This research was an outgrowth of the arctic IBP project which  had focused mainly on small Arctic pond ecosystems on the Alaskan  Arctic coastal plain. It was thought desirable to study larger, deeper  lakes which contained fish to further generalizations developed during  the IBP study. \u003cbr\u003e  Initial research on Toolik Lake and the surrounding lakes and ponds  focused on process studies such as annual primary productivity of the  lake or the vertical migration patterns of the resident zooplankton.  In 1983 the philosophy of the research changed with the funding of a  more integrated programme. The fundamental question posed was whether  Arctic lake and stream ecosystems are regulated from the bottom up by  nutrient availability or from the top down by the density and activity  of top predators. \u003cbr\u003e  In 1987 the Toolik Lake area was designated an LTER (Long-Term  Ecological Research) site, one of 18 such sites throughout the United  States, Puerto Rico and the Antarctic. The research theme for the  Arctic LTER also focuses on the regulation of Arctic ecosystems,  whether regulation comes from the top down or bottom up. The Arctic  LTER also incorporates a terrestrial component as well as a lake and  stream component. \u003cbr\u003e\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2012-11-05\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9789401052061\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-94-011-2720-2\u003c\/p\u003e \u003cp\u003eDimensions: 260cm x195cm\u003c\/p\u003e \u003cp\u003ePages: 269\u003c\/p\u003e ","brand":"Springer","offers":[{"title":"Default Title","offer_id":44398563623052,"sku":"9789401052061","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9789401052061.jpg?v=1755437525","url":"https:\/\/lateknightbooks.com\/products\/9789401052061","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
