Increases in the magnitude, frequency, and duration of warm seawater temperatures are causing mass coral mortality events across globe. Although, even during most extensive bleaching events, some reefs escape exposure to severe stress, constituting potential refugia. Here, we identify present-day climate refugia on Great Barrier Reef (GBR) project their persistence into future. To do this, apply semi-dynamic downscaling an ensemble projections released for IPCC's recent sixth Assessment Report. We find that GBR locations experiencing least thermal stress over past 20 years have done so because oceanographic circumstance, which implies longer-term is feasible. Specifically, tidal wind mixing water away from sea surface appears provide relief warming. However, average this relative advantage only persists until global warming exceeds ~3°C.

Abstract Water temperature is a strong driver of growth, survival, and local adaptation in corals, but our knowledge the temperatures experienced by corals on reefs worldwide remains limited. While situ loggers can provide high quality data, they are relatively expensive to place retrieve. Alternatively, remotely sensed sea surface data globally available may be biased representation corals. Here, we compared from 314 coral ~ 1 km 2 resolution Multi-scale Ultra-high Resolution Sea Surface Temperature (MUR) product NASA. We found good agreement (Pearson’s r = 0.95) between maximum monthly mean calculated remote with 84% within 0.5 °C each other. However, did not effectively capture sub-diel fluctuations highest peak that most dangerous for Predictions were significantly weakly improved consideration reef geomorphology. Ultimately, accurately represent conditions should used caution at finer temporal scales.

Abstract Satellite sea surface temperature (SST) is critical for describing marine environments. Traditional SST data, such as those provided by the Group High Resolution Sea Surface Temperature (GHRSST) program, are valuable, but have a relatively coarse spatial resolution mapping coral reef thermal Hence, fine from orbit would be of great utility to research community and speed pathway an increased understanding how, when, where stress afflicts individual reefs. Such data support adaptive management, especially so design protected areas. Flying aboard International Space Station, NASA ECOsystem Spaceborne Thermal Radiometer Experiment on Station (ECOSTRESS) instrument may already fill this niche with 204 times finer than GHRSST. To evaluate ECOSTRESS over environments, we deployed 21 loggers three years across two sites in Red Sea. We compared retrievals both GHRSST resolution, experimental, ECOSTRESS, in-situ logger dataset. While orbital platforms correlated strongly recordings, only its 70-m pixels, could construct microclimate maps capturing dynamic fluctuations experienced our studied contend that represents significant advancement capability monitor heat reefs orbit.

Coral sexual recruitment is critical to reef recovery yet often fails on degraded reefs. seeding one approach artificially increase the densities of coral settlers reefs and can be applied in many ways. A thorough comparison seeding‐method performance needed inform restoration decisions difficult undertake given cost complexities around employing multiple methods simultaneously. Here, we first designed a vessel‐based coral‐spawning aquaculture system. Then undertook an experimental larvae reared on‐vessel system with those situ rearing pools (SECORE basins [CRIBs]). We parameterized survival estimates assessed post‐deployment spat generated using each method. also quantified deployed across six sites inshore Great Barrier Reef. Larval was lower when than vessel (3.8 vs. 66.1%, respectively), but settlement behavior post‐settlement were comparable between treatments, yield averaging 66 72% after 3 months deployment, from CRIBs culture tanks, respectively. Spat 5 ± 8%. On‐vessel more costly supported higher survival, increased portability, enabled control manipulation conditions. By contrast, low‐cost, deployable shore, low‐maintenance. Armed this information, managers practitioners determine most appropriate method(s) for project.

The symposium "Evolutionary Applications" took place on June 28, 2024 in the virtual part of 3rd Joint Congress Evolutionary Biology. It was contributed to conference by European Society for Biology (ESEB). highlighted research evolutionary biology applied address questions and contemporary problems medicine public health, conservation biology, food production agriculture. Each six talks covered a different application organism: domestication cheese-making fungi, restoration long-lived bird populations, evolution herbicide resistance, coral reef conservation, gene drive systems targeting Malaria vectors, antibiotic resistance bacteria. By including speakers who are active consortium or work an NGO, also showed how make step from scientific findings practical application. furthermore featured range methods, ranging genomic analyses mathematical modeling laboratory field experiments. Speakers across 15 time zones potential symposia foster global collaboration biology.
