Desert Tortoise (Gopherus agassizii) Desert Tortoise (Gopherus agassizii)

The desert tortoise is widely distributed throughout major portions of the Mojave and Sonoran deserts of California, Nevada, Utah, Arizona, Sonora, and Sinaloa. Genetic, morphological, ecological, and behavioral features suggest an evolutionary divergence between the tortoises found south and east of the Colorado River (“Sonoran population”), and those found north and west of the river (...

Interspecific interactions in trematode communities Interspecific interactions in trematode communities

This chapter reviews the behavioural ecology of trematodes, focusing on intramolluscular stages. Interspecific competitive interactions, their frequency, dominance hierarchies and resolutions are discussed. Strategies employed by larval trematode species to adapt to a hostile, competitive environment, how these adaptations shape larval trematode communities, and how altered trematode...

Management and conservation of San Francisco Bay salt ponds: effects of pond salinity, area, tide, and season on Pacific Flyway waterbirds Management and conservation of San Francisco Bay salt ponds: effects of pond salinity, area, tide, and season on Pacific Flyway waterbirds

Throughout the world, coastal salt ponds provide habitat for large numbers and diversities of water- birds. San Francisco Bay contains the most important coastal salt pond complexes for waterbirds in the United States, supporting more than a million waterbirds through the year. As an initial step in attempting to understand how the anticipated conversion of salt ponds to tidal marsh...
