Japanese wolves are most closely related to dogs and share DNA with East Eurasian dogs

Nature Communications
Although the domestic dog’s origin is still unclear, this lineage is believed to have been domesticated from an extinct population of gray wolves, which is expected to be more closely related to dogs than to other populations of gray wolves.

Molecular and Evolutionary History of Melanism in North American Gray Wolves [PDF]

Science, 2009
Morphological diversity within closely related species is an essential aspect of evolution and adaptation. Mutations in the Melanocortin 1 receptor ( Mc1r ) gene contribute to pigmentary diversity in natural populations of fish, birds, and many mammals.

Sustainability Strategies in the Cocoa‐Chocolate Value Chain: An Analysis Using Stakeholder Theory, Global Value Chain Theory, and Resource Dependence Theory

Agribusiness, EarlyView.
ABSTRACT The cocoa‐chocolate value chain faces significant environmental and social challenges, driving firms to adopt sustainability strategies ranging from individual practices to third‐party certifications. This study investigates the factors associated with these strategies by analyzing 304 cocoa‐chocolate companies using firm‐level data from the ...

Comparative Neuromechanical Wing‐Actuation Architectures of Flapping Flight in Insects, Hummingbirds, and Robots

Advanced Intelligent Systems, EarlyView.
Natural fliers achieve remarkable aerial performance through diverse wing neuromechanical systems integrating actuation, sensing, and control. This study synthesizes neuromechanical architectures in insects and hummingbirds, identifying two key functional types‐Dual Neural‐Mechanical Oscillator and Neurally‐modulated Mechanical Oscillator‐ and ...

Sarcoptic mange severity is associated with reduced genomic variation and evidence of selection in Yellowstone National Park wolves (Canis lupus)

Evolutionary Applications, 2021
Population genetic theory posits that molecular variation buffers against disease risk. Although this “monoculture effect” is well supported in agricultural settings, its applicability to wildlife populations remains in question. In the present study, we

Management of wolf and lynx conflicts with human interests [PDF]

, 2007
In many areas viable populations of large carnivores are political goals. One of the most important factors in order to achieve viable large carnivore populations is human tolerance for presence of large carnivores.

Estimating demographic parameters using a combination of known-fate and open N-mixture models

, 2015
1. Accurate estimates of demographic parameters are required to infer appropriate ecological relationships and inform management actions. Recently developed N-mixture models use count data from unmarked individuals to estimate demographic parameters, but

Fences can support restoration of human-dominated ecosystems when rewilding with large predators [PDF]

, 2018
The use of fences in conservation can be controversial, as artificial barriers constrain natural behaviour and ecological dynamics. However, in the case of large predators inhabiting protected areas within a hostile human-dominated landscape, predators ...

Disparity of turbinal bones in placental mammals

The Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Dining with wolves: Are the rewards worth the risks?

PLoS ONE
Where wild populations of gray wolves (Canis lupus) occur in North America, common ravens (Corvus corax) and, in western regions, black-billed magpies (Pica hudsonia) (Family Corvidae), show up quickly at wolf kills and scavenge carcasses, often feeding ...
