This book was released on 2002 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rockfish belong to the speciose genus Sebastes (72 species described in the Northeast Pacific). Basic biological and life history information for many rockfish species is limited. Little is known about juvenile recruitment, and identification in early life stages is difficult because the larvae of congeners look similar and often occur in spatial and temporal association. Population genetic structure is an important element for characterization of species or populations, and may provide information on productivity and life history. Eight micro satellite loci were evaluated for variability in analyses of genetic structure for two species of rockfish: the deepwater shelf rockfish bocaccio (S. paucispinis) and the demersal shortraker rockfish (S. borealis) of the continental slope. Tests of homogeneity provided evidence of similar geographically based structure in both species, which is consistent with a neighbor model of gene flow. Structure inferred from this study provides information on the sizes of the basic units of productivity, which may aid in management and conservation efforts"--Leaf iii.

Book Synopsis Life History and Population Genetic Structure of Sea Stars from the Family Asterinidae by : Carson C. Keever
Download or read book Life History and Population Genetic Structure of Sea Stars from the Family Asterinidae written by Carson C. Keever and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history can influence population genetic variation by altering patterns of gamete union and dispersal. Sea stars from the family Asterinidae have evolved similar life histories multiple times in parallel including planktonic feeding larvae, planktonic non-feeding larvae, development in benthic egg masses, and viviparity. In this thesis I first examine the population genetic structure of a widespread planktotrophic asterinid sea star from the East Pacific (Patiria miniata). I use mitochondrial sequence markers to determine whether extrinsic factors such as vicariance or intrinsic properties such as dispersal mode are driving patterns of population genetic variation in this species. I then examine patterns of population genetic variation among eight additional asterinid species from Australia using a mixed species pool of genomic microsatellite markers. I use these microsatellite markers to characterize the genetic variation within groups of brooded offspring associated with the unusual life histories of two live bearing asterinids from the genus Parvulastra. Lastly, I examine the evolution of life history among the asterinids and use the phylogenetic relationships among species to examine the correlation between life history and population genetic structure in this group. Ultimately, I find that the degree to which intrinsic life history properties of asterinids and extrinsic factors contribute to population genetic variation varies among species and among clades. In P. miniata patterns of population genetic variation are influenced by both intrinsic and extrinsic factors. Using microsatellite markers I find that in general between-population genetic variation is high in benthic species (benthic egg laying and live bearing) relative to species with planktonic larvae and that genetic variation within populations is lower in benthic species relative to planktonic species. Lastly, I find that the degree to which phylogeny constrains the coevolution of population genetic structure and life history varies among life history characters and among-population genetic parameters. This thesis suggests that in many cases variation in life histories among a closely related group of marine species can predict patterns of population genetic variation. However, extrinsic factors can in some cases, act with or override life history characteristics in driving patterns of population genetic variation.
Book Synopsis Characterizing Population Genetic Structure and Inferring the Influence of Landscape Features on Gene Flow in a Temperate Snake Species by : Amanda Tonia Joan Xuereb
Download or read book Characterizing Population Genetic Structure and Inferring the Influence of Landscape Features on Gene Flow in a Temperate Snake Species written by Amanda Tonia Joan Xuereb and published by . This book was released on 2012 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patterns of genetic diversity in natural systems are influenced by landscape heterogeneity over spatial and temporal scales. Certain natural or anthropogenic landscape features may facilitate or impede organism dispersal and subsequent gene flow. Characterizing the geographical distribution of genetic diversity and identifying the factors contributing to population genetic structure is imperative for maintaining functional connectivity between isolated populations across a fragmented landscape. In this study, I combined genetic data and high-resolution land cover information to investigate patterns of population genetic structure in the threatened eastern hog-nosed snake (Heterodon platirhinos) at its northern range limit in Ontario, Canada. First, using putatively neutral microsatellite markers, I found evidence of genetic differentiation between two geographically disjunct regional populations: in the Carolinian region of southwestern Ontario, and along the eastern shoreline of Georgian Bay. Spatial and non-spatial Bayesian clustering algorithms also detected population genetic structure within each regional population. I found evidence of weak structure within Georgian Bay, roughly corresponding to regions north and south of Parry Sound. A genetic cluster at Wasaga Beach, located at the southern terminus of Georgian Bay, was highly differentiated from other populations, despite its geographic proximity to Georgian Bay. Excess homozygosity and reduced allelic diversity in Wasaga Beach compared to other sampled populations imply a population bottleneck event. Secondly, I inferred the role of landscape features on eastern hog-nosed snake dispersal and subsequent gene flow in the Georgian Bay regional population. Using techniques derived from electrical circuit theory, I estimated pairwise resistance distances between individuals by assigning costs to landscape features that are predicted to impede hog-nosed snake movement: open water, wetland, settlement and agriculture, and roads. Landscape features did not influence genetic structure within Wasaga Beach. However, I found weak evidence for an effect of landscape features, particularly open water and roads, on gene flow in eastern Georgian Bay. This study is the first to examine potential factors driving population genetic structure of eastern hog-nosed snakes and provides an empirical foundation for future tests of demographic models and spatially explicit simulations of gene flow.

Book excerpt: Fishes are the most abundant vertebrates in the animal kingdom. They play important biological and ecological roles. Various anthropogenic and climatic factors have led to the decline of natural population and increased the risk of extinction. CBD emphasized the conservation of biodiversity at all levels from genes to ecosystems. However, little attention paid to genetic considerations in restoration efforts. Estimation of genetic diversity and population structure is inevitable for effective implementation of conservation management program. Available DNA markers like mitochondrial and microsatellite markers provide useful insight into understanding the genetic diversity status of fish population in the wild. The present chapter highlights the importance of genetic diversity and its determinants. Utility of mitochondrial and microsatellite markers shown through a case study of a threatened cyprinid species Neolissochilus hexagonolepis known as chocolate mahseer that is widely distributed in the North-eastern part of India. Presence of low genetic diversity confirmed its threatened status and further analysis based on various genetic parameters revealed the status of different stocks as well as the population structure of this species. The results obtained could be helpful in rehabilitation and conservation planning and prioritization for the maintenance of a viable population of this species.

This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Available in PDF, EPUB and Kindle. Book excerpt: Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

This book was released on 2012-07-26 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological diversity is important for ecosystem function and services, which in turn is essential for human well-being. Under the Convention on Biological Diversity, international efforts have been made to achieve a significant reduction in the current rate of biodiversity loss. The loss continues, however. The Asia-Pacific region includes both developing countries with high biodiversity and developed countries with sophisticated data collection and analyses, but only limited information about the status quo of biodiversity in this region has been available. Many Asia-Pacific countries have rapidly grown their economies and social infrastructures, causing a loss of biodiversity and requiring an urgent mandate to achieve a balance between development and conservation in the region. In December 2009, scientists successfully organized the Asia-Pacific Biodiversity Observation Network in the region, to establish a network for research and monitoring of ecosystems and biodiversity and to build a cooperative framework. The present volume is the first collection of information on biodiversity in the Asia-Pacific and represents a quantum step forward in science that optimizes the synergy between development and biodiversity conservation.
