Habitat suitability and demography, a time‐dependent relationship
The habitat suitability index, which reflects spatial variability in species occurrence probability, has been shown to exhibit various contrasting relationships with local demographic performances (survival, productivity) in several species. One proposed explanation for these discrepancies is that the link between the habitat suitability index and demography is influenced by density-dependent, ...
متن کاملUncertainty in Various Habitat Suitability Models and Its Impact on Habitat Suitability Estimates for Fish
Species distribution models (SDMs) are extensively used to project habitat suitability of species in stream ecological studies. Owing to complex sources of uncertainty, such models may yield projections with varying degrees of uncertainty. To better understand projected spatial distributions and the variability between habitat suitability projections, this study uses five SDMs that are based on...

Arlt, D. 2007. Habitat selection: Demography and Individual Decisions. Doctor’s dissertation. ISSN 1652-6880, ISBN 978-91-576-7316-9 Habitat selection is the behavioural process determining the distribution of individuals among habitats varying in quality, thus affecting individual fitness and population growth. Models of population dynamics often assume that individuals have perfect knowledge ...
متن کاملHabitat suitability modelling and niche theory
1. The concept of the ecological niche relates a set of environmental variables to the fitness of species, while habitat suitability models (HSMs) relate environmental variables to the likelihood of occurrence of the species. In spite of this relationship, the concepts are weakly linked in the literature, and there is a strong need for better integration. 2. We selectively reviewed the literatu...
متن کاملRelationship between Hydromorphological and Ecohydraulic Characteristics Flow Regime to Habitat Suitability Capoeta gracilis (Keyserling, 1861): Understanding Habitat–Population Dynamics Fishes and Ecological Flow Scenarios of Zarrin-Gol River
Investigation of ecological, hydrological status and habitat Suitability of river is one of the key elements in river ecosystem management. In this regard, in the present study, in order to evaluate the ecological sustainable conditions in Zarrin-Gol River of Golestan Province, during stepwise calculations, echo-hydraulic and hydromorphocological analysis of the habitat of Capoeta gracilis (Ke...
