Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Habitat filtering determines spatial variation of macroinvertebrate community traits in northern headwater streams

, 2013
Although our knowledge of the spatial distribution of stream organisms has been increasing rapidly in the last decades, there is still little consensus about trait-based variability of macroinvertebrate communities within and between catchments in near ...

Evaluation of some physicochemical parameters and benthic macroinvertebrates of Ikere Gorge Reservoir in Oyo State, Nigeria

Journal of Applied Sciences and Environmental Management, 2017
The physico-chemical parameters and benthic macroinvertebrates of Ikere Gorge Reservoir were studied to assess the impact of anthropogenic activities on this man-made lake by collecting surface water and benthic samples. Physico-chemical parameters were

Testing a method for quantifying structural redundancy in ecological communities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In ecological communities, some taxa contribute to ecosystem functioning in highly similar ways. When numerous taxa within a community contribute similarly, this might suggest a degree of functional redundancy, where the loss of one species may not impair ecosystem ...

The comparison of macroinvertebrates and diatoms as two biotic indices of water pollution [PDF]

, 1992
The value of macroinvertebrates and diatom communities as monitors of water quality was studied at 25 sites in the North East of England. The aim was to compare and contrast the two methods on their benefits as environmental quality indicators.

Characteristics of benthic macroinvertebrate communities in a typical high sediment-loaded river in China

Journal of Freshwater Ecology
To date, the knowledge of benthic macroinvertebrates in the upper reaches of the Jinsha River remains quite limited compared to other rivers in China due to the difficulty of sampling and special geographical environment.

Ecological Health Assessment of the Vam Co River System, Vietnam: Insights from Benthic Macroinvertebrates and Environmental Changes [PDF]

Nature Environment and Pollution Technology
This study investigated the relationships between benthic macroinvertebrates and environmental variables in the Vam Co River system in southern Vietnam. Field surveys were conducted four times from May to November 2023 to evaluate seasonal variations in ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.
