Exploring Barbronia species diversity and phylogenetic relationship within Suborder Erpobdelliformes (Clitellata: Annelida) [PDF]

PeerJ
Background Barbronia, a genus of freshwater macrophagous leeches, belongs to Erpobdelliformes (Salifidae: Clitellata: Annelida), and B. weberi, a well-known leech within this genus, has a worldwide distribution. However, the systematics of Barbronia have

A fine-scale phylogenetic assessment of digenean trematodes in central Alberta reveals we have yet to uncover their total diversity. [PDF]

Ecol Evol, 2019
This manuscript represents a large, single, collective examination of larval trematodes from snail hosts, using molecular markers and phylogenetic methods. We contribute 1,091 mitochondrial sequences (cox1 and nad1) that represent 79 species from 23 genera and eight families.

Behavioral variation according to feeding organ diversification in glossiphoniid leeches (Phylum: Annelida). [PDF]

Sci Rep, 2021
Adaptive radiation is a phenomenon in which various organs are diversified morphologically or functionally as animals adapt to environmental inputs. Leeches exhibit a variety of ingestion behaviors and morphologically diverse ingestion organs.

First Records of Potamic Leech Fauna of Eastern Siberia, Russia

Dataset Papers in Science, Volume 2013, Issue 1, 2013., 2013
We studied the fauna of leech and leech‐like species inhabiting main water streams of Eastern Siberia and its tributaries, which are attributed to Lake Baikal basin and Lena River basin. Here we present their list for the first time. This study was mainly aimed for free‐living parasitic and carnivorous leeches whereas piscine parasites were not ...

Phylogeny and revision of Erpobdelliformes (Annelida, Arhynchobdellida) from Mexico based on nuclear and mithochondrial gene sequences. Filogenia y revisión de los Erpobdelliformes (Annelida, Arhynchobdellida) de México, con base en secuencias de ADN nuclear y mitocondrial

Revista Mexicana de Biodiversidad, 2005
The phylogenetic relationships of the suborder Erpobdelliformes, a group of non-sanguivorous leeches, were investigated with the use of mitochondrial cytochrome c oxidase subunit I, mitochondrial 12S rDNA and nuclear 18S rDNA.

KF‐metaweb: A trophic metaweb of freshwater ecosystems of South Korea

Global Ecology and Biogeography, Volume 33, Issue 7, July 2024.
Abstract Motivation The metaweb is a dictionary of nodes and their potential interactions developed for a particular region, focusing on a particular type of ecosystem. Based on the local biodiversity information at different spatial and temporal scales, the regional metaweb can be easily decomposed into local webs.

Food web structures of irrigated rice fields estimated from carbon and nitrogen stable isotopes: Special reference to the role of filamentous green algae as a food resource of aquatic consumers

Ecological Research, Volume 39, Issue 3, Page 318-329, May 2024.
We examined aquatic food web structures in two adjacent rice fields in northeastern Japan using carbon and nitrogen stable isotope ratios. δ13C‐based isotopic mixing model estimated that the majority of herbivores and omnivores, as well as several carnivorous taxa, assimilated carbon derived from filamentous green algae (contributions to carbon ...
