Coloration in Argia damselflies of Central Mexico responds to changes in herbaceous vegetation La coloración de caballitos del diablo del género Argia responde a cambios en la cobertura de vegetación herbácea en el Centro de México

Insect Conservation and Diversity, EarlyView.
The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

Outer bounds: Forest edges emulate vertical strata as a habitat filter for butterfly assemblages

Insect Conservation and Diversity, EarlyView.
Species filtering converged between fragmentation and vertical strata based on functional traits and phylogenetic relatedness. The understory of continuous forests guarantees high taxonomic, phylogenetic, and functional diversity of butterfly assemblages.

From Genes to Shapes: Exploring Local Adaptation in Carpathian Ox‐Eye Daisies

Journal of Biogeography, EarlyView.
ABSTRACT Aim Historical processes have shaped the Carpathian biogeography, yet ongoing evolutionary forces continue to drive population differentiation. We aimed to test whether local adaptation in the Carpathian subendemic Leucanthemum rotundifolium correlates with genetic, morphological and environmental factors, and to assess how these patterns ...

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Exploring the effects of anthropogenic habitat change on Euplerid carnivore occupancy in a humid evergreen forest, south‐east Madagascar

Journal of Zoology, EarlyView.
We collected camera trap data of small carnivores in Tsitongambarika Nouvelle Aire Protégée, south‐east Madagascar, and detected four endemic Euplerid species, that is, Cryptoprocta ferox, Fossa fossana, Galidia elegans, and Galidictis fasciata, and three non‐native species, that is, Viverricula indica, Canis familiaris, and Felis sp.

Investigating Harvest and Vessel Traffic Exposure as Drivers of Social Group Characteristics in Canadian Beluga (Delphinapterus leucas) Populations

Marine Mammal Science, EarlyView.
ABSTRACT Assessing variation in social behaviors of group‐living animals may provide insight into the impacts of population stressors. Using very high resolution (VHR) satellite imagery acquired over 3 years, we compared social group size and composition, as well as spatial and social cohesion in three beluga (Delphinapterus leucas) populations that ...
