Clinical studies of erythrocyte outcomes and mortality: size really counts.

10 January 2013 O VER the past years, an increasing number of studies report adverse outcomes associated with transfused blood components. Of this extensive and growing literature, outcomes after erythrocyte transfusions are the most numerous. Although erythrocytes are licensed for storage up to 42 days, reports suggest that units stored longer than 14–21 days may potentially be associated with...

Latitudinal and climatic variation in body size and dorsal scale counts in Sceloporus lizards:a phylogenetic perspective.

Squamates often follow an inverse Bergmann's rule, with larger-bodied animals occurring in warmer areas or at lower latitudes. The size of dorsal scales in lizards has also been proposed to vary along climatic gradients, with species in warmer areas exhibiting larger scales, putatively to reduce heat load. We tested for these patterns in the diverse and widespread lizard genus Sceloporus. Among...

N-mixture models for estimating population size from spatially replicated counts.

Spatial replication is a common theme in count surveys of animals. Such surveys often generate sparse count data from which it is difficult to estimate population size while formally accounting for detection probability. In this article, I describe a class of models (N-mixture models) which allow for estimation of population size from such data. The key idea is to view site-specific population ...

Estimating chimpanzee population size with nest counts: validating methods in Taï National Park.

Successful conservation and management of wild animals require reliable estimates of their population size. Ape surveys almost always rely on counts of sleeping nests, as the animals occur at low densities and visibility is low in tropical forests. The reliability of standing-crop nest counts and marked-nest counts, the most widely used methods, has not been tested on populations of known size....
