Oak-associated biodiversity in the UK (OakEcol)

R.J. Mitchell, P.E. Bellamy, C.J. Ellis, R.L. Hewison, N.G. Hodgetts, G.R. Iason, N.A. Littlewood, S. Newey, J.A. Stockan & A.F.S. Taylor
This dataset contains a list of all known birds, bryophytes, fungi, invertebrates, lichens and mammals that use oak (Quercus petraea and Quercus robur) in the UK. In total 2300 species are listed in the dataset. For each species we provide a level of association with oak, ranging from obligate (only found on oak) to cosmopolitan (found on a wide range of other tree species). Data on the ecology of each oak associated species is provided:...

Data from: Hybridisation in closely related Rhododendron species: half of all species differentiating markers experience serious transmission ratio distortion

Tobias Marczewski, David F. Chamberlain & Richard I. Milne
An increasing number of studies of hybridization in recent years have revealed that complete reproductive isolation between species is frequently not finalized in more or less closely related organisms. Most of these species do, however, seem to retain their phenotypical characteristics despite the implication of gene flow, highlighting the remaining gap in our knowledge of how much of an organism's genome is permeable to gene flow, and which factors promote or prevent hybridization. We used...

Data from: Tracking of host defenses and phylogeny during the radiation of Neotropical Inga-Feeding sawflies (Hymenoptera; Argidae)

María-José Endara, James A. Nicholls, Phyllis D. Coley, Dale L. Forrister, Gordon C. Younkin, Kyle G. Dexter, Catherine A. Kidner, R. Toby Pennington, Graham N. Stone, Thomas A. Kursar & R. T. Pennington
Coevolutionary theory has long predicted that the arms race between plants and herbivores is a major driver of host selection and diversification. At a local scale, plant defenses contribute significantly to the structure of herbivore assemblages and the high alpha diversity of plants in tropical rain forests. However, the general importance of plant defenses in host associations and divergence at regional scales remains unclear. Here, we examine the role of plant defensive traits and phylogeny...

Data from: Both temperature fluctuations and East Asian monsoons have driven plant diversification in the karst ecosystems from southern China

Fabien L. Condamine, A.J. Harris, Junlin Chen, Bo Pan, Michael Moeller, Van Sam Hoang, Ming Kang, Hanghui Kong & AJ Harris
Karst ecosystems in southern China are species-rich and have high levels of endemism, yet little is known regarding the evolutionary processes responsible for the origin and diversification of karst biodiversity. The genus Primulina (Gesneriaceae) comprises ca. 170 species endemic to southern China with high levels of ecological (edaphic) specialization, providing an exceptional model to study the plant diversification in karsts. We used molecular data from nine chloroplast and 11 nuclear regions and macroevolutionary analyses to...

Data from: Climate-woodland effects on population genetics for two congeneric lichens with contrasting reproductive strategies

Rocío Belinchón, Christopher J. Ellis, Rebecca Yahr & Christopher J Ellis
Genetic variation is expected to be influenced by the interaction between reproductive mode and dispersal traits on the one hand, and environmental and habitat setting affecting establishment success on the other. We evaluated how environmental/habitat setting affect population genetic variation (i.e. variation in genetic diversity and structure) when regulated by contrasting dispersal traits. We used fungus-specific microsatellite markers to examine genetic diversity and structure of two closely related epiphytic lichen fungi that differ in their...

Data from: RADseq dataset with 90% missing data fully resolves recent radiation of Petalidium (Acanthaceae) in the ultra-arid deserts of Namibia

Erin A. Tripp, Yi-Hsin Erica Tsai, Yongbin Zhuang & Kyle G. Dexter
Deserts, even those at tropical latitudes, often have strikingly low levels of plant diversity, particularly within genera. One remarkable exception to this pattern is the genus Petalidium (Acanthaceae), in which 37 of 40 named species occupy one of the driest environments on Earth, the Namib Desert of Namibia and neighboring Angola. To contribute to understanding this enigmatic diversity, we generated RADseq data for 47 accessions of Petalidium representing 22 species. We explored the impacts of...

Data from: Combined observational and experimental data provide limited support for facilitation in lichens

Måns Svensson, Alexandro Caruso, Rebecca Yahr, Christopher Ellis, Göran Thor & Tord Snäll
It is increasingly recognized that facilitative interactions can shape communities. One of the mechanisms through which facilitation may operate is when one species facilitates the colonization of another through the exchange of shared symbionts. Lichens are symbiotic associations composed of a mycobiont (lichenised-fungus) and one or two photobionts (algae or cyanobacteria). Different lichen species may have overlapping specificity for photobionts, creating the possibility that facilitation drives lichen community assembly. To investigate whether facilitation occurs in...

Data from: Bayesian estimation of the global biogeographical history of the Solanaceae

Julia Dupin, Nicholas J. Matzke, Tiina Särkinen, Sandra Knapp, Richard G. Olmstead, Lynn Bohs & Stacey D. Smith
Aim: The tomato family Solanaceae is distributed on all major continents except Antarctica and has its centre of diversity in South America. Its worldwide distribution suggests multiple long-distance dispersals within and between the New and Old Worlds. Here, we apply maximum likelihood (ML) methods and newly developed biogeographical stochastic mapping (BSM) to infer the ancestral range of the family and to estimate the frequency of dispersal and vicariance events resulting in its present-day distribution. Location:...

Data from: Maintenance of species boundaries in a Neotropical radiation of Begonia

Alex D. Twyford, Catherine A. Kidner & Richard A. Ennos
A major goal of evolutionary biology is to determine the mechanisms generating biodiversity. In Begonia, one of the largest plant genera (1900+ species), it has been postulated that the high number of endemic species is a by-product of low gene flow among populations, which predisposes the group to speciation. However, this model of divergence requires that reproductive barriers accumulate rapidly among diverging species that overlap in their geographic ranges, otherwise speciation will be opposed by...

Data from: Indications for three independent domestication events for the tea plant (Camellia sinensis (L.) O. Kuntze) and new insights into the origin of tea germplasm in China and India revealed by nuclear microsatellites

M. K. Meegahakumbura, M. Wambulwa, K. K. Thapa, M.M. Li, M. Möller, J.C. Xu, J.B. Yang, B.Y. Liu, S. Ranjitkar, J. Liu, D.Z. Li, L.M. Gao, M. C. Wambulwa, M. M. Li, D. Z. Li, L. M. Gao, J. B. Yang & J. C. Xu
Background: Tea is the world’s most popular non-alcoholic beverage. China and India are known to be the largest tea producing countries and recognized as the centers for the domestication of the tea plant (Camellia sinensis (L.) O. Kuntze). However, molecular studies on the origin, domestication and relationships of the main teas, China type, Assam type and Cambod type are lacking. Methodology/Principal Findings: Twenty-three nuclear microsatellite markers were used to investigate the genetic diversity, relatedness, and...

Data from: Convergent morphology in Alpinieae (Zingiberaceae): recircumscribing Amomum as a monophyletic genus

Hugo De Boer, Mark Newman, Axel D. Poulsen, A. Jane Droop, Tomas Fer, Le Thi Thu Hien, Kristyna Hlavata, Vichith Lamxay, James E. Richardson, Karin Steffen, Jana Leong-Škorničková & Axel Dalberg Poulsen
The tropical ginger genus Amomum (Zingiberaceae) has always posed challenges for classification based on morphological characters. Previous molecular phylogenetic studies showed Amomum to be paraphyletic but limited sampling and absence of the data of the type Amomum subulatum made it impossible to resolve the paraphyly and make nomenclatural changes. Here, Amomum is further investigated in a multi-marker phylogenetic framework using matK and nrITS including multiple accessions of the type, the genus Elettaria and additional accessions...

Data from: Graphs in phylogenetic comparative analysis: Anscombe’s quartet revisited

Liam J. Revell, Klaus Schliep, Eugenio Valderrama & James E. Richardson
1. In 1973 the statistician Francis Anscombe used a clever set of bivariate datasets (now known as Anscombe’s quartet) to illustrate the importance of graphing data as a component of statistical analyses. In his example, each of the four datasets yielded identical regression coefficients and model fits, and yet when visualized revealed strikingly different patterns of covariation between x and y. 2. Phylogenetic comparative methods are statistical methods too, yet visualizing the data and phylogeny...

Data from: Genotypic variation in a foundation tree (Populus tremula L.) explains community structure of associated epiphytes

Chantel Davies, Christopher J. Ellis, Glenn R. Iason, Richard A. Ennos, C. Davies, R. A. Ennos, G. R. Iason & C. J. Ellis
Community genetics hypothesizes that within a foundation species the genotype of an individual significantly influences the assemblage of dependent organisms. To assess whether these intra-specific genetic effects are ecologically important, it is required to compare their impact on dependent organisms with that attributable to environmental variation experienced over relevant spatial scales. We assessed bark epiphytes on 27 aspen (Populus tremula L.) genotypes grown in a randomized experimental array at two contrasting sites spanning the environmental...

Data from: Insights into the genetic relationships and breeding patterns of the African tea germplasm based on nSSR markers and cpDNA sequences

Moses C. Wambulwa, Muditha K. Meegahakumbura, Samson Kamunya, Alice Muchugi, Michael Moller, Jie Liu, Jian-Chu Xu, Sailesh Ranjitkar, De-Zhu Li & Lian-Ming Gao
Africa is one of the key centers of global tea production. Understanding the genetic diversity and relationships of cultivars of African tea is important for future targeted breeding efforts for new crop cultivars, specialty tea processing, and to guide germplasm conservation efforts. Despite the economic importance of tea in Africa, no research work has been done so far on its genetic diversity at a continental scale. Twenty-three nSSRs and three plastid DNA regions were used...

Data from: Tiny niches and translocations: the challenge of identifying suitable recipient sites for small and immobile species

Rob W. Brooker, Mark J. Brewer, Andrea J. Britton, Antonia Eastwood, Christopher Ellis, Alessandro Gimona, Laura Poggio & David R. Genney
Assisted colonisation, one form of species translocation, has been proposed as a tool for helping species to track suitable conditions in a changing climate. There are considerable practical challenges associated with it, including predicting where to place translocated individuals. This problem may be particularly big for small and immobile species, where small-scale micro-environmental conditions de-couple them from environmental conditions as projected in large-scale climate models. To investigate this problem we developed a survey-based model to...

Data from: Patterns of mating and generation of diversity in a Geum hybrid swarm

Markus Ruhsam, Peter M. Hollingsworth & Richard A. Ennos
To understand the evolutionary consequences of hybridization between the outcrossing plant Geum rivale and the selfer G. urbanum we tested the predictions of two simple models which assume either A). low or B). high pollen fitness in hybrids. Model A predicts only four genotypic classes (G. rivale, G. rivale backcross (BCR), F1 and G. urbanum) and asymmetric introgression from inbreeding to outbreeding species. Model B predicts additional genotypic classes and potential generation of novel inbreeding...

Data from: Low genetic diversity in small leading edge populations of a European paleoendemic Ramonda serbica (Gesneriaceae) in Bulgaria

Galya Petrova, Stefan Petrov & Michael Möller
Ramonda serbica Panč. (Gesneriaceae) is an endangered endemic species of the Balkan Peninsula. It has been the subject of several studies in the past, but has not yet been investigated in terms of its genetic variation. Here, an Inter Simple Sequence Repeat (ISSR) analysis was performed to determine the genetic diversity of five populations sampled from the geographically eastern fringe of its range in northwestern Bulgaria. We found low levels of genetic diversity and significant...

Data from: Evolution of angiosperm pollen. 6. the Celastrales, Oxalidales, and Malpighiales (COM) clade and Zygophyllales

Zhi-Bin Tao, Alexandra H. Wortley, Lu Lu, De-Zhu Li, Hong Wang & Stephen Blackmore
Analyzing pollen morphological data on a contemporary phylogenetic framework can enhance our understanding of the distribution, diversity, and evolution of palynological characters. In this paper, the sixth in a series detailing pollen morphological characters across angiosperms, we focus on the Celastrales, Oxalidales, and Malpighiales (COM) clade and Zygophyllales, together comprising ca. 20,000 species in 47 families within fabids. We first examined pollen grains from 21 species with light, scanning electron, and transmission electron microscopy, to...

Carl J. Rothfels, Fay-Wei Li, Erin M. Sigel, Layne Huiet, Anders Larsson, Dylan O. Burge, Markus Ruhsam, Michael Deyholos, Douglas E. Soltis, Stewart Jr., C. Neal, Shane W. Shaw, Lisa Pokorny, Tao Chen, Claude DePamphilis, Lisa DeGironimo, Li Chen, Xiaofeng Wei, Xiao Sun, Petra Korall, Dennis W. Stevenson, Sean W. Graham, Gane Ka-Shu Wong, Kathleen M. Pryer, C. Neal Stewart, Gane K-S. Wong … & Claude De Pamphilis
Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, however, to date, these studies have relied almost exclusively on plastid data. Methods: Here we take a curated phylogenomics approach to infer the...
