Il progetto per la conservazione dell'architettura storica nelle tesi di laurea di restauro
2017
La trasmissione dei valori, per la conservazione dell’architettura, della città storica e del paesaggio, o delle testimonianze che con il tempo hanno assunto valore di documento delle civiltà che ci hanno preceduto, avviene per l’impegno dei docenti di Restauro dei Monumenti. Dai principi condivisi scaturisce una specifica metodica che desidera assicurare per questa generazione, ma soprattutto per quelle che ci seguiranno, il mantenimento del patrimonio architettonico e ambientale, quale lascito collettivo da tramandare nei secoli. Nel saggio s’indaga lo strumento, fondamentale della didattica del Restauro dei Monumenti, rappresentato dalle tesi di laurea di Restauro, così come si è andato …
High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…
2018
[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …
Red list of threatened vascular plants in Italy
2021
Italy has a rich natural heritage, which is dangerously under pressure. In recent years, there is an increased awareness of the crucial role of plants in ecosystem functioning and in providing ecosystem services. Consequently, an updated Red List of the Italian vascular flora was compiled in this work, at the request of the Ministry for Environment, Land and Sea Protection, with the scientific support of the Italian Botanical Society. The IUCN Red List criteria were applied to 2,430 Italian native vascular plant taxa to assess their current extinction risk and to highlight the major threats affecting the Italian flora. Our results revealed that 54 taxa (2.2% of the assessed taxa) are extinc…
IDPlanT: the Italian database of plant translocation
2021
IDPlanT is the Italian Database of Plant Translocation, an initiative of the Nature Conservation Working Group of the Italian Botanical Society. IDPlanT currently includes 185 plant translocations. The establishment of a national database on plant translocation is a key step forward in data sharing and techniques improvement in this field of plant conservation. Supplemental data for this article is available online at https://doi.org/10.1080/11263504.2021.1985004.
Verifying the predicted risk of extinction based on ecological characteristics
2021
Red List status of species should reflect species extinction risk. Because data are limited and species response has a time lag, species may be threatened by extinction even if they are not Red‐Listed. The ability to predict species risk of extinction from ecological characteristics holds promises for proactively targeting conservation measures to species at high risk. In 2005, the risk of extinction from ecological characteristics was predicted for 81 species of Finnish butterflies. Now, after 15 years and two additional national Red List assessments, these predictions are verified. Species with a higher risk of extinction according to the original ecological extinction risk rank (EERR) ha…
Implementation of IUCN criteria for the definition of the Red List of Ecosystems in Italy, Plant Biosystems.
2020
The present work is aimed at presenting the data, methods and criteria that are being used for the assessment of ecosystem collapse risk in Italy.
Long-Term Data Reveal the Associations of the Egg Quality With Abiotic Factors and Female Traits in the Baltic Herring Under Variable Environmental C…
2021
In fish, the lipid resources of the female form a link between the environment and progeny, contributing to the contents of the egg yolk. Variation of the environmental conditions is therefore expected to affect the egg quality via maternal pathways, reflecting the female’s response to the environmental factors before spawning. We investigated the content of lipids and thyroid hormones in the ovary and eggs of the Baltic herring during 1988–2019, when salinity of the Baltic Sea first declined and then stabilized to a lower level, and winters varied between severe and mild. The total lipid resources of spawning females decreased by 40–50% during the study, and the ovarian lipid concentration…
Sulla didattica del restauro dei monumenti in Italia nell'ultimo venticinquennio del Novecento
2013
Certamente l’attuale stato della didattica del Restauro dei Monumenti, nelle sedi universitarie in Italia, è anche il frutto del dibattito che coinvolse i docenti dell’area, nel periodo compreso fra il 1975 e la fine del XX secolo. Il saggio indaga il fecondo dibattito che proprio in quegli anni si sviluppò, grazie soprattutto all’impegno di Roberto di Stefano. Lo studioso, infatti, contribuì in maniera incisiva alla promozione di incontri periodici e dei contenuti da assegnare alla disciplina Restauro dei monumenti e per lo sviluppo della formazione degli operatori della conservazione del patrimonio culturale, in particolare architettonico e ambientale dell’Italia. Importante risulta pure …
Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
Semi-natural habitats in boreal Europe: a rise of a social-ecological research agenda
2021
The European continent contains substantial areas of semi-natural habitats, mostly grasslands, which are among the most endangered habitats in Europe. Their continued existence depends on some form of human activity, for either production or conservation purposes, or both. We examined the share of semi-natural grasslands within the general grassland areas in boreal Europe. We reviewed research literature across the region to compile evidence on semi-natural grasslands and other semi-natural habitats, such as wooded pastures, in respect to a range of topics such as ecology, land-use change, socioeconomics, and production. We also explored drivers of the research agenda and outlined future re…
