“…Some persistent or invasive mammals have been removed in conservation actions, though these actions themselves have further impacts (Micol & Jouventin, 1995 ;Myers et al, 2000;Bester et al, 2002;Courchamp et al, 2003). Further eradication programmes are under consideration (the removal of reindeer from South Georgia) or trial (rat eradication on some offshore islets of South Georgia).…”

Alien microbes, fungi, plants and animals occur on most of the sub-Antarctic islands and some parts of the Antarctic continent. These have arrived over approximately the last two centuries, coincident with human activity in the region. Introduction routes have varied, but are largely associated with movement of people and cargo in connection with industrial, national scientific program and tourist operations. The large majority of aliens are European in origin. They have both direct and indirect impacts on the functioning of speciespoor Antarctic ecosystems, in particular including substantial loss of local biodiversity and changes to ecosystem processes. With rapid climate change occurring in some parts of Antarctica, elevated numbers of introductions and enhanced success of colonization by aliens are likely, with consequent increases in impacts on ecosystems. Mitigation measures that will substantially reduce the risk of introductions to Antarctica and the sub-Antarctic must focus on reducing propagule loads on humans, and their food, cargo, and transport vessels.

“…The success also depends on the interactions between invaders and residents and studies have demonstrated that residents frequently dominate alien species (MASSOT et al 1994, MYERS et al 2000b. In Praia das Neves, L. lutzae is restricted to strips of sand that can reach 50ºC in the warmest hours of the day.…”

This article examines the results of the introduction into Praia das Neves, state of Espírito Santo, Brazil, of Liolaemus lutzae Mertens, 1938, a lizard species threatened with extinction. Since there are few studies that evaluate how species establish and adapt to new environments, it is useful to assess to what extent the introduction of a critically endangered species into an area similar to where it originally occurred can help reduce its decline in number of individuals and avoid its possible extinction. This study presents the first results of an ongoing monitoring survey set up after the experimental introduction. We analyze how the introduced population uses space and food and we compare these characteristics to that of the original population at Barra de Maricá, Rio de Janeiro state. We also compare morphological measurementss of specimens from both populations. Both make similar use of the microhabitat, but there are differences in their diets. We recommend that the introduced population, potential competitors, predators, parasites, and the habitat characteristics continue to be monitored, so as to insure that this species will not become a threat to Praia das Neves beach community.

“…Many conservation goals require tradeoffs where some entities are protected to the detriment of others. For instance, ensuring ecosystem persistence can require culling species [20]. Most intrinsic value proponents claim all species and ecosystems are intrinsically valuable, but offer little guidance about how considering their intrinsic value resolves such conflicts.…”
