Growth and life history traits of introduced pumpkinseed (Lepomis gibbosus) in Europe, and the relevance to its potential invasiveness

摘要: The North American centrarchid, pumpkinseed Lepomis gibbosus (Linnaeus), is a good example of how the life history traits and biogeographical patterns growth can vary in populations introduced species, facilitating establishment new novel environments. Introduced into Europe from America late 19th century (Maes 1898), now established at least 28 countries Asia Minor (Fig. 1). Scientific interest species began early (e.g. Kunstler 1908, Roule 1931), but studies (i.e. papers with either Latin or common names, pumpkinseed, sunfish, title) only really mid-20th 2). output rose to about one publication per year 1970s, though half these were laboratory experiments on
