Book Description
This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Book Description
Beginning with the Grand Rapids Dam in the 1960s, hydroelectric development has dramatically altered the social, political, and physical landscape of northern Manitoba. The Nelson River has been cut up into segments and fractured by a string of dams, for which the Churchill River had to be diverted and new inflow points from Lake Winnipeg created to manage their capacity. Historic mighty rapids have shrivelled into dry river beds. Manitoba Hydro's Keeyask dam and generating station will expand the existing network of 15 dams and 13,800 km of transmission lines. In Our Backyard tells the story of the Keeyask dam and accompanying development on the Nelson River from the perspective of Indigenous peoples, academics, scientists, and regulators. It builds on the rich environmental and economic evaluations documented in the Clean Environment Commission’s public hearings on Keeyask in 2012. It amplifies Indigenous voices that environmental assessment and regulatory processes have often failed to incorporate and provides a basis for ongoing decision-making and scholarship relating to Keeyask and resource development more generally. It considers cumulative, regional, and strategic impact assessments; Indigenous worldviews and laws within the regulatory and decision-making process; the economics of development; models for monitoring and management; consideration of affected species; and cultural and social impacts. With a provincial and federal regulatory regime that is struggling with important questions around the balance between development and sustainability, and in light of the inherent rights of Indigenous people to land, livelihoods, and self-determination, In Our Backyard offers critical reflections that highlight the need for purposeful dialogue, principled decision making, and a better legacy of northern development in the future.
