In-Depth Information
could provide additional information that might be relevant to assessing introduc-
tion rates and pathways at a local level. For the same reason, I have not included
personal communication of unpublished introduction or naturalization events - they
simply cannot be captured comprehensively at a global scale. Finally, I have made
no sustained attempt to capture the gray literature of government reports. The rela-
tively few exceptions I've made to this rule are for studies that have been repeatedly
cited in the literature, are not too difficult to obtain, and provide information not
available in the published literature. I believe most of these exceptions are of
reports coming from Australia or the United States. Again, interested researchers
are likely to find it productive to pursue such reports at their local level.
A note on bibliographic completeness: this published bibliography includes
> 4,000 literature citations and a brief perusal of the journal titles will indicate the
wide range of sources involved. Every effort was made to make this bibliography
as complete as possible, given the constraint that I actually see the article (or have
a translation provided by a native speaker) myself. This criterion has required me
to exclude ca. 70 additional references that I have been unable to find in any library
in the United States, Australia, or at the British Museum (Natural History), or to
obtain directly from the printer overseas. Most of these unavailable citations derive
from the European or Japanese literature (some of these are cited in Lever, 2003)
and to note that they are in obscure, difficult-to-obtain regional journals would be
an understatement. The important point is that the interested researcher may not
find every relevant citation for an introduction included in this bibliography, but
they should be able to use the citations so provided to trace back and find the addi-
tional missing citations on their own, should they so desire.
Despite my best efforts to avoid them, I have every confidence that some errors
and inconsistencies will remain in this database. I hope they will be sufficiently rare
that the overall usefulness of the final product is not thereby compromised. I can
only apologize for these in advance and note that I welcome learning of mistakes
or overlooked literature that I can use to update or correct the database.
