Diagnosis of the Condition of Aquatic Ecosystems Using a Partial Assessment of Ecological and Trophic States: An Example of Small Lakes in Northern Poland

Limnological Review
The current state of aquatic ecosystems was assessed for lakes in two river–lake systems: Święta Struga (Święte and Ocypelek) and Kałębnica (Czarne Południowe and Kałębie).

A microsensor‐based method for measuring respiration of individual nematodes

Methods in Ecology and Evolution, 2021
Meiofauna (invertebrates that pass through a 1‐mm mesh sieve, but are retained on a 40‐µm mesh) represent the most abundant and diverse animal group on Earth, but empirical evidence of their role in benthic respiration, production and carbon cycling ...

On the ecology of Cletocamptus gomezi Suárez-Morales, Barrera-Moreno & Ciros-Pérez 2013 (Crustacea, Copepoda, Harpacticoida) micro-endemic to Lake Alchichica, Central Mexico

Journal of Limnology, 2014
Cletocamptus gomezi Suárez-Morales, Barrera-Moreno & Ciros-Pérez (2013) is a recently described new species of meiobenthic Harpacticoida copepod, micro-endemic to Lake Alchichica, Puebla, Central Mexico. Cletocamptus gomezi lives in saline water (K25

Diversity and distribution of benthic invertebrates dwelling rivers of the Kruger National Park, South Africa

Koedoe: African Protected Area Conservation and Science, 2022
Meiobenthos (or meiofauna) are microscopic invertebrates that inhabit biofilms and interstitial spaces in rivers. They are diverse and extremely abundant, and they perform essential ecological functions by linking microbial production to higher trophic ...

Taxonomy assignment approach determines the efficiency of identification of OTUs in marine nematodes [PDF]

Royal Society Open Science, 2017
Precision and reliability of barcode-based biodiversity assessment can be affected at several steps during acquisition and analysis of data. Identification of operational taxonomic units (OTUs) is one of the crucial steps in the process and can be ...

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

Two new meiofaunal species of Trilobodrilus (Dinophilidae, Annelida) from California, USA

European Journal of Taxonomy, 2018
We describe two new species of the annelid genus Trilobodrilus Remane, 1925 (Dinophilidae Verill, 1892) from an intertidal and a subtidal location in San Diego, California. These two species show morphological and molecular divergences between each other

Faunal Composition of the Sumisu Caldera Hydrothermal Vent Field as a Key Baseline for Conservation in Light of Deep‐Sea Mining

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 11, November 2024.
ABSTRACT Hydrothermal vents are biodiversity hotspots on the deep seafloor powered by chemosynthetic primary production, inhabited by a specially adapted fauna whose composition varies between regions. Sumisu Caldera, located approximately 500 km south of Tokyo, hosts a hot vent with an unusual species composition among the Izu–Ogasawara Arc sites and ...

Contribution of soft-bodied meiofaunal taxa to Italian marine biodiversity

The European Zoological Journal, 2020
Meiofauna includes an astonishing diversity of organisms, whose census is far from being complete. Most classic ecological studies have focused on hard-bodied Ecdysozoan taxa (notably Copepoda and Nematoda), whose cuticle allows determination at species ...

Migrating ripples create streambed heterogeneity altering microbial diversity and metabolic activity

Limnology and Oceanography, Volume 69, Issue 8, Page 1882-1899, August 2024.
Abstract Sandy sediments of lowland streams are typically transported at low flow in the form of migrating ripples. In these bedforms, microbial communities spanning all trophic guilds (heterotrophic bacteria, fungi, photoautotrophic and phagotrophic protists) are exposed to highly frequent moving–resting cycles of sediment grains.
