Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, EarlyView.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Macronutrient composition in pollen affects development and survival in wild bees

Physiological Entomology, EarlyView.
Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Impact of emerging compound droughts on forests: A water supply and demand perspective

Plant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...

Trait‐based recovery of insect functional diversity following pine removal in a shrubland biodiversity hotspot

Restoration Ecology, EarlyView.
Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

How hot is too hot for people? A review of empirical models of perceptual, physiological and functional limits of human heat tolerance

Experimental Physiology, EarlyView.
Abstract How hot is too hot for people? This is a question that human thermal physiologists are asked often by a variety of knowledge users across the public and private sectors, who have grown aware of the negative impact of global warming on people's health and quality of life.

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 ...
