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...

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: 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...

DeWalt, Juan Manuel Dupuy, Sandra M. Durán, Mário Marcos Do Espírito Santo, G. Wilson Fernandes, Yule Roberta Ferreira Nunes … & Jennifer S. Powers
The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen (N)-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest-inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area...

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

Hugo De Boer, Mark Newman, Axel Dalberg Poulsen, A. Jane Droop, Tomas Fer, Le Thi Thu Hien, Kristyna Hlavata, Vichith Lamxay, James E. Richardson, Karin Steffen & Jana Leong-Škorničková
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: Climate-woodland effects on population genetics for two congeneric lichens with contrasting reproductive strategies

Rocío Belinchón, Christopher J. Ellis & Rebecca Yahr
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...
