Chlorinated and non-chlorinated solvents are used in a variety of industrial processes and as a consequence, they have become environmental contaminants as well. Because of this, they lead to both occupational and environmental exposures. Exposure to these compounds can potentially result in various forms of neurological damage with a wide...
Social information is used widely in breeding habitat selection and provides an efficient means for individuals to select habitat, but the population-level consequences of this process are not well explored. At low population densities, efficiencies may be reduced because there are insufficient information providers to cue high-quality habitat. This constitutes...

• Premise of the study: The dramatic advances offered by modern DNA sequencers continue to redefine the limits of what can be accomplished in comparative plant biology. Even with recent achievements, however, plant genomes present obstacles that can make it difficult to execute large-scale population and phylogenetic studies on next-generation...

Condors and vultures are distinct from most other terrestrial birds because they use extensive soaring flight for their daily
movements. Therefore, assessing resource selection by these avian scavengers requires quantifying the availability of
terrestrial-based habitats, as well as meteorological variables that influence atmospheric conditions necessary for soaring. In
this study,...

Winter climate is expected to change under future climate scenarios, yet the majority of winter ecology research is focused in cold-climate ecosystems. In many temperate systems, it is unclear how winter climate relates to biotic responses during the growing season. The objective of this study was to examine how winter...

Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists...

Zebrafish are a powerful model organism to study disease. Like other animal models, Danio rerio colonies are
at risk of pathogenic infection. Microsporidia, a group of intracellular fungus-like parasites, are one potential
threat. Microsporidian spores germinate and spread causing pathological changes in the central nervous system,
skeletal muscle, and other...

We provide the first evidence on the causal effect of border enforcement on the
full spatial distribution of Mexican immigrants to the United States. We address the
endogeneity of border enforcement with an instrumental variables strategy based on
administrative delays in budgetary allocations for border security. We find that 1,000...
