Continuously recording body temperature in terrestrial chelonians Continuously recording body temperature in terrestrial chelonians
The degree of interaction between mercury and cholinesterase inhibiting pesticides was determined by comparing enzyme responses to sublethal dosages of parathion or carbofuran in quail fed 0.05, 0.5, or 5.0 ppm morsodren for 18 weeks. A statistically significant interaction was defined as greater brain cholinesterase inhibition in morsodren-fed than in clean-fed birds following pesticide...

The use of geographic information for fire management planning in Yosemite National Park The use of geographic information for fire management planning in Yosemite National Park
Fire has played a critical role in the ecosystems of Yosemite National park for millennia. Before the advent of Euro-Americans, lightning fires and fires set by Native Americans burned freely across the landscape. These fires burned periodically, with the interval between fires dependent on the availability of ignition sources, adequate fuels, and weather conducive to burning. As a...

Pesticides and amphibian population declines in California, USA Pesticides and amphibian population declines in California, USA
Several species of anuran amphibians have undergone drastic population declines in the western United States over the last 10 to 15 years. In California, the most severe declines are in the Sierra Mountains east of the Central Valley and downwind of the intensely agricultural San Joaquin Valley. In contrast, coastal and more northern populations across from the less agrarian Sacramento...

Leaf conductance decreased under free-air CO2 enrichment (FACE) for three perennials in the Nevada desert Leaf conductance decreased under free-air CO2 enrichment (FACE) for three perennials in the Nevada desert
A common response of plants to elevated atmospheric CO2 concentration (CO2) is decreased leaf conductance. Consequently, leaf temperature is predicted to increase under elevated CO2. Diurnal patterns of leaf conductance and temperature were measured for three desert perennials, the C3 shrub Larrea tridentata, C3 tussock grass Achnatherum hymenoides and C4 tussock grass Pleuraphis rigida...

Sex differences in territorial behavior exhibited by the spotted hyena (Hyaenidae, Crocuta crocuta) Sex differences in territorial behavior exhibited by the spotted hyena (Hyaenidae, Crocuta crocuta)
Spotted hyenas (Crocuta crocuta) are gregarious carnivores that defend group territories against encroachment by neighboring conspecifics. Here we monitored the behavior of members of one clan of free-ranging spotted hyenas during border patrols, ‘wars’ with neighboring clans, and other interactions with alien intruders, to document differences between the sexes in territorial behavior...

Mapping wildland fuels for fire management across multiple scales: integrating remote sensing, GIS, and biophysical modeling Mapping wildland fuels for fire management across multiple scales: integrating remote sensing, GIS, and biophysical modeling
Fuel maps are essential for computing spatial fire hazard and risk and simulating fire growth and intensity across a landscape. However, fuel mapping is an extremely difficult and complex process requiring expertise in remotely sensed image classification, fire behavior, fuels modeling, ecology, and geographical information systems (GIS). This paper first presents the challenges of...
