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

Ecology and Evolution, Volume 11, Issue 24, Page 17593-17603, December 2021., 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.

Adding large woody material into a headwater stream has immediate benefits for macroinvertebrate community structure and function

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 4, Page 930-947, April 2021., 2021
Abstract Hydromorphological rehabilitation through installing large woody material (LWM) is increasingly being used to reverse degradation of stream ecosystems. There have been many criticisms of stream rehabilitation projects, because many have not met their goals and many others have not been monitored well enough to assess whether their goals were ...

Strong impacts of signal crayfish invasion on upland stream fish and invertebrate communities

Freshwater Biology, Volume 66, Issue 2, Page 223-240, February 2021., 2021
Abstract Impacts of invasive signal crayfish Pacifastacus leniusculus on native species and ecosystems are widely recognised, but mostly through small‐scale studies and laboratory experiments that may not always reflect impacts in nature. Recorded effects of signal crayfish on fish populations are equivocal.

DIFFERENTIATION OF SOME SIMILAR SPECIES OF THE SUBFAMILY TROCHETINAE (HIRUDINIDA: ERPOBDELLIDAE) [PDF]

Ecologica Montenegrina, 2015
Some species of the subfamily Trochetinae Perrier, 1897 are very similar in the external morphology. In this paper we showed that characteristics of the reproductive system can be used as unmistakable features for the determination of the similar species.

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

Leeches from Chiapas, Mexico, with a New Species ofErpobdella(Hirudinida: Erpobdellidae)

American Museum Novitates, 2018
ABSTRACT Freshwater leeches were collected from Chiapas, Mexico. Among these collections and prior records, a total of nine species were found, comprising six genera and four families. One species, Diestecostoma octannulata, represents a new record for Mexico and two species, Helobdella elongata and H.

Dina crnogorensis sp. nov. (Annelida, Hirudinea: Erpobdellidae) – a new leech species from Montenegro

Ecologica Montenegrina, 2022
A yellowish spotted and medium-sized new leech of the family Erpobdellidae with a typical annulation of the genus Dina was found in a spring in the northeastern Montenegro. In the present study, we used an integrative taxonomic approach that combines morphological and DNA barcoding data to describe a new species, Dina crnogorensis sp.

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 ...

From subsidies to stressors: Positively skewed ecological gradients alter biological responses to nutrients in streams

Ecological Applications, Volume 35, Issue 1, January 2025.
Abstract Subsidy–stress gradients offer a useful framework for understanding ecological responses to perturbation and may help inform ecological metrics in highly modified systems. Historic, region‐wide shifts from bottomland hardwood forest to row crop agriculture can cause positively skewed impact gradients in alluvial plain ecoregions, resulting in ...

A dataset of individual wet weights of benthic macroinvertebrates

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common
