Needing a drink: Rainfall and temperature drive the use of free water by a threatened arboreal folivore.. Arboreal folivores are particularly vulnerable to the impacts of extreme climate change-driven heatwaves and droughts as they rely on leaf moisture to maintain hydration. During these increasingly frequent and intense weather events, leaf water content may not be enough to meet their moisture requirements, potentially leading to large-scale mortality due to dehydration. Water supplementation could be critical for the conservation of these animals. We tested artificial water stations for a threatened arboreal folivore, the koala (Phascolarctos cinereus), as a potential mitigation measure…

Hot climate, hot koalas: the role of weather, behaviour and disease on thermoregulation.. Thermoregulation is critical for endotherms living in hot, dry conditions, and maintaining optimal core body temperature ( T b ) in a changing climate is an increasingly challenging task for mammals. Koalas ( Phascolarctos cinereus ) have evolved physiological and behavioural strategies to maintain homeostasis and regulate their T b but are thought to be vulnerable to prolonged heat. We investigated how weather, behaviour and disease influence T b for wild, free-living koalas during summer in north-west New South Wales. We matched T b with daily behavioural observations in an ageing population where ch…

How Much Water Should You Drink Daily?. Daily water intake is a vital part of staying healthy, yet many people are unsure how much water they should drink. This article explains how much water the body needs each day and what factors affect hydration levels. It addresses common questions like whether other beverages count as water, if thirst is a reliable signal, and how much water to drink based on body weight or activity level. It also explores hydration needs for different age groups, climates, and medical conditions.
