“…This suggests that sh communities were comparatively stable after the bleaching disturbance. This stability despite high coral loss at some sites was probably in uenced by the presence of alternative and deeper habitats that provided shelter and/or food (Graham et al 2008;Quimpo et al 2018b;Dumalagan et al 2019;Albelda et al 2020). While offshore and wellmanaged reefs may experience lower localized stressors (Sandin et al 2008), they are still affected by large-scale global disturbances, including climate change and coral bleaching.…”

Climate change is perhaps the greatest threat to coral reefs worldwide. However, there is spatial variation in the extent and severity of this disturbance, with offshore and well-managed reefs presumed to minimize the consequences. In this study, sh and benthic communities at the offshore and wellmanaged reefs of Apo Reef Natural Park, Philippines was examined during (2016), 2 years (2018) and 3 years (2019) after bleaching disturbance. Fish and benthic surveys were conducted on scuba at 5 sites at depths of 8-10m. Results showed that benthic communities varied more strongly with year attributed to changes in the benthic cover of coral. These changes were also in uenced by site, with some sites experiencing coral loss of 41-48%, while at other sites there were minimal changes. These site differences were associated with the cover of coral pre-bleaching, with higher cover prior to the disturbance contributing to larger losses. Fish communities varied more with sites associated with differences in the predominant benthos among sites. The stability of sh communities with year despite coral loss may be attributed to the variable loss of coral cover among sites. For sites that experienced high losses of coral cover, the presence of alternative and/or deeper habitats may have provided shelter and food for shes maintaining taxonomic composition within sites. This study shows that bleaching disturbance circumvents localized protection, but impacts are variable even at small (≤ 3km) spatial scales. Community composition pre-bleaching and alternative habitats seem to buffer against the consequences of bleaching disturbance.

“…Malaysia comprises two major landmasses, Peninsular Malaysia and Sabah and Sarawak separated by 3 the Straits of Malacca, the Sulu Sea, and the southwestern part of South China Sea (Akhbar and Sohor, 2009;Mazlan et al, 2005). Exclusive Economic Zone of the east coast Peninsular Malaysia is located in the South China Sea, which is in the East Asian Ocean region that categorized as high diversity marine ecosystem with presence of Coral Triangle as the centre of tropical fauna and contains almost 76% of worldwide species (Albelda et al, 2020;Glasby et al, 2016;Hoeksema, 2007;Mazlan et al, 2005;Veron et al, 2009). On 25th April 1980, Malaysia had declared the Exclusive Economic Zone (EEZ) based on the 'new map Boundary Waters and continental shelf 1979' (RMN, 2007).…”

Aim: To examine the standing stock of macrobenthos along a depth gradient at regional scales in the Sunda Shelf of Malaysian Economic Exclusive Zone (EEZ). Methodology: Macrobenthos was sampled with a Smith–McIntyre grab at 19 stations on the continental shelf of the South-western South China Sea (east coast of Peninsular Malaysia) within the EEZ and was carried out onboard MV SEAFDEC II in May/June 2016. Results: The faunal composition, abundance, and diversity of species, together with environmental parameters were studied. A total of 10,232 individuals comprising 105 families were identified. The dominant macrobenthic group was Mollusca (55.25%), followed by Annelida (26.80%) and Arthropoda (15.36%), while the Echinodermata and Miscellaneous group recorded 1.13% and 1.43% respectively. Based on Bray-Curtis species similarities, five different sample groups (SGs) were distinguished, which were located in different zones and gradients of EEZ. Interpretation: Variations in the macrobenthic community is significantly associated with depth, temperature, and salinity. Further research should be conducted on other factors that contribute to the diversity of macrobenthos along the east coast of Peninsular Malaysia’s EEZ.

The decline of coral reefs has fueled interest in determining whether mesophotic reefs can shield against disturbances and help replenish deteriorated shallower reefs. In this study, we characterized spatial (horizontal and vertical) and seasonal patterns of diversity in coral recruits from Dabaisha and Guiwan reefs at Ludao, Taiwan. Concrete blocks supporting terra‐cotta tiles were placed at shallow (15m) and mesophotic (40m) depths, during 2016–2018. Half of the tiles were retrieved and replaced biannually over three 6‐month surveys (short‐term); the remainder retrieved at the end of the 18‐month (long‐term) survey. 451 recruits were located using fluorescent censusing and identified by DNA barcoding. Barcoding the mitochondrial cytochrome oxidase I (COI) gene resulted in 17 molecular operational taxonomic units (MOTUs). To obtain taxonomic resolution to the generic level, Pocillopora were phylotyped using the mitochondrial open reading frame (ORF), resolving eight MOTUs. Acropora, Isopora, and Montipora recruits were identified by the nuclear PaxC intron, yielding ten MOTUs. Overall, 35 MOTUs were generated and were comprised primarily of Pocillopora and, in fewer numbers, Acropora, Isopora, Pavona, Montipora, Stylophora, among others. 40% of MOTUs recruited solely within mesophotic reefs while 20% were shared by both depth zones. MOTUs recruiting across a broad depth distribution appear consistent with the hypothesis of mesophotic reefs acting as a refuge for shallow‐water coral reefs. In contrast, Acropora and Isopora MOTUs were structured across depth zones representing an exception to this hypothesis. This research provides an imperative assessment of coral recruitment in understudied mesophotic reefs and imparts insight into the refuge hypothesis.
