Subsistence harvest for food and pets associated with declining global mammal populations

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Subsistence harvest can have substantial impacts on mammalian biodiversity, yet its effects on the conservation status of mammal species are poorly understood. We analyzed trade and use data in species accounts from the International Union for Conservation of Nature (IUCN) Red List to examine the effects of subsistence harvest on the conservation ...

Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

open access: yesOikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.
