The potential for numerous amphibian species to go extinct in Oaxaca and Chiapas is high and worthy of being considered a major environmental problem. This report summarizes the findings of a project aimed at gathering information at 16 sites in southern Mexico which had been identified in 2005 as being essential to the continued existence of 22 highly threatened amphibian species, the hope being that it could help initiate conservation action. Site and species information are presented as a series of profiles.

This volume is a comprehensive, fully illustrated catalogue of the sharks, batoid fishes, and chimaeras of the Indian Ocean. It includes 10 orders, 23 families, 45 genera, and 78 species of cartilaginous fishes, providing accounts for all orders, families and genera, and all keys to taxa are fully illustrated.

This unique book offers a comprehensive guide to the fascinating world of polystomatid flatworms. It introduces the reader to the individual life histories of polystomes and the chronological advances in our knowledge, with descriptions of species discovered over the past centuries. It equips newcomers to the field with basic protocols and techniques for collecting, processing and interpreting material. It also presents the history of research on this group of parasites, provides information on the discovery of each polystome and acknowledges the authors that have made major contributions. For the established researcher in the field, it offers a reference book containing taxonomic data, measurements and drawings of all known polystomes. The authors have brought together all the available material, creating a resource that will stimulate research and revive the global focus on this unique group of parasites. Thus, this work provides an essential reference for both established researchers and newcomers to the field.

"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."

Frankincense, also called olibanum, is an aromatic resin used since ancient times for incense, perfume and aromatherapy. It is readily available as an essential oil or as a supplement or extract, and studies have shown that it may enhance heart health and liver health and soothe pain and inflammation. This new volume is a comprehensive desktop reference book specifically gum olibanum - frankincense. It introduces the significance of the species and covers the botany, phytochemistry, propagation, extraction, and pharmacological uses. It also discusses the species’ genetic diversity using molecular markers, in vitro propagation and biotechnological aspects of Boswellia species, the trade and commerce of frankincense, and as well as its threats and conservation.

This book includes all 14 articles contributed to the Special Issue "Systematics and Conservation of Neotropical Amphibians and Reptiles” in the journal Diversity, originally published in 2019 and 2020.

These proceedings contain 49 papers presented in the following sections: (i) crop wild relative conservation; (ii) establishing inventories and conservation priorities; (iii) threat and conservation assessment; (iv) genetic erosion and genetic pollution; (v) in situ conservation; (vi) ex situ conservation; (vii) information management; (viii) gene donors for crop improvement; (ix) use of crop wild relatives and underutilized species; and (x) global issues in crop wild relative conservation and use.

The book is the first comprehensive analysis of the macroecology and geobotany of endemic vascular plants with case-studies and analyses from different regions in the world. Endemism is a pre-extinction phenomenon. Endemics are threatened with extinction. Due to international nature conservation policies and due to the perception of the public the concept’s importance is increasing. Endemism can result from different biological and environmental processes. Depending on the process conservation measures should be adapted. Endemic vascular plant taxa, in the setting of their species composition and vegetation types are important features of landscapes and indicators of the quality of relating habitats. The book is an important basis for biologists, ecologists, geographers, planners and managers of nature reserves and national parks, and people generally interested in nature conservation and biogeography of vascular plants.
