The future of fire in California ecosystems The future of fire in California ecosystems
This chapter reviews the concepts developed in the book and challenges Californians to accept the fact that they live in fire-prone ecosystems. California’s variety of fire regimes are products of its wide diversity of vegetation, climate, topography, and ignitions. The role fire plays in an ecosystem is characterized by the fire regime attributes that describe the pattern of fire...

Habitat use and spatial structure of a barking frog (Eleutherodactylus augusti) population in southeastern Arizona Habitat use and spatial structure of a barking frog (Eleutherodactylus augusti) population in southeastern Arizona
Barking Frogs (Eleutherodactylus augusti) are the northernmost ranging member of the large tropical family Leptodactylidae. We investigated the ecology of this saxicolous species at the northern edge of its range in a canyon in southern Arizona. We captured 54 frogs on discontinuous rock outcrops; eight of nine females and 39 of 45 males were on limestone outcrops. The remaining frogs...

Fishing for lobsters indirectly increases epidemics in sea urchins Fishing for lobsters indirectly increases epidemics in sea urchins
Two ecological paradigms, the trophic cascade and the host-density threshold in disease, interact in the kelp-forest ecosystem to structure the community. To investigate what happens when a trophic cascade pushes a host population over a host-threshold density, I analyzed a 20-year data set of kelp forest communities at 16 sites in the region of the Channel Islands National Park...

Ecological impacts of wheat seeding after a Sierra Nevada wildfire Ecological impacts of wheat seeding after a Sierra Nevada wildfire
The Highway Fire burned 1680 ha of mixed ponderosa pine–oak–chaparral in the newly created Giant Sequoia National Monument and the adjacent Sequoia National Forest of Fresno County, California in August 2001. The USDA Forest Service Burned Area Emergency Rehabilitation (BAER) program recommended that portions of the burned forest be seeded with a non-persistent variety of wheat at a...

Species boundaries, phylogeography, and conservation genetics of the red-legged frog (Rana aurora/draytonii) complex Species boundaries, phylogeography, and conservation genetics of the red-legged frog (Rana aurora/draytonii) complex
The red-legged frog, Rana aurora, has been recognized as both a single, polytypic species and as two distinct species since its original description 150 years ago. It is currently recognized as one species with two geographically contiguous subspecies, aurora and draytonii; the latter is protected under the US Endangered Species Act. We present the results of a survey of 50 populations...

The role of fire and fire management in the invasion of nonnative plants The role of fire and fire management in the invasion of nonnative plants
Spacecraft imagery, especially from the National Atmospheric and Oceanic Administration's Improved TIROS (Television Infra-Red Observational Satellite) Operational Satellites, permits timely evaluations of snow and ice conditions encountered by arctic nesting geese. Imagery from the TIROS satellite for 5 wide]y scattered locations in arctic North America was obtained for three 3-day...

Comparison of AVIRIS and Landsat ETM+ detection capabilities for burn severity Comparison of AVIRIS and Landsat ETM+ detection capabilities for burn severity
Our study compares data on burn severity collected from multi-temporal Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) with similar data from the Enhanced Thematic Mapper Plus (ETM+) using the differenced Normalized Burn Ratio (dNBR). Two AVIRIS and ETM+ data acquisitions recorded surface conditions immediately before the Hoover Fire began to spread rapidly and again the...
