Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

open access: yesAgricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Understanding the Type 2 Immunity: An Evolving View Beyond Allergic Diseases

open access: yesAllergy, EarlyView.
ABSTRACT Type 2 (T2) immunity is classically associated with defense against helminths and environmental threats, from a physiological perspective, and with allergies and eosinophilic inflammatory diseases, in a pathological sense. However, growing evidence reveals that T2 pathways also support other essential homeostatic functions, including tissue ...
