Sediment Core DNA-Metabarcoding and Chitinous Remain Identification: Integrating Complementary Methods to Characterise Chironomidae Biodiversity in Lake Sediment Archives. [PDF]
Mol Ecol ResourABSTRACT Chironomidae, so‐called non‐biting midges, are considered key bioindicators of aquatic ecosystem variability. Data derived from morphologically identifying their chitinous remains in sediments document chironomid larvae assemblages, which are studied to reconstruct ecosystem changes over time.

Knowledge and Management of Aquatic Ecosystems, 2019 Salinity is one of the most important factors in aquatic ecosystems, but its filtering role in the Diptera community species composition is still poorly studied. This issue was studied in the diverse Crimean water bodies.

Brazilian Journal of Biology, 2010 The aim of this work was to evaluate whether diel vertical migration of microcrustaceans from Lake Monte Alegre is related to invertebrate predators, namely larvae of Chaoborus brasiliensis. The hypothesis tested in the experiments was that the migratory

Neotropical IchthyologyWe analyzed the diet of Triportheus curtus in Lake Amapá on the Acre River (AC - Brazil), during three distinct phases of the hydrological cycle (pre-flooding, flooding, and post-flooding stages).

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT Cage aquaculture is expanding in Lake Victoria to meet increasing fish demand, yet ecological impacts remain a concern. This study assessed the effects of cage aquaculture on water quality and the abundance and diversity of pelagic and benthic macroinvertebrates at Anyanga Beach, Lake Victoria, Kenya.

The Aggregation of Fish in the Metalimnion Constrains Zooplankton Diel Vertical Migration
Freshwater Biology, Volume 71, Issue 6, June 2026.ABSTRACT The role of fish predation in zooplankton diel vertical migration (DVM) is well established, where zooplankton move to deep waters during the day—to hide from visual predators in surface layers—and return to the epilimnion at night (i.e., ‘normal’ DVM), to feed on phytoplankton.

Acta Scientiarum: Biological Sciences, 2008 Inúmeros trabalhos têm mostrado que a larva de Chaoborus desenvolve migração vertical diária, buscando evitar a predação por peixes, e que a amplitude da migração vertical cresce com o estágio larval. Neste estudo, monitorou-se a distribuição vertical de

Biotropica, Volume 58, Issue 2, March 2026.Amphibian populations worldwide face threats from emerging infectious diseases. We screened frog‐biting midges (Corethrella spp.) from Central and South America for Batrachochytrium dendrobatidis, Ranaviruses, and Trypanosoma spp. using qPCR. All three pathogens were detected, indicating that Corethrella may act as vectors and represent promising tools

First finding of larvae of Chaoborus crystallinus (Diptera, Chaoboridae) in Serbia [PDF]
Archives of Biological Sciences, 2006 lakes, and wells. They can be found near the surface of aquatic ecosystems, but also at considerable depths on the muddy bottoms of lakes and wells (M e l l a n b y, 1968). Certain species can live buried several centimeters in mud. Their dissemination is of a local nature.
