Baleen whales are extreme capital breeders, capable of fasting for more than half a year while migrating thousands of kilometres and nursing rapidly growing offspring that quadruple in body size over the same period. To understand this energetic conundrum…
Plankton, a diverse group of aquatic organisms, make Earth livable, regulate aquatic life, and provide benefits to human societies such as access to clean water, food security, and well-being. They also support economies and inspire biotechnological innovations.
Antarctica has experienced major changes in temperature, wind speed and stratospheric ozone levels over the last 50 years. Whilst West Antarctica and the peninsula have shown rapid warming and consequent ecosystem change, East Antarctica appeared to be little impacted by climate warming…
1.Ecosystem change is predicted to become more prevalent with climate change. Widespread dieback of cushion plants and bryophytes in alpine fellfield on Macquarie Island may represent such change. Loss of the keystone endemic cushion plant, Azorella macquariensis…
Fuel spills in Antarctic waters are increasingly likely with the rise in shipping in the region related to tourism and research activities, both of which require and transport large quantities of fuel. While fuel dispersants are not currently used in the management of fuel spills in Antarctica…
It has been shown by Taguchi (2010) that QBO periods were longer and … amplitudes larger during periods of La Niña than during periods of El Niño during … the period 1953-2008. Garfinkel and Hartmann (2007)…
In response to several fuel spills on sub-Antarctic Macquarie Island associated with research station operations, the Australian Antarctic Division has initiated a 5-10 year plan to remediate the island’s contaminated sites using low cost in-situ techniques.
A total of 44 records of southern right whale mortalities and non-fatal anthropogenic interactions have been documented in Australia by … museums, wildlife agencies and researchers since 1950. Sixteen of the events involved whales that apparently survived.
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
ABSTRACT: Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern Hemisphere or to small cetaceans … (SC) worldwide…
In their Policy Forum review “Do the largest protected areas conserve whales or whalers?” (Science, 28 Jan 2006, p.525), Gerber and co-authors criticised the scientific basis of the International Whaling Commissions’ (IWC)…
