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.Wind patterns are strongly shaped by the distance and difference in atmospheric pressure centres (Fig. 2.22B). ... SSTs, in turn, vary with changes in the action of ocean currents affected by winds to form a positive feedback loop. Atmospheric convergence ... Warm ocean currents act as the main engine to hydrostatic instability and increased cloud formation in the ITCZ (Fig. 2.22A), although a high SST does not always lead to large-scale convective activity (Graham and Barnett, 1987).
