Описание: In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pol-linate the equally intriguing plants in an ecological circle of sustainability.
The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming's eleven-year study of the pollination biology of these species at a site he named Tortilla Flats in Sonora, Mexico, near Kino Bay.
Now Fleming shares the surprising results of his intriguing work. Among the novel findings are one of the world's rarest plant-breeding sys-tems in a giant cactus; the ability of the organ pipe cactus to produce fruit with another species' pollen; the highly specialized moth-cactus pollination system of the senita cactus; and the amazing lifestyle of the lesser long-nosed bat, the major nocturnal pollinator of three of these species.
These discoveries serve as a primer on how to conduct ecological re-search, and they offer important conservation lessons for us all. Fleming high-lights the preciousness of the ecological web of our planet--Tortilla Flats is a place where cacti and migratory bats and birds connect such far-flung habitats as Mexico's tropical dry forest, the Sonoran Desert, and the temper-ate rain forests of southeastern Alaska. Fleming offers an insightful look at how field ecologists work and at the often big surprises that come from looking carefully at a natural world where no species stands alone.

Mountain regions encompass nearly 24 percent of the total land surface of the earth and are home to approximately 12 percent of the world's population. Their ecosystems play a critical role in sustaining human life both in the highlands and the lowlands.
During recent years, resource use in high mountain areas has changed mainly in response to the globalization of the economy and increased world population. As a result, mountain regions are undergoing rapid environmental change, exploitation, and depletion of natural resources leading to ecological imbalances and economic unsustainability. Moreover, the changing climatic conditions have stressed mountain ecosystems through higher mean annual temperatures and the melting of glaciers and snow. Altered precipitation patterns have also had an impact.
This book addresses these critical issues and looks at ways to stop the downward spiral of resource degradation, rural poverty, and food and livelihood insecurity in mountain regions. The book also discusses new and comprehensive approaches to mountain development that are needed to identify sustainable resource development practices, how to strengthen local institutions and knowledge systems, and how to increase the resilience between mountain environments and their inhabitants.

Описание: There are more than 180 exotic species in the Great Lakes. Some, such as green algae, the Asian tapeworm, and the suckermouth minnow, have had little or no impact so far. But a handful of others—sea lamprey, alewife, round goby, quagga mussel, zebra mussel, Eurasian watermilfoil, spiny water flea, and rusty crayfish—have conducted an all-out assault on the Great Lakes and are winning the battle. In Lake Invaders: Invasive Species and the Battle for the Future of the Great Lakes, William Rapai focuses on the impact of these invasives. Chapters delve into the ecological and economic damage that has occurred and is still occurring and explore educational efforts and policies designed to prevent new introductions into the Great Lakes.Rapai begins with a brief biological and geological history of the Great Lakes. He then examines the history of the Great Lakes from a human dimension, with the construction of the Erie Canal and Welland Canal, opening the doors to an ecosystem that had previously been isolated. The seven chapters that follow each feature a different invasive species, with information about its arrival and impact, including a larger story of ballast water, control efforts, and a forward-thinking shift to prevention. Rapai includes the perspectives of the many scientists, activists, politicians, commercial fishermen, educators, andboaters he interviewed in the course of his research. The final chapter focuses on the stories of the largely unnoticed and unrecognized advocates who have committed themselves to slowing, stopping, and reversing the invasion and keeping the lakes resilient enough to absorb the inevitable attacks to come.Rapai makes a strong case for what is at stake with the growing number of invasive species in the lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action. Although this volume tackles complex ecological, economical, and political issues, it does so in a balanced, lively, and very accessible way. Those interested in the history and future of the Great Lakes region, invasive species, environmental policy making, and ecology will enjoy this informative and thought-provoking volume.

Описание: This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. Both accidental and deliberate movements of species are involved, with alien invasive plants and insects the major groups of concern for their influences on native insects and their environments. Risk assessments, stimulated largely through fears of non-target impacts of classical biological control agents introduced for pest management, have provided valuable lessons for wider conservation biology. They emphasise the needs for effective biosecurity, risk avoidance and minimisation, and evaluation and management of alien invasive species as both major components of many insect species conservation programmes and harbingers of change in invaded communities. The spread of highly adaptable ecological generalist invasive species, which are commonly difficult to detect or monitor, can be linked to declines and losses of numerous localised ecologically specialised insects and disruptions to intricate ecological interactions and functions, and create novel interactions with far-reaching consequences for the receiving environments. Understanding invasion processes and predicting impacts of alien species on susceptible native insects is an important theme in practical insect conservation.

Описание: Based on graph theory studies this book seeks to understand how tropical species interact with each other and how these interactions are affected by perturbations in some of the most species-rich habitats on earth. Due to the great diversity of species and interactions in the tropics, this book addresses a wide range of current and future issues with empirical examples and complete revisions on different types of ecological networks: from mutualisms to antagonisms. The goal of this publication is not to be only for researchers but also for undergraduates in different areas of knowledge, and also to serve as a reference text for graduate-level courses mainly in the life sciences.
Автор: Mar?a de Lourdes Torres; Carlos Mena Название: Understanding Invasive Species in the Galapagos Islands ISBN: 3319671766 ISBN-13(EAN): 9783319671765 Издательство: Springer Рейтинг: Цена: 111790.00 T Наличие на складе: Есть у поставщика Поставка под заказ. Описание: This book investigates the introduction of invasive species and their behavior in oceanic islands. How can we define invasive species? What is their history? How did they come to dominate and transform ecosystems? These are relevant questions when trying to understand the behavior of invasive species—primarily in fragile ecosystems such as islands—and to understand the biological, ecological, social and economic impacts of invasions.
We chose the Galapagos Islands, a place well-known to be unique in the study of evolution, as a laboratory to analyze the interactions between invasive and endemic species, to understand the makeup of the ecosystems emerging after invasions have occurred, to describe the relationships of invasives with the people that live in these islands, and to try to develop comprehensive analyses on this topic from multi-scalar and multi-disciplinary points of view. For a long time, the discussion has been about how proper management of the species could achieve two main goals: the eradication of the species to recover affected ecosystems and the conservation of endemic species. The discussion has taken on other nuances, including the suggestion that an invasive species, when it is already adapted to an ecosystem, forms an integral part of it, and thus eradication would in itself go against conservation. On the other hand, some invasive species are not only part of the biological compound of the island ecosystems, but they also form part of the social and cultural history of the inhabited islands. Some of these identified by the local inhabitants are species of real or potential economic value.

Автор: Zachos Название: Species Concepts in Biology ISBN: 3319449648 ISBN-13(EAN): 9783319449647 Издательство: Springer Рейтинг: Цена: 149060.00 T Наличие на складе: Есть у поставщика Поставка под заказ. Описание: Frank E. Zachos offers a comprehensive review of one of today’s most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name (“species”) is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.
