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...

Translocated sea otter populations off the coasts of Oregon and Washington Translocated sea otter populations off the coasts of Oregon and Washington
The historical distribution of sea otters extended from the northern islands of Japan north and east across the Aleutian chain to the mainland of North America then south along the west coast to central Baja California, Mexico (Riedman and Estes 1990). By the beginning of the twentieth century, after 150 years of being intensively hunted for their valuable fur, sea otters had been...

Actual evapotranspiration and deficit: Biologically meaningful correlates of vegetation distribution across spatial scales Actual evapotranspiration and deficit: Biologically meaningful correlates of vegetation distribution across spatial scales
Correlative approaches to understanding the climatic controls of vegetation distribution have exhibited at least two important weaknesses: they have been conceptually divorced across spatial scales, and their climatic parameters have not necessarily represented aspects of climate of broad physiological importance to plants. Using examples from the literature and from the Sierra Nevada of
