Abstract

Abstract Colonial waterbirds, a major biodiversity element occurring in the core of ultra-anthropized Europe, are ideal indicators of the wellness of inland wetlands. Nonetheless, there is a critical knowledge gap in their trend and population status. We present an uninterrupted 47 years-long dataset of the breeding populations of 12 species of colonial waterbirds (Ardeidae, Phalacrocoracidae, Plataleidae, Threskiornitidae) throughout a 58,000 km2 agricultural region in the higher Po basin (NW Italy). A trained team of collaborators censused with standardized field techniques the number of nests of each species at 419 colonies in the 1972–2018 period, summing up a total of 236,316 records. Data cleaning and standardization were performed for each census year, ensuring robust and consistent data. This dataset is among the largest ever collected for a guild of European vertebrates. It has already been used to describe the factors influencing population trends, and still offers opportunities to explore a wide range of key ecological processes such as biological invasions, global change consequences and biodiversity impact of agricultural practices.

Abstract

Riassunto - Scoperta di popolazioni isolate di Phengaris alcon e Melitaea diamina nella Pianura Padana centrale (Italia) ( Lepidoptera Rhopalocera ). all’interno del Parco del Mincio (Mantova, lombardia) sono state scoperte popolazioni di Melitaea diamina (Lang, 1789) e Phengaris alcon ([Denis & Schiffermueller], 1775) ( lepidoptera rhopalocera ), rispettivamente nell’anno 2008 e 2010. entrambe le specie non sono note per la Pianura Padana, e le popolazioni piu vicine conosciute si trovano a 170 e 50 km, rispettivamente per P. alcon e M. diamina . Durante l’anno 2011 sono state svolte ulteriori indagini su queste nuove popolazioni. entrambe le specie sono state riscontrate esclusivamente in prati umidi, di cui sono considerate specie tipiche. le nuove popolazioni dovranno essere protette, garantendo il mantenimento in futuro dei prati umidi mediante sfalcio. Abstract - Populations of Melitaea diamina (Lang, 1789) and Phengaris alcon ([Denis & Schiffermueller], 1775) ( lepidoptera rhopalocera ) were discovered in the Mincio natural Park (Mantua province, lombardy) in the years 2008 and 2010, respectively. Both species had not been known from the central Po Plain and the closest populations are approximately 170 km and 50 km away for P. alcon and M. diamina , respectively. More data on the new populations were collected during the year 2011. Both species were exclusively found in wet meadows, for which they are considered typical. The newly discovered populations need to be protected by ensuring that the meadows will continue to be mown in the future.
