Data from: Temporal and spatial activity-associated energy partitioning in free-swimming sea snakes

Vinay Udyawer, Colin A. Simpfendorfer, Michelle R. Heupel & Timothy D. Clark
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,...

Data from: High intra-ocean, but limited inter-ocean genetic connectivity in populations of the deep-water oblique-banded snapper Pristipomoides zonatus (Pisces: Lutjanidae)

W. Jason Kennington, Peter W. Keron, Euan S. Harvey, Corey B. Wakefield, Ashley J. Williams, Tuikolongahau Halafihi & Stephen J. Newman
While many studies have investigated connectivity and subdivision in marine fish occupying tropical, shallow water reef habitats, relatively few have been conducted on commercially important deep-water species in the Indo-Pacific region. Here, we examine spatial and temporal genetic variation in the deep-water oblique-banded snapper Pristipomoides zonatus, collected from eight locations across the Indian and Pacific Oceans. A total of 292 individuals were screened for genetic variation at six nuclear microsatellite loci and the cytochrome c...

Data from: Seagrass ecosystems reduce exposure to bacterial pathogens of humans, fishes and invertebrates

Joleah 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...

Data from: Strong population structure deduced from genetics, otolith chemistry and parasite abundances explains vulnerability to localised fishery collapse in a large Sciaenid fish, Protonibea diacanthus

Laura Taillebois, Diane P. Barton, David A. Crook, Thor Saunders, Jonathan Taylor, Mark Hearnden, Richard J. Saunders, Stephen J. Newman, Michael J. Travers, David J. Welch, Alan Greig, Christine Dudgeon, Safia Maher & Jennifer R. Ovenden
As pressure on coastal marine resources is increasing globally, the need to quantitatively assess vulnerable fish stocks is crucial in order to avoid the ecological consequences of stock depletions. Species of Sciaenidae (croakers, drums) are important components of tropical and temperate fisheries and are especially vulnerable to exploitation. The black-spotted croaker, Protonibea diacanthus, is the only large sciaenid in coastal waters of northern Australia where it is targeted by commercial, recreational and indigenous fishers due...

Data from: Functional genomic analysis of corals from natural CO2-seeps reveals core molecular responses involved in acclimatization to ocean acidification

Carly 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...

Christopher Stephen Bird, Ana Veríssimo, Sarah Magozzi, Kátya G. Abrantes, Alex Aguilar, Hassan Al-Reasi, Adam Barnett, Dana M. Bethea, Gérard Biais, Asuncion Borrell, Marc Bouchoucha, Mariah Boyle, Edward J. Brooks, Juerg Brunnschweiler, Paco Bustamante, Aaron Carlisle, Diana Catarino, Stéphane Caut, Yves Cherel, Tiphaine Chouvelon, Diana Churchill, Javier Ciancio, Julien Claes, Ana Colaço, Dean L. Courtney … & Clive N. Trueman
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: Strong trans-Pacific break and local conservation units in the Galapagos shark (Carcharhinus galapagensis) revealed by genome-wide cytonuclear markers

Diana A. Pazmiño, Gregory E. Maes, Madeline E. Green, Colin A. Simpfendorfer, Mauricio Hoyos-Padilla, Clinton J.A. Duffy, Carl G. Meyer, Sven E. Kerwath, Pelayo Salinas-De-León & Lynne Van Herwerden
The application of genome-wide cytonuclear molecular data to identify management and adaptive units at various spatio-temporal levels is particularly important for overharvested large predatory organisms, often characterized by smaller, localized populations. Despite being “near threatened”, current understanding of habitat use and population structure of Carcharhinus galapagensis is limited to specific areas within its distribution. We evaluated population structure and connectivity across the Pacific Ocean using genome-wide Single Nucleotide Polymorphisms (~7200 SNPs) and mitochondrial Control Region...

Data from: Effects of hypoxia and ocean acidification on the upper thermal niche boundaries of coral reef fishes

Rasmus Ern, Jacob L. Johansen, Jodie L. Rummer & Andrew J. Esbaugh
Rising ocean temperatures are predicted to cause a poleward shift in the distribution of marine fishes occupying the extent of latitudes tolerable within their thermal range boundaries. A prevailing theory suggests that the upper thermal limits of fishes are constrained by hypoxia and ocean acidification. However, some eurythermal fish species do not conform to this theory, and maintain their upper thermal limits in hypoxia. Here we determine if the same is true for stenothermal species....

Data from: Arboreality increases reptile community resistance to disturbance from livestock grazing

Heather Neilly, Eric J. Nordberg, Jeremy VanDerWal & Lin Schwarzkopf
Domestic livestock grazing directly alters ground-level habitat but its effects on arboreal habitat are poorly known. Similarly, the response to grazing of ground-dwelling fauna has been examined, but there are few studies of arboreal fauna. Globally, grazing has been implicated in the decline of vertebrate fauna species, but some species appear resistant to the effects of grazing, either benefiting from the structural changes at ground level or avoiding them, as may be the case with...

Data from: Decoupled diversification dynamics of feeding morphology following a major functional innovation in marine butterflyfishes

Nicolai Konow, Samantha Price, Rickard Abom, David Bellwood, Peter Wainwright & Richard Abom
The diversity of fishes on coral reefs is influenced by the evolution of feeding innovations. For instance, the evolution of an intramandibular jaw joint has aided shifts to corallivory in Chaetodon butterflyfishes following their Miocene colonization of coral reefs. Today, over half of all Chaetodon species consume coral, easily the largest concentration of corallivores in any reef fish family. In contrast with Chaetodon, other chaetodontids, including the long-jawed bannerfishes, remain less intimately associated with coral...

Data from: Heritability of behavioural tolerance to high CO2 in a coral reef fish is masked by non-adaptive phenotypic plasticity

Megan J. Welch & Philip L. Munday
Previous studies have demonstrated limited potential for acclimation of adversely affected olfactory behaviours in reef fishes under elevated CO2, indicating that genetic adaptation will be required to maintain behavioural performance in the future. Adaptation depends on the presence of heritable phenotypic variation in the trait, which may differ between populations and environments. We used parent-offspring regressions to estimate the heritability (h2) of variation in behavioural tolerance to high CO2 (754 μatm) in both field-collected and...

Data from: Changes in predator exposure, but not diet induce phenotypic plasticity in scorpion venom

Alex N. Gangur, Michael Smout, Michael J. Liddell, Jamie E. Seymour, David Wilson & Tobin D. Northfield
Animals embedded between trophic levels must simultaneously balance pressures to deter predators and acquire resources. Venomous animals may use venom toxins to mediate both pressures, and thus changes in this balance may alter the composition of venoms. Basic theory suggests that greater exposure to a predator should induce a larger proportion of defensive venom components relative to offensive venom components, while increases in arms races with prey will elicit the reverse. Alternatively, reducing the need...

Data from: Widespread ecomorphological convergence in multiple fish families spanning the marine–freshwater interface

Aaron M. Davis & Ricardo Betancur-R
The theoretical definition and quantification of convergence is an increasingly topical focus in evolutionary research, with particular growing interest on study scales spanning deep phylogenetic divergences and broad geographical areas. While much progress has recently been made in understanding the role of convergence in driving terrestrial (e.g. anole lizards) and aquatic (e.g. cichlids) radiations, little is known about its macroevolutionary effects across environmental gradients. This study uses a suite of recently developed comparative approaches integrating...

Data from: Intraspecific variation in climate-relevant traits in a tropical rainforest lizard

John Llewelyn, Stewart L. Macdonald, Amberlee Hatcher, Craig Moritz & Ben L. Phillips
Aim The exceptionally rich biodiversity found in tropical rainforest is under threat from anthropogenic climate change. We recognize the threat, yet we have little knowledge of the capacity of tropical species to adjust their climate sensitivity in response to it. One indicator of a species’ capacity to adjust to different climates is the amount of intraspecific variation observed in its climate-relevant traits; if a climate-relevant trait varies, and this variation is correlated with local climates,...

Data from: Morphological diversification of ampullariid gastropods (Nsungwe Formation, late Oligocene, Rukwa Rift Basin, Tanzania) is coincident with onset of East African rifting

Y. Ranjeev Epa, Alycia L. Stigall, Eric M. Roberts, Haley D. O'Brien & Nancy J. Stevens
A new freshwater gastropod fauna is described from the late Oligocene Nsungwe Formation of the Rukwa Rift Basin, Tanzania. Six new species of ampullariids are established including five species of Lanistes (L. microovum, L. nsungwensis, L. songwellipticus, L. songweovum and L. rukwaensis) and one species of Carnevalea (C. santiapillai). These taxa occupy a morphospace region comparable to nearly half of extant Lanistes, a common and widespread genus in Africa and Madagascar. Palaeoecological evidence indicates that...

Data from: Widespread hybridization and bidirectional introgression in sympatric species of coral reef fish

Hugo B. Harrison, Michael L. Berumen, Pablo Saenz-Agudelo, Eva Salas, David H. Williamson & Geoffrey P. Jones
Coral reefs are highly diverse ecosystems, where numerous closely related species often coexist. How new species arise and are maintained in these high geneflow environments have been long-standing conundrums. Hybridization and patterns of introgression between sympatric species provide a unique insight into the mechanisms of speciation and the maintenance of species boundaries. In this study, we investigate the extent of hybridization between two closely related species of coral reef fish: the common coral trout (Plectropomus...

Data from: Quantifying apart what belongs together: a multi-state species distribution modeling framework for species using distinct habitats

Veronica F. Frans, Amélie A. Augé, Hendrik A. Edelhoff, Stefan Erasmi, Niko Balkenhol, Jan O. Engler & Hendrik Edelhoff
1. Species distribution models (SDMs) have been used to inform scientists and conservationists about the status and change of occurrence patterns in threatened species. Many mobile species use multiple functionally distinct habitats, and cannot occupy one habitat type without the other being within a reachable distance. For such species, classical applications of SDMs might lead to erroneous representations of habitat suitability, as the complex relationships between predictors are lost when merging occurrence information across multiple...

Data from: A low-cost solution for documenting distribution and abundance of endangered marine fauna and impacts from fisheries

Nicolas J. Pilcher, Kanjana Adulyanukosol, Himansu Das, Patricia Davis, Ellen Hines, Donna Kwan, Helene Marsh, Louisa Ponnampalam & John Reynolds
Fisheries bycatch is a widespread and serious issue that leads to declines of many important and threatened marine species. However, documenting the distribution, abundance, population trends and threats to sparse populations of marine species is often beyond the capacity of developing countries because such work is complex, time consuming and often extremely expensive. We have developed a flexible tool to document spatial distribution and population trends for dugongs and other marine species in the form...

Data from: Demonstrating multiple benefits from periodically harvested fisheries closures

Jordan S. Goetze, Joachim Claudet, Fraser Januchowski-Hartley, Timothy J. Langlois, Shaun K. Wilson, Crow White, Rebecca Weeks & Stacy D. Jupiter
1.Periodically harvested closures (PHCs) are one of the most common forms of fisheries management in Melanesia, demonstrating multiple objectives, including sustaining fish stocks and increasing catch efficiency to support small-scale fisheries. No studies have comprehensively assessed their ability to provide short-term fisheries benefits across the entire harvest regime. 2.We present a novel analytical framework to guide a meta-analysis and assist future research in conceptualizing and assessing the potential of PHCs to deliver benefits for multiple...

Data from: Idiosyncratic responses to climate-driven forest fragmentation and marine incursions in reed frogs from Central Africa and the Gulf of Guinea Islands

Rayna C. Bell, Juan L. Parra, Gabriel Badjedjea, Michael F. Barej, David C. Blackburn, Marius Burger, Alan Channing, J. Maximilian Dehling, Eli Greenbaum, Václav Gvoždík, Jos Kielgast, Chifundera Kusamba, Stefan Lötters, Patrick J. McLaughlin, Zoltán T. Nagy, Mark-Oliver Rödel, Daniel M. Portik, Bryan L. Stuart, Jeremy VanDerWal, Ange-Ghislain Zassi Boulou & Kelly R. Zamudio
Organismal traits interact with environmental variation to mediate how species respond to shared landscapes. Thus, differences in traits related to dispersal ability or physiological tolerance may result in phylogeographic discordance among co-distributed taxa, even when they are responding to common barriers. We quantified climatic suitability and stability, and phylogeographic divergence within three reed frog species complexes across the Guineo-Congolian forests and Gulf of Guinea archipelago of Central Africa to investigate how they responded to a...

Data from: Efficiency of ddRAD target enriched sequencing across spiny rock lobster species (Palinuridae: Jasus)

Carla A. Souza, Nicholas Murphy, Cecilia Villacorta-Rath, Laura N. Woodings, Irina Ilyushkina, Cristian E. Hernandez, Bridget S. Green, James J. Bell & Jan M. Strugnell
Double digest restriction site-associated DNA sequencing (ddRADseq) and target capture sequencing methods are used to explore population and phylogenetic questions in non-model organisms. ddRADseq offers a simple and reliable protocol for population genomic studies, however it can result in a large amount of missing data due to allelic dropout. Target capture sequencing offers an opportunity to increase sequencing coverage with little missing data and consistent orthologous loci across samples, although this approach has generally been...

Data from: The role of topography and plant functional traits in determining tropical reforestation success

Alexander W. Cheesman, Noel D. Preece, Penny Van Oosterzee, Peter D. Erskine & Lucas A. Cernusak
1.Early establishment and sapling growth is a key phase in ensuring cost-effective reforestation success in relation to biodiversity outcomes. Therefore species selection must consider the interaction between plant functional traits and the often-challenging and heterogeneous biophysical environment of degraded landscapes. 2.In this study, we examine how microtopography (slope) results in spatial heterogeneity of soil nutrients, especially phosphorus (P) in a degraded tropical pasture landscape in Queensland, Australia. We then explore how this small-scale heterogeneity influences...

Data from: Kin recognition in embryonic damselfishes

Jennifer Ann Atherton & Mark Ian McCormick
Predator-induced mortality rates are highest in early life stages; therefore, early recognition of threats can greatly increase survival chances. Some species of coral reef fishes have been frequently found to recruit back to their natal reefs; in this instance, there is a high chance of juveniles encountering their siblings, among other kin, after hatching. Kin recognition plays an important ecological role in that it allows individuals to protect genetically similar relatives, and hence increase their...

Data from: Disentangling the pathways of land use impacts on the functional structure of fish assemblages in Amazon streams

Rafael P. Leitão, Jansen Zuanon, David Mouillot, Cecília G. Leal, Robert M. Hughes, Philip R. Kaufmann, Sébastien Villéger, Paulo S. Pompeu, Daniele Kasper, Felipe R. De Paula, Silvio F. B. Ferraz & Toby A. Gardner
Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approaches, and illustrates the need for more in-depth studies to assess the mechanisms that determine changes in stream biodiversity. Here we present results of the most comprehensive multi-scale assessment of the biological condition of streams in the...
