Current applications of species distribution models (SDM) are typically static, in that they are based on correlations between where a species has been observed (ignoring the date of the observation) and environmental features, such as long-term climate means, that are assumed to be constant for each site. Because of this SDMs do not account for temporal variation in the distribution of suitabl...

Obligate avian brood parasites can be host specialists or host generalists. In turn, individual females within generalist brood parasites may themselves be host specialists or generalists. The shiny cowbird Molothrus bonariensis is an extreme generalist, but little is known about individual female host fidelity. We examined variation in mitochondrial control region sequences from cowbird chicks...

Small intestinal lymphangioma is a rare benign tumor of the lymphatic system. Lymphangiomas account for 6% of small intestinal tumours seen in children but area smaller percentage, approximately 1.4–2.4% in adults.Here we describe the first case of small intestinal lymphangioma with bleeding in a 57-year-old woman. She presented with persistent gastrointestinal bleeding and Upper and lower endo...

The regional dialects or regiolects of the Rufous-collared Sparrow Zonotrichia capensis were compared between Campinas (47 degrees 06'W-22 degrees 90'S) and Botucatu (48 degrees 44'W-22 degrees 88'S), São Paulo State, Southeastern Brazil. Songs of 88 individuals from thirteen localities were recorded. Sonograms showed that two areas presented more homogeneous songs, forming two regiolects. In 1...
