Book Description
The present volume contains the contributions of the keynote speakers of the BIOMAT 2007 Symposium as well as selected contributed papers in the areas of mathematical biology, biological physics, biophysics and bioinformatics. It contains new results on some aspects of Lotka-Volterra equations, the proposal of using differential geometry to model neurosurgical tools, recent data on epidemiological modeling, pattern recognition and comprehensive reviews on the structure of proteins, the folding problem and the influence of Allee effects on population dynamics.This book contains some original results on the growth of gliomas: the role played by membrane channels on activity-dependent modulation of spike transmission; a proposal for reconsidering the concept of gene and the understanding of the mechanisms responsible for gene expression; a differential geometric approach to the influence of the drying effect on the dynamics of pods of Leguminosae; the comparison of agent-based models with the approach of differential equations on the study of selection mechanisms in germinal centers; and the synchronization phenomenon for protocell systems driven by linear kinetic equations.

Book Description
After the chicken, the House Sparrow is the most widely distributed bird species in the world, occurring on all continents except Antarctica and on most human-inhabited islands. Although its Latin name is Passer domesticus, it is certainly not domesticated. In fact, it is widely regarded as a pest species and is consequently not protected in most of its extensive range. This combination of ubiquity and minimal legal protection has contributed to its wide use in studies by avian biologists throughout the world. The purpose of this book is to review and summarize the results of these global studies on House Sparrows, and to provide a springboard for future studies on the species. House Sparrows have been used to study natural selection in introduced species, circadian rhythms, and the neuroendocrine control of the avian annual cycle. One current question of considerable interest concerns the catastrophic House Sparrow population declines in several urban centers in Europe. Is the House Sparrow a contemporary canary in the mine? Other topics of broad interest include the reproductive and flock-foraging strategies of sparrows, and sexual selection and the function of the male badge in the species. Anderson also explores the role of the House Sparrow in disease transmission to humans and their domesticated animals.

Book Description
Biodiversity of Pantepui: The Pristine "Lost World" of the Neotropical Guiana Highlands provides the most updated and comprehensive knowledge on the biota, origin, and evolution of the Pantepui biogeographical province. It synthesizes historical information and recent discoveries, covering the main biogeographic patterns, evolutionary trends, and conservational efforts. Written by international experts on the biodiversity of this pristine land, this book explores what makes Pantepui a unique natural laboratory to study the origin and evolution of Neotropical biodiversity under the influence of only natural drivers. It discusses the organisms living in Pentepui, including algae, plants, several groups of invertebrates, birds, amphibians, reptiles, and mammals. The latter portion of the book delves into the effects of human activity and global warming on Pantepui, and current conservational efforts to combat these threats. Biodiversity of Pantepui is an important resource for researchers in ecology, biogeography, evolution, and conservation, who want to understand the biodiversity and natural history of this region, and how to help conserve and protect the Guiana Highlands from environmental and human damages. - Offers a climactic and ecological history of the region since the Late Glacial epoch - Discusses the evolutionary origin of the Pantepui biota and its biogeographical patterns - Led by a team of editors whose expertise includes Pantepui, the Guiana Shield, and the Neotropics in general

Book Description
The generation of electricity by wind energy has the potential to reduce environmental impacts caused by the use of fossil fuels. Although the use of wind energy to generate electricity is increasing rapidly in the United States, government guidance to help communities and developers evaluate and plan proposed wind-energy projects is lacking. Environmental Impacts of Wind-Energy Projects offers an analysis of the environmental benefits and drawbacks of wind energy, along with an evaluation guide to aid decision-making about projects. It includes a case study of the mid-Atlantic highlands, a mountainous area that spans parts of West Virginia, Virginia, Maryland, and Pennsylvania. This book will inform policy makers at the federal, state, and local levels.

Book Description
Widespread across open lands and cities of Europe, Africa, and Asia, the common kestrel (Falco tinnunculus) is one of the most abundant and studied birds of prey. This book brings together and synthesises the results of research on kestrels for professional ornithologists and scientists that seek to consolidate a vast body of literature. It is also a reference for those readers who may not have the depth of scientific knowledge to navigate new fields of scientific enquiry. It examines many aspects of the species' biology, from the reproductive strategies to the behavioural and demographic adaptations to changes of environmental conditions. It also discusses the roles of physiology and immunology in mediating the adaptability of kestrels to the ongoing environmental changes with a particular focus on contaminants. This volume presents new and exciting avenues of research on the ecology and behaviour of the common kestrel.

Book Description
In this unique and unprecedented study of birding in Africa, historian Nancy Jacobs reconstructs the collaborations between well-known ornithologists and the largely forgotten guides, hunters, and taxidermists who worked with them. Drawing on ethnography, scientific publications, private archives, and interviews, Jacobs asks: How did white ornithologists both depend on and operate distinctively from African birders? What investment did African birders have in collaborating with ornithologists? By distilling the interactions between European science and African vernacular knowledge, this stunningly illustrated work offers a fascinating examination of the colonial and postcolonial politics of expertise about nature.

Book Description
Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.
