Continued adaptation of C4 photosynthesis after an initial burst of changes in the Andropogoneae grassesMatheus Bianconi, Jan Hackel, Maria Vorontsova, Adriana Alberti, Watchara Arthan, Sean Burke, Melvin Duvall, Elizabeth Kellogg, Sébastien Lavergne, Michael McKain, Alexandre Meunier, Colin Osborne, Paweena Traiperm, Pascal-Antoine Christin & Guillaume Besnard
C4 photosynthesis is a complex trait that sustains fast growth and high productivity in tropical and subtropical conditions and evolved repeatedly in flowering plants. One of the major C4 lineages is Andropogoneae, a group of ~ 1,200 grass species that includes some of the world's most important crops and species dominating tropical and some temperate grasslands. Previous efforts to understand C4 evolution in the group have compared a few model C4 plants to distantly related...
Pathogen-mediated selection favours the maintenance of innate immunity gene polymorphism in a widespread wild ungulateErwan Quéméré, Pauline Hessenauer, Maxime Galan, Marie Fernandez, Joël Merlet, Yannick Chaval, Nicolas Morellet, Hélène Verheyden, Emmanuelle Gilot-Fromont & Nathalie Charbonnel
Toll-like Receptors (TLR) play a central role in recognition and host frontline defence against a wide range of pathogens. A number of recent studies have shown that TLR genes (Tlrs) often exhibit large polymorphism in natural populations. Yet, there is little knowledge on how this polymorphism is maintained and how it influences disease susceptibility in the wild. In previous work, we showed that some Tlrs exhibit similarly high levels of genetic diversity as genes of...
Aim: Exploring the drivers of the successful ongoing expansion of the golden jackal across Europe is essential to understand the species’ trophic ecology. We analysed which climatic and environmental factors affected the dietary composition of golden jackals and compared these drivers in the species’ historic and recently colonised distribution ranges. Location: Eurasia. Taxon: golden jackal (Canis aureus). Methods: Using 40 published data sets, we modelled the diet composition using 13 food categories based on the...
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...
Data from: Elevational distribution of birds in an Eastern African montane environment as governed by temperature, precipitation, and habitat availabilityYntze Van Der Hoek, Clélia Sirami, Emmanuel Faida, Valens Musemakweli & Deogratias Tuyisingize
We conducted annual point counts of birds between 2013 and 2018 at 297 plots across habitats and elevations (2,416-4,303 m) in Volcanoes National Park, Rwanda. These data were subsequently used to determine elevational and habitat preferences via indicator analyses, and to model abundance distributions as a function of temperature, precipitation, habitat availability, and congeneric competition. Of 35 focal species, we found 20 species to be particularly associated with narrow elevational range (<300 m) and 24...
A combined microbial and biogeochemical dataset from high-latitude ecosystems with respect to methane cycleMaialen Barret, Laure Gandois, Frederic Thalasso, Karla Martinez Cruz, Armando Sepulveda Jauregui, Céline Lavergne, Roman Teisserenc, Polette Aguilar, Oscar Gerardo-Nieto2, Claudia Etchebehere, Bruna Martins Dellagnezze, Patricia Bovio-Winkler, Gilberto Fochesatto, Nikita Tananaev, Mette Svenning, Christophe Seppey, Alexander Tveit, Rolando Chamy, María Soledad Astorga-España, Andrés Mansilla, Anton Van De Putte, Maxime Sweetlove, Alison E Murray & Léa Cabrol
High latitudes are experiencing intense ecosystem changes with climate warming. The underlying methane (CH4) cycling dynamics remain unresolved, despite its crucial climatic feedback. Atmospheric CH4 emissions are heterogeneous, resulting from local geochemical drivers, global climatic factors, and microbial production/consumption balance. Holistic studies are mandatory to capture CH4 cycling complexity. Here, we report a large set of integrated microbial and biogeochemical data from 396 samples, using a concerted sampling strategy and experimental protocols. The study followed...
