Diversity of butterfly communities of a tropical rain forest of Bu Gia Map National Park in South Vietnam was studied in four different habitat types (the natural forest, the disturbed forest, the bamboo forest, and the stream sides in the forest) in December 2008 and April 2009. A total of 112 species with 1703 individuals of Papilionoidae (except Lycaenidae) were recorded. The proportion of rare species tends to decrease from the natural forest to the stream sides, while the proportion of common species tends to increase from the natural forest to the stream sides. The stream sides have the greatest individual number, while the disturbed forest contains the greatest species number. The bamboo forest has the least species and individual numbers. The stream side environment in the forest plays an important role in conserving butterfly abundance while the bamboo shows the poorest butterfly diversity.

Land type changes in the super wet tropical rain forest area caused fluctuations in the diversity of soil fauna which caused disruption of ecosystem balance. This research was conducted for four months, in November 2017-February 2018. Data on soil fauna was taken using pitfall traps and hand sorting. Furthermore, the soil fauna data obtained were identified and calculated the value of the diversity index, evenness and dominance on each type of land for four months. The results showed that forests had a high diversity index of soil fauna, which were 3,134, 3,313 and 3,314 in the first to the third month. While in the 4th month the forest diversity index decreased to 2,981. In open land, the soil fauna diversity index value is moderate, which is 2.631, 2.998, 2.782 and the diversity index increases in the fourth month, is 3.084. Mixed gardens have a value of the fauna diversity index of 2,728, 3,113, 2,870 and increased in the fourth month of 3,084. Whereas monoculture gardens have diversity index values of 2,527, 3,214, 2,935 and 2,927. Changes in land types of super wet tropical rainforests have an effect on changes in the level of diversity of soil fauna and not always these changes reduce the level of diversity of soil fauna.

The French Guianan forest is an evergreen rain forest that contains approximately 100 deciduous tree species. The taxonomical distribution of the deciduous character is widely spread, and its presence or absence among some taxa, as well as its ancient origin, are arguments in favour of an endogenous origin. Leaf-fall periodicity was studied on a sample of 500 trees during a 2-year period. Periodicity is annual and seasonal. It is not correlated to rainfall and not linked to the occurrence of a dry season. It seems closely correlated to photoperiodical variations, even though those variations are weak (35 min at latitude 5°30′N). However, each tree has its own periodicity for leaves shedding. Therefore, there is a paradox between seasonality and individual periodicity of leaf fall. The existence of this paradox leads us to consider the hypothesis of an integration of endogenous and exogenous components in the determination of leaf-fall periodicity. Key words: deciduousness, French Guiana, phenology, photoperiodism, tree, tropical rain forest.

For gauging suitability of zygopteran odonates as bioindicators of ecosystems, an attempt was made to record the seasonal diversity of damselflies from seven different types of habitats in Paschim Medinipur District, West Bengal covering 14 land use sites. The study revealed existence of 19 species of damselflies belonging to 10 genera under two families. While the riparian zone had maximum number of species (15), paddy field had the lowest number (six). Ceriagrion coromandelianum and Agriocnemis pygmaea were the most common species. C. coromandelianum was eudominant in grassland and wetland-forest interface, whereas A. pygmaea was eudominant in fish pond and paddy field. Six species, viz., Paracercion calamorum, P. malayanum, Pseudagrion australasiae, P. decorum, P. spencei, and P. microcephalum were confined only to the riparian zone. Maximum abundance of damselflies was found in the riparian zone and minimum in the paddy field. Damselflies exhibited a distinct peak in March–April and a lesser peak in September–October. Most of the land use patterns exhibited similar zygopteran faunal composition. Species diversity index was moderate (1.4–2.5) and evenness index was on the higher side (0.76–0.94). Dominance Index ranged from 26.2 to 64.6. Riparian zone appeared to be the least stressed and most equitable habitat with highest diversity and evenness index and lowest dominance index. Paddy field seemed to be the harshest habitat for damselflies with least diversity and highest dominance index. The present study suggests that community analysis of damselflies can be quite useful in the assessment of the quality of any ecosystem.

Papua is an area with very wide range, from lowland with altitude 0 m to highland area with 4730 m above sea level. Orchids species constitute the greater part of orchids diversity, which can grow on the bare branches of tall trees, or embedded in moss dripping in wet and cool mountain forests, as well as in the eternal shade of tropical rain forest. Numerous plants world-wide are threatened with extinction because of degradation or destruction of their habitat. Orchids are among the most threatened plants of all, especially when pressure from dealers and collectors aggravales the problems. South Papua is a lowland area with the elevation around 0-7 m above sea level, temperature 23-300 C, and 1500 m rainfall per year. The aims of these investigations were to explore the diversity of tropical orchids in South Papua. The exploration and collection were done in Asmat, Boven Digul, Mappi, and Merauke. The study found 22 genera and 75 species, mostly are epiphytic. Key words: orchids, exploration, diversity, South Papua.

Abstract The study about the diversity and structure of treelet vegetation in three slope areas on the mountainous forest of mount Bawakaraeng, Regency of Gowa, Province of South Sulawesi had been done. There were 17 species of treelets throughout the study area, from 13 families and 16 genera. The Asteraceae family has the highest number of species with 3 species, followed by Fabaceae and Solanaceae which each has 2 species. Pteridium aquilinum, Chromolaena odorata, Breynia oblongifolia, and Pogostemon cablin are the species with the highest important value index. The number of treelet species ranges from 15-16. Treelet species were mostly found in the flat slope area. The Shannon-Wiener diversity index (H’) ranges from 2,033-2,161 and was found to be highest on steep slopes and lowest on flat slopes. The H’ has the same tendency as Simpson’s Diversity Index and Evenness Index of Pielou (E) and reverse relationship with Simpson’s Dominance Index.
