Structured decision making as a conceptual framework to identify thresholds for conservation and management Structured decision making as a conceptual framework to identify thresholds for conservation and management
Thresholds and their relevance to conservation have become a major topic of discussion in the ecological literature. Unfortunately, in many cases the lack of a clear conceptual framework for thinking about thresholds may have led to confusion in attempts to apply the concept of thresholds to conservation decisions. Here, we advocate a framework for thinking about thresholds in terms of a

Modeling species occurrence dynamics with multiple states and imperfect detection Modeling species occurrence dynamics with multiple states and imperfect detection
Recent extensions of occupancy modeling have focused not only on the distribution of species over space, but also on additional state variables (e.g., reproducing or not, with or without disease organisms, relative abundance categories) that provide extra information about occupied sites. These biologist-driven extensions are characterized by ambiguity in both species presence and...

Habitat-specific breeder survival of Florida Scrub-Jays: Inferences from multistate models Habitat-specific breeder survival of Florida Scrub-Jays: Inferences from multistate models
Quantifying habitat-specific survival and changes in habitat quality within disturbance-prone habitats is critical for understanding population dynamics and variation in fitness, and for managing degraded ecosystems. We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection...

Patterns and determinants of mammal species occurrence in India Patterns and determinants of mammal species occurrence in India
Many Indian mammals face range contraction and extinction, but assessments of their population status are hindered by the lack of reliable distribution data and range maps. 2. We estimated the current geographical ranges of 20 species of large mammals by applying occupancy models to data from country-wide expert. We modelled species in relation to ecological and social covariates...

North American Bird Banding and quantitative population ecology North American Bird Banding and quantitative population ecology
Early bird-banding programs in North America were developed to provide descriptions of bird migration and movement patterns. This initial interest in description quickly evolved into more quantitative interests in two ways. There was (1) interest in quantifying migration and movement patterns, and (2) rapid recognition that re-observations of marked birds provided information about other
