Leaf senescence is a natural age-dependent process that is induced prematurely by various environmental stresses. Typical alterations during leaf senescence include breakdown of chlorophyll, a shift to catabolism of energy reserves, and induction of senescence-associated genes, all of which can occur during submergence, drought, and constant darkness. Here, we evaluated the influence of the sub...

Saline water intrusion into freshwater aquifers is a major geohydraulic problem relevant to coastal environment. Apart from contaminating the fresh groundwater resources, saltwater alters geotechnical properties of aquifer materials, affecting resource planning and management. The present study focuses on an in-depth laboratory investigation influence submergence sand. fine sand sample was subm...

Anoxic submergence in the Western painted turtle results in a severe metabolic acidosis characterized by high plasma lactate and depressed arterial pH, a response similar to that seen in other vertebrates following exhaustive exercise. We tested the hypothesis that 1 or 2 h of aerobic swimming following anoxic submergence would enhance the rate of lactate disappearance from the blood just as su...

[1] We utilize coral microatolls in western Sumatra to document vertical deformation associated with subduction. Microatolls are very sensitive to fluctuations in sea level and thus act as natural tide gauges. They record not only the magnitude of vertical deformation associated with earthquakes (paleoseismic data), but also continuously track the long-term aseismic deformation that occurs duri...
