“…Understanding the effects of water shortage on the conservation status of terrestrial and semi-terrestrial animals is crucial since droughts are becoming more frequent and intense in some parts of the world with climate change ( Cook et al , 2014 ; Trenberth et al , 2014 ). Droughts have direct physiological effects on organisms, such as an increased risk of lethal dehydration that can cause mass mortality events and rapid population declines in birds, mammals and amphibians ( Albright et al , 2017 ; McMenamin et al , 2008 ; Tsuji et al , 2018 ) with potential impacts on trophic networks and communities ( DuBose et al , 2019 ; McCreedy and Riper, 2015 ). However, the sub-lethal effects of water shortage on the physiology and life history of terrestrial animals remain relatively underexplored relative to the indirect effects mediated by trophic interactions ( Amorim et al , 2015 ; Sperry and Weatherhead, 2008 ).…”

Droughts are becoming more intense and frequent with climate change. These extreme weather events can lead to mass mortality and reproduction failure, and therefore cause population declines. Understanding how the reproductive physiology of organisms is affected by water shortages will help clarify whether females can adjust their reproductive strategy to dry conditions or may fail to reproduce and survive. In this study, we investigated the consequences of a short period of water deprivation (2 weeks) during early pregnancy on the physiology and behaviour of a cold- and wet-adapted ectotherm (Vipera berus). We also examined water allocation to developing embryos and embryonic survival. Water-deprived females exhibited significant dehydration, physiological stress and loss of muscle mass. These effects of water deprivation on water balance and muscle loss were correlated with the number of developing embryos. While water-deprived females maintained water transfer to embryos at the expense of their own maintenance, water deprivation also led to embryonic mortality. Overall, water deprivation amplifies the reproductive costs of water allocation to support embryonic development. The deleterious impacts of water deprivation on female current reproductive performance and on potential survival and future reproduction could lead to severe population declines in this species.

Tsuji Y, Prayitno B, Tatewaki T, Widayati KA, Suryobroto B. 2019. Short Communication: A report on ranging behavior of Malayan flying lemurs, Galeopterus variegatus, in West Indonesia: Relationships with habitat characteristics. Biodiversitas 20: 430-435. We attached GPS telemeters to wild Malayan flying lemurs, or colugos (Galeopterus variegatus) (n = 3, one adult male, one adult female, one juvenile male) in Pangandaran Nature Reserve, West Java, Indonesia in August 2018, to preliminary evaluate their home range size and characteristics, paying special attention to relationships with forest structure. Home range sizes, generated from location points collected from 4 to 11 days, ranging from 1.2 to 5.4 ha (based on minimum convex polygon method) or from 1.3 to 4.2 ha (95% Kernel), which is much larger than home ranges of colugos inhabiting palm plantations. The home range sizes of adult colugos were larger than that of juvenile. The home ranges of an adult female and a juvenile overlapped. The generalized linear model demonstrated that the locations where the colugos stayed frequently possessed a small number of trees and/or had a single taller tree, and these effects were stronger than other factors. The home range preferences of colugos seem to be related to gliding effectiveness and/or predator avoidance. The mean gliding distances were 33 m, but sometimes reached > 250 m, and there were no significant differences among animals. Night time gliding frequency showed no clear difference between time periods. We confirmed the effectiveness of GPS telemetry for tracking colugo movements.
