Patterns of Autonomous and Conditional Neural Specification for the Brain and Ventral Nerve Cord in Annelida

Evolution &Development, Volume 28, Issue 3, September 2026.
Diagrams of blastomere isolations in Capitella teleta and Platynereis dumerilii showing autonomous head neural tissue (from 1q) and trunk neural tissue (from 2d) as well as a decoupling of D–V axis formation from trunk neural tissue in annelids. ABSTRACT Evolution of central nervous systems is a long‐debated topic.

Hirudinea (Annelida) Fauna of Some Wetlands in Bingöl Province

Türkiye Parazitoloji Dergisi, 2022
Objective:Leeches are important and reliable indicators of water quality and biodiversity in the ecosystem, so the presence of specific leech species is often closely related to basic water conditions and the presence of certain animals.

First Record of Bioluminescence in a Sipunculan Worm

Frontiers in Marine Science, 2021
During a search for bioluminescent marine annelids around the island of Carrie Bow Cay, Belize, we discovered bioluminescence in the sipunculan worm Nephasoma pellucidum. The identification of N. pellucidum was verified by DNA barcoding of ∼650 bp of the

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, Volume 2026, Issue 8, August 2026.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Stable isotopes reveal that gelatinous zooplankton diets group by taxonomy and feeding traits in a coastal upwelling system

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Gelatinous zooplankton are abundant in marine ecosystems, yet their trophic roles and functional diversity in food webs have only recently gained attention. Gelatinous zooplankton taxa including hydromedusae, ctenophores, siphonophores, chaetognaths, and pelagic tunicates span multiple phyla and are often grouped taxonomically, but trait‐based

Limited connectivity of zooplankton communities across the Labrador Front: role of physical oceanography, insights from individual motility

Oikos, Volume 2026, Issue 8, August 2026.
Near the western margin of the highly productive Labrador Sea, the Labrador Current creates a large and steep oceanographic front between the Arctic‐origin shelf waters and the Atlantic offshore waters (i.e. the Labrador Front), presumably segregating or accumulating plankton communities.

New systematic results based on chaetal hard structures in Mesochaetopterus (Polychaeta)

Scientia Marina, 2006
Two kinds of chaetal hard structures have been analysed within the genus Mesochaetopterus (Chaetopteridae, Polychaeta): the specialised chaetae of the fourth segment of the anterior part of the body (i.e. the A4 segment) and the uncinal plates present on

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

First record of the exotic earthworm Metaphire bahli (Gates, 1945) (Oligochaeta: Megascolecidae) from India [PDF]

Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2019
The occurrence of the exotic earthworm species Metaphire bahli (Gates, 1945) of the family Megascolecidae is recorded for the first time from India. Specimens were collected from the Alappuzha District of Kerala State.
