Reproductive morphology and redescriptions of some Neanthes Kinberg, 1865 (Annelida: Nereididae) species from the southeastern Asian seas, with comparative synoptic tables of accepted species

open access: yesThe European Zoological Journal, 2021
Neanthes Kinberg, 1865 is a speciose nereidid genus with some species exhibiting epitoky during the timing of reproduction. The epitokal morphology of males and females has long been agreed to be diagnostic to distinguish species.

First record of growth patterns in a Cambrian annelid

open access: yesRoyal Society Open Science, 2023
Early annelid evolution is mostly known from 13 described species from Cambrian Burgess Shale-type Lagerstätten. We introduce a new exceptionally well-preserved polychaete, Ursactis comosa gen. et sp. nov., from the Burgess Shale (Wuliuan Stage).

Compositional and Functional Microbiome Variation Between Tubes of an Intertidal Polychaete and Surrounding Marine Sediment

open access: yesFrontiers in Marine Science, 2021
The decorator worm Diopatra cuprea, a tube-forming marine polychaete common to intertidal and shallow subtidal waters, modifies habitats it occupies through microreef construction and algal gardening.

Searching for a Home Port in a Polyvectic World: Molecular Analysis and Global Biogeography of the Marine Worm Polydora hoplura (Annelida: Spionidae)

open access: yesBiology, 2023
The spionid polychaete Polydora hoplura Claparède, 1868 is a shell borer widely occurring across the world and considered introduced in many areas. It was originally described in the Gulf of Naples, Italy.

Evaluating restriction enzyme selection for reduced representation sequencing in conservation genomics

open access: yesMolecular Ecology Resources, EarlyView., 2023
Abstract Conservation genomic studies in non‐model organisms generally rely on reduced representation sequencing techniques based on restriction enzymes to identify population structure as well as candidate loci for local adaptation. While the expectation is that the reduced representation of the genome is randomly distributed, the proportion of the ...

Integrative biology of injury in animals

open access: yesBiological Reviews, Volume 98, Issue 1, Page 34-62, February 2023., 2023
ABSTRACT Mechanical injury is a prevalent challenge in the lives of animals with myriad potential consequences for organisms, including reduced fitness and death. Research on animal injury has focused on many aspects, including the frequency and severity of wounding in wild populations, the short‐ and long‐term consequences of injury at different ...

Exotic asphyxiation: interactions between invasive species and hypoxia

open access: yesBiological Reviews, Volume 98, Issue 1, Page 150-167, February 2023., 2023
ABSTRACT Non‐indigenous species (NIS) and hypoxia (<2 mg O2 l−1) can disturb and restructure aquatic communities. Both are heavily influenced by human activities and are intensifying with global change. As these disturbances increase, understanding how they interact to affect native species and systems is essential.

Performance of polychaete assisted sand filters under contrasting nutrient loads in an integrated multi-trophic aquaculture (IMTA) system

open access: yesScientific Reports, 2020
Polychaete assisted sand filters (PASFs) allow to combine a highly efficient retention of particulate organic matter (POM) present in aquaculture effluent water and turn otherwise wasted nutrients into valuable worm biomass, following an integrated multi-

Suitability of compensatory saltmarsh habitat for feeding and diet of multiple estuarine fish species

open access: yesFisheries Management and Ecology, Volume 30, Issue 1, Page 44-55, February 2023., 2023
Abstract Saltmarsh provides essential fish feeding and nursery habitat but has globally declined by 50%. We used a statistical block design to compare fish feeding activity within human‐engineered or “re‐aligned” saltmarsh to established saltmarsh.
