Data from: Characterising the ecological trade-offs throughout the early ontogeny of coral recruitment

Christopher Doropoulos, George Roff, Yves-Marie Bozec, Mirta Zupan, Johanna Werminghausen & Peter J. Mumby
Drivers of recruitment in sessile marine organisms are often poorly understood, due to the rapidly changing requirements experienced during early ontogeny. The complex suite of physical, biological, and ecological interactions beginning at larval settlement involves a series of trade-offs that influence recruitment success. For example, while cryptic settlement within complex microhabitats is a commonly observed phenomenon in sessile marine organisms, it is unclear whether trade-offs between competition in cryptic refuges and predation on exposed surfaces...

Data from: Social genetic and social environment effects on parental and helper care in a cooperatively breeding bird

Mark James Adams, Matthew R. Robinson, Maria-Elena Mannarelli, Ben Hatchwell & Ben J. Hatchwell
Phenotypes expressed in a social context are not only a function of the individual, but can also be shaped by the phenotypes of social partners. These social effects may play a major role in the evolution of cooperative breeding if social partners differ in the quality of care they provide and if individual carers adjust their effort in relation to that of other carers. When applying social effects models to wild study systems, it is...

Data from: Geomolecular dating and the origin of placental mammals

Matthew J. Phillips
In modern evolutionary divergence analysis the role of geological information extends beyond providing a timescale, to informing molecular rate variation across the tree. Here I consider the implications of this development. I use fossil calibrations to test the accuracy of models of molecular rate evolution for placental mammals, and reveal substantial misspecification associated with life history rate correlates. Adding further calibrations to reduce dating errors at specific nodes unfortunately tends to transfer underlying rate errors...

Data from: Assessing spatio-temporal priorities for species’ recovery in broad-scale dynamic landscapes

Truly Santika, Clive A. McAlpine, Daniel Lunney, Kerrie A. Wilson & Jonathan R. Rhodes
1. As threats to biodiversity from environmental change increase, assessing priorities for mitigation action becomes increasingly important. However, there have been few attempts to schedule actions across broad spatial extents that explicitly account for dynamic ecological processes and threats. 2. We combined a dynamic occupancy model with a decision analysis framework to spatially allocate multiple recovery actions to maximize species’ probability of occupancy under threats posed by climate and land-use change. We used the koala...

Data from: Adoption in eastern grey kangaroos: a consequence of misdirected care?

Wendy J. King, David M. Forsyth, Graeme Coulson & Marco Festa-Bianchet
Adoption is rare in animals and is usually attributed to kin selection. In a 6-year study of eastern grey kangaroos (Macropus giganteus), 11 of 326 juveniles were adopted. We detected eight adoptions by observing behavioural associations and nursing between marked mothers and young and three more by analysing the relatedness of mothers and young using microsatellite DNA. Four adoptions involved reciprocal switches and three were by mothers whose own pouch young were known to subsequently...

Data from: UV-B radiation interacts with temperature to determine animal performance

Ensiyeh Ghanizadeh Kazerouni, Craig E. Franklin & Frank Seebacher
The interaction between UV-B and temperature can modify the effects of climate variability on animal function because UV-B and increasing temperatures may increase reactive oxygen species (ROS) production and thereby impair animal performance. However, antioxidant enzyme activities are also increased at higher temperatures, which could counteract negative effects of increased ROS. Conversely, UV-B exposure at lower temperature can exacerbate the effects of ROS because of lower antioxidant enzyme activities. Phenotypes can be plastic to compensate...

Data from: Replicated analysis of the genetic architecture of quantitative traits in two wild great tit populations

Anna W. Santure, Jocelyn Poissant, Isabelle De Cauwer, Kees Van Oers, Matthew R. Robinson, John L. Quinn, Martien A. M. Groenen, Marcel E. Visser, Ben C. Sheldon & Jon Slate
Currently there is much debate on the genetic architecture of quantitative traits in wild populations. Is trait variation influenced by many genes of small effect or by a few genes of major effect? Where is additive genetic variation located in the genome? Do the same loci cause similar phenotypic variation in different populations? Great tits (Parus major) have been studied extensively in long-term studies across Europe, and consequently are considered an ecological 'model organism'. Recently,...

Data from: Towards automated annotation of benthic survey images: variability of human experts and operational modes of automation

Oscar Beijbom, Peter J. Edmunds, Chris Roelfsema, Jennifer Smith, David I. Kline, Benjamin Neal, Matthew J. Dunlap, Vincent Moriarty, Tung-Yung Fan, Chih-Jui Tan, Stephen Chan, Tali Treibitz, Anthony Gamst, B. Greg Mitchell, David Kriegman & Benjamin P. Neal
Global climate change and other anthropogenic stressors have heightened the need to rapidly characterize ecological changes in marine benthic communities across large scales. Digital photography enables rapid collection of survey images to meet this need, but the subsequent image annotation is typically a time consuming, manual task. We investigated the feasibility of using automated point-annotation to expedite cover estimation of the 17 dominant benthic categories from survey-images captured at four Pacific coral reefs. Inter- and...

Data from: Strong and stable geographic differentiation of swamp buffalo maternal and paternal lineages indicates domestication in the China/Indochina border region

Yi Zhang, Yongfang Lu, Marnoch Yindee, Kuan-Yi Li, Hsiao-Yun Kuo, Yu-Ten Ju, Shaohui Ye, , Qiang Li, Yachun Wang, Vu Chi Cuong, Lan Doan Pham, Bounthong Bouahom, Bingzhuang Yang, Xianwei Liang, Zhihua Cai, Dianne Vankan, Wallaya Manatchaiworakul, Nonglid Kowlim, Somphot Duangchantrasiri, Worawidh Wajjwalku, Ben Colenbrander, Yuan Zhang, Peter Beerli, Johannes A. Lenstra … & J. Stuart F. Barker
The swamp type of the Asian water buffalo is assumed to have been domesticated by about 4000 years BP, following the introduction of rice cultivation. Previous localizations of the domestication site were based on mitochondrial DNA (mtDNA) variation within China, accounting only for the maternal lineage. We carried out a comprehensive sampling of China, Taiwan, Vietnam, Laos, Thailand, Nepal and Bangladesh and sequenced the mtDNA Cytochrome b gene and control region and the Y-chromosomal ZFY,...

Data from: Why does offspring size affect performance? Integrating metabolic scaling with life-history theory

Amanda K. Pettersen, Craig R. White & Dustin J. Marshall
Within species, larger offspring typically outperform smaller offspring. While the relationship between offspring size and performance is ubiquitous, the cause of this relationship remains elusive. By linking metabolic and life-history theory, we provide a general explanation for why larger offspring perform better than smaller offspring. Using high-throughput respirometry arrays, we link metabolic rate to offspring size in two species of marine bryozoan. We found that metabolism scales allometrically with offspring size in both species: while...

Data from: Ocean acidification induces biochemical and morphological changes in the calcification process of large benthic foraminifera

Martina De Freitas Prazeres, Sven Uthicke, John M. Pandolfi & M. Prazeres
Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed to different pH conditions. We measured growth rates (surface area and buoyant weight) and Ca-ATPase and Mg-ATPase activities and calculated shell density using micro-computer tomography images. In A. lessonii, we detected a significant decrease in buoyant...

Data from: Reef flattening effects on total richness and species responses in the Caribbean

Steven P. Newman, Erik H. Meesters, Charlie S. Dryden, Stacey M. Williams, Cristina Sanchez, Peter J. Mumby, Nicholas V.C. Polunin & Nicholas V. C. Polunin
1. There has been ongoing flattening of Caribbean coral reefs with the loss of habitat having severe implications for these systems. Complexity and its structural components are important to fish species richness and community composition, but little is known about its role for other taxa or species-specific responses. 2. This study reveals the importance of reef habitat complexity and structural components to different taxa of macrofauna, total species richness, and individual coral and fish species...

Data from: Prioritizing management actions for invasive populations using cost, efficacy, demography, and expert opinion for 14 plant species worldwide

Natalie Z. Kerr, Peter W. J. Baxter, Roberto Salguero-Gomez, Glenda M. Wardle, Yvonne M. Buckley & Peter W.J. Baxter
Management of invasive populations is typically investigated case-by-case. Comparative approaches have been applied to single aspects of management, such as demography, with cost or efficacy rarely incorporated. We present an analysis of the ranks of management actions for 14 species in five countries that extends beyond the use of demography alone to include multiple metrics for ranking management actions, which integrate cost, efficacy and demography (cost-effectiveness) and managers’ expert opinion of ranks. We use content...

Data from: Sensitivity analysis of conservation targets in systematic conservation planning

Noam Levin, Tessa Mazor, Eran Brokovich, Pierre-Elie Jablon & Salit Kark
Systematic conservation planning has rapidly advanced in the past decade and has been increasingly incorporated in multiple studies and conservation projects. One of its requirements is a quantitative definition of conservation targets. While the Convention on Biological Diversity aims to expand the world's protected area network to 17% of the land surface, in many cases such uniform policy-driven targets may not be appropriate for achieving persistence of various species. Targets are often set arbitrarily, often...

Data from: Direct and indirect effects of nursery habitats on coral-reef fish assemblages, grazing pressure, and benthic dynamics

Alastair R. Harborne, Ivan Nagelkerken, Nicholas H. Wolff, Yves-Marie Bozec, Martijn Dorenbosch, Monique G. G. Grol & Peter J. Mumby
Migrating species are common within seascapes, but the potential for these movements to alter the populations and functional roles of non-migrating species (e.g. by increasing predation) is rarely investigated. This study considers whether the presence of nursery habitats (mangroves and seagrass) simply enhances the abundance of nursery-using parrotfishes and piscivores on nearby coral reefs, or also affects other parrotfishes. Data from 131 reef sites and multiple seascape configurations across 13 degrees of latitude were used...

Data from: The role of defensive ecological interactions in the evolution of conotoxins

Jutty Rajan Prashanth, Sebastien Dutertre, Ai-Hua Jin, Vincent Lavergne, Brett Hamilton, Fernanda C. Cardoso, John Griffin, Deon J. Venter, Paul F. Alewood, Richard J. Lewis & A. H. Jin
Venoms comprise of complex mixtures of peptides evolved for predation and defensive purposes. Remarkably, some carnivorous cone snails can inject two distinct venoms in response to predatory or defensive stimuli, providing a unique opportunity to study separately how different ecological pressures contribute to toxin diversification. Here, we report the extraordinary defensive strategy of the Rhizoconus subgenus of cone snails. The defensive venom from this worm-hunting subgenus is unusually simple, almost exclusively composed of αD-conotoxins instead...

Data from: Heterogeneity of genetic architecture of body size traits in a free-living population

Camillo Bérénos, Philip A. Ellis, Jill G. Pilkington, S. Hong Lee, Jake Gratten & Josephine M. Pemberton
Knowledge of the underlying genetic architecture of quantitative traits could aid in understanding how they evolve. In wild populations, it is still largely unknown whether complex traits are polygenic or influenced by few loci with major effect, due to often small sample sizes and low resolution of marker panels. Here, we examine the genetic architecture of five adult body size traits in a free-living population of Soay sheep on St Kilda using 37 037 polymorphic...

Data from: Passive restoration of sub-tropical grassland after abandonment of cultivation

Rod J. Fensham, Don W. Butler, Russell J. Fairfax, Amy R. Quintin & John M. Dwyer
Passive restoration of grasslands after the abandonment of cultivation may be a viable restoration option where seed sources from remnant grasslands are available, and if the risk of deflected succession is low. Passive restoration of subtropical grassland in Queensland, Australia was evaluated along a chronosequence of abandoned cultivation (fallow) paddocks. Plant communities in fallow paddocks were compared with nearby remnant grassland. On average, species richness recovers after 60 years of abandonment and floristic composition shows...

Data from: A phylogenetic analysis of egg size, clutch size, spawning mode, adult body size, and latitude in reef fishes

Katja Kasimatis & Cynthia Riginos
Theoretical treatments of egg size in fishes suggest that constraints on reproductive output should create trade-offs between the size and number of eggs produced per spawn. For marine reef fishes, the observation of distinct reproductive care strategies (demersal guarding, egg scattering, and pelagic spawning) has additionally prompted speculation that these strategies reflect alternative fitness optima with selection on egg size differing by reproductive mode and perhaps latitude. Here, we aggregate data from 278 reef fish...

Data from: Dealing with uncertainty in landscape genetic resistance models: a case of three co-occurring marsupials

Rachael Y. Dudaniec, Jessica Worthington-Wilmer, Jeffrey O. Hanson, Matthew Warren, Sarah Bell, Jonathan R. Rhodes & Jessica Worthington Wilmer
Landscape genetics lacks explicit methods for dealing with the uncertainty in landscape resistance estimation, which is particularly problematic when sample sizes of individuals are small. Unless uncertainty can be quantified, valuable but small datasets may be rendered unusable for conservation purposes. We offer a method to quantify uncertainty in landscape resistance estimates using multi-model inference as an improvement over single-model based inference. We illustrate the approach empirically using co-occurring, woodland-preferring Australian marsupials within a common...

Data from: Adapting environmental management to uncertain but inevitable change

Sam C. Nicol, Richard A. Fuller, Takuya Iwamura, Iadine Chades & S. Nicol
Implementation of adaptation actions to protect biodiversity is limited by uncertainty about the future. One reason for this is the fear of making the wrong decisions caused by the myriad future scenarios presented to decision-makers. We propose an adaptive management (AM) method for optimally managing a population under uncertain and changing habitat conditions. Our approach incorporates multiple future scenarios and continually learns the best management strategy from observations, even as conditions change. We demonstrate the...

Data from: Signaling cascades and the importance of moonlight in coral broadcast mass spawning

Paulina Kaniewska, Shahar Alon, Sarit Karako-Lampert, Ove Hoegh-Guldberg & Oren Levy
Many reef-building corals participate in a mass-spawning event that occurs yearly on the Great Barrier Reef. This coral reproductive event is one of earth's most prominent examples of synchronised behavior, and coral reproductive success is vital to the persistence of coral reef ecosystems. Although several environmental cues have been implicated in the timing of mass spawning, the specific sensory cues that function together with endogenous clock mechanisms to ensure accurate timing of gamete release are...

Data from: Termite mounds differ in their importance for herbivores across savanna types, seasons and spatial scales

Andrew B. Davies, Shaun R. Levick, Mark P. Robertson, Berndt J. Van Rensburg, Gregory P. Asner & Catherine L. Parr
Herbivores do not forage uniformly across landscapes, but select for patches of higher nutrition and lower predation risk. Macrotermes mounds contain higher concentrations of soil nutrients and support grasses of higher nutritional value than the surrounding savanna matrix, attracting mammalian grazers that preferentially forage on termite mound vegetation. However, little is known about the spatial extent of such termite influence on grazing patterns and how it might differ in time and space. We measured grazing...

Data from: The cost and feasibility of marine coastal restoration

Elisa Bayraktarov, Megan I. Saunders, Sabah Abdullah, Morena Mills, Jutta Beher, Hugh P. Possingham, Peter J. Mumby & Catherine E. Lovelock
Land-use change in the coastal zone has led to worldwide degradation of marine coastal ecosystems and a loss of the goods and services they provide. Restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed and is critical for habitats where natural recovery is hindered. Uncertainties about restoration cost and feasibility can impede decisions on whether, what, how, where, and how much to restore. Here, we perform...

Data from: High Rates of Asymptomatic, Sub-microscopic Plasmodium vivax Infection and Disappearing Plasmodium falciparum Malaria in an Area of Low Transmission in Solomon Islands

Andreea Waltmann, Andrew W. Darcy, Ivor Harris, Cristian Koepfli, John Lodo, Ventis Vahi, David Piziki, G. Dennis Shanks, Alyssa Barry, Maxine Whittaker, James W. Kazura, Ivo Mueller & Alyssa E. Barry
Introduction: Solomon Islands is intensifying national efforts to achieve malaria elimination. A long history of indoor spraying with residual insecticides, combined recently with distribution of long lasting insecticidal nets and artemether-lumefantrine therapy, has been implemented in Solomon Islands. The impact of these interventions on local endemicity of Plasmodium spp. is unknown. Methods: In 2012, a cross-sectional survey of 3501 residents of all ages was conducted in Ngella, Central Islands Province, Solomon Islands. Prevalence of Plasmodium...
