HAAS-EK, María Alejandra et al. Arboreal resprouting in the Calakmul, Campeche, Mexico tropical forest regeneration. Rev. biol. trop [online]. 2019, vol.67, n.1, pp.164-181. ISSN 0034-7744.  http://dx.doi.org/10.15517/rbt.v67i1.33092.

Detailed studies to understand recovering of Neotropical forests over time, through secondary succession, are still necessaries. Between acting mechanisms of regeneration in the tropical forests, the arboreal resprout predominates in woody species, with the advantage of restart the growth from still rooting plants, allowing the restoring of forest canopy. The study aim was to identify and quantify the tree species with resprouting capacity in different stages of secondary succession (tree-fallow) after the traditional milpa agricultural system, compared with tropical forest communities in the Calakmul Biosphere Reserve and, enlightening how these species influences the recovery of the composition of this ecosystem. Was calculated the proportions of species with or without resprouting by successional stage. There were 13 972 individuals (32 % resprouting and 68 % not resprouting) and 168 species (79 % resprouting and 21 % not resprouting), the percentage of individuals regrowing decreases as the successional stage progresses. The number of individuals resprouting and species composition were significantly different between successional stages. In conclusion, mostly arboreal species in the region of Calakmul, can regrow, which influences the successional development of the forest after slash-and-burn, helping to restore the coverage, structure, as well as species composition original.
