Data from: No evidence of foliar disease impact on crop root functional strategies and soil microbial communities: What does this mean for organic coffee?

Stephanie Gagliardi, Jacques Avelino, Roberta Fulthorpe, Elias De Melo Virginio Filho & Marney Isaac
Global climate change is increasing pest and pathogen pressures on plant communities, deteriorating optimal plant functioning. In plant communities, root functional trait expression and microbial communities are important indicators of plant functioning belowground, and, when confronted with pathogens aboveground, can simultaneously reflect plant defence strategies. Yet, while research is continuing to emerge on the response of root functional traits and microbial processes to pathogens aboveground, little work has investigated these interactions in tree-crops, or the...

Global flyway evolution in red knots Calidris canutus and genetic evidence for a Nearctic refugium

Jesse Conklin, Yvonne Verkuil, Phil Battley, Chris Hassell, Job Ten Horn, James Johnson, Pavel Tomkovich, Allan Baker, Theunis Piersma & Michaël Fontaine
Present-day ecology and population structure are the legacies of past climate and habitat perturbations, and this is particularly true for species that are widely distributed at high latitudes. The red knot, Calidris canutus, is an arctic-breeding, long-distance migratory shorebird with six recognized subspecies defined by differences in morphology, migration behavior, and annual-cycle phenology, in a global distribution thought to have arisen just since the Last Glacial Maximum (LGM). We used nextRAD sequencing of 10,881 single-nucleotide...

Host traits measurements after evolution with or without parasites during range expansions

Giacomo Zilio
Rapid evolutionary changes during range expansions can lead to the divergence between range core and front populations, with the emergence of dispersal syndromes. Besides intraspecific effects, range expansions may be impacted by interspecific interactions such as parasitism. Yet, despite the potentially large impact of parasites imposing additional selective pressures on the host, their role on range expansions remains largely unexplored. Here, we investigated whether parasites affect the evolution of host dispersal syndromes during spatial spread....

Cross-scale drivers of woody plant species commonness and rarity in the Brazilian drylands

Bruno X. Pinho, Diego Trindade, Carlos Peres, Davi Jamelli, Renato A. F. De Lima, Elâine M.S. Ribeiro, Inara R. Leal & Marcelo Tabarelli
Aim: Locally abundant species are typically widespread, while locally scarce species are geographically restricted – the so-called abundance-occupancy relationships (AORs). AORs help explain the drivers of species rarity and community assembly, but little is known about how variation around such relationships is driven by species traits and niche-based processes, particularly in tropical woody plants. We tested the hypothesis that AORs in tropical dryland woody plants are positive and mediated by niche and functional traits along...

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Rafaella Canessa, Liesbeth Van Den Brink, Monica Berdugo, Stephan Hattenschwiler, Rodrigo Rios, Alfredo Saldana, Katja Tielboerger & Maaike Bader
Litter decomposition is controlled by climate, litter quality and decomposer communities. Because the decomposition of specific litter types is also influenced by the properties of adjacent types, mixing litter types may result in non-additive effects on overall decomposition rates. The strength of these effects seems to depend on the litter functional diversity. However, it is unclear which functional traits or combination of traits explain litter mixture effects and if these depend on the range of...

Data from: Nitrogen availability and plant-plant interactions drive leaf silicon concentration in wheat genotypes

Félix De Tombeur, Taïna Lemoine, Cyrille Violle, Hélène Fréville, Sarah Thorne, Sue Hartley, Hans Lambers & Florian Fort
Estimating plasticity of leaf silicon (Si) in response to abiotic and biotic factors underpins our comprehension of plant defences and stress resistance in natural and agroecosystems. However, how nitrogen (N) addition and intraspecific plant-plant interactions affect Si accumulation remains unclear. We grew 19 durum wheat genotypes (Triticum turgidum ssp. durum) in pots, either alone, or in intra- or intergenotypic cultures of two individuals, and with or without N. Aboveground biomass, plant height and leaf [Si]...

Size-dependent intraspecific variation in wood traits has little impact on aboveground carbon estimates in a tropical forest landscape

Wirong Chanthorn, Patcharapan Thripob, Claire Fortunel, Maxime Réjou-Méchain & Anuttara Nathalang
There is increasing evidence that intraspecific trait variation plays a role in governing rates of ecosystem functioning. While wood traits such as wood specific gravity (WSG) and wood carbon concentration (WCC) are key drivers of forest aboveground carbon (AGC) stocks, the sources of intraspecific variation in these wood traits and the consequences of this variation on AGC are poorly known, especially in the tropics. Here, we investigated intraspecific variation in wood specific gravity (WSG) and...

Environmental variation in sex ratios and sexual dimorphism in three wind-pollinated dioecious plant species

Sarah Bürli, John R. Pannell & Jeanne Tonnabel
Variation in plant sex ratios is often attributable to sex-specific mortality in heterogeneous environments that differentially limit male and female plant reproduction. Yet sexual dimorphism and plastic responses to environmental heterogeneity are common and may co-vary with variation in sex ratios. Here, we show that the sex ratio and the degree of sexual dimorphism for a number of plant traits varied along climatic and elevation gradients in three wind-pollinated dioecious species, Rumex lunaria, Urtica dioica...

Greater functional similarity in mobile compared to sessile assemblages colonizing artificial coastal habitats

Jean-Charles Leclerc, Naily Nashira Figueroa, Antonio Brante & Frédérique Viard
Among anthropogenic habitats built in the marine environment, floating and non-floating structures can be colonized by distinct assemblages. However, there is little knowledge whether these differences are also reflected in the functional structure. This study compared the functional diversity of sessile and mobile invertebrate assemblages that settle over 3 months on floating vs. non-floating artificial habitats, in two Chilean ports. Using morphological, trophic, behavioral, and life history traits, we found differences between mobile and sessile...

Data from: The evolutionary pathways for local adaptation in mountain hares

Iwona Giska, João Pimenta, Liliana Farelo, Pierre Boursot, Klaus Hackländer, Hannes Jenny, Neil Reid, W. Ian Montgomery, Paulo A. Prodöhl, Paulo C. Alves & José Melo-Ferreira
Understanding the evolution of local adaptations is a central aim of evolutionary biology and key for the identification of unique populations and lineages of conservation relevance. By combining RAD sequencing and whole-genome sequencing, we identify genetic signatures of local adaptation in mountain hares (Lepus timidus) from isolated and distinctive habitats of its wide distribution: Ireland, the Alps and Fennoscandia. We recovered full mitochondrial DNA sequences from whole-genome sequencing data and used it to recontruct the...

Data from: Climatic niche lability but growth form conservatism in the African woody flora

Anaïs-Pasiphaé Gorel, Olivier J. Hardy, Gilles Dauby, Kyle G. Dexter, Ricardo A. Segovia, Kathy Steppe & Adeline Fayolle
Climatic niche evolution during the diversification of tropical plants has received little attention in Africa. To address this, we characterized the climatic niche of >4000 tropical African woody species, distinguishing two broad bioclimatic groups (forest vs. savanna) and six subgroups. We quantified niche conservatism versus lability at the genus level and for higher clades, using a molecular phylogeny of >800 genera. Although niche stasis at speciation is prevalent, numerous clades individually cover vast climatic spaces...

Large Herbivore Nemabiomes: Patterns of Diversity and Sharing

Georgia Titcomb, Johan Pansu, Matthew Hutchinson, Kaia Tombak, Christina Hansen, Chris Baker, Tyler Kartzinel, Hillary Young & Robert Pringle
Amidst global shifts in the distribution and abundance of wildlife and livestock, we have only a rudimentary understanding of ungulate parasite communities and parasite-sharing patterns. We used qPCR and DNA metabarcoding of fecal samples to characterize gastrointestinal nematode (Strongylida) community composition and sharing among 17 sympatric species of wild and domestic large mammalian herbivore in central Kenya. We tested a suite of hypothesis-driven predictions about the role of host traits and phylogenetic relatedness in describing...

The global distribution of known and undiscovered ant biodiversity

Jamie Kass, Benoit Guénard, Kenneth Dudley, Clinton Jenkins, Fumika Azuma, Brian Fisher, Catherine Parr, Heloise Gibb, John Longino, Philip Ward, Anne Chao, David Lubertazzi, Michael Weiser, Walter Jetz, Robert Guralnick, Rumsaïs Blatrix, James Des Lauriers, David Donoso, Christos Georgiadis, Kiko Gomez, Peter Hawkes, Robert Johnson, John Lattke, Joe MacGown, William Mackay … & Evan Economo
Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiversity informatics, range modeling, and machine learning to synthesize existing knowledge and predict the distribution of undiscovered diversity. We find that ants and different vertebrate groups have distinct features in their...

Data from: The effect of copy number hemiplasy on gene family evolution

Qiuyi Li, Yao-Ban Chan, Nicolas Galtier & Celine Scornavacca
The evolution of gene families is complex, involving gene-level evolutionary events such as gene duplication, horizontal gene transfer, and gene loss (DTL), and other processes such as incomplete lineage sorting (ILS). Because of this, topological differences often exist between gene trees and species trees. A number of models have been recently developed to explain these discrepancies, the most realistic of which attempt to consider both gene-level events and ILS. When unified in a single model,...

The generality of cryptic dietary niche differences in diverse large-herbivore assemblages

Robert Pringle, Johan Pansu, Matthew Hutchinson, T. Michael Anderson, Mariska Te Beest, Colleen Begg, Keith Begg, Aurelie Bonin, Lackson Chama, Simon Chamaillé-Jammes, Eric Coissac, Joris Cromsigt, Margaret Demmel, Jason Donaldson, Jennifer Guyton, Christina Hansen, Christopher Imakando, Azwad Iqbal, Davis Kalima, Graham Kerley, Samson Kurukura, Marietjie Landman, Ryan Long, Isaack Munuo, Ciara Nutter … & Tyler Kartzinel
Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth-forms but are agnostic towards food-plant species identity. Empirical support for these models is variable, suggesting that additional mechanisms of resource partitioning may be important in sustaining large-herbivore diversity in African savannas. We used DNA metabarcoding to conduct a taxonomically...

Plant community impact on productivity: trait diversity or key(stone) species effects?

Philipp Brun, Cyrille Violle, David Mouillot, Nicolas Mouquet, Brian Enquist, François Munoz, Tamara Munkemuller, Annette Ostling, Niklaus Zimmermann & Wilfried Thuiller
Outside controlled experimental plots, the impact of community attributes on primary productivity has rarely been compared to that of individual species. Here, we identified plant species of high importance for productivity (key species) in >29,000 diverse grassland communities in the European Alps, and compared their effects with those of community-level measures of functional composition (weighted means, variances, skewness, and kurtosis). After accounting for the environment, the five most important key species jointly explained more deviance...

Does colour impact responses to images in geckos?

Ylenia Chiari, Nathan Katlein, Miranda Ray, Anna Wilkinson, Julien Claude, Maria Kiskowski, Bin Wang & Scott Glaberman
Animals are exposed to different visual stimuli that influence how they perceive and interact with their environment. Visual information such as shape and colour can help the animal detect, discriminate and make appropriate behavioural decisions for mate selection, communication, camouflage, and foraging. In all major vertebrate groups, it has been shown that certain species can discriminate and prefer certain colours and that colours may increase the response to a stimulus. However, since colour is often...

Taxonomy based on limited genomic markers may underestimates species diversity of rockhopper penguins and threaten their conservation

María José Frugone, Theresa Cole, María Eugenia López, Gemma Clucas, Pável Matos-Maraví, Nicolás Lois, Pierre Pistorius, Francesco Bonadonna, Phil Trathan, Andrea Polanowski, Barbara Wienecke, Andrea Raya-Rey, Klemens Pütz, Antje Steinfurth, Ke Bi, Cynthia Wang-Claypool, Rauri C. K. Bowie, Jonathan Waters, Elie Poulin & Juliana Vianna
Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures and evolutionary histories. Reliance on limited numbers of genetic markers that may be underpowered can make species delimitation even more challenging, potentially resulting in taxonomic inconsistencies. Rockhopper penguins of the genus Eudyptes comprise three broadly recognized taxa: northern (E. moseleyi), southern (E. chrysocome), and eastern rockhopper (E....

Joint analysis of microsatellites and flanking sequences enlightens complex demographic history of interspecific gene flow and vicariance in rear-edge oak populations

Olivier Lepais, Abdeldjalil Aissi, Errol Véla & Yassine Beghami
Inference of recent population divergence requires fast evolving markers and necessitates to differentiate shared genetic variation caused by ancestral polymorphism and gene flow. Theoretical research shows that the use of compound marker systems integrating linked polymorphisms with different mutational dynamics, such as a microsatellite and its flanking sequences, can improve estimation of population structure and inference of demographic history, especially in the case of complex population dynamics. However, empirical application in natural populations has so...
