Local phylogenetic signal in Dutch habitats and other data from Prinzing et al New Phytologist 2021

Prinzing Andreas
The functioning of present ecosystems reflects deep evolutionary history of locally co-occurring species if their functional traits show high phylogenetic signal (PS). However, we do not understand what drives local PS. We hypothesize that local PS is high in undisturbed and stressful habitats – either due to ongoing local assembly of species that maintained ancestral traits, or past evolutionary maintenance of ancestral traits within habitat species-pools, or both. We quantified PS and diversity of 10...

Third and fourth trophic level composition shift in an aphid-parasitoid-hyperparasitoid food web limits aphid control in an intercropping system

Emma Jeavons, Joan Van Baaren, Anne Le Ralec, Christelle Buchard, Franck Duval, Stéphanie Llopis, Estelle Postic & Cécile Le Lann
1. Understanding how resource diversification affects ecological interactions, food web structure and ecosystem functioning is essential in both fundamental and applied ecology. While plant diversification strategies (either in- or around-field) are often proposed in agricultural landscapes as practices to improve the biological control of herbivores by natural enemies, results remain variable and unsure. 2. Here, we studied the effect of an in-field diversification practice (the intercropping of leguminous crops within cereal fields, an increasingly common...

Checklists of endemic tracheophytes and bryophytes to the French Overseas Territories

Simon Veron, Carlos Rodrigues-Vaz, Elise Lebreton, Claudine Ah-Peng, Vincent Boullet, Hervé Chevillotte, Stephan Robbert Gradstein, Joël Jérémie, Elisabeth Lavocat-Bernard, Marc Lebouvier, Jean-Yves Meyer, Jérôme Munzinger, Odile Poncy, Louis Thouvenot, Guillaume Viscardi, Guillaume Léotard, Olivier Gargominy, Sébastien Leblond, Marc Pignal, Germinal Rouhan, Sandrine Tercerie, Vanessa Invernon & Serge Muller
A broad range of climatic and biogeographical conditions are represented in the French Overseas Territories, from sub-polar to equatorial, resulting in a high diversity of endemic species. We mobilized data from herbaria, floras, checklists, literature, the expertise of botanists and plant ecologists to compile the most complete dataset on endemic vascular plants and bryophytes in the 15 French Overseas Territories. To date, 3748 spermatophytes (seed plants), 244 pteridophytes (ferns and lycophytes) and 448 bryophytes are...

Eco-evolutionary outsiders: establishing in a distantly related neighbourhood delays and reorganizes nutrient recycling

Xu Pan, Mathieu Santonja, Pierre-Emmanuel Courty, Olaf Butenschön, Matty Berg, Phil Murray, Benjamin Yguel, Daphnée Brulé & Andreas Prinzing
Rapid environmental change forces long-lived plants like trees to immigrate into zones still occupied by phylogenetically distantly related species. Does such phylogenetic isolation (PI) change the trees’ ecosystem functioning such as litter decomposition? We studied oaks (Quercus petraea) of low and high PI, reciprocally transplanting their litters to identify effect of aboveground litter quality and belowground decomposer biota. Across 8 and 14 months we quantified decomposition (mass loss, C-loss and N-loss), decomposer biota (Acari, Collembola,...

Objective: To compare the clinical effectiveness of high- and low-efficacy treatments in patients with recently active and inactive secondary progressive multiple sclerosis (SPMS) after accounting for therapeutic lag. Methods: Patients treated with high- (natalizumab, alemtuzumab, mitoxantrone, ocrelizumab, rituximab, cladribine, fingolimod) or low-efficacy (interferon β, glatiramer acetate, teriflunomide) therapies after SPMS onset were selected from MSBase and OFSEP, two large observational cohorts. Therapeutic lag was estimated for each patient based on their demographic and clinical characteristics....

Challenges and opportunities of species distribution modelling of terrestrial arthropod predators

Stefano Mammola, Julien Pétillon, Axel Hacala, Jeremy Monsimet, Sapho-Lou Marti, Pedro Cardoso & Denis Lafage
Aim. Species distribution models (SDMs) have emerged as essential tools in the equipment of many ecologists, useful to explore species distributions in space and time and answering an assortment of questions related to biogeography, climate change biology and conservation biology. Historically, most SDM research concentrated on well-known organisms, especially vertebrates. In recent years, these tools are becoming increasingly important for predicting the distribution of understudied invertebrate taxa. Here, we reviewed the literature published on main...

Analyses on the fungus-farming termite, Macrotermes natalensis

Mark Harrison, Mireille Vassuer-Cognet, Sarah Seite, David Sillam-Dussès, Roland Lupoli, Alain Robert, Laure-Anne Poissonnier, Tom Van Dooren, Arnaud Lemainque, David Renault, Sebastien Acket, Muriel Andrieu, Jose Viscarra, Hei Sook Sul, Wilhelm De Beer & Erich Bornberg-Bauer
Kings and queens of eusocial termites can live for decades, while queens sustain a nearly maximal fertility. To investigate the molecular mechanisms underlying their long lifespan, we carried out transcriptomics, lipidomics and metabolomics in Macrotermes natalensis on sterile short-lived workers, long-lived kings and five stages spanning twenty years of adult queen maturation. Reproductives share gene expression differences from workers in agreement with a reduction of several aging-related processes, involving upregulation of DNA damage repair and...
