USP’s Visiting Adjunct Professor, Dr Ravindra. C. Dr Joshi, recently co-edited a second book on Invasive Apple Snails, published by the Philippine Rice Research Institute (PhilRice). The book was edited by Dr Joshi, Dr Robert H. Cowie and Dr Leocadio S. Sebastian.
A Visiting Adjunct Professor at The University of the South Pacific (USP), Dr Ravindra Chandra Joshi recently edited a second book on Invasive Apple Snails, published by the Philippine Rice Research Institute (PhilRice).
In the book’s foreword, Dr Daniel Simberloff of the University of Tenesse, said Biology and Management of Invasive Apple Snails serves not only as an authoritative source for those trying to understand Pomacea impacts, how to manage them, and how to prevent further introductions, but as a model for invasion as scientists begin to comprehend and grapple with the complexity of many of the most important invasions by all kinds of animals and plants.
He noted that the book highlights how important good basic science is to slowing the wave of invasions transforming the ecology of the earth.
“I hope this book, published by the Philippine Rice Research Institute (PhilRice), will be widely used by researchers, extension workers, museum scientists, policy makers, consumers, and farmers, so that the threat of invasive apple snails will become part of history,” he noted.
The book was edited by Dr Joshi, Dr Robert H. Cowie and Dr Leocadio S. Sebastian.
In 2000, one species of apple snail, Pomacea canaliculata, was listed among the world’s 100 most invasive species, largely because it had become a major pest of wetland rice in much of Southeast Asia.
However, this listing was published at a time when there was still confusion regarding the true identity of the invasive species in Asia; in fact two species involved, not only Pomacea canaliculata but also Pomacea maculata. Pomacea canaliculata is native to Argentina and Uruguay, while P. maculata is more widely distributed from the La Plata region of Argentina to the Amazon basin of Brasil, including Uruguay and Paraguay, and possibly Bolivia, Ecuador and Peru.
These two species have commonly been referred to as golden apple snails, or GAS, often without clarifying specifically which species, perhaps both, was involved, or indeed simply assuming it to be Pomacea canaliculata. For clarity, the book avoids this ambiguous common name designation, and hopes that others will move forward with the correct species designation for the apple snails with which they work. Only in this way can research results be truly comparative and useful.
Extensive applied research was undertaken during the first two decades following the introduction of the snails. In the Philippines, PhilRice led in the basic and applied researches to manage the golden apple snail.
In 2006, PhilRice published the multi-authored book, Global Advances in Ecology and Management of Golden Apple Snails, edited by Dr. Ravindra C. Joshi and Leocadio S. Sebastian.
The present book, which is not a second edition of the 2006 book but a compilation of new research, advances in management and updated country reports, is in collaboration with the widely acknowledged apple snail expert Dr Robert H. Cowie, from the University of Hawaii, USA.
It reinterprets old problems and presents much of this new knowledge, with the lessons learned and knowledge available to inform management approaches more widely.
It is hoped that this new book will not only bring together this new knowledge in a single accessible place but also highlight the need to prevent the spread of these invasive species, especially in the context of a changing climate.
This book also brings together both basic and applied research on apple snails in efforts to further advance management and control of these major invasive and noxious pests and to support the farmers, extension workers, and others who are in the front lines of the battle against this species.
