Body sizes of European mink (Mustela lutreola L.), polecat (M. Putorius L.) and American mink (M. Vison Schreber) were studied over a 10-year period in an area of north-eastern Belarus, before and after the invasion by American mink, and data are presented on interspecific interactions. On arrival in the study area American mink males were larger than males of European mink and polecat, and American mink females were larger than females of the other species. After arrival of the American mink its mean body size decreased, whilst the resident male and female European mink and female polecat increased as measured in absolute mass, length and relative mass. The observations suggest a strong character convergence most plausibly explained as a response to the invading exotic by the residents as well as in the invading species itself, whilst a divergence had been expected. There was no evidence to show whether these differences were genetically based. The body size data are consistent with the hypothesis that European mink, and to a lesser extent polecat, are responding to direct aggression from American mink (rather than merely competing for resources), with the smaller individual European mink being more likely to disappear first. We provide direct evidence for the aggressive nature of inter-specific relations from observations using radio-tracking: all observed inter-specific interactions were aggressive, significantly more so than intraspecific encounters, causing the European mink to flee, and several left the study area altogether. Implications for niche theory and for conservation management are discussed.

The musteloids are the most diverse super-family among carnivores, ranging from little known, exotic, and highly-endangered species to the popular and familiar, and include a large number of introduced invasives. They feature terrestrial, fossorial, arboreal, and aquatic members, ranging from tenacious predators to frugivorous omnivores, span weights from a 100g weasel to 30kg giant otters, and express a range of social behaviours from the highly gregarious to the fiercely solitary. Musteloids are the subjects of extensive cutting-edge research from phylogenetics to the evolution of sociality and through to the practical implications of disease epidemiology, introduced species management, and climate change. Their diversity and extensive biogeography inform a wide spectrum of ecological theory and conservation practice. The editors of this book have used their combined 90 years of experience working on the behaviour and ecology of wild musteloids to draw together a unique network of the world's most successful and knowledgeable experts. The book begins with nine review chapters covering hot topics in musteloid biology including evolution, disease, social communication, and management. These are followed by twenty extensive case studies providing a range of comprehensive geographic and taxonomic coverage. The final chapter synthesises what has been discussed in the book, and reflects on the different and diverse conservation needs of musteloids and the wealth of conservation lessons they offer. Biology and Conservation of Musteloids provides a conceptual framework for future research and applied conservation management that is suitable for graduate level students as well as professional researchers in musteloid and carnivore ecology and conservation biology. It will also be of relevance and use to conservationists and wildlife managers.

This monograph is about predation in vertebrate animal community. The studies were done in the seminatural terrains with transitional mixed forest within the European forest zone in Belarus. The result part was organised as a top-down flow: First, the community characteristics related to predators were estimated. I presented data on predator species richness, population density and biomass with special attention paid to the changes in predator species diversity occurred during the last two centuries and particularly in connection with the American mink and raccoon dog naturalization. Then, the main features of predator food niches were given, and the structure of various predator guilds and size structure in predators were analysed. The next part of the monograph was devoted to examining of community-important factors acting in semi-natural terrains. Such factors affected either the whole community or its marked fragment. The last quite a large part of the monograph consisted of many chapters which present more or less essential results on different predator species, and stresses hot questions of their population ecology.

The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.

Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.

The introduction of alien species can upset ecosystems and have been identified as the second main cause of species extinction at a global level after habitat loss or deterioration. This publication sets out a European strategy to address this issue, developed in the framework of the Bern Convention and in line with guidelines adopted in 2002 on biological diversity. This strategy seeks to encourage the implementation of co-ordinated measures in all European states which are designed to prevent or minimise adverse impacts of non-native species on native biological diversity.

The target species of this thesis, the European mink (Mustela lutreola) and the American mink (Neovison vison), are considered respectively as one of the most threatened carnivores and as one of the worst invaders in Europe. Both species colonized the Iberian Peninsula very recently: the European mink entered from France in the 1950s and colonized the rivers basins of the Northeastern Spain, and the American mink was introduced in the 1950s through fur farming and is currently found in six different populations throughout the Northern half of the Peninsula. In the Iberian Peninsula, most analyses focused on conservation and management of the European and the American mink in the last two decades are at local-scale, using data collected over small areas inside their range of distribution. In this thesis, we explored the two mink species interaction, occupancy, abundance and potential distribution over their entire range of distribution in the Iberian Peninsula, in order to provide sound basis to guide conservation and management actions. We used data from live-trapping surveys conducted between 2000 and 2011 as part of the European mink conservation plan and the American mink control plan. Moreover, we collected presence data of the historical distribution of the European mink all over Europe and presence data of the American mink in the native (North America) and the invaded (Europe) ranges. We applied three different statistical techniques to analyze the data: Occupancy Models, N-mixture Models and Species Distribution Models. We provided evidences of a large-scale competitive exclusion of the native species by the invasive mink, and we found a negative trend in the abundance of the critically endangered mink over the last fifteen years. We produced a spatial prediction of the potential expansion of the American mink in the Iberian Peninsula, demonstrating that the species could colonize river basins of the entire Peninsula. Finally, we analyzed the overlap of the two mink species' potential distribution in the Iberian Peninsula, in order to identify priority conservation areas for the European mink. Overall, from our analysis emerged that a better coordination between local policies as well as a greater constancy in monitoring and controlling the American mink population is imperative to improve the conservation strategy of the European mink in Spain.

Large predators are among the most threatened species on the planet and ways of conserving them in the face of increasing human populations and associated resource requirements are becoming critical. This book draws upon the experiences of some of the world’s foremost large carnivore specialists to discuss the numerous issues associated reintroducing large predators back into their natural habitats. Reviews of internationally renowned reintroduction programs for wolves, European lynx and African wild dog reveal the successes and failures of these actions. Experts on tigers, snow leopards and jaguars contend that there are other conservation options of higher priority that will ensure their security in the long-term. Other experts discuss more theoretical aspects such as whether we know enough about these species to be able to predict their behavioural or ecological response to the reintroduction process. Social, economic, political and genetic considerations are also addressed.
