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...

Estimating the magnitude of decline of the Florida torreya (Torreya taxifolia Arn.) Estimating the magnitude of decline of the Florida torreya (Torreya taxifolia Arn.)
Torreya taxifolia is a coniferous tree that is endemic to the 35 km stretch of bluffs and ravines along the east side of the Apalachicola River in northern Florida and adjacent southern Georgia. This formerly locally abundant tree declined during the 1950s and 1960s as a result of disease and is currently on the US Endangered Species list. For sparsely distributed species it can often be...

Population persistence in Florida torreya: Comparing modeled projections of a declining coniferous tree Population persistence in Florida torreya: Comparing modeled projections of a declining coniferous tree
The Florida torreya ( Torreya taxifolia) is a coniferous tree endemic to a 35-km stretch of bluffs and ravines along the east side of the Apalachicola River in northern Florida and southern Georgia. This formerly locally abundant tree has declined as a result of disease during the 1950s and is on the U.S. endangered species list. With no seed production in the wild, this species is...

Linking biodiversity to ecosystem function: Implications for conservation ecology Linking biodiversity to ecosystem function: Implications for conservation ecology
We evaluate the empirical and theoretical support for the hypothesis that a large proportion of native species richness is required to maximize ecosystem stability and sustain function. This assessment is important for conservation strategies because sustenance of ecosystem functions has been used as an argument for the conservation of species. If ecosystem functions are sustained at...
