Data from: Distinct mesoderm migration phenotypes in extra-embryonic and embryonic regions of the early mouse embryo

Bechara Saykali, Navrita Mathiah, Wallis Nahaboo, Marie-Lucie Racu, Latifa Hammou, Matthieu Defrance & Isabelle Migeotte
In the gastrulation mouse embryo, epiblast cells delaminate at the primitive streak to form mesoderm and definitive endoderm, through an epithelial-mesenchymal transition. Mosaic expression of a membrane reporter in nascent mesoderm enabled recording cell shape and trajectory through live imaging. Upon leaving the streak, cells changed shape and extended protrusions of distinct size and abundance depending on the neighboring germ layer, as well as the region of the embryo. Embryonic trajectories were meandrous but directional,...

Data from: Maintenance of genetic and morphological identity in two sibling Syrrhopodon species (Calymperaceae, Bryopsida) despite extensive introgression

Marta 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...

Highlighting convergent evolution in morphological traits in response to climatic gradient in African tropical tree species: the case of genus Guibourtia Benn

Felicien 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...

Data from: Seed and pollen dispersal distances in two African legume timber trees and their reproductive potential under selective logging

Olivier 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: Ocean warming and acidification alter the behavioural response to flow of the sea urchin Paracentrotus lividus

Mishal Cohen-Rengifo, Antonio Agüera, Tjeerd Bouma, Saloua M‘Zoudi, Patrick Flammang & Philippe Dubois
Ocean warming (OW) and acidification (OA) are intensively investigated as they pose major threats to marine organism. However, little effort is dedicated to another collateral climate change stressor, the increased frequency and intensity of storm events, here referred to as intensified hydrodynamics. A 2-month experiment was performed to identify how OW and OA (temperature: 21°C; pHT: 7.7, 7.4; control: 17°C-pHT7.9) affect the resistance to hydrodynamics in the sea urchin Paracentrotus lividus using an integrative approach...
