This book was released on 2017 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: A persistent challenge for ecologists is characterizing patterns of diversity in community structure, and understanding the importance of species interactions that shape communities across environments. Both foundation and invasive species have strong influences on community diversity and structure, though they have historically been thought to have opposite effects. While foundation species provide habitat to other species and have a net positive effect on diversity, invasive species tend to modify the habitat, displace native species, and decrease diversity. However, there are more recent examples of positive interactions between invasive species and native species, where invasive species provide novel or superior habitat for the community. Furthermore, the ranges of invasive species can encompass a wide variety of environments and communities, thus both their traits and effects on the community are likely to differ across environments. Understanding whether invasive species exhibit context-dependent trait differentiation and community-level effects is useful for understanding how their net effects on the community may differ throughout their invasive range. Watersipora subtorquata is an invasive bryozoan that has been considered a foundation species and has spread to a wide range of environments throughout the West coast of the United States, Hawaii, Australia, New Zealand, Europe, and South Africa. Using field surveys, year-long monitoring, and experiments in two harbor environments within the California range of W. subtorquata, I examined 1) spatial variation in the abundance of W. subtorquata and community structure and diversity, 2) how traits of W. subtorquata differ temporally across environments, and 3) to what extent W. subtorquata benefits the community as a foundation species and whether the direction and magnitude of its effects on the community differ across its invasive range. Field surveys revealed that fouling community diversity significantly differed across environments, and had a non-linear relationship with W. subtorquata abundance that differed between environments. Year-long monitoring provided evidence that W. subtorquata may be a better competitor for space in the seasonally variable environment of Bodega Harbor, and greater recruitment in the more stable environment of Alamitos Bay. Finally, a field experiment showed that while W. subtorquata does not facilitate diversity of mobile or sessile invertebrates, it does alter the community structure. It facilitates diversity of some arthropod and isopod species, but competes strongly with sessile tunicate and bryozoan species for space on the tiles. However, these net effects differed across environments, highlighting the potential for W. subtorquata to have varied effects on communities as it expands its range.

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

New insights into the impacts arising from biological invasions are generated through taking an ecosystem services perspective. This work highlights that management of biological invasions is needed not only to sustain biodiversity and the environment, but also to safeguard productive sectors such as agriculture, forestry and fisheries, as well as to preserve human health and well-being.

Download or read book Invasive Species in a Globalized World written by Reuben P. Keller and published by University of Chicago Press. This book was released on 2015 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global trade and the spread of human populations have increasingly moved thousands of native animal and plant species across the natural barriers that have kept them ecologically separated for millions of years. Because some of them thrive in their new regions and harm the environment, the economy, and human health, the prevention and management of such invasive species has become a major local, national, and international policy initiative. Yet even though ecologists have been studying the negative (and sometimes positive) environmental impacts of invasive species and trying to curb their proliferation, and even though their work has in some cases stimulated public conversation and policy, politicians have generally ignored their recommendations. As a result, ecologists have achieved limited success in slowing the spread of invasives. They ve been realizing that in order to fully characterize the impacts of these species, they need to engage with other relevant disciplines across the social and legal sciences as well as the humanities. Drawing together a wide variety of ecologists, historians, economists, legal scholars, policymakers, and communication scholars, Invasive Species in a Globalized World aims to facilitate a dialogue among these various disciplines in order to fully understand invasives and stop their spread. Addressing the numerous challenges associated with reducing invasive impacts, the contributors provide direct policy recommendations, strategies for communicating the risks of invasive species, and insight into how public discourse drives our response to these risks."

Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.

Book excerpt: Encyclopedia of the Anthropocene, Five Volume Set presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time

Download or read book Organism and Environment written by Sonia E. Sultan and published by . This book was released on 2015 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments. This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms (ecological development or 'eco-devo'), and how organisms in turn alter their environments (niche construction). A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism-environment effects. This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes, ecological success, and evolutionary prospects of organisms in rapidly changing environments. Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology, evolution, and developmental biology, as well as academics and researchers in these fields.

Download or read book Invasive Species Ecology Impacts and Potential Uses written by Vinícius Londe and published by . This book was released on 2020-07 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive plant species are becoming common and dominating virtually all environments worldwide. Their impacts on native biota can be variable, but they normally negatively affect the resident species. The interest in invasive species has grown in recent decades and many studies are being conducted on this theme. In this book, we quantitatively demonstrate how the interest in invasive plants has increased since 2000, and which topics have received more attention over time. Moreover, we report a variety of information on plant and animal invasive species inhabiting different ecosystems. A temporal and spatial analysis of the New Zealand Mud Snail is presented, as well as the expansion of the Brazilian rattlesnake distribution. Many studies were carried out on the (magnificent) Fernando de Noronha archipelago in the last decade, and the results are partially described in this volume. Native plants and animals are being threatened by exotic and invasive species in the archipelago. Protected areas nearby urban centers are especially affected by invasive species, and this statement is confirmed herein through a study carried out in Atlantic Forest remnants. Another interesting issue is how exotic and invasive tree species can affect the diversity and structure of epiphyte species. Herein the reader will learn how an invasive species sets up the epiphyte community in a century old oil palm stand. Although invasive species cause serious problems in the new environment, some of them can also be used to mitigate air, water, and soil pollution. Thus, in addition to presenting the ecological aspects and negative effects, this volume also brings some potential uses for invasive species.

This book was released on 2015-01-01 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: When organisms are deliberately or accidentally introduced into a new ecosystem a biological invasion may take place. These so-called ‘invasive species’ may establish, spread and ecologically alter the invaded community. Biological invasions by animals, plants, pathogens or vectors are one of the greatest environmental and economic threats and, along with habitat destruction, a leading cause of global biodiversity loss. In this book, more than 50 worldwide invasion scientists cover our current understanding of biological invasions, its impacts, patterns and mechanisms in both aquatic and terrestrial systems.

Download or read book Bioeconomics of Invasive Species written by Reuben P. Keller and published by Oxford University Press. This book was released on 2009-04-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are one of the strongest drivers of global environmental change, and invasive species are now often in the public discourse. At the same time, economists have begun to take a real interest in determining how invasive species interact with economic systems, and how invaders should be controlled to optimize societal wealth. Although the work from ecologists and economists have both greatly expanded our understanding of the drivers and impacts of invasions, little integration between the fields has occurred that would allow managers and policy-makers to identify the optical expenditures on, for example, prevention and control of invasive species. Because the level of effort expended on invasive species management is intricately linked to the costs and projected benefits of that management, there is an urgent need for greater synthesis between ecology and economics. This book brings ecology and economics together in new ways to address how we deal with the dynamics and impacts of invasive species, and is the outcome fo many years of collaborative research between a small group of economists and ecologists. The outcome is clear demonstration of the utility of combining ecological and economic models for addressing critical questions in the management of invasive species.

Download or read book Community Pest Management in Practice written by Tanya M. Howard and published by Springer. This book was released on 2018-12-13 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a collection of practitioner and community stories that reveal how invasive species management is a community issue that can spark community formation and collective action. It combines the unique first-person narratives of practitioners on the frontline of invasive species management in Australia with three case studies of community action for wild dog management across a range of geographical landscapes. The book offers readers a new understanding of how communities are formed in the context of managing different species, and how fundamental social and political processes can make or break landholders’ ability to manage invasive species. Using narrative analysis of practitioner profiles and community groups, drawing lessons from real-world practices, and employing theories from community development, rural sociology and collective action, this book serves multiple functions: it offers a teaching tool, a valuable research contribution, and a practitioner’s field guide to pursuing effective community development work in connection with natural resource management, wildlife management and environmental governance.

Download or read book Invasion Ecology written by Julie L. Lockwood and published by John Wiley & Sons. This book was released on 2013-04-05 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Invasion Ecology provides a comprehensive and updated introduction to all aspects of biological invasion by non-native species. Highlighting important research findings associated with each stage of invasion, the book provides an overview of the invasion process from transportation patterns and causes of establishment success to ecological impacts, invader management, and post-invasion evolution. The authors have produced new chapters on predicting and preventing invasion, managing and eradicating invasive species, and invasion dynamics in a changing climate. Modern global trade and travel have led to unprecedented movement of non-native species by humans with unforeseen, interesting, and occasionally devastating consequences. Increasing recognition of the problems associated with invasion has led to a rapid growth in research into the dynamics of non-native species and their adverse effects on native biota and human economies. This book provides a synthesis of this fast growing field of research and is an essential text for undergraduate and graduate students in ecology and conservation management.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation strategies have pros and cons, from the political to the economic to the classic biological. The goal of the body of work presented here seeks to explore an important potential downside of a popular conservation strategy, with the ultimate goal of improving that strategy not denouncing it. Conservation linkages, or corridors, have been a popular tool for multiple decades, and they are intended to enable native plant and animal movement in our increasingly fragmented world. For as long as they have been lauded, they have also been debated and one point of contention in that ongoing debate is whether or not linkages will connect up the species or processes we do not want moving across our landscape. My dissertation research used invasive plant species as its focal "unwanted" in conservation linkages. I outline the underpinnings of this work through a conceptual model that ties together the major ideas that feed into this concern over invasive plants in linkages, drawing from invasion, landscape, and conservation ecology (Chapter 1). I examined the concepts introduced in my conceptual model via observational data collection in a replicated model linkage system in hedgerows of Northern Central Valley, California (Chapter 2) and in large-scale conservation linkages of Southern California (Chapter 3). Those two field-based projects expand upon major themes raised by my conceptual model. Chapter 1 functions as an introduction and guidance source for researchers and managers who may be concerned about invasive plants in their conservation linkage. I developed a conceptual model that delineates eight ways in which invasive plants may interact with conservation linkages. Each interaction type within the model has three main components: linkage, matrix, and focal species. I discuss key aspects of these components, including a) differentiating among matrix types, b) understanding edge effects within the linkages, and c) incorporating relevant invasive species' ecology (primarily dispersal ecology). This model will enhance landscape-level knowledge of invasion ecology and aid land managers in identifying and prioritizing research and management decisions in their conservation linkages. Chapter 2 takes some of the major concepts of Chapter 1 off the paper and into the field. Using a hedgerow network in California's northern Central Valley as the model linkage system, this chapter focuses on how entire invasive plant communities are affected by various landscape-level factors and what contributes to spatially-explicit differences in invasive plant distribution within any given hedgerow. In 31 hedgerows, I collected spatially-explicit invasive plant distribution data as well as data for variables in seven explanatory variables groups: environmental, historical, landscape, management, spatial, structural, and biological. To analyze this data I used a combination of canonical correspondence analysis (CCA), variance partitioning, and non-parametric tests. I found that hedgerow edges were more invaded than interiors, in both species numbers (richness) and abundance (cover), and that difference was likely due to decreased light availability in hedgerow interiors, due to shading. Community-level patterns were strongly associated with environmental, historical, structural and/or landscape explanatory variables. The type of matrix was a key correlative factor and interacted with species dispersal mode. These results will serve as a guide for designing and managing hedgerows in ways that minimize invasion by certain groups of non-native plants based on characteristics of key landscape variables. Chapter 3 takes the concepts of Chapter 1 and the questions of Chapter 2 and applies them in a larger geographic region that contains real-world conservation linkages. This chapter delves more into the effect of differing matrix types and edge effects (i.e. effects of increasing distance away from a linkage edge into the linkage interior). I collected field data on a suite of focal invasive plants of concern to land managers in eight large-scale conservation linkages in southern California. Richness and cover data were collected along edges and up to 200m into the interior of linkages, supplemented with data from the middle-interior of linkages and the connected habitat patches. Explanatory variables were grouped into the same seven categories as those of Chapter 2: historical, structural, landscape, matrix, linkage, biological, and spatial. Using the same analysis methods as above supplemented with mixed-model analysis and classification and regression trees (CART), I found that linkage-related variables consistently explained larger proportions of the data variation than variables in the other six categories. Matrix land-use type again had an influence on invasive plant patterns, and the type of matrix influenced the magnitude of edge effects. Differing dispersal modes only interacted with invasive plant patterns along linkage edges. As in Chapter 2, I included specific management recommendations for how to research and manage invasive plants in conservation linkage systems with similar habitat or matrix types.

Book excerpt: The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume addresses SDG 15, namely "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss" and contains the description of a range of terms, which allow a better understanding and foster knowledge. Concretely, the defined targets are: Ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements Promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally Combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world Ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and protect and prevent the extinction of threatened species Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products Introduce measures to prevent the introduction and significantly Reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species Integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities Editorial Board Alexandra Aragão, Desalegn Yayeh Ayal, Ayansina Ayanlade, Anabela Marisa Azul, Adriana Consorte-McCrea, Muhammad Farooq, Ana Catarina Luz, María P.
