Freshwater macroinvertebrate traits assessment as complementary to taxonomic information for mining impact detection in the northern Peruvian Andes

Diversity and Distributions, Volume 28, Issue 8, Page 1582-1596, August 2022., 2022
Abstract Aim We studied the distribution of freshwater macroinvertebrate taxa and traits to distinguish ecological gradients among the mining‐controlled and natural headwaters, and rural and urban economic activity influences. Location In 2016’s dry season, macroinvertebrate samples were collected at 40 locations in the Mashcon watershed, northern ...

Environmental DNA of preservative ethanol performed better than water samples in detecting macroinvertebrate diversity using metabarcoding

Diversity and Distributions, Volume 27, Issue 10, Page 1989-2002, October 2021., 2021
Abstract Aim High‐throughput pipelines supported by eDNA metabarcoding have been applied in various freshwater ecosystems. Both eDNA in ethanol (EtOH) samples (ES‐eDNA) and in water samples (WS‐eDNA) can provide comprehensive classification lists with good taxonomic resolution and coverage for determining freshwater biodiversity and biomonitoring. But,

The activity of hydrolytic enzymes in the digestive system of Acanthobdellida, Branchiobdellida and Hirudinida (Annelida, Clitellata) – considerations on similarity and phylogeny

The European Zoological Journal, 2021
Activities of nineteen hydrolases were measured in the digestive systems of predatory and blood-feeding true leeches (Hirudinida) and their closest relatives, Branchiobdellida and Acanthobdellida.

Phylogenomic analyses reveal a Palaeozoic radiation and support a freshwater origin for clitellate annelids

Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020
Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...

Registros de sanguijuelas de Costa Rica y clave para la identificación de las especies con redescripción de Cylicobdella costaricae

Revista Mexicana de Biodiversidad, 2015
En contraste con los enormes esfuerzos realizados por caracterizar la fauna y flora de Costa Rica, con excepción de algunos registros aislados, muy poco se sabe sobre las sanguijuelas (Annelida: Clitellata) en este país.

First Record of <i>Mimobdella japonica</i> (Hirudinida: Arhynchobdellida: Salifidae) from Hachijojima Island, Izu Islands, Japan, with a Comment on the Genetic Diversity of the Species

Holotype redescription of Mimobdella japonica (Hirudinida, Arhynchobdellida, Erpobdelliformes) and taxonomic status of the genus Mimobdella., 2016
Mimobdella japonica Blanchard, 1897, the type species of the genus Mimobdella Blanchard, 1897, is redescribed based on the holotype. This species is characterized by the following characteristics: mid-body somites novem-annulate, two post-anal annuli, male gonopore in XI/XII, female gonopore in XII/XIII, 9 annuli (one full somite) between gonopores ...

Study on Freshwater Macroinvertebrates of Some Tanzanian Rivers as a Basis for Developing Biomonitoring Index for Assessing Pollution in Tropical African Regions

Journal of Ecosystems, Volume 2014, Issue 1, 2014., 2014
Macroinvertebrates and physicochemical parameters were assessed at 15 sites along five rivers in Kilimanjaro region, Tanzania, with the aim of understanding their ecological status and setting a base to the development of a biological index for tropical regions.

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

Effects of weir‐induced habitat fragmentation on the diversity and community composition of benthic macroinvertebrates in an agricultural stream

Entomological Research, Volume 54, Issue 9, September 2024.
Abstract This research delves into the effects of weir‐induced habitat fragmentation on the diversity and structure of benthic macroinvertebrate communities in Topyeong Stream in the Republic of Korea. Through comprehensive zonation, environmental assessments and analyses of macroinvertebrate populations, the study brings to light the significant ...
