Hirudinea (Annelida) Fauna of Some Wetlands in Bingöl Province

Türkiye Parazitoloji Dergisi, 2022
Objective:Leeches are important and reliable indicators of water quality and biodiversity in the ecosystem, so the presence of specific leech species is often closely related to basic water conditions and the presence of certain animals.

Assessing the impact of the threatened crucian carp (Carassius carassius) on pond invertebrate diversity: A comparison of conventional and molecular tools

Molecular Ecology, Volume 30, Issue 13, Page 3252-3269, July 2021., 2021
Abstract Fishes stocked for recreation and angling can damage freshwater habitats and negatively impact biodiversity. The pond‐associated crucian carp (Carassius carassius) is rare across Europe and is stocked for conservation management in England, but its impacts on pond biota are understudied.

Eutrophication induces shifts in the trophic position of invertebrates in aquatic food webs

Ecology, Volume 102, Issue 3, March 2021., 2021
Abstract Changes in the ecological stoichiometry of primary producers may have considerable implications for energy and matter transfer in food webs. We hypothesized that nutrient enrichment shifts the trophic position of omnivores towards herbivory, as the nutritional quality of primary producers increases.

Anthropogenic litter is a novel habitat for aquatic macroinvertebrates in urban rivers

Freshwater Biology, Volume 66, Issue 3, Page 524-534, March 2021., 2021
Abstract Anthropogenic litter (solid manufactured waste) is an understudied but pervasive element of river systems worldwide. Its physical structure generally differs from natural substrates, such as gravel and cobbles (hereafter rocks). Consequently, anthropogenic litter could influence ecological communities in urban rivers by providing novel ...

Leeches as Sensor-bioindicators of River Contamination by PCBs

Sensors, 2009
The aim of the study was to evaluate the use of leeches of the genus Erpobdella as a means of assessing polychlorinated biphenyl contamination of watercourses. The River Skalice, heavily contaminated with PCBs, was selected as a model.

Phylogenomic analyses reveal a Palaeozoic radiation and support a freshwater origin for clitellate annelids

Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020
Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...

Predators and resources influence phosphorus transfer along an invertebrate food web through changes in prey behaviour. [PDF]

PLoS ONE, 2013
Predators play a fundamental role in prey trophic behaviour, with indirect consequences for species coexistence and ecosystem functioning. Resource quality and availability also influence prey trophic behaviour, with potential effects on predator-prey ...
