Birds at a Southern California beach: seasonality, habitat use and disturbance by human activity Birds at a Southern California beach: seasonality, habitat use and disturbance by human activity
Use of a Santa Barbara beach by people and birds varied in both time and space. There were 100 birds, 18 people and 2 dogs per kilometer. Bird density varied primarily with the season and tide while human activity varied most between weekend and weekday. Bird distributions along the beach were determined mainly by habitat type (particularly a lagoon and exposed rocky intertidal areas)...

Mourning dove productivity in California during 1992-95: Was it sufficient to balance mortality? Mourning dove productivity in California during 1992-95: Was it sufficient to balance mortality?
Mourning dove (Zenaida macroura) populations have declined steadily in the western United States since 1966. We investigated the role of recruitment in this long-term problem by studying nesting ecology of mourning doves from March to September 1992-95, in the northern Central Valley, California, USA. We studied nesting doves in blue oak woodlands (Quercus douglasii), willow-cottonwood...

On incorporating fire into our thinking about natural ecosystems: A response to Saha and Howe On incorporating fire into our thinking about natural ecosystems: A response to Saha and Howe
Ecologists long have had a fascination with fire impacts, although they have been slow to incorporate this ecological factor into serious thinking about the structure of communities and evolution of species (Bond and van Wilgen 1996). The remarks by Saha and Howe (2001, in this issue) illustrate some of the problems ecologists have in trying to apply fire to their thinking about natural

An estimation of carrying capacity for sea otters along the California coast An estimation of carrying capacity for sea otters along the California coast
Carrying capacity (K) for the California sea otter (Enhydra lutris nereis) was estimated as a product of the density of sea otters at equilibrium within a portion of their existing range and the total area of available habitat. Equilibrium densities were determined using the number of sea otters observed during spring surveys in 1994, 1995, and 1996 in each of three habitat types where...

Restoring fire to wilderness: Sequoia and Kings Canyon National Parks Restoring fire to wilderness: Sequoia and Kings Canyon National Parks
Sequoia and Kings Canyon National Parks, established in 1890, consist of 863,741 acres (349,551 ha) of Sierra Nevada foothills, mid-elevation conifer forest, and high-elevation alpine environment. The parks contain 36 giant sequoia (Sequoiadendron giganteum) groves, including the largest known tree, the General Sherman. Ninety-four percent of the parklands is in designated or proposed...

Integration of genotoxicity and population genetic analyses in kangaroo rats (Dipodomys merriami) exposed to radionuclide contamination at the Nevada Test Site, USA Integration of genotoxicity and population genetic analyses in kangaroo rats (Dipodomys merriami) exposed to radionuclide contamination at the Nevada Test Site, USA
We examined effects of radionuclide exposure at two atomic blast sites on kangaroo rats (Dipodomys merriami) at the Nevada Test Site, Nevada, USA, using genotoxicity and population genetic analyses. We assessed chromosome damage by micronucleus and flow cytometric assays and genetic variation by randomly amplified polymorphic DNA (RAPD) and mitochondrial DNA (mtDNA) analyses. The RAPD...
