The long-term goals of this project, which is being pursued in collaboration with R. L. Elsberry and M. A. Boothe, are to improve not only the quantitative accuracy of official tropical cyclone (TC) track forecasts, but also the qualitative meteorological utility of those forecasts. Needed improvements in the accuracy of official TC track forecasts include: (i) reducing the severity and frequen...

The tropics, sadly, continues to be a belt of poverty. The countries of the tropics all have low or middling incomes, with a few tiny or natural-resource-rich exceptions, and few of the poorest countries are outside of the tropics. The causes of tropical poverty are surely complex, involving initial endowments (Diamond), history, especially colonization, and geographical isolation (Gallup and S...

Ants are diverse and abundant, especially in tropical ecosystems. They are often cited as the agents of key ecological processes, but their precise contributions compared with other organisms have rarely been quantified. Through the removal of food resources from the forest floor and subsequent transport to nests, ants play an important role in the redistribution of nutrients in rainforests. Th...

Before considering the practical issues involved in implementing such a study, the paper addresses philosophical issues related to the use of contingent valuation including the...

An adequate service life of wooden structures in the sea is ensured only: If wood is treated with biocide wood preservatives with high retention level or; If some tropical hardwoods, with known natural resistance, are used.

The School of Tropical Medicine was founded in 1902 along with the Colonial Hospital of Lisbon. The Portuguese government recognized the importance of colonising the tropics and therefore supported the creation of a specific locus of medical training that would prove to be crucial to the clinical and experimental study of tropical diseases. This paper examines the importance of such institution...

This article discusses to what extent geohazards have shaped both nation’s demogra...
