New publication on antelope jackrabbit ecology!

KCRL master’s student Maria Altemus is co-author on a new paper on antelope jackrabbit ecology with David E. Brown, Randall Babb, and Consuelo Lorenzo.  This is a major contribution to one of the least studied hares in North America.

Brown, D. E., R. D. Babb, C. Lorenzo, and M. M. Altemus. 2014. Ecology of the antelope jackrabbit (Lepus alleni). The Southwestern Naturalist 59:575-587.

KCRL students present research at The American Society of Mammalogists 95th annual meeting

KCRL students Sarah Hale, Maria Altemus, and Melissa Merrick return from The American Society of Mammalogists 95th annual meeting in Jacksonville Florida after successfully presenting their research to an engaged, inquisitive audience.  Sarah, Maria, and Melissa’s presentations were well-received and great questions and discussion followed their presentations.  Sarah presented on the reintroduction of a keystone species, black-tailed prairie dogs, into southern Arizona grasslands, Maria presented the first observations of black-tailed jackrabbit seasonal space use and home range size, and Melissa presented an overview of her research on Mt. Graham red squirrel natal dispersal.

Excellent work and congrats all around!

KCRL attends the 7th International Colloquium on Arboreal Squirrels in Helsinki, Finland

KCRL director John Koprowski and members Allyssa Kilanowski, Jonathan Derbridge, Melissa Merrick, and alum Karen Munroe have returned from another successful and inspiring International Colloquium on Arboreal Squirrels hosted at the Finnish Museum of Natural History Helsinki, Finland.  This unique conference brings together individuals conducting research on tree squirrels from around the world and always inspires lasting friendships and collaboration.   Posters and presentations were excellent and we were treated to the sights in and around Helsinki, including observing Siberian flying squirrels (Pteromys volans) gliding through the forest in the dim twilight of midnight, exploring the Evo primeval old-growth forest, and observing Eurasian red squirrels (Sciurus vulgaris) followed by dinner with friends at Lammi Biological Station.  Many thanks to Ilpo Hanski, Vesa Solonen, and their amazing students for hosting this event! Check out an account of our adventures written by Varpu Pärssinen at the Finnish Museum of Natural History: http://www.luomus.fi/fi/tule-kaymaan/ajankohtaista/blogi/oravat-kiikarissa-mita-oravakonferenssissa-tapahtui

We are all looking forward to the 2018 Colloquium in Galway, Ireland!

New publication on Arizona gray squirrel survival and mortality

We invite you to check out a new publication by KCRL alum Nichole Cudworth MSc. on the survival and mortality of Arizona gray squirrels (Sciurus arizonensis) in the Huachuca Mountains of southern Arizona. Through her research and publication efforts, Nichole has single-handedly more than doubled what is currently known about this species, which is considered sensitive by the USDA Forest Service, Vulnerable in Arizona, and Threatened in Mexico.  Nichole’s contribution to mammalian research and conservation continues as she is now a biologist with the Wyoming Game and Fish Department where she is responsible for non-game mammal conservation projects in the state.  Way to go Nichole!

Tamiasciurus with middens and without – check out two great new publications from KCRL alums Erin Posthumus and Nicolas Ramos-Lara

We invite you to check out two excellent new publications from KCRL alums Erin Posthumus MSc and Nicolás Ramos-Lara PhD describing how red squirrel (Tamiasciurus hudsonicus grahamensis) larderhoards (middens) influence the abundance of other vertebrate species, and how the spacing behavior of non-larderhoarding Mearns’s squirrel (Tamiasciurus mearnsi) in dry conifer forests of Baja California, Mexico differs from that of their congeners.

Hsiang Ling Chen receives Outstanding Dissertation Award

We are delighted to announce that Dr. Hsiang Ling Chen, a very recent KCRL alum, was awarded the University of Arizona School of Natural Resources and the Environment’s Outstanding Dissertation Award at the department’s annual awards ceremony last week.  Hsiang Ling’s dissertation, “Barrier effects of roads and traffic on animal occurrence, space use, and movement” investigates the impact of fragmentation and traffic noise via an assessment of gap and road crossing through the use of the red squirrel (Tamiasciurus hudsonicus) as a model organism. The SNRE Outstanding Dissertation Award is given to doctoral students who have excelled in all phases of their degree program. This award recognizes both the student’s achievement and the advisor’s contribution.  Hsiang Ling has already begun her Post Doc in China so was not able to personally accept the award, but Dr. K was able to receive the award in her absence and we created a very memorable keepsake to remind her of this special event ;)  Way to go Dr. Chen and Dr. K!

Hsiang Ling Chen is always with us!

KCRL Master’s student Kirsten Fulgham successfully defends her thesis!

Congratulations to KCRL’s Kirsten Fulgham who successfully defended her MS in Natural Sciences thesis yesterday! This program is designed for teachers to obtain a research MS degree while working a full-time teaching position! Already overworked and underpaid, teachers in the program get to work even harder:) Truly inspirational. Her thesis is titled: KANGAROO RAT FORAGING IN PROXIMITY TO A COLONY OF REINTRODUCED BLACK-TAILED PRAIRIE DOGS and examines the interaction of two potential keystone species. It was a great presentation and we all learned a lot!  Read a bit more about her work at:
