Streams and rivers form dense networks, shape the Earth's surface and, in their sediments,
provide an immensely large surface area for microbial growth. Biofilms dominate microbial …

Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Mean annual temperature and mean annual precipitation drive much of the variation in
productivity across Earth's terrestrial ecosystems but do not explain variation in gross …

Lakes and impoundments are important sources of greenhouse gases (GHG: ie, CO2, CH4,
N2O), yet global emission estimates are based on regionally biased averages and …

A substantial amount of the atmospheric carbon taken up on land through photosynthesis
and chemical weathering is transported laterally along the aquatic continuum from upland …

While there is an emerging view that roots and their associated microbes actively alter
resource availability and soil organic matter (SOM) decomposition, the ecosystem …

Understanding the dynamics of methane (CH 4) emissions is of paramount importance
because CH 4 has 25 times the global warming potential of carbon dioxide (CO 2) and is …

Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

In this re-evaluation of our 10-year old paper on priming effects, I have considered the latest
studies and tried to identify the most important needs for future research. Recent …

Nitrogen (N) and/or phosphorus (P) availability can limit growth of primary producers across
most of the world's aquatic and terrestrial ecosystems. These constraints are commonly …
