Extremely high but localized pulses of coral recruitment in the southwestern lagoon of New Caledonia and implications for conservation

Marine Ecology Progress Series, Journal Year: 2022, Volume and Issue: 692, P. 67 - 79

Recruitment processes largely drive spatial distributions, dynamics, and recovery potential of marine communities. Determining scales variation in recruitment rates composition can help understanding population replenishment mechanisms, while identifying hotspots is crucial for improving conservation strategies, particularly threatened ecosystems such as coral reefs. We examined the interannual variability (2012-2014) at multiple within among reef habitats (14 stations) southwestern lagoon New Caledonia. Recruit assemblages were characterized by high compared to other regions (overall mean 34.9 recruits per 11 × 1 cm settlement tile, corresponding 1220.9 m -2 ) strong dominance Acroporidae. found a marked heterogeneity but also exceptionally (100-fold), with extreme peaks (up 13572.8 , maximum 811 on single tile) recorded 2014 some fringing mid-shelf reefs, highest records ever reported date. These encouraging results contrast reefs where recent declines have been documented major concerns their resilience capacities. However, spatio-temporal complicates it makes difficult identify ‘recruitment hotspots’ priority sites protect capacity boost local populations.

Priorities for ecological research on cetaceans in the Galápagos Islands

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: Feb. 14, 2023

Located in the eastern tropical Pacific, Galápagos Islands are an oceanic insular ecosystem subject to strong environmental variability driven by local and regional processes. Past research has shown that such conditions can attract sustain at least 23 cetacean species, out of which 14 common, including nine Delphinids, one Ziphiid, Physeterid, three Balaenopterids. These species occupy both coastal habitats, most present year-round, a few migratory. However, on cetaceans been sporadic chronically underfunded is not currently considered priority agenda for Galápagos. Based review existing information assessment knowledge gaps, here we identify priorities ecological along five topical areas: 1) spatiotemporal occurrence, 2) population assessment, 3) health 4) social ecology, 5) trophic ecology. Addressing these gaps will also help inform actions preserve biodiversity manage human activities involving or affecting Given logistical funding challenges conducting Galápagos, recommend optimizing data sampling accessibility via integrated protocols open repositories. We capitalizing citizen science activities, as those conducted from cruise ships whale-watching tours, serve platforms opportunity obtaining basic data, thereby contributing long-term acquisition. Our proposed should be assessed Ecuadorian governmental institutions broad inclusive consultation with stakeholders scientific community prior development implementation agenda. Collectively, efforts advance our understanding role marine megafauna, cetaceans, play other islands, maintaining large-scale connectivity mitigating climate change.
