Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

Snakes of the World: A Catalogue of Living and Extinct Species—the first catalogue of its kind—covers all living and fossil snakes described between 1758 and 2012, comprising 3,509 living and 274 extinct species allocated to 539 living and 112 extinct genera. Also included are 54 genera and 302 species that are dubious or invalid, resulting in recognition of 705 genera and 4,085 species. Features: Alphabetical listings by genus and species Individual accounts for each genus and species Detailed data on type specimens and type localities All subspecies, synonyms, and proposed snake names Distribution of species by country, province, and elevation Distribution of fossils by country and geological periods Major taxonomic references for each genus and species Appendix with major references for each country Complete bibliography of all references cited in text and appendix Index of 12,500 primary snake names The data on type specimens includes museum and catalog number, length and sex, and collector and date. The listed type localities include restrictions and corrections. The bibliography provides complete citations of all references cited in the text and appendix, and taxonomic comments are given in the remarks sections. This standard reference supplies a scientific, academic, and professional treatment of snakes—appealing to conservationists and herpetologists as well as zoologists, naturalists, hobbyists, researchers, and teachers.

A supplement to and partial revision of B-P-H (1968), this book contains over 25,000 title entries arranged alphabetically by title and is designed as a key to entries in both volumes. It features citation abbreviations for all titles, improved cross-referencing and an expanded thesaurus of title words and their abbreviation equivalents. The supplement includes periodicals dealing with biotechnology, molecular biology, environmental studies and conservation.

The book deals with push moraines on Spitsbergen. The main body is a translation of the original German report by Karl Gripp on a 1927 expedition. The quality of Gripp's work is evaluated to see whether it stands the test of time. It is found that it is very modern, every year people still go into the field with the same research questions. It is also found that most likely Gripp's report contains the first description of features that we now take for granted, for instance the description of looped moraines to detect surges. Push moraines are still being studied and to show where we stand now two papers have been added that analyse two particular examples, Holmströmbreen and Sefströmbreen. The two examples are geographically close together, but reflect two completely different settings: terrestrial Holmströmbreen and tidewater Sefströmbreen. Since a few years we know of the De Geer Archive, a collection of glass negatives of Spitsbergen, relating to De Geer's expeditions between 1882 and 1910. The negatives have only emerged recently and a collection of prints relating to Holmströmbreen and Sefströmbreen is included here. Together with a third paper incorporated in the book, this time an evaluation of De Geer's photos and maps of the Sefströmbreen surge, this material shows the importance of incorporating historical documentation in our studies.
