Researchers identify nutrient enrichment driven by canopy rainfall redistribution
Precipitation deeply couples with nutrient cycling through its interactions with atmospheric deposition and canopy interception, which alters its own chemical properties. Throughfall and stemflow carry numerous elements into the soil, not only affecting the structure of soil microbial communities, individual plant survival, and plant community succession, but also regulating ecosystem structure and function. This constitutes a key ecological process that connects the atmosphere, phyllosphere,...

New approach expands quantification of nutrient exchange in plant tissues, the rhizosphere and soil
Organic carbon in soil is linked to enhanced plant growth and to improved subsurface biodiversity, and it is a potential sink for atmospheric carbon dioxide (CO2). Yet, injection of organic carbon into soil through various root processes is typically focused on small spatial regions, which can confound attempts to quantify the carbon and correlate it with various microenvironments that exist around plant roots.

Weaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change
Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions about how our oceans might react to a changing climate—and what that means for ocean life.
