CO2 emissions from subaerial volcanoes

GwynneL.

The emissions of CO2 and other volatiles from the world's subaerial volcanoes SUMMARY: Volcanoes play an important role in recycling carbon dioxide. This study takes a closer look at the amount emitted into the atmosphere by volcanoes that aren't underwater. Out of 900 volcanoes, only 500 have detectable degassing activity (i.e. they are emitting gases).… Continue reading CO2 emissions from subaerial volcanoes

Environmental impacts on the diversity of methane-cycling microbes and their resultant function

GwynneL.

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

GwynneL.

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

Protozoa and plant growth: the microbial loop in soil revisited

GwynneL.

Protozoa and plant growth: the microbial loop in soil revisited (NOT OPEN ACCESS) SUMMARY: This is an in-depth review on the rhizosphere and the interactions between protozoa, nematodes, and plant roots. LESSON COMMENTS: This can be read like a textbook for students. Alternatively, teachers can assign relevant sections. The rhizosphere can be grown and observed… Continue reading Protozoa and plant growth: the microbial loop in soil revisited

Understanding Ocean Currents in the Atlantic Ocean

GwynneL.

North Atlantic Ocean Circulation and Decadal Sea Level Change During the Altimetry Era SUMMARY: This article talks about the changes in the temperature of the North Atlantic Ocean in the last two decades due to the North Atlantic Oscillation (a weather phenomenon that is caused by the way water circulates in the ocean). Researchers want… Continue reading Understanding Ocean Currents in the Atlantic Ocean
