An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles

open access: yesIntegrative Zoology, EarlyView.
We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

open access: yesIntegrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Phenological description for the initial development stage of five Brazilian native forest species according to BBCH scale

open access: yesAnnals of Applied Biology, EarlyView.
Morphology of the two main growth stages—germination and initial development of the forest species Ceiba speciosa (co, cotyledon; eo, eophyll; hp, hypocotyl; me, metaphyll; pk, prickles; pr, primary root; se, seed; sr, secondary root). Abstract A specific phenological scale designated for each forest species facilitates the standardization of different

Development of a novel risk score reflecting the relative harm potential of synthetic cannabinoids based on prevalence estimates, well‐documented intoxication cases and basic pharmacological data

open access: yesAddiction, EarlyView.
Abstract Background and aims While the health hazards of synthetic cannabinoid receptor agonists (SCRAs) are often approximated using in vitro pharmacological parameters as surrogate, this approach fails to consider pharmacokinetic and pharmacodynamic complexity.

Exposures in Indoor Air Affecting Health

open access: yesAllergy, EarlyView.
ABSTRACT Indoor air quality (IAQ) is influenced by a wide range of chemical, biological and physical agents that can negatively impact physical, immunological and mental health. Adverse health effects depend on the type and concentration of pollutants, duration of exposure, and individual susceptibility.

School achievement in the Brazilian rural Amazon: An analysis of the interaction among motor, cognitive and environmental factors

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract A cross‐sectional study of 106 students (7–12 years) from a rural school in the Brazilian Amazon investigated the interaction among motor, cognitive and environmental factors on school achievement using network analysis. Students with good school performance were significantly older and showed superior global physical fitness, motor ...
