History and management of crown-fire ecosystems: A summary and response History and management of crown-fire ecosystems: A summary and response
Some ecosystems, such as yellow pine forests, have had a long history of frequent surface fires, but because of fire suppression policy, fires have been largely excluded from them during the last century (Covington 2000). Unnatural fuel accumulation in these forests has increased the potential for large, catastrophic crown fires, and re-introduction of prescribed fire is one remedy for...

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...

Varied ecosystems need different fire protection Varied ecosystems need different fire protection
Covington states in his Commentary1 that the open ponderosa pine forests of the western United States are "in widespread collapse" because fire suppression by humans has eliminated the low-intensity surface fire regime that maintained the open, park-like structure of these forests. He fears this will lead to an "unprecedented" crown fire regime that will eliminate forests.

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 C4tussock grass Pleuraphis rigida...

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...

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...

Contaminant profiles of two species of shorebirds foraging together at two neighboring sites in south San Francisco Bay, California Contaminant profiles of two species of shorebirds foraging together at two neighboring sites in south San Francisco Bay, California
The San Francisco Bay estuary isused by over one million shorebirds during springmigration and is home to several hundred thousandduring the winter. Most shorebird use occurs in thesouthern reach of the estuary (South Bay). Thereduced water circulation and discharge fromindustrial sources in the South Bay are responsiblefor the highest levels of some trace elements in theestuary...
