Isotopic evidence for the consumption of Galliformes by the red fox (Vulpes vulpes) in rural southern England

open access: yesWildlife Biology, EarlyView.
Anthropogenic resource subsidies can drive mesopredator population growth, altering predator–prey dynamics. The red fox Vulpes vulpes is a generalist canid that can readily exploit such subsidies. In the UK, tens of millions of pheasants Phasianus colchicus and red‐legged partridges Alectoris rufa are released annually for sport shooting, potentially ...

Limited Effects of Temperature on Captive Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) Growth

open access: yesZoo Biology, EarlyView.
While higher temperatures are generally expected to increase amphibian growth, our experiments with captive‐reared Eastern Hellbenders found no evidence that growth increased at a rearing temperature of 21°C relative to 16°C. As Eastern Hellbender reintroduction efforts move forward, a focus on other conditions, such as density or diet, might be more ...

Effects of Density and Food Availability on the Growth of Captive‐Reared Eastern Hellbenders

open access: yesZoo Biology, EarlyView.
Our experiments demonstrate that food is the major factor limiting captive‐reared Hellbender growth and that increasing rearing density to the tested levels does not negatively impact growth. Implementing these changes may result in larger, more robust Hellbenders and increase the success of reintroduction programs.

The Greatest Show (Birds) on Earth: Public Presentations and Their Welfare Impacts on Zoo‐Housed Birds

open access: yesZoo Biology, EarlyView.
Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

Radiographic Screening of Wild and Semi‐Wild Cape Ground Squirrels (Geosciurus inauris) for the Presence of Peri‐Apical Masses Associated With Elodont Incisor Teeth

open access: yesZoo Biology, EarlyView.
Peri‐apical masses were absent in both wild and semi‐wild Cape ground squirrels, despite dietary differences and minor incisor trauma. These findings suggest such lesions are rare outside captivity and not induced by low‐fiber diets alone, adding to the literature on environmental and dietary risk factors in elodont tooth pathology.

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Prey group cohesion mediates the outcome of predator–prey interactions under artificial lighting

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highest rates of piscivorous predation in the field have been recorded during crepuscular light levels associated with sunrise and sunset or artificial lighting at night (ALAN).
