Spots All Over: Records of Piebaldism in Red‐Tailed Squirrel Syntheosciurus granatensis in Northwestern Ecuador

Ecology and Evolution
Pigmentation anomalies such as albinism, leucism, and melanism in mammals are uncommon but can provide insight into genetic, ecological, and demographic patterns within populations.

Citizen-Science Camera Trap Data Reveal Large-Scale Activity Patterns of the Bobcat (<i>Lynx rufus</i>) Across Mexican Ecosystems. [PDF]

Ecol Evol
We evaluated whether citizen science–derived camera‐trap records can be used to characterize large‐scale activity patterns of a widely distributed mesocarnivore across heterogeneous landscapes. Using 821 independent iNaturalist records, we quantified activity across six major vegetation types in Mexico with kernel density estimation, circular ...

Natives Against Invaders: Shared Use of Space and Temporal Segregation of Clouded Tiger-Cats (<i>Leopardus pardinoides</i>) and Domestic Dogs (<i>Canis familiaris</i>) in an Isolated Protected Area. [PDF]

Ecol Evol
We studied the spatial and temporal relationships between clouded tiger‐cats and dogs in an isolated protected area of Colombia. Dogs influenced the activity patterns of clouded tiger‐cats but not their habitat use. Conservation actions should be directed to mitigate potential contact between both species.

Land Use Effects on the Space Use and Dispersal of an Apex Predator in an Ecotone Between Tropical Biodiversity Hotspots

Diversity
Assessing the ranging and dispersal behavior of apex predators and its consequences for landscape connectivity is of paramount importance for understanding population and ecosystem effects of anthropogenic land use change. Here, we synthesize ranging and

Presence of Nationally Banned Carbamates and Organophosphate Pesticides in Wild Carnivores, Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.
