A global review of the impacts of invasive cats on island endangered vertebrates
Feral cats on islands are responsible for at least 14% global bird, mammal, and reptile extinctions and are the principal threat to almost 8% of critically endangered birds, mammals, and reptiles.
Is the yellow-legged gull a superabundantbird species in the Mediterranean? Impacton fauna and flora, conservation measuresand research priorities
From the point of view of fauna and flora conservation, the yellow-legged gull can, for the moment, be considered to be locally superabun dant.
Impacts of seabirds on plant and soil properties
This chapter discusses the common effects of seabirds on island soils and plant chemistry. It examines seabirddeposited nitrogen and phosphorus, commonly known as guano, and their effects in soils…

The broad range of taxa consumed by feral cats on islands suggests that they have the potential to impact almost any native species, even the smallest ones under several grams, that lack behavioral, morphological or life history adaptations to mammalian predators.
Feral Cats and Biodiversity Conservation: The Urgent Prioritization of Island Management
The role of feral cats in the context of the island biodiversity crisis is examined, by combining data from reviews of trophic studies, species conservation status reports, and eradication campaigns to identify priority islands where feral cat eradications are likely to be feasible and where cats are predicted to cause the next vertebrate extinctions.

The diet of a long-established feral cat population on a small Mediterranean island confirmed that feral cats are generalist predators, able to feed on a wide range of prey, however, only a few prey species formed the major part of its diet.
Effects of anthropogenic food resources on yellow-legged gull colony size on Mediterranean islands
The yellow-legged gull changes on the islands in the last two decades increased as availability in anthropogenic food resources increased near the colony (positive ΔK), and it is expected this region to sustain continuous species expansion in the future.
Feral Cats Felis catus Threaten the Endangered Endemic Barau's Petrel Pterodroma baraui at Reunion Island (Western Indian Ocean)
Results showed that Barau's Petrel were the most common prey of feral cats, followed by introduced rodents, which is particularly worrying given the high sensitivity of the population growth rate of a long-lived seabird to any additive mortality of adults.
Improving PCR detection of prey in molecular diet studies: importance of group‐specific primer set selection and extraction protocol performances
The results clearly indicate that the A260/A280 absorbance ratio, which varies between extraction protocols, is positively correlated to the number of PCR amplifications of each prey taxon.
Morphological versus acoustic analysis: what is the most efficient method for sexing yelkouan shearwaters Puffinus yelkouan?
Two methods for sexing yelkouan shearwaters are tested: the classical morphological method and a new acoustic method, which can be sexed with 100% accuracy by measuring FC.
