Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Predicting disease spread from host movement data: Chronic wasting disease in North America as a case study

Journal of Animal Ecology, EarlyView.
This paper estimates the rate of chronic wasting disease spread in multiple regions and compares these rates with model predictions based on deer movement data. Abstract Rare long‐distance movements can increase the spatial spread of invasive species and shifts in species ranges. For wildlife disease spread, however, seasonal migrations may only matter

Understanding natal emigration in group‐living carnivores

Journal of Animal Ecology, EarlyView.
Dispersal is a key ecological and evolutionary process, yet drivers of variation in emigration under human‐modified conditions remain understudied. Using a novel genetic approach applied to harvested grey wolves in Idaho, USA, we found that prey availability and population density shape natal emigration patterns in a cooperative breeder.

Indirect fractures in long bones resulting from gunshot trauma: Occurrence, characterization, and need for additional research

Journal of Forensic Sciences, EarlyView.
Abstract Indirect fractures from gunshot wounds can occur when a projectile impacts soft tissue without making direct contact with the bone. Existing biomechanical and clinical research suggests that indirect fractures result in lower levels of comminution, and that resultant fracture patterns can resemble those seen in blunt force trauma (e.g., wedge ...

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

Integrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape

Animal Conservation, EarlyView.
Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Evaluation of a portable glucometer for blood glucose measurement in juvenile green sea turtles (Chelonia mydas)

Australian Veterinary Journal, EarlyView.
Blood glucose is a key physiological indicator in sea turtles, but its measurement in field settings can be challenging. Portable point‐of‐care (POC) glucometers offer practicality, yet their agreement with reference laboratory methods has not been established for juvenile green sea turtles (Chelonia mydas) from the Southwestern Atlantic.
