Faced with earlier studies stating that the big predators such as tigers, lions, and lynxes fulfil their dietary needs by eating one or two types of prey, scientists from the University of Malaga assure us now that felines need from 5 to 7 different types of prey to fulfil their dietary needs, although they may be more specialised anatomically than the canines (wolves, dogs?) who can obtain 100% ingested biomass by eating three types of prey. This study brings new keys to the paleoecology of the big predators from the past, such as sabre-toothed tigers. http://www.physorg.com/news134982580.html Biology Fri, 11 Jul 2008 08:09:40 EST news134982580 Measuring and testing the teeth of living primates could provide a window into the behavior of the earliest human ancestors, based on their fossilized remains. Research funded by the National Science Foundation and led by University of Arkansas anthropologist Michael Plavcan takes us one step closer to understanding the relationship between canine teeth, body size and the lives of primates. http://www.physorg.com/news133709182.html Other Sciences Thu, 26 Jun 2008 14:26:22 EST news133709182
