Abstract:
The Sawu Sea National Marine Park is a marine conservation area in East Nusa Tenggara Province that is known for its high marine biodiversity. The coral reef ecosystem in this conservation area is home to ecologically and economically important megabenthic organisms. Megabenthos are important regulators of marine ecosystems, acting as indicators of coral reef health. However, information on the types and densities of megabenthos in this conservation area is scarce. Research on megabenthos is critical for assessing coral reef health and informing conservation strategies. The aim of this study i

Abstract:
This long-term observation of the faunal composition within the Barents Sea provides a benchmark for monitoring community changes caused by oceanographic variability, fishery activities, and crab predators (Chionoecetes opilio, Paralithodes camtschaticus), whose populations have been rapidly growing and spreading in recent years. In the Arctic systems, megabenthic communities comprise a significant part of benthic biomass and play an important role in carbon cycling on continental shelves. The gradual accumulation of knowledge on megabenthos may make it possible to assess their role in the eco

As a part of a marine expedition on the R/V «Dalnye Zelentsy» along the western coast of the Novaya Zemlya archipelago, an assessment of megabenthic species diversity and biomass in bycatch of trawl was carried out in August 2023 specimens of 29 taxa belonging to 6 phyla were identified during the survey. The highest species diversity (20 species) was recorded in the northern coastal area of the Novaya Zemlya archipelago, where the dominant forms in terms of biomass were sea urchins Strongylocentrotus pallidus – 237.1 kg/km2.

Abstract:
Mediterranean bottom trawling is generally characterised by a highly diversified mixed catch, composed of fish, cephalopods,crustaceans, and other megabenthic invertebrates. Although management of Mediterranean trawling requires a multispecies approach on a community basis, this does not seem to be the case in the relevant literature. Herein, we present an extensive review ofthe existing knowledge on megabenthic invertebrate communities, focusing on the trawlable bottoms. A total of 207 publicationsfrom 1930 to the early 2021 was collected and classified into seven research areas. Research eff

The aim of this paper is to bring to light the knowledge of marine diversity of invertebrates in Gabes gulf. The spatial distribution of the megabenthic fauna community in Gabes gulf (Tunisia, Eastern Mediterranean Sea), together with the bottom type and vegetation cover, were studied. The abundance of the megabenthic fauna was represented by eight groups: Echinodermata (38%), Crustacea (21%), Tunicata (19%), Mollusca (13%), Porifera (4%), Cnidaria (3%), Bryozoa, and Annelida (2%). It was spatially more concentrated in the coast area of the gulf than in the offshore waters. This area, especial

Abstract:
The coral reef was a habitat for several groups of biota that live in this ecosystem. Some species or group species of benthic fauna are known to be ecologically important and others are economically important so that they can be used as indicators to assess reef health. Research on megabenthic fauna in Ternate and its surrounding waters, North Maluku, was carried out in 2012, 2015, 2016, 2017 and 2018 at fourteen permanent stations. The purpose of this study was to determine the fluctuations in several megabenthic faunae temporarily. Data were collected using the modified Belt Transect Method

Abstract:
The introduction of a large predatory snow crab, Chionoecetes opilio, into the Kara Sea is a unique situation where the impact of an invasive species affecting an otherwise undisturbed ecosystem can be observed unhindered by other ecosystem stressors. Trophic interactions are one of the principal relationships between animals and can help assess an ecosystem’s stability. The trophic positions and sources of organic material for the most common benthic species of Blagopoluchiya Bay sampled at different stages of the invasion were calculated using stable isotope analysis.

Abstract:
Seagrass ecosystems play a crucial role in coastal environments, providing essential habitats for the survival of various marine species. One significant group associated with these ecosystems is benthic organisms, which inhabit the ocean floor. This study aims to evaluate the relative abundance of megabenthic organisms in the seagrass ecosystem surrounding Mantang Island. Sampling was conducted at three stations. The results showed that seagrass cover in the waters of Mantang Island ranged from 25.5% to 40.31%, indicating a moderate level of seagrass coverage. Four main groups of megabenthic

Abstract:
Abstract The development of ecosystem-based fisheries management over the last two decades has increased attention on the protection of vulnerable resources that are of little or no economic significance including bycatch of benthos in bottom trawling. Current knowledge on the response of benthic communities to the impact of trawling is still rudimentary. In the present study, we used data collected in the Barents Sea during 2011 to assess the vulnerability of benthic species to trawling, based on the risk of being caught or damaged by a bottom trawl. Using trait table analysis, we identified

A previously undocumented shallow water hydrothermal field from Sicily (Southern Tyrrhenian Sea, Italy) is here described, based on a multidisciplinary investigation. The field, covering an area of nearly 8000 m2 and a depth from the surface to -5 m, was explored in June 2021 to characterise the main physico-chemical features of the water column, describe the bottom topography and features, and identify the main megabenthic and nektonic species. Twenty sites were investigated to characterise the carbonate system. Values of pH ranged between 7.84 and 8.04, ΩCa between 3.68 and 5.24 and ΩAr from

The disturbance axis of the template is modeled based on the information on sediment, currents, and bathymetry. The adversity axis is modeled based on
