Article Abstract

Seasonal survey was performed from August 2015 to May 2016 at 50 sampling sites in Lake Taihu to determine the spatial and temporal changes in macrobenthos community and their relationships with environmental variables. A total of 58 macrobenthos species were collected and identified, including 28 species of annelids, 17 species of molluscs, and 12 species of arthropods. Both the community composition and the dominant species changed temporally and spatially. Correspondingly, the macrobenthos biodiversity differed among regions and seasons. The macrobenthos density decreased with increased sediment depth, which is the first report about the vertical distribution of macrobenthos in Lake Taihu. The majority of benthic animals were located within the sediment depth of 0-5 cm and 5-10 cm, accounting for 39.25% and 24.87% of the total abundance respectively. Redundancy discriminate analysis revealed that the main environmental factors affecting the most contributing macrobenthos species were temperature in summer, transparency, dissolved oxygen and pH in autumn, and water depth and dissolved oxygen in winter. Particularly, salinity and conductivity showed high correlation with the macrobenthos community through the whole sampling period. The investigation reveals the inherent spatiotemporal variation of macrobenthos community, and provides references for the biological assessment of water quality in Lake Taihu.

The distribution characteristics of marine litter in the intertidal zone of Lvhua Island and its impact on the macrobenthic community structure.

Marine litter typically originates from human discards at sea or enters the ocean through land-based pathways such as surface runoff and natural disasters. The extensive accumulation of plastic litter poses severe threats to marine life. In August 2024, a specialized survey was conducted to investigate the distribution characteristics of marine litter and macrobenthic communities across four intertidal zones on Lvhua Island (XIAO'AO, DA'AO, FANGANG, and SHIZIKENG).

Coastal sediments in semi-enclosed bays are particularly susceptible to contamination due to limited water circulation and ongoing contaminant input. In Masan Bay, a heavily impacted coastal area in Korea, sediment remediation is essential to alleviate the effects of organic enrichment and hypoxia. This study investigated the effectiveness of oyster shell capping as an in-situ remediation technique by assessing its impact on sediment environment, microbial communities, and macrobenthic fauna.

Mangrove ecosystems in Bedono Village, Demak Regency, Central Java, are seriously degraded due to aggressive coastal abrasion, extreme soil salinity (45‰-80‰), and failure of previous rehabilitation programmes. This study aims to assess the level of vulnerability of mangrove habitat and formulate an integrated rehabilitation strategy that includes ecological and institutional aspects. Data were collected through tidal analysis, measurement of sediment texture and soil salinity, identification of plankton and macrobenthos diversity, and analysis of mangrove species community structure.

Biodiversity monitoring in bamboo coral assemblages in the North Aegean Sea, eastern Mediterranean Basin.

Deep-sea bamboo coral assemblages are often undescribed in the eastern Mediterranean Sea. Their structural complexity provides essential habitats for many species and promotes high biodiversity that is poorly known. In this study, we examined the effects of coral presence on biodiversity of benthic communities from a scientific trawl survey in the North Aegean Sea carried out in 2018.

Many oil and gas platforms in the North Sea are nearing their end of life and there is an urgent need to understand the legacy effects of associated seabed contamination on benthic communities. We use data from industry-based monitoring surveys, 1985-2015, in a North Sea wide study to investigate change in contaminants and the biomass of benthic functional groups (small infauna, small mobile epifauna, infaunal macrobenthos, and epifaunal macrobenthos). Total hydrocarbon concentrations in sediment samples exceeded 150,000 μg/g between 1992 and 1998 and within 250 m of 6 different platforms.
