New publication: Roads are barriers to small mammal movements

KCRL alum Dr. Hsiang Ling Chen’s recent publication in Biological Conservation demonstrates that even low traffic, narrow roads can act as barriers to small mammal movements due to gap avoidance behavior.  Dr. Chen’s research has important implications for the conservation and management of forest dependent small mammal species faced with fragmentation and disturbance.

Congrats to KCRL’s Maria Altemus MSc

KCRL celebrates Maria Altemus and her successful defense of her Master’s thesis titled Antelope jackrabbit (Lepus alleni) spatial ecology, habitat characteristics, and overlap with the endangered Pima pineapple cactus (Coryphantha scheeri var. robustispina).  

Maria is the first to record movement data of antelope jackrabbits via radio-telemetry and her research fills a significant knowledge gap in the life history and ecology of this charismatic but little-studied lagomorph.  Join us in congratulating Maria for a job well done!

Dr. K talks squirrel repellants, squirrel abundance to close Squirrel Week 2016

Can you ever really get rid of squirrels?  Where have all my squirrels gone? Dr. K is the go to guy for answers to your squirrel questions! In his second Squirrel Week interview with the Washington Post, Dr. K talks about whether you can ever really deter squirrels, and what factors influence squirrel density and abundance. Read the full story here:

New publication on modeling invasion and management of non-native squirrels

A new publication by KCRL post-doctoral researcher Dr. Emily Goldstein outlines how Spatially Explicit Population Models can be used to model future range expansion of an invasive squirrel species (the Eastern gray squirrel; Sciurus carolinensis) and assess the efficacy of different management scenarios and biological control strategies including immunocontraceptive vaccines and culling.  This research outlines proactive management and control strategies that can be implemented to slow the spread of gray squirrel invasion in Ireland.

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.
