Comparative transcriptomics of the venoms of continental and insular radiations of West African cones

Samuel Abalde, Manuel J. Tenorio, Carlos M. L. Afonso & Rafael Zardoya
The transcriptomes of the venom glands of 13 closely related species of vermivorous cones endemic to West Africa from genera Africonus and Varioconus were sequenced and venom repertoires compared within a phylogenetic framework. The total number of conotoxin precursors per species varied between 108 and 221. Individuals of the same species shared about one fourth of the total conotoxin precursors. The number of common sequences was drastically reduced in the pairwise comparisons between closely related...

Data from: A congruent phylogenomic signal places eukaryotes within the Archaea.

Tom A. Williams, Peter G. Foster, Tom M. W. Nye, Cymon J. Cox & T. Martin Embley
Determining the relationships among the major groups of cellular life is important for understanding the evolution of biological diversity, but is difficult given the enormous time spans involved. In the textbook 'three domains' tree based on informational genes, eukaryotes and Archaea share a common ancestor to the exclusion of Bacteria. However, some phylogenetic analyses of the same data have placed eukaryotes within the Archaea, as the nearest relatives of different archaeal lineages. We compared the...

Phylogenetic data for the description eight new Halophytophthora species and an updated phylogeny for the genus

Marília Horta Jung, Cristiana Maia, Giusepe Carella, Ivan Milenković, Josef Janoušek, Michal Tomšovský, Saveria Mosca, Leonardo Schena, Alfredo Cravador, Salvatore Moricca & Thomas Jung
During an oomycete survey in December 2015 ten previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described Halophytophthora species, the ten new Halophytophthora taxa from Portugal and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny...

Data from: Form–function relationships in a marine foundation species depend on scale: a shoot to global perspective from a distributed ecological experiment

Jennifer L. Ruesink, John J. Stachowicz, Pamela L. Reynolds, Christoffer Boström, Mathieu Cusson, James Douglass, Johan Eklöf, Aschwin H. Engelen, Masakazu Hori, Kevin Hovel, Katrin Iken, Per-Olav Moksnes, Masahiro Nakaoka, Mary I. O'Connor, Jeanine L. Olsen, Erik E. Sotka, Matthew A. Whalen & Emmett J. Duffy
Form-function relationships in plants underlie their ecosystem roles in supporting higher trophic levels through primary production, detrital pathways, and habitat provision. For widespread, phenotypically-variable plants, productivity may differ not only across abiotic conditions, but also from distinct morphological or demographic traits. A single foundation species, eelgrass (Zostera marina), typically dominates north temperate seagrass meadows, which we studied across 14 sites spanning 32-61° N latitude and two ocean basins. Body size varied by nearly two orders...

Data from: The effects of inbreeding, genetic dissimilarity and phenotype on male reproductive success in a dioecious plant

Frédéric Austerlitz, Gabriela Gleiser, Sara Teixeira & Giorgina Bernasconi
Pollen fate can strongly affect the genetic structure of populations with restricted gene flow and significant inbreeding risk. We established an experimental population of inbred and outbred Silene latifolia plants to evaluate the effects of (i) inbreeding depression, (ii) phenotypic variation and (iii) relatedness between mates on male fitness under natural pollination. Paternity analysis revealed that outbred males sired significantly more offspring than inbred males. Independently of the effects of inbreeding, male fitness depended on...

Data from: Looking into the black box: simulating the role of self-fertilization and mortality in the genetic structure of Macrocystis pyrifera

Mattias L. Johansson, Peter T. Raimondi, Daniel C. Reed, Nelson C. Coelho, Ester A. Serrão & Filipe A. Alberto
Patterns of spatial genetic structure (SGS), typically estimated by genotyping adults, integrate migration over multiple generations and measure the effective gene flow of populations. SGS results can be compared with direct ecological studies of dispersal or mating system to gain additional insights. When mismatches occur, simulations can be used to illuminate the causes of these mismatches. Here we report a SGS and simulation-based study of self-fertilization in Macrocystis pyrifera, the giant kelp. We found that...

Data from: The population genomics of archaeological transition in west Iberia: investigation of ancient substructure using imputation and haplotype-based methods

Rui Martiniano, Lara M. Cassidy, Ros Ó'Maoldúin, Russell McLaughlin, Nuno M. Silva, Licinio Manco, Daniel Fidalgo, Tania Pereira, Maria J. Coelho, Miguel Serra, Joachim Burger, Rui Parreira, Elena Moran, Antonio C. Valera, Eduardo Porfirio, Rui Boaventura, Ana M. Silva & Daniel G. Bradley
We analyse new genomic data (0.05–2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200–3500 BC) to the Middle Bronze Age (1740–1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in...

Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia

Sophie Arnaud-Haond, Tania Aires, Rui Candeias, Sara J. L. Teixeira, Carlos M. Duarte, Myriam Valero & Ester A. Serrão
Successful prevention and mitigation of biological invasions requires retracing the initial steps of introduction, as well as understanding key elements enhancing the adaptability of invasive species. We studied the genetic diversity of the green alga Caulerpa taxifolia and its associated bacterial communities in several areas around the world. The striking congruence of α and ß diversity of the algal genome and endophytic communities reveals a tight association, supporting the holobiont concept as best describing the...

Genetic affinities and biogeography of putative Levantine-endemic seaweed Treptacantha rayssiae (Ramon) M.Mulas, J.Neiva & A.Israel, comb. nov. (Phaeophyceae)

Martina Mulas, João Neiva, Sofia Sadogurska, Enric Ballesteros, Ester Serrão, Gil Rilov & Alvaro Israel
Cystoseira sensu lato C.Agardh (Ochrophyta) forests are important habitat formers in the Mediterranean Sea, but they have mostly been studied in the western basin where many species are under decline due to human pressures. In the eastern basin, where fewer species occur, Cystoseira rayssiae Ramon was described in the year 2000 as an endemic species, based on morphological characteristics from herbaria samples collected on the Israeli coast. No further investigations have been conducted on this...

Data from: A low-latitude species pump: Peripheral isolation, parapatric speciation and mating-system evolution converge in a marine radiation

Susana C. Almeida, João Neiva, Filipe Sousa, Neusa Martins, Cymon J. Cox, José Melo-Ferreira, Michael D. Guiry Guiry, Ester A. Serrão & Gareth A. Pearson
Geologically recent radiation can shed light on speciation processes, but incomplete lineage sorting and introgressive gene flow render accurate evolutionary reconstruction and interpretation challenging. Independently evolving metapopulations of low-dispersal taxa may provide an additional level of phylogeographic information, given sufficiently broad sampling and genome-wide sequencing. Evolution in the marine brown algal genus Fucus in the south-eastern Atlantic was shaped by Quaternary climate-driven range shifts. Over this timescale, divergence and speciation occurred against a background of...

Data from: Weather and topography regulate the benefit of a conditionally helpful parasite

Jonathan Monsinjon, Christopher McQuaid, Katy Nicastro, Laurent Seuront, Mauricio Oróstica & Gerardo Zardi
Heat-induced mass mortalities involving ecosystem engineers may have long-lasting detrimental effects at the community level, eliminating the ecosystem services they provide. Intertidal mussels are ecologically and economically valuable with some populations facing unprecedented heat-induced mass mortalities. Critically, mussels are also frequently infested by endolithic parasites that modify shell albedo, hence reducing overheating and mortality rates under heat stress. Using a biophysical model, we explored the topographical and meteorological conditions under which endolithically-driven thermal buffering becomes...
