Available in PDF, EPUB and Kindle. Book excerpt: An intensive sampling of all ant species encountered on 6 Hawaiian Islands: Big Island, Maui, Oahu, Kauai, Molokai, and Lanai took place between 1988 and 1996. Species presence and absence was recorded at each site. Using remote sensing, variables were added insitu and used throughout my analysis. Species accumulation curves suggest that sampling was comprehensive. There is a significant trend between island area and species richness which validates the Theory of Island Biogeography for invasive species. Islands were found to be significantly nested by area, order, and tourism. Cluster analysis shows a link between elevation, land-use and island, and species presence. Predictive models can be built to predict spread of particular ant species as they continue toward equilibrium.

Download or read book Alien Species in North America and Hawaii written by George W. Cox and published by . This book was released on 1999-09 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is in the midst of an ecological explosion with devastating implications. Thousands of species of microbes, plants, and animals are being introduced, both deliberately and inadvertently, to new land areas, seas, and freshwaters. In many regions, these new colonists are running wild, disrupting the dynamics of ecosystems, pushing native species toward extinction, and causing billions of dollars in direct economic damages.Alien Species in North America and Hawaii provides a comprehensive overview of the invasive species phenomenon, examining the threats posed and the damage that has already been done to ecosystems across North America and Hawaii. George W. Cox considers both the biological theory underlying invasions and the potential and actual effects on ecosystems and human activities. His book offers a framework for understanding the problem and provides a detailed examination of species and regions. Specific chapters examine: North American invaders and their threats how exotic species are dispersed to new regions how physical and biotic features influence the establishment and spread of invasives patterns of exotic invasions, with separate chapters covering each of the ten most seriously invaded regions and ecosystems patterns of invasiveness exhibited by major groups of exotics the theory of invasive capability of alien species and the resistance of communities to invasion theoretical aspects of ecosystem impacts of invaders and the evolutionary interaction of invaders and natives management and public policy issuesAlien Species in North America and Hawaii offers for the first time an assessment and synthesis of the problem of invasive species in North American and Hawaiian ecosystems. Scientists, conservation professionals, policymakers, and anyone involved with the study and control of invasive species will find the book an essential guide and reference to one of the most serious and widespread threats to global biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.
Download or read book The Effects of Invasive Ants on Arthropod Species and Communities in the Hawaiian Islands written by Paul Daniel Krushelnycky and published by . This book was released on 2007 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are of interest both because they are causing extinctions worldwide and because they offer unique opportunities to study highly dynamic ecological processes. I examined ant invasions at five natural area sites in the Hawaiian Islands to better understand the factors that influence impacts on arthropod populations, species and communities. Ant invasion usually led to significant changes in overall arthropod community composition, particularly among endemic subsets of the communities. When compositional stability was measured as proportional change in richness, the best predictor of endemic community stability was endemic richness, with richer communities losing proportionately more species than species-poor communities. This relationship suggests that communities that had already lost many endemic species were resistant to further species loss, while more intact communities remained vulnerable to species loss upon ant invasion. Communities also underwent strong but idiosyncratic functional shifts as a result of ant invasion, both in terms of trophic structure and total arthropod biomass. There were no apparent relationships, however, between functional stability and community diversity or density measures.

Download or read book Alien Species and Evolution written by George W. Cox and published by Island Press. This book was released on 2013-04-10 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging information on the evolutionary changes that occur in plants, animals, and microbial organisms when they colonize new geographical areas, and on the evolutionary responses of the native species with which alien species interact. The book is broad in scope, exploring information across a wide variety of taxonomic groups, trophic levels, and geographic areas. It examines theoretical topics related to rapid evolutionary change and supports the emerging concept that species introduced to new physical and biotic environments are particularly prone to rapid evolution. The author draws on examples from all parts of the world and all major ecosystem types, and the variety of examples used gives considerable insight into the patterns of evolution that are likely to result from the massive introduction of species to new geographic regions that is currently occurring around the globe. Alien Species and Evolution is the only state-of-the-art review and synthesis available of this critically important topic, and is an essential work for anyone concerned with the new science of invasion biology or the threats posed by invasive species.
Download or read book Filters Along the Invasion Pathway written by Delayn Fritz and published by . This book was released on 2017 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive ants can have negative impacts around the world on natural ecosystems and horticultural industries. The invasion pathway is seldom studied in its full extent (from pre to post border) when considering taxa, mostly one specific part of the pathway is explored in great detail, as has been done with exotic ants establishing in New Zealand. Exotic ants are an excellent case study of invasive species in New Zealand; they are frequently intercepted entering New Zealand‘s border and there are excellent digitised location records from around New Zealand representing their spread. This study explores three stages of the invasion pathway for exotic ants in New Zealand : i) the pre-border transportation/vectoring stage, where the diversity, interception rates, and origins, of ant species and genera entering New Zealand were examined using border interception rates; ii) the establishment stage where a range of variables were modelled to examine why some species and genera overcome the barriers of establishment and why others cannot; and iii) the spread stage, where the variables used in the establishment stage were modelled to describe the spread rate of species, at both a micro and macro resolution, as well as determining which habitats are most likely to be invaded. Two datasets were compiled: i) border interception records obtained from the Ministry for Primary Industries and published literature to explore ants entering New Zealand as well as to predict exotic ant establishment; and ii) natural history collection records from entomology collections around New Zealand to determine the spread rates and habitation variables of exotic ants already established. For border interceptions, data contained 5932 records at the species level for 146 different species. Species diversity remained consistent over time, however, one species, Pheidole megacephala, dominated these records (20.4%), and twenty of the 146 species represented 90% of the records. Reproductive ability was the only variable to markedly change using information about the caste and type of interception, showing a marked decrease over time from 82% to 26%. Linear Discriminant Analyses correctly predicted the failure of a species to establish 87.2% of the time using the variables of hind tibia length, minimum temperature (of the most extreme global locality), mean temperature (of the most extreme global locality), and interception rate. However, this model only correctly predicted establishment 39% of the time. At the genus level, models were able to correctly predict establishment success at 76.4% and failure to establish at 78.9%. Two variables, interception rate and cold temperature tolerance (minimum temperature), were important predictor variables for the establishment phase significantly increased both minimum and maximum spread rates. Human-modified habitats had the highest occupancy of exotic ant species, with the highest number of records being found within urban environments. Both of these establishment variables were also significant factors at the spread phase. These results can be used in the augmentation of existing risk assessment or in the implementation of new risk assessment analyses and mitigation methods.

Available in PDF, EPUB and Kindle. Book excerpt: Ants have always fascinated the nature observer. Reports from ancient Egypt and Mesopotamia indicate that ants interested humans long ago. Myrmecology as a science had its beginning in the last century with great naturalists like Andre, Darwin, Emery, Escherich, Fabre, Fields, Forel, Janet, Karawaiew, McCook, Mayr, Smith, Wasmann and Wheeler. They studied ants as an interesting biological phenomenon, with little thought of the possible beneficial or detrimental effects ants could have on human activities (see Wheeler 1910 as an example). When Europeans began colonizing the New World, serious ant problems occurred. The first reports of pest ants came from Spanish and Portuguese officials of the fifteenth and sixteenth centuries in Trinidad, The West Indies, Central America and South America. Leaf-cutting ants were blamed for making agricultural development almost impossible in many areas. These ants, Atta and Acromyrmex species, are undoubtedly the first ants identified as pests and may be considered to have initiated interest and research in applied myrmecology (Mariconi 1970).

Book excerpt: Examining globally invasive alien birds, the first part of this book provides an account of 32 global avian invasive species (as listed by the Invasive Species Specialist Group, ISSG). It acts as a one stop reference volume; it assesses current invasive status for each bird species, including details of physical description, diet, introduction and invasion pathways, breeding behaviour, natural habitat. It also looks at the environmental impact of each species, as well as current and future control methods. Full colour photographs assist with species identification and global distribution maps give a visual representation of the current known distributions of these species. The second part of the book discusses the biogeographical aspects of avian invasions, highlighting current and emerging invasive species across different regions of the world. The third section considers the impact of invasive species on native communities, problems associated with invasive bird management and the use of citizen science in the study of invasive birds.
