Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Species traits mediate terrestrial mammal density responses to human impacts

open access: yesEcography, EarlyView.
Human activities are reshaping ecosystems, but their effects on species population density remain poorly understood. Most studies focus on species presence–absence, thus limiting insight into how anthropogenic pressures affect population density. Emerging evidence suggests that responses of natural populations to human disturbance are highly variable ...

Unveiling the significance of dog domestication in cognitive dysfunction: Are wolves protected?

open access: yesOpen Veterinary Journal
Over the course of their long coexistence with humans, dogs have developed a stronger bond with humans than with any other domestic species. This close relationship has promoted notable parallels in both genetics and lifestyle, thereby facilitating the ...

Death of Gray Wolves, Canis lupus, in Porcupine Erethizon dorsatum, Dens in Wisconsin [PDF]

open access: yes, 2003
Three Gray Wolves (Canis lupus) were found dead in porcupine (Erethizon dorsatum) dens in northern Wisconsin between 1996-2000. Use of these dens appeared to be cases of shelter-seeking behavior by wolves suffering from sarcoptic ...

Prognosis of acute symptomatic seizures and impact of prolonged treatment with anti‐seizure medication

open access: yesEpilepsia, EarlyView.
Abstract Objectives Acute symptomatic epileptic seizures (ASySs) occur in temporal proximity to acute brain insults. Given their low risk of subsequent unprovoked seizures, current guidelines recommend either no treatment with anti‐seizure medication (ASM) or early discontinuation, yet ASM treatment is often continued beyond hospital discharge.

Comparison of Activity Patterns for American Beavers, Gray Wolves, and Muskrats

open access: yes, 2021
American beavers (Castor canadensis) share the same niche as muskrats (Ondatra zibethicus) by creating lodges and they compete with one another when their vegetation needs overlap. Beavers face predation from gray wolves (Canis lupus).

Improved Power Tracking and Performance Evaluation Using a Tri‐Meta Hybrid DOA–CSA–WOA‐Based MPPT Controller for Standalone PV System

open access: yesEnergy Science &Engineering, EarlyView.
A Tri‐Meta Hybrid DOA–CSA–WOA Maximum Power Point Tracking controller is developed to enhance photovoltaic system performance. The proposed approach achieves higher tracking efficiency, faster convergence, and robust operation under dynamic irradiance and partial shading conditions.

Developing a new shock‐collar design for safe and efficient use on wild wolves

open access: yesWildlife Society Bulletin, 2013
Electronic training collars, or shock collars, have received relatively little application as a non‐lethal management tool for reducing livestock losses caused by gray wolves (Canis lupus).

Dogs, but Not Wolves, Lose Their Sensitivity Toward Novelty With Age

open access: yesFrontiers in Psychology, 2019
Selection of behavioral traits holds a prominent role in the domestication of animals, and domesticated species are generally assumed to express reduced fear and reactivity toward novel stimuli compared to their ancestral species.
