“…Thus, each successional forest is a unique plant community. Species composition appears to vary independently of species richness in the succession and is strongly determined by differences in land use and the colonizing vegetation (Finegan 1996;Chazdon 2003). The three successional forests had similar histories and were embedded in a relatively forested landscape, which potentially allowed for the same possibilities of seed arrival in the three abandoned areas (unpublished data).…”

“…In addition, it is possible that plant colonization after the abandonment of the area had been affected by the regional landscape that had changed over the 60 years. The 10-30-year-old (phase 2) forest is believed to contrast with the 30-100-year-old (phases 3 and 4) forest in species composition because short-lived pioneers are replaced by longlived pioneer and non-pioneer species (Finegan 1996). However, our results indicate that species turnover might be more complex than previously suggested and that, even after a long time (59 years), species (shade-tolerant or intolerant) are still being replaced.…”

“…Tropical forest succession is characterized by changes in species composition, from herbs, shrubs, vines and fast-growing pioneer tree species during the first 30 years, to long-lived pioneer trees and shade-tolerant species during the following 70-120 years (Finegan 1996). According to the initial floristic composition hypothesis (Finegan 1996;Uhl et al 1998;Guariguata & Ostertag 2001;Peñ a-Claros 2003), species representing all guilds colonize soon after disturbance but reach dominance at different times according to their growth rates and longevities (Egler 1954). Our results support this hypothesis and also agree with the consensus that species composition in forest succession is highly unpredictable (Chazdon 2008).…”

“…Future global land cover scenarios include forests that have resulted from multiple successional pathways (Corlett 1995). For decades, studies have focused on factors that have influenced the structure and diversity of secondary tropical forests (Denslow 1980;Brown & Lugo 1990;Finegan 1996;Guariguata & Ostertag 2001;Chazdon 2008). However, the successional trajectories of these forests still remain uncertain.…”

MARQUES, C.M.M., ZWIENER, V.P., RAMOS, F.M., BORGO, M., MARQUES, R. Forest structure and species composition along a successional gradient of Lowland Atlantic Forest in Southern Brazil. Biota http://dx.doi.org/10.1590/1676-06032014009414Abstract: The Lowland Forest is one of the most disturbed and fragile ecosystems in the Atlantic Forest biome, yet little is known regarding its successional trajectory and resilience. We evaluated changes in species assemblages and forest structure of the canopy and understory along a successional gradient (young 21-yrs old forest, immature 34-yrs old forest and late successional 59-yrs old forest) aiming to assess changes in species composition and successional trajectory of different strata of secondary forests. A 0.1 ha plot (ten 10x10 m sub-plots) from each forest stand was surveyed for trees and shrubs with a diameter at breast height (DBH) > 4.8 cm (canopy) and for individuals with heights > 1 m and DBH , 4.8 cm (understory). A total of 3,619 individuals from 82 plant species were sampled. The successional gradient was marked by a unidirectional increase in species richness and a bidirectional pattern of density changes (increasing from young to immature forest and decreasing from immature to late successional forest). Community assemblages were distinct in the three forests and two strata; indicator species were only weakly shared among stands. Thus, each successional forest and stratum was observed to be a unique plant community. Our results suggest slight predictability of community assemblages in secondary forests, but a relatively fast recovery of forest structure.

“…Ce sont des essences dont la plupart sont de tempérament héliophile, se reproduisant de préférence dans les chablis, et les formes lianescentes évoluent au niveau de la canopée du dôme forestier. Leur nombre relativement élevé témoigne de la dimension assez large de la trouée au sein de la canopée et ayant engendré leur installation en vue d'initier une succession secondaire (Finegan, 1996).…”

Natural and anthropogenic disturbances affect forest integrity and floristic composition. The resulting secondary habitats is characterised by liana and herb species which modified the forest physiognomy. To elucidate the floristic characteristics of these secondary forests, the present study was carried out after logging operations in the the Haut-Sassandra protected Forest. The inventory has been realised in 18 individual one ha in three level of logging operation. A total of 445 species have been identified. Floristics parameters vary according to the time after logging operation: from 255 in the south sector, 296 species in the center sector, 271 species in the north sector, 15 years after logging. The family diversity is between 56 and 62 with a predominance of Rubiaceae. Phytogeographic-types are characterized by Guinean-Congolese species (71,2 %), and species endemic to SavannahForest transition zone (14,6 %). The presence of herb and liana species which are pioneer and heliophile, could generate a micro climate favorable to the recovery of other forest plant species.Keywords: Forest resilience, forest logging, ecological temperament, floristic gradient, Côte d'Ivoire RésuméDes perturbations tant naturelles qu'anthropiques, affectent l'intégrité des forêts et leur composition floristique.

Les résultats montrent une variation des paramètres floristiques en fonction du secteur d'exploitation: 255 espèces dans le secteur Sud, 296 espèces dans le secteur Centre, 271 espèces dans le secteur Nord, 15 ans après les exploitations. La diversité des familles est comprise entre 56 et 62 avec une prédominance des Rubiaceae. Les types phytogéographiques sont caractérisés par des espèces à distribution Guinéo-Congolaise (71,2 %) et des espèces de la zone de transition Savane-forêt (14,6 %). La présence de cette flore herbacée et lianescente, souvent pionnière et héliophile, génère un microclimat qui pourrait être favorable à la germination d'autres semences forestières.

A flash in the pan? The population dynamics of a dominant pioneer species in tropical dry forest succession

Globally, around half of all tropical forests are secondary communities which are recovering from previous disturbances. In these communities, dominant pioneers play a critical role in the successional dynamics due their ability to modify the environment, and thus to facilitate or hinder the performance of other species. In this study, we examined the population dynamics of the dominant pioneer species, Mimosa acantholoba var. eurycarpa, in a tropical dry forest during the process of secondary succession. We collected data from permanent plots over a period of 13 years and used integral projection models to analyze the vital rates and changes in population size. Most vital rates were negatively related to successional age, with resprouting, survival and recruitment of individuals responding more strongly, and individual growth rate more weakly. These vital‐rate trends translated into significant variation of population size over succession, with a maximum size at year four and a rapid decline thereafter. Overall, our findings suggest that this species benefits from its ability to display a large number of resprouts in very early stages of succession, contributing to the rapid increase in population density. However, as succession unfolds, a lack of resprouting and a decline in survival reduce its population size, to the point of local extinction. These results highlight the importance of resprouting in the early dynamics of tropical dry forest communities recovering from disturbance.
