As Earth’s atmosphere accumulates carbon dioxide (CO2) and other greenhouse gases, Earth’s climate is expected to warm and precipitation patterns will likely change. The manner in which terrestrial ecosystems respond to climatic changes will in turn affect the rate of climate change. Here we describe responses of an old-field herbaceous community to a factorial combination of four levels of war...

A central question at the interface of food-web and climate change research is how secondary production, or the formation of heterotroph biomass over time, will respond to rising temperatures. The metabolic theory of ecology (MTE) hypothesizes the temperature-invariance of secondary production, driven by matched and opposed forces that reduce biomass of heterotrophs while increasing their bioma...

background: the utilization of immature oocytes derived from stimulated cycles could be of great importance, specially for urgent fertility preservation cases. the aim of the current study was to determine whether in-vitro maturation is more successful before or after the vitrification of these oocytes. materials and methods: the study was performed in a private ivf center. 318 germinal vesicle...

As a consequence of the growing concern about warming of the Arctic Ocean, this study quantified the thermal acclimation responses of Boreogadus saida, a key Arctic food web fish. Physiological rates for cardio-respiratory functions as well as critical maximum temperature (Tc,max) for loss of equilibrium (LOE) were measured. The transition temperatures for these events (LOE, the rate of oxygen ...

OBJECTIVES The study compares the efficacy of two active and one passive warming interventions in healthy volunteers with induced mild hypothermia. METHODS Eight volunteers were studied in a random order crossover design. Each volunteer was studied during re-warming from a core temperature of 35 degrees C with each of: a radiant warmer (Fisher & Paykel); a forced air warmer (Augustine Medical...

BACKGROUND This study was designed to evaluate the effects of blood warming during hemofiltration on global and regional hemodynamics, plasma lactate, and 24-h survival during septic shock. METHODS Twenty anesthetized and mechanically ventilated sheep underwent induction of peritonitis and, 4 h later, were treated by hemofiltration with (n = 10) or without (n = 10) blood warming. RESULTS In...
