Abstract (sommario):
Abstract The Pleistocene glacial period shaped the current genetic structure of numerous species. The last glacial dynamics has been proposed to have split the South American sea lion, Otaria flavescens, into two Evolutionarily Significant Units (ESUs), one on each side of the continent. However, previous studies have not provided genetic information on colonies found along 3000 km of coastline of the southernmost limit of the species distribution, where gene flow could occur. We conducted an exhaustive phylogeographical analysis of O. flavescens using a mtDNA marker, including, for the first time, data from colonies living south of latitude 45° S, in the Argentinian provinces of Santa Cruz and Tierra del Fuego. Our results indicated the presence of five Conservation Units across the distribution range of O. flavescens and suggest that the Patagonian population must have expanded about 150 000 BP. We found evidence for gene flow across the entire species range, supporting a scenario of secondary contact in Tierra del Fuego where representatives of the oldest lineages coexist. The presence of gene flow between oceans leads us to reject the assumption of complete reciprocal monophyly for mtDNA between the presumed ESUs, suggesting that the species constitutes a single Evolutionarily Significant Unit.

Abstract (sommario):
The objective of interest-groups is to influence policy. Conflict is inevitable when two or more interest-groups are in competition for scarce resources. It then becomes the responsibility of the state to accommodate or resolve the conflict. However, an additional complexity occurs if the state agencies are themselves undergoing transformation, as has recently occurred in South Africa.These issues are explored, using as a case-study the conflict that occurred between environmental interestgroups and a mining company over an application to dredge-mine the sand dunes that line the eastern shores of Lake St Lucia in Natal. The nature and objectives of these groups is discussed, and the role of the press in the controversy is analysed. The interests of black settlers who wish to return to their ancestral lands following the collapse of apartheid are shown to complicate further the dilemma that confronts state policymakers. The changing nature of the ‘decision environment’ in South Africa is addressed, and group theory is used to explain the relationship between state agencies and the mining, environmental, and black settler group, interests. Stages in the policy environment to match the modes of change over the period of political transformation in South Africa are identified by levels of conflict and ambiguity in a contingency model.

Abstract Mqoqi, M., Lipiński, M. R., and Salvanes, A. G. V. 2007. The ecology of Sepia australis (Cephalopoda: Sepiidae) along the south coast of South Africa. – ICES Journal of Marine Science, 64: 945–955. The influence of abiotic factors (depth, region, temperature, salinity, and oxygen) on the abundance of the cuttlefish Sepia australis was investigated using data from bottom-trawl stations occupied in April/May (austral winter) 1988 and August/September (austral spring) 2001 off South Africa' south coast. April/May survey data for 1999, 2003, and 2004, and August/September data for 2003 and 2004 were used to assess regional or depth-related patterns in abundance. Temperature differences in the two years mainly analysed influenced distribution and abundance significantly. Abundance increased eastwards in 2001 presumably because of a high-temperature anomaly stretching westwards (i.e. limiting the species abundance to the west), whereas abundance increased westwards in the more typical winters of 1988, 1999, 2003, and 2004. Abundance increased with depth in spring 2001, 2003, and 2004. Smaller sizes of mature males may indicate that they mature earlier than females. The main prey of all size groups and maturity stages was crustaceans, and there were no size- or maturity-related changes in diet. It appears that S. australis is an opportunistic feeder dependent on whatever prey of appropriate size is abundant at any time. However, the data show an array of patterns, some likely to be the result of biological flexibility in response to a changing environment. Other patterns are part of more stable, well-balanced ecological characteristics of the species.
