Background: Scabies is endemic in many Aboriginal and Torres Strait Islander communities, with 69% of infants infected in the first year of life. We report the outcomes against scabies of two oral ivermectin mass drug administrations (MDAs) delivered 12 months apart in a remote Australian Aboriginal community. Methods: Utilizing a before and after study design, we measured scabies prevalence through population census with sequential MDAs at baseline and month 12. Surveys at months 6 and...

Data from: Strategies for understanding and reducing the Plasmodium vivax and Plasmodium ovale hypnozoite reservoir in Papua New Guinean children: a randomised placebo-controlled trial and mathematical model

Leanne J. Robinson, Rahel Wampfler, Inoni Betuela, Stephan Karl, Michael T. White, Connie S. N. Li Wai Suen, Natalie E. Hofmann, Benson Kiniboro, Andreea Waltmann, Jessica Brewster, Lina Lorry, Nandao Tarongka, Lornah Samol, Mariabeth Silkey, Quique Bassat, Peter M. Siba, Louis Schofield, Ingrid Felger, Ivo Mueller & Benson Kinboro
Background: The undetectable hypnozoite reservoir for relapsing Plasmodium vivax and P. ovale malarias presents a major challenge for malaria control and elimination in endemic countries. This study aims to directly determine the contribution of relapses to the burden of P. vivax and P. ovale infection, illness, and transmission in Papua New Guinean children. Methods and Findings: From 17 August 2009 to 20 May 2010, 524 children aged 5–10 y from East Sepik Province in Papua...

Data from: Why pair? Evidence of aggregative mating in a socially monogamous marine fish (Siganus doliatus, Siganidae)

Rebecca J. Fox, David R. Bellwood & Michael D. Jennions
Many species live in stable pairs, usually to breed and raise offspring together, but this cannot be assumed. Establishing whether pairing is based on mating, or an alternative cooperative advantage, can be difficult, especially where species show no obvious sexual dimorphism and where the act of reproduction itself is difficult to observe. In the tropical marine fishes known as rabbitfish (Siganidae), half of extant species live in socially monogamous, territorial pairs. It has been assumed...

Data from: The effects of background risk on behavioural lateralization in a coral reef fish

Maud C. O. Ferrari, Mark I. McCormick, Bridie J. M. Allan, Rebecca B. Choi, Ryan Ramasamy, Douglas P. Chivers, Ryan A. Ramasamy & Maud C.O. Ferrari
Behavioural lateralization – the preferential use of one side of the body or either of the bilateral organs or limbs – has been well documented in many species, in a number of contexts. While the benefits reported are numerous, existing latent variability in the degree of lateralization within and across populations, species and taxa indicates that existing costs may modulate its expression. Few studies have reported changes in the degree of lateralization at the individual...

Data from: Ocean acidification boosts larval fish development but reduces the window of opportunity for successful settlement

Tullio Rossi, Ivan Nagelkerken, Stephen D. Simpson, Jennifer C.A. Pistevos, Sue-Ann Watson, Laurene Merillet, Peter Fraser, Philip L. Munday & Sean D. Connell
Locating appropriate settlement habitat is a crucial step in the life cycle of most benthic marine animals. In marine fish, this step involves the use of multiple senses, including audition, olfaction and vision. To date, most investigations of fish audition focus on the hearing thresholds to various frequencies of sounds without testing an ecological response to such sounds. Identifying responses to biologically relevant sounds at the development stage in which orientation is most relevant is...

Data from: Climate mediates the effects of disturbance on ant assemblage structure

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Simon Watson, Manoli Photakis, Silvia Abril, Alan N. Andersen, Elena Angulo, Inge Armbrecht, Xavier Arnan, Fabricio B. Baccaro, Tom R. Bishop, Raphael Boulay, Cristina Castracani, Israel Del Toro, Thibaut Delsinne, Mireia Diaz, David A. Donoso, Martha L. Enríquez, Tom M. Fayle, Donald H. Feener, Matthew C. Fitzpatrick, Crisanto Gómez, Donato A. Grasso, Sarah Groc … & C. Gomez
Many studies have focused on the impacts of climate change on biological assemblages, yet little is known about how climate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness and evenness were associated positively with temperature, and negatively with disturbance. However, the interaction...

Data from: Unexpected cryptic species diversity in the widespread coral Seriatopora hystrix masks spatial-genetic patterns of connectivity

Patricia A. Warner, Madeleine J. H. Van Oppen & Bette L. Willis
Mounting evidence of cryptic species in a wide range of taxa highlights the need for careful analyses of population genetic data sets to unravel within-species diversity from potential interspecies relationships. Here, we use microsatellite loci and hierarchical clustering analysis to investigate cryptic diversity in sympatric and allopatric (separated by 450 km) populations of the widespread coral Seriatopora hystrix on the Great Barrier Reef. Structure analyses delimited unique genetic clusters that were confirmed by phylogenetic and...

Data from: Root effect haemoglobins in fish may greatly enhance general oxygen delivery relative to other vertebrates

Jodie L. Rummer & Colin J. Brauner
The teleost fishes represent over half of all extant vertebrates; they occupy nearly every body of water and in doing so, occupy a diverse array of environmental conditions. We propose that their success is related to a unique oxygen (O2) transport system involving their extremely pH-sensitive haemoglobin (Hb). A reduction in pH reduces both Hb-O2 affinity (Bohr effect) and carrying capacity (Root effect). This, combined with a large arterial-venous pH change (ΔpHa-v) relative to other...

Data from: Photosynthetic pathways in Bromeliaceae: phylogenetic and ecological significance of CAM and C3 based on carbon isotope ratios for 1893 species

Darren M. Crayn, Klaus Winter, Katharina Schulte & J. Andrew C. Smith
A comprehensive analysis of photosynthetic pathways in relation to phylogeny and elevational distribution was conducted in Bromeliaceae, an ecologically diverse Neotropical family containing large numbers of both terrestrial and epiphytic species. Tissue carbon isotope ratio (δ13C) was used to determine the occurrence of crassulacean acid metabolism (CAM) and C3 photosynthesis in 1893 species, representing 57% of species and all 56 genera in the family. The frequency of δ13C values showed a strongly bimodal distribution: 1074...

Data from: Impacts and recovery from Severe Tropical Cyclone Yasi on the Great Barrier Reef

Roger J. Beeden, Jeffrey Maynard, Marjetta Puotinen, Paul Marshall, Jen Dryden, Jeremy Goldberg, Gareth Williams & Roger Beeden
Full recovery of coral reefs from tropical cyclone (TC) damage can take decades, making cyclones a major driver of habitat condition where they occur regularly. Since 1985, 44 TCs generated gale force winds (≥17 metres/second) within the Great Barrier Reef Marine Park (GBRMP). Of the hurricane strength TCs (≥H1—Saffir Simpson scale; ≥ category 3 Australian scale), TC Yasi (February, 2011) was the largest. In the weeks after TC Yasi crossed the GBRMP, participating researchers, managers...

Data from: Connectivity in grey reef sharks (Carcharhinus amblyrhynchos) determined using empirical and simulated genetic data

Paolo Momigliano, Robert Harcourt, William D. Robbins & Adam Stow
Grey reef sharks (Carcharhinus amblyrhynchos) can be one of the numerically dominant high order predators on pristine coral reefs, yet their numbers have declined even in the highly regulated Australian Great Barrier Reef (GBR) Marine Park. Knowledge of both large scale and fine scale genetic connectivity of grey reef sharks is essential for their effective management, but no genetic data are yet available. We investigated grey reef shark genetic structure in the GBR across a...

Data from: Human disease hinders anti-poaching efforts in Indian nature reserves

Nandini Velho, Umesh Srinivasan, N. S. Prashanth, William F. Laurance & N.S. Prashanth
Where hunting pressure is high, anti-poaching efforts are often crucial for protecting native wildlife populations in nature reserves. However, many reserves suffer from inadequate support and provisioning of staff, especially in developing nations. In Pakke Tiger Reserve in northeastern India, we found that malarial infection is a serious hindrance for front-line patrolling staff that limits the time they can spend in the field. We assessed the consequences of malaria both for local people and park...

Data from: Lineage range estimation method reveals fine-scale endemism linked to Pleistocene stability in Australian rainforest herpetofauna

Dan F. Rosauer, Renee A. Catullo, Jeremy VanDerWal, Adnan Moussalli & Craig Moritz
Areas of suitable habitat for species and communities have arisen, shifted, and disappeared with Pleistocene climate cycles, and through this shifting landscape, current biodiversity has found paths to the present. Evolutionary refugia, areas of relative habitat stability in this shifting landscape, support persistence of lineages through time, and are thus crucial to the accumulation and maintenance of biodiversity. Areas of endemism are indicative of refugial areas where diversity has persisted, and endemism of intraspecific lineages...

Data from: Quantifying network resilience: comparison before and after a major perturbation shows strengths and limitations of network metrics

Christine Moore, Graeme S. Cumming & John Grewar
1. The resilience literature often assumes that social–ecological reorganization will result in either the removal of deficient system elements (components, interactions) or social learning. Major perturbations are expected to lead to either adaptation or, if accompanied by a regime shift, transformation. This has led to a conflation of the concepts of resilience and adaptation, which has in turn made it difficult to quantitatively distinguish between cases in which a system returned to a previous state,...

Data from: Susceptibility of amphibians to chytridiomycosis is associated with MHC class II conformation

Arnaud Bataille, Scott D. Cashins, Laura Grogan, Lee F. Skerratt, David Hunter, Michael McFaddan, Benjamin Scheele, Laura A. Brannelly, Amy Macris, Peter S. Harlow, Sara Bell, Lee Berger & Bruce Waldman
The pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd) can cause precipitous population declines in its amphibian hosts. Responses of individuals to infection vary greatly with the capacity of their immune system to respond to the pathogen. We used a combination of comparative and experimental approaches to identify major histocompatibility complex class II (MHC-II) alleles encoding molecules that foster the survival of Bd-infected amphibians. We found that Bd-resistant amphibians across four continents share common amino acids in...

Data from: Polymorphism and division of labour in a socially complex ant: neuromodulation of aggression in the Australian weaver ant, Oecophylla smaragdina

J. Frances Kamhi, Kelley Nunn, Simon K. A. Robson & James F. A. Traniello
Complex social structure in eusocial insects can involve worker morphological and behavioural differentiation. Neuroanatomical variation may underscore worker division of labour, but the regulatory mechanisms of size-based task specialization in polymorphic species are unknown. The Australian weaver ant, Oecophylla smaragdina, exhibits worker polyphenism: larger major workers aggressively defend arboreal territories, whereas smaller minors nurse brood. Here, we demonstrate that octopamine (OA) modulates worker size-related aggression in O. smaragdina. We found that the brains of majors...

Data from: Environmental gradients and the evolution of successional habitat specialization: a test case with 14 Neotropical forest sites

Susan G. Letcher, Jesse R. Lasky, Robin L. Chazdon, Natalia Norden, S. Joseph Wright, Jorge A. Meave, Eduardo A. Pérez-García, Rodrigo Muñoz, Eunice Romero-Pérez, Ana Andrade, José Luis Andrade, Patricia Balvanera, Justin M. Becknell, Tony V. Bentos, Radika Bhaskar, Frans Bongers, Vanessa Boukili, Pedro H. S. Brancalion, Ricardo G. César, Deborah A. Clark, David B. Clark, Dylan Craven, Alexander DeFrancesco, Juan M. Dupuy, Bryan Finegan … & G. Bruce Williamson
1. Successional gradients are ubiquitous in nature, yet few studies have systematically examined the evolutionary origins of taxa that specialize at different successional stages. Here we quantify successional habitat specialization in Neotropical forest trees and evaluate its evolutionary lability along a precipitation gradient. Theoretically, successional habitat specialization should be more evolutionarily conserved in wet forests than in dry forests due to more extreme microenvironmental differentiation between early and late successional stages in wet forest. 2....

Data from: Seascape genetics along environmental gradients in the Arabian Peninsula: insights from ddRAD sequencing of anemonefishes

Pablo 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: Application of wMelPop Wolbachia strain to crash local populations of Aedes aegypti

Scott A. Ritchie, Michael Townsend, Chris J. Paton, Ashley G. Callahan & Ary A. Hoffmann
The endosymbiotic bacteria Wolbachia pipientis (wMel strain) has been successfully established in several populations of Aedes aegypti, the primary dengue vector. The virulent Wolbachia strain wMelPop is known to cause several pathological impacts (increased egg mortality, life shortening, etc.) reducing overall fitness in the mosquito Ae. aegypti. Increased egg mortality could substantially reduce egg banks in areas with a lengthy monsoonal dry season, and be employed to eliminate local populations. We tested this application under...

Data from: Divergent effects of forest edges on host distribution and seed disperser activity influence mistletoe distribution and recruitment

Ainhoa Magrach, Javier Rodriguez-Perez, Martin Piazzon & Luis Santamaria
1. Species interactions define functional diversity and community stability across ecosystems, and depend on the spatial distribution, the habitat requirements, and the sensitivity to disturbances of all interacting partners. Hence, assessing the effects of such anthropogenic disturbances on multi-species interactions may be essential to improve adaptation and mitigation measures for biodiversity conservation. 2. We determined the importance of edge effects on the interaction and distribution of three keystone species in South American temperate rainforests: the...

Data from: The role of marine reserves in the replenishment of a locally-impacted population of anemonefish on the Great Barrier Reef

Mary 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...

Data from: Exploring the nature of ecological specialization in a coral reef fish community: morphology, diet, and foraging microhabitat use

Simon J. Brandl, William D. Robbins & David R. Bellwood
Patterns of ecological specialization offer invaluable information about ecosystems. Yet, specialization is rarely quantified across several ecological niche axes and variables beyond the link between morphological and dietary specialization have received little attention. Here, we provide a quantitative evaluation of ecological specialization in a coral reef fish assemblage (f. Acanthuridae) along one fundamental and two realized niche axes. Specifically, we examined ecological specialization in 10 surgeonfish species with regards to morphology and two realized niche...

Data from: Large mammal use of protected and community-managed lands in a biodiversity hotspot

Nandini Velho, Umesh Srinivasan, Priya Singh & William F. Laurance
In large parts of the biodiversity-rich tropics, various forest governance regimes often coexist, ranging from governmental administration to highly decentralized community management. Two common forms of such governance are protected areas, and community lands open to limited resource extraction. We studied wildlife occurrences in the north-east Indian state of Arunachal Pradesh, where the Eaglenest Wildlife Sanctuary (EWS) is situated adjacent to community lands governed by the Bugun and Sherdukpen tribes. We conducted transect-based mammal sign...

Data from: Lifespan behavioral and neural resilience in a social insect

Ysabel Milton Giraldo, J. Frances Kamhi, Vincent Fourcassié, Mathieu Moreau, Simon K. A. Robson, Adina Rusakov, Lindsey Wimberly, Alexandria Diloreto, Adrianna Kordek & James F. A. Traniello
Analyses of senescence in social species are important to understanding how group living influences the evolution of ageing in society members. Social insects exhibit remarkable lifespan polyphenisms and division of labour, presenting excellent opportunities to test hypotheses concerning ageing and behaviour. Senescence patterns in other taxa suggest that behavioural performance in ageing workers would decrease in association with declining brain functions. Using the ant Pheidole dentata as a model, we found that 120-day-old minor workers,...

Data from: NetView P: a network visualization tool to unravel complex population structure using genome-wide SNPs

Eike J. Steinig, Markus Neuditschko, Mehar S. Khatkar, Herman W. Raadsma & Kyall R. Zenger
Network-based approaches are emerging as valuable tools for the analysis of complex genetic structure in both wild and captive populations. NetView P combines data quality control with the construction of population networks based on mutual k-nearest-neighbours thresholds applied to genome-wide SNPs. The program is cross-platform compatible, open-source and efficiently operates on data ranging from hundreds to hundreds of thousands of SNPs through multiprocessing in Python. We used the pipeline for the analysis of pedigree data...
