Marine heatwaves are becoming more frequent, widespread and severe, causing mass coral bleaching mortality. Natural adaptation may be insufficient to keep pace with climate warming, leading calls for selective breeding interventions enhance the ability of corals survive such heatwaves, i.e., their heat tolerance. However, heritability this trait-a prerequisite approaches-remains unknown. We show that selecting parent colonies high rather than low tolerance increased adult offspring...
Marine heatwaves and mass bleaching have devastated coral populations globally, yet severity often varies among reefs. To what extent a reef’s past exposure to heat stress influences mortality remains uncertain. Here we identify persistent local-scale hotspots thermal refugia the reefs of Palau, Micronesia, based on 36 years satellite-derived cumulative (degree heating weeks–DHW, units: °C-weeks). One possibility is that may harbour more tolerant corals due acclimatisation, directional...
For sessile broadcast spawning marine invertebrates, such as corals, successful sexual reproduction depends on conspecifics synchronously. The precise monthly, lunar, and diel timing the extent of synchrony, i.e., proportion population reproducing at same time, are likely to play a key role in coral recovery, persistence, adaptation. Despite its importance, mechanisms by which different environmental factors trigger corals spawn specific dates within lunar cycle remain poorly understood....
Abstract Mating changes female behaviour and physiology across a wide range of taxa, with important effects for male fitness. These are often induced by components the ejaculate, such as sperm seminal fluid proteins. However, males can vary significantly in their ejaculates, due to factors age, mating history or nutritional status. This variation may therefore lead strength responses stimulate females, alterations fitness outcomes both sexes. Using fruit fly, Drosophila melanogaster , we...
<title>Abstract</title> Marine heatwaves are becoming more frequent, widespread and severe1, leading to mass coral bleaching mortality. Yet it remains unknown whether natural adaptation can keep pace with climate warming2. As a result, selective breeding has been proposed enhance heat tolerance3. The viability of this management solution hinges on the extent heritability tolerance. We show that selecting parent colonies for tolerance results in higher adult offspring. This result held true...
Abstract Marine heatwaves and mass bleaching have led to global declines in coral reefs. Corals can adapt, yet, what extent local variations thermal stress regimes influence heat tolerance adaptive potential remains uncertain. Here we identify persistent local-scale refugia hotspots among the reefs of a remote Pacific archipelago, based on 36 years satellite-sensed temperatures. Theory suggests that should promote through acclimatisation directional selection. While historic patterns marine...
