Composition of Pteryxia terebinthina var. californica (Coult. and Rose) Mathias essential oils Composition of Pteryxia terebinthina var. californica (Coult. and Rose) Mathias essential oils
β-Pinene (35.0%, 53.8%) was the major component of both the aerial parts and the root oils of Pteryxia terebinthina var. californica, respectively. β-Phellandrene (12.2%) was the other most abundant component of the oil from aeial parts while δ-3-carene (14.2%) was the second abundant component of the root oil.

Status of translocated sea otters at San Nicolas Island, California Status of translocated sea otters at San Nicolas Island, California
In the 1970s about 1,650 southern sea otters (Enhydra lutris nereis) were restricted to the central California coast (Riedman and Estes, 1990), and a high volume of oil was being shipped through the region. Because of the vulnerability of sea otters to contamination from oil (Costa and Kooyman, 1982; Williams and Davis, 1995) that would likely spread wide- ly along the shore after a...

Pepperweed: a growing threat to western wildlife habitat Pepperweed: a growing threat to western wildlife habitat
Counts on photographs and visual estimates of the numbers of territorial gulls are usually reliable indicators of the number of gull nests, but single visual estimates are not adequate to measure the number of nests in individual colonies. To properly interpret gull counts requires that several islands with known numbers of nests be photographed to establish the ratio of gulls to nests...

Predation on Corynorhinus townsendii by Rattus rattus Predation on Corynorhinus townsendii by Rattus rattus
Corynorhinus townsendii (Townsend's big- eared bat) is a rare and declining species. Ex- tensive surveys for the coastal subspecies, C. t. townsendii, in California indicate that only 50% of historic maternity colonies are occu- pied currently (Pierson and Rainey, 1996). Three of the largest maternity colonies occur in Marin Co. Two of these have been moni- tored with evening exit counts...

Competition between alien annual grasses and native annual plants in the Mojave Desert Competition between alien annual grasses and native annual plants in the Mojave Desert
Alien annual grasses in the genera Bromus and Schismus are widespread and abundant in the Mojave Desert, and negative correlations between these aliens and native annual plants suggest that competition may occur between them. Effects of competition were evaluated by thinning alien annual grass seedlings and measuring the responses of native annual plants at three sites in the central...
