Botanical gardens and fish farming played a crucial role in dispersal and na…
Data analysis on extinct and living Picidae in Sicily and Calabria (Southern Italy).
2015
Some species of animals related to forest habitats have disappeared or greatly decreased in the first half of the last century.

The present study is a complete overview of records of extinct and still living Black Woodpecker Dryocopus martius, European green Woodpecker Picus viridis, Middle spotted Woodpecker Dendrocopos medius and Lesser spotted Woodpecker Dendrocopos minor in Sicily and Calabria (Southern Italy). This study was carried out to show that these woodpeckers, …
