This audio segment from PRI's The World Science Podcast explores the plight of the rising numbers of migrants, in the South Asian nation of Bangladesh, forced to leave their homes because of climate changes.
Ecologists are investigating whether Weddell seal pups that spend more time in the water learning to swim with their moms have a higher chance of surviving to return and have pups of their own. Weddell seals live all their lives in Antarctica, and are the southernmost mammal in the world. Weddell moms spend a lot of time with their pups coaxing them into the cold Antarctic water and helping them learn to swim. Footage includes interviews with Montana State University ecology professors Bob Garrott and Jay Rotella. Video production by Mary Lynn Price. Additional footage by Jessica Farrer, Jesse DeVoe, Henry Kaiser, Rob Robbins, and Steve Rupp.
The resilient Weddell seals of Erebus Bay in Antarctica's Ross Sea, and how they responded to a massive iceberg event that blocked access to some of their pupping areas in the past decade. These seals are the southernmost mammal on Earth, and are the subject of one of the longest running population studies ever of a long-lived mammal.
Video includes interviews filmed in Antarctica with Montana State University ecologists Jay Rotella, Bob Garrott, and Thierry Chambert. Footage and images contributed by Mary Lynn Price, Henry Kaiser, Jay Rotella, Bob Garrott, Don Siniff, Gillian Hadley, Rob Robbins, Steve Rupp, Jesse DeVoe, Glenn Stauffer, Jessica Farrer, Jen Mannas, and Thierry Chambert. Video editing by Mary Lynn Price. Opening music composed by Darren Roberts, piano by Rachel Carlson.
