Salty Cinema Livestream Event

As communities around the world adjust in response to the global pandemic, our oceans are also responding – from sea turtles nesting on once crowded beaches to ocean noise and emissions slowing down.

Join us Tuesday, May 19th at 6 PM Pacific for a livestream event with an expert panel discussing how decreased human activity in our oceans and coasts can provide lessons for future marine research, policy, and conservation.

“Checking in with our Oceans Amidst a Global Shutdown”

Hosted by:  Dr. Stuart Sandin, Director of CMBC

Speakers include:
Dr. Jessica Meir, Astronaut/NASA
Dr. Nancy Knowlton, Sant Chair in Marine Science/ Smithsonian
Heather Zichal, Executive Director/Blue Prosperity
Dr. Emanual Goncalves, Chief Scientist/Ocean Azul Foundation
Brad Nahil, Director/SEE Turtles

Where’d You Get Those Genes? Individual Growth Can Vary Wildly When Populations Interbreed

From the lab of Dr. Ronald Burton:
Scientists find that interactions between different types of DNA determine hybrid fitness

“When individuals from different populations of the same species interbreed, there is often ‘hybrid vigor’ in the first generation, meaning that the offspring have improved function and fare well,” said Ron Burton, a professor of marine biology at Scripps. However, when this generation produces offspring, the second generation hybrids show a range of fitness levels – in this study defined as growth rate – with many doing quite poorly. 

These findings from this study have broad implications for conservation initiatives in which people introduce or move formerly separated populations, and as populations migrate due to climate change and other environmental stressors. Although each population may be intrinsically healthy, incompatibilities between DNA types between populations may result in reduced fitness when populations interbreed.

Resource for teachers and home school

Enjoy, a month of short daily videos (quests) to understand and celebrate our natural world.  

#EarthSchool is in session!
It is aimed – during this time of lockdown to help show off the wonder and mystery of our planet to our children through a daily, immersive environmental adventure from @UNEP (United Nations Environment Program), @TED_ED and partners: https://bit.ly/Earth-School
