stress tolerance
- Natural polymorphism in protein kinase G modulates functional senescence in Drosophila melanogaster
Summary: PKG, encoded by the polymorphic foraging gene, confers hypoxia tolerance at the expense of lifespan and healthy aging, indicating a novel role for PKG in aging and senescence.
- The role of stochastic thermal environments in modulating the thermal physiology of an intertidal limpet, Lottia digitalis
Editors' Choice: Aerial exposure and recent thermal history, paired with relief from high low-tide temperatures, are important factors modulating the capacity of limpets to deal with repeated thermal stress in an intertidal environment.
- Physiological mechanisms used by fish to cope with salinity stress
Summary: Some fishes have evolved high salinity stress tolerance (euryhalinity), favoring adaptive radiation in a climate of rapidly changing and fluctuating salinity. The mechanisms underlying euryhalinity of fishes are outlined.
