Data from: Cultural flies: conformist social learning in fruit flies predicts long-lasting mate-choice traditionsEtienne Danchin, Sabine Nöbel, Arnaud Pocheville, Anne-Cecile Dagaeff, Léa Demay, Mathilde Alphand, Sarah Ranty-Roby, Lara Van Renssen, Magdalena Monier, Eva Gazagne, Mélanie Allain & Guillaume Isabel
Despite theoretical justification for the evolution of animal culture, there is still scant empirical evidence for it beyond mammals and birds, and we still know little about the process of cultural inheritance. Here, we propose a mechanism-driven definition of animal culture and test it in the fruit fly. We found that fruit flies have five cognitive capacities that enable them to transmit mating preferences culturally across generations, potentially fostering persistent traditions (the main marker of...
Polycotylidae is a clade of plesiosaurians that appeared during the Early Cretaceous and became speciose and abundant early in the Late Cretaceous. However, this radiation is poorly understood. Thililua longicollis from the Middle Turonian of Morocco is an enigmatic taxon possessing an atypically long-neck and, as originally reported, a series of unusual cranial features that cause unstable phylogenetic relationships for polycotylids. We reinterpret the holotype specimen of Thililua longicollis and clarify its cranial anatomy. Thililua...
Data from: A genome-wide data assessment of the African lion (Panthera leo) population genetic structure and diversity in TanzaniaNathalie Smitz, Olivia Jouvenet, Fredrick Ambwene Ligate, William-George Crosmary, Dennis Ikanda, Philippe Chardonnet, Alessandro Fusari, Kenny Meganck, François Gillet, Mario Melletti & Johan R. Michaux
The African lion (Panthera leo), listed as a vulnerable species on the IUCN Red List of Threatened Species (Appendix II of CITES), is mainly impacted by indiscriminate killing and prey base depletion. Additionally, habitat loss by land degradation and conversion has led to the isolation of some subpopulations, potentially decreasing gene flow and increasing inbreeding depression risks. Genetic drift resulting from weakened connectivity between strongholds can affect the genetic health of the species. In the...
Data from: Architectural differences associated to functional traits among 45 coexisting tree species in central AfricaGrace Jopaul Loubota Panzou, Gauthier Ligot, Sylvie Gourlet-Fleury, Jean-Louis Doucet, Eric Forni, Jean-Joël Loumeto & Adeline Fayolle
1. Architectural traits that determine the light captured in a given environment are an important aspect of the life-history strategies of tropical tree species. In this study, we examined how interspecific variation in architectural traits is related to the functional traits of 45 coexisting tree species in central Africa. 2. At the tree level, we measured tree diameter, total height and crown dimensions for an average of 30 trees per species (range 14–72, total 968...
Data from: Performance of glomerular filtration rate estimation equations in Congolese healthy adults: inopportunity of ethnic correctionJustine B. Bukabau, Ernest K. Sumaili, Etienne Cavalier, Hans Pottel, Bejos Kifakiou, Aliocha Nkodila, Jean-Robert R Makulo, Vieux M. Mokoli, Chantal V. Zinga, Augustin L. Longo, Yannick M. Engole, Yannick M. Nlandu, François B. Lepira, Nazaire M. Nseka, Jean-Marie Krzesinski, Pierre Delanaye, Jean Robert R. Makulo & Jean Marie Krzesinski
Context and objective: In the estimation of glomerular filtration rate (GFR), ethnicity is an important determinant. However, all existing equations have been built solely from Caucasian and Afro-American populations and they are potentially inaccurate for estimating GFR in African populations. We therefore evaluated the performance of different estimated GFR (eGFR) equations in predicting measured GFR (mGFR). Methods: In a cross-sectional study, 93 healthy adults were randomly selected in the general population of Kinshasa, Democratic Republic...
Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forestsLuc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...
Data from: Timing of perineuronal nets development in the zebra finch song control system correlates with developmental song learningGilles Cornez, Elisabeth Jonckers, Sita M. Ter Haar, Annemie Van Der Linden, Charlotte A. Cornil & Jacques Balthazart
The appearance of perineuronal nets (PNN) represents one of the mechanisms that contribute to the closing of sensitive periods for neural plasticity. This relationship has mostly been studied in the ocular dominance model in rodents. Previous studies also indicated that PNN might control neural plasticity in the song control system (SCS) of songbirds. To further elucidate this relationship, we quantified PNN expression and their localization around parvalbumin interneurons at key time-points during ontogeny in both...
Data from: Understanding the recruitment response of juvenile Neotropical trees to logging intensity using functional traitsJ. Aaron Hogan, Bruno Hérault, Bénédicte Bachelot, Anaїs Gorel, Marianne Jounieaux & Christopher Baraloto
Selective-logging remains a widespread practice in tropical forests, yet the long-term effects of timber-harvest on juvenile tree (i.e., sapling) recruitment across the hundreds of species occurring in most tropical forests, remain difficult to predict. This uncertainty could potentially exacerbate threats to some of the thousands of timber-valuable tree species in the Amazon. Our objective was to determine to what extent long-term responses of tree species regeneration in logged forests can be explained by their functional...
