Out of the deep-sea into a land-based aquarium environment: Investigating innate immunity in the hydrothermal vent mussel Bathymodiolus azoricus ArchiMer

Deep-sea hydrothermal vents are considered as some of the most adverse environments in the world, yet the animals dwelling around the vent sites exhibit high productivity and therefore must cope with unusual levels of heavy metals, pH, temperature, CO2 and sulfide, in addition to environmental microbes. In an attempt to understand the physiological reactions of animals normally set to endure extreme conditions we investigated molecular indicators of acclimation processes during which the mussel Bathymodiolus azoricus was maintained over long periods of time under without methane and/or sulfide supplementation, vent mussels seem to endure well aquarium conditions. The presence and induction of a Rel Homology Domain containing gene was investigated along...

Responses and adaptations of collembolan communities (Hexapoda: Collembola) to flooding and hypoxic conditions. Repositório Alice
MARX, M. T.; WILD, A.-K.; KNOLLMANN, U.; KAMP, G.; WEGENER, G.; EISENBEIS, G..
Abstract ? Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of several collembolan species were analyzed using a...

Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity.

The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of several collembolan species were analyzed using a microcalorimeter. The...
