The potential of aquatic bloodfeeding and nonbloodfeeding leeches as a tool for iDNA characterisation. [PDF]

Mol Ecol Resour, 2022
Abstract Leeches play important roles in food webs due to their abundance, diversity and feeding habits. Studies using invertebrate‐derived DNA (iDNA) extracted from leech gut contents to target vertebrate DNA have focused on the Indo‐Pacific region and mainly leveraged the leech family Haemadipsidae, composed of bloodfeeding terrestrial leeches, while

Sucking of human blood by Placobdella costata (O. F. Müller, 1846) (Hirudinida: Glossiphoniidae): Case study with notes on body form. [PDF]

Ecol Evol, 2021
In our paper, four events of blood sucking on human by juvenile and adult specimens of Placobdella costata were described. We presented with a new data of juvenile specimens' body form and considered information about the potential role of mammals as hosts and dispersion vector of this leech.

The Role of Artificial Lakes Located in Forests in the Context of Small Retention, Biodiversity and Climatic Changes-Evidence From Southern Poland. [PDF]

Ecol Evol
The model of plant associations showed the occurrence of 24 species of plants within nine plant assemblages in the Phragmitetea and Potametea classes of associations. Despite human activities, lake condition, as assessed by the ESMI index or the biocenotic diversity indices, is good.

Molecular Insights Into the Sensory Adaption of the Cave-Dwelling Leech Sinospelaeobdella wulingensis to the Karst Cave Environment. [PDF]

Ecol Evol
We conducted a transcriptome analysis on the cave‐dwelling land leech Sinospelaeobdella wulingensis. Piezos, TRPs, and iGluRs may have roles in mechanosensory and chemosensory systems of this leech. Similar gene expression profiles in winter and summer samples imply a stable physiological status of S.

Neglected symbionts and other metazoan invertebrates associated with molluscs from Africa's largest lake: Diversity, biotic interactions and bioindication

Freshwater Biology, Volume 67, Issue 12, Page 2089-2099, December 2022., 2022
Abstract Freshwater molluscs are hosts for diverse metazoan symbionts. However, apart from the digenean helminths, symbionts of molluscs are underreported worldwide. Therefore, this study focused on the diversity of oligochaetes, leeches, mites, insect larvae and nematodes associated with gastropods and bivalves from Lake Victoria, East Africa. Overall,

Habitat availability determines food chain length and interaction strength in food webs of a large lowland river

River Research and Applications, Volume 38, Issue 2, Page 323-333, February 2022., 2022
Abstract Many large rivers used for navigation have lost their hydromorphological heterogeneity, which has led to the widespread loss of native biodiversity and the concurrent establishment of non‐native communities. While the effects on biodiversity are well‐described, we know little about how the loss of natural habitats and the restructuring of ...

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.
