Data from: Maternal-by-environment but not genotype-by-environment interactions in a fish without parental care

Regina Vega-Trejo, Megan L. Head, Michael D. Jennions & Loeske E.B. Kruuk
The impact of environmental conditions on the expression of genetic variance and on maternal effects variance remains an important question in evolutionary quantitative genetics. We investigate here the effects of early environment on variation in seven adult life history, morphological, and secondary sexual traits (including sperm characteristics) in a viviparous poeciliid fish, the mosquitofish Gambusia holbrooki. Specifically, we manipulated food availability during early development and then assessed additive genetic and maternal effects contributions to the...

Data from: Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests

Renato Crouzeilles, Mariana S. Ferreira, Robin L. Chazdon, David B. Lindenmayer, Jerônimo B. B. Sansevero, Lara Monteiro, Alvaro Iribarrem, Agnieszka E. Latawiec & Bernardo B. N. Strassburg
Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests? Our meta-analysis of 133 studies demonstrated that natural regeneration surpasses active restoration in achieving tropical forest restoration success for all three biodiversity groups (plants, birds, and invertebrates) and five measures of vegetation structure (cover, density, litter, biomass, and height) tested. Restoration success for biodiversity and vegetation...

Data from: When can refuges mediate the genetic effects of fire regimes? A simulation study of the effects of topography and weather on neutral and adaptive genetic diversity in fire-prone landscapes

Sam C. Banks, Ian D. Davies & Geoffrey J. Cary
Understanding how landscape heterogeneity mediates the effects of fire on biodiversity is increasingly important under global changes in fire regimes. We used a simulation experiment to investigate how fire regimes interact with topography and weather to shape neutral and selection-driven genetic diversity under alternative dispersal scenarios, and to explore the conditions under which microrefuges can maintain genetic diversity of populations exposed to recurrent fire. Spatial heterogeneity in simulated fire frequency occurred in topographically complex landscapes,...

Plant Respiration Modelling with JULES for a changing climate (1860-2100)

C. Huntingford, O.K. Atkin, A. Martinez-De La Torre, L.M. Mercado, M.A. Heskel, A.B. Harper, K.J. Bloomfield, O.S. O'Sullivan, P.B. Reich, K.R. Wythers, E.E. Butler, M. Chen, K.L. Griffin, P. Meir, M.G. Tjoelker, M.H. Turnbull, S. Sitch, A. Wiltshire & Y. Malhi
The dataset contains annual global plant respiration (and related diagnostics, such as Net Primary Productivity, Gross Primary Productivity and soil respiration), applicable for pre-industrial times (taken as year 1860) through to the end of the 21st Century (year 2100). The spatial resolution of the data is 2.5 degrees latitude x 3.75 degrees longitude. These diagnostics are outputs from the Joint UK Land Environment Simulator (JULES land surface model) under four different approaches to calcluate leaf...

Data from: Adult frogs and tadpoles have different macroevolutionary patterns across the Australian continent

Emma Sherratt, Marta Vidal-Garcia, Marion Anstis & J. Scott Keogh
Developmental changes through an animal’s life are generally understood to contribute to the resulting adult morphology. A possible exception are species with complex life cycles, where individuals pass through distinct ecological and morphological life stages during their ontogeny, ending with metamorphosis to the adult form. Antagonistic selection is expected to drive low genetic correlations between life stages, theoretically permitting stages to evolve independently. Using the Australian frog radiation, we examine the evolutionary consequences on morphological...

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: Secondary compounds from exotic tree plantations change female mating preferences in the palmate newt (Lissotriton helveticus)

Maider Iglesias-Carrasco, Megan L. Head, Michael D. Jennions & Carlos Cabido
Selection can favor phenotypic plasticity in mate choice in response to environmental factors that alter the costs and benefits of being choosy, or of choosing specific mates. Human-induced environmental change could alter sexual selection by affecting the costs of mate choice, or by impairing the ability of individuals to identify preferred mates. For example, variation in mate choice could be driven by environmentally induced differences in body condition (e.g. health) that change the cost of...

Data from: Isolation by distance and isolation by environment contribute to population differentiation in Protea repens (Proteaceae L.), a widespread South African species

Rachel Prunier, Melis Akman, Colin T. Kremer, Nicola C. Aitken, Aaron Chuah, Justin Borevitz, Kent E. Holsinger & Nicola Aitken
PREMISE OF THE STUDY: The Cape Floristic Region (CFR) of South Africa is renowned for its botanical diversity, but the evolutionary origins of this diversity remain controversial. Both neutral and adaptive processes have been implicated in driving diversification, but population-level studies of plants in the CFR are rare. Here, we investigate the limits to gene flow and potential environmental drivers of selection in Protea repens L. (Proteaceae L.), a widespread CFR species. METHODS: We sampled...

Data from: Morphological and genetic evidence for a new karst specialist lizard from New Guinea (Cyrtodactylus: Gekkonidae).

Stuart V. Nielsen & Paul M. Oliver
Exposed limestone karst landscapes, especially in the tropics, are often home to distinctive and specialised biotas. Amongst vertebrates, a particularly large number of karst-associated lizard taxa have been described, but for the vast majority, evidence of specific adaptions to karst is lacking. A number of studies, however, have provided evidence of consistent morphological trends in lizards that utilise complex, three-dimensional, saxicoline habitats such as those that typify karst areas. Here we combine morphological and genetic...

Data from: No phenotypic plasticity in nest-site selection in response to extreme flooding events

Liam D. Bailey, Bruno Ens, Christiaan Both, Dik Heg, Kees Oosterbeek & Martijn Van De Pol
Phenotypic plasticity is a crucial mechanism for responding to changes in climatic means, yet we know little about its role in responding to extreme climatic events (ECEs). ECEs may lack the reliable cues necessary for phenotypic plasticity to evolve; however, this has not been empirically tested. We investigated whether behavioural plasticity in nest-site selection allows a long-lived shorebird (Haematopus ostralegus) to respond to flooding. We collected longitudinal nest elevation data on individuals over two decades,...

Data from: Plant traits of propagule banks and standing vegetation reveal flooding alleviates impacts of agriculture on wetland restoration

Samantha K. Dawson, David I. Warton, Richard T. Kingsford, Peter Berney, David A. Keith & Jane A. Catford
1. Restoration of degraded plant communities requires understanding of community assembly processes. Human land use can influence plant community assembly by altering environmental conditions and species’ dispersal patterns. Flooding, including from environmental flows, may counteract land use effects on wetland vegetation. We examined the influence of land use history and flood frequency on the functional composition of wetland plant communities along a regulated river. 2. We applied fourth corner modelling to determine species’ trait-based responses...

Data from: Evolution of extreme ontogenetic allometric diversity and heterochrony in pythons, a clade of giant and dwarf snakes

Damien Esquerre, Emma Sherratt & J. Scott Keogh
Ontogenetic allometry, how species change with size through their lives, and heterochony, a decoupling between shape, size and age, are major contributors to biological diversity. However, macro-evolutionary allometric and heterochronic trends remain poorly understood because previous studies have focused on small groups of closely related species. Here we focus on testing hypotheses about the evolution of allometry and how allometry and heterochrony drive morphological diversification at the level of an entire species-rich and diverse clade....

Data from: Analysis of phylogenomic tree space resolves relationships among marsupial families

David A. Duchêne, Jason G. Bragg, Sebastian Duchêne, Linda E. Neaves, Sally Potter, Craig Moritz, Rebecca N. Johnson, Simon Y. W. Ho & Mark D. B. Eldridge
A fundamental challenge in resolving evolutionary relationships across the Tree of Life is to account for heterogeneity in the evolutionary signal across loci. Studies of marsupial mammals have demonstrated that this heterogeneity can be substantial, leaving considerable uncertainty in the evolutionary timescale and relationships within the group. Using simulations and a new phylogenomic data set comprising nucleotide sequences of 1550 loci from 18 of the 22 extant marsupial families, we demonstrate the power of a...

Data from: Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species

Blake V. Dickson, Emma Sherratt, Jonathan B. Losos & Stephanie E. Pierce
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground. Members of each ecomorph category possess a specific set of morphological, ecological and behavioural characteristics which have been acquired convergently. Here we test whether the semicircular canal system—the organ of balance during movement—is also convergent among ecomorphs, reflecting the shared sensory requirements...

Data from: Detecting rare asymmetrically methylated cytosines and decoding methylation patterns in the honeybee genome

Laura Welsh, Ryszard Maleszka & Sylvain Foret
Context-dependent gene expression in eukaryotes is controlled by several mechanisms including cytosine methylation that primarily occurs in the CG dinucleotides (CpGs). However, less frequent non-CpG asymmetric methylation has been found in various cell types, such as mammalian neurons, and recent results suggest that these sites can repress transcription independently of CpG contexts. In addition, an emerging view is that CpG hemimethylation may arise not only from deregulation of cellular processes but also be a standard...

Data from: Invasive cane toads are unique in shape but overlap in ecological niche compared to Australian native frogs

Marta Vidal Garcia, J. Scott Keogh & Marta Vidal-García
Invasive species are an important issue worldwide but predicting invasiveness, and the underlying mechanisms that cause it, is difficult. There are several primary hypotheses to explain invasion success. Two main hypothesis based on niche spaces stand out as alternative, although not exclusive. The empty niche hypothesis states that invaders occupy a vacant niche space in the recipient community, and the niche competition hypothesis states that invaders overlap with native species in niche space. Studies on...

Data from: Evolutionary relationships among pollinators and repeated pollinator sharing in sexually deceptive orchids

Ryan D. Phillips, Graham R. Brown, Kingsley W. Dixon, Christine Hayes, Celeste C. Linde & Rod Peakall
The mechanism of pollinator attraction is predicted to strongly influence both plant diversification and the extent of pollinator sharing between species. Sexually deceptive orchids rely on mimicry of species-specific sex pheromones to attract their insect pollinators. Given that sex pheromones tend to be conserved among related species, we predicted that in sexually deceptive orchids, (i) pollinator sharing is rare, (ii) closely related orchids use closely related pollinators and (iii) there is strong bias in the...

Data from: Egg mimicry by the pacific koel: mimicry of one host facilitates exploitation of other hosts with similar egg types

Virginia E. Abernathy, Jolyon Troscianko & Naomi E. Langmore
When brood parasites exploit multiple host species, egg rejection by hosts may select for the evolution of host-specific races, where each race mimics a particular host’s egg type. However, some brood parasites that exploit multiple hosts with the ability to reject foreign eggs appear to have only a single egg type. In these cases, it is unclear how the parasite egg escapes detection by its hosts. Three possible explanations are: (i) host-specific races are present,...

Data from: Phylogenetically informed spatial planning is required to conserve the mammalian tree of life

Dan F. Rosauer, Laura J. Pollock, Simon Linke & Walter Jetz
In the face of the current extinction crisis and severely limited conservation resources, safeguarding the tree of life is increasingly recognized as a high priority. We conducted a first systematic global assessment of the conservation of phylogenetic diversity (PD) that uses realistic area targets and highlights the key areas for conservation of the mammalian tree of life. Our approach offers a substantially more effective conservation solution than one focused on species. In many locations, priorities...

Data from: Mass turnover and recovery dynamics of a diverse Australian continental radiation

Ian G. Brennan & Paul M. Oliver
Trends in global and local climate history have been linked to observed macroevolutionary patterns across a variety of organisms. These climatic pressures may unilaterally or asymmetrically influence the evolutionary trajectory of clades. To test and compare signatures of changing global (Eocene-Oligocene boundary cooling) and continental (Miocene aridification) environments on a continental fauna, we investigated the macroevolutionary dynamics of one of Australia's most diverse endemic radiations, pygopodoid geckos. We generated a time-calibrated phylogeny (>90% taxon coverage)...

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: Territorial battles between fiddler crab species

Huon L. Clark & Patricia R. Y. Backwell
Many species worldwide are impacted by habitat loss. This may result in increased competition both within species and between species. Many studies have demonstrated that when two previously non-overlapping species are forced to compete over a resource, one species is likely to become dominant over the other. This study explores the impact a larger species of fiddler crab (Tabuca elegans—previously known as Uca elegans) has when invading an area previously used solely by a smaller...

Data from: Evaluating multilocus Bayesian species delimitation for discovery of cryptic mycorrhizal diversity

Michael R. Whitehead, Renee A. Catullo, Monica Ruibal, Kingsley W. Dixon, Rod Peakall & Celeste C. Linde
The increasing availability of DNA sequence data enables exciting new opportunities for fungal ecology. However, it amplifies the challenge of how to objectively classify the diversity of fungal sequences into meaningful units, often in the absence of morphological characters. Here, we test the utility of modern multilocus Bayesian coalescent-based methods for delimiting cryptic fungal diversity in the orchid mycorrhiza morphospecies Serendipita vermifera. We obtained 147 fungal isolates from Caladenia, a speciose clade of Australian orchids...

Data from: Chromosomal speciation in the genomics era: disentangling phylogenetic evolution of rock-wallabies

Sally Potter, Jason G. Bragg, Mozes P. Blom, Janine E. Deakin, Mark Kirkpatrick, Mark D. Eldridge, Craig Moritz, Mozes P. K. Blom & Mark D. B. Eldridge
The association of chromosome rearrangements with speciation is well established, and there is a long history of theory and evidence relating to “chromosomal speciation”. Genomic sequencing has the potential to provide new insights into how reorganization of genome structure promotes divergence, and in model systems has demonstrated reduced gene flow in rearranged segments. However, there are limits to what we can understand from a small number of model systems, which each only tell us about...

Data from: Precipitation drives global variation in natural selection

Adam Siepielski, Michael B. Morrissey, Mathieu Buoro, Stephanie M. Carlson, Christina M. Caruso, Sonya M. Clegg, Tim Coulson, Joseph DiBattista, Kiyoko M. Gotanda, Clinton D. Francis, Joe Hereford, Joel G. Kingsolver, Kate E. Augustine, Loeske E. B. Kruuk, Ryan A. Martin, Ben C. Sheldon, Nina Sletvold, Erik I. Svensson, Michael J. Wade & Andrew D. C. MacColl
Climate change has the potential to affect the ecology and evolution of every species on Earth. Although the ecological consequences of climate change are increasingly well documented, the effects of climate on the key evolutionary process driving adaptation—natural selection—are largely unknown. We report that aspects of precipitation and potential evapotranspiration, along with the North Atlantic Oscillation, predicted variation in selection across plant and animal populations throughout many terrestrial biomes, whereas temperature explained little variation. By...
