In its statutory authority (National Science Foundation Act of
1950, as amended), the NSF is directed to both initiate and support
basic scientific research. In its Ecology Program, one mode of
initiating research is to en courage the development of new ideas
through advisory workshops. The NSF is specifically directed to
strengthen our nation's research potential. In addition,
stimulating new approaches to research will continue to be
prominent in the coming years as federal attention is given to
increasing the innovativeness and competitiveness of the U. S. in
science and engineering. A decision to initiate a workshop does not
arise de novo in the Ecology Program. Rather, it emerges from panel
discussions, conversations with in vestigators at meetings or on
the phone, and from discussions between pro gram officers in the
Division of Biotic Systems and Resources. This workshop was
developed to provide advice to the NSF and the lim nological
community. Some NSF perceptions on future funding for ecolog ical
research on lake communities are presented here. Researchers often
mentioned a paucity of innovative lake ecology at the community
level. This perception was accompanied by a certain frustration
since lakes probably have the best empirical data base of any
natural environment and should continue to lead in the development
of ecological concepts. Members of NSF advisory panels sometimes
expressed similar concerns during consid eration of proposals for
lake research."

The Princeton Guide to Ecology is a concise, authoritative
one-volume reference to the field's major subjects and key
concepts. Edited by eminent ecologist Simon Levin, with
contributions from an international team of leading ecologists, the
book contains more than ninety clear, accurate, and up-to-date
articles on the most important topics within seven major areas:
autecology, population ecology, communities and ecosystems,
landscapes and the biosphere, conservation biology, ecosystem
services, and biosphere management. Complete with more than 200
illustrations (including sixteen pages in color), a glossary of key
terms, a chronology of milestones in the field, suggestions for
further reading on each topic, and an index, this is an essential
volume for undergraduate and graduate students, research
ecologists, scientists in related fields, policymakers, and anyone
else with a serious interest in ecology. * Explains key topics in

The papers included in this readings text were selected and are introduced by the authors of Ecology as examples of excellent and insightful research that greatly contributes to our grasp and exploration of ecological questions. These studies span the range of ecological perspectives and are significant reading for every student in the life sciences.
In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with paleolimnological studies, simulation modeling, and small-scale enclosure experiments. Contributors describe consequences of predator-prey interactions, behavioral responses of fishes, diel vertical migration of zooplankton, plankton community change, primary production, nutrient cycling and microbial processes. Paleolimnological techniques enable the reconstruction of trophic interactions from past decades. Prospects for analyzing the interaction of food web structure and nutrient input in lakes are explored.
Fluctuations in fish populations in lakes can cascade through food
webs to alter nutrient cycling, algal biomass and primary
production. Trophic cascades may interact with nutrients and
physical factors to explain most of the variance in lake ecosystem
process rates. In this 1993 book, a multidisciplinary research team
tests this idea by manipulating whole lakes experimentally, and
coordinating this with palaeolimnological studies, simulation
modelling, and small-scale enclosure experiments. Consequences of
predator-prey interactions, behavioural responses of fishes, diel
vertical migration of zooplankton, plankton community change,
primary production, nutrient cycling and microbial processes are
described. Palaeolimnological techniques enable the reconstruction
of trophic interactions from past decades. Prospects for analysing
the interaction of food web structure and nutrient input in lakes
are explored.
