New insight into the Pleistocene deposits of Monte delle Piche, Rome, and remarks on the biochronology of Hippopotamus (Mammalia, Hippopotamidae) and Stephanorhinus etruscus (Mammalia, Rhinocerotidae) in Italy [PDF]

open access: yes, 2015
Several large mammal assemblages have been collected in the Roman basin since the XIX century, but they usually lack any stratigraphic datum or details about the fossiliferous localities. In this work, the stratigraphic provenance of large mammal remains

Spatio‐temporal species aggregations do not rule out interspecific competition in tree hollow spider assemblages Las agregaciones espaciotemporales entre especies no descartan la competencia interespecífica en los ensambles de arañas de las oquedades arbóreas

open access: yesEcological Entomology, Volume 49, Issue 1, Page 106-118, February 2024.
Abundance data reflects the reality of biological systems better than the presence/absence of data. Spatial species aggregations do not imply that interspecific competition is absent while spatial segregations do not mean that it is, considering species morphoecological traits and phenology.

Will they be back? A framework to guide rare macrophyte conservation decisions in lakes

open access: yesRestoration Ecology, Volume 32, Issue 1, January 2024.
Shallow lake restoration typically focusses on the re‐establishment of macrophytes. The likelihood of a species returning to a site is contingent on dispersal, proximity to propagule sources, and the on‐site propagule‐bank viability. We explore the potential of palaeoecological records in combination with botanical surveys and distribution maps, to ...
