Seals quickly respond to gain and loss of habitat under climate change
... "The seals that discovered the new breeding site had things good, because food was abundant and nearby, however when the ice returned, the new colony collapsed
and only a few seals made it back to their original home.
"This illustrates the importance of understanding the behaviour and life history of a ...
Robo-bats with metal muscles may be next generation of remote control flyers
... Tiny flying machines can be used for everything from indoor surveillance to exploring collapsed

Eastern Pacific tuna hang in the balance
... a single measure to address overfishing.
Too many fishermen chasing too few fish is a scenario that has been repeated for decades as a prelude to collapsed
