Status of Egyptian vulture (Neophron percnopterus) in Sicily.
2009
La población del buitre Neophron percnopterus en Sicilia se encuentra restringida a los sectores central y oeste de la isla. La población alcanzó cerca de 30 parejas durante el periodo entre 1970 y 1980, auque durante nuestro periodo de estudio (1990–2007), la población tuvo un tamaño promedio de sólo 7 ± 2 parejas más 2 ± 1 individuos no emparejados, con fluctuaciones considerables en los números. Las tasas reproductivas durante nuestro periodo de estudio (juvenil por pareja reproductiva y juvenil por nido exitoso) fueron típicas para una población europea, aunque la tasa de éxito de los nidos disminuyó y el abandono de nidos durante el período 2000–2007 fue el doble del registrado durante…

Living on the edge: assessing the extinction risk of critically endangered Bonelli’s eagle in Italy
2012
Background: The population of Bonelli’s eagle (Aquila fasciata) has declined drastically throughout its European range due to habitat degradation and unnatural elevated mortality. There are less than 1500 breeding pairs accounted for in Europe, and the species is currently catalogued as Critically Endangered in Italy, where the 22 territories of Sicily, represent nearly 95% of the entire Italian population. However, despite national and European conservation concerns, the species currently lacks a specific conservation plan, and no previous attempts to estimate the risk of extinction have been made. Methodology/Principal Findings: We incorporated the most updated demographic information ava…
Finding of a living population of Panopea glycimeris (Von Born, 1778) (Bivalvia; Hiatellidae) in Eastern Sicily (Mediterranean Sea)
2011
A consistent living population of Panopea glycimeris (von Born, 1778) was documented underwater along the eastern coast of Sicily. Twenty specimens were counted over an area of 1000 m(2), with an estimated total population of less than 300 individuals. The morphometric measurements of an adult specimen captured are provided. Proposals to adopt protection measures for this species are discussed.
COASTAL ACCESSIBILITY AS VULNERABILITY FACTOR FOR PATELLA ULYSSIPONENSIS GMELIN, 1791 IN A MEDITERRANEAN MPA
2023
Average density of Patella ulyssiponensis Gmelin, 1791 was correlated with costal accessibility and tourists’ density. The results highlighted that the accessibility could have a greater weight than the MPA regulation, in absence of patrolling, on the vulnerability of this sensitive species.
