Abstract

Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Abstract

Fish genetic resources (FiGR) comprise all finfish and aquatic invertebrate genetic material that has actual or potential value for capture fisheries and aquaculture. In capture fisheries more species are becoming endangered and more stocks overexploited. Management of FiGR can help maintain and rebuild these fisheries. Deep-sea fisheries and modern genetic technologies are emerging areas that require attention. Improved information is necessary for improved policies, but at present it is incomplete, scattered and unstandardized. Although tremendous progress has been made in the genetic improvement, genetic stock identification and genomics of aquatic species, further work is needed to: i) assess the status of FiGR in capture fisheries and aquaculture; ii) improve the capacities of scientists, technical persons, governments and industry; iii) improve facilities for characterizing FiGR; iv) develop genetically improved farmed types of aquatic species; v) develop appropriate policy instruments on use and conservation of FiGR; vi) improve general awareness and levels of knowledge about FiGR; and vii) prioritize species, geographic areas and production systems on which to expend resources for conservation and use of FiGR.--Publisher's description.
