Genetic variability in Peregrine falcon populations of the Western Palaearctic region
2018
We analyzed variation in ten polymorphic microsatellites and a portion of cytochrome b mitochondrial DNA in 4 populations of the Peregrine falcon (Falco peregrinus). living in northern and southern Italy. Spain and Czech Republic to assess species diversity in the poorly investigated Western Palearctic region. The Spanish population lives in the contact zone between F. peregrinus peregrinus and F. p. brookei. both the northern Italian and the Czech populations live within the range of F. p. peregrinus and the southern Italian is within the F. p. brookei. We added to our cytochrome b sequence dataset comprising 81 samples. previously published mitochondrial DNA sequences (n = 31) of English …
IL FALCO PELLEGRINO (Falco peregrinus) IN SICILIA
2021
having doubled in number during the period 1978-2006, the population of the Peregrine Falcon Falco peregrinus living in Sicily currently seems to be stable, and has very probably reached the carrying capacity at the current ecological conditions of the insular ecosystems. A continuous standardized census (2010-2019) estimated at least 257 pairs scattered across the main island, plus some 13-15 pairs living on the small islands around Sicily. The population is not randomly distributed, but rather it is concentrated in all the suitable habitats of the island, nesting in either small crags or large cliffs from sea level to 1,424 m asl; it is rarer in the north-eastern corner (Peloritani, Nebro…
Sistematica del Falco pellegrino (Falco peregrinus) in Italia
2021
Validated data and published studies indicate that four subspecies are present in continental Italy and its surrounding islands. Two of these subspecies (F. p. peregrinus and F. p. brookei) represent breeding populations, while the other two (F. p. calidus and F. p. pelegrinoides) winter and migrate in the country. Indeed, the European subspecies (F. p. peregrinus) has the most intriguing status, as it can both breed and winter. The exact range of the breeding population is not well-defined - it probably occurs in alpine and pre-alpine areas, perhaps reaching the Apennines of central Italy. Individuals originating from northern European countries in autumn and winter certainly implement thi…
Factors affecting the diet of Peregrine Falcon in Italy
2016
The diet of top predators can provide useful information on phenology and abundance of their prey. The cosmopolitan and specialist Peregrine Falcon (Falco peregrinus) is an ideal model to assess whether food changes have occurred in the long-term. In this contribution, we reviewed all available literature on Peregrine Falcon diet in Italy which contained 11 detailed datasets useful for our review, and also included analysis of pellets, collected at three breeding sites of Sicily during 2014 and 2015. These data allowed us to shed light on the Peregrine Falcon’s diet over the last forty years (1978-2015). We calculated the numerical and biomass percentage of the resident and not-resident pre…
