 <\/p>\n

A common reproductive strategy among invertebrates called multiple paternity could give animals like porcelain crabs a survival advantage as the world grows warmer, new research finds.<\/p>\n

While climate change is often associated with major events like melting glaciers and super storms, the authors of the recently published paper in the Journal of Crustacean Biology chose to look through a much smaller lens. Porcelain crabs served as the bellwether because they cannot migrate away from extreme weather, unlike other coastal species like fish or dolphins.<\/p>\n

Specifically, the team was curious about the effects of extreme heat on multiple males fertilizing the same brood. Under ordinary circumstances, multiple paternity diversifies the gene pool and increases the hardiness of offspring. Now, new research shows temperature swings actually produces crabs with 24 times more fitness than previous generations.<\/p>\n

\u201cThrough our research we\u2019ve seen that this phenomenon is crucial to the survival strategy of these species,\u201d said Seabird McKeon, Ph.D., a biodiversity scientist with the UCF Lewis Lab of Applied Coastal Ecology, co-author of the paper, along with T.J. Yockachonis, the Smithsonian National Museum\u2019s Amanda Windsor, Ph.D., and Jonathon Stillman, Ph.D., of the University of California, Berkley.<\/p>\n

Yockachonis, a marine biology Ph.D student at Washington State University, took the lead on the publication as his master\u2019s thesis. McKeon\u2019s supportive role helped sponsor Yockachonis throughout his research.<\/p>\n

\u201cMy role was providing expertise on crustaceans and marine organisms,\u201d said McKeon. \u201cT.J. and I looked at this information together.\u201d<\/p>\n

McKeon hopes the research will continue to shed a light on climate change and how it directly affects often unseen organisms.<\/p>\n

\u201cWe hope it will lend a different perspective on how we can look at climate change and its effects,\u201d McKeon said.<\/p>\n","protected":false},"excerpt":{"rendered":"
