Localised admixture triggers parallel adaptation in a coral species trio on the Great Barrier Reef

Iva Popovic, Katharine E. Prata, Melissa Naugle, Ilha Byrne et autres

Abstract Hybridisation can shape evolutionary trajectories and fuel rapid adaptation. Yet, whether adaptive introgression repeatedly reconfigures genomes in predictable ways remains largely unknown. Here, we show that three-way admixture drives repeatable parallel differentiation in reef-building corals in the Acropora hyacinthus species complex. …

Long-distance gene flow and contrasting population structures of reef-building corals and their algal symbionts inform adaptive potential across the Western Pacific

Hugo Denis, Katharine E. Prata, H Ishida, Iva Popovic et autres

Abstract The genetic diversity and connectivity of reef-building coral populations are key to their survival in warming oceans. Yet our understanding of corals’ demographic resilience and adaptive potential is complicated by cryptic species diversity, wide geographic distributions, and complex coral-algal symbioses. To …

Multigenerational Tracking of Reef-Building Corals Using CRISPR-Cas9 induced Genetic Barcodes and eDNA Metabarcoding

Max Moonier, Line K. Bay, Yui Sato, Véronique J. L. Mocellin et autres

Abstract Widespread biodiversity loss driven by human activity has intensified global efforts to restore degraded ecosystems. Yet a key challenge remains: how to track restored individuals and their offspring over time and space to assess the true impact of restoration? This is …

Harnessing Multiscale Topographic Environmental Variables for Regional Coral Species Distribution Models

Annie S. Guillaume, Renata Ferrari, Oliver Selmoni, Véronique J. L. Mocellin et autres

ABSTRACT Effective biodiversity conservation requires knowledge of species' distributions across large areas, yet prevalence data for marine sessile species is scarce, with traditional variables often unavailable at appropriate temporal and spatial resolutions. As marine organism distributions generally depend on terrain heterogeneity, topographic …

Harnessing multiscale topographic environmental proxies in regional coral spatial modelling

Annie S. Guillaume, Renata Ferrari, Oliver Selmoni, Véronique J. L. Mocellin et autres

Effective biodiversity conservation requires knowledge of species’ distributions across large areas, yet prevalence data for marine sessile species is scarce. As marine organism distributions generally depend on terrain heterogeneity, topographic variables derived from digital elevation models (DEMs) can be useful proxies in …

Heat tolerance varies considerably within a reef-building coral species on the Great Barrier Reef

Melissa Naugle, Hugo Denis, Véronique J. L. Mocellin, Patrick W. Laffy et autres

Reef-building coral populations face unprecedented threats from climate warming. Standing variation in heat tolerance is crucial for evolutionary processes necessary for corals to persist. Yet, the spatial distribution of heat-tolerant corals and the underlying factors that determine heat tolerance are poorly understood …

Thermal tolerance traits of individual corals are widely distributed across the Great Barrier Reef

Hugo Denis, Line K. Bay, Véronique J. L. Mocellin, Melissa Naugle et autres

Adaptation of reef-building corals to global warming depends upon standing heritable variation in tolerance traits upon which selection can act. Yet limited knowledge exists on heat-tolerance variation among conspecific individuals separated by metres to hundreds of kilometres. Here, we performed standardized acute …

Environmental, host, and symbiont drivers of heat tolerance in a species complex of reef-building corals

Melissa Naugle, Hugo Denis, Véronique J. L. Mocellin, Patrick W. Laffy et autres

Abstract Reef-building coral populations are under unprecedented threat from climate warming. Yet, variation in coral heat tolerance exists whereby some colonies can cope with higher sea temperatures than others and thus may hold unique value for conservation and restoration. Here, we quantify …

Symbioses are restructured by repeated mass coral bleaching

Kate M. Quigley, Blake D. Ramsby, Patrick W. Laffy, Jessica Harris et autres

Survival of symbiotic reef-building corals under global warming requires rapid acclimation or adaptation. The impact of accumulated heat stress was compared across 1643 symbiont communities before and after the 2016 mass bleaching in three coral species and free-living in the environment across …

Genetic Variation in Heat Tolerance of the Coral Platygyra Daedalea Indicates Potential for Adaptation to Ocean Warming

Holland Elder, Virginia M. Weis, Jose Montalvo-Proaño, Véronique J. L. Mocellin et autres

Ocean warming represents the greatest threat to the persistence of reef ecosystems. Most coral populations are projected to experience temperatures above their current bleaching thresholds annually by 2050. Adaptation to higher temperatures is necessary if corals are to persist in a warming …
