    Includes bibliographical references and index.This publication presents the results of the collaborative research, commencing with a report on the collection of a broad range of genetic material of fodder potential in Belize, the Yucatan and Guatemala, the initial evaluation of some of this material in Belize and a brief review of the impact of the collection on forage development over the past 30 years (Chapter 2); in fact this germplasm collection stimulated much of the work reported in this volume. An analysis of the value and potential of Stylosanthes genetic material adapted to heavy clay soils follows. This study mainly focuses on S. hamata and its relatives, and is based in part on collections made concurrently in the Caribbean islands and South America as part of the collaborative programme (Chapter 3). The Belize collections of Desmanthus species stimulated interest in the genus and based on those collections and others made later by other collectors, studies were undertaken on the potential of the genus generally, and specifically for its potential for development for heavy clay soils (Chapters 4 and 5). Chapters 6 through 9 report on the steps undertaken to select and test germplasm for adaptation for the heavy clay soils of the dry Australian tropics and subtropics where Desmanthus species were the most successful of those tested. The variation within the genus as related to its distribution and its adaptation to Australian environments is discussed. Chapter 10 provides recent advances in the development of forages for heavy clay soils in Australia. The final series of chapters (11 through 19) describes the Belizean environments for which forage germplasm was being selected and the testing of the regionally collected legume accessions for their adaptation to, and suitability for, pastures on clay soils in a range of environments compared to exotic material.Providing Pasture and Ley Legumes for Use on Clay Soils in Tropical and Subtropical Environments / R.L.

    An investigation of thermal structure in two fresh-water lakes

    No full text
    The temperature fine structure of the thermocline in two stratified fresh water lakes is investigated using data from repeated vertical temperature profiles, and temperature time series from moored thermistor chains. The data show that much of the structure in the thermocline migrates through the water column with time. Analysis suggests that the migrating aspect of the structure is associated with the natural oscillations of the lake.A theory for the wind forced internal oscillations of a viscous, non-rotating, long-narrow lake of constant stratification is developed. The introduction of viscosity gives a smooth phase change with depth near the nodes of the vertical displacement profile, and enables the theory to model the observed vertical migration of features in the lake.The theory is compared to several aspects of the data from the two lakes. Phase profiles calculated from thermistor chain data are compared to the predicted phase profiles, and in the. diurnal frequency band where the wind forcing is strongest the agreement is good for values of the viscosity of about 0.1 cm2 sec 1. The amplitude of the vertical displacement, in the diurnal frequency band, agree best with values predicted by the theory for a viscosity of 0.2 cm2 sec 1, which, considering the errors involved, is not significantly different from the value obtained from the phase profiles. Comparisons are also made between the theory and observations of the energy as a function of the' forcing in various frequency bands, of the phase profiles as a function of frequency, and of the phase of the wind relative to the internal oscillations. The agreement in all cases is sufficient to warrant the description of the migrating structures in terms of damped internal oscillations of the lake.</p
