The deep-sea hydrothermal vent mussel Bathymodiolus azoricus has been the subject of several studies aimed at understanding the physiological adaptations that vent animals have developed in order to cope with the particular physical and chemical conditions of hydrothermal environments. In spite of reports describing successful procedures to maintain vent mussels under laboratory conditions at a...
[1] Explosive volcanic eruption columns are generally subdivided into a gas-thrust region and a convection-dominated plume. Where vents have greater than atmospheric pressure, the gas-thrust region is overpressured and develops a jet-like structure of standing shock waves. Using a pseudogas approximation for a mixture of tephra and gas, we numerically simulate the effects of shock waves on the ...
indirectly provides oxygen, a byproduct of photosynthesis, which aerobic chemosynthetic microorganisms require to synthesize organic carbon from CO2. Planktonic life stages of many vent and cold seep invertebrates also directly feed on photosynthetically produced organic matter as they disperse to new vent and seep systems. While a large portion of the life at deep-sea chemosynthetic habitats c...
malformations which occur during the development of the avian body organs can lead to structural and functional abnormalities. most defects are recognized at hatching, but some go undetected until somewhat later. the cause of the majority of animal congenital malformations is unknown. a significant proportion of congenital malformations of unknown cause are likely to have an important genetic c...
(Leaf damage in a mangrove swamp at Sepetiba Bay, Rio de Janeiro, Brazil). Leaf damage to Rhizophora mangle L., Avicennia schaueriana Stapf. & Leechman, and Laguncularia racemosa L. was studied in a two hectare mangrove swamp site in Sepetiba Bay. Seventeen arthropod morphospecies were identifi ed as being responsible for the damage, and their species diversity was highest on A. schaueriana, fo...

Studies of genetic connectivity and population structure in deep-sea chemosynthetic ecosystems often focus on endosymbiont-hosting species that are directly dependent on chemical energy extracted from vent effluent for survival. Relatively little attention has been paid to vent-associated species that are not exclusively dependent on chemosynthetic ecosystems. Here we assess connectivity and po...
