L’activité de pépinière est en plein essor dans les villes du Burkina Faso. Toutefois, cette activité demeure peu connue des habitants. L’objectif notre étude était d’évaluer l’impact secteurs phytogéographiques sur la diversité espèces produites et valeur socio-économique pépinières Pour une meilleure connaissance ces pépinières, 166 ont été identifiées étudiées à travers un inventaire florist...

Anatomical characters of Cenozoic pine seed cones are known mainly from North American fossils, while data on cone anatomy species Asia remain scarce. To date, only one Pinus the Miocene eastern China has been studied using micro-computed tomography (micro-CT). A new fossil-species, prehwangshanensis sp. nov., mummified upper Pleistocene South is described a combination scanning electron micros...

Pinus trifolia Miki 1939 (Pinaceae) was originally proposed based on seed cones from the upper Miocene of Aichi and Gifu Prefectures, central Japan. However, before the publication of P. trifolia, a different name (Pinus fujiii (Yasui) Miki) was given to a female cone with the same morphology. On the other hand, P. fujiii auct. non (Yasui) Miki has been used for seed cones with different morpho...

Assessing priorities is the most important action in conservation programs. Rudimentary, mapping of diversity, and distribution patterns have been used to set priorities on diverse scales. The distribution patterns of plant taxa, largely reflect an actual ecological niche. Convolvulaceae s.str exhibits cosmopolitan dispersal of diverse life forms and includes 50–60 genera comprising 1600–1700 s...

To assess the influence of zoogeographic factors and life-history parameters (effective population size, generation length, and dispersal) on the evolutionary genetic structure of marine fishes in the southeastern USA, phylogeographic patterns of mitochondrial DNA (mtDNA) were compared between disjunct Atlantic and Gulf of Mexico populations in three coastal marine fishes whose juveniles requir...

Tree mortality is a critical ecological process with fundamental implications for forest dynamics and carbon storage (e.g. McDowell et al., 2018). High rates are known to strongly limit above-ground tropical biomass Johnson 2016; McMahon 2019) impact the structure composition of communities (Esquivel-Muelbert 2019). Thus, better understanding causes tree death mechanistic global change impacts ...
