A dataset of individual wet weights of benthic macroinvertebrates

open access: yesLimnology 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

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

open access: yes, 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.
