Data from: Low recruitment due to altered settlement substrata as primary constraint for coral communities under ocean acidificationKatharina E. Fabricius, Sam H.C. Noonan, David Abrego, Lindsay Harrington, Glenn De'ath & Sam H. C. Noonan
The future of coral reefs under increasing CO2 depends on their capacity to recover from disturbances. To predict the recovery potential of coral communities that are fully acclimatized to elevated CO2, we compared the relative success of coral recruitment and later life stages at two volcanic CO2 seeps and adjacent control sites in Papua New Guinea. Our field experiments showed that the effects of ocean acidification (OA) on coral recruitment rates were up to an...
Data from: Naturally occurring hybrids of coral reef butterflyfishes have similar fitness compared to parental speciesStefano R. Montanari, Jean-Paul A. Hobbs, Morgan S. Pratchett, Line K. Bay & Lynne Van Herwerden
Hybridisation can produce evolutionary novelty by increasing fitness and adaptive capacity. Heterosis, or hybrid vigour, has been documented in many plant and animal taxa, and is a notable consequence of hybridisation that has been exploited for decades in agriculture and aquaculture. On the contrary, loss of fitness in naturally occurring hybrid taxa has been observed in many cases. This can have negative consequences for the parental species involved (wasted reproductive effort), and has raised concerns...
Data from: Sibling species of mutualistic Symbiodinium clade G from bioeroding sponges in the western Pacific and western Atlantic oceansBlake D. Ramsby, Malcolm S. Hill, Daniel J. Thornhill, Sieuwkje F. Steenuizen, Michelle Achlatis, Allison M. Lewis, Todd C. LaJeunesse & Sieuwkje F. Steenhuizen
Dinoflagellates in the genus Symbiodinium associate with a broad array of metazoan and protistian hosts. Symbiodinium-based symbioses involving bioeroding sponge hosts have received less attention than those involving scleractinian hosts. Certain species of common Cliona harbor high densities of an ecologically restricted group of Symbiodinium, referred to as Clade G. The relationships of these unusual Clade G Symbiodinium with Foraminifera, sponges, and black coral (Antipatharia) are rarely studied. Nonetheless, analyses of genetic evidence indicate that...
Data from: Seagrass ecosystems reduce exposure to bacterial pathogens of humans, fishes and invertebratesJoleah B. Lamb, Jeroen A. J. M. Van De Water, David G. Bourne, Craig Altier, Margaux Y. Hein, Evan A. Fiorenza, Nur Abu, Jamaluddin Jompa & C. Drew Harvell
Plants are important in urban environments for removing pathogens and improving water quality. Seagrass meadows are the most widespread coastal ecosystem on the planet. Although these plants are known to be associated with natural biocide production, they have not been evaluated for their ability to remove microbiological contamination. Using amplicon sequencing of the 16S ribosomal RNA gene, we found that when seagrass meadows are present, there was a 50% reduction in the relative abundance of...
1. Partitioning energy between critical basal functions and activity-associated behaviours is a primary determinant of animal survival. Consequently, habitat selection is likely to be driven by the efficiency with which resources can be acquired from a heterogeneous energy landscape. 2. Determining how energy partitioning is achieved across temporal and spatial scales is particularly challenging in aquatic animals due to the logistical limitations in estimating field metabolic rates (FMR) while simultaneously examining habitat choice. 3. Here,...
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits...
Data from: Functional genomic analysis of corals from natural CO2-seeps reveals core molecular responses involved in acclimatization to ocean acidificationCarly D. Kenkel, Aurelie Moya, Julia Strahl, Craig Humphrey & Line K. Bay
Little is known about the potential for acclimatization or adaptation of corals to ocean acidification and even less about the molecular mechanisms underpinning these processes. Here we examine global gene expression patterns in corals and their intracellular algal symbionts from two replicate population pairs in Papua New Guinea that have undergone long-term acclimatization to natural variation in pCO2. In the coral host, only 61 genes were differentially expressed in response to pCO2 environment, but the...
