Gaps and Data Ambiguities in DNA Reference Libraries: A Limiting Factor for Molecular-Based Biodiversity Assessments Using Annelids as a Case Study. [PDF]

Ecol Evol
Regional DNA reference libraries are crucial for molecular biodiversity assessments, yet they remain incomplete, limiting their effectiveness. Using annelids from the Arabian Peninsula as a case study, we identified considerable gaps in species coverage and minimal representation in public databases.

Molecular phylogeny of the Lecudinoidea (Apicomplexa): A major group of marine gregarines with diverse shapes, movements and hosts. [PDF]

J Eukaryot Microbiol
Abstract Gregarine apicomplexans are ubiquitous endosymbionts of invertebrate hosts. Despite their ecological and evolutionary importance, inferences about the phylogenetic relationships of major gregarine groups, such as the Lecudinidae and Urosporidae, have been hindered by vague taxonomic definitions and limited molecular and morphological data.

Acid Sulfate Soils and Their Pathways of Impact: A Swedish Case Study. [PDF]

Ecol Evol
This study is an initial report on the situation in an estuary affected by acidic sulfate soils in an area of Sweden where this has not been investigated before. The study clearly states that metals and acidic effluents from the agricultural acidic sulfate soil are transported via riverine water to the adjacent estuary where metals accumulate in the ...

Osteology of the Feeding Apparatus of Chilean Flamingo Phoenicopterus chilensis (Aves: Phoenicopteridae). [PDF]

J Morphol
1. The skull features a broad, dorsoventrally flattened frontal region articulating with an elongated upper jaw that is complemented by the mandible's downward bend along its proximal half. 2. The low mechanical advantage in the mandible is attributed to the reduced and shallow insertion areas of the adductor muscles, which are positioned close to the ...

A Comprehensive DNA Barcode Reference Library for the Macroinvertebrates of Scottish Seagrass Beds Using Oxford Nanopore Flongle Flowcells. [PDF]

Ecol Evol
In this study we use ONT Flongle Flowcells to produced DNA barcodes for 146 seagrass associated marine invertebrate OTUs collected from four seagrass beds in Scotland, targeting COI and 18S V4 regions. We generate the first DNA barcode reference library for seagrass beds in Scotland to support future biomonitoring of these priority habitats.

Redescriptions of four nereidid species (Annelida: Phyllodocida: Nereididae) from the Atlantic Ocean described by Aaron Louis Treadwell

Revista Mexicana de Biodiversidad, 2022
Aaron Louis Treadwell proposed a large number of new taxa, and several of them are regarded as synonyms. Treadwell proposed 32 new species in the family Nereididae, and a few of them have been re-evaluated.

From the sea to aquafeed: A perspective overview

Reviews in Aquaculture, Volume 15, Issue 3, Page 1028-1057, June 2023., 2023
Abstract Aquaculture has been one of the fastest‐growing food production systems sectors for over three decades. With its growth, the demand for alternative, cheaper and high‐quality feed ingredients is also increasing. Innovation investments on providing new functional feed alternatives have yielded several viable alternative raw materials ...

Microcystin-induced oxidative stress in Laeonereis acuta (Polychaeta, Nereididae) [PDF]

Marine Environmental Research, 2008
Oxidative stress induced by microcystins was evaluated in an estuarine worm, Laeonereis acuta (Nereididae). Ten organisms were exposed to lyophilized cells of a toxic Microcystisaeruginosa strain RST9501 ( approximately 2 microg/mL microcystins, MC); 10 were exposed to lyophilized cells of a nontoxic Aphanotece sp. strain RSMan92 and 10 were maintained

A new species of Rullierinereis and new records of Nereididae from sublittoral sandy bottoms off Lanzarote (Canary Islands)

Scientia Marina, 2006
Rullierinereis ancornunezi n. sp., collected from sandy and maërl bottoms from 19-55 m depth around Lanzarote island, is described. The new taxon is characterized by having a reduced or absent upper notopodial ligule in biramous parapodia of chaetigers 3-
