Periphyton Function in Lake Ecosystems [PDF]
The Scientific World JOURNAL, 2002 Periphyton communities have received relatively little attention in lake ecosystems. However, evidence is increasing that they play a key role in primary productivity, nutrient cycling, and food web interactions. This review summarizes those findings and places them in a conceptual framework to evaluate the functional importance of periphyton in lakes.

From atoms to ecosystems: elementome diversity meets ecosystem functioning [PDF]
New Phytologist, 2021 SummaryThe elemental composition of plants (the elementome) is a reliable indicator of their functional traits and the ecological strategies that they follow, and thus represents a good predictor of how ecosystems work. Biodiversity and, especially, functional diversity are also widely recognized as important drivers of ecosystem functioning, mainly ...

Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]
, 2012 Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Scaling‐up biodiversity‐ecosystem functioning research [PDF]
Ecology Letters, 2020 AbstractA rich body of knowledge links biodiversity to ecosystem functioning (BEF), but it is primarily focused on small scales. We review the current theory and identify six expectations for scale dependence in the BEF relationship: (1) a nonlinear change in the slope of the BEF relationship with spatial scale; (2) a scale‐dependent relationship ...

Specific root length regulated the rhizosphere effect on denitrification across distinct macrophytes
GeodermaMacrophytes influence nitrogen (N) removal from wetlands. However, the specific plant traits responsible for this effect and the related microbial mechanisms remain largely unknown, especially root traits.

Peatlands and the carbon cycle: from local processes to global implications - a synthesis [PDF]
, 2008 Peatlands cover only 3% of the Earth's land surface but boreal and subarctic peatlands store about 15-30% of the world's soil carbon ( C) as peat. Despite their potential for large positive feedbacks to the climate system through sequestration and ...

Aggressive prostate cancer is associated with pericyte dysfunction
Molecular Oncology, EarlyView.Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
