Seed germination patterns of Salvia mellifera in fire-prone environments Seed germination patterns of Salvia mellifera in fire-prone environments
Salvia mellifera seeds from coastal sage, chaparral and desert scrub in southern California failed to germinate in the dark unless exposed to powdered charred wood. This pattern was observed for seeds given a one month stratification at 5 C and for ones not stratified and also for seeds incubated under continuous 23 C or a diurnal alternation of 13 C/23 C. Dark inhibition of germination...

Status of a translocated sea otter population and its habitat in Washington Status of a translocated sea otter population and its habitat in Washington
During the summers of 1969 and 1970, the Alaska Department of Fish and Game and the Washington Department of Game translocated 59 sea otters from Amchitka Island, Alaska, to release sites in Washington (Jameson et al. 1982, Wildl. Soc. Bull. 10:100-107). Of the 29 released near Pt. Grenvil (Fig. 1) in 1969, 16 are known to have died. In 1970, 30 otters were held in a floating enclosure...

Activity-time budgets of sea otters in California Activity-time budgets of sea otters in California
Daily time budgets and activity patterns of sea otters (Enhydra lutris) were determined by scan sampling at 4 study areas in central California. Diet was determined by direct observation of foraging animals. Average time invested in foraging ranged from 11 to 71% among viewing areas (1-2 km of coastline) and from 21 to 28% among study areas (8-10 km of coastline). Foraging time budgets...

Demographic patterns of the shrub Ceanothus megacarpus in an old stand of chaparral in the Santa Monica Mountains Demographic patterns of the shrub Ceanothus megacarpus in an old stand of chaparral in the Santa Monica Mountains
Wildfires have had a major influence on the structural and functional adaptations that have evolved in Mediterranean-type ecosystems. Some chaparral shrubs sprout after fires while others produce serotinous cones or seeds refractory to germination until they are cued by a fire. Ceanothus megacarpus is a sclerophylous shrub commonly found in California in either pure of mixed stands which...
