✦ Synopsis

to be the principal mechanism through which generalized introduced predators and herbivores cause so much damage6. Interestingly, unlike many Pacfic islands, Guam has no introduced species of mongoose. Not only might these have acted as predators (though they are not arboreal), but mongooses dramatically reduce the densities of lizards (T. Case, unpublished). We can only speculate as to whether the presence of mongooses would have reduced the effect of Boiga or whether the mongooses themselves would have had a severe impact on the avifauna. As with other species introductions, this one can tell us about how communities work. it shows, first, how quickly a community can change when a species invades. The very speed of the extinctions will often make reconstructing events difficult or impossible. The reasons for the loss of Guam's forest birds would have been hard to understand had these changes occurred even 2 Savidae, J.A. (1987) Ecoloav68, 560-668 _. 3 van Rioer Ill. C.. van RiDer. S.G..
