AbstractAlthough reef-building corals are rapidly declining worldwide, responses to bleaching vary both within and among species. Because these inter-individual differences are partly heritable, they should in principle be predictable from genomic data. Towards that goal, we generated a chromosome-scale genome assembly for the coral Acropora millepora. We then obtained whole genome sequences for 237 phenotyped samples collected at 12 reefs distributed along the Great Barrier Reef, among which we inferred very little population structure. Scanning the genome for evidence of local adaptation, we detected signatures of long-term balancing selection in the heat-shock co-chaperone sacsin. We further used 213 of the samples to conduct a genome-wide association study of visual bleaching score, incorporating the polygenic score derived from it into a predictive model for bleaching in the wild. These results set the stage for the use of genomics-based approaches in conservation strategies.

Abstract The responses of corals and other marine calcifying organisms to ocean acidification (OA) are variable and span from no effect to severe responses. Here we investigated the effect of long-term exposure to OA on skeletal parameters of four tropical zooxanthellate corals living at two CO2 vents in Papua New Guinea, namely in Dobu and Upa Upasina. The skeletal porosity of Galaxea fascicularis, Acropora millepora, and Pocillopora damicornis was higher (from 17% to 38%, depending on the species) at the seep site compared to the control only at Upa Upasina. Massive Porites showed no differences at any of the locations. Pocillopora damicornis also showed a ~ 7% decrease of micro-density and an increase of the volume fraction of the larger pores, a decrease of the intraskeletal organic matrix content with an increase of the intraskeletal water content, and no variation in the organic matrix related strain and crystallite size. The fact that the skeletal parameters varied only at one of the two seep sites suggests that other local environmental conditions interact with OA to modify the coral skeletal parameters. This might also contribute to explain the great deal of responses to OA reported for corals and other marine calcifying organisms.

Tujuan penelitian ini adalah mengetahui pertumbuhan, tingkat kelangsungan hidup dan mengetahui pengaruh frekuensi waktu pembersihan terhadap keberhasilan transplantasi karang keras (Acropora millepora) di Perairan Malang Rapat, Bintan. Penelitian ini dilakukan dengan metode transplantasi menggunakan modul terbuat dari semen berbentuk balok. Transplantasi karang dilakukan dengan empat perlakuan, perlakuan A (fragmen dibersihkan setiap 1 minggu), perlakuan B (fragmen dibersihkan setiap 2 minggu), perlakuan C (fragmen dibersihkan setiap 3 minggu) dan perlakuan D (tidak ada pembersihan fragmen) dengan 5 kali pengulangan setiap perlakuan. Pengamatan dilakukan setiap minggu selama 12 minggu penelitian. Hasil penelitian menunjukkan pertumbuhan mutlak pada perlakuan A sebesar 14,94 ± 4,98 mm, perlakuan B sebesar 18,16 ± 5,93 mm, perlakuan C sebesar 12,30 ± 3,78 mm dan perlakuan D sebesar 12,22 ± 4,34 mm. Laju pertumbuhan fragmen karang pada perlakuan A sebesar 1,24 ± 0,41 mm/minggu, perlakuan B sebesar 1,51 ± 0,49 mm/minggu, perlakuan C sebesar 1,02 ± 0,31 mm/minggu, dan laju perlakuan D sebesar 1,01 ± 0,36 mm/minggu. Tingkat kelangsungan hidup fragmen karang Acropora millepora pada perlakuan A dan B sebesar 100% (tidak mengalami kematian), sedangkan perlakuan C dan D sebesar 83,08% (mengalami kematian). Hasil uji statistik menunjukkan terdapat perbedaan yang nyata antara pertumbuhan karang Acropora millepora berdasarkan perbedaan waktu pembersihan. Perlakuan B (pembersihan fragmen setiap 2 minggu sekali) merupakan perlakuan dengan pertumbuhan optimum.
