Heuertz, Myriam; Caron, Henri; Scotti-Saintagne, Caroline; Pétronelli, Pascal; Engel, Julien; Tysklind, Niklas; Miloudi, Sana; Gaiotto, Fernanda A.Background and aims – The evolutionary history of Amazonia’s hyperabundant tropical tree species, also known as “hyperdominant” species, remains poorly investigated. We assessed whether the hyperdominant Eschweilera coriacea (DC.) S.A.Mori (Lecythidaceae) represents a single genetically cohesive species, and how its genetic constitution relates to other species from the same clade with which it occurs sympatric...
Monitoring genetic diversity in tropical trees with multilocus dominant markers
Kremer, Antoine; Caron, Henri; Cavers, Stephen; Colpaert, Nathalie; Gheysen, Godelieve D.R.; Gribel, Rogério; Lemes, Maristerra R.; Lowe, Andrew J.Since no universal codominant markers are currently available, dominant genetic markers, such as amplified fragment length polymorphism (AFLP), are valuable tools for assessing genetic diversity in tropical trees. However, the measurement of genetic diversity (H) with dominant markers depends on the frequency of null homozygotes (Q) and the fixation index (F) of populations. While Q can be estimated for AFLP lo...
Standardized genetic diversity-life history correlates for improved genetic res...
Lowe, Andrew J.; Breed, Martin F.; Caron, Henri; Colpaert, Nathalie; Dick, Christopher W.; Finegan, Bryan; Gardner, Mike; Gheysen, Godelieve D.R.Aim: Life history traits and range size are key correlates of genetic diversity in trees. We used a standardized sampling protocol to explore how life history traits and range size relate to the magnitude, variance and structuring (both between- and within-population) of genetic diversity in Neotropical tree species. Location: The Neotropics. Methods: We present a meta-analysis of new population genetic data ge...
Optimal sampling strategy for estimation of spatial genetic structure in tree p...
Cavers, Stephen; Degen, Bernd; Caron, Henri; Lemes, Maristerra R.; Margis, Rogério; Salgueiro, Fabiano; Lowe, Andrew J.Fine-scale spatial genetic structure (SGS) in natural tree populations is largely a result of restricted pollen and seed dispersal. Understanding the link between limitations to dispersal in gene vectors and SGS is of key interest to biologists and the availability of highly variable molecular markers has facilitated fine-scale analysis of populations. However, estimation of SGS may depend strongly on the type ...

Nuclear and plastid SNP markers for tracing Cedrela timber in the tropics
Paredes-Villanueva, Kathelyn; Blanc-Jolivet, Celine; Mader, Malte; Honorio Coronado, Eurídice N.; Garcia-Davila, Carmen; Sebbenn, Alexandre M.Made available in DSpace on 2019-10-06T15:52:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Illegal logging and trade of timber are major worldwide concerns, resulting in biodiversity and economic losses. Tropical tree species in the genus Cedrela, which have historically been heavily exploited, are still often illegally traded and there is an urgent need to develop tools to verify the origin ...
