Book excerpt: This book presents the latest research on aquaculture which is the cultivation of aquatic organisms. Unlike fishing, aquaculture, also known as aquafarming, implies the cultivation of aquatic populations under controlled conditions. Mariculture refers to aquaculture practised in marine environments. Particular kinds of aquaculture include algaculture (the production of kelp/seaweed and other algae); fish farming; shrimp farming, shellfish farming, and the growing of cultured pearls.

Download or read book Animal Dispersal written by N.C. Stenseth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

Download or read book Environmental Signal Processing and Adaptation written by Gerhard Heldmaier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals and plants live in changing environmental conditions which require adaptation in order to cope with this. Some of these environmental changes serve as signals which have to be "sensed" and interpreted correctly by the organisms to initiate the adaptation. This signal processing is based on biochemical, molecular and neuronal processes which are discussed in this book. All examples given underline that continuous adjustment of physiological functions is an essential requirement for life and survival in complex changing environments.

Download or read book Mountain Goats written by Marco Festa-Bianchet and published by Island Press. This book was released on 2012-09-26 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain goats have been among the least studied of North American ungulates, leaving wildlife managers with little information on which to base harvest strategies or conservation plans. This book offers the first comprehensive assessment of the ecology and behavior of mountain goats, setting forth the results of a remarkable 16-year longitudinal study of more than 300 marked individuals in a population in Alberta, Canada. The authors’ thorough, long-term study allowed them to draw important conclusions about mountain goat ecology—including individual reproductive strategies, population dynamics, and sensitivity to human disturbance—and to use those conclusions in offering guidance for developing effective conservation strategies. Chapters examine: -habitat use, vegetation quality, and seasonal movements -sexual segregation and social organization -individual variability in yearly and lifetime reproductive success of females -age- and sex-specific survival and dispersal -reproductive strategies and population dynamics -management and conservation of mountain goats The book also draws on the rich literature on long-term monitoring of marked ungulates to explore similarities and differences between mountain goats and other species, particularly bighorn sheep and ibex. By monitoring a marked population over a long period of time, researchers were able to document changes in sex-age structure and identify factors driving population dynamics. Because it explores the links between individual life-history strategy and population dynamics in a natural setting, Mountain Goats will be an invaluable resource for wildlife managers, researchers in ecology and animal behavior, conservationists, population biologists, and anyone concerned with the ecology and management of natural populations, especially in alpine environments.
