A new
obligately chemolitho autotrophic, nitrite-oxidizing bacterium, Nitrospira moscoviensis sp.nov.
Although clonal reproduction is expected to be reproductively advantageous (Maynard-Smith 1978; Bell 1982),
obligately asexual organisms are short-lived on geologic time scales and have been regarded as evolutionary dead ends (Bell 1982; Lorenzo-Carballa et al.
Evolutionary impacts of hybridization and interspecific gene flow on an
obligately estuarine fish.
Obligately intracellular Rickettsia spp., typically transmitted by ticks, cause a multitude of mild to severe rickettsial diseases in humans and other animals.
Under the
obligately anaerobic conditions, QMA with four methyl moieties serves as an excellent substrate for methane production through methanogenesis pathways.
acidophilus is an
obligately homofermentative bacteria (produces lactic acid as main metabolic product) while L.
They are
obligately dependent on the fungi they grow, though displaying great variation in their ecology (Mehdiabadi & Schultz 2010).
Given that tau hyperphosphorylation precedes aggregation, and tau aggregates are
obligately phosphorylated in AD brain, phosphorylation has been suggested as a primary trigger for tau aggregation.
When a hypolimnion remains anoxic,
obligately anaerobic prokaryotic populations, including Archaeal methanogens, presumably increase, but a lake that never has an oxygenated hypolimnion due to salt-induced stratification likely produces more methane because conditions that favor methanogen growth are persistent.
Individual variation in feeding habitat use by adult female green sea turtles (Chelonia mydas): are they
obligately neritic herbivores?
