Abstract

The following steps, as outlined in the plan, must be implemented before considering reclassification of the endangered masked bobwhite: 1) reestablishment of three or more self-sustaining populations in Arizona; 2) maintenance and/or reestablishment of one or more self-sustaining populations in Mexico; and 3) permanent protection of all habitat supporting these populations. (In the plan, a self-sustaining population is defined as an annual average of 200 or more calling males for at least 5 years.) In addition, the plan calls for interim maintenance of a captive population, as well as additional ecological and life history studies.

Freshwater and diadromous Fishes of Puerto Rico

Freshwater and Diadromous Fishes of Puerto Rico describes the diversity of fishes in Puerto Rico’s freshwater environments and provides information on the history of research, management and conservation, and culture of fish and fisheries in Puerto Rico. This book’s catalog of fishes guides the reader in the identification of more than 50 native and nonnative species of fish from 22 families that occur in Puerto Rico’s freshwater lagoons, rivers, streams, and reservoirs. Each species account includes a map of known occurrences, and a description of each species’ morphological characteristics, biology, and distribution. Freshwater and Diadromous Fishes of Puerto Rico is the result of decades of scientific research; however, it is intended to be accessible and useful to readers with a variety of backgrounds, including scientists, students, and outdoor enthusiasts such as recreational anglers and freshwater snorkelers. Conservation and management are underlying themes of Freshwater and Diadromous Fishes of Puerto Rico . Though the main goal of this book is to be a resource for the identification of Puerto Rico’s freshwater fishes, and on their biology and ecology, it is also intended to increase awareness of threats to these fishes and their value to people and ecosystems.
