Constraints on organisms possessing a unitary body plan appear almost absent from colonial organisms. Like organisms, however, coral colonies seemingly delay reproduction until reaching critical size. Elucidating ontogenetic processes, such as puberty and aging are complicated by corals' modular design, where partial mortality fragmentation lead to distortions in colony size-age relationships. We explored these enigmatic relations their influence fragmenting sexually mature of five species into sizes below the known size at first reproduction, nurturing them for prolonged periods, examining reproductive capacity trade-offs between growth rates investment. Most fragments were regardless size, hardly affected reproduction. Our findings suggest that once milestone is reached, corals retain irrespective highlighting key role may have animals, which commonly considered non-aging.

Abstract Trait-based approaches advance ecological and evolutionary research because traits provide a strong link to an organism’s function fitness. might lead deeper understanding of the functions of, services provided by, ecosystems, thereby improving management, which is vital in current era rapid environmental change. Coral reef scientists have long collected trait data for corals; however, these are difficult access often under-utilized addressing large-scale questions. We present Trait Database initiative that aims bring together physiological, morphological, ecological, phylogenetic biogeographic information into single repository. The database houses species- individual-level from published field experimental studies alongside contextual important framing analyses. In this descriptor, we release 56 1547 species, collaborative platform on other being actively federated. Our overall goal become open-source, community-led clearinghouse accelerates coral research.

Abstract Sea-surface temperature (SST) warming events, which are projected to increase in frequency and intensity with climate change, represent major threats coral reefs. How these events impact reef carbonate budgets, thus the capacity of reefs sustain vertical growth under rising sea levels, remains poorly quantified. Here we quantify magnitude changes that followed ENSO-induced SST affected Indian Ocean region mid-2016. Resultant bleaching caused an average 75% reduction cover (present mean 6.2%). Most critically report declines shallow fore-reef shifting from strongly net positive (mean 5.92 G, where G = kg CaCO 3 m −2 yr −1 ) negative −2.96 G). These have driven reductions potential, declined 4.2 −0.4 mm . Thus habitats now a phase erosion. Based on past recovery trajectories, predicted increases frequency, predict prolonged period suppressed budget states. This will limit track IPCC projections sea-level rise, limiting natural breakwater threatening island stability.

Although there considerable among-species variability responses increasing temperature seawater chemistry, changing regimes likely have influence fish assemblages, at least over short–medium timeframes. Recent evidence bleaching thresholds, local genetic adaptation inheritance heat tolerance suggest that populations may some capacity respond warming, although extent which these changes can keep pace with environmental conditions unknown.
