Limnology - the study of inland waters - had its genesis in Europe about
the turn of the century. The studies of Fore1 on Lake Geneva were of
seminal value at this time. It prospered under the early guidance of
Thienemann, Naumann and Wesenberg-Lund in Europe and, soon transplanted,
of Birge and Juday in North America (to name just a few early spirits).
Now, liminology is a respectable scientific discipline taught at many
universities, and limnologists are recognized as important contributors
to our understanding of how this fragile spaceship functions. All this
acknowledged, it must also be acknowledged that limnology is not yet a
globally comprehensive science. To be sure, much is known about globally
applicable processes, and the structural elements of aquatic ecosystems
worldwide, but limnological emphases, interests and concerns remain
essentially European and North American in balance. Much is known about
lakes and rivers in less than one fifth of the world's land area
(northern temperature regions); rather little is known about inland
waters elsewhere.
