The study, published this week in Nature Climate Change, provides insights into why and how species are moving around theglobe in response to global warming. Researchers gathered published data from tests determining thephysiological temperature limits -- tolerance to heating andcooling levels -- on 169 cold-blooded marine and terrestrialspecies, then compared the data with the regions the speciesinhabit. They found that while marine animals closely conformed to thetemperature regions they could potentially occupy, terrestrialspecies live farther from the equator than their internalthermometers suggest they can live. In other words warmtemperatures aren't limiting them from living in closer to theequator.
"Finding that marine and terrestrial species are limited bytheir cold tolerance suggest that warming will allow expansions ofanimals towards the poles to take advantage of newly opened uphabitats," says lead author Jennifer Sunday, a biologist fromSimon Fraser University, Canada. "However because land animals are not limited by heat to thesame extent as marine animals, patterns of retreat in the hottestregions of species' ranges may differ between land and sea." The research team found that while both the cold and warmboundaries of marine species are marching towards the poles,terrestrial species have been less responsive at their warm versustheir cold range boundaries. "We think a combination of things is going on," saysAmanda Bates, co-author from the University of Tasmania's Instituteof Marine and Antarctic Studies (IMAS). "A species niche isn'tjust set by temperature.
On land where water is key, species may behindered more by dryness rather than being too hot at this rangeboundary. "Second, it could be that rare heat waves are actually settingboundaries on where species can live. Finally, as Charles Darwinpointed out over 150 years ago, there may be more species and muchmore ecological competition toward the tropics, which may be enoughto exclude species from living in the warmer end of their potentialreal estate." The authors call for research to better understand how climatechange will affect animals, especially those on land wherepredicting responses to warming may be particularly difficult. "Terrestrial species ranges may stretch towards the poles --expanding their cold range boundaries but responding erratically attheir warm boundaries," says Nicholas Dulvy, a marinebiologist at SFU.
"These individuals will be overrun by the 'pole-wards' marchas other species enter their territories. So we will see all sortsof new ecology as species come into contact and interact as neverbefore." The team concludes by pointing out that while chaotic speciescombinations may be bad news for animals on land, entireassemblages of species are likely to shift in the ocean, meaningresearchers can make better predictions about how marine speciesredistribute in the face of climate change.
