Floral development of two alien species (Cerastium fontanum, Poa annua) were monitored through the summer of 2013/14 at three different altitudinal sites (coastal, hillside and plateau) on the North eastern end of sub-Antarctica Macquarie Island.
Numerous fuel spills associated with human activities in Antarctica have occurred and significant levels of petroleum hydrocarbon contamination have been reported near Antarctic stations.
Major stratospheric warmings (MSWs) are one of the most important phenomena of wintertime Arctic stratospheric variability. They consist of a warming of the Arctic stratosphere and a deceleration of the polar night jet…
Within the Pycnogonida, genetic studies have … revealed that Colossendeis megalonyx Hoek (Challenger … Report, Zoology, 3(X), 1–167, 1881), consists of a complex of … several cryptic or overlooked species.
Stressors associated with climate change, and contaminants resulting from the activities of humans, are affecting organisms and ecosystems worldwide. Until recently, the impacts of these stressors on marine ecosystems have largely been examined in isolation. However, with predicted climate change…
Stressors associated with global climate change and local human activities are affecting marine organisms worldwide. Stressors include changes in temperature, salinity and acidification, in addition to contaminants including metals and hydrocarbons.
Understanding the sensitivities of Antarctic organisms to metal exposure is essential when developing protective environmental quality criteria for Antarctica. This study takes a community based approach to determine the potential effects of metal contamination on coastal Antarctic zooplankton.
As zooplankton is an important food source for consumers, and a major source of recruits to the benthic community, impacts on sensitive zooplankton communities have the potential to significantly alter nearshore marine ecosystems in Antarctica.
Understanding the sensitivity of Antarctic organisms to metal exposure is essential … for developing Antarctic specific Environmental Guidelines to manage contamination risks. For … the first time…
As zooplankton is an important food source for consumers, and a major source of … recruits to the benthic community, impacts on sensitive zooplankton communities have the … potential to significantly alter nearshore marine ecosystems in Antarctica.
Manipulative field studies are useful for investigating cause–effect relationships between contamination and benthic community health. However…
Evaluating the demographic trends of marine top predators is critical to understanding the processes involved in the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical complexity of operating in … Antarctica, especially during winter…
The population size of emperor penguins at the land-based Taylor Glacier colony was monitored over 54 years from 1957 to 2010 by intermittent ground counts from 1957 to 1975 and annual photographic counts from 1988 to 2010 of males attending the colony in winter and chicks in early summer.
The ACCESS 1-0 and ACCESS 1.3 now have a set of 3 historical ensemble members which include the late 20th Century and early 21st Century (2020) simulations. Recently we have just completed a new set of experiments designed to investigate the impact of the perturbation in ozone since 1960.
Considerable progress in our understanding of the causes of polar stratospheric ozone loss has been made during the past two decades. However, model calculations are still limited by uncertainties in both chemical and dynamical factors.
Links between changes in the southern polar stratosphere and tropospheric climate have been identified in both modelling and observational studies, highlighting the importance of an accurate stratosphere in climate models. However…
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…

Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
This study aimed to describe the migratory distribution and behaviour of pygmy blue whales … that feed in the Perth Canyon region off the coast of Western Australia.
The origins and evolution of sub-Antarctic island floras are not well understood. In particular there is … uncertainty about the ages of the contemporary floras and the ultimate origins of the lineages they contain. Pringlea R. Br. (Brassicaceae)…
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
