Absolute zapovednost’ as an ethical model
2013
There is a substantial difference between protected areas and wildlife sanctuaries. The former are a rational answer to the current decline of biodiversity and, as such, they are widely accepted in our society; the latter respond to an ethical need, which is not very common so far. This is the reason why administrators and public opinion are reluctant to accept the non-usability of areas that, to be preserved, require maintenance, patrolling and monitoring costs. The challenge of increasing the consensus around wildlife sanctuaries goes far beyond the establishment of protected areas. It lies in making desirable a sober lifestyle, with general awareness of the environmental consequences of …
Dispersal ecology of deadwood organisms and connectivity conservation
2018
Limited knowledge of dispersal for most organisms hampers effective connectivity conservation in fragmented landscapes. In forest ecosystems, deadwood‐dependent organisms (i.e., saproxylics) are negatively affected by forest management and degradation globally. We reviewed empirically established dispersal ecology of saproxylic insects and fungi. We focused on direct studies (e.g., mark‐recapture, radiotelemetry), field experiments, and population genetic analyses. We found 2 somewhat opposite results. Based on direct methods and experiments, dispersal is limited to within a few kilometers, whereas genetic studies showed little genetic structure over tens of kilometers, which indicates long…

Pd2Au36(SR)(24) cluster: structure studies
2015
The location of the Pd atoms in Pd2Au36(SC2H4Ph)(24), is studied both experimentally and theoretically. X-ray photoelectron spectroscopy (XPS) indicates oxidized Pd atoms. Palladium K-edge extended X-ray absorption fine-structure (EXAFS) data clearly show Pd-S bonds, which is supported by far infrared spectroscopy and by comparing theoretical EXAFS spectra in R space and circular dichroism spectra of the staple, surface and core doped structures with experimental spectra.
Conservation status of the Italian flora under the 92/43/EEC ‘Habitats’ Directive
2021
The results of the 4th National Report for the Italian flora under the 92/43/EEC ‘Habitats’ Directive are presented. The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.
PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo
2022
I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…
Áreas protegidas e urbanização : o caso da APA da ilha do Combú, Belém-PA
2020
The paper seeks to answer two questions: what is the influence of the geographical location of the island of Combú in the metropolitan area of Belém, PA, and whether its current status as an Area of Environmental Protection (APA) has any impact on biodiversity and socioeconomic development? Similar to other riverside areas in the Amazon, Combú has a long history of involvement in the trade of extractive products. However, its geographical proximity to Belém and consequent access to markets made producers less dependent on intermediaries, while the ownership of resources was based on independent family units. Therefore, the dominant mode of caboclo extractivism, together with limited access …
