Recolonizing gray wolves increase parasite infection risk in their prey. [PDF]

open access: yesEcol Evol, 2018
AbstractThe recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate

Gray wolf harvest in Idaho

open access: yesWildlife Society Bulletin, 2016
Regulated harvest is a relatively new phenomenon for gray wolves (Canis lupus) in the contiguous United States. Most studies of wolf harvest have been conducted in northern latitudes where wolf populations are large and human densities are low.

Estimating biomass of berries consumed by gray wolves

open access: yesWildlife Society Bulletin, 2017
Gray wolves (Canis lupus) consume berries and other wild fruits seasonally when available or abundant. However, a method to convert percent frequency of occurrence or percent volume of berries in wolf scats to percent biomass has not yet been developed ...

Natural Selection and Origin of a Melanistic Allele in North American Gray Wolves. [PDF]

open access: yesMol Biol Evol, 2018
Pigmentation is often used to understand how natural selection affects genetic variation in wild populations since it can have a simple genetic basis, and can affect a variety of fitness-related traits (e.g., camouflage, thermoregulation, and sexual display).

Considering Pleistocene North American wolves and coyotes in the eastern Canis origin story

open access: yesEcology and Evolution, 2021
The evolutionary origins and hybridization patterns of Canis species in North America have been hotly debated for the past 30 years. Disentangling ancestry and timing of hybridization in Great Lakes wolves, eastern Canadian wolves, red wolves, and ...

PID Control Model Based on Back Propagation Neural Network Optimized by Adversarial Learning-Based Grey Wolf Optimization

open access: yesApplied Sciences, 2023
In processes of industrial production, the online adaptive tuning method of proportional-integral-differential (PID) parameters using a neural network is found to be more appropriate than a conventional controller with PID for controlling different ...

EPAS1 variants in high altitude Tibetan wolves were selectively introgressed into highland dogs [PDF]

open access: yesPeerJ, 2017
Background Admixture can facilitate adaptation. For example, black wolves have obtained the variant causing black coat color through past hybridization with domestic dogs and have higher fitness than gray colored wolves.

Similar behavioral but different endocrine responses to conspecific interactions in hand-raised wolves and dogs

open access: yesiScience, 2023
Summary: Domestication has altered dogs’ conspecific social organization compared to their closest, non-domesticated relatives, gray wolves. Wolves live in packs whose survival depends on coordinated behavior, but dogs rely less on conspecifics, which ...
