It was tragic stories such as these that prompted a group of researchers from the University of San Diego, UC Berkeley and Yale to embark on a broad review of all the reports of large animal die-offs in the scientific literature since the middle of the last century. They turned up 727 such papers documenting "mass mortality events" (MME) of 2,407 global populations of mammals, birds, fish, reptiles, amphibians and marine invertebrates -- like the thousands of starfish that perished in North America in 2014.
Their analyses, published this week in the Proceedings of the National Academy of Sciences, revealed that not only are these events becoming more frequent, they're also increasing in magnitude, with the number of fatalities higher for birds, fish and marine invertebrates. Thirty-five events completely or nearly wiped out an entire population.
