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:

KCRL welcomes visiting scholar Calebe Pereira Mendes

The KCRL is very pleased to welcome Calebe Pereira Mendes from Universidade Estadual Paulista, São Paulo, Brazil.  Calebe is a PhD student interested in understanding how environmental factors moderate the behavioral ecology of mammals and how animal movements affect plant-animal interactions.  As part of his PhD program, Calebe is required to complete research for one of his dissertation chapters abroad.  We are delighted that he chose to do his research with us at the University of Arizona! Here’s to many new adventures Calebe and welcome aboard!

KCRL doctoral student Sarah Hale receives travel grant from the American Society of Mammalogists

Congratulations to KCRL doctoral candidate, Sarah Hale, on receipt of a competitive travel grant from the American Society of Mammalogists! Sarah will travel to Jacksonville, Florida this June to present her work in a talk entitled “The potential role of a native grazer and keystone species in managing woody encroachment” that represents a portion of her dissertation work on the impacts of reintroduced black-tailed prairie dogs on grassland ecosystems.  Learn more about Sarah at: https://snre.arizona.edu/people/sarah-hale and her research at: http://ag.arizona.edu/research/redsquirrel/students/shale.html
