摘要

The data base contains >6,700 references to the ecology of waterfowl (Anatidae)and their wetland habitats. The emphasis is on North American waterfowl, but other English-language publications that concern Holarctic species or address relations of general interest are included. The bibliographic data are in computer files that can be edited, updated, and searched using a microcomputer and data base management software. Analysis of the bibliographic records indicates that the average number of waterfowl publications appearing each year increased from 2 during 1900-09 to >250 during 1980-89. Growth of the literature was exponential through the 1970's the number of references doubling every 10-12 years. However, the rate of increase apparently slowed during the 1980's.
