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 in whiting [PDF]

Journal of Fish Biology, 2004
Given a choice of habitats in a laboratory experiment, whiting Merlangius merlangus preferentially spent most time over sand, then gravel and least time over a habitat with emergent structures. The introduction of a predator stimulus increased the preference for the sand habitat for large whiting, whereas small whiting had an increased preference for ...

Habitat-Selecting Life History

Fishes
Adaptive life histories emerge through their environmentally dependent effects on fitness. Those effects are consequences of habitat quality and the density-dependent decisions that organisms make on habitat choice. Density dependence for ideal organisms

Habitat selection ratios.

, 2020
Selection ratios with 95% CI calculated for selection of macroalgal habitat (MA), and bare sediment habitat (Bare), by flexible-foraging and specialized-foraging shorebirds. Significant selection (*) when CI does not overlap one (vertical line). Local vs.

Habitat selection models help inform critical habitat identification for a wide-ranging migratory ungulate

Global Ecology and Conservation
Assessing seasonal habitat preferences is crucial to understand patterns of habitat use in highly mobile species. Such knowledge can also help identify habitat essential to the recovery of endangered populations.

Grizzly bear habitat selection is scale dependent [PDF]

, 2007
The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of ...

Avian fitness consequences match habitat selection at the nest‐site and landscape scale in agriculturally fragmented landscapes

Ecology and Evolution, 2019
Habitat selection theory suggests that when choosing breeding sites, animals should choose the best available habitat; however, studies show that individuals fail to choose habitats that maximize their fitness especially in drastically altered landscapes.

Ocelots in the moonlight: Influence of lunar phase on habitat selection and movement of two sympatric felids.

PLoS ONE, 2023
Various landscape and environmental factors influence animal movement and habitat selection. Lunar illumination affects nocturnal visual perception of many species and, consequently, may influence animal activity and habitat selection.

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...
