Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity

Journal of Animal Ecology, EarlyView.
Fishing is not allowed within wind farms; therefore, discard‐feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black‐backed Gulls avoided the wind farm area, but not each individual in each period. Avoidance of the wind farm was not driven by fishing exclusion within its perimeter.

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

Journal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

An intuitive method to calculate the utilization distribution of an animal from step‐selection analysis

Methods in Ecology and Evolution, EarlyView.
Abstract Step‐selection analysis (SSA) is a popular tool for estimating resource/habitat selection conditional on the local availability of conditions as determined by an animal's movement capacity. These models can be subsequently used to parameterize a movement model; however, most SSAs focus instead merely on interpreting the direction and magnitude

Tuning the tools: Validating empirical and modelled correction factors for diet estimation in pelagic teleosts

Methods in Ecology and Evolution, EarlyView.
Abstract As quantitative diet estimates from biochemical markers grow in popularity, the necessity for robust species‐ and tissue‐specific correction factors, including trophic discrimination factors (TDFs) for stable isotopes and calibration coefficients (CCs) for fatty acids, becomes increasingly urgent.

Addressing Bias in Non‐Probability Fisheries Surveys Using Multilevel Regression and Poststratification Approaches

Fish and Fisheries, EarlyView.
ABSTRACT Quantifying harvest of fish stocks is challenging as census data are often unavailable, so surveys are required. Traditional probability‐based surveys use random sampling to obtain representative data that can be scaled to estimate total impact.

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing
