Water Availability and Hydraulic Strategies Control Leaf Thermoregulation and Damage During Heat Stress and Recovery in Temperate Tree Species

Plant, Cell &Environment, EarlyView.
Abstract Heatwaves are intensifying worldwide, often coinciding with high vapour pressure deficit (VPD) and soil drought. Yet, how temperate tree species tolerate these combined stresses remains elusive. Using single‐tree gas‐exchange chambers, we examined the response of leaf gas exchange and thermoregulation of three broadleaved tree species to a ...

Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

The influence of pupal colour on diapause and post‐diapause success in the swallowtail butterfly Papilio machaon

Physiological Entomology, EarlyView.
The swallowtail butterfly Papilio machaon has a brown‐ and green‐coloured morph, with the brown being more common in the diapausing generation. The darker colouration of brown pupae did not confer advantages for thermoregulation when developing, but they did have lower diapause metabolic rates.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Intermittent hand and forearm immersion in 20°C water attenuates thermal, cardiovascular, and perceptual strain in older adults during heat stress

Experimental Physiology, EarlyView.
Abstract Adults >65 years of age experience deleterious health effects during extreme heat events at a greater rate than any other age cohort. The purpose of this study was to identify the effectiveness of acute intermittent hand and forearm (H+F) water immersion and/or chronic (7 week) folic acid supplementation on reducing thermal and cardiovascular ...

Seven days of warm‐water immersion enhances resting irisin and BDNF, but not klotho, in older men

Experimental Physiology, EarlyView.
Abstract We examined whether seven consecutive days of warm‐water immersion could elevate resting and exercise‐induced levels of brain‐derived neurotrophic factor (BDNF), irisin and klotho in older adults. These biomarkers support cognitive and metabolic health, but their levels decline with age.
