High southern latitude island environments are unusual in having relatively low or, in some cases, no non-indigenous species (NIS). Here we describe the accidental transport and survivorship of moths (Lepidoptera, […]
A generation of people have now grown up thinking that shorelines strewn with anthropogenic artefacts is normal. Yet this pehnomenon is just a few decades old and aesthetics and beach […]
Polar shores probably represent the most dynamic and extremely disturbed environments on the globe. Nevertheless intense battles amongst sessile organisms for space are commonplace on hard substrata, mainly between fast-growing […]
High polar communities tend to be young because of the frequent and intense impact of ice (scour), so colonisation patterns are particularly important. Yet, despite a wealth of studies at […]
Organisms have travelled the Atlantic Ocean as neuston and have rafted on natural marine debris for millions of years. Shipping increased opportunities for marine organism travel mere thousands of years […]
The physiology of many organisms in many places varies with seasonality of environment characteristics. Polar marine environments are amongst the least and most seasonal. For example, sea temperature varies by
This paper presents preliminary relative sea level curves for the Marguerite Bay region and for the South Shetland Islands. The Marguerite Bay curve is constrained by both new and previously […]
The recent collapse of several Antarctic Peninsula ice shelves has been linked to rapid regional atmospheric warming during the twentieth century. New high-resolution lake sediment records of Holocene ice-shelf behavior […]
An updated compilation of published and new data of major-ion (Ca, Cl, K, Mg, Na, NO3, SO4) and methylsulfonate (MS) concentrations in snow from 520 Antarctic sites is provided by […]
Small metazoans such as marine nematodes are increasingly identified using both molecular and morphological techniques. Formalin is the preferred fixative for morphological analysis but specimens become unsuitable for molecular study […]
Non-destructive photographic techniques are valuable for surveying benthic epifauna in sensitive areas. Inherent in these techniques, however, are selectivity biases related to the scale at which surveys are conducted. Such […]
Recruitment is a principal factor determining the establishment, diversity and persistence of assemblages in marine benthic ecosystems. Despite considerable research in temperate and tropical latitudes, however, almost nothing is known […]
