The study should help understand differences among species in the tropical dry forest environment. Therefore, we can hypothesize that severe droughts induce leaf shedding and flushing in the tropical rain forest. However, there have been few studies on the environmental triggers of leaf flushing in tropical rain-forest trees under normal conditions of high rainfall. Limits to tree species distributions in lowland tropical rainforest. As such, fog represents a very important hydrological input for this tropical seasonal rain forest. Factors limiting tropical rain forest regeneration in abandoned pasture: seed rain, seed germination, m icroclimate, and soil. Photosynthetic responses to dynamic light under field conditions in six tropical rainforest shrubs occurring along a light gradient. Seedling survival of tropical species: interaction of dispersal distance, light gaps and pathogens. A gradient of seedling growth from the centre of a tropical rain forest canopy gap. Ultimately, long-term field data on tree seedling survival and growth will provide further insights into species regeneration responses during tropical rain forest succession. Quantitative trapping data are newly available that allow a study of abundance relations in tropical communities. Environmental impacts on tropical rainforest dipterocarp tree seedling regeneration. In tropical moist forest, advance regeneration in the form of shade-suppressed seedlings is a major component of regrowth in new gaps. Contrasting leaf phenotypes c ontrol seasonal variation in water loss in a tropical forest shrub. Linking canopy gaps, topographic position, and edaphic variation in a tropical rainforest: implications for species diversity. Do dipterocarp seedlings really partition tropical rainforest gaps? Changes in forest practices will require promotion and acceptance of tropical rain-forest conservation as a priority government policy. Attention has focused almost exclusively on adult beetles, probably because their larvae are conspicuously missing from tropical foliage. How many species of host-specific insects feed on a species of tropical tree? A comparison of species growth rates from four moist tropical forest regions using increment-size ordination. Climatic conditions and tropical montane forest productivity: the fog has not lifted yet. Impact of forest fragmentation on seedling i abundance in a tropical rainforest. Contrasting leaf phenotypes control seasonal variation in water loss in a tropical forest shrub. Factors limiting tropical rain forest regeneration in abandoned pasture: seed rain, seed germination, microclimate, and soil. Increasing day-length induces spring flushing of tropical dry forest trees in the absence of rain. From this and other studies it is clear that habitat heterogeneity is an important factor that allows coexistence of closely related tropical plants. The climate is tropical and strongly influenced by alternating monsoon and dry seasons. The distribution of feeding habits in a tropical rain forest. Effects of climate and stand age on annual tree dynamics in tropical second-growth rain forests. Further investigations are necessary to characterize tropical rain-forest stratification isotopically. Throughfall and stemflow in mature and year-old wet tropical forest. Why are leaf-cutting ants more common in early secondary forests than in old-growth tropical forests? Experimental test in lowland tropical forest shows top-down effects through four trophic levels. Modelling forest growth and yield - applications to mixed tropical forests. The need for efficient sampling is a dominant factor determining methodological decisions, but comparative analysis of efficiency has been lacking in the tropical eco-floristic literature. Factors affecting post-dispersal seed survival in a tropical forest. Ecology of seed and seedling growth for conservation and restoration of tropical dry forest: a review. The response of tropical tree seedlings to nutrient supply: meta-analysis for understanding a changing tropical landscape. Each life form in a tropical montane forest can exhibit respective leaf characteristics reflecting adaptation to the environment. Similar non-random processes maintain diversity in two tropical rainforests. How are stingless bee colonies distributed in tropical wet forests? However, the requirement for a vaccine that would maintain its potency in primitive tropical conditions was acute. His distinguished background in tropical agriculture, both in research and administration, gave him weight in both scientific and government circles. Tropical forests accommodate a wide range of living organisms within the ecosystem. Empirical results presented here focus on the factors affecting depletion of natural tropical forests. Although recalcitrant seeds are common in mesic tropical forests, they are by no means confined to these systems. Radial growth, measured as tree-ring widths, averaged between 2 and 4 mm y-1 which is comparable to fast growing tropical species in mature forests. Assessing the response of plant functional types to climatic change in tropical forests. How to sample the epiphytic diversity of tropical rain forests. In tropical moist forests, length of the dry period may have a profound influence on leaf dynamics, plant growth and survival. In addition, diversity of tropical forests often restricts the repeatability of observations of specific plant-insect interactions. Due to logistic constraints with telemetry of small passerines in tropical rain forests, our sample sizes remained limited. Correlations between plant growth and nutrient availability have often been observed in tropical montane forests. A test of nutrient limitation in two tropical montane forests using ingrowth cores. Net primary production in tropical forests: an evaluation and synthesis of existing field data. Arthropods of tropical forests are one of the critical groups, due to their abundance and diversity. Understanding the dynamic structure of tropical forests is of interest in several ecological and evolutionary contexts. As tropical deforestation continues, young secondary forests assume increasing importance as a reservoir of biodiversity. Rehabilitation of tropical lands: a key to sustaining development. A major question is whether local societies in tropical regions should be considered as agents of deforestation or as creators of dynamic forested landscapes. Due to human land-use in many areas, the type of disturbance characterizing tropical forest landscapes is more intense now than it has been for millennia. Will tropical forests also be overwhelmed by exotic species, or do tropical forests possess some resistance against invasive species? The book is a beautifully written, well indexed and authoritative work of reference on tropical rain forest ecology primarily from the botanical viewpoint. Many academic scientists control discretionary resources and, in some cases, tropical disease grants. His passion for tropical fish led him to the humble zebrafish. There is a technique of memory that holds out an at best uncertain relationship to any tropical regulation or form. Area fees have become an increasingly important component of forest revenue systems in tropical developing countries. In addition, the 'wealth effect' of transfers counteracts the 'freeing-up effect', which implies that per unit of subsidy fewer hectares of tropical forest are protected. The picture it draws is then used as a guide to practical policy proposals for tropical forest management. They live in and near tropical forests and are for the most part poor. A dynamic model of selective harvesting in multi-species, multi-age tropical forests is developed. High prices and demand for tropical agricultural commodities can stimulate the clearing of forests to produce these commodities. The positive contribution of tropical rainforest conservation to climate regulation is also a significant benefit and this will be dealt with in detail first. The conservation significance of small-scale eco-forestry, therefore, is that groups ostensibly set aside 1,000 hectares of tropical lowland rainforest for the next 50 years. The model has shown that global benefits dominate in economic modelling of tropical forest conservation. There is still a great deal to be learned about climate sensitivity, especially in the tropical regions of the world. All three protected areas are composed mostly of tropical lowland forest, and are well-known for their diversity of forest birds. These examples are from corpora and from sources on the web.
