Tropical Forests of the Guiana Shield: Ancient Forests in a Modern World
The Guiana Shield is an ancient geological formation located in the northern part of South America, covering an area of one million square kilometres. Despite its hostile environment, it is home to many unusual and highly specialized plants and animals, which constitute a rich area of biodiversity. Chapters in this book include hydrology, nutrient cycling, forest phenology, insect-plant interactions, forest microclimate, plant distributions, forest dynamics and conservation and management of flora and fauna. It provides a comprehensive and detailed review of the ecology, biology and natural history of the forests of the area.

Page 68 - It is never either spring, summer, or autumn, but each day is a combination of all three. With the day and night always of equal length, the atmospheric disturbances of each day neutralising themselves before each succeeding morn; with the sun in its course proceeding mid-way across the sky, and the daily temperature the same within two or three degrees throughout the year— how grand in its perfect equilibrium and simplicity is the march of Nature under the equator!

Page 68 - A little difference exists between the dry and wet seasons ; but generally, the dry season, which lasts from July to December, is varied with showers, and the wet, from January to June, with sunny days. It results from this, that the periodical phenomena of plants and animals do not take place at about the same time in all species, or in the individuals of any given species, as they do in temperate countries.

Our evenings were generally fully employed preserving our collections, and making notes.

Page 462 - Aborigines number on the schedules 7,463 or 3,917 male and 3,546 females. To the total population this is 4 per cent. The Registrar-General gives 10,000 more of this race as estimated to be wandering about the interior of the colony. The number on the schedule shows a decrease on the figures of 1881, when 7,762 were returned. This race is of little or no social value and their early extinction must be looked upon as inevitable in spite of the sentimental regret of Missionaries. At the same time it...
