Hirudinea (Annelida) Fauna of Some Wetlands in Bingöl Province

open access: yesTürkiye 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

open access: yesMolecular 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

open access: yesEcology, 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

open access: yesFreshwater 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 ...

Calhoun et al. HOW parasite exposure and time drive infection how parasite exposure and time interact to determine Australapatemon burti (Trematoda: Digenea) infections in second intermediate host (Erpobdella microstoma) (Hirudinea: Erpodellidae).

open access: yesExperimental parasitology, 2020
Australapatemon spp. are cosmopolitan trematodes that infect freshwater snails, aquatic leeches, and birds. Despite their broad geographic distribution, relatively little is known about interactions between Australapatemon spp.

Natural occurrence of an experimental developmental phenotype in the leech Erpobdella punctata (Leidy 1870) (Annelida: Clitellata: Hirudinea)

open access: yes, 2020
In the embryonic blast cells of leeches, segmental identity is conferred in a cell-intrinsic manner (i.e., with temporal rather than spatial signals), at or shortly after the birth of the cell.
