Evaluation of Closed-containment Technologies for Saltwater Salmon AquacultureThis book informs proponents and opponents of saltwater salmon aquaculture of the current state of closed-containment technologies to restrict and control interactions between farmed fish and the external aquatic environment. In addition to an introductory chapter, there are six chapters written by renowned experts, including a review of past experiences and 42 case studies from around the world, reviews of biological and animal health requirements for commercial-scale rearing of salmon, a review of engineering designs for floating systems and a review of the five types of production system available for rearing of Atlantic salmon.

Manual of Central America DipteraVolume 2True flies, or Diptera, are an exceedingly diverse and tremendously important group of animals not only because of their impact on human health, but also because of their varied roles as decomposers, herbivores, predators and parasites of other animals. This two-volume book, a collaboration of over 70 experts on Diptera, is the first-ever resource for the identification and understanding of Central American flies. [

Late Ordovician and Early Silurian stromatoporoid sponges from Anticosti Island, eastern Canadacrossing the O/S mass extinctionDuring Late Ordovician and Early Silurian time, from 450 to 428
million years ago, stromatoporoid sponges were some of the
most common and abundant fossils in shallow water tropical
settings of the Anticosti Basin (Gulf of St Lawrence). They
formed dense, massive coralline skeletons of calcium carbonate,
some up to a meter or more across, especially in reef
environments, but also in deeper waters of the Anticosti shelf,
down to the margins of the photic zone, where light faded. The
Anticosti Basin reveals one of the most fossiliferous carbonate
sequences worldwide for rocks of this age, straddling a global
mass extinction boundary, and thus revealing not only those
taxa that became extinct, but also how the seas were
repopulated in an equatorial setting after the mass extinction. [

Assessment of Species Diversity in the Atlantic Maritime EcozoneThis illustrated volume provides the first comprehensive introduction to species diversity in the ecozone that encompasses New Brunswick, Nova Scotia, Prince Edward Island and parts of Quebec. It describes the regional flora and fauna, from fungi to mammals, and explores post-glacial history, aquatic habitats, and protected areas. [
