Land and sea species differ in climate change response: study
Land and sea species differ in climate change response: study
So for land animals it is going to be more about where there's enough water to drink and grow the plants to eat (or to feed the herbivores they eat), whereas for marine life its about pH, pretty specific temperature ranges and where the food is. Seems reasonable.
Land and sea species differ in climate change response: study
(Phys.org) -- Marine and terrestrial species will likely differ in their responses to climate warming, new research by Simon Fraser University and Australias University of Tasmania has found.
...We think a combination of things is going on, says Amanda Bates, co-author from the University of Tasmanias Institute of Marine and Antarctic Studies (IMAS). A species niche isnt just set by temperature. On land where water is key, species may be hindered more by dryness rather than being too hot at this range boundary.
Second, it could be that rare heat waves are actually setting boundaries on where species can live. Finally, as Charles Darwin pointed out over 150 years ago, there may be more species and much more ecological competition toward the tropics, which may be enough to exclude species from living in the warmer end of their potential real estate.
...The team concludes by pointing out that while chaotic species combinations may be bad news for animals on land, entire assemblages of species are likely to shift in the ocean, meaning researchers can make better predictions about how marine species redistribute in the face of climate change.
