Effects of sea ice cover on the swarming behaviour of Antarctic krill,Euphausia superba

first_imgMuch of the distribution range of Antarctic krill, Euphausia superba, is covered by permanent or seasonal sea ice. Sea ice extent has been implicated as a major factor affecting reproductive success of krill and krill dispersal, but little is known of the way in which ice cover may influence krill behaviour. This is largely because the under-ice environment is difficult to study. Ship-borne echosounders have, however, detected krill aggregations in midwater in ice-covered regions. We used 120-kHz echograms collected underway during three cruises that crossed ice-covered and adjacent open waters in the Bellingshausen, Weddell, and Scotia seas to compare morphological and next-neighbour characteristics of krill swarms within and without ice cover. No significant differences were detected between the horizontal and vertical extent of swarms or swarm next-neighbour distance in ice-covered or open waters. Distributions of swarm mid-depths did, however, differ significantly between ice-covered and open areas in all three seas, although the direction of difference was not the same in each instance: swarms in the Weddell and Scotia seas were generally shallower under ice than in open water, whereas in the Bellingshausen Sea the opposite prevailed.last_img read more

A decade after junta’s end, Myanmar military back in control

first_imgBANGKOK (AP) — The man installed by army leaders as Myanmar’s new president after Monday’s military coup is best known abroad for his role in the crackdown on 2007 pro-democracy protests. Myint Swe was the army-appointed vice president who was elevated after the military arrested civilian leader Aung San Suu Kyi and other leaders of her party and declared a one-year state of emergency. But while Myint Swe is president, the real power lies with the country’s top military commander, Senior Gen. Min Aung Hlaing. He has been commander of the armed forces since 2011 and is due to retire soon. That would clear the way for him to take a civilian leadership role if the junta holds elections as promised.last_img read more
