Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

Conservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

Effectiveness of different blood anticoagulants for artificial feeding of Aedes aegypti mosquitoes in the laboratory Eficiência de diferentes anticoagulantes para alimentação sanguínea artificial de mosquitos Aedes aegypti em laboratório

Medical and Veterinary Entomology, EarlyView.
Aedes aegypti females were allowed to feed, through an artificial feeder, on rabbit blood pre‐collected and defibrinated or treated with anticoagulants heparin or sodium citrate. The efficiency in producing a high percentage of engorged females and great fecundity and egg viability rates was compared among blood treatments and with females feeding ...

Mixed‐vertebrate pollination traits and pollinators of Haageocereus acranthus (Cactaceae) in a lomas desert ecosystem of coastal Peru

Plant Biology, EarlyView.
In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...
