Sex, landscape diversity and primary productivity shape the seasonal space use of a migratory European raptor

Journal of Avian Biology, 2022
Intrinsic and extrinsic drivers shape the space use of wide‐ranging raptors. A large proportion of raptors are migrants that shift their activity ranges between summer and winter habitats, where they encounter different environmental conditions ...

Body condition and habitat use by Hermann's tortoises in burnt and intact habitats [PDF]

Conservation Physiology, 2014
In Mediterranean regions, fires threaten terrestrial tortoises. Nevertheless, varying proportions of adults survive fire; these surviving individuals can play a central role for population recovery. The regions devastated by fire often include important habitat of Hermann's tortoises (Testudo hermanni hermanni), so assessing the ability of survivors to

Multiple habitat associations: the role of offsite habitat in determining onsite avian species density [PDF]

, 2012
Many animal populations continue to decline despite occurring in protected areas or on sympathetically managed sites. Frequently, this is because a specific habitat patch may not fulfil all the niche requirements of a threatened species.

Habitat Selection and Risk of Predation: Re-colonization by Lynx had Limited Impact on Habitat Selection by Roe Deer [PDF]

, 2013
Risk of predation is an evolutionary force that affects behaviors of virtually all animals. In this study, we examined how habitat selection by roe deer was affected by risk of predation by Eurasian lynx - the main predator of roe deer in Scandinavia ...

A General Approach for the Analysis of Habitat Selection [PDF]

, 2007
Investigating habitat selection of animals aims at the detection of preferred and avoided habitat types as well as at the identification of covariates influencing the choice of certain habitat types.

Specialization in habitat use by coral reef damselfishes and their susceptibility to habitat loss [PDF]

Ecology and Evolution, 2012
AbstractWhile it is generally assumed that specialist species are more vulnerable to disturbance compared with generalist counterparts, this has rarely been tested in coastal marine ecosystems, which are increasingly subject to a wide range of natural and anthropogenic disturbances. Habitat specialists are expected to be more vulnerable to habitat loss

Linking habitat use to range expansion rates in fragmented landscapes: a metapopulation approach [PDF]

, 2010
Temperature increases because of climate change are expected to cause expansions at the high latitude margins of species distributions, but, in practice, fragmented landscapes act as barriers to colonization for most species.
