Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats
Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Asteroids, ophiuroids and holothurians from the southeastern Weddell Sea (Southern Ocean)
ZooKeys, 2014 Until the early 1980s, the composition and distribution of the asteroid (starfish), ophiuroid (brittle star) and holothurian (sea cucumber) bottom fauna of the southeastern Weddell Sea was virtually unknown.

Journal of Biogeography, Volume 53, Issue 6, June 2026.ABSTRACT Aim The biogeography and evolution of South African sea cucumbers have been previously explored; however, these aspects lack detailed study. This study (1) explores the biogeography of sea cucumbers along the coastline of South Africa (SA) and (2) presents a preliminary molecular phylogeny based on the mitochondrial 16S marker.

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Adaptational Significance of the Patterns of Ophiuroid Development [PDF]
American Zoologist, 1975 There is only limited information on ophiuroid developmental patterns, larvae being known for only 4% of the 2000 living ophiuroids. Three modes of development are distinguished (planktotrophic, direct, abbreviated) on the basis of egg size and number, larval form and life span, and post-larval size. This generalization is applied to an analysis of the

Dehydroophioxanthin, a new acetylenic carotenoid sulfate from the ophiuroid Ophiocomina nigra
, 1991 A new carotenoid, designated as dehydroophioxanthin (I), has been isolated from the ophiuroid O. nigra. The structure was detd.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions
