Impacts of hypoxia on boreal lake biogeochemistry and productivity : a 4-year whole-ecosystem BACI experiment

Climate warming is increasing thermal stratification depth, strength, and duration in lakes, leading to more frequent hypolimnetic oxygen depletion. Most research has focused on eutrophic temperate lakes, which differ significantly from boreal lakes that

Bridging the divide between models of animal‐driven and microbial‐driven biogeochemical cycling: A zoogeochemistry‐informed framework

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most current terrestrial biogeochemical models formalize biogeochemical cycling as predominantly controlled by processes involving plants and soil microbes. However, growing evidence indicates that above‐ground animals could exert controlling feedback effects that alter

Quantifying seasonal to multi-decadal signals in coastal water quality using high- and low-frequency time series data

Cambridge Prisms: Coastal Futures
To inform water quality monitoring techniques and modeling at coastal research sites, this study investigated seasonality and trends in coastal lagoons on the eastern shore of Virginia, USA.

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

The Impact of Parametric Uncertainties on Biogeochemistry in the E3SM Land Model

Journal of Advances in Modeling Earth Systems, 2018
We conduct a global sensitivity analysis (GSA) of the Energy Exascale Earth System Model (E3SM), land model (ELM) to calculate the sensitivity of five key carbon cycle outputs to 68 model parameters.

Interspecific and Intrashell Stable Isotope Variation Among the Red Sea Giant Clams

Geochemistry, Geophysics, Geosystems, 2020
The Gulf of Aqaba is home to three giant clam species with differing ecological niches and levels of photosymbiotic activity. Giant clams grow a two‐layered shell where the outer layer is precipitated in close association with photosymbiont‐bearing ...

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

Using light stable isotopes to understand nutrient cycling in soils and how these isotopic techniques can be leveraged to investigate the ecology and biology of insects – A review

Die Bodenkultur, 2018
At first glance, there appears little to link nitrogen cycling with entomology other that the use of isotope techniques. Soil management requires a contextual, adaptive, flexible approach that is based on understanding the factors that regulate the soil ...
