South Coast bioregion South Coast bioregion
This chapter investigates the South Coast bioregion in Southern California. There are two broad ecological zones: the coastal valleys and foothill zone and the montane zone. Grasslands are resilient to a wide range of fire frequencies. Fire regimes in big-cone Douglas-fir forests vary spatially and temporally. Lodgepole pine forests are at the highest end of the elevational gradient for...

Evaluation of evidence supporting the effectiveness of desert tortoise recovery actions Evaluation of evidence supporting the effectiveness of desert tortoise recovery actions
As a federally threatened species, the desert tortoise's (Gopherus agassizii) recovery is required under the Endangered Species Act (ESA). According to the criteria established by the Desert Tortoise Recovery Plan (U.S. Fish and Wildlife Service 1994) for delisting the tortoise from ESA protection, the species as a whole will be considered recovered when tortoises have exhibited a...

Fire as a global ‘herbivore’: the ecology and evolution of flammable ecosystems Fire as a global ‘herbivore’: the ecology and evolution of flammable ecosystems
It is difficult to find references to fire in general textbooks on ecology, conservation biology or biogeography, in spite of the fact that large parts of the world burn on a regular basis, and that there is a considerable literature on the ecology of fire and its use for managing ecosystems. Fire has been burning ecosystems for hundreds of millions of years, helping to shape global...

Sexual differentiation in the distribution potential of northern jaguars (Panthera onca) Sexual differentiation in the distribution potential of northern jaguars (Panthera onca)
We estimated the potential geographic distribution of jaguars in the southwestern United States and northwestern Mexico by modeling the jaguar ecological niche from occurrence records. We modeled separately the distribution of males and females, assuming records of females probably represented established home ranges while male records likely included dispersal movements. The predicted

Bufo canorus Camp 1916, Yosemite Toad. Bufo canorus Camp 1916, Yosemite Toad.
Yosemite toads (Bufo canorus) are endemic to the Sierra Nevada, California, from Ebbetts Pass, Alpine County to the Spanish Mountain area, Fresno County (Karlstrom 1962, 1973; Stebbins 1966; unpublished Sierra National Forest survey data, 1995, 2002). Sites occur from 1,950–3,444 m elevation, with the majority of sites between 2,590–3,048 m (Karlstrom, 1962). Jennings and Hayes (1994a)
