    The Southern Ocean is the fourth largest ocean in the world, it sustains a wide variety of marine life and plays a significant role in the global climate. No legal definition of the Southern Ocean exists, although there are biological and physical boundaries. Various human activities, such as science, tourism, bioprospecting and fishing have been identified. They pose environmental and legislative challenges to the Southern Ocean which have not yet been fully resolved. Climate change, which is often neglected as a result of human activity, is also interfering with the marine ecosystem. The current shortcomings in regulating these activities have been identified and recommendations have been made in order to protect the future of the Southern Ocean.

  • The Southern Ocean and the Patagonian Toothfish

    Extensive fishing industry is occurring in the area of the world known as the Southern Ocean (Kock et al., 2006). One of the main targets of this industry is Dissostichus eleginoides, commonly known as the Patagonian toothfish, or Chilean Sea Bass. Toothfish can commonly be found in the Southern Ocean and around Antarctica (Laptikhovsky et al., 2006). Toothfish are fished commercially for use in the food industry and it is known as a delicacy in some countries. It is a profitable market, as it is extremely viable with toothfish reaching high prices on legal and illegal markets (Lugten, 1997). Illegal fishing above, and beyond the established quota has led to this fish species becoming quite prominent due to sustainability issues and the regulation of fishing in the Southern Ocean (Vidas, 2000).

  • Lichen Life in Antarctica: A review on growth and environmental adaptation of Lichens

    Antarctica is a harsh environment with very little vegetation. The Antarctic continent and the surrounding areas can be divided into two or three general regions. Most often the continental area of Antarctica is identified,  with the Antarctic Peninsula being included as the maritime Antarctic due to oceanic influences (Lindsay, 1978; Sancho and Pintado, 2004). Usually a third area is also identified as being separate from the maritime antarctic, the sub antarctic (Robinson et al., 2003). The focus of this review is the continental and maritime regions. There are only two native flowering plants in Antarctica, with the terrestrial vegetation being primarily composed of cryptograms. Lichen are the most species rich, with 350 species   currently described (Kappen, 2000; Robinson et al., 2003). However, there is some debate about this total, depending on classifications, with a more conservative total also being put forward (Lindsay, 1978).
