Book Description
Decapods are a culmination of nearly 600 million years of Crustacean evolution, during which time they have radiated into a variety of superfamilies, families, genera and species which occupy a variety of niches from fresh mountain streams to the abysses of the oceans. This book will fill a gap in the current literature on southern African decapods. Since Barnard published his Descriptive Catalogue of South African Decapod Crustacea in 1950, there have been numerous additions and name changes. This publication updates the taxonomy, and includes ecological and fisheries information. In addition, Kensley’s (1981) distributional checklist for the region has been updated and includes large numbers of new species and records for the region, bringing the total number of decapod to over 1000 species. Although not exhaustive, 262 species are featured, some of which are beautiful, some have commercial or artisinal value, both for consumption and the aquarium, and some have important ecological functions, while others are rare or interesting. For each species there is a photograph, synonymies, common names, a description, ecological information and name derivation (etymology). All the decapod families found in South Africa are described, some new, along with chapters on decapod research history in southern Africa, commercial and artisinal food value of decapods, biodiversity and future research direction. The book is arranged systematically, as taxonomy is based on phylogeny, starting with the earliest forms and progressing to the most derived and advanced forms, and will serve to stimulate interest and future research into southern Africa’s rich decapod biodiversity, especially at a time when biodiversity itself is threatened by global warming, coral bleaching and habitat loss. It will appeal to people interested in Decapoda, including academics, scholars, students, fishermen, aquarists, aquaculturists, recreational snorkel and SCUBA divers, as well as those interested in conservation, biodiversity, management and governance.

Book Description
An Introduction to Numerical Classification describes the rationale of numerical analyses by means of geometrical models or worked examples without possible extensive algebraic symbolism. Organized into 13 chapters, the book covers both the taxonomic and ecological aspects of numerical classification. After briefly presenting different terminologies used in this work, the book examines several types of biological classification, including classification by structure, proximity, similarity, and difference. It then describes various ecological and taxonomic data manipulations, such as data reduction, transformation, and standardization. Other chapters deal with the criteria for best computer classification and the complexities and difficulties in this classification. These difficulties are illustrated by reference to studies of the ""bottom communities"" of benthic marine invertebrates, ranging across the entire field from the sampling program and nature of the data to problems over the type of computer used. The concluding chapters consider some of the measures of diversity and the interpretations which have been made from them, as well as the relationship of diversity to classification. The concept and application in biological classification of various multivariate analyses are also discussed in these texts. Supplemental texts on the information measures, partitioning, and interdependence of data diversity are also provided. This book is of value to biologists and researchers who are interested in basic biological numerical classification.

Book Description
This illustrated atlas describes 256 extant brachyuran crab species in the Persian Gulf and the Gulf of Oman. Identification keys are provided for 37 brachyuran families, 144 genera and 256 species on the basis of their main synapomorphies. Brief but precise descriptions highlighting the main characteristics are also provided for every family. The atlas displays features high-quality color photos, offering a hands-on guide and equipping readers to readily diagnose crab species in the region. Importantly, a line drawing of the first male gonopod, as well as its main diagnostic characteristics, are provided for all species. Further, every species is supplemented with synonymies that encompass the original descriptions, overall revision of the given taxa, monographs and all records from the northwestern Indian Ocean including the Persian Gulf and the Gulf of Oman. For each species, the book provides detailed local and global distribution maps, together with important ecological data including habitat preference. Further, it includes a general introduction to the brachyuran crabs with schematic drawings of their external morphology, as well as a comprehensive introduction to the Persian Gulf and the Gulf of Oman as marine ecoregions (geography, hydrology, biology, and environmental condition). The book offers an indispensable guide for all professionals, researchers, and students interested in brachyuran crabs around the globe and particularly in the Persian Gulf and the Gulf of Oman.

Book Description
The published works are derived from the Zoological catalogue of Australia database. Taxa in the Australian fauna are divided among volumes to form sets of about 1800-2000 species available names, such that each volume comprises the whole or part of one or more major groups.
