It turns out that alligators do not live on meat alone. Neither do Nile crocodiles. A new study led by the Wildlife Conservation Society says that the American alligator and a dozen other crocodile species enjoy an occasional taste of fruit along with their normal meat-heavy diets of mammals, birds, and fish.
PLEASE PASS THE FRUIT -- A new WCS-led study says American alligators (pictured) and 12 other crocodilians consume fruit, in addition to their usual meat heavy diets.

The study gives new insight into the possible role that crocodilians, some of which have large territories, may play in forest regeneration through digesting and passing seeds from fruits.
The study appears in the July issue of the Journal of Zoology. Authors include: Steven Platt of the Wildlife Conservation Society; Ruth M. Elsey of the Louisiana Department of Wildlife and Fisheries; Hong Liu of Florida International University and the Fairchild Tropical Botanic Garden; Thomas R. Rainwater of the U.S. Fish and Wildlife Service; James C. Nifong of the University of Florida; Adam E. Rosenblatt and Michael R. Heithaus of Florida International University; and Frank J. Mazzotti of University of Florida.
The authors looked at 18 species of crocodilian ranging from the American alligator to the fearsome Nile crocodile and found 13 of the species consumed some form of fruit including a variety of berries, legumes, nuts, and grains.
While the authors say some of the fruit ingestion may have been incidental to prey capture, evidence shows that other fruit is consumed deliberately and in large quantities. Much remains to be learned about how crocodilians process carbohydrates and other plant-based nutrients, though studies suggests that fruit eating is likely to yield nutritional rewards for crocodilians.
"Although underreported, fruit eating appears widespread among crocodilians," said the study's lead author, Steven Platt of the Wildlife Conservation Society. "Given the biomass of crocodiles in many subtropical and tropical wetlands and their capacity for ingesting large numbers of fruits, we consider it likely that crocodilians function as significant seed dispersal agents in many freshwater ecosystems."
The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. Visit http://www.wcs.org.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
