” “Our results also suggest that the Arctodus simus population located in southern North America was more omnivorous than the highly carnivorous populations in the northwest,” he adds. Specifically, after analysis with microscopic techniques and virtual models developed by the UA researcher, carious lesions caused by carbohydrates, present in vegetables, have been found in the dental remains found at the Rancho La Brea site in Los Angeles (California). . “One of the most paradigmatic places for the study of fossil mammals during the Pleistocene in North America”, as described by Alejandro Romero. “This is an interesting research – explains the researcher from the University of Alicante – since caries have been registered for the first time in the remains of Arctodus simus teeth , showing that it could be adapted to plant resources in its diet derived from

climatic changes or competition with other Rwanda Email List predators ”. This work has also counted on other experts in vertebrate paleontology and ecology such as Alejandro Pérez-Ramos from the UMA and researchers from the Museum of Natural History and the Museum of Rancho La Brea de los Ángeles (USA). Reference An international study with the participation of the Higher Council for Scientific Research (CSIC) contributes to understanding the patterns of domestication and dispersal of fruit species in the American continent and to distinguish what role the already extinct herbivorous megafauna (giant sloths, giant armadillos and mastodons have had) , among others) and humans. The work, which is published in the journal PNAS , analyzes a database with information on the distribution of 130 fruit species such as cacao, cashew, chicozapote (gum tree), pineapple or

species close to custard apple. About 12,000 years ago, the megafauna became extinct in America, mainly due to human colonization of the continent. These animals naturally dispersed many of the continent’s fruit species. With their extinction there was a risk that many of them would disappear but this work reveals that the use of many of these plant species by humans has been able to reverse the extinction. “Through different statistical analyzes we have studied the distribution of different fruit species based on whether or not they have been used by humans since the megafauna became extinct,” says CSIC researcher Iñaki Hormaza, who works at the Institute of La Mayora Subtropical and Mediterranean Horticulture. The study shows that the American cultures used a great diversity of fruit trees, in fact, approximately three quarters of the species dispersed by the m
