Species delimitation in closely related plant taxa can be challenging because (i) reproductive barriers are not always congruent with morphological differentiation, (ii) use of plastid sequences might lead to misinterpretation, (iii) rare species sampled. We revisited molecular-based the African genus Milicia, currently divided into M. regia (West Africa) and excelsa (from West East Africa). used 435 samples collected West, Central Africa. genotyped SNP SSR loci identify genetic clusters,...
Adaptive evolution is a major driver of organism diversification, but the links between phenotypic traits and environmental niche remain little documented in tropical trees. Moreover, trait-niche relationships are complex because correlation niches displayed by sample species may result from (a) convergent if different conditions have selected sets traits, and/or (b) phylogenetic inertia morphological differences simply function their divergence, which case does not imply any direct causal...
Premise of the study: Multiplexes nuclear microsatellite primers were developed to investigate population genetic structure and diversity in two exploited African rainforest trees: Entandrophragma candollei E. utile (Meliaceae). Methods Results: Microsatellite isolation was performed simultaneously on nonenriched genomic libraries after next‐generation sequencing. We 16 22 polymorphic markers for three four multiplexes, respectively. The number alleles ranged from 17 19 . Mean expected...
Abstract Characterization of the ecology endangered timber species is a crucial step in any forest management strategy. In this study, we described animal communities involved seed dispersal and predation high‐value Guibourtia tessmannii (Fabaceae; Detarioideae), which newly listed on Appendix II CITES . We compared between two sites (Bambidie Gabon Ma'an Cameroon). A total 101 hr direct observations 355 days camera trapping revealed that primate ( Cercopithecus nictitans ) hornbill...
Premise of the study: Nuclear microsatellites (nSSRs) were designed for Guibourtia tessmannii (Fabaceae, Caesalpinioideae), a highly exploited African timber tree, to study population genetic structure and gene flow. Methods Results: We developed 16 polymorphic nSSRs from genomic library tested in three populations G. two coleosperma . These display 14 alleles per locus (mean 8.94) Cross‐amplification tests nine congeneric species demonstrated that genus contains diploid polyploid species....
Introduction. En raison de la diminution des ressources en bois d’œuvre tropicaux, il convient d'améliorer les connaissances sur espèces ligneuses vue développer politiques d'exploitation réellement durables. Reconnu pour grande qualité son bois, Cylicodiscus gabunensis Harms (Fabaceae-Caesalpinioideae) est une essence à haute valeur socio-économique. Cet article dresse synthèse bibliographique relatives cette espèce mettre avant l’ensemble aspects méritant investigations scientifiques...
Microsatellites were designed and characterized in the African timber forest tree Terminalia superba (Combretaceae). Due to their high variability, these markers are suitable investigate gene flow patterns structure of genetic diversity.From a genomic library obtained by next-generation sequencing, seven monomorphic 14 polymorphic microsatellite loci developed. The microsatellites displayed two 27 alleles (mean 11.4; expected heterozygosity range 0.283-0.940, mean 0.736) one population from...
Les semences contenues dans le stock semencier du sol peuvent être trop petites pour quantifiées visuellement. essences concernées sont généralement identifiées lors d’essais de germination en pépinière, ce qui prend temps. Cette étude examine une nouvelle approche basée sur l'imagerie hyperspectrale proche infrarouge (PIR) couplée à des outils chimiométriques. Elle se concentre forêts humides africaines, est encore méconnu. Nous avons utilisé quatre-vingt-trois deux espèces sœurs,...
La présente thèse s’intéresse aux mécanismes à l’origine de la diversification des espèces d’arbres tropicaux. Elle utilise le genre Guibourtia Benn. (Fabaceae-Detarioideae) comme modèle biologique afin comprendre les historiques, biologiques et environnementaux diversité ce genre. Plus particulièrement, elle vise, d’une part, étudier, au niveau interspécifique, rôle relatif forces évolutives neutres sélection dans du et, d’autre intra-spécifique, questionner causes différenciation...
Introduction. Le présent travail dresse une synthèse des connaissances sur le genre Dialium (Fabaceae, Dialioideae) dans la région guinéo-congolaise. Il examine plus particulièrement possibilité de valoriser durablement bois ces espèces et les coproduits leur transformation en vue diminuer pression d’autres durs dont populations se raréfient. Littérature. Bien qu’il n’existe pas consensus parmi botanistes, comprendrait 44 espèces, 22 seraient inféodées à Les différences entre sont parfois...
Microsatellite primers (simple sequence repeats [SSRs]) were developed in Guibourtia ehie (Fabaceae, Detarioideae) to study population genetic structure and the history of African vegetation.We isolated 18 polymorphic SSRs from a nonenriched genomic library. This set primer pairs was tested on four populations, results showed two 16 alleles per locus with mean observed expected heterozygosities 0.27 ± 0.05 0.57 0.05, respectively. Cross-amplification tests 13 congeneric species successful...
Many commercial species are light-demanding and regenerate with difficulty in natural forest, which compromises the sustainability of logging. Okan, Cylicodiscus gabunensis Harms is one most exploited Central Africa its regeneration deficient evergreen forest. In forest concessions, enrichment logging gaps has already been tested but only for a few species. Mixed results have obtained because ability seedlings to emerge from competing vegetation depends on species, environment silvicultural...
