What difference does the walrus make? / Jan Marcin Wȩsławski, Michał Malinga.

Title: What difference does the walrus make? / Jan Marcin Wȩsławski, Michał Malinga.
Author(s): Wȩsławski, Jan Marcin.
Malinga, Michał.
Date: 1997.
Publisher: Lublin, Poland: Maria Curie-Skłodowska University Press
In: Polar session. Dynamics of polar environment, Lublin, December 1996. (1997.),
Abstract: Article considers effects on pelagic food web of various extinctions of sea mammals, in particular walruses. Sensible figures lead to estimate that in 15th Cent. walruses would have eaten 50% of standing crop - obviously wrong. So: production of biomass was different then (possible in Little Ice Age), OR walruses took other food, including ringed seals and birds, OR there are "hot spots" with high density of biomass - easily missed in surveys.
