Contributions to physiological climatology

Genetic and Physiological Contributions to Obesity

Organismal climatology: analyzing environmental variability at scales relevant to physiological stress.

Predicting when, where and with what magnitude climate change is likely to affect the fitness, abundance and distribution of organisms and the functioning of ecosystems has emerged as a high priority for scientists and resource managers. However, even in cases where we have detailed knowledge of current species' range boundaries, we often do not understand what, if any, aspects of weather and c...

Tropical stratospheric cloud climatology from the PATMOS‐x dataset: An assessment of convective contributions to stratospheric water

[1] The PATMOS‐x level 2b climatology, generated using three decades of AVHRR measurements, contains valuable information about the past global cloud record. We extract climatologies of tropical deep convective clouds from the PATMOS‐x data set, based on the 10.30–11.30 mm brightness temperature. A comparison of the cross tropopause convective cloud frequency between ISCCP and PATMOS‐x shows th...

Responses of Bacillus subtilis to hypotonic challenges: physiological contributions of mechanosensitive channels to cellular survival.

Mechanosensitive channels are thought to function as safety valves for the release of cytoplasmic solutes from cells that have to manage a rapid transition from high- to low-osmolarity environments. Subsequent to an osmotic down-shock of cells grown at high osmolarity, Bacillus subtilis rapidly releases the previously accumulated compatible solute glycine betaine in accordance with the degree o...
