Interesting piece about the impact of the changing environment and how it's affecting various species. :(
The rising ocean temperatures that may come with climate change pose a threat to fish that live near the equator, a new study from Australia suggests.
Researchers analyzed how six tropical fish species might behave in ocean temperatures that are 2 to 3 degrees Celsius (3.6 to 5.4 degrees Fahrenheit) warmer than their current habitats — a change that is expected to happen by the end of this century. It turned out that the warmer the temperature, the harder it was for the fish to swim, find food, evade predators and reproduce.
"Organisms that live in extreme latitudes near the equator are particularly vulnerable to temperature because they evolved in a very narrow range of temperatures," said study researcher Jodie Rummer, a research fellow at James Cook University in Queensland. source: http://www.sciencealert.com.au/news/20141702-25249.html (http://www.sciencealert.com.au/news/20141702-25249.html)
I guess it's pretty fluid in that where waters do warm, then some fish will migrate as habitats change. Makes you think for sure and reminds one of how delicate it all is!
