1. Diversidade, diferenciação e biogeografia de pequenos mamíferos não-voadores na Mata Atlântica ao norte do rio São Francisco Centro de Endemismo Pernambuco / Diversity, differentiation and biogeography of non-volant small mammals of the Atlantic Forest north of São Francisco river - Pernambuco Endemism Center
The Brazilian tropical rainforests (Amazon and Atlantic Forest) present high species diversity and are currently separated by a belt of open and dry vegetation. Part of this belt is occupied by the Caatinga, where are found the Brejos de Altitude, evidence of the historical connections between the Atlantic Forest and the Amazon. The Pernambuco Endemism Cente

2. Purificação e caracterização de uma ß-N-acetillhexosaminadase extraída do mamífero marinho Sotalia fluviatilis
This report shows 2232 times purification of a βNAcetylhexosaminidase from hepatic extracts from the sea mammal Sotalia fluviatilis homogenate with final recovery of 8,4%. Sequenced steps were utilized for enzyme purification: ammonium sulfate fractionation, Biogel A 1.5 m, chitin, DEAESepharose and hydroxyapatite chromatographies. The protein molecular

3. Causes and consequences of marine mammal population declines in southwest Alaska: a food-web perspective
Populations of sea otters, seals and sea lions have collapsed across much of southwest Alaska over the past several decades. The sea otter decline set off a trophic cascade in which the coastal marine ecosystem underwent a phase shift from kelp forests to deforested sea urchin barrens. This interaction in turn affected the distribution, abundance and product

4. Niches, body sizes, and the disassembly of mammal communities on the Sunda Shelf islands
The rising sea level at the end of the Pleistocene that created the islands of the Sunda Shelf in Indonesia and Malaysia provides a natural experiment in community disassembly and offers insights into the effects of body size and niches on abundance, distribution, and diversity. Since isolation, terrestrial mammal communities of these islands have been reduc

5. Ötzi's last meals: DNA analysis of the intestinal content of the Neolithic glacier mummy from the Alps
Samples of the intestinal content were collected from the ileum and colon of the Neolithic glacier mummy popularly known as the Tyrolean Iceman, or Ötzi. DNA was extracted from the samples and PCR amplified, using a variety of primer pairs designed to bind to different genes (mammal mitochondrial 12S ribosomal RNA gene, plant/fungal nuclear 18S ribosomal RN
