Acoustic estimates of krill abundance at South Georgia, 1981–1998
Abstract: Acoustic estimates of abundance of the Antarctic krill, Euphausia superba, at South ... a primary objective, and estimates derived for the first time here from acoustic data collected as a ... subsidiary during other studies of the pelagic ecosystem at South Georgia. Krill abundance at the island ... fluctuated widely from year to year over this time, ranging from?2 to? 150 gm-2 (wet weight). The 1982, 1991 ...

Status of krill target strength
Abstract: Empirical estimates for the target strength of krill are extracted from the literature ... cause of bias in single-animal measurements, namely thresholding. Theoretical estimates for the target ... strength are derived from the deformed-cylinder scattering model assuming specific sets of physical and ... orientational parameters, for which there is an empirical basis. The theoretical estimates show a non-monotonic ...

Competition-induced starvation drives large-scale population cycles in Antarctic krill
Abstract: Antarctic krill (Euphausia superba)—one of the most abundant animal species on Earth ... . Previous studies have postulated that the krill cycle is induced by periodic climatological factors, but ... , we identify intraspecific competition for food as the main driver of the krill cycle, while external ... that the cycle amplitude increases with reduction of krill loss rates. Thus, a decline of apex ...
