Book Description
"The Carmine Shiner (Notropis percobromus) was listed under the Species at Risk Act (SARA) as Threatened when the Act came into force in 2003. In April 2006, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) re-assessed and confirmed the designation because it occurs in an extremely restricted area of Manitoba and the major threat to the species is the alteration in water flow as a result of stream regulation. The Science sector in Fisheries and Oceans Canada (DFO) was asked to undertake a Recovery Potential Assessment (RPA); this Research Document supports the RPA. It describes the current state of knowledge of Carmine Shiner in Manitoba in terms of their biology, ecology, abundance, distribution and trends, habitat requirements and threats. A recovery goal, mitigation measures and alternatives to threats and the potential for allowable harm are presented, as is information relevant to critical habitat and residence. The information contained in the RPA and this document may be used to inform the development of recovery documents and to support decision-making with regard to the issue of permits, agreements and related conditions under the SARA."--Document.

Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
This book provides the first synthesis of the remarkable diversity, evolutionary complexity, and conservation importance of the flora and fauna in the Mediterranean region, with emphasis on the three major peninsular refugia. The book highlights biodiversity importance in Southern Europe for European biota conservation, and includes chapters from authorities in phylogeography: John Avise, Remy Petit, Ettore Randi.

Book Description
Manitoba's ninety-three species of fish give the province the third most diverse fish population in Canada. The provinceís variety of geological features, with its major lakes, rivers, tributaries, and watersheds, is due in large part to its history as the basin for Glacial Lake Agassiz. This, combined with its access to the waters of Hudson Bay and large American river systems, has provided habitat for a wide diversity of freshwater fish. Species from lampreys to goldeye, catfish to perch, bigmouth bass to slimy sculpin swim in waters from arctic rivers in the north to Red River tributaries and down to the Mississippi in the south.Freshwater Fishes of Manitoba is a comprehensive, user-friendly guide. Each species is accurately depicted in detailed colour photographs and accompanying map, with descriptions of physical characteristics, spawning and feeding habits, distribution, habitat, ecological role, and economic importance. The guide also includes an extensive glossary, keys to identifying the families, species, and subspecies, and information on documentation and preservation of specimens. Freshwater Fishes of Manitoba is not only the definitive guide to these fishes of Manitoba, it is also accessible and reliable for a range of users from general fishers to professional fish biologists.

Book Description
While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.
