The use of aquatic environmental DNA (eDNA) to detect the presence of species depends on the seasonal activity of the species in the sampled habitat. eDNA may persist in sediments for longer than it does in water, and analysing sediment could potentially extend the seasonal window for species assessment. Using the great crested newt as a model, we compare how detection probability changes acros...

Marine predators will often perform diel and seasonal movements associated with specific habitats. In tropical areas, mesophotic coral reefs may be an important habitat type for many predators, but their use of these areas has rarely been investigated. We used results of acoustic telemetry and stable isotope analyses to investigate the diel and seasonal movements of Galapagos sharks Carcharhinu...

reserches show that relationship between human and residential places is based upo both emotional and identity structures. in other words, habitat place is not only the creator of a part of humanistic identity but also form a kind of sentimental and emotional bond that may result in tendency to maintain closeness to a specific place. therefor, formaton of emotional and identity relationship wit...

Predicting how marine mammal populations respond to habitat changes will be essential for developing conservation management strategies in the 21st century. Responses to previous environmental change may be informative in the development of predictive models. Here we describe the likely effects of the last ice age on grey seal population size and distribution. We use satellite telemetry data to...

Negative interactions between waterbirds and people are increasing. Waterbirds feeding on agricultural crops cause significant losses to farmers worldwide, but so far most research address these conflicts has been conducted migratory species in the temperate northern hemisphere. We investigated space use habitat selection of magpie goose (Anseranas semipalmata), a taxonomically distinct waterbi...

isfahan wild sheep ovis orientalis isphahanica is listed as vulnerable in the iucn red list of threatened species. adequate knowledge on habitat requirements and environmental factors determining the niche of a species is central to its conservation programmes. however, there is scarcity of data on habitat associations of this species in iran. a gis-based model, using presence-only data, was us...

Knowledge of species-specific fish biology, ecology, and habitat use is critical for informing science-based management. Yellow perch Perca flavescens are an ecologically recreationally important species. Yet, many north-temperate systems (e.g. inland lakes Wisconsin), little known about yellow seasonal ecology. We characterised spatial distribution, size–structure, condition between littoral p...

The restoration of riparian sites following aggregate extraction frequently aims to expand the wetland habitat, and enhance the wetland wildlife community. However, aggregate extraction sites, typically on river flood plains, are subject to unpredictable flooding along with climate variability and other factors beyond the control of local management that may be equally important in determining ...
