Formation of microplastics by polychaetes (Marphysa sanguinea) inhabiting expanded polystyrene marine debris

open access: yes, 2018
Fragmentation of large plastic debris into smaller particles results in increasing microplastic concentrations in the marine environment. In plastic debris fragmentation processes, the influence of biological factors remains largely unknown, This study ...

Interspecific relations (interactions) between the Black Sea polychaetes

open access: yes, 2000
Possible interactions between the the Black Sea polychaetes are discussed. Some negative interactions (competition, amensalism, predation) are dominant among the populations of the Black Sea polychaetes or essential interrelations between the polychaetes

The DNA barcode, molecular characters for Korean Polychaetes.

open access: yes, 2012
Polychaetes appear as dominant organisms in many of the coastal marine ecosystems, yet understanding of their taxonomy and genetics is limited. Most of the polychaete species have trouble in identification of their species based on the morphological ...

The Role of Life Stages in the Sensitivity of Hediste diversicolor to Nanoplastics: A Case Study with Poly(Methyl)Methacrylate (PMMA)

open access: yesToxics
The presence of plastic particles in oceans has been recognized as a major environmental concern. The decrease in particle size increases their ability to directly interact with biota, with particles in the nanometer size range (nanoplastics—NPs ...

Addressing gaps in the culture of pathogen-free polychaetes as feed in shrimp hatcheries

open access: yes, 2018
One of the factors that contribute to the success of shrimp hatchery operations is the availability of good quality broodstock diets. Polychaetes have been regarded as the best maturation diet for shrimps as they contain essential nutrients requisite for

Polychaetes associated with decaying wood in Térraba mangrove, South Pacific, Costa Rica [PDF]

open access: yes, 2015
The present study shows spatial patterns in the faunal assemblage of decaying wood and sediments, with emphasis on the polychaetes. The survey was executed across a salinity gradient in a tropical mangrove estuary of Costa Rica.

High-resolution vision in pelagic polychaetes

open access: yes
High-resolution object vision — the ability to separate, classify, and interact with specific objects in the environment against the visual background — has only been conclusively shown to have evolved in three of the thirty-five animal phyla: chordates,

Lesser Antillean Polychaetes, chiefly from brackish water with a Survey and a Bibliography of Fresh and Brackish – Water Polychaetes

open access: yes, 1958
The number of euryhaline polychaetes known at present is relatively small, when one considers that this almost exclusively marine order numbers hundreds of species. Only a few families have representatives in fresh water, viz.
