Population dynamics of newly introduced species: Do newly introduced species present a separate problem?

Report to Annual Meeting
D. F. Hobbs  

[First paragraph(s)...]
It is intended to suggest that there are grounds for the separate consideration of the dynamics of newly introduced species, and further, that there is a need for closer research interest in the dynamics of new populations These aspects are dealt with in general terms.
There is little evidence in the literature to suggest that newly introduced species possess any special problems in population dynamics. In Allee's "Principles of Animal Ecology" and in recent studies by both Solomon (1949) and Haldane (1953) on natural regulation of animal populations, little distinction is made between indigenous and introduced populations, between human and other populations, or between, except in the case of Solomon, the test-tube populations of Gause and other workers and populations in a natural state While it is not suggested that any serious student of populations could afford to limit his reading and thinking to populations of either type, it appears that there could be dangers in failing to appreciate certain differences which seem to warrant separate consideration of the dynamics of newly introduced populations. Some of the more important aspects are indicated in the table.
