Biogeochemical Processes in the Active Layer and Permafrost of a High Arctic Fjord Valley

Frontiers in Earth Science, 2020
Warming of ground is causing microbial decomposition of previously frozen sedimentary organic carbon in Arctic permafrost. However, the heterogeneity of the permafrost landscape and its hydrological processes result in different biogeochemical processes ...

Environmental Impacts—Freshwater Biogeochemistry [PDF]

, 2015
Climate change effects on freshwater biogeochemistry and riverine loads of biogenic elements to the Baltic Sea are not straight forward and are difficult to distinguish from other human drivers such as atmospheric deposition, forest and wetland management , eutrophication and hydrological alterations. Eutrophication is by far the most well-known factor

Shared leadership can promote success in collaborative research networks in ecology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While collaborative science is becoming the norm in ecology, many ecologists participating in collaborations are less aware of the body of research that studies the processes by which collaborative teams organize and communicate.

Equilibration of the terrestrial water, nitrogen, and carbon cycles [PDF]

, 1997
Recent advances in biologically based ecosystem models of the coupled terrestrial, hydrological, carbon, and nutrient cycles have provided new perspectives on the terrestrial biosphere’s behavior globally, over a range of time scales.

Tree species diversity drives above‐ground carbon sequestration through light‐related trait shifts

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits can vary in response to tree species mixing, which in turn might influence biomass production and, consequently, carbon (C) sequestration in diverse forests.

Controls on the composition and lability of dissolved organic matter in Siberia's Kolyma River basin [PDF]

, 2012
High-latitude northern rivers export globally significant quantities of dissolved organic carbon (DOC) to the Arctic Ocean. Climate change, and its associated impacts on hydrology and potential mobilization of ancient organic matter from permafrost, is ...

Graph tools for analysing trophic assemblies in the isotopic space

Methods in Ecology and Evolution, EarlyView.
Abstract A large amount of information on the trophic assembly of ecosystems is summarized in the isotopic space, and metrics for extracting this information are essential. Here, we show how the characterization of the isotopic space as an isotopic‐network of organisms linked by their trophic similarity significantly expands the isotopic toolbox for ...

Longitudinal transformation of nitrogen and carbon in the hyporheic zone of an N-rich stream: A combined modelling and field study [PDF]

, 2011
A combined modelling and field study approach was used to examine biogeochemical functioning of the hyporheic zone in two gravel bars in an N-rich fourth-order stream (River Hers, south-west France).

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, EarlyView.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...
