Mussels and Local Conditions Interact to Influence Microbial Communities in Mussel Beds

open access: yesFrontiers in Microbiology, 2022
Microbiomes are increasingly recognized as widespread regulators of function from individual organism to ecosystem scales. However, the manner in which animals influence the structure and function of environmental microbiomes has received considerably ...

Do ecosystems have functions?

open access: yesEcology and Evolution, 2023
‘Ecosystem function’ and ‘ecosystem functioning’ became core keywords in the ecological literature on ecosystems, their structure, development and integrity.

Fish extinctions and ecosystem functioning in tropical ecosystems [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
The activities of modern humans have increased the extinction rate of the world's species by up to 1,000 times that observed from the fossil record (1). This extinction crisis has motivated the scientific community to understand the consequences of reduced biodiversity for the dynamics of ecosystems, especially those that provide basic services to ...

Periphyton Function in Lake Ecosystems [PDF]

open access: yesThe 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.

Urban Landscapes and Sustainable Cities

open access: yesEcology and Society, 2006
Ecological research targeting sustainable urban landscapes needs to include findings and methods from many lines of ecological research, such as the link between biodiversity and ecosystem function, the role of humans in ecosystems, landscape ...

Ecological Zoning Based on Spatial Patterns of Ecosystem Service Values and Landscape Ecological Risk in the Miyun Reservoir Basin

open access: yesLand
Ecological zoning is important for understanding spatial heterogeneity and supporting landscape-level management. However, existing approaches rarely integrate ecosystem service supply with ecological risk, and their underlying nonlinear relationships ...

Scale Mismatches in Social-Ecological Systems: Causes, Consequences, and Solutions

open access: yesEcology and Society, 2006
Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Testing Bathymetric and Regional Patterns in the Southwest Atlantic Deep Sea Using Infaunal Diversity, Structure, and Function

open access: yesDiversity, 2020
A better understanding of deep-sea biology requires knowledge of the structure and function of their communities, the spatial, temporal, and environmental patterns, and the changes and dynamics that govern them.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
