“…While changes in the communities of fishes and invertebrates were driven solely by a progressive increase in the number of species and their population size, which resulted in primary succession without species turnover (Mori et al, 2008), this was not the case for algae. In both the intertidal and subtidal communities of the lava flows, the transformations were more profound and involved shifts in specific composition (Supplementary Figure S1), aligning with typical seaweed succession on new substrates (Serisawa et al, 1998;Jung and Choi, 2022). Further, as observed in previous studies on lava flows (Doty, 1967;Jonsson, 1968;Zubia et al, 2018), initially, a community partially dominated by primary colonising species proliferated, but many of these taxa were gradually replaced by the dominant species in the climax communities.…”

We studied the primary succession of benthic communities in the lava flows of the Tajogaite volcano at 2, 4.5, and 7 months after the eruption ended. The lava from the Tajogaite created several lava flows and sterile rocky reefs that were monitored in both intertidal and subtidal areas up to 20 m depth. Sampling included macroinvertebrates and algae in the intertidal, and fishes, macroinvertebrates, and algae in the subtidal. A control zone was selected to compare the early colonisation of lava flows with that of a mature ecosystem. Colonisation of the lava flow was swift, with numerous species arriving and proliferating soon after the eruption ended. After 7 months, the total number of species recorded in the lava flows was 70, representing 64% of those found in the control zone. thus, communities were gradually becoming increasingly complex owing to the continuous incorporation of species. The number of fishes, and macroinvertebrates in both the intertidal and subtidal, lava flows increased progressively, approaching the values of the control zone. However, algae, in terms of total cover, presented values similar to the control zone from the beginning of the monitoring. All the communities have followed the same trajectory to converge towards communities like those in the control zone, although the rate at which they have changed with time differs. After seven months, differences in fishes between lava flows and the control zone were small, but they were still large with respect to macroinvertebrates and algae. Thus, according to each community of organisms, the benthic ecosystem of the lava flows was found at different stages of succession.

“…The increase or decrease of macroalgae species in an area normally occurs. Previous research stated that this was caused by the natural process of species succession in the community (Jung & Choi, 2022). This phenomenon happens immediately with the appearance of ephemeral species after the detachment of old algae (Tytlyanov et al, 2014).…”

Indonesia is a mega biodiversity country with abundant macroalgae. The macroalgae are distributed along the coast and function to maintain the balance of the coastal marine ecosystem, including in Bama Beach, Baluran National Park, Situbondo, Indonesia. This study was to determine the abundance, distribution, and diversity of macroalgae in Bama Beach Baluran National Park, East Java, between April 2019 and June 2019. The research was conducted with a purposive sampling method at two stations, each consisting of five substations using transect blocks. Five species of macroalgae from the Phaeophyceae class (Padina australis, Sargassum aquifolium, Polycladia myrica, Eucheuma edule, and Dictyota pinnatifida), a Rhodophyta (Jania pumila), and Chlorophyta (Halimeda macroloba) were found in the study site. Padina australis was a species that had the highest abundance and dominated the observation station. Nonetheless, according to the Shannon-Weaver Index in the study area, overall macroalgae diversity was classified as a low category with a value of 0.35. The high availability of nutrients influences these conditions in ecosystems with the domination of Padina australis, followed by Sargassum aquifolium at Station I and II.
