Spatial patterns in the abundance of the coastal horned lizard Spatial patterns in the abundance of the coastal horned lizard
Coastal horned lizards ( Phrynosoma coronatum) have undergone severe declines in southern California and are a candidate species for state and federal listing under the Endangered Species Act. Quantitative data on their habitat use, abundance, and distribution are lacking, however. We investigated the determinants of abundance for coastal horned lizards at multiple spatial scales...

Clam density and scaup feeding behavior in San Pablo Bay, California Clam density and scaup feeding behavior in San Pablo Bay, California
San Pablo Bay, in northern San Francisco Bay, California, is an important wintering area for Greater (Aythya marila) and Lesser Scaup (A. affinis). We investigated variation in foraging behavior of scaup among five sites in San Pablo Bay, and whether such variation was related to densities of their main potential prey, the clams Potamocorbula amurensis and Macoma balthica. Time-activity...

Avian furcula morphology may indicate relationships of flight requirements among birds Avian furcula morphology may indicate relationships of flight requirements among birds
This study examined furcula (wishbone) shape relative to flight requirements. The furculae from 53 museum specimens in eight orders were measured: 1) three-dimensional shape (SR) as indicated by the ratio of the direct distance between the synostosis interclavicularis and the ligamentous attachment of one of its clavicles to the actual length of the clavicle between those same two points...

Desert Tortoise (Gopherus agassizii) Desert Tortoise (Gopherus agassizii)
The desert tortoise is widely distributed throughout major portions of the Mojave and Sonoran deserts of California, Nevada, Utah, Arizona, Sonora, and Sinaloa. Genetic, morphological, ecological, and behavioral features suggest an evolutionary divergence between the tortoises found south and east of the Colorado River (“Sonoran population”), and those found north and west of the river (...
