Winter Fat Storage and Vertical Microenvironmental Gradients: Experimental Test of an Alternative Hypothesis
Cost-benefit optimal body mass models have become a cornerstone of behavioral ecology of the nonbreeding period of birds, and make the prediction that fat will increase with increasing deterioration of feeding conditions. Tests of this prediction have relied on comparing fat stores of birds along a vertical height gradient of resource unpredictability (greater snowfall nearer the ground), and l...
متن کاملRate of development of Hydrotaea rostrata under summer and winter (cyclic and constant) temperature regimes.
The black carrion fly Hydrotaea rostrata Robineau-Desvoidy (Diptera: Muscidae) is a muscid, which occurs on approximately one-third of decomposing human corpses involved in homicide cases in south-western Australia. Work to date on its development rates is scant with only one published source available. The current study measured the precise developmental rates of this species using high repeti...
متن کاملResponse of freshwater microcosm communities to nutrients, fish, and elevated temperature during winter and summer
Under conditions of stress, shallow freshwater ecosystems can undergo a state change characterized by the rapid loss of macrophytes and subsequent dominance of phytoplankton. Elevated water temperature may promote such change. Here we report the impact of two warming regimes (continuous 38C above ambient and 38C above ambient during summer only), with two nutrient loadings and the presence or a...
متن کاملDifferences in physiological responses between winter and summer Gracilaria tenuistipitata (Gigartinales, Rhodophyta) to varying temperature
Gracilaria tenuistipitata var. liui Zhang et Xia, which is farmed in brackish water ponds of southern Taiwan as a major food of sea abalone, produces poor yields in winter. This study investigated the effects of year, location (pond), and season on the physiological responses of G. tenuistipitata to varying temperature. Neither year nor pond affected the physiological parameters. Season signifi...
متن کاملEffect of Previous-Winter Mortality on the Association between Summer Temperature and Mortality in South Korea
BACKGROUND It has recently been postulated that low mortality levels in the previous winter may increase the proportion of vulnerable individuals in the pool of people at risk of heat-related death during the summer months. OBJECTIVES We explored the sensitivity of heat-related mortality in summer (June-August) to mortality in the previous winter (December-February) in Seoul, Daegu, and Inche...
