Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal TechniquesbackgroundThis study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species. Open access copy available |
Regeneration Pattern and Size-Class Distribution of Indigenous Woody Species in Exotic Plantation in Pugu Forest Reserve, TanzaniabackgroundThis study examines the natural regeneration of indigenous tree species in an exotic tree plantation adjacent to a natural forest in a coastal forest of Tanzania. Research Goals & MethodsFour dominant indigenous tree species were identified in the exotic plantation with diameter size classes between 10 to 35cm. Open access copy available |
Caracterização do Dossel e do Estrato de Regeneração Natural no Sub-Bosque e em Clareiras de Uma Florestal Estacional Semidecidual no Município de Viçosa, MGThe authors analyzed clearings in a forest reserve belonging to the Federal University of Viçosa, MG, to compare the species and composition of clearing and forest understory vegetation. The found that the level of diversity (Shannon index) and species found (n= 69) were similar in the clearings and the understory in the surrounding forest. Coffee (Coffea arabica) and Picramnia regnellii were the most common species in both the clearings and the understory. The authors suggest that the dominance of coffee may be problematic for the regeneration of native species. Open access copy available |
Banco de Sementes como Indicador de Restauração de uma Área Degradada por Mineração de Caulim em Brás Pires, MGThe authors germinated the seed bank from degraded former kaolin mining sites that have regenerated naturally for a period of 20 years. They used two light treatments usedfor the germination: one with 11.5% shade, and another with 60%. There was a wide range of variation among the species according to the light level, with some species producing far more seedlings under one treatment that the other. Most (2/3) of the species germinating (total n: 36) were herbaceous, with eight tree species (see above). Open access copy available |

Impacto humano afeta negativamente a dispersão de sementes de frutos ornitocóricos: uma perspectiva global (Human impact affects negatively the seed dispersal in ornithochorous fruits: a global perspective)This literature-based analysis used data from a number of existing studies of seed dispersal by birds to compare the effects of plant characteristics and human impact on bird choice and seed dispersal. The study found that plant morphological characteristics did not effect on the frequency of bird visits or fruit consumption. However, the human impact on each site did have a significant effect. Areas with high human pressure had more than 3 times fewer visits and fruit consumed by birds. These data may be important for restoration efforts in gauging the intensity of seed rain for tree species dispersed by birds. Open access copy available |
