Field and lab conditions alter microbial enzyme and biomass dynamics driving decomposition of the same leaf litter SUMMARY: This study looked at the rate of decay between litter in lab conditions and natural conditions. They used fallen leaves from dogwood trees, oak trees, maple trees, and maple-oak tree mix. Results showed quite a difference in… Continue reading Field and lab conditions alter microbial enzyme and biomass dynamics

Environmental impacts on the diversity of methane-cycling microbes and their resultant function
Environmental impacts on the diversity of methane-cycling microbes and their resultant function SUMMARY: There are two types of microbes that are involved in methane cycling: ones that produce methane (methanogens) and ones that use methane as a source of energy and convert it to carbon dioxide (methanotrophs). This article review looked at all the different… Continue reading Environmental impacts on the diversity of methane-cycling microbes and their resultant function
Moss-Cyanobacteria relationship in the boreal forest
Moss-cyanobacteria associations as biogenic sources of nitrogen in boreal forest ecosystems SUMMARY: Moss, cyanobacteria, and the trees of the boreal forest share a complicated relationship. This article first focuses on the nitrogen cycle, addressing the various sources of nitrogen and the factors (both abiotic and biotic) that affect nitrogen fixation. Turns out, temperature, water availability,… Continue reading Moss-Cyanobacteria relationship in the boreal forest
Beaming Simulated Space Ice
Enantiomeric separation of complex organic molecules produced from irradiation of interstellar/circumstellar ice analogs(NOT OPEN ACCESS) SUMMARY: To simulate conditions in space and in asteroids and meteorites, scientists put simple gases (water, carbon dioxide, ammonia, and methanol) into a low temperature and low pressure chamber. Then, using UV light, they irradiated these gases (which at the… Continue reading Beaming Simulated Space Ice
Modeling Ecosystem Invasions with Bacteria
Invasion triple trouble: Environmental fluctuations, fluctuation-adapted invaders and fluctuation-mal-adapted communities all govern invasion success SUMMARY: To model how ecosystems react to invaders and temperature changes (due to global warming), researchers used different bacteria clones to simulate invasions. Results showed that communities in fluctuating temperatures were more susceptible to invasion compared to communities with constant temperatures.… Continue reading Modeling Ecosystem Invasions with Bacteria
