This book was released on 1991 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study addresses the effects of the abundance and proximity of competition from non-crop perennials on the performance of planted black spruce and jack pine seedlings. Both container and bare-root stock of each species are included because physiological differences after outplanting have been reported between the stock types. The study formulated a monomial (single-term) index of perennial vegetative competition, using distance-based criteria for the inclusion of competitors. The indices were derived from either vertical hemispherical photographs or field measurements but differed as to the number and proximity of the surrounding competitors included. The optimum index was calculated as the amount of competing canopy on a vertical hemispherical photograph in relation to the seedling leaf area. An alternative index that also performed well was the sum of the relative competing stem volumes based on one dominant competitor in each quadrant surrounding the seedling.

Download or read book Sperm Competition and the Evolution of Animal Mating systems written by Robert L. Smith and published by Elsevier. This book was released on 2012-12-02 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.
