“…Such cases have been reported in the coral population of Seriatopora hystrix in the Flinders Reef (Noreen et al 2009) and Porites lutea in the South China Sea (Huang et al 2018). Both populations of E. lamellosa show higher genetic diversity values than other coral populations from Sulawesi waters and the eastern Lesser Sunda Islands (Jompa et al 2020;Rosser et al 2020). Several studies suggest that recolonization from longdistance source reefs contributes to relatively greater genetic diversity value in a recently established coral population (Starger et al 2010;Aurelle et al 2020;Smallhorn-West et al 2020).…”

Genetic diversity has an important role in the stability of coral populations in coping with disturbances. In the last three bleaching events, the coral Echinopora lamellosa survived better in the eastern- than the western- Lombok waters that are not related to algal symbiont diversity. The present study aimed to assess the genetic diversity of E. lamellosa from the two locations in the Lombok waters. The ITS1-5.8S-ITS2 (whole ITS region) marker was used to identify and to determine the genetic structure, genetic variation, and demographic pattern of E. lamellosa. The results showed that E. lamellosa of the two locations are two different populations. The haplotype diversity was very high indicating a predominance of sexual reproduction mode for both eastern and western populations. The phylogenetic topology suggests there is possible connectivity between populations, whereas the haplotype network exhibits a restricted gene flow between the two populations. The results suggest that the present E. lamellosa populations were from both surviving colonies and new recruitment of long-distance larvae. Both population likely shares the same larvae supply brought from source-reefs in the Flores Sea or Makassar Strait by the Indonesian Throughflow. The present and previous studies revealed that genetic diversity alone yet to explain the resistance of E. lamellosa in eastern and western Lombok waters.

“…However, there is a need for updated and/or complementary data on certain aspects of coral community biodiversity, ecology and health. Molecular biology methods are gaining in popularity for a wide range of biodiversity-related studies in the marine realm (Bourlat et al 2013;Bowen et al 2014;von der Heyden et al 2014;Crandall et al 2019) including for corals (Gittenberger et al 2011;Umar et al 2019;Jompa et al 2020). In particular, environmental DNA (eDNA) can provide data on the taxonomic groups present (Berry et al 2019), and in some cases also provide an indication of relative abundance (Kutti et al 2020).…”

Abstract. Yusuf S, Beger M, Tassakka ACMAR, Brauwer MD, Pricella A, Rahmi, Umar W, Limmon GV, Moore AM, Jompa J. 2021. Cross shelf gradients of scleractinian corals in the Spermonde Islands, South Sulawesi, Indonesia. Biodiversitas 22: 1415-1423. Coral reef ecosystems around the world have suffered extensive degradation, including the reefs of the Wallacea region within the Coral Triangle global biodiversity hotspot. Anthropogenic and natural threats can reduce the level of coral reef biodiversity differentially across environmental or impact gradients. The purpose of this study was to evaluate the changes in hard coral (Scleractinia) diversity and community structure across an inshore-offshore zonation gradient in the Spermonde Islands, South Sulawesi, Indonesia. Data on coral colony species and abundance as well as live coral cover were collected from 10 m2 belt transects at a depth of 6 to 8 m. A total of 72 transects were placed around the 12 island stations in three zones: the inner mid-shelf zone, outer mid-shelf zone and outer shelf zone. Data were analyzed to determine the species richness, and three ecological indices for the hard coral communities were calculated: the Shannon Diversity Index (H'), Similarity Index (E), and Dominance Index (C). A total of 310 hard coral species belonging to 62 genera were recorded. The coral communities were dominated by the genera Fungia, Montipora and Porites, and coral cover was in the 'moderate' category. The number of species was directly proportional to the number of colonies within each zone. Live coral cover was higher in the inner mid-shelf zone and outer shelf zone than the outer mid-shelf zone; conversely, the species richness and coral colony abundance were higher in the outer mid-shelf zone. However, the differences were not statistically significant. The indices H’, C, and E did not differ significantly between the zones. However, Tambakulu Island in Zone 4 had the lowest values of E and H’ and the highest value of C. Findings suggest that most-hard coral communities in the cross-shelf zones of the Spermonde Islands are stable communities characterized by relatively high diversity and low dominance indices.
