“Quercirhiza tomentelloreticulata” + Quercus suber L.

open access: yes, 2008
“Quercirhiza tomentelloreticulata” ectomycorrhizae are characterized by monopodial pyramidal systems with brownish to greyish tips. The mantle exhibits plectenchymatous organization in all layers. Outer mantle layers consist of irregularly shaped hyphae with no discernible pattern alternating with areas star-like organized: the mantle surface bears a ...

Breeding in natural nesting sites can improve the resilience of local Lesser Kestrel (Falco naumanni) populations to environmental changes

open access: yesIbis, Volume 168, Issue 2, Page 465-478, April 2026.
The identification of key habitats of threatened species and of extrinsic environmental factors that influence their resilience to human‐induced environmental changes are the foundation for the definition of conservation objectives. Using the presence and numerical abundance data collected in a long‐term survey (2000–24) of breeding colonies of Lesser ...
