Energized fencing reduces risk of American black bear (Ursus americanus) damage to bird feeders in Minnesota

open access: yesWildlife Society Bulletin, EarlyView.
Energized fences were effective at reducing black bear damage to bird feeders. The fences were 100% effective in a good natural bear food year and 77% effective in a poor natural bear food year. When bears breached the fences, the cause was typically poor electrical grounding.

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

open access: yesWildlife Society Bulletin, EarlyView.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding

open access: yesWildlife Society Bulletin, EarlyView.
Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.

Feeding Management of African Rhinos (Ceratotherium simum, Diceros bicornis) in European Zoos

open access: yesZoo Biology, EarlyView.
The average estimated diets (in % dry matter) of white rhinos (C. simum) and black rhinos (D. bicornis) in European zoos differ in the proportion of (pelleted) compound feed and other non‐forage items. The reason for this difference is elusive but possibly related to creating more complicated diets for browsers. ABSTRACT White rhinos (WR, Ceratotherium

Separate and synergistic anti‐herbivore effects of non‐glandular trichomes and leaf chemistry in a desert plant

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant defence phenotypes commonly integrate physical and chemical traits that may act synergistically against herbivores, but empirical evidence for synergy as a defence strategy remains limited.
