One bighorn sheep died with acute pneumonia 90 days after ...

Tree survival plays a central role in forest ecosystems. Although many factors such as tree size, abiotic and biotic neighborhoods have been proposed as being important in explaining patterns of tree survival, their contributions are still subject to debate. We used generalized linear mixed models to examine the relative importance ...

Varicella is a common and mild disease in healthy children.
