“…Straddling the interface between marine and terrestrial ecosystems, they provide important buffers that dissipate wave energy, stabilising coastlines and protecting against coastal erosion and natural hazards such as hurricanes and tsunamis (Williams 2005 ; Wee et al 2019 ). Mangroves provide critical ecological habitats that host high levels of biodiversity and act as a nursery for many juvenile coral reef species (Abu El-Regal and Ibrahim 2014 ; Mehvar et al 2018 ). Despite these benefits, mangrove clearance for aquaculture and urban development is rampant in many areas of the world.…”

Distinct fungal communities associated with different organs of the mangrove Sonneratia alba in the Malay Peninsula

Mangrove forests are key tropical marine ecosystems that are rich in fungi, but our understanding of fungal communities associated with mangrove trees and their various organs remains limited because much of the diversity lies within the microbiome. In this study, we investigated the fungal communities associated with the mangrove tree Sonneratia alba throughout Peninsular Malaysia and Singapore. At each sampling location, we collected leaves, fruits, pneumatophores and sediment samples and performed amplicon sequencing of the ribosomal internal transcribed spacer 1 to characterise the associated communities. Results show distinct fungal communities at each sampled location with further differentiation according to the plant part. We find a significant distance decay of similarity, particularly for sediment samples due to the greater variability of sediment environments relative to the more stable fungal habitats provided by living plant organs. We are able to assign taxonomy to the majority of sequences from leaves and fruits, but a much larger portion of the sequences recovered from pneumatophores and sediment samples could not be identified. This pattern underscores the limited mycological research performed in marine environments and demonstrates the need for a concerted research effort on multiple species to fully characterise the coastal microbiome and its role in the functioning of marine ecosystems.

“…Shallow tropical and subtropical coastal habitats such as lagoons, mangroves, estuaries, and coral reefs serve as important habitats for coastal fishes, providing shelter and serving as nursery grounds during their early life stages (Blaber, Brewer & Salini, 1995; Paterson & Whitfield, 2000; Franco et al, 2006; Abu El‐Regal & Ibrahim, 2014). Shallow intertidal zones and sea reefs (bioherms) can also function in a similar capacity (Nagelkerken et al, 2000; Hajisamae & Chou, 2003), and given their importance as breeding grounds and sources of recruitment, are crucial for maintaining the stability of marine ecosystems (Nagelkerken et al, 2000; Courrat et al, 2009).…”

Coastal development threatens Datan area supporting greatest fish diversity at Taoyuan Algal Reef, northwestern Taiwan

Taoyuan Algal Reef is a biodiverse coralline algal reef in north‐west Taiwan, that is currently threatened by coastal development and industrial waste runoff. As the reef lies in an exposed area that is frequently disturbed by monsoons, it is difficult to survey using traditional methods. Knowledge of the reef is therefore limited, and has until recently, long been regarded as a barren environment. However, recent studies have revealed that the reef is inhabited by a diverse array of organisms, particularly at Datan, where a natural gas receiving terminal is planned for construction. Due to challenging environmental conditions, otolith assemblage and soundscape analyses were used to supplement traditional sampling methods including clove oil, netting, and pole‐and‐line fishing in order to assess the diversity of the fish community at Taoyuan Algal Reef. Several fish species that had not been recorded by previous surveys were observed. Fish diversity and the average size of commercially targeted species were greatest at Datan G2. Predatory reef fishes such as groupers (Serranidae) and snappers (Lutjanidae), as well as several small endangered scalloped hammerhead sharks Sphyrna lewini were recorded at G2, where otolith assemblage analysis also indicated increased predatory activity. However, fewer individuals and species were recorded from tidal pools across all sites compared to previous surveys, suggesting a loss of biodiversity. If construction work resumes at Datan, it will be likely to have adverse consequences for the reef itself, the species that inhabit it, and by extension, the local fishermen that rely upon it. Halting additional coastal development, reducing industrial and domestic pollution, as well as improving the management of traditional fisheries is recommended to protect this unique reef ecosystem from further degradation.

“…A major reason behind mangrove deforestation is the inability to value the ecological functions and services provided by this system (Saenger et al 1983, Barbier 2006, Carugati et al 2018. Mangrove habitats are generally accepted as fish nurseries (Robertson and Duke 1987, Laegdsgaard and Johnson 1995, Manson et al 2005a, El-Regal and Ibrahim 2014, providing refuge for fish from predators (Igulu et al 2013), and fishery landings are higher in areas adjacent to mangrove forests (Manson et al 2005b, Meynecke et al 2007). Mangrove habitats are generally accepted as fish nurseries (Robertson and Duke 1987, Laegdsgaard and Johnson 1995, Manson et al 2005a, El-Regal and Ibrahim 2014, providing refuge for fish from predators (Igulu et al 2013), and fishery landings are higher in areas adjacent to mangrove forests (Manson et al 2005b, Meynecke et al 2007).…”

“…Situated in the intertidal zone, mangrove forests are critical in supporting world fisheries production (Manson et al 2005a,b, Nagelkerken and Faunce 2008, Pantallano et al 2018. Mangrove habitats are generally accepted as fish nurseries (Robertson and Duke 1987, Laegdsgaard and Johnson 1995, Manson et al 2005a, El-Regal and Ibrahim 2014, providing refuge for fish from predators (Igulu et al 2013), and fishery landings are higher in areas adjacent to mangrove forests (Manson et al 2005b, Meynecke et al 2007). Nevertheless, the detailed mechanisms on how vegetation structure affects fish community have yet to be resolved (Abrantes et al 2015), and there is a pressing need to increase our knowledge of the fish associated with mangrove ecosystems (R€ onnb€ ack et al 1999).…”

Distribution of fish among Avicennia and Sonneratia microhabitats in a tropical mangrove ecosystem in South China

Mangrove structural complexity plays an important role in the way fish using their habitat.However, the effects of structural attributes on fish spatial distribution remain uncertain. In this study, we sampled fish at three easily identifiable microhabitats (i.e., vegetated area with both mangrove trees and pneumatophores, pneumatophore area without trees, and adjacent mudflat without trees and pneumatophores) within two sites dominated by Avicennia marina and Sonneratia apetala in a large estuarine system in South China from 2014 to 2015, and explored the fish community differences in these microhabitats. Our results showed that fish assemblages varied significantly among the three microhabitats, with distinct community assembly patterns between sites. At the Avicennia site, highest fish diversity was recorded at the mudflat, followed by the pneumatophore area and the vegetated area. In contrast, the opposite pattern was observed at the Sonneratia site. Fish size also differed significantly among microhabitats, with smaller fish presented in the vegetated areas. Within the same mangrove types, the height and biomass of pneumatophores as well as density of trees showed significant effects on the among-microhabitat variations of fish assemblages. Fish abundance was positively associated with pneumatophore height and negatively correlated with pneumatophore biomass at the Avicennia site. While at the Sonneratia site, it was positively correlated with pneumatophore biomass. We conclude that the spatial variations of fish community are highly correlated with the structural complexity of mangroves. However, the specific effects might be mangrove species-dependent.
