    ..Corvids were found to be the most important nest predators. Lemmings appear to be accessible to the whole predator community which makes them particularly powerful drivers of food web dynamics. ..

    Trends Ecol Evol 23:79-86. 2008
    ..Thus, collapses of these cycles are also expected to imply collapses of important ecosystem functions, such as the pulsed flows of resources and disturbances...

    Rolf A Ims
    Department of Arctic and Marine Biology, University of Tromsø, N 9037 Tromsø, Norway
    Proc Natl Acad Sci U S A 108:1970-4. 2011
    ..The combination of continued climatic warming and dampened vole cycles is expected to further decrease the frequency, amplitude, and geographic range of lemming outbreaks in tundra ecosystems...

    ..We showed that local ecological knowledge is a valuable source of information about large-scale processes, which are difficult to study through direct biological investigations. ..
