Use of restored riparian habitat by the endangered least Bell's vireo (Vireo bellii pusillus) Use of restored riparian habitat by the endangered least Bell's vireo (Vireo bellii pusillus)
A primary objective of riparian restoration in California is the creation of habitat for endangered species. Four restoration sites in San Diego County were monitored between 1989 and 1993 and evaluated for their suitability as nesting habitat for Vireo bellii pusillus (Least Bell's Vireo), a state and federally endangered obligate riparian breeder. Vegetation structure at each site was...

Metal and trace element burdens in two shorebird species at two sympatric wintering sites in southern California Metal and trace element burdens in two shorebird species at two sympatric wintering sites in southern California
In January and November, 1994, ten willets (Catoptrophorus semipalmatus) and ten black-bellied plovers (Pluvialis squatarola) were collected at a south-facing sandy beach at the North Island Naval Air Station (NASNI) and ten willets and three plovers were collected at the Tijuana Slough National Wildlife Refuge (TSNWR), 16 km to the southeast. Concentrations of 19 inorganic analytes were

Trace element concentrations in two subpopulations of lesser snow geese from Wrangel Island, Russia Trace element concentrations in two subpopulations of lesser snow geese from Wrangel Island, Russia
Lesser snow geese (Anser c. caerulescens) from the Wrangel Island, Russia breeding colony spend the winter in two widely separated areas: the northern subpopulation in southern British Columbia and northern Washington and the southern subpopulation in the Central Valley of California. We examined 19 trace elements in the eggs and livers of geese from these two subpopulations to examine...

Mechanism of smoke-induced seed germination in a post-fire chaparral annual Mechanism of smoke-induced seed germination in a post-fire chaparral annual
1 Smoke-stimulated germination in the post-fire flora of California chaparral does not appear to be triggered by nitrate. Application of freshly prepared unbuffered KNO3 solutions (pH c. 6.2) failed to enhance germination of five populations of Emmenanthe penduliflora or one Phacelia grandiflora population, regardless of light or stratification conditions. 2 KNO3 buffered at acidic pH...

Pathology of diseases in wild desert tortoises from California Pathology of diseases in wild desert tortoises from California
Twenty-four ill or dead desert tortoises (Gopherus agassizii) were received between March 1992 and July 1995 for necropsies from the Mojave and Colorado deserts of California (USA). Diseases observed in these animals included cutaneous dyskeratosis (n = 7); shell necrosis (n = 2); respiratory diseases (n = 7); urolithiasis (n = 3); and trauma (n = 5). In tortoises with cutaneous...
