Data from: Testing the divergent adaptation of two congeneric tree species on a rainfall gradient using eco-physio-morphological traitsAnaïs-Pasiphaé Gorel, Kathy Steppe, Hans Beeckman, Niels J.F. De Baerdemaeker, Jean-Louis Doucet, Gauthier Ligot, Kasso Daïnou & Adeline Fayolle.
In tropical Africa, evidence of widely distributed genera transcending biomes or habitat boundaries has been reported. The evolutionary processes that allowed these lineages to disperse and adapt into new environments are far from being resolved. To better understand these processes, we propose an integrated approach, based on the eco-physio-morphological traits of two sister species with adjacent distributions along a rainfall gradient. We used wood anatomical traits, plant hydraulics (vulnerability to cavitation, wood volumetric water content...
Highlighting convergent evolution in morphological traits in response to climatic gradient in African tropical tree species: the case of genus Guibourtia BennFelicien Tosso, Jean-Louis Doucet, Kasso Daïnou, Adeline Fayolle, Alain Hambuckers, Charles Doumenge, Honoré Agbazahou, Piet Stoffelen & Olivier Hardy
Adaptive evolution is a major driver of organism diversification but the links between phenotypic traits and environmental niche remains little documented in tropical trees. Moreover, trait-niche relationships are complex because a correlation between the traits and environmental niches displayed by a sample of species may result from (1) convergent evolution if different environmental conditions have selected different sets of traits, and/or (2) phylogenetic inertia if niche and morphological differences between species are simply function of...
Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...
Data from: Maintenance of genetic and morphological identity in two sibling Syrrhopodon species (Calymperaceae, Bryopsida) despite extensive introgressionMarta R. Pereira, Alice Ledent, Patrick Mardulyn, Charles E. Zartman & Alain Vanderpoorten
Bryophytes are a group of land plants wherein the role of hybridization has long been challenged. Using Genotyping by Sequencing to circumvent the lack of molecular variation at selected loci previously used for phylogeny and morphology, we determine the level of genetic and morphological divergence and reproductive isolation between the sibling Syrrhopodon annotinus and S. simmondsii (Calymperaceae, Bryopsida) that occur in sympatry but in different habitats in lowland Amazonian rainforests. A clear morphological differentiation and...
Data from: Divergent evolutionary morphology of the axial skeleton as a potential key innovation in modern cetaceansAmandine Gillet, Bruno Frederich & Eric Parmentier
Cetaceans represent the most diverse clade of extant marine tetrapods. Although restructuring of oceans could have contributed to their diversity, other factors might also be involved. Similar to ichthyosaurs and sharks, variation of morphological traits could have promoted the colonization of new ecological niches and supported their diversification. By combining morphological data describing the axial skeleton of 73 cetacean species with phylogenetic comparative methods, we demonstrate that the vertebral morphology of cetaceans is associated to...
Data from: Seed and pollen dispersal distances in two African legume timber trees and their reproductive potential under selective loggingOlivier J. Hardy, Boris Delaide, Hélène Hainaut, Jean-François Gillet, Pauline Gillet, Esra Kaymak, Nina Vankerckhove, Jérôme Duminil & Jean-Louis Doucet
The natural regeneration of tree species depends on seed and pollen dispersal. To assess if limited dispersal could be critical for the sustainability of selective logging practices, we performed parentage analyses in two Central African legume canopy species displaying contrasted floral and fruit traits: Distemonanthus benthamianus and Erythrophleum suaveolens. We also developed new tools linking forward dispersal kernels with backward migration rates to better characterize long-distance dispersal. Much longer pollen dispersal in D. benthamianus (mean...
Data from: Personality and gonadal development as sources of individual variation in response to GnRH challenge in female great titsSamuel P. Caro, Charlotte A. Cornil, Kees Van Oers & Marcel E. Visser
Seasonal timing of reproduction is a key life-history trait, but we know little about the mechanisms underlying individual variation in female endocrine profiles associated with reproduction. In birds, 17β-estradiol is a key reproductive hormone that links brain neuroendocrine mechanisms, involved in information processing and decision making, to downstream mechanisms in the liver, where egg-yolk is produced. Here we test, using a simulated induction of the reproductive system through a GnRH-challenge, whether the ovary of pre-breeding...
Data from: Resolution of the ordinal phylogeny of mosses using targeted exons from organellar and nuclear genomesYang Liu, Matthew G. Johnson, Cymon J. Cox, Rafael Medina, Nicolas Devos, Alain Vanderpoorten, Lars Hedenäs, Neil E. Bell, James R. Shevock, Blanka Aguero, Dietmar Quandt, Norman J. Wickett, A. Jonathan Shaw & Bernard Goffinet
Mosses are a highly diverse lineage of land plants, whose diversification, spanning at least 400 million years, remains phylogenetically ambiguous due to the lack of fossils, massive early extinctions, late radiations, limited morphological variation, and conflicting signal among previously used markers. Here, we present phylogenetic reconstructions based on complete organellar exomes and a comparable set of nuclear genes for this major lineage of land plants. Our analysis of 142 species representing 29 of the 30...
