Effects of backpack radiotags on female northern pintails wintering in California Effects of backpack radiotags on female northern pintails wintering in California
To test whether backpack radiotags impacted the wintering biology of northern pintails (Anas acuta), I attached spear-suture (SSU, n=82 in 1993) or harness (HAR, n=337 in 1991-1993) backpack radiotags to female Hatch-Year (HY) and After-Hatch-Year (AHY) pintails after their autumn arrival in California. I evaluated impacts of radiotags on 1) wintering population distribution; 2) flock...

Uta stansburiana and Elgaria multicarinata on the California Channel Islands: Natural dispersal or artificial introduction? Uta stansburiana and Elgaria multicarinata on the California Channel Islands: Natural dispersal or artificial introduction?
Uta stansburiana and Elgaria multicarinata occur on several California Channel Islands, and recent introduction of some populations has been suggested because of similarity in life-history traits and body size to mainland populations. We sequenced representatives of each species from mainland southern California and some of the islands on which they occur. For each species, cytochrome...

Altered behavior in spotted hyenas associated with increased human activity Altered behavior in spotted hyenas associated with increased human activity
To investigate how anthropogenic activity might affect large carnivores, we studied the behaviour of spotted hyenas (Crocuta crocuta) during two time periods. From 1996 to 1998, we documented the ecological correlates of space utilization patterns exhibited by adult female hyenas defending a territory at the edge of a wildlife reserve in Kenya. Hyenas preferred areas near dense...

Spatial use and habitat associations of Columbian white-tailed deer fawns in southwestern Oregon Spatial use and habitat associations of Columbian white-tailed deer fawns in southwestern Oregon
Fawns represent a critical life history stage in the dynamics of deer populations, yet little recent information is available on the ecology of neonatal Columbian white-tailed deer (CWTD), a geographically isolated and federally endangered sub-species. We described home ranges, areas of concentrated use, and habitat associations of CWTD fawns in southwestern Oregon during the summers of...

Historical fire regime in southern California Historical fire regime in southern California
The historical variability in fire regime is a conservative indicator of ecosystem sustainability. Understanding the natural role of fire in chaparral ecosystems is therefore necessary for effective fire management.

Effects of desert wildfires on desert tortoise (Gopherus agassizii) and other small vertebrates Effects of desert wildfires on desert tortoise (Gopherus agassizii) and other small vertebrates
We report the results of standardized surveys to determine the effects of wildfires on desert tortoises (Gopherus agassizii) and their habitats in the northeastern Mojave Desert and northeastern Sonoran Desert. Portions of 6 burned areas (118 to 1,750 ha) were examined for signs of mortality of vertebrates. Direct effects of fire in desert habitats included animal mortality and loss of...

Satellite telemetry and wildlife studies in India: Advantages, options and challenges Satellite telemetry and wildlife studies in India: Advantages, options and challenges
Greater spatial coverage, accuracy and non-invasiveness of satellite technology make it one of the best tools to track long-distance migrants, which is otherwise difficult using conventional radio telemetry. In this article, we review the evolution of satellite telemetry and its application. We provide examples of three recent studies in India that have demonstrated and created a...
