True rainforests are typically found between 10 degrees north and south of the equator see map ; they are a sub-set of the tropical forest biome that occurs roughly within the degree latitudes in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn. Within the World Wildlife Fund 's biome classification, tropical rainforests are a type of tropical moist broadleaf forest or tropical wet forest that also includes the more extensive seasonal tropical forests.

Ghazoul, J. Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities.

Tropical Rain Forest Ecology, Diversity, and Conservation

This paper reviews the various factors that facilitate the high biodiversity of soil communities, concentrating on soil animals. It considers the problems facing soil ecologists in the study of soil communities and identifies the important role such communities play in terrestrial ecosystems. The review also considers diversity and abundance patterns. A range of factors are identified that may contribute to the biodiversity of soil and their role is reviewed. These include diversity of food resources and trophic specialization, habitat favourableness, habitat heterogeneity in space and time, scale and spatial extent of the habitat, niche dynamics and resource partitioning, productivity, disturbance and aggregation. The role of aggregation and how it relates to the spatial scale under consideration and to species interactions amongst soil animals is largely unknown at present. The role of disturbance is equivocal and man's activities more often than not seem to lead to a reduced biodiversity of soil communities.

They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain despite decades of conservation attention increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics.

One of the main environmental threats in the tropics is selective logging, which has degraded large areas of forest. In southeast Asia, enrichment planting with seedlings of the dominant group of dipterocarp tree species aims to accelerate restoration of forest structure and functioning. To test for potential insurance effects, we analyse the patterns of seedling mortality and growth in monoculture and mixture plots over the first decade of the Sabah biodiversity experiment. Our results reveal the species differences required for potential insurance effects including a trade-off in which species with denser wood have lower growth rates but higher survival. This trade-off was consistent over time during the first decade, but growth and mortality varied spatially across our ha experiment with species responding to changing conditions in different ways. Overall, average survival rates were extreme in monocultures than mixtures consistent with a potential insurance effect in which monocultures of poorly surviving species risk recruitment failure, whereas monocultures of species with high survival have rates of self-thinning that are potentially wasteful when seedling stocks are limited. Longer-term monitoring as species interactions strengthen will be needed to more comprehensively test to what degree mixtures of species spread risk and use limited seedling stocks more efficiently to increase diversity and restore ecosystem structure and functioning.

Economics and Ecology pp Cite as. Biodiversity, or biological diversity, is the number, variety and variability of living organisms. It is used today both as a loose description to embrace the richness and variation of the living world and politically within the context of economics and development for the purposes of national and international conventions and agreements. It has three related components at different levels of organization: genes, species and ecosystems. Species diversity is commonly considered the measure of biodiversity: 1. However such estimates, and the numbers of species already identified, depend on how they were described as distinct by taxonomists and systematists — ecologically, morphologically, physiologically, genetically, mathematically?
