The limestone region of PR covers about 27% of the island1s surface and has karst features. The karst belt (KB), that part of the northern limestone with the most spectacular karst landforms, covering 65% of the northern limestone, is the focus here. Chapters: geography; features: geomorphological, hydrological, and ecological diversity; nat1l. resources; econ. importance: water, other minerals, ag., forestry, and environ. disturbances; history of intensive use; vulnerable to human activity: cutting vs. paved over forests, draining vs. filling wetlands, conversion vs. trans1n. of land uses, pumping vs. overdrafting aquifers, contaminating vs. poisoning ground water, and surface water pollution; and proposal for transferring KB to the public domain.

This is a revised edition of a widely praised guide to the birds of the largest of the Caribbean islands and the neighboring Virgin Islands. It includes detailed accounts of all 284 well-documented species known to occur in the region, 273 being illustrated. The book also contains specific sections entitled "Biogeography" and "Conservation" to foster an appreciation of the uniqueness of the region's wildlife and to develop an awareness of local conservation issues. The section "Places to Bird" will help make the stay of short-term visitors more productive. The book also substantially updates the data on avian distribution and abundance in the region covering records through November 1988. From reviews of the first edition: "This well-illustrated volume is a must for any student of birds visiting Puerto Rico or the Virgin Islands."--Chandler S. Robbins, The Quarterly Review of Biology "A valuable and informative guide."--James A. Dick, The Wilson Bulletin "This well-written book is the first comprehensive guide to the birds of Puerto Rico and the Virgin Islands. All species, including winter visitors (which comprise 47 percent of the avifauna) are described and illustrated, making a second volume for identification of North American migrants unnecessary. . . . Aside from being a fine field guide, the book contains useful summaries of the biogeography of the region and the ecology of avian populations. . . . A major contribution is Raffaele's presentation of a wealth of hitherto unpublished information on the natural history of the region's birds."--James W. Wiley, Ibis

In marked contrast to the United States, with its territorial stability, some countries, such as Bulgaria and Ethiopia, reorganize their regional subdivisions frequently. This large-format reference work simplifies the comparison of decades' worth of data from such countries: "With this book in hand, one can answer any administrative subdivision question about any state or province in the world from 1900 through 1998"--Abstracts of Public Administration, Development and Environment. For each country there is at least one table, and usually several. Histories of subdivision changes and lists of alternate names for subdivisions in each country add to the work's research value. All relevant national and international standards such as ISO and FIPS codes are listed, as well as time zones, populations, areas and capitals for each subdivision. There is a comprehensive index of names.
Many of Puerto Rico's cultural resources were devastated in Hurricanes Irma and Maria. The authors discuss their importance, the damage they endured immediately after the storms, and detail recovery actions in Puerto Rico's recovery plan.
