Complex effects of acidification, habitat properties and fish stock on littoral macroinvertebrate assemblages in montane standing waters

open access: yesJournal of Limnology, 2022
Littoral macroinvertebrates in acidified waterbodies are affected by the interaction of acidification and local environmental conditions. Understanding the interplay of these factors in the structuring of communities is essential for interpreting ...

Ingestion and Chronic Effects of Car Tire Tread Particles on Freshwater Benthic Macroinvertebrates

open access: yesEnvironmental Science and Technology, 2018
Micronized particles released from car tires have been found to contribute substantially to microplastic pollution, triggering the need to evaluate their effects on biota.

Beta diversity of macroinvertebrate assemblages associated with aquatic macrophytes in shallow lakes within a tropical floodplain-dammed river [PDF]

open access: yesActa Limnologica Brasiliensia
: Aims We assessed the beta diversity of macroinvertebrates associated with aquatic macrophytes in a dam-regulated river floodplain. We tested two hypotheses: (1) macroinvertebrates associated with aquatic macrophytes have higher beta diversity (higher ...

The effect of urban point source contamination on microplastic levels in water and organisms in a cold‐water stream

open access: yesLimnology and Oceanography Letters, 2020
We examined the influence of point and nonpoint source contamination on microplastic (MP) levels in water, macroinvertebrates, and trout in a small, cold‐water stream in western Wisconsin, U.S.A.

A new substrate for sampling deep river macroinvertebrates [PDF]

open access: yes, 2009
We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting ...

Catastrophic effects of sand mining on macroinvertebrates in a large shallow lake with implications for management.

open access: yesScience of the Total Environment, 2019
Sand mining is a human activity that is increasing in inland waters and has profound effects on entire aquatic ecosystems. However, current knowledge of the effects of sand mining on freshwater lake ecosystems remains limited, especially for biotic ...

Macroinvertebrates associated with Guzmania mitis L.B. Sm. (Bromeliaceae) in two fragments of oak grove

open access: yesColombia Forestal, 2013
The composition and abundance of macroinvertebrates associated with the terrestrial bromeliad Guzmania mitis in two fragments of oak grove with different conservation status in Arcabuco, Boyacá were studied. The study aimed to establish whether there are

Building a local reference library for metabarcoding survey of lake macrobenthos: oligochaetes and chironomids from Lake Maggiore

open access: yesAdvances in Oceanography and Limnology, 2022
This study represents a first reference database of genetic diversity of macroinvertebrates for a barcoding marker for Lake Maggiore, focusing on the two dominant groups of the littoral benthic fauna (chironomids and oligochaetes), commonly used for ...
