Data from: Fishes alleviate the impacts of sediments on host corals

Tory J. Chase, Morgan S. Pratchett, Michael J. McWilliam, Margaux Y. Hein, Sterling B. Tebbett & Mia O. Hoogenboom
Mutualisms play a critical role in ecological communities, however the importance and prevalence of mutualistic associations can be modified by external stressors. On coral reefs, elevated sediments are a major stressor, reducing the health of corals and damaging reef resilience. Here, we investigated the influence of sediment stress on the mutualistic relationship between small damselfishes (Dascyllus aruanus and Pomacentrus moluccensis) and their coral host (Pocillopora damicornis). In an aquaria experiment, corals were exposed to sedimentation...

Data from: Natal philopatry increases relatedness within groups of coral reef cardinalfish

Theresa Rueger, Hugo Harrison, Peter Buston, Naomi Gardiner, Michael Berumen & Geoffrey Jones
A central issue in evolutionary ecology is how patterns of dispersal influence patterns of relatedness in populations. In terrestrial organisms, limited dispersal of offspring leads to groups of related individuals. In contrast, for most marine organisms, larval dispersal in open waters is thought to minimise kin associations within populations. However, recent molecular evidence and theoretical approaches have shown that limited dispersal, sibling cohesion, and/or differential reproductive success can lead to kin-association and elevated relatedness. Here,...

Limited evidence of cloning and selfing within wild populations of coral-eating crown-of thorns seastar (Acanthaster cf. solaris)

Sven Uthicke, Morgan Pratchett, Vanessa Messmer & Hugo Harrison
Population outbreaks of crown-of-thorns seastars (CoTS; Acanthaster spp.) are contributing to extensive coral loss and reef degradation throughout the Indo west-Pacific, but the causes and underlying mechanisms of population maintenance and outbreaks are equivocal. Two recent publications suggest that, in addition to outbreeding sexual reproduction, asexual reproduction through larval fission and selfing may contribute to rapid increases in the local abundance of Acanthaster spp. We re-analysed two large microsatellite datasets (collectively representing 3,714 individuals) that...

Critical thermal maxima of early life stages of three tropical fishes: effects of rearing temperature and experimental heating rate

Björn Illing, Adam T. Downie, Mahaut Beghin & Jodie L. Rummer
Marine ectotherms are often sensitive to thermal stress, and certain life stages can be particularly vulnerable (e.g., larvae or spawners). In this study, we investigated the critical thermal maxima (CTmax) of larval and early juvenile life stages of three tropical marine fishes (Acanthochromis polyacanthus, Amphiprion melanopus, and Lates calcarifer). We tested for potential effects of developmental acclimation, life stage, and experimental heating rates, and we measured metabolic enzyme activities from aerobic (citrate synthase, CS) and...
