The effects of loose, firm, fine, and coarse substrates on the movement of the red flour beetle
The study focused on the impact of substrate roughness on movement properties, utilizing the red flour beetle as a model organism. Findings revealed significant variations in movement behavior between rough and smooth substrates, with beetles traveling longer distances on smooth surfaces compared to sandpaper and loose sand.

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.

A phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824)
Abstract In spite of their important roles in many ecosystems, data regarding population structure and biogeographic patterns of leeches are scarce. To begin to address this knowledge gap, we herein perform a phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824). A total of 224 M. decora specimens were collected

Appearance and localization of acetylcholinesterase in embryos of the leech Helobdella triserialis [PDF]
The appearance and localization of acetylcholinesterase (AchE) were studied during embryonic development of the leech Helobdella triserialis. Use of a histochemical stain showed that AchE is present in the polar plasms of the uncleaved leech egg. in the course of the first two cleavages, the AchE is transmitted along with the polar plasms mainly to the

A dataset of individual wet weights of benthic macroinvertebrates
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
