After three years of silence, I am proud to share this new edition with you. We are already working on our next edition and will do our best to publish one issue per year. But this will depend on you! We are looking forward to receiving your articles, thesis abstracts, notes from the field, news items, and any other information related to the conservation of xenarthrans that you would like to publish in our Newsletter. In 2009, our Specialist Group underwent several important changes: With the beginning of the 2009–2012 period, our Specialist Group has been renamed to the IUCN/SSC Anteater, Sloth and Armadillo Specialist Group (ASASG). This new name is intended to make it more com- prehensible for the general public, which will facilitate promotion of our activities. Gustavo Fonseca stepped down as our Chair after almost 20 years. This Specialist Group would not exist with- out Gustavo’s dedication to the conservation of xenarthrans, and I can’t thank him enough for his excellent job! I am very honored that Simon Stuart, the Chair of the IUCN Species Survival Commission, invited me to take over the Chairmanship from Gustavo, and will do my best to strenghten our Group and promote the conserva- tion of xenarthrans. I am extremely happy that Flávia Miranda accepted serving as our Deputy Chair; it is a pleasure to work with her! Agustín M. Abba is our Specialist Group's new Red List Authority. He is of great help during daily opera- tions of our Group, and I am delighted to have him on our team. I have no doubt that our Group will benefit greatly from Flávia's and Agustin's participation! The list of members has been completely revised. I would like to thank our past members for their dedication to the conservation of xenarthrans. At the end of this letter, you will finda list of the ASASG members for the 2009–2012 period. I’m looking forward to working with all of you! Parallel to the change in the new leadership, the ASASG’s headquarters have been moved from Washington, DC to Mendoza, Argentina. I would like to take the chance to thank everyone at Conservation International for the invaluable logistical, administrative, and financial support our Group has received over the past years. Edentata underwent quite a few changes. Some of them are already included in this edition, while others will follow in future volumes. The new editorial staff would like to thank the previous editors Gustavo Fonseca, Anthony Rylands and John M. Aguiar, for their work. Due to financial and ecological reasons, we have decided to convert Edentata into an electronic journal. Please help us spreading the news about Xenarthra conservation by sending this electronic version to your colleagues! We also have a new website, <http://www.xenarthrans.org> — please read more about it in the News section of this edition! And last, but not least, I would like to extend my special thanks to our former coordinator John Aguiar; he’s been of invaluable help over all these years. Enjoy this new issue of Edentata!

    BOL MUS BIOL MELLO LEITÃO (N SÉR) 15:41-46 JUNHO DE 2003 41 A note on the climbing abilities of giant anteaters, Myrmecophaga tridactyla (Xenarthra, Myrmecophagidae) Robert J Young1*, Carlyle M Coelho2 and Dalía R Wieloch2 ABSTRACT: In this note we provide seven observations of climbing behaviour by giant anteaters Five observations were recorded in the field: three of giant anteaters climbing on top of 15 to 20 metre high termite mounds, and two observations of giant anteaters in trees In these cases the animals were apparently trying to obtain food The other two observations are from captivity, one involves a juvenile animal that several times over a three month period climbed in a tree to the height of around 20 metres The final observation, involves an adult female that after being separated from her mother climbed on two occasions over a wall with a fence on top (total height 2 metres) to be reunited with her mother It therefore seems that, despite the fact only one other record of climbing behaviour by giant anteaters exists in the scientific literature that giant anteaters have the ability to climb It also may be the case that young adults are highly motivated to stay with their mothers Key words: giant anteater, Myrmecophaga tridactyla, climbing behaviour, wild, zoos RESUMO: Nota sobre as habilidades trepadoras do tamanduá-bandeira, Myrmecophaga tridactyla (Xenarthra, Myrmecophagidae) Nesta nota apresentamos sete registros de comportamento de subir expressado por tamanduá-bandeira Temos cinco exemplos da natureza: três de tamanduás-

Israel News All Germany - Israel Lebanon war Iran Gaza plan State of the Union Poland - Holocaust Log in Scientists had thought that the silky anteater was a single species. Now having actually looked at the tiny animals, who spend most of their lives asleep in trees in remote parts of Central and South America, they realize there are seven species. At least. Following a decade of expeditions and analysis, a Brazilian team reports on the validation of three previously suspected silky anteater species and the addition of three more in the Zoological Journal of the Linnean Society. Altogether with the originally known one, that makes seven silky anteaters. There could be dozens of species of silky anteaters – who knows. Not a lot of zoologists live in rain forest treetops and these things are strictly nocturnal, and small. Not that the animals, also called pygmy anteaters, are easy to see in broad sunlight.

MacPhee2* The living tree sloths Choloepus and Bradypus are the only remaining members of Folivora, a major xenarthran radiation that occupied a wide range of habitats in many parts of the western hemisphere during the Cenozoic, including both continents and the West Indies. Ancient DNA evidence has played only a minor role in folivoran systematics, as most sloths lived in places not conducive to genomic preservation. Here we utilize collagen sequence information, both separately and in combination with published mitochondrial DNA evidence, to assess the relationships of tree sloths and their extinct relatives. Results from phylo- genetic analysis of these datasets differ substantially from morphology-based concepts: Choloepus groups with Mylodontidae, not Megalonychidae; Bradypus and Megalonyx pair together as megatherioids, while monophyletic Antillean sloths may be sister to all other folivorans. Divergence estimates are consistent with fossil evidence for mid-Cenozoic presence of sloths in the West Indies and an early Miocene radiation in South America. he sloths (Xenarthra, Folivora), nowadays a taxonomically consensus8–10,16,17 in morphology-based phylogenetic treatments is narrow (six species in two genera) component of the fauna of to place the three-toed sloth as sister to all other folivorans (Fig.

ABSTRACT: Pilosa include anteaters (Vermilingua) and sloths (Folivora). Modern tree sloths are represented by two genera, Bradypus and Choloepus (both around 4–6 kg), whereas the fossil record is very diverse, with approximately 90 genera ranging in age from the Oligocene to the early Holocene. Fossil sloths include four main clades, Megalonychidae, Megatheriidae, Nothrotheriidae, and Mylo- dontidae, ranging in size from tens of kilograms to several tons. Modern Vermilingua are represented by three genera, Cyclopes, Tamandua and Myrmecophaga, with a size range from 0.25 kg to about 30 kg, and their fossil record is scarce and fragmentary. The dependence of the body size on phylo- genetic pattern of Pilosa is analysed here, according to current cladistic hypotheses.
