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 ...

Oligogenic inheritance in epilepsy: A systematic exome‐wide analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Genetic factors contribute to the majority of epilepsies, but the exact genetic cause remains unknown in most patients. Incomplete penetrance and variable expressivity are frequent, and recent studies showed a burden of deleterious variants in epilepsy genes, suggesting a role for oligogenic inheritance.

Spatial overlap of gray wolves and ungulate prey changes seasonally corresponding to prey migration

open access: yesMovement Ecology

Phylogenetic analysis of mitochondrial cox-1 gene region as a DNA barcode marker for the Gray wolf, Canis lupus in Mongolia

open access: yesProceedings of the Mongolian Academy of Sciences
The gray wolf (Canis lupus), locally known as saaral chono, is a widely distributed species across Europe, North America, and Asia, including Mongolia. Over the last 45 years, Mongolia’s gray wolf population has declined threefold, highlighting the need ...
