Conifers are one of the world's most important resources of timber. If managed wisely and used sustainably, these resources will provide wood for a multitude of purposes, virtually indefinitely. Additional products include resins and their derivatives, and even medicinal extracts--for example taxol now used in the treatment of cancer. Conifers occur on all continents except Antarctica. Of the 630 species, 355 are listed as of conservation concern, with 200, or 25 of species, threatened with extinction. Although exploitation of these resources is as old as civilization, this century has seen a dramatic increase in the exploitation of timber resources. This action plan assess conifer diversity and its threats. It is unique among IUCN's Plant Action Plans so far published, in that it gives the complete global red list of conifers using the 1994 IUCN Red List Categories and criteria. Data is analyzed to identify "conifer hot spots", where conservation should be a priority, and a short-list of threatened species is prioritized.

A 2014 Choice Magazine "Outstanding Academic Title" An Atlas of the World's Conifers is the first ever atlas of all known conifer species. It is based on locality information of ca. 37,000 collected herbarium specimens held in scientific institutions. As well as providing natural distribution maps for each species, Farjon and Filer give the reader comprehensive insight into the biogeography, diversity and conservation status of conifers on all continents, dispelling the widely held view that they are primarily a northern boreal plant group. Conifer diversity is analysed and presented with a taxonomic and geographic perspective. Distribution patterns are interpreted using the latest information on continental drift, dispersal and phylogeny. The entire dataset supporting the Atlas can be consulted and verified online. These data can also be used for further research and are an invaluable resource for anyone working on conifer systematics, biogeography or conservation. An Atlas of the World’s Conifers indicates the known distribution of all conifers including an analysis of their biogeography, diversity and conservation status. Also available from Brill is Aljos Farjon’s A Handbook of the World's Conifers, published in 2010 (ISBN 978 90 04 17718 5) which is a 2017 Choice Magazine "Outstanding Academic Title".

This book is a collection of readings that explore environmental issues in Latin America and the Caribbean using natural science and social science methods. These papers demonstrate the value of interdisciplinary approaches to analyze and solve environmental problems. The essays are organized into five parts: conservation challenges; national policies, local communities, and rural development; market mechanisms for protecting public goods; public participation and environmental justice; and the effects of development policies on the environment.

00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.
