Categorias e critérios da EICAT da UICN : primeira edição
Como resposta a estas questões, foi desenvolvida uma classificação padronizada dos táxones exóticos, baseada na magnitude dos seus impactos ambientais. EICAT (Classificação do Impacto Ambiental de Táxones Exóticos) o trata-se de um método simples, objetivo e transparente para classificar táxones exóticos de acordo com a magnitude dos seus impactos prejudiciais para o ambiente nas áreas recetoras. Com base na evidência dos impactos causados nos táxones nativos nas áreas em que foram introduzidos, os táxones exóticos são classificados em uma de cinco categorias de impacto. Cada uma destas cinco categorias de impacto representa uma magnitude de impacto diferente, dependendo do nível de organização biológica (indivíduo, população ou comunidade) sobre a qual o impacto é exercido e da reversibilidade do mesmo.
Global strategy on invasive alien species
The spread of invasive alien species (IAS) is creating complex and far-reaching challenges that threaten both the natural biological riches of the earth and the well being of its citizens. Summarising key findings of the Phase I Synthesis Conference held in September 2000 in Cape Town, Republic of South Africa, this publication presents ten strategic responses that address how to mitigate the threats of IAS. Directed toward the decision-makers whose policies and practices are affecting the movement of species around the world, this strategy strives to provide a resource to increase awareness and provide policy advice.
The great reshuffling : human dimensions of invasive alien species
While the issue of invasive alien species (IAS) has important biological components, the human dimensions deserve much greater attention. Humans, with all their diversity of quirks, strengths, and weaknesses, are at the heart of the problem of IAS and, paradoxically, also at the heart of the solution. This compilation of papers delivered during a workshop on the human dimensions of the IAS problem, held in Cape Town, South Africa on 15-17 September 2000, covers some of the many causes, consequences and responses to this problem.
Categorías y criterios de la EICAT de la UICN : primera edición
Se ha elaborado una clasificación unificada de los taxones exóticos basada en la magnitud de su impacto ambiental (de aquí en adelante, la Clasificación del impacto ambiental de taxones exóticos, abreviada como EICAT por sus siglas en inglés) en respuesta a estas cuestiones. Se trata de un método sencillo, objetivo y transparente para clasificar taxones exóticos en cuanto a la magnitud de su impacto ambiental perjudicial en las zonas receptoras. Los taxones exóticos se clasifican en una de cinco categorías de impacto según los datos existentes sobre el impacto que han ocasionado en taxones autóctonos en su área de introducción. Cada una de estas cinco categorías de impacto representa una magnitud de impacto diferente, según el nivel de organización biológica (individuo, población o comunidad) sobre la que ejercen un impacto y la reversibilidad de dicho impacto.

More than 70% of the earth is covered by oceans and major seas and there are more than 1.6 million kilometres of coastline. Yet our marine world is under threat: the most insidious is the one posed by marine invasive species. This booklet does not present new or primary information, but rather a synthesis of current issues and trends, including several examples of some of the worst marine invasive species, their spread and impact. It is targeted at the general public to highlight an important but often overlooked issue, and to serve as a source of information and inspiration.
Manual of invasive alien species in the Eastern Mediterranean
Marine invasive species can have a disastrous impact on biodiversity, ecosystems, fisheries, human health, tourism and coastal development, and they can be extremely difficult and costly to control. This manual is about the most common invasive alien species (IAS) in the Eastern Mediterranean Sea, mostly originating from the Red Sea, creating socioeconomic and ecological impacts on various levels. The manual highlights the current situation of IAS in the Eastern Mediterranean, and mainly focuses on the management measures of IAS, existing legislations and action plans, mitigation measures and implementation of the controlling procedures with different aspects and practices among various disciplines and across regions. The manual is designed for a varied audience from Marine Protected Area (MPA) managers to local authorities, from scientists to non-governmental or-ganisations that are involved in the in the management of IAS.
The conservation status of freshwater species and habitats in Key Biodiversity Areas at the Douro river basin
This report presents the results of a broad assessment of freshwater diversity in the Douro river basin in Spain and Portugal. The Douro river basin is the largest of the Iberian Peninsula, and an ecological region of great value due to the high diversity of ecosystems and the number of species. A total of 14 sites, either identified as Key Biodiversity Areas (KBAs) or potential KBA sites, were surveyed for fish and macroinvertebrate species. More than 120 species were detected, with more than 10 species listed as threatened with extinction on the IUCN Red List of Threatened SpeciesTM.
IUCN EICAT categories and criteria : first edition
A unified classification of alien taxa based on the magnitude of their environmental impacts has been developed in response to these issues. EICAT (Environmental Impact Classification for Alien Taxa) is a simple, objective and transparent method for classifying alien taxa in terms of the magnitude of their detrimental environmental impacts in recipient areas. Based on evidence on the impacts they have been causing on native taxa in their introduced range, alien taxa are classified into one of five impact categories. Each of these five impact categories represents a different impact magnitude, depending on the level of biological organisation of the native biota impacted (individual, population or community) and the reversibility of this impact.
Island invasives : scaling up to meet the challenge
The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017. The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size, global reach and of course financial cost. In the space of a few decades, the size of islands treated for invasive species has increased by five orders of magnitude – from a few hectares to over 100,000 ha or 1,000 km2. Meanwhile, the diversity of species being tackled has increased, as has the range of countries now actively carrying out island restoration work. Inspired by pioneers from New Zealand and Australia, principally, today the movement has spread to islands in all oceans and off all continents. This expansion has been informed by, and has in turn produced, growing experience in all aspects of this field, from non-target impacts to ecological responses to factors affecting eradication success. A major aim of publishing these Proceedings is to inform people who are, or will in the future be, planning new projects to free islands of invasive species. Regardless of its location or the target species involved, each successive operation builds on the experience of those who have gone before, and the papers in this volume represent an invaluable wealth of such experience.
