Arbuscular mycorrhizal (AM) fungal networks are vast underground systems that form symbiotic relationships with the majority of Earth's plant species, exchanging water and nutrients for plant-fixed carbon. A recent global mapping effort revealed these living infrastructures possess a total length of approximately 110 quadrillion kilometers and a mass of roughly 300 megatons of carbon.

#Introduction

I'm a PhD candidate at the Kansas Geological Survey & University of Kansas studying non-perennial streams, carbon cycling, and biogeochemistry. Interested in ecosystem ecology, hydrology, rstats, and data viz. I’ll mostly post about non-perennial streams, aquatic ecology, fieldwork, and reproducible science.

Oysters continuously filter coastal waters and deposit excess nitrogen into the ocean floor sediment, a natural process known as nitrogen burial. A recent study demonstrates that this ecosystem service has an economic value 42% higher than previously estimated.

In this comprehensive research report, we undertake an extensive examination of one of the most transformative biological discoveries of the modern scientific era. For centuries, the foundational dogma of terrestrial ecology was absolute: the sun was the ultimate and singular source of energy capable of sustaining complex life.

Experimental exposure to elevated CO2 demonstrates that understory trees in the Amazon initially increase their carbon uptake and growth, though this long-term capacity is ultimately constrained by soil nutrient availability.

Amazon understory forests show short-term boost in CO₂ uptake – but this comes at a cost

Experimental increases in CO₂ stimulated plant growth are facilitated by re-distributed root systems to extract nutrient resources more efficiently

Not all giant icebergs, or "megabergs," release fertilizing nutrients into the ocean as they melt; their capacity to stimulate marine life and absorb atmospheric carbon varies drastically depending on their individual life cycles and histories.

Rivers worldwide are progressively warming and losing oxygen, a transformation that turns them into significant, under-accounted sources of greenhouse gases (GHGs). The influx of agricultural and urban nutrients, combined with rising temperatures, fuels microbial activity that releases carbon dioxide, methane, and nitrous oxide into the atmosphere.
