Data from: Seascape genetics along environmental gradients in the Arabian Peninsula: insights from ddRAD sequencing of anemonefishesPablo Saenz-Agudelo, Joseph D. DiBattista, Marek J. Piatek, Michelle R. Gaither, Hugo B. Harrison, Gerrit B. Nanninga & Michael L. Berumen
Understanding the processes that shape patterns of genetic structure across space is a central aim of landscape genetics. However, it remains unclear how geographic features and environmental variables shape gene flow, particularly for marine species in large complex seascapes. Here, we evaluated the genomic composition of the two-band anemonefish Amphiprion bicinctus across its entire geographic range in the Red Sea and Gulf of Aden, as well as its close relative, Amphiprion omanensis endemic to the...
Data from: Sensitivity and acclimation of three canopy-forming seaweeds to UVB radiation and warmingXi Xiao, Thibaut De Bettignies, Ylva S. Olsen, Susana Agusti, Carlos M. Duarte & Thomas Wernberg
Canopy-forming seaweeds, as primary producers and foundation species, provide key ecological services. Their responses to multiple stressors associated with climate change could therefore have important knock-on effects on the functioning of coastal ecosystems. We examined interactive effects of UVB radiation and warming on juveniles of three habitat-forming subtidal seaweeds from Western Australia–Ecklonia radiata, Scytothalia dorycarpa and Sargassum sp. Fronds were incubated for 14 days at 16–30°C with or without UVB radiation and growth, health status,...
Although whale sharks (Rhincodon typus) have been documented to move thousands of kilometres, they are most frequently observed at a few predictable seasonal aggregation sites. The absence of sharks at the surface during visual surveys has led to the assumption that sharks disperse to places unknown during the long ‘off-seasons’ at most of these locations. Here we compare 2 years of R. typus visual sighting records from Mafia Island in Tanzania to concurrent acoustic telemetry...
Data from: Exploring seascape genetics and kinship in the reef sponge Stylissa carteri in the Red SeaEmily C. Giles, Pablo Saenz-Agudelo, Nigel E. Hussey, Timothy Ravasi & Michael L. Berumen
A main goal of population geneticists is to study patterns of gene flow to gain a better understanding of the population structure in a given organism. To date most efforts have been focused on studying gene flow at either broad scales to identify barriers to gene flow and isolation by distance or at fine spatial scales in order to gain inferences regarding reproduction and local dispersal. Few studies have measured connectivity at multiple spatial scales...
Data from: A quantitative genetic approach to assess the evolutionary potential of a coastal marine fish to ocean acidificationAlex J. Malvezzi, Christopher S. Murray, Kevin A. Feldheim, Joseph D. DiBattista, Dany Garant, Christopher J. Gobler, Demian D. Chapman & Hannes Baumann
Assessing the potential of marine organisms to adapt genetically to increasing oceanic CO2 levels requires proxies such as heritability of fitness-related traits under ocean acidification (OA). We applied a quantitative genetic method to derive the first heritability estimate of survival under elevated CO2 conditions in a metazoan. Specifically, we reared offspring, selected from a wild coastal fish population (Atlantic silverside, Menidia menidia), at high CO2 conditions (~2,300 μatm) from fertilization to 15 days post hatch,...
The northwestern Indian Ocean harbors a number of larger marine vertebrate taxa that warrant the investigation of genetic population structure given remarkable spatial heterogeneity in biological characteristics such as distribution, behavior, and morphology. Here, we investigate the genetic population structure of four commercially exploited shark species with different biological characteristics (Carcharhinus limbatus, Carcharhinus sorrah, Rhizoprionodon acutus, and Sphyrna lewini) between the Red Sea and all other water bodies surrounding the Arabian Peninsula. To assess intraspecific...
Data from: The role of marine reserves in the replenishment of a locally-impacted population of anemonefish on the Great Barrier ReefMary C. Bonin, Hugo B. Harrison, David H. Williamson, Ashley J. Frisch, Pablo Saenz-Agudelo, Michael L. Berumen & Geoffrey P. Jones
The development of parentage analysis to track the dispersal of juvenile offspring has given us unprecedented insight into the population dynamics of coral reef fishes. These tools now have the potential to inform fisheries management and species conservation, particularly for small fragmented populations under threat from exploitation and disturbance. In this study we resolve patterns of larval dispersal for a population of the anemonefish Amphiprion melanopus in the Keppel Islands (southern Great Barrier Reef). Habitat...
