GOBUSH, K.S.*; WASSER, S.K.; University of Washington,Seattle: Patterns of Genetic Relatedness in a Poached Population of African Elephants Loxodonta africana Widespread poaching in the 1980�s potentially altered the demographic structure of matrilineal African elephant groups(Loxodonta africana)in many populations by decreasing the number of old, adult female kin (Barnes and Kapela, 1991, Poole, 1989). Using non-invasive […]

Identification of population structure for a rare and cryptic species implications for conservation
HAGERTY, B.E.*; TRACY, C.R.; University of Nevada, Reno; University of Nevada, Reno: Identification of population structure for a rare and cryptic species: implications for conservation The underlying spatial structure of populations within a species provides perspective for conservation planning. Direct methods are often used to estimate movements of individuals among populations and other ecological processes. […]
Factors Affecting Degree of Burrow Collapse and Resulting Tortoise Self Excavation and Behavior
BEAUMAN, R.L.*; MENDON�A, M.T.; Auburn University; Auburn University: Factors Affecting Degree of Burrow Collapse and Resulting Tortoise Self Excavation and Behavior The gopher tortoise is a federally listed species in the western portion of its range, and a species of concern elsewhere. Their burrows are often collapsed during human activity associated with logging activity and […]
Elusive species a novel approach to measuring activity and sampling availability
INMAN, Richard D.*; NUSSEAR, Kenneth E.; TRACY, C. Richard; Univ, Reno; USGS; Univ, Reno: Elusive species: a novel approach to measuring activity and sampling availability Many species present difficulties for studying behavior and/or abundance due to their elusiveness. Desert tortoises (Gopherus agassizii) are elusive because they remain underground in burrows for approximately 90% of the […]

Assessment of Brazilian Free-tailed Bat (Tadarida brasiliensis) Populations Using Advanced Infrared Thermal Imaging
HRISTOV, N.I.*; BETKE, M.; KUNZ, T.H.; Boston University; Boston University; Boston University: Assessment of Brazilian Free-tailed Bat (Tadarida brasiliensis) Populations Using Advanced Infrared Thermal Imaging The Brazilian free-tailed bat (Tadarida brasiliensis) is widespread in the southwestern United Stated between March and October, where it typically roosts in caves, buildings and bridges, forming some of the […]
Application of modeling activity and sampling availability toward improving monitoring of an elusive species
NUSSEAR, K. E.*; INMAN, R. D.; TRACY, C. R.; USGS Western Ecological Research Center; University of Nevada Reno; University of Nevada Reno: Application of modeling activity and sampling availability toward improving monitoring of an elusive species The USFWS is currently assessing the densities of desert tortoise using data from transects and Distance Sampling to calculate […]
Timing of birth affects body protein dynamics of mothers in an arctic mammal
Meeting Abstract 29.1 Jan. 5 Timing of birth affects body protein dynamics of mothers in an arctic mammal BARBOZA, P.S.*; PARKER, K.L.; Univ. of Alaska, Fairbanks; Univ. of Northern British Columbia ffpsb@uaf.edu Rapid changes in climate are altering the timing and abundance of food for seasonal reproduction in arctic animals. Reindeer and caribou typically form large herds […]
