Environmental drivers influencing the ambrosia beetle community: The primary role of geographic and climatic drivers in chestnut‐growing areas

open access: yesAgricultural and Forest Entomology, EarlyView.
Ethanol‐baited traps were placed in cultivated chestnut orchards (a) and mixed environments with assorted tree composition (b), over a 2‐year monitoring period in two valleys (NW Italy). A total of 118,286 ambrosia beetles was collected, representing six species.

Visible Foliar Injury and Physiological Responses to Ozone in Italian Provenances of Fraxinus excelsior and F. ornus

open access: yesThe Scientific World Journal, 2007
We compared leaf visible injury and physiological responses (gas exchange and chlorophyll a fluorescence) to high O3 exposure (150 nmol mol–1 h, 8 h day–1, 35–40 days) of two woody species of the same genus with different ecological features: the ...

Redefining ecosystem integrity for an Anthropocene biosphere: a process‐ and lineage‐based framework for restoration

open access: yesRestoration Ecology, EarlyView.
Restoration increasingly operates in rapidly transforming landscapes shaped by human‐driven global change, where historical reference states no longer represent achievable or even desirable targets. Yet, ecological restoration and conservation management still rely on composition‐based definitions of ecosystem integrity that assume stable reference ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1572-1587, June 2026.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Potential alternative tree species to Fraxinus excelsior in European forests

open access: yesFrontiers in Forests and Global Change, 2023
Common ash (Fraxinus excelsior L.) is a keystone tree species in Europe. However, since the 1990s, this species has been experiencing widespread decline and mortality due to ash dieback [Hymenoscyphus fraxineus (T.
