Estimating heritability in honeybees: comparison of three major methods based on empirical and simulated datasets

Hélène Jourdan-Pineau, Gaëlle Antoine, Julien Galataud, Hélène Delatte, Christophe Simiand & Johanna Clémencet
The genetic contribution to phenotypic variation (namely the heritability) affects the response to selection. In honeybee, the haplodiploid sex determination does not allow the straightforward use of classical quantitative genetics methods to estimate heritability and genetic correlation. Nevertheless, specific methods have been developed for about 40 years. In particular, sibling analyses are frequently used with three main methods: an historical model using the average colony relatedness, a half-sibs/full-sibs model and the more recent animal model....

Marie Sauvadet, Jean Trap, Gaëlle Damour, Claude Plassard, Karel Van Den Meersche, Raphaël Achard, Clémentine Allinne, Patrice Autfray, Isabelle Bertrand, Eric Blanchart, Péninna Deberdt, Séguy Enock, Jean-Daniel Essobo, Grégoire Freschet, Mickaël Hedde, Elias De Melo Virginio Filho, Bodovololona Rabary, Miora Rakotoarivelo, Richard Randriamanantsoa, Béatrice Rhino, Aude Ripoche, Elisabeth Rosalie, Stéphane Saj, Thierry Becquer, Philippe Tixier … & Jean-Michel Harmand
Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation....

Soil macroinvertebrate communities have been assessed worldwide using the standard ISO/TSBF sampling procedure. The Macrofauna database currently comprises 3694 sites distributed throughout 41 countries, from 55º S latitude to 57ºN, sea level to over 4000m in elevation, in total annual total rainfall regimes between 500 and >3000mm and 5 to 32ºC mean temperature. These communities are significantly influenced by climatic parameters, soil texture and vegetation cover. Abundance and diversity were highest in tropical rain forests...

In the first experiment (“crossing experiment”), the effect of Arsenophonus is...

Data from: Shade tree traits and microclimate modifications: Implications for pathogen management in biodiverse coffee agroforests

Stephanie Gagliardi, Jacques Avelino, Elias De Melo Virginio Filho & Marney Isaac
Diversified coffee agroforests modify microclimate conditions in comparison to monocultures, impacting the success of significant plant pathogens, such as Hemileia vastatrix, which causes coffee leaf rust (CLR). However, research is often limited to the dichotomous analysis of shaded agroforestry systems or unshaded monocultures, often overlooking the nuanced effect of shade tree trait diversity. Our study aims to determine the cumulative effects of shade tree canopy architectural characteristics and leaf functional traits in biodiverse agroforests on...

Complex adaptive architecture underlies adaptation to quantitative host resistance in a fungal plant pathogen

Jean Carlier
Plant pathogens often adapt to plant genetic resistance so characterization of the architecture underlying such an adaptation is required to understand the adaptive potential of pathogen populations. Erosion of banana quantitative resistance to a major leaf disease caused by polygenic adaptation of the causal agent, the fungus Pseudocercospora fijiensis, was recently identified in the northern Caribbean region. Genome scan and quantitative genetics approaches were combined to investigate the adaptive architecture underlying this adaptation. Thirty-two genomic...

Interspecific interactions regulate plant reproductive allometry in cereal-legume intercropping systems

Noémie Gaudio, Cyrille Violle, Xavier Gendre, Florian Fort, Rémi Mahmoud, Elise Pelzer, Safia Médiène, Henrik Hauggaard-Nielsen, Laurent Bedoussac, Catherine Bonnet, Guénaëlle Corre-Hellou, Antoine Couëdel, Philippe Hinsinger, Eric Steen Jensen, Etienne-Pascal Journet, Eric Justes, Bochra Kammoun, Isabelle Litrico, Nathalie Moutier, Christophe Naudin & Pierre Casadebaig
1. Calls for the application of ecological principles in agriculture have gained momentum. Intercropping systems are designed by growing two, or more, annual crop species in the same field, aiming for a better resource use efficiency. However, assembly rules for their design are lacking. Notably, it is unknown whether species performances are maximized during both the vegetative and reproductive phases given the sensitivity of reproductive allocation rules to resource limitation. Interestingly, ecological theory provides expectations...

Data from: Biogeographic history and habitat specialisation shape floristic and phylogenetic composition across Amazonian forests

Christopher Baraloto, Jason Vleminckx, Julien Engel, Pascal Petronelli, Nállarett Dávila, Marcos Ríos, Elvis Harry Valderrama Sandoval, Italo Mesones, Juan Ernesto Guevara Andino, Claire Fortunel, Elodie Allie, C. E. Timothy Paine, Aurélie Dourdain, Jean-Yves Goret, Oscar J. Valverde-Barrantes, Freddie Draper & Paul V. A. Fine
A major challenge remains to understand the relative contributions of history, dispersal and environmental filtering to the assembly of hyperdiverse communities across spatial scales. Here, we examine the extent to which biogeographical history and habitat specialization have generated turnover among and within lineages of Amazonian trees across broad geographic and environmental gradients. We replicated standardised tree inventories in 102 0.1-ha plots located in two distant regions - the western Amazon and the eastern Guiana shield....

Molecular Ecology https://doi.org/10.1111/mec.15897 " Many animals have evolved associations with symbiotic microbes that benefit the host through increased growth, lifespan, and survival. Some interactions are obligate (essential for survival) while others...

High tree diversity enhances light interception in tropical forests

Marina Melo Duarte, Caroline Isaac Ferreira Zuim, Taísi Bech Sorrini, Luís Eduardo Bernardini, Rafael De Andrade Moral, Joannes Guillemot, Catherine Potvin, Wagner Hugo Bonat, José Luiz Stape & Pedro Henrique Santin Brancalion
We used two forest plantation experiments, the Sardinilla site in Panama (containing monocultures, 2-, 3- and 5-species mixtures in the main plantation, established in 2001, and 6-, 9- and18-species mixtures in the high-diversity plantation, established in 2003), and the Anhembi site in Brazil (established in 2006, containing 20-, 58- and 114-species mixtures), to investigate the effects of forest tree richness on the amount and distribution (horizontal, vertical and temporal) of intercepted ligh (red:far-red ratio -...

Genotype-environment interactions shape leaf functional traits of cacao in agroforests

Marie Sauvadet, Adam Dickinson, Eduardo Somarriba, Wilbert Phillips-Mora, Rolando Cerda, Adam Martin & Marney Isaac
The outbreak of frosty (Moniliophthora roreri) and black pod (Phytophthora palmivora) in Central American cacao agroforests throughout the 1980s, led to the breeding of Theobroma cacao clones resistant to these diseases. However, while clonal disease resistance has been well documented, clonal adaptability to contrasting pedoclimates remains less understood. Plant functional responses to environmental constraints can be assessed by evaluating intraspecific trait variation (ITV), but trait-based approaches have rarely been implemented in genotype assessments. The objective...
