Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna. [PDF]
Conserv BiolAbstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts. [PDF]
Conserv BiolAbstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...

Biophysical Journal, 1973 Six solutes known to be actively transported by bacteria were studied with the cell in a "minimum energy" state to determine if sufficient energy were available from cellular stores of ATP to supply the energy necessary to run postulated membrane-situated "pumps." Steady-state cellular concentrations of potassium, calcium, magnesium, leucine, glycine ...
