KCRL grad students win big at the Arizona & New Mexico TWS Joint Annual Meeting

KCRL doctoral candidates Sarah Hale and Jonathan Derbridge swept the major student awards for the Arizona chapter of The Wildlife Society at the 2016 Arizona & New Mexico Joint Annual Meeting of The Wildlife Society and the American Fisheries Society in Flagstaff Arizona this week.

Sarah won the Best Student Presentation award and was selected from a pool of 6 excellent presentations from Master’s and PhD students.  This is an intense competition where students are required to submit their presentations and a write up of their research in advance of the meeting. The 6 top students are then selected from this pool and the winner is decided based on their presentation during a special session at the Joint Annual Meeting.  Way to go Sarah!!

Jonathan receive the Roger Hungerford Award for a top student in wildlife research who, while attending an Arizona college or university, made significant contributions to the management and conservation of Arizona’s wildlife and/or habitat. Contributions are in the areas of wildlife research, education and training, management, conservation, or law enforcement. The Award is given in memory of one of Arizona’s finest research biologists, Roger Hungerford.  Nicely done Jonathan!!

Congrats all around – keep up the good work, we are all glowing with pride.

Abert’s and red squirrel landscape level habitat use: similarities and differences

A new publication from KCRL alum Sandy Doumas on landscape characteristics associated with Abert’s squirrel (Sciurus aberti) and red squirrel (Tamiasciurus hudsonicus) feeding sign in a mixed conifer forest in northern Arizona, where the two species naturally co-occur. This research demonstrates that, while differences in forest use occur between the species, both red and Abert’s squirrels use a variety of conifer vegetation types, information important for future management plans.  Congrats Sandy!

Invasive, edge-adapted species and native, forest-dependent species respond very differently to roads and traffic

KCRL alum Dr. Hsiang Ling Chen’s dissertation research documenting the behavioral responses of introduced Abert’s squirrels (Sciurus aberti) and native, endangered Mt. Graham red squirrels (Tamiasciurus hudsonicus grahamensis) was just published in PLoS ONE. This research demonstrates the importance of considering both behavior and ecology of a species when considering potential impacts of roads.  Congrats Dr. Chen!!!

Cypress domes are an important habitat component for Big Cypress fox squirrels

New collaborative research between Big Cypress National Preserve scientists and KCRL’s Dr. Koprowski and Melissa Merrick demonstrates large home ranges and intense selection for cypress dome forest in a unique fox squirrel subspecies inhabiting a mosaic of swamps, wet forest, and grassland in southern Florida.

Dr. Koprowski featured in Huffington Post article

Why do squirrels appear fatter than usual this winter?  People are reporting portly squirrels in the UK and parts of Canada and the US this winter, and mild temperatures may be allowing squirrels to really pack in the calories.  Our fearless leader, Dr. Koprowski, is interviewed for this piece as a “noted squirrel expert”!
