Evidence suggests that energy-depleted, diffusion-dominated subseafloor environments in many cases have lower microbial temperature maxima (60-80 °C) 4 , 5 than environments with advective supplies of external microbial energy substrates. (nature.com)
Freixa A., Acuña V., Casellas M., Pecheva S., Romaní A.M. "Warmer night-time temperature promotes microbial heterotrophic activity and modifies stream sediment community. (udg.edu)

A variety of additives were found in the pore water of sediment, and they could explain over 90% of the variations of the community structure. (bvsalud.org)

Also lacking is an effective laboratory-based surveillance system for the early detection of exotic microbial agents that might be used for biological warfare or terrorist activities. (cdc.gov)

However, very little is known about how microbial communities respond to vegetation and multiple climate change factors. (confex.com)
Climate change in the form of reduced snowfall in mountains is causing powerful and cascading shifts in mountainous plant and bird communities through the increased ability of elk to stay at high elevations over winter and consume plants, according to a groundbreaking study. (sciencedaily.com)
Massively mobilized herbarium records are an underused resource that hold the promise of revealing how microbial communities respond to rapid shifts in climate due to human activity. (tamucc.edu)

This transformative shift in the automotive industry is becoming increasingly evident, with the year 2023 potentially marking a pivotal tipping point. (tunein.com)
June 27, 2023 A recent study shows that European bird communities have shifted northeastward in the past 30 years. (sciencedaily.com)

Antigenic shifts are probably due to genetic recombination (an exchange of a gene segment) between influenza A viruses that affect humans and/or animals. (cdc.gov)

Nitrogen-rich dissolved organic matter (DOM) inputs from effluents increased bacterial production and decreased primary production and community respiration. (lu.se)
