The potential consequences of anthropogenic habitat fragmentation on species diversity and extinction have drawn considerable attention in recent decades. In many cases, traditional island biogeography theory has been applied to explain the observed patterns. Here, we propose that habitat fragmentation as a selective force can be traced in mammalian body length changes. By exploring historical sources, we are able to show that the body length of Danish mammals has altered over a period of 175 years, possibly in response to increasing habitat fragmentation. The rate of body length change was generally lowest in medium-sized mammals, and increased with both smaller and larger body mass. Small mammals have generally increased, whereas large mammals have...

ABSTRACT Traffic of heavy machinery at harvest and log extraction causes structural degradation of the soil, but studies on the effects of forest harvesting on soils with high organic matter content and exchangeable Al are scarce. The objective of this study was to evaluate the effect of mechanized forest harvesting operations on a Dystric Cambisol (Humic) with high organic matter (more 50 g kg1) content and exchangeable Al (more 6,0 cmolc kg-1), reforested with Pinus taeda L. The evaluated harvesting system were the whole-tree, in which the feller-buncher cuts and lays the trees down in bundles; the skidder drags the tree bundles up near a road; and the harvester delimbs and cuts the trees into short logs, stacking them on the roadside to be loaded onto...

MORPHOLOGY AND CONSERVATION OF THE MESOAMERICAN SLIDER (Trachemys venusta, EMYDIDAE) FROM THE ATRATO RIVER BASIN, COLOMBIA
Provedor de dados: 37
Autores: CEBALLOS,CLAUDIA P.; BRAND,WILLIAM A.
The phylogenetic relationships of the Mesoamerican Slider, Trachemys venusta, that inhabits the Atrato River basin of Colombia have been controversial as three different names have been proposed during the last 12 years: T. v. venusta, T. v. uhrigi, and T. ornate venusta. Using a group of sliders that was confiscated by the regional authority we compared the morphology of T. venusta distributed in the Atrato River with the morphology of the subspecies putatively distributed in Colombia. We found that the Colombian Mesoamerican slider has an overall smaller size, different plastral inter-scute seam formula, and different head, carapace and plastron coloration patterns. In addition, we also report the poor health condition of these individuals that have...

INTRODUCTION: Despite the growing interest in the study of Gram-negative bacilli (GNB) infections, very little information on osteomyelitis caused by GNB is available in the medical literature. OBJECTIVES AND METHODS: To assess clinical and microbiological features of 101 cases of osteomyelitis caused by GNB alone, between January 2007 and January 2009, in a reference center for the treatment of high complexity traumas in the city of São Paulo. RESULTS: Most patients were men (63%), with median age of 42 years, affected by chronic osteomyelitis (43%) or acute osteomyelitis associated to open fractures (32%), the majority on the lower limbs (71%). The patients were treated with antibiotics as inpatients for 40 days (median) and for 99 days (median) in...
