Pesticides and amphibian declines in California, USA Pesticides and amphibian 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...

We still need Smokey Bear! We still need Smokey Bear!
It was gratifying to see articles in recent issues of Fire Management Today clarifying the role of Smokey Bear in wildland fire management strategies (Baily 1999; Brown 1999). These articles clearly spelled out Smokey’s importance in reducing unplanned human-ignited wildland fires and rightly criticized attempts to detract from Smokey’s campaign (Williams 1995; see also Vogl 1973).

Effect of land cover, habitat fragmentation and ant colonies on the distribution and abundance of shrews in southern California Effect of land cover, habitat fragmentation and ant colonies on the distribution and abundance of shrews in southern California
Because effects of habitat fragmentation and anthropogenic disturbance on native animals have been relatively little studied in arid areas and in insectivores, we investigated the roles of different land covers, habitat fragmentation and ant colonies on the distribution and abundance of shrews, Notiosorex crawfordi and Sorex ornatus, in southern California. Notiosorex crawfordi was the...

Organochlorine concentrations and eggshell thickness in failed eggs of the California Clapper rail from south San Francisco Bay Organochlorine concentrations and eggshell thickness in failed eggs of the California Clapper rail from south San Francisco Bay
In 1992 we collected 22 failed California Clapper Rail (Rallus longirostris obsoletus) eggs from four tidal marshes of south San Francisco Bay for organochlorine analysis and determination of eggshell thickness. Mean eggshell thickness of these eggs (262 microns) was not statistically distinguishable from that of pre-1932 museum eggs (271 microns). Total PCB concentrations in eggs ranged...
