THE ISOLATION AND CHARACTERIZATION OF NOVEL EXTREME HALOPHILIC ARCHAEA FROM A LOW-SALT, SULFIDE- AND SULFUR-RICH SPRING.
(2009)
The archaeal community of a low-salt, sulfur-rich spring in south-western Oklahoma, was analyzed at two different locations along the spring. Interestingly, 36% of the archaeal mat clone library and 4% of the source clone ...
Microbial penetration through Berea sandstone and the effect of nitrate on biogenic sulfide production :
(1985)
Results from energy dispersion spectroscopy, and electron microscopy of autoclaved and dry-heat sterilized rock revealed that changes in mineral content and clay morphology of autoclaved rock could account for faster ...
Habitat relationships and habitat variability of the wood warblers (Parulidae)
(1981)
Based on 13 structural variables, the habitat structure of 16 species of wood warblers breeding in north-central Minnesota can be divided into three general habitat types: open country, shrub-forest edge, and mature forest. ...
Remote sensing analysis of croplands, woody plant encroachment and carbon fluxes of woody savanna
(2017-05-12)
Since 1990s, much attention has been paid to Land use/land cover change (LULCC) studies because it is an important component of global change. The vegetation change is a critical factor of land cover changes, which interacts ...
Exploring ecological and biogeographic questions using biological databases derived from natural history collections and surveys
(2009)
Biogeographic research has benefited from the digitizing of large databases derived from natural history collections and biological surveys. These resources made available via the Internet can be accessed by biogeographers ...
Anaerobic reduction of hexavalent chromium by subsurface microorganisms.
(1999)
Anaerobic sediments from an aquifer contaminated with landfill leachate were used to study the potential for microbial reduction of Cr(VI) to Cr(III). The lightly colored, sandy sediments slowly reduced Cr(VI) in viable, ...
Factors involved in cellular sensitivity to anthrax lethal toxin.
(2005)
The lethal factor (LF) component of Bacillus anthracis lethal toxin (LeTx) cleaves mitogen activated protein kinase kinases (MAPKKs) in a variety of different cell-types, yet not all cells are susceptible to the toxin. ...
Characterizing the effect of habitat structure on microbial community assembly and secondary metabolism for natural product discovery
(2021-08)
Microorganisms exist in dynamic networks that catalyze reactions and respond to stimuli. They organize into populations that make up the microbial communities we know to drive large-scale biogeochemical cycles that can ...
