Species area relationships in mediterranean-climate plant communities Species area relationships in mediterranean-climate plant communities
Aim To determine the best-fit model of species–area relationships for Mediterranean-type plant communities and evaluate how community structure affects these species–area models. Location Data were collected from California shrublands and woodlands and compared with literature reports for other Mediterranean-climate regions. Methods The number of species was recorded from 1, 100 and 1000...

Growth rate predicts mortality of Abies concolor in both burned and unburned stands Growth rate predicts mortality of Abies concolor in both burned and unburned stands
Tree mortality is often the result of both long-term and short-term stress. Growth rate, an indicator of long-term stress, is often used to estimate probability of death in unburned stands. In contrast, probability of death in burned stands is modeled as a function of short-term disturbance severity. We sought to narrow this conceptual gap by determining (i) whether growth rate, in...

Evolution of CAM and C4 carbon-concentrating mechanisms Evolution of CAM and C4 carbon-concentrating mechanisms
Mechanisms for concentrating carbon around the Rubisco enzyme, which drives the carbon-reducing steps in photosynthesis, are widespread in plants; in vascular plants they are known as crassulacean acid metabolism (CAM) and C4 photosynthesis. CAM is common in desert succulents, tropical epiphytes, and aquatic plants and is characterized by nighttime fixation of CO2. The proximal selective...

Desert tortoise (Gopherus agassizii) survival at two eastern Mojave Desert sites: Death by short-term drought? Desert tortoise (Gopherus agassizii) survival at two eastern Mojave Desert sites: Death by short-term drought?
Survival of adult Desert Tortoises (Gopherus agassizii) appears related to site-specific variation in precipitation and productivity of annual plants. We studied adult tortoise survival rates at two closely situated, but physiographically different, sites in the eastern Mojave Desert over a nine-year period (spring 1992 to spring 2001). Survival rates were initially derived from...

Marine reserve design for conservation and fisheries management: a case study from the California Channel Islands Marine reserve design for conservation and fisheries management: a case study from the California Channel Islands
Five races of cottontail rabbits belonging to three species occur in Virginia. One of them, the Mearns cottontail (Sylvilagus floridanus mearnsi), is reported here for the first time. It occurs in six southwestern counties of the state, while the eastern cottontail (S. f. mallurus) occurs in the remainder of the state with the exception of Smith and Fishermans islands off the eastern...
