Data from: Five major shifts of diversification through the long evolutionary history of Magnoliidae (angiosperms)

Julien Massoni, Thomas L. P. Couvreur & Hervé Sauquet
With 10,000 species, Magnoliidae are the largest clade of flowering plants outside monocots and eudicots. Despite an ancient and rich fossil history, the tempo and mode of diversification of Magnoliidae remain poorly known. Using a molecular data set of 12 markers and 220 species (representing >75% of genera in Magnoliidae) and six robust, internal fossil age constraints, we estimate divergence times and significant shifts of diversification across the clade. In addition, we test the sensitivity...

Data from: Asexual queen succession in the higher termite Embiratermes neotenicus

Romain Fougeyrollas, Klára Dolejšová, David Sillam-Dussès, Virginie Roy, Chantal Poteaux, Robert Hanus & Yves Roisin
Asexual queen succession (AQS), in which workers, soldiers and dispersing reproductives are produced sexually while numerous non-dispersing queens arise through thelytokous parthenogenesis, has recently been described in three species of lower termites of the genus Reticulitermes. Here, we show that AQS is not an oddity restricted to a single genus of lower termites, but a more widespread strategy occurring also in the most advanced termite group, the higher termites (Termitidae). We analysed the genetic structure...

Data from: Intra-individual polymorphism in chloroplasts from NGS data: where does it come from and how to handle it?

Next generation sequencing allows access to a large quantity of genomic data. In plants, several studies used whole chloroplast genome sequences for inferring phylogeography or phylogeny. Even though the chloroplast is a haploid organelle, NGS plastome data identified a non negligible number of intra-individual polymorphic SNPs. Such observations could have several causes such as sequencing errors, the presence of heteroplasmy or transfer of chloroplast sequences in the nuclear and mitochondrial genomes. The occurrence of allelic...

Data from: Predictive modelling of habitat selection by marine predators with respect to the abundance and depth distribution of pelagic prey

Charlotte Boyd, Ramiro Castillo, , André E. Punt, Glenn R. VanBlaricom, Henri Weimerskirch, Sophie Bertrand & George L. Hunt
1. Understanding the ecological processes that underpin species distribution patterns is a fundamental goal in spatial ecology. However, developing predictive models of habitat use is challenging for species that forage in marine environments, as both predators and prey are often highly mobile and difficult to monitor. Consequently, few studies have developed resource selection functions for marine predators based directly on the abundance and distribution of their prey. 2. We analysed contemporaneous data on the diving...
