Organic invaders signify one of many basic threats to the upkeep of world biodiversity, human health and wellbeing, and the good fortune of human fiscal companies. the ongoing globalization of our society guarantees that the necessity to comprehend the method of organic invasion will in simple terms raise sooner or later. there's additionally a becoming attractiveness that the examine of organic invaders presents a different perception into simple questions in ecology and evolution.
The examine of unique birds has had a very lengthy heritage and has come to symbolize a desirable intersection among the research of organic invasions, avian conservation biology, and easy rules of ecology and evolution. Avian Invasions summarizes and synthesizes this certain historic list and unravels the insights that the research of unique birds brings to all 3 of those examine strands. It contains chapters at the famous contributions of unique poultry examine to ecological technology, and at the post-establishment evolution of brought poultry populations. the result's the main complete photograph but of the invasion process.
Avian Invasions is aimed toward expert avian biologists and ornithologists in addition to graduate scholars of avian ecology, evolution and conservation. It additionally appeals to a extra basic viewers of invasion ecologists.

26 The Study of Exotic Birds There is one last point that we think needs to be made before we proceed to the main body of the book. , Lawton 1999; Hubbell 2001; Brown, et al. 2003; Chave 2004; Simberloﬀ 2004; Gaston and Chown 2005; West and Brown 2005). Exotic species are pervasive, and studying their evolutionary ecology and the consequences of their successful establishment is one way in which an understanding of these processes may be advanced. The invasion process itself is also of intrinsic theoretical and practical interest, in terms of understanding the ways in which species spread, and how the likelihood of such spread might be reduced in certain cases.

The larger than expected native range sizes of introduced bird species suggests that widespread species are more likely to be entrained in the invasion process. However, the inﬂuence of range size on the probability of introduction may be confounded with an eﬀect of population size. , Gaston and Blackburn 2000; Blackburn, et al. 2006). The inﬂuence of range size on introduction probability in wildfowl is greatly reduced when controlling for population size. Multivariate analysis suggests that large population size and large body size are the best predictors, of those tested to date, of introduction probability in wildfowl (Blackburn and Duncan 2001b).
