The orientation and position of hard substrata used to test ecological hypotheses about sessile marine plants and animals have often been based on logistical convenience. Much of our understanding of the ecology of epibiota is based on artificial habitats (particularly the undersides of floating pontoons), despite epibiotic organisms being an important and conspicuous component of natural hard ...

The paper deals with the standing stock of macrobenthic infauna and associated environmental factors influencing the benthic community in the shelf region of the northwest Indian coast. The data were collected onboard FORV Sagar Sampada during the winter monsoon (January-February, 2003) to understand the community structure and the factors influencing the benthic distribution. The environmental...

Polychaetes inhabiting deep-sea soft bottoms from the southeastern Gulf of California were collected during four oceanographic cruises during 2000 and 2001. Sampling of benthic organisms was performed with a benthic sledge to collect epifauna and a Karling dredge for epifauna and infauna, in a depth range from 732 to 2 250 m. A list of the polychaetes that were collected and their distribution ...

Multispecies, or mass, spawning of different invertebrate species is well known for coral reef systems; however, incidences involving polychaetes are poorly documented. In this study we report on mass swarming, prior to spawning, of Nereididae at Ambon Island, Maluku, on three occasions: in 1866, inferred from an historical sample deposited in Naturalis, Leiden, and in March, 2009 and 2014, bas...

The continuous increase of CO 2 emissions in the atmosphere due to anthropogenic activities is one most important factors that contribute Climate Change and generates phenomenon known as Ocean Acidification (OA). Research conducted at vents Castello Aragonese (Ischia, Italy), which represents a natural laboratory for study OA, demonstrated some organisms, such polychaetes, thrive under acidifie...

1. Evidence has been obtained showing that unlike the requirements of errant polychaetes studied by other investigators, at least two species of sedentary polychaetes, Branchiomma nigromaculata and Chaetopterus variopedatus can undergo caudal regeneration in the absence of a brain. 2. Both Branchiomma, when maintained in a brainless condition by repeated removal of anterior segments, and Chaeto...

Polychaetes have often been utilized as indicator species to investigate the impacts of pollutants, such as heavy metals. The uptake of Cd by the polychaete Nereis diversicolor was determined at varying Ca concentrations and with pre-exposure to Ca ion channel blockers and metabolic inhibitors in simulated sea water over 1 week period. The supply of Ca in simulated sea water inhibited Cd uptake...
