Data from: Interglacial microrefugia and diversification of a cactus species complex: phylogeography and palaeodistributional reconstructions for Pilosocereus aurisetus and allies

Isabel A. S. Bonatelli, Manolo F. Perez, A. Townsend Peterson, Nigel P. Taylor, Daniela C. Zappi, Marlon C. Machado, Ingrid Koch, Adriana H. C. Pires & Evandro M. Moraes
The role of Pleistocene climate changes in promoting evolutionary diversification in global biota is well documented, but the great majority of data regarding this subject come from North America and Europe, which were greatly affected by glaciation. The effects of Pleistocene changes on cold- and/or dry-adapted species in tropical areas where glaciers were not present remain sparsely investigated. Many such species are restricted to small areas surrounded by unfavourable habitats, which may represent potential interglacial...

Data from: Next-Gen phylogeography of rainforest trees: measuring landscape-level cpDNA variation from whole-genome sequencing.

Marlien Van Der Merwe, Hannah McPherson, Maurizio Rossetto & Juelian Siow
Standardized phylogeographic studies across co-distributed taxa can identify important refugia and biogeographic barriers, and potentially uncover how changes in adaptive constraints through space and time impact on the distribution of genetic diversity. The combination of Next Generation Sequencing and methodologies that enable uncomplicated analysis of the full chloroplast genome may provide an invaluable resource for such studies. Here we assess the potential of a shotgun-based method across twelve non-model rainforest trees sampled from two evolutionary...

Data from: Long-term nitrogen addition causes the evolution of less cooperative mutualists

Dylan Jones Weese, Katy D. Heath, Bryn T. M. Dentinger & Jennifer Ann Lau
Human activities have altered the global nitrogen (N) cycle, and as a result, elevated N inputs are causing profound ecological changes in diverse ecosystems. The evolutionary consequences of this global change have been largely ignored even though elevated N inputs are predicted to cause mutualism breakdown and the evolution of decreased cooperation between resource mutualists. Using a long-term (22 year) N addition experiment, we find that elevated N inputs have altered the legume-rhizobium mutualism (where...

Data from: Management-driven evolution in a domesticated ecosystem

Vigdis Vandvik, Joachim P. Töpper, Zoë Cook, Matthew I. Daws, Einar Heegaard, Inger E. Måren, Liv Guri Velle, I. E. Maren & J. P. Topper
Millennia of human land-use have resulted in the widespread occurrence of what have been coined ‘domesticated ecosystems’. The anthropogenic imprints on diversity, composition, structure and functioning of such systems are well documented. However, evolutionary consequences of human activities in these ecosystems are enigmatic. Calluna vulgaris (L.) is a keystone species of coastal heathlands in northwest Europe, an ancient semi-natural landscape of considerable conservation interest. Like many species from naturally fire-prone ecosystems, Calluna shows smoke-adapted germination,...

Data from: Plant host and soil origin influence fungal and bacterial assemblages in the roots of woody plants

Gregory Bonito, Hannah Reynolds, Brendan P. Hodkinson, Jessica Nelson, Gerald Tuskan, , Christopher W. Schadt, Rytas Vilgalys & Michael S. Robeson
Microbial communities in plant roots provide critical links between above and belowground processes in terrestrial ecosystems. Variation in root communities has been attributed to plant host effects and microbial host preferences, as well as to factors pertaining to soil conditions, microbial biogeography and the presence of viable microbial propagules. To address hypotheses regarding the influence of plant host and soil biogeography on root fungal and bacterial communities we designed a trap-plant bioassay experiment. Replicate Populus,...

Data from: Genomics of the divergence continuum in an African plant biodiversity hotspot, I: drivers of population divergence in Restio capensis (Restionaceae)

Christian Lexer, Rafael O. Wüest, Sofia Mangili, Myriam Heuertz, Kai N. Stolting, Peter B. Pearman, Felix Forest, Nicolas Salamin, Niklaus E. Zimmermann & Eligio Bossolini
Understanding the drivers of population divergence, speciation and species persistence is of great interest to molecular ecology, especially for species-rich radiations inhabiting the world’s biodiversity hotspots. The toolbox of population genomics holds great promise for addressing these key issues, especially if genomic data are analyzed within a spatially and ecologically explicit context. We have studied the earliest stages of the divergence continuum in the Restionaceae, a species-rich and ecologically important plant family of the Cape...
