis Davidson is the curator of the Grant Museum of Zoology and Comparative Anatomy at University College London. From unearthing the dismembered arms of mummies at archaeological digs in Egypt to searching for fossils in Beijing, Tannis has a rich history in researching and examining the stories of the once living. As one of the few people in the world who takes care of animals only once they've died, Tannis' work has her looking after 68,000 specimens. One of the museum’s many accolades is that it houses one of only seven existing quagga skeletons in the world - a type of zebra that is now extinct. Other specimens include biological tissue from the Tasmanian tiger, an elephant tusk with an antique bullet encased within it, a gorilla skeleton which was once photographed hugging H.G.Wells… and a jar of moles!

Summer is approaching and owners of boats of all types are preparing to go on the water. This is perfect for zebra and quagga mussels, bivalves that travel between bodies of water by adhering to boat hulls. Idaho Matters talks with Nick Zurfluh, Invasive Species Section Manager with the Idaho State Department of Agriculture, about why these invasive species are detrimental to the balance of Idaho's water habitats.

FreeBSD Foundation July Newsletter, a bunch of BSDCan trip reports, HardenedBSD Foundation status, FreeBSD and OSPFd, ZFS disk structure overview, and more Spectre mitigations in OpenBSD. ##Headlines FreeBSD Foundation Update, July 2018 MESSAGE FROM THE EXECUTIVE DIRECTOR We’re in the middle of summer here, in Boulder, CO. While the days are typically hot, they can also be quite unpredictable. Thanks to the Rocky Mountains, waking up to 50-degree (~10 C) foggy weather is not surprising. In spite of the unpredictable weather, many of us took some vacation this month. Whether it was extending the Fourth of July celebration, spending time with family, or relaxing and enjoying the summer weather, we appreciated our time off, while still managing to accomplish a lot! In this newsletter, Glen Barber enlightens us about the upcoming 12.0 release. I gave a recap of OSCON, that Ed Maste and I attended, and Mark Johnston explains the work on his improved microcode loading project, that we are funding. Finally, Anne Dickison gives us a rundown on upcoming events and information on submitting a talk for MeetBSD. Your support helps us continue this work. Please consider making a donation today.

Plus, when I needed to move a jail from one data center to another, I would have to update routing tables across multiple sites. Not ideal. Enter dynamic routing… OSPF (open shortest path first) is an internal dynamic routing protocol that provides the autonomy that I needed and it’s fairly easy to setup. This article does not cover configuration of VPN links, ZFS, or Freebsd jails, however it’s recommended that you use seperate ZFS datasets per jail so that migration between hosts can be done with zfs send & receive. In this scenario, we have five FreeBSD servers in two different data centers. Each physical server runs anywhere between three to ten jails. When jails are deployed, they are assigned a /32 IP on lo2. From here, pf handles inbound port forwarding and outbound NAT. Links between each server are provided by OpenVPN TAP interfaces. (I used TAP to pass layer 2 traffic. I seem to remember that I needed TAP interfaces due to needing GRE tunnels on top of TUN interfaces to get OSPF to communicate. I’ve heard TAP is slower than TUN so I may revisit this.) In this example, we will use 172.16.2.0/24 as the range for OpenVPN P2P links and 172.16.3.0/24 as the range of IPs available for assignment to each jail. Previously, when deploying a jail, I assigned IPs based on the following groups: Server 1: 172.16.3.0/28 Server 2: 172.16.3.16/28 Server 3: 172.16.3.32/28 Server 4: 172.16.3.48/28 Server 5: 172.16.3.64/28 When statically routing, this made routing tables a bit smaller and easier to manage. However, when I needed to migrate a jail to a new host, I had to add a new /32 to all routing tables. Now, with OSPF, this is no longer an issue, nor is it required. To get started, first we install the Quagga package. The two configuration files needed to get OSPFv2 running are /usr/local/etc/quagga/zebra.conf and /usr/local/etc/quagga/ospfd.conf. Starting with zebra.conf, we’ll define the hostname and a management password. Second, we will populate the ospfd.conf file. To break this down: service advanced-vty allows you to skip the en or enable command. Since I’m the only one who uses this service, it’s one less command to type. ip ospf authentication message-digest and ip ospf message-diget-key… ignores non-authenticated OSPF communication. This is useful when communicating over the WAN and to prevent a replay attack. Since I’m using a VPN to communicate, I could exclude these. passive-interface default turns off the active communication of OSPF messages on all interfaces except for the interfaces listed as no passive-interface [interface name]. Since my ospf communication needs to leverage the VPNs, this prevents the servers from trying to send ospf data out the WAN interface (a firewall would work too). network 172.16.2.0/23 area 0.0.0.0 lists a supernet of both 172.16.2.0/24 and 172.16.3.0/24. This ensures routes for the jails are advertised along with the P2P links used by OpenVPN. The OpenVPN links are not required but can provide another IP to access your server if one of the links goes down. (See the suggested tasks below). At this point, we can enable the services in rc.conf.local and start them. We bind the management interface to 127.0.0.1 so that it’s only accessable to local telnet sessions. If you want to access this service remotely, you can bind to a remotely accessable IP. Remember telnet is not secure. If you need remote access, use a VPN. To manage the services, you can telnet to your host’s localhost address. Use 2604 for the ospf service. Remember, this is accessible by non-root users so set a good password. ###A broad overview of how ZFS is structured on disk When I wrote yesterday’s entry, it became clear that I didn’t understand as much about how ZFS is structured on disk (and that this matters, since I thought that ZFS copy on write updates updated a lot more than they do). So today I want to write down my new broad understanding of how this works. (All of this can be dug out of the old, draft ZFS on-disk format specification, but that spec is written in a very detailed way and things aren’t always immediately clear from it.) Almost everything in ZFS is in DMU object. All objects are defined by a dnode, and object dnodes are almost always grouped together in an object set. Object sets are themselves DMU objects; they store dnodes as basically a giant array in a ‘file’, which uses data blocks and indirect blocks and so on, just like anything else. Within a single object set, dnodes have an object number, which is the index of their position in the object set’s array of dnodes. (Because an object number is just the index of the object’s dnode in its object set’s array of dnodes, object numbers are basically always going to be duplicated between object sets (and they’re always relative to an object set). For instance, pretty much every object set is going to have an object number ten, although not all object sets may have enough objects that they have an object number ten thousand. One corollary of this is that if you ask zdb to tell you about a given object number, you have to tell zdb what object set you’re talking about. Usually you do this by telling zdb which ZFS filesystem or dataset you mean.) Each ZFS filesystem has its own object set for objects (and thus dnodes) used in the filesystem. As I discovered yesterday, every ZFS filesystem has a directory hierarchy and it may go many levels deep, but all of this directory hierarchy refers to directories and files using their object number. ZFS organizes and keeps track of filesystems, clones, and snapshots through the DSL (Dataset and Snapshot Layer). The DSL has all sorts of things; DSL directories, DSL datasets, and so on, all of which are objects and many of which refer to object sets (for example, every ZFS filesystem must refer to its current object set somehow). All of these DSL objects are themselves stored as dnodes in another object set, the Meta Object Set, which the uberblock points to. To my surprise, object sets are not stored in the MOS (and as a result do not have ‘object numbers’). Object sets are always referred to directly, without indirection, using a block pointer to the object set’s dnode. (I think object sets are referred to directly so that snapshots can freeze their object set very simply.) The DSL directories and datasets for your pool’s set of filesystems form a tree themselves (each filesystem has a DSL directory and at least one DSL dataset). However, just like in ZFS filesystems, all of the objects in this second tree refer to each other indirectly, by their MOS object number. Just as with files in ZFS filesystems, this level of indirection limits the amount of copy on write updates that ZFS had to do when something changes. PS: If you want to examine MOS objects with zdb, I think you do it with something like ‘zdb -vvv -d ssddata 1’, which will get you object number 1 of the MOS, which is the MOS object directory. If you want to ask zdb about an object in the pool’s root filesystem, use ‘zdb -vvv -d ssddata/ 1’. You can tell which one you’re getting depending on what zdb prints out. If it says ‘Dataset mos [META]’ you’re looking at objects from the MOS; if it says ‘Dataset ssddata [ZPL]’, you’re looking at the pool’s root filesystem (where object number 1 is the ZFS master node). PPS: I was going to write up what changed on a filesystem write, but then I realized that I didn’t know how blocks being allocated and freed are reflected in pool structures. So I’ll just say that I think that ignoring free space management, only four DMU objects get updated; the file itself, the filesystem’s object set, the filesystem’s DSL dataset object, and the MOS. (As usual, doing the research to write this up taught me things that I didn’t know about ZFS.) Digital Ocean ###HardenedBSD Foundation Status On 09 July 2018, the HardenedBSD Foundation Board of Directors held the kick-off meeting to start organizing the Foundation. The following people attended the kick-off meeting: Shawn Webb (in person) George Saylor (in person) Ben Welch (in person) Virginia Suydan (in person) Ben La Monica (phone) Dean Freeman (phone) Christian Severt (phone) We discussed the very first steps that need to be taken to organize the HardenedBSD Foundation as a 501©(3) not-for-profit organization in the US. We determined we could file a 1023EZ instead of the full-blown 1023. This will help speed the process up drastically. The steps are laid out as follows: Register a Post Office Box (PO Box) (completed on 10 Jul 2018). Register The HardenedBSD Foundation as a tax-exempt nonstock corporation in the state of Maryland (started on 10 Jul 2018, submitted on 18 Jul 2018, granted 20 Jul 2018). Obtain a federal tax ID (obtained 20 Jul 2018). Close the current bank account and create a new one using the federal tax ID (completed on 20 Jul 2018). File the 1023EZ paperwork with the federal government (started on 20 Jul 2018). Hire an attorney to help draft the organization bylaws. Each of the steps must be done serially and in order. We added Christian Severt, who is on Emerald Onion’s Board of Directors, to the HardenedBSD Foundation Board of Directors as an advisor. He was foundational in getting Emerald Onion their 501©(3) tax-exempt, not-for-profit status and has really good insight. Additionally, he’s going to help HardenedBSD coordinate hosting services, figuring out the best deals for us. We promoted George Saylor to Vice President and changed Shawn Webb’s title to President and Director. This is to help resolve potential concerns both the state and federal agencies might have with an organization having only a single President role. We hope to be granted our 501©(3) status before the end of the year, though that may be subject to change. We are excited for the formation of the HardenedBSD Foundation, which will open up new opportunities not otherwise available to HardenedBSD. ###More mitigations against speculative execution vulnerabilities Philip Guenther (guenther@) and Bryan Steele (brynet@) have added more mitigations against speculative execution CPU vulnerabilities on the amd64 platform.

Story 1 - The End of the Buffaloberry Seaon For the past 6 weeks or so, we have been talking about a bumper crop of buffaloberries. However, since they only last until the first frost of autumn, the berries have now disappeared and bears will be moving onto other fall foods. This means it is especially important to harvest and fruit trees you may have on your property as bears will be looking to replace the high calorie buffaloberries. This year has seen great crops of crab apples, nanking cherries, mountainash and even choke cherries and these can all attract bears that have been feeding near the townsite into the townsite. Let's try to keep our communities bear free. Story 2 - Whirling Disease Found in Johnson Lake This week officials confirmed the first case in Canada of whirling disease, in Johnson Lake in Banff National Park. This is devastating news on many levels. Johnson Lake is one of the few lakes in Banff that actually warms up in the summer to allow swimming and is always packed with people enjoying the water, whether swimming, paddling or picnicking. The lake is now closed until further notice until the extent of the infection within the larger Bow River watershed can be determined. Whirling disease affects the trout and whitefish in the area and can have devastating effects on fish populations. Story 3 - Quagga Mussels While whirling disease is here, likely to stay, quagga mussels is one of the potential invaders that has yet to find its way into Saskatchewan, Alberta and British Columbia. However, like whirling disease it is a one way introduction so both the Alberta government and Parks Canada are doing mandatory inspections of all watercraft visiting Alberta waterways. Let's keep Alberta quagga free! Story 4 - New Fossil Discoveries from the Burgess Shale Formations The Burgess Shales are one of the most important fossil beds on the planet. They represent perfect timing, around 550 million years ago, the time of the greatest explosion of life in the history of the planet. They also add unprecedented levels of preservation - even preserving animals that had no hard parts. This story looks way way way back into our ancestry.

As international trade increases, particularly by sea, we're seeing more stowaways; but not of the human variety. Scientists are reporting that animals and plants are hitching rides around the world on boats - and even on fishing tackle. They then setup home in other countries where, with nothing to eat them, they can become dangerously invasive. Timothy Revell spoke to David Aldridge an expert in invasive species about the UK's most recent arrival. Like this podcast? Please help us by supporting the Naked Scientists
