Monkeys Swimming Across Rivers Refine Questions About the Riverine Barrier Hypothesis.

The Riverine Barrier Hypothesis posits that species distributions are limited by large rivers acting as geographical barriers. Accordingly, large rivers have long been thought to be a major driver of the extensive speciation and high levels of biodiversity among platyrrhine primates in South and Central America. Direct observations of river crossings provide evidence that complements studies of genetic diversity that can together shed new light on this hypothesis.

The impacts of "growing our own": a pilot project to address health disparities by training health professionals to become certified diabetes educators in safety net practices.

Purpose: The purpose of the study was to examine the impact of incorporating certified diabetes educator trainees into medical practices on patient diabetes outcomes.

Methods: This was a mixed methods practice-based evaluation study undertaken in 2 primary care practices in high-poverty neighborhoods in Buffalo, New York. The evaluation entailed a physician-referred patient cohort with pre- and postanalysis of chart review data corresponding to the American Diabetes Association's diabetes indicators.
