Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

(Table 2) Vertical distribution of pelagic polychaetes in Kuril-Kamchatka Trench plankton on 29-30 August 1966

, 1969
Vertical distribution patterns of four mass species of pelagic polychaetes (with separate consideration of the adult, juvenile and larval stages) in plankton of the Kuril-Kamchatka region from the surface to depth of 7000 m are analyzed.

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Intraspecific density effect on growth of Marphysa “sp.” Juveniles

Scientia Marina, 2021
There is growing demand for the territorial tube-building genus Marphysa (Eunicidae: Polychaete), commonly known in Portugal as “goose”, for use as fishing bait, and it is being harvested all around the world for that purpose.

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

First records of polychaetes new to Egyptian Mediterranean waters

Oceanologia, 2013
Nineteen benthic polychaete species were recorded for the first time inthe intertidal zone of the Alexandria coast, south-eastern Mediterranean Sea. They belong toSyllidae (7 species), Hesionidae (3 species), Serpulidae (2 species) and7 other families ...

Unraveling the phylogeny of Chaetopteridae (Annelida) through mitochondrial genome analysis

Frontiers in Marine Science
Mitochondrial genomes serve as valuable markers for phylogenetic and evolutionary studies across diverse invertebrate taxa, but their application within Annelida remains limited.

Polychaetes and allies of Lizard Island

Zootaxa, 2015
This Special Volume of Zootaxa has had a long gestation! Way back in 2011, Pat Hutchings was approached by Anne Hoggett, one of the Co-Directors of Lizard Island Research Station which is a facility of the Australian Museum, with the concept of running a polychaete workshop at Lizard Island.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...
