A comparison of ultrasonic detectors and radiotelemetry for studying bat–habitat relationships

open access: yesWildlife Society Bulletin, 2011
Ultrasonic bat detectors and radiotelemetry are 2 methods used to examine habitat selection for bats, but no one has empirically examined if conclusions drawn from these 2 methods are comparable and, although previous work has presented concerns ...

Propagule limitation, disparate habitat quality, and variation in phenotypic selection at a local species range boundary.

open access: yesPLoS ONE, 2014
Adaptation to novel conditions beyond current range boundaries requires the presence of suitable sites within dispersal range, but may be impeded when emigrants encounter poor habitat and sharply different selection pressures.

Integrating Livestock Grazing and Sympatric Takin to Evaluate the Habitat Suitability of Giant Panda in the Wanglang Nature Reserve

open access: yesAnimals, 2021
Habitat suitability provides essential information for the management of protected species. However, studies that jointly consider the impacts of human disturbance and sympatric animals in habitat suitability assessments of giant panda are limited, which

Combining Regional Habitat Selection Models for Large-Scale Prediction: Circumpolar Habitat Selection of Southern Ocean Humpback Whales

open access: yesRemote Sensing, 2021
Machine learning algorithms are often used to model and predict animal habitat selection—the relationships between animal occurrences and habitat characteristics.

Habitat selection in whiting [PDF]

open access: yesJournal 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

open access: yesFishes
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 [PDF]

open access: yes, 2007
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 about habitat qualities and settle accordingly in the best habitats available.

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

open access: yesEcology 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.

Scale-Dependent Habitat Selection and Size-Based Dominance in Adult Male American Alligators.

open access: yesPLoS ONE, 2016
Habitat selection is an active behavioral process that may vary across spatial and temporal scales. Animals choose an area of primary utilization (i.e., home range) then make decisions focused on resource needs within patches.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
