NUEVOS PECES DULCEACUICOLAS HOSPEDEROS DE LARVAS DE GORDIACEOS (NEMATOMORPHA) EN EL SUR DE CHILE

open access: yes, 2021
Nematomorpha Vejdovsky, 1886 includes most of its species in the taxon Gordiida, presenting a freshwater free-living adult and a parasitic larval stage that live in some aquatic invertebrates, amphibians and fish. Present results documented morphological

The Evolution and Ecology of Host Manipulation in Helminth Parasites: A Phylogenetic Meta‐Analysis

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Host manipulation by parasites is wide spread but the conditions shaping it remain unclear. In a phylogenetic meta‐analysis on trophically transmitted helminths, manipulation reliably increased host predation susceptibility to predation in mature parasites, while the effect of immature parasites remained unclear.

Riparian Bryophytes: An Overlooked Yet Important Habitat for Aquatic Macroinvertebrates in Interior Pacific Northwest (USA) Salmonid‐Bearing Streams

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We investigated riparian bryophytes as habitat for aquatic invertebrates in an interior Pacific Northwest (PNW) salmonid stream system. Our results demonstrate that bryophytes are highly productive habitat for aquatic invertebrates in interior Pacific Northwest salmonid streams.

Revision of the genus Beatogordius (Gordiida, Nematomorpha): II. South american species with description of two new species

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
Seven species of Beatogordius (Nematomorpha) have been reported from South America. A reinvestigation could not reproduce a number of determinations indicated in the literature. B. deshayesi has been a misinterpretation and the status of B.

Structural Basis of GABAB Receptor Activation during Evolution

open access: yesAdvanced Science, Volume 12, Issue 37, October 6, 2025.
This study explores the structural and functional mechanisms of the drosophila GABAB receptor, a key role in neurotransmission. Using cryo‐EM, the research reveals how the receptor's activation differs from its human counterpart, highlighting unique evolutionary features.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

New hairworm (Nematomorpha, Gordiida) species described from the Arizona Madrean Sky Islands

open access: yesZooKeys, 2018
Gordiids, or freshwater hairworms, are members of the phylum Nematomorpha that use terrestrial definitive hosts (arthropods) and live as adults in rivers, lakes, or streams.

Advancing aquatic biodiversity assessments of invertebrates using eDNA metabarcoding: A systematic evaluation of primers for marine and freshwater communities

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2408-2430, October 2025.
Abstract Invertebrate richness and community composition are key indicators of aquatic ecosystem health. Compared with morphotaxonomy‐based survey methods, DNA metabarcoding is a highly efficient and scalable biomonitoring approach that has become increasingly used in invertebrate surveys.
