Dwarf forms of Pinus rigida inhabit a variety of environments where stress factors (nutrient deprivation, drought, wind, and salt spray) and fire disturbances are strong selection factors within the local biological community. Pinus rigida morphology in stressed and disturbed communities ranges from medium sized trees to dwarf and prostrate trees forms. I selected three communities where Pinus rigida exhibited stress adapted morphology including the...

I examined biodiversity management issues, implications and opportunities in a working industrial landscape of the San Bernardino Mountains, California, USA, where historic and active mining operations overlap habitat occupied by threatened, endangered or protected plant and animal tax. To elucidate patterns of habitat use by ungulates in a mini-influenced landscape, I evaluated resource selection by the Cushenbury population of desert bighorn sheep...

Introduces different plant ecosystems, including forests, grasslands, deserts, and tundra, and describes what life is like in the world's most extreme biomes.

Fisher In A Fragmented Forest is an adaptable classroom or field-based environmental education activity guide focused on providing students the opportunity to learn about forest ecology, natural history and stakeholder issues as framed by the issues and challenges facing the Pacific fisher in the southern Sierra Nevada. This guide provides educational programming for grades Kindergarten through high school that meet California Science Content Standards...

This book covers a wide array of plants, animals, and ecology-based terms from A to Z.

Introduces the animals that call the desert home, such as lizards and snakes.

Annual fish species found in the family Cyprinodontidae (killifishes, pupfishes, and tooth carps) inhabit isolated bodies of freshwater throughout North and South America and Africa that can experience seasonal drought and desiccation. Many of these species survive extinction by laying drought-resistant eggs which undergo several phases of reversible developmental arrests or diapause during their ontogeny. Desert pupfish (Cyprinodon macularius) are...

Riparian areas provide unique ecosystem functions that are essential to the heath of surrounding aquatic and terrestrial systems, yet many riparian areas are severely degraded or absent entirely. Within the Flathead River watershed in northwestern Montana, restoration efforts are currently underway to revegetate areas and improve the lost functions. Long-term survival of planted woody riparian species is dependent on finding ways to successfully protect...

Yellowstone National Park, the world's first public park, is the heart of an almost intact natural ecosystem. Not just a world-class tourist attraction, Yellowstone has become a premier teaching and learning ground in recreation, natural resources, and wilderness management. The Greater Yellowstone Ecosystem (GYE) is home to North America's largest free roaming herds of wild bison and elk, the largest concentrations of grizzly bear and gray wolf in...
