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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
