Genetic Diversity of Snow Leopards Snow leopards (Panthera uncia) are endemic to the Altai, Himalaya, and Tibetan uplifts and adapted to high-altitude environments.  They are currently listed as an endangered species by IUCN.  This new paper investigated genetic diversity of snow leopards across their range.  They found that the cats have low genetic diversity in…

Plants in a Prickle? Not When Carnivores are Near. Herbivores’ risk-avoidance behavior from predators and plants’ anti-herbivore defenses appear to interact to determine the distribution of trees in African savannas. Thorny trees were found to be abundant in low-risk areas for herbivores while poorly defended trees were more abundant in high-risk areas. Therefore, plants can…

Two salamander species, one habitat, vastly different population structure Salamanders with similar ecological characteristics have different genetic structure in the same landscape. Highlights that similar species might respond differently to habitat change because of small life history differences. Watch out NYC rats, there’s a new predator in town! First time a fisher (Martes pennanti) is…

Human-mediated change in population structure of ragweed This article (subscription) characterizes the genetic structure of contemporary and historical (from herbarium samples) ragweed. They find that population structure has changed in response to human influence on the landscape. Penguin chick survival This article (OA) estimates Magellanic penguin chick survival over 27 years. They observed that storm…
