Ecohydrology research projects undertaken, within the framework of the International Hydrological Programme, in Latin America and the Caribbean are presented, together with contact details of the participants. These include investigations by national research organizations in Argentina, Bolivia and Brazil, as well as collaborative projects involving Brazilian researchers and colleagues from Germany, France, Canada and USA. Details of other German, French and USA projects undertaken in the region are also given. The regional co-ordination of ecohydrology projects, undertaken by the author in co-operation with a working group with members from Argentina, Cuba,. Guatemala, Guyana and Paraguay has involved participation in international meetings, contributions to conference proceedings and involvement of research workers from Latin America in a UNESCO IHP V advanced study course in ecohydrology. Budget constraints and other factors limited or precluded research institutes in several countries in the region from participating more fully in the 1996-2001 programme. However, it is hoped that a more comprehensive and better integrated series of ecohydrological research projects will be undertaken during phase 2. It is anticipated that this will lead to a deeper knowledge of the aquatic ecosystems of the Latin America / Caribbean region and to sustainable development of its natural resources through application of ecohydrological principles.

Basicladia chelonum (Collins) W.E. Hoffmann and Tilden (1930) principally known from North America and Hawaii was recently (2004) found in Cuba (Caribbean) from artificial pool growing on shells of musk turtles (Trachemys decussata Gray). Specimens collected in Cuba were subjected to detailed examinations also using a transmission electron microscope. On one hand, these studies confirmed many features of this species previously described by earlier authors in the specimens from Texas. On the other hand, the present studies revealed structures unknown so far (pyrenoid structure), which allowed for new analysis of this species. These investigations also have shown that Basicladia chelonum exhibits close similarity to the genus Cladophora and other representatives of the class Cladophorophyceae. The similarities include : siphonocladous level of organization of thallus, numerous chloroplasts forming a network and other structures. Conversely, the pyrenoid in vegetative cells of Basicladia chelonum distinguishes it markedly from representatives of the genus Cladophora, which have bilenticular pyrenoids divided into two hemispheres by a single thylakoids and each hemisphere is covered by a bowlshaped starch grain (Van Hoek et al. 1995). Since in Cladophora the ultrastructure of the pyrenoid is highly constant and characteristic, this contrasts with the genus Basicladia and, therefore, more firmly establishes position of the latter as an independent unit within Cladophorophyceae.

Data presented herein provide records of four species of bats new to the fauna of the Antillean island of Saba — Monophyllus plethodon, Ardops nichollsi, Tadarida brasiliensis, and Molossus molossus. Together with three species previously recorded from the island – Brachyphylla cavernarum, Artibeus jamaicensis, and Natalus stramineus – the chiropteran fauna of the island is documented to be composed of seven species. Our analysis of species/area relationships for West Indian bats provides a slope value of z = 0.177 and R2 = 0.76; therefore, the bat fauna of the West Indies has the flattest slope for this relationship of any West Indian group. This relationship is best explained by a propensity for over water dispersal by West Indian bats. We propose to unite the chiropteran faunas of the islands of Anguilla, Antigua, Barbuda, Nevis, Saba, St. Barthélemy, St. Eustatius, St. Kitts, and St. Martin by recognizing them as the Northern Antillean Faunal Area. Given the small size of Saba (12 km2) and the even smaller effective habitat for non-molossid bats (4 km2), conservation concerns are expressed for the future of the fauna and some recommendations are made for its preservation.
