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.

Testing the spatial and temporal framework of speciation in an ancient lake species flock: the leech genus Dina (Hirudinea: Erpobdellidae) in Lake Ohrid [PDF]

Biogeosciences, 2010
Ancient Lake Ohrid on the Balkan Peninsula is considered to be the oldest ancient lake in Europe with a suggested Plio-/Pleistocene age. Its exact geological age, however, remains unknown.

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.

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 ...

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

Stream Quality and Benthic Macroinvertebrate Diversity in the Badeye Area, Logone Occidental Province, Southwestern Chad

International Journal of Ecology, Volume 2024, Issue 1, 2024.
The aim of this study of benthic macroinvertebrates in the southwestern canton of Badeye in Chad was to analyze the community structure in relation to the physicochemical quality of water in the Man baptem tributary. A total of 4,012 benthic macroinvertebrates were identified and counted in 38 families.
