Biodiversity and Biogeography of Deep-Sea Gastropod Mollusks from the Pacific Costa Rica Margin
… and described. Marine ecosystems fueled by chemosynthesis, such as hydrothermal vents and hydrocarbon seeps, represent biodiversity hotspots along the ocean floor. Yet, investigations into the diversity, genetic connectivity, and biogeography of life at such ecosystems are still ongoing. The …

Searching for life where the sun don't shine : explorations to the seafloors of Earth and Europa
… host entire ecosystems that live off energy from chemosynthesis rather than photosynthesis. This energy process uses chemical reactions between metals and hot gases from inside Earth's mantle to fuel thriving communities of exotic organisms. Some researchers think life originated at these vents …

Biodiversity, distribution patterns and trophic position of meiobenthos associated with reduced environments at continental margins
… by bacteria using energy of chemical bindings (chemosynthesis). Metazoan macro- and megafaunal life in reduced environments is generally characterised by low diversity (which however may increase to the periphery of the biotope), often high degree of endemism and peculiar biological traits. …

Marine parasites in island-like disturbed habitats
… in a new setting with distinct fauna and a chemosynthesis-based food web. Second, I compare parasite diversity at isolated, disturbed vents to marine ecosystems that are similarly isolated but undisturbed (atoll sandflat) and both well connected and undisturbed (kelp forest). Overall, …

Resolving functional resilience of microbial communities to climate-induced change in the McMurdo Dry Valleys of Antarctica
… evidence that carbon fixation via atmospheric chemosynthesis is the primary active pathway for carbon acquisition under extreme aridity in polar deserts, being replaced by photosynthetic carbon fixation with prolonged exposure to wetness. To complement predictions made in situ using a …

Stereoselectivity, kinetics, and engineering of flavin/deazaflavin oxidoreductases for use in industrial biocatalysis
… which are often technically challenging in chemosynthesis, find relevance in biocatalysis. Moreover, traditional chemical synthesis continues to face concerns about environmental costs and viability. Biocatalysts, such as enzymes, can address both concerns due to their high specificity and …
