This volume reports on the findings of experts on tropical zooplankton gathered at a meeting in Kariba, Zimbabwe, in 1991. Some basic questions were asked on community composition and biodiversity in the tropics versus the non-tropics. Old ideas on the nature of zooplankton, which were found to be wider than the `classical' rotifers, cladocerans and copepods, as well as on the number of species in tropical waters, are now beginning to break down accordingly as more and more blank spots in the tropics are explored and as more in-depth studies on the zooplankton of tropical lakes are becoming available. This volume contains a mix of papers discussing the two alternative controls (bottom-up and top-down) of zooplankton community structure and these constitute another step towards a coherent theory of tropical ecosystem theory.

Freshwater is a most precious natural resource. To the developed world, refreshing, untainted water is presumed from the taps of millions of householders. The many rivers, streams, ponds and lakes are for the pleasure and enjoyment of the leisure hours of urban dweller and rural inhabitant alike-boating, fishing, sailing and swimming come readily to mind. To the agriculturalist and industrialist it is often the cornerstone of their enterprises. To the environmentalist and naturalist it is the basis of the wetland and open water communities which provide the habitats for a wealth of flora and fauna. In the developing world the emphasis is very different. A spring, well, river or swamp is the basis of day-to-day survival for family, livestock and crops. Subsistence fishing is often the major source of protein. Freshwater may be the unwitting purveyor of disease but with good management this can be regulated and monitored. But Man by nature, is a selfish species who tends to have scant regard for the quality of life of future generations. The much publicised destruction of forests is a notorious example. Not so well-known is the pressure on one of the world's most fragile ecosystems, the wetlands.

Reprint of the 1958 ed. published by France-Empire, Paris.

This handbook is an annotated answer key to C.L. Seow's widely used "A Grammar for Biblical Hebrew (Revised Edition). For each exercise in that grammar, this key refreshes the student on lessons already learned, reinforces explanations and terms used in the lesson, explains concepts not yet covered, and cites relevant information in the standard dictionaries and reference grammars (for example, Jouon, BDB, Waitke-O'Connor). This companion volume allows students to make the most of the introductory grammar (in course and self-guided study). The reference to the major research grammars and lexicons will enable both student and instructor to take it to the next level, so to speak, in studying and translating biblical Hebrew, and give the instructor increased flexibility in classroom curriculum.

Through close analysis of several major novels of the past decade, including works by Don DeLillo, Philip Roth, Kathryn Davis, Jonathan Franzen and Richard Powers, Late Postmodernism examines the forces shaping contemporary literature and the remarkable strategies American writers have adopted to make sense of their place in culture.
