Soay sheep : dynamics and selection in an island population by T. H Clutton-Brock( Book )

11 editions published between 2003 and 2004 in English and held by 261 WorldCat member libraries worldwide

"Soay Sheep synthesises the results of a unique study of population dynamics, selection and adaptation in a naturally regulated population of mammals. Soay sheep were first introduced to the St Kilda archipelago in the Bronze age, and to the island of Hirta in 1932, where their numbers are naturally regulated by the availability of resources. Unlike most other large mammals, their numbers show persistent fluctuations, sometimes increasing or declining by more than 60 per cent in a year. Soay Sheep explores the causes of these fluctuations and their consequences for selection on genetic and phenotypic variation within the population, drawing on nearly twenty years' study of the life-histories and reproductive careers of many individuals. The study provides important insights into the regulation of other herbivore populations and the effects of environmental change on selection and adaptation. It will be essential reading for vertebrate ecologists, demographers, evolutionary biologists and behavioural ecologists."--Jacket

Genotype by environment interactions in winter survival in red deer by T. N Coulson( Book )

1 edition published in 1998 in English and held by 2 WorldCat member libraries worldwide

1. The extent to which environmental heterogeneity interacts with genetic heterogeneity to affect individual fitness within populations has the potential to affect the dynamics of natural populations and the amount of genetic variation maintained in natural populations, yet is a relatively poorly investigated topic in either ecology or evolutionary biology. 2. Many individual-based studies are precluded from such investigations by the practical problems of measuring heritability of traits affecting fitness and the difficulties of experimental manipulation of the study population. One way of demonstrating how commonly genotype by environmental interactions affect fitness, though not their overall importance in determining fitness, is to investigate fitness in a population subdivided by genotype at one or more marker loci. 3. We analyse data on calf winter survival from a population of red deer from the Isle of Rum, Scotland. Data on individual survival, environmental fluctuations and ge

Repeated selection of morphometric traits in the Soay sheep on St. Kilda by J. M. (Jos) Milner( Book )

1 edition published in 1999 in English and held by 2 WorldCat member libraries worldwide

1. Long-term studies allow the outcomes of repeated selection events to be monitored. Here, we investigate phenotypic selection in successive winter mortality events in the Soay sheep of St Kilda, Scotland, between 1985 and 1996. Selection of three quantitative morphometric traits, body weight, hindleg length and incisor arcade breadth, was investigated in different sectors of the population. 2, Evidence from fitness differentials of positive directional selection for large size was repeatedly found in lambs and adult females. Selection in the opposing direction was only found in one year in lambs. 3. Selection gradients showed that in most years when significant selection occurred, body weight was the focus of direct selection, whereas selection of hindleg length and incisor breadth was indirect, arising from their correlation with body weight. 4, Selection was strongest in years of low over-winter survival and almost absent in years when survival was high. Intensity of selection was greatest in lambs, emphasizing the differences in selection pressure experienced by different sectors of the population, in addition to the temporal variation in selection pressure due to population density and environmental conditions. 5. Despite repeated positive selection of body weight, no evidence of a change in the population mean was found over the course of the study

Selection and genetic variation of weaponry in a large mammal by Matthew R Robinson( )

2 editions published in 2008 in English and held by 2 WorldCat member libraries worldwide

Understanding the maintenance of the variation that is typically observed in natural populations has been a central aim of evolutionary biology. In a feral population of Soay sheep on the island of Hirta, St. Kilda there is a phenotypic polymorphism for horns with males growing either normal or reduced (scurred) horns, and females growing either normal, scurred or no (polled) horns, with further variation in horn size within each of the horn types. This thesis examines the potential factors which maintain these polymorphisms. I first present an overview of the literature relating to the factors that potentially maintain variance in traits in natural populations. In chapter two I present an analysis that suggests that polymorphisms in both horn type and horn size may be maintained by trade-offs between allocation to reproductive success and survival in males, and by sexually antagonistic selection between males and females. In chapter three I test the hypothesis that female weaponry may convey an advantage in intrasexual conflicts over resources, rather than just being expressed as a consequence of genetic associations with the male phenotype. Chapter four examines the environmental factors which create variation between individuals in their horn length, revealing that individuals vary in response to the environment. In chapter five I investigate whether the temporally fluctuating environmental conditions of St. Kilda generate fluctuating selection on the horn length of normal-horned males, revealing that this mechanism constrains the evolution of horn length potentially maintaining variance. In chapter six I examine the genetic relationships between morphological traits, revealing that these relationships are dependent upon the environmental conditions experienced during the first year of life. Finally, I discuss the wider implications of these findings for our understanding of the maintenance of trait variation in the wild

J. M. Pemberton recipe book by J. M Pemberton( )

in English and held by 1 WorldCat member library worldwide

An oversize volume with parchment covers comprised of culinary and household recipes spanning the years from 1840-1892. Most of the recipes are between the years 1844 and 1875. Inscribed on the inside back cover: J. [M.] Pemberton's book, Gibraltar, Leeds, 1844. The inside front cover and first three unnumbered pages comprise a table of contents listing the recipe and page number. "List of French and other foreign words ..." is on the next three pages. Numbered pages 1-56 comprise the recipes listed in the table of contents followed by eight leaves. The culinary recipes written in the volume are for breads, cakes, jellies, meat dishes, picklings, puddings, rice dishes, and wines. There are several cakes including ground rice, spice, and Wakefield gingerbread. Puddings include carrot, castle, scalded, and Sir Martin's. A recipe for Parkin, a Yorkshire gingerbread cake associated with Leeds. Several household recipes include cleaners, blacking, pastes, and polishes. A few medicinal and toiletry recipes include remedies for chapped hands, coughs, and inflamed eyes and mixtures for hair. A poem is written on the last leaf of the volume. Many recipes are dated with attributions such as Jane Hammond, Mrs. J. Pemberton, the Family herald, the London journal, and the Young ladies journal. Six small leaves of recipes are laid in the volume. A letter dated April 14, 1892 from M. Wilkinson to Mrs. Rhodes with a recipe for whooping cough is laid in the volume. The spine of the volume is cracked and has loose covers and leaves
