Poaching and habitat loss have reduced forest elephant populations in Central Africa by 63 percent since 2001. This widespread killing poses dire consequences not only for the species itself but also for the region’s forests, a new Duke University study finds.

During the nighttime, it is hotter in the city than in nearby suburbs or the countryside. But just how much hotter differs between cities. Researchers from the MSE2 (CNRS / MIT) international joint research laboratory and the Centre Interdisciplinaire des Nanosciences de Marseille (CNRS / Aix-Marseille University)1 have shown that the determining factor is how cities are structured: more organized cities, like many in North America with straight and perpendicular streets, trap more heat. Conversely, cities that are less organized, like those founded long ago, shed heat easily. The team's findings, published in Physical Review Letters (March 9, 2018), suggest new directions to explore for optimal urban planning and energy management.

Researchers monitoring San Francisco Bay for algal toxins have found a surprising array of different toxins in the water and in mussels collected from the bay. Four different classes of toxins, including one produced in freshwater environments, occur regularly throughout the bay, according to a study led by UC Santa Cruz researchers and published March 10 in Harmful Algae.

A new study led by the University of Stirling highlights improvements in the way conflicts between wildlife conservation and farming are managed worldwide.

Human encroachment is the leading cause of death among Ontario’s at-risk birds of prey, according to a first-ever University of Guelph study.
