Tree density, basal area and species diversity in a disturbed dry tropicalforest of northern India: implications for conservationBackgroundDry tropical forest communities are among the world’s most threatened systems. Rapid measures are required to protect and restore them in degraded landscapes. For planning conservation strategies, there is a need to determine the essential measurable properties, such as number of species and basal area, that best describe the dry forest vegetation and its environment, and to document quantitative relationships among them.

Cobertura De Copas Como Indicador De Desenvolvimento Estrutural De Reflorestamentos De Restauração De Matas Ciliares No Médio Vale Do Paranapanema, SP, BrasilThis study analyzed crown cover in riparian forests 1 to 3 years after reforestation in the Médio Vale do Rio Paranapanema, São Paulo, Brazil to evaluate the technique as a means to monitor the progress of restoration. Using a line inspection technique, crown cover significantly correlated with age, height, basal area, and DBH. The authors concluded that this is a suitable technique for planted riparian forests up to 3 years in age to evaluate changes in forest structure, and suggest that models might be developed to predict crown cover based on age and site variability.

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 |
