Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities. [PDF]

J Biogeogr, 2022
Abstract Aim Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research ...

Monitoraggio del cinipede galligeno (Dryocosmus kuriphilus) in cedui di castagno (Castanea sativa) mediante metodi integrati di telerilevamento e dendrocronologia.

, 2019
La vespa cinipide del castagno (Dryocosmus kuriphilus Yasumatsu) ha colonizzato tutti i castagneti italiani ed europei dai primi anni 2000. La parasitizzazione dell’insetto a carico delle gemme e il successivo sviluppo di galle sui germogli primaverili, conducono a una progressiva perdita di importanti porzioni dell’apparato fotosintetico (fino al 70%).

Hydroclimate and ENSO Variability Recorded by Oxygen Isotopes From Tree Rings in the South American Altiplano

Geophysical Research Letters, Volume 49, Issue 4, 28 February 2022., 2022
Abstract Hydroclimate variability in tropical South America is strongly regulated by the South American Summer Monsoon (SASM). However, past precipitation changes are poorly constrained due to limited observations and high‐resolution paleoproxies.
