OCEANOGRAPHIC PROCESSES OF CORAL REEFS: Physical and Biological Links in the Great Barrier Reef - Chapter 11

Các khái niệm về cảnh quan quy mô "kết nối" hệ sinh thái không phải là mới và cũng không một toàn bộ khoa học xây dựng. Úc nhà thơ Judith Wright tổng kết những gì nhiều nhà khoa học trực giác cảm nhận về rạn san hô khi cô đã viết: Các nhà sinh học hiện nay thường nói về rạn san hô là hệ thống chỉ chính của một hệ thống tổng thể của rạn san hô trong suốt toàn bộ khu vực Indo-Thái Bình Dương, và nghi ngờ rằng có thể được kết nối của tất cả các rạn san hô thông. | 11 Connectivity in the Great Barrier Reef World Heritage Area An Overview of Pathways and Processes Mike Cappo and Russell Kelley CONTENTS Introduction.161 The Great Barrier Reef in Time and Space.162 A Walk around the Great Barrier Reef World Heritage Area.163 The Cross-Shelf Paradigm and Land-Ocean Processes How Far Offshore Does Land Influence Extend .168 Cross-Shelf and Inter-Oceanic Connectivity through Food Chain Links.170 Connectivity amongst Habitats through Larval Dispersal and Ontogenetic Migration.173 A Case Study of Baitfish-Predator Links.175 Conclusion.177 Acknowledgments.177 References.177 INTRODUCTION The notion of landscape-scale ecosystem connectivity is neither new nor a wholly scientific construct. Australian poet Judith Wright summed up what many scientists intuitively feel about reefs when she wrote Biologists now often talk of the Reef as only the main system of an overall system of reefs throughout the whole Indo-Pacific region and suspect that there may be interconnection of all these reefs through the planktonic movement across the ocean. The Reef cannot be thought of either as separate from the mainland coasts with their many fringes of great mangrove forests that form a tremendously fertile breeding-ground for 161 2001 by CRC Press LLC 162 Oceanographic Processes of Coral Reefs many species which during part of their lives may enter the waters of the reef proper. The interlocking and interdependent physical factors which have so long kept the reef alive and growing such as water temperatures freshwater replenishment from streams and estuaries the tidal movements which bring deep ocean water in and out of the calmer and narrower waters within the Barrier and the winds and weather systems are probably all indispensable to the maintenance and dynamics of its living species.
