Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Both forest cover and land management practices explain variation in recovering pine marten densities

Wildlife Biology, EarlyView.
Robust monitoring of wildlife populations to guide interventions is fundamental to conservation and wildlife management. Understanding how landscape characteristics are influencing predator population dynamics is often vital to inform recovery strategies, management, and policy. The pine marten Martes martes is recovering in the UK; however, population

Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

Wildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Seed dormancy explains plant response to mass mortality events

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mass mortality events (MMEs) are large‐scale, rapid die‐offs resulting in extreme inputs of carrion biomass. Recent work demonstrates the effects of increasing carrion biomass on plant communities modulated by vertebrate scavengers and herbivores.

Parental care and bird embryonic metabolism: A comparison between uniparentally incubating Silver‐throated Tits and biparentally incubating Black‐throated Tits

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

Elevation reverses the effects of forest structure on folivory and leaf asymmetry

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Centuries of timber production have homogenized many forests by reducing variation in canopy density and deadwood availability, with far‐reaching consequences for biodiversity and trophic interactions.
