Abstract There is growing interest among conservationists in biodiversity mapping based on stacked species distribution models ( SSDM s), a method that combines multiple individual to produce community‐level model. However, no user‐friendly interface specifically designed provide the basic tools needed fit such was available until now. The “ ssdm ” package computer platform implemented r providing range of methodological approaches and parameterisation at each step building : e.g....
Abstract Human activities modify the disturbance regimes of tropical forests. Since forests host high biological diversity, understanding role biodiversity in ecosystem recovery pathways and underlying ecological mechanisms is crucial to predict fate ecosystems. Studies relying on regularly censused forest plots, rarely include disturbed forests, are not long enough assess long‐term dynamics often lack repeatability. We used an individual‐based model growth effect species functional...
Somatic mutations potentially play a role in plant evolution, but common expectations pertaining to somatic remain insufficiently tested. Unlike most animals, the germline is assumed be set aside late development, leading expectation that plants accumulate along growth. Therefore, several predictions were made on fate of mutations: have generally low frequency tissues; at high higher chance intergenerational transmission; branching topology tree dictates mutation distribution; and exposure...
Abstract Effective population size ( N e ) is a pivotal evolutionary parameter with crucial implications in conservation practice and policy. Genetic methods to estimate have been preferred over demographic because they rely on genetic data rather than time‐consuming ecological monitoring. Methods based linkage disequilibrium (LD), particular, become popular as require single sampling provide estimates that refer recent generations. A software program the LD method, GONE, looks particularly...
Tropical forests shelter the highest species diversity worldwide, although genus is lower than expected. In species‐rich genera, complexes are composed of closely‐related that share large amounts genetic variation. Despite key role in diversification, evolution and functioning ecological communities, little known on why arise how they maintained Neotropical forests. Examining individual phenotypes vary along environmental gradients, within among complexes, can reveal processes allowing...
Despite a long history of vegetation modelling, robustly simulating dynamics remains complex but highly needed task. There is growing consensus that models need to better integrate forest structure, diversity and ecosystem functioning tackle this research challenge. However, has been hindered by coarse-grained representation subsequent difficulties assimilate field data. Here I will present recent developments in an individual- trait-based model dynamics, TROLL 4.0. discuss the modelling...
Abstract Closely related tree species that grow in sympatry are abundant rainforests. However, little is known of the ecoevolutionary processes govern their niches and local coexistence. We assessed genetic delimitation closely sympatric belonging to two Neotropical complexes investigated genomic adaptation a fine‐scale topographic gradient with associated edaphic hydrologic features. Combining LiDAR‐derived topography, inventories, single nucleotide polymorphisms (SNPs) from gene capture...
The dry and wet seasons in the Neotropics have strong effects on soil water nutrient availability, as well forest dynamics. Despite these major ecology, little is known how leaf traits vary throughout tropical rainforest trees. Here, we investigated influence of seasonal variations climate characteristics trait variation two tree species. We measured traits, thickness mass per area, 401 individuals species Symphonia (Clusiaceae) Paracou research station French Guiana lowland rainforest....

Tropical forest dynamics are driven by growth and survival strategies of tree species in relation to treefall gaps; however, the ecological evolutionary roles intraspecific variation response gaps remain unexplored. Here, we associated genomic data three related genus Symphonia a French Guiana with (1) each individual tree's potential, (2) its light competition environment estimated based on 33 years monitoring plots covering 120 ha. We show that trees within have genetically determined...
1. Mutation, the source of genetic diversity, is raw material evolution; however, mutation process remains understudied, especially in plants. Using both a simulation and reanalysis framework, we set out to explore demonstrate improved performance variant callers developed for cancer research compared single nucleotide polymorphism (SNP) detecting de novo somatic mutations.
The increasing online availability of biodiversity data and advances in ecological modeling have led to a proliferation open‐source tools. In particular, R packages for species distribution continue multiply without guidance on how they can be employed together, resulting high fidelity researchers one or several packages. Here, we assess the wide variety software models (SDMs) highlight work together diversify expand analyses each step workflow. We also introduce new package ‘sdmverse'...
Abstract Background and Aims Intraspecific variability in leaf water-related traits remains little explored despite its potential importance the context of increasing drought frequency severity. Studies comparing intra- interspecific often rely on inappropriate sampling designs that result non-robust estimates, mainly owing to an excess species/individual ratio community ecology or, contrary, individual/species population ecology. Methods We carried out virtual testing three strategies...

Abstract. TROLL 4.0 is an individual-based forest dynamics model that jointly simulates the structure, diversity and functioning of tropical forests, including their water balance, carbon fluxes leaf phenology, while accounting for intraspecific trait variation a large number species.
