Última Geographic variation in skull shape of the water rat Scapteromys tumidus (Cricetidae, Sigmodontinae): isolation-by-distance plus environmental and geographic barrier effects? Anais da ABC (AABC) QUINTELA,FERNANDO M.; FORNEL,RODRIGO; FREITAS,THALES R.O.. ABSTRACT The geographic variation in skull size and shape of the swamp rat Scapteromys tumidus was examined in samples from eight geographic clusters in almost of its distribution in southern Brazil and Uruguay. For analysis we used two-dimensional geometric morphometric methods for dorsal, ventral and lateral views of the skull. The geometric descriptors showed no significant differences in skull size between geographic clusters, while differences in shape were highly significant. We found a significant and moderate correlation between geographic and morphological distances, corroborating the isolation-by-distance model. Samples from the Rio Grande do Sul central coastal plain were the most differentiated, segregating completely from all other samples in...

In natural history collections throughout Europe, there are many old lion specimens of unknown origin. If these specimens can be shown to have originated from now-extinct populations their value would significantly increase, as would the value of the collections. Recently, a 200-year old mounted skeleton in the Zoological Museum Amsterdam has been identified as the extinct Cape lion Panthera leo melanochaita (Smith, 1842), based primarily on morphological information inferred from a painting of this specimen while it was still alive. To test this hypothesis, we used ancient DNA (aDNA) techniques to extract and sequence mitochondrial DNA (mtDNA) from this specimen, and compared the genetic results with previously published lion mtDNA sequences. Our results... Tipo: Article / Letter to the editor Palavras-chave: India; Mitochondrial DNA; Panthera leo; Skull morphology; South Africa; 42.84.
