Adaptation to drought is coupled with slow growth, but independent from phenology in marginal silver fir (Abies alba Mill.) populations

Katalin Csillery, Nina Buchmann & Bruno Fady
Drought is one of the most important selection pressures for forest trees in the context of climate change. Yet, the different evolutionary mechanisms, and their environmental drivers, by which certain populations become more drought tolerant than others is still little understood. We studied adaptation to drought in 16 silver fir (Abies alba Mill.) populations from the French Mediterranean Alps by combining observations on seedlings from a large scale greenhouse experiment (N=8199) and on adult tress...

Complex biotic interactions mediated by shrubs: revisiting the stress-gradient hypothesis and consequences for tree seedling survival

Arthur Guignabert, Laurent Augusto, Maya Gonzalez, Christophe Chipeaux & Florian Delerue
1. Using nurse shrubs to improve tree seedling establishment in stressed environments is a common practice in forestry. Recent refinements of the stress-gradient hypothesis suggest that positive nurse effects occur under intermediate stress and decline in the harshest conditions. Additionally, indirect facilitation is expected in low-stressed/productive systems according to the initial stress-gradient hypothesis. However, there have been fewer investigations into the use of nurse shrubs to decrease herbivore impacts in stressed systems compared with the...

Data from: Canonical correlations reveal adaptive loci and phenotypic responses to climate in perennial ryegrass

José L. Blanco-Pastor, Philippe Barre, Thomas Keep, Thomas Ledauphin, Abraham Escobar-Gutiérrez, Anna Maria Roschanski, Evelyn Willner, Klaus Dehmer, Matthew Hegarty, Hilde Muylle, Elisabeth Veeckman, Klaas Vandepoele, Tom Ruttink, Isabel Roldán-Ruiz, Stéphanie Manel & Jean-Paul Sampoux
Germplasm from perennial ryegrass (Lolium perenne L.) natural populations is useful for breeding because of its adaptation to a wide range of climates. Climate-adaptive genes can be detected from associations between genotype, phenotype and climate but an integrated framework for the analysis of these three sources of information is lacking. We used two approaches to identify adaptive loci in perennial ryegrass and their effect on phenotypic traits. First, we combined Genome-Environment Association (GEA) and GWAS...

The shape of the predator biomass distribution affects biological pest control services in agricultural landscapes

Noémie Ostandie, Lucile Muneret, Brice Giffard, Denis Thiéry & Adrien Rusch
1. Understanding how community composition of service-providing organisms affects ecosystem functioning is a key challenge in ecology. Although it has been proposed that taxonomic diversity and functional traits mediate this relationship, how several facets of community structure affect the delivery of key ecosystem services remains to be explored. 2. In this study, we investigated how abundance, taxonomic richness as well as the shape of biomass distribution in predator communities affect biological pest control services in...

Weak founder effects but significant spatial genetic imprint of recent contraction and expansion of European beech populations.

Sylvie Oddou-Muratorio, Tonya Lander, Etienne Klein & Anne Roig
Understanding the ecological and evolutionary processes occurring during species range shifts is important in the current context of global change. Here, we investigate the interplay between recent expansion, gene flow and genetic drift, and their consequences for genetic diversity and structure at landscape and local scales in European beech (Fagus sylvatica L.) On Mont Ventoux, South-Eastern France, we located beech forest refugia at the time of the most recent population minimum, approximately 150 years ago,...

Least‐cost path analysis for urban greenways planning: a test with moths and birds across two habitats and two cities

Manon Balbi, Solène Croci, Eric J. Petit, Alain Butet, Romain Georges, Luc Madec, Jean-Pierre Caudal & Aude Ernoult
1. One of the major planning tools to respond to urban landscape fragmentation is the development of ecological corridors, i.e. interconnected networks of urban green and blue spaces. Least-cost paths (LCP) appear to be an easy and appropriate resistance-based modeling method to respond to urban planners’ needs. However, the ecological validation of urban corridors using LCP is rarely performed and needs to be generalized to different species, habitats and cities. 2. We developed an experimental...

Fonio millet genome unlocks African orphan crop diversity for agriculture in a changing climate

Michael Abrouk, Hanin Ibrahim Ahmed, Philippe Cubry, Denisa Šimoníková, Stéphane Cauet, Yveline Pailles, Jan Bettgenhaeuser, Liubov Gapa, Nora Scarcelli, Marie Couderc, Leila Zekraoui, Nagarajan Kathiresan, Jana Čížková, Eva Hřibová, Jaroslav Doležel, Sandrine Arribat, Hélène Bergès, Jan Wieringa, Mathieu Gueye, Ndjido Kane, Christian Leclerc, Sandrine Causse, Sylvie Vancoppenolle, Claire Billot, Thomas Wicker … & Simon Krattinger
Sustainable food production in the context of climate change necessitates diversification of agriculture and a more efficient utilization of plant genetic resources. Fonio millet (Digitaria exilis) is an orphan African cereal crop with a great potential for dryland agriculture. Here, we established high-quality genomic resources to facilitate fonio improvement through molecular breeding. These include a chromosome-scale reference assembly and deep re-sequencing of 183 cultivated and wild Digitaria accessions, enabling insights into genetic diversity, population structure,...

Populations of arable weed species show intra-specific variability in germination base temperature but not in early growth rate

Jana Bürger & Nathalie Colbach
Key plant traits affecting growth performance can differ among and within species, influencing competitive plant community dynamics. We determined the intra-specific variability of germination base temperature among 13 arable weed species and the seedlings’ early post-emergence relative growth rate among 21 species in climate chamber and green house experiments. Intra-specific variability was quantified with two seed populations (originating from contrasting climate in Germany & France) for the germination base temperature of 6 species and for...

Data from: As time goes by: 20 years of changes in the aquatic macroinvertebrate metacommunity of Mediterranean river networks

Miguel Cañedo-Argüelles, Cayetano Guitiérrez-Cánovas, Raul Acosta, Daniel Castro, Núria Cid, Pau Fortuño, Antoni Munné, Cesc Múrria, Rita Rodrigues, Romain Sarremejane, Maria Soria, Pol Tarrats, Iraima Verkaik, Narcís Prat & Núria Bonada
Aim: to analyse temporal metacommunity dynamics in river networks in relation to hydrological conditions and dispersal. Location: 15 river reaches from the Llobregat, Besòs and Foix catchments in the North-Eastern Iberian Peninsula. Taxon: aquatic macroinvertebrates belonging to 99 different families. Methods: we sampled aquatic macroinvertebrate communities during spring in 20 consecutive years. We built two environmental distances (one related with water chemistry and another one with river flow regime) and two spatial distances (network distance...

European soil seed bank communities across a climate and land-cover gradient

Context European forests are expanding and becoming denser following the widespread abandonment of farmland and rural areas. Yet, little is known about the goods and services that spontaneous forest regrowth provide to people. Aims We assessed the changes in nature’s contributions to people (NCP) from spontaneous forest regrowth, i.e. forest expansion and densification, in South-West Europe. Methods We investigated 65 forest plots in four different landscapes with contrasting ecological and societal contexts. Two landscapes are...
