Characterization of anthropogenic marine macro-debris affecting coral habitat in the highly urbanized seascape of Mumbai megacity

Effects of seasonal variation on the characteristics of stranded marine debris within Rambut Island Wildlife Reserve, Indonesia

“…Upon analyzing the composition of plastic debris, it is then revealed that Styrofoam is the most prevalent type of debris, accounting for 63% at the mangrove station and 37% at the beach station (Table 2). The prevalence of the marine debris category in this study was similarly observed in the Lofoten Archipelago, Norway (Solbakken et al, 2022) and Mumbai, India (De et al, 2022). The significant number of plastic debris discovered cannot be disconnected from the tourist activities in the Seribu Islands zone.…”

Identifying Potential High-Risk Zones for Land-Derived Plastic Litter to Marine Megafauna and Key Habitats within the North Atlantic

“…Corals are unable to ingest large plastic litter, although microplastic ingestion is widespread (Allen et al, 2017;Hall et al, 2015;Reichert et al, 2018). Land-sourced plastic litter causing entanglement and smothering has been evidenced in many research papers (Abu-Hilal and Al-Najjar, 2009;Arindra Putra et al, 2021;De et al, 2022;Figueroa-Pico et al, 2016;Mueller et al, 2022;Mulochau et al, 2020;Richards and Beger, 2011;Santodomingo et al, 2021) as well as showing the negative impacts in laboratory studies (Mueller and Schupp, 2020). In the Gulf of Aqaba, the most common plastic items on the reef were single use items such as bags (61 %), bottles (24 %) and containers (13 %) (Abu-Hilal and Al-Najjar, 2009).…”

“…Large quantities of plastic litter have been found covering pneumatophores (specialised aerial root systems) and branches in mangrove systems (Cordeiro and Costa, 2010;Debrot et al, 2013;Fadare et al, 2022;Kesavan et al, 2021;Martin et al, 2019;Okuku et al, 2023;Paler et al, 2022;Sivasothi, 2002;Suyadi and Manullang, 2020), and is frequently found buried in mangrove sediments (Costa et al, 2011;van Bijsterveldt et al, 2021), where it causes the sediment to become anoxic (van Bijsterveldt et al, 2021). Single use plastics such as plastic bags and food wrappers are generally the most abundant type of plastic (De et al, 2022;Sivasothi, 2002).…”

“…Plastic covering roots or branches may lead to a physical impediment of gas exchange (Okuku et al, 2023), or prevent photosynthesis of the leaves (Kesavan et al, 2021), smothering the tree. Entanglement can cause physical damage to the pneumatophores and branches (De et al, 2022). Whilst mangroves are relatively resilient to partial smothering by plastic, large scale accumulation across the roots can lead to deterioration and tree death (van Bijsterveldt et al, 2021).…”

A temporal assessment of anthropogenic marine debris on sandy beaches from Ecuador’s southern coast

“…Therefore, the implications of the negative effects that AMD may have on bottom-living fauna is of great concern. Few studies have reported the potential negative impacts of entanglement of AMD on benthic organisms such as presence of longlines in coral colonies (Angiolillo et al, 2021), followed by signs of coral bleaching (De et al, 2022), and behavioral changes of benthonic fauna (Prestholdt and Kemp, 2020). Marine debris also causes direct economic impact in the fishing and aquaculture industry, shipping, and marine tourism.…”
