Abstract We used the walked-line transect method for estimating the density of cats and coefficients of variation of density estimates in 4 contrasted sites on the main island of Îles Kerguelen between 1998 and 2000. Density estimates varied from 0.44±0.15 cats per km2 to 2.42±0.23 cats per km2 according to site and period. Coefficient of variation of density estimates ranged from 11.92% to 34.76%. The line transect method was, therefore, an efficient method for monitoring the density of the… 

Genetic structure of the feral cat (Felis catus L.) introduced 50 years ago to a sub-Antarctic island

Overall data suggested that the cat population of the main island of the Kerguelen archipelago has probably reached carrying capacity, and genetic diversity was consistent with the introduction of a very small number of individuals followed by a demographic explosion of theCat population.

Movements and space use of feral cats in Kerguelen archipelago: a pilot study with GPS data

It is suggested that trapping for management of the population should yield the highest number of captures in the afternoon and before sunrise, when cats are more active, and the potential of using GPS to track feral cats in sub-Antarctic islands is demonstrated.

Linking genetic diversity and temporal fluctuations in population abundance of the introduced feral cat (Felis silvestris catus) on the Kerguelen archipelago

Natal dispersal and/or local recruitment, both facilitated by high juvenile survival when the adult population size is small, is proposed as the major demographic processes contributing to such an observed pattern.

The mating system of feral cats (Felis catus L.) in a sub-Antarctic environment

Investigation of the mating system of domestic cats living in a sub-Antarctic environment shows that kittens from the same litter were sired by only one male in the Kerguelen population, hypothesised that this pattern is the closest to that of the original environment of adaptation.

Diet of feral cats during the Scopoli’s shearwater breeding season on Linosa Island, Mediterranean Sea

The management of feral cats living in proximity of the seabird colony is strongly required, and the increase of “trap-neuter-release” (TNR) programmes is necessary in order to avoid uncontrolled gains in the cat population on Linosa Island.

Abundance and home ranges of feral cats in an urban conservancy where there is supplemental feeding: a case study from South Africa

ABSTRACT There is much debate surrounding the impact of feral cats (Felis catus) on wildlife. Conservancies are usually areas where indigenous flora and fauna are protected and aliens excluded or

The diet of feral cats at New Island, Falkland Islands, and impact on breeding seabirds

The diet of feral cats on New Island, Falkland Islands is studied through the analysis of 373 scats collected during the austral summers of 2004/2005 and 2005/2006, and it is conceivable that cats are having a positive impact on the prion population, a scenario predicted by general theoretical models.

The diet of feral cats (Felis catus L.) at five sites on the Grande Terre, Kerguelen archipelago

The diet of introduced feral cats on the Grande Terre, Kerguelen archipelago, is evaluated by analysing 149 scats from 5 sites, suggesting that cats had a strong impact on the native avifauna.

Grey petrel population on Campbell Island 14 years after rodent eradication

Abstract Populations of grey petrels have declined globally due to both incidental capture in commercial fisheries and predation by introduced mammals at breeding sites. In the New Zealand region,
