An Improved Biotic Index of Organic Stream Pollution [PDF]
, 2017 Major improvements were made in using a biotic index of the arthropod fauna to evaluate organic stream pollution. All tolerance values were reevaluated, many were changed, and the scale for tolerance values was expanded to 0-10 to provide greater ...

Predators regulate prey species sorting and spatial distribution in microbial landscapes [PDF]
Journal of Animal Ecology, 2017 Summary The role of predation in determining the metacommunity assembly model of prey communities is understudied relative to that of interspecific competition among prey.

Frontiers in Microbiology, 2014 To understand mechanisms linking ecosystem processes and microbial diversity in freshwater ecosystems, bacterial productivity and the metacommunity dynamics of species sorting and mass effects were investigated in an 18 ha headwater lake in northern ...

Journal of Limnology, 2014 The metacommunity perspective appears as an appropriate conceptual framework to make ecology more predictive. It is particularly relevant to limnology, where exchanges of organisms and nutrients affect community and ecosystem properties from the local to

Experimental salt marsh islands: a model system for novel metacommunity experiments [PDF]
, 2017 Shallow tidal coasts are characterised by shifting tidal flats and emerging or eroding islands above the high tide line. Salt marsh vegetation colonising new habitats distant from existing marshes are an ideal model to investigate metacommunity theory ...

ZooKeys, 2011 Environmental variability is the main driver for the variation of biological characteristics (life-history traits) of species. Therefore, life-history traits are particularly suited to identify mechanistic linkages between environmental variability and ...

Ecosphere, 2021 DNA metabarcoding has become a powerful technique for identifying the species present in a bulk environmental sample. The application of DNA metabarcoding to wildlife diet analysis is a particularly promising tool for exploring trophic interactions.

Within-host transmission strategies of transovarial, feminizing parasites of Gammarus duebeni [PDF]
, 1998 The amphipod Gammarus duebeni harbours several species of vertically transmitted, feminizing microsporidian parasites. G. duebeni were collected from 3 localities in the UK. Animals from Budle Bay, Northumberland, were infected with Octosporea effeminans,

Environmental species sorting dominates forest‐bird community assembly across scales
Journal of Animal Ecology, 2012 SummaryEnvironmental species sorting and dispersal are seen as key factors in community assembly, but their relative importance and scale dependence remain uncertain, as the extent to which communities are consistently assembled throughout their biomes.To address these issues, we analysed bird metacommunity structure in a 1200‐km2forested landscape ...

Expanded cardboard waste sorting and occupational exposure to microbial species
Waste Management, 2019 Member states of the European Union have to maximize recycling. The current, Danish cardboard recycling system can be improved by increasing the kinds of cardboard products that can be recycled to include e.g. used beverage cartons and pizza boxes (i.e. an expanded cardboard fraction (ECF)).
