Comparative analysis of spatial genetic structure in an ant-plant symbiosis reveals a tension zone and highlights speciation processes in tropical Africa

distance pollen transport from North America to Greenland is observed in association with wet 20 deposition. Conclusion

Firstly, in order to assess the structure of genetic diversity among wild Amazonian rubber tree populations, a sample of 307 genotypes from 21 locations was analyzed with

Modern Criollo and Nacional are in fact hybrid types resulting from introgression of respectively Forastero (reduced number of genotypes) in the ancestral Criollo and of

The specific objectives were to (1) study the current status of the genetic diversity harboured in the orchard, in the aerial part and rootstocks; (2) confirm the existence of

A total of 100 plus trees were phenotypically selected (based on vitality, growth, and stem form) from 43 population sites (one to five trees per site) at the northern range of

 A cluster analysis on MLVA-19 profiles (DAPC in R::adegenet) identified 12 clusters  Each cluster corresponds to a single lineage : DAPC.4, 5,11 = SL I; DAPC.1,2,3,8= SL II. 

This tension zone may have stabilized at a climatic transition (between boreal and austral seasonal regimes), and matches patterns of genetic structure previously observed in

Ainsi il est possible d’analyser les conséquences du choix d’une tarification et d’un paramétrage sur différents objectifs qui peuvent être poursuivis : le niveau de consommation
