Over the course of the annual cycle, migratory bird populations can be impacted by environmental conditions in regions separated by thousands of kilometers. We examine how climatic conditions during discrete periods of the annual cycle influence the demography of a nearctic-neotropical migrant population of yellow warblers (Setophaga petechia), that breed in western Canada and overwinter in Mex...

Intravascular lymphomatosis (IVL) is a rare angiotrophic large cell lymphoma producing vascular occlusion of arterioles, capillaries, and venules. Antigenic phenotyping shows that these lymphomas are mostly of B cell type, and less commonly T cell or Ki-1 lymphomas. The central nervous system and skin are the two most commonly affected organs; patients usually present with progressive encephalo...

The ongoing loss of biodiversity caused by rapid climatic shifts requires accurate models for predicting species' responses. Despite evidence that evolutionary adaptation could mitigate climate change impacts, evolution is rarely integrated into predictive models. Integrating population genomics and environmental data, we identified genomic variation associated with climate across the breeding ...

to the iron work. Its feet had evidently slipped, and when found by the mother some time afterwards, it was quite unconscious. The head had fallen to one side, tongue was protruded and the face had many petechia over it. There was a good deal of foam round the mouth. A medical man, who happened to be at hand, started artificial respiration, and the restoration of breathing was followed by gener...

respirations were rapid, and he complained of pain in the chest and constant cough. The temperature was 102?, and the tongue heavily furred; there was no bubo at this time. The physical signs were those of pneumonia in an early stage, which I accordingly prescribed for. On arriving at the hospital the next day, I was informed that the patient had died suddenly about two or three hours after my ...

We report on a female neonate with severe onset of congenital cytomegalovirus (CMV) infection. She was noted to have cerebral ventriculomegaly on antenatal ultrasound, and presented with petechia after birth. Laboratory tests revealed severe thrombocytopenia (platelet count, 11,000/mm3) and hypoglycemia (serum glucose level, 5 mg/dl). Hepatosplenomegaly with elevated hepatic enzymes, retinitis,...

borne disease caused by Nairovirus group of the Bunyaviridae family. Infection is transmitted to humans by Hyalomma ticks or by direct contact with the blood or tissues of infected humans or viraemic livestock1. CCHF virus has a wide geographic distribution, circulating in Africa, the Middle East, Asia, and Central and SouthEastern Europe2. CCHF first emerged in Turkey in 2002, and the prevalen...

Using morphological or behavioural features correlated with paternal care, females can, prior to mating, assess the potential parental contribution of males. As a first step in a study of female mate choice in yellow warblers, this study was designed to examine the importance of paternal care by males of differing chest striping. Contrary to a previous report, paternal care was not negatively c...
