The commonly observed high diversity of trees in tropical rain forests and corals on tropical reefs is a nonequilibrium state which, if not disturbed further, will progress toward a low-diversity equilibrium community. This may not happen if gradual changes in climate favor different species. If equilibrium is reached, a lesser degree of diversity may be sustained by niche diversification or by a compensatory mortality that favors inferior competitors. However, tropical forests and reefs are… 

The community ecology of Asian rain forests, in relation to catastrophic events

Although natural catastrophic disturbance of tropical forests in Asia can be caused by volcanism and earthquakes climate-induced catastrophes are most widespread. These are prevalent and most diverse

Patterns of Tree Species Diversity Among Tropical Rain Forests

In this early report of a global program of tropical rain forest research, the causes of tree species diversity are examined through comparisons at global, regional and local scales. Species

Dynamics of Wet Tropical Forests and Their Species Strategies

The physiological ecology of tropical vegetation in general and that of the rainforest in particular is poorly understood. Several factors have contributed to this situation, among which are the

Tree Diversity in Tropical Rain Forests: A Validation of the Intermediate Disturbance Hypothesis

This hypothesis was tested on a sample of 17,000 trees in a Guianan forest, 10 years after a silvicultural experiment that added to natural treefall gaps a wide range of disturbance intensities.

Species Diversity in Tropical Vertebrates: An Ecosystem Perspective

The understanding of the ways in which species-rich communities are structured and maintain themselves does not forcibly tell us why such assemblages are the rule in the humid tropics but not elsewhere; some further considerations on this subject might therefore be timely.

Drivers of lowland rain forest community assembly, species diversity and forest structure on islands in the tropical South Pacific

1. Testing the comparative strength and influence of age and area of islands, proximity of source propagules and disturbances on community assembly, species diversity and vegetation structure has

Maintenance of forest species diversity and latitudinal gradient

The species diversity of trees maintained in tropical rain forests is much higher than in temperate, boreal, or seasonally dry tropical forests. Many hypotheses have been proposed for higher

Long-term impacts of logging on forest diversity in Madagascar.

This work investigated the impacts of logging 50 and 150 years ago on tropical forest vegetation in Madagascar, a "hotspot" of biodiversity, and found logging was the overriding factor influencing establishment of nonnative plants.

Biodiversity and the functioning of tropical forests

Tropical forests are the most diverse terrestrial ecosystems. Moreover, their capacity for removal of carbon from the atmosphere makes them important for climate change mitigation. Theories predict

Maintenance of High Diversity in Coral Reef Fish Communities

The argument is developed that reef fishes are adapted to this unpredictable supply of space in ways which make interspecific competition for space a lottery in which no species can consistently win.

The tropical rain forest: a nonrenewable resource.

Either voices of these voices have not been heard or their arguments have not be convincing enough to promote action in this direction.

Community Structure of Coral Reefs on Opposite Sides of the Isthmus of Panama

There is an inverse relation between coral abundance and diversity, except in areas where distrubances, such as Acanthaster predation offset space monopolization.

Some Physical and Biological Determinants of Coral Community Structure in the Eastern Pacific

Various physical and biological factors affecting coral community structure were investigated by direct observation and periodic censusing on three coral reefs off the Pacific coast of Panama from 1970 to 1975, finding that competition, predation, bioturbation, and mutualism assume an increasing influence on community structure in deeper and more diverse reef assemblages.

Herbivores and the Number of Tree Species in Tropical Forests

Any event that increases the efficiency of the predators at eating seeds and seedlings of a given tree species may lead to a reduction in population density of the adults of that species and/or to increased distance between new adults and their parents.

Evidence suggests that alleochemical provide a wide-spread, specific, and complex mechanism for interference competition for space among natural populations of coral reef organisms.

Catastrophic Damage to Coral Reef Communities by Earthquake

THERE is interest in the disruption of coral reef communities by isolated events such as hurricanes, river floods, and torrential rainfall over reef areas1,2 or by seasonal fluctuations of sea level,


One of the differences between man-made polluting activities and natural catastrophes on coral reefs, is the possibility that the human- perturbed environment will not return to its former configuration, while reconstitution of reef areas denuded by natural disturbances is mainly a function of time.
