Significant improvements have been made in estimating gross primary production (GPP),
ecosystem respiration (R), and net ecosystem production (NEP) from diel,“free‐water” …

This review provides a synthesis of limnological data and conclusions from studies on ponds
and small lakes at our research sites in Subarctic and Arctic Canada, Alaska, northern …

We explore the role of lakes in carbon cycling and global climate, examine the mechanisms
influencing carbon pools and transformations in lakes, and discuss how the metabolism of …

Carbon in thawing permafrost soils may have global impacts on climate change; however,
the factors that control its processing and fate are poorly understood. The dominant fate of …

Because freshwater covers such a small fraction of the Earth's surface area, inland
freshwater ecosystems (particularly lakes, rivers, and reservoirs) have rarely been …

One of the major impediments to the integration of lentic ecosystems into global
environmental analyses has been fragmentary data on the extent and size distribution of …

Freshwater reservoirs are a known source of greenhouse gas (GHG) to the atmosphere, but
their quantitative significance is still only loosely constrained. Although part of this …

Peatlands, soils and the ocean floor are well-recognized as sites of organic carbon
accumulation and represent important global carbon sinks,. Although the annual burial of …

Microbial ecology is the study of interactions among microbes in natural environments and
their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes …

Invisible to the naked eye lies a tremendous diversity of organic molecules and organisms
that make major contributions to important biogeochemical cycles. However, how the …
