“…Em programas silviculturais, o controle de lianas tem sido recomendado como ferramenta de manejo florestal (Engel et al 1998). Porém, quando o enfoque é a conservação de fragmentos florestais e não a produção de madeira, os possíveis impactos ecológicos decorrentes da eliminação das lianas não são conhecidos (Johns 1988). Devido à escassez de conhecimento de sua biologia e a sua importância nos fragmentos florestais, muitas questões sobre o manejo e a conservação de florestas ainda estão sem respostas.…”

-(Lianas of a seasonal semideciduous forest, Paulo de Faria, northern São Paulo State, Brazil). Lianas are soilgerminating plants, perennially rooted that need support to reach the canopy. In tropical forest they are an important form of life due to their diversity, they are part of the forest structure, and source of food for various animals species. The aim of this study was to evaluate the species composition, the diversity and the structure of a liana community in a seasonal semideciduous forest at the Ecological Station of Paulo de Faria, São Paulo, Brazil. The sampling included lianas specimens with DBH ³ 1 cm collected in 100 plots of 10 x 10 m (1 ha). We collected 1,427 individuals representing 45 species. The species diversity (H') was 2.98 nats individual -1 . The richest families were Bignoniaceae (14 species), Sapindaceae (nine), Malpighiaceae (six) and Leguminosae (four), similarly to other neotropical forests. The families Bignoniaceae, Sapindaceae and Apocynaceae were represented by a great number of individuals, Melloa quadrivalvis (Bignoniaceae) was the most important species. The majority of the sampled individuals (57.6%) had diameters between 1-2.5 cm and in 26 individuals only the diameter was larger than 10 cm. If the purpose of a study of a liana community is to estimate the abundance our data suggest that all individuals with DBH > 1 cm must be sampled.

“…This might be that an open areas may provide suitable habitat and foraging sites for them (Gram et al, 2003;Campbell et al, 2007). Selective forest logging leads to the increase of temperature and decrease relative humidity (Johns, 1988;Jackson et al, 2002). Opening gaps enhance shrub vegetation which frequently bears diverse flowers and fruits which is a major diet of these bird species.…”

Logging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. We compared the avian richness and diversity in different aged post-harvested hill dipterocarp tropical rainforest at the Berkelah Hill Dipterocarp Rainforest Reserve in Maran, Pahang, West Malaysia using mist-netting method. We captured a total of 1908 individuals representing 86 species and 29 families (i.e., 18.55% from two years postharvested forest, 25.10% from ten years post-harvested, 23.90% from twenty years post-harvested and 32.44% from thirty five years post-harvested forests). Forty nine species were caught in two years and ten years, 55 species in twenty years and 59 species in thirty five years' post-harvested forest. Seventeen species were common in all four types of forest. Pycnonotidae, Timaliidae and Nectariniidae were the most dominant families in all types of post-harvested hill dipterocarp tropical rainforest. Diversity analysis indicated that the bird species in twenty years post-harvested hill dipterocarp rainforest was most diverse (i.e., Fisher's Alpha Diversity Index; 16.34) and evenly distributed (i.e., McIntosh Evenness index E; 0.933) as compared to two years, ten years and thirty five years post-harvested forest. However, thirty five years post-harvested forest was richest in avian species (i.e., Margalef's Richness index R 1 ; 9.02) as compared to other post-harvested forest. The findings of this study revealed that logging and recovery process may affects on avian distribution and diversity. However, these effects may vary from species to species.

ISBN 979-3361-56-5The Center for International Forestry Research (CIFOR) was established in 1993 as part of the Consultative Group on International Agricultural Research (CGIAR) in response to global concerns about the social, environmental and economic consequences of forest loss and degradation. CIFOR research produces knowledge and methods to improve the well-being of forest-dependent people and to help countries manage their forests wisely for sustainable benefi ts. This research is conducted in more than two dozen countries, in collaboration with numerous partners. Since it was founded, CIFOR has also played a central role in infl uencing global and national forestry policies.
