Podcasts about sea star wasting disease

The largest non-commercial marine mass mortality event on record (as of 2013) created a ‘natural experiment’ and an opportunity to study genomic changes in wild populations with unprecedented detail. Rather than observing only the aftermath—a team of researchers from UC Merced is reconstructing the population and genetic consequences of an epidemic outbreak of sea star wasting disease. The team measured the abundance and genetic variation of Pisaster ochraceus, a keystone species, in the year preceding mass mortality. They then repeated sampling of adults and juveniles in subsequent years, measuring population dynamics and genomic shifts during and after the disease outbreak. At a time when marine diseases and mass mortalities are on the rise, this study documents the impact of little-known wildlife diseases and potential trajectory of recovery in a keystone marine species.

Did I ever tell you that this is my favourite day of the week? We have another episode of Ocean Talk Friday with myself, Andrew Lewin, and Nathan Johnson. We choose 4-5 articles that we feel made a big impact this past week and talk about them, their science and their conservation implications.  Today we discussed the following: 1) The resurgence of the Ross Sea MPA proposal; 2) Mussels smell before they settle; 3) Mussels battling Ocean Acidification with Food; 4) Researchers find out more about the Sea Star Wasting Disease; and, 5) 5 Pacific Islands disappear into the Ocean due to Climate Change.   Speak Up For Blue TV: http://bit.ly/sufbtele Support the Podcast: http://www.speakupforblue.com/patreon Shop for the Ocean: http://www.speakupforblue.com/shop 10 Ocean Tips to Conserve the Ocean: http://www.speakupforblue.com/wordpress/sufb_optinpdf Show Notes: http://www.speakupforblue.com/session158
