Hybridization selects for prime‐numbered life cycles in Magicicada: An individual‐based simulation model of a structured periodical cicada population

2020

Abstract We investigate competition between separate periodical cicada populations each possessing different life‐cycle lengths. We build an individual‐based model to simulate the cicada life cycle and allow random migrations to occur between patches inhabited by the different populations. We show that if hybridization between different cycle lengths produces offspring that have an intermediate life‐cycle length, then predation acts disproportionately to select against the hybrid offspring. This happens because they emerge in low densities without the safety‐in‐numbers provided by either parent population. Thus, prime‐numbered life cycles that can better avoid hybridization are favored. How…

The Global Soil Mycobiome consortium dataset for boosting fungal diversity research

2021

This version of the article has been accepted for publication, after peer review and is subject to Springer Nature’s AM terms of use, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections. The Version of Record is available online at https://doi.org/10.1007/s13225-021-00493-7. Fungi are highly important biotic components of terrestrial ecosystems, but we still have a very limited understanding about their diversity and distribution. This data article releases a global soil fungal dataset of the Global Soil Mycobiome consortium (GSMc) to boost further research in fungal diversity, biogeography and macroecology. The dataset comprises 722,682 fu…

The Contribution of Microchemical Analyses and Diagnostic Imaging to the Conservation and Identification of the Degraded Surfaces of Hellenistic-Roma…

2020

The Archaeological Museum of Palermo (Sicily) has recently presented the results of the restoration of three wall paintings from the House of the Masks of Solunto archaeological site. These significant paintings, dating back to the first century BCE, are the most significant examples of Pompeian style discovered in Sicily to date. The cycle of frescoes unearthed is the best preserved and most complete example of wall painting dating to the Republican Roman period in Sicily. This house was a luxurious private residence built on two floors and centred around a peristyle. This fresco cycle embellished the walls of a banquet room (oecus) discovered during an archaeological excavation carried ou…

Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti

2021

In this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chroma…

Il palazzo di Phestos a Creta: Scavo e restauro

2014

Nel 1900, la Missione Archeologica Italiana di Creta, guidata da Federico Halbherr, con la collaborazione di alcuni archeologi e studenti di archeologia, fra i quali Luigi Pernier, scoprì i resti del palazzo minoico di Festòs, posto a pochi chilometri da Eraklion, capoluogo dell’isola di Creta. Contemporaneamente alla messa in luce dei resti furono eseguiti i primi interventi di restauro e sistemazione, tra questi la pulitura degli interstizi fra i conci lapidei e la stesura di malta cementizia colorata, in modo da intonarla rispetto ai resti, la sistemazione delle parti superiori dei resti murari e la costruzione dei solai in calcestruzzo di cemento armato, un tempo realizzati con struttur…

Il palazzo del Gran Maestro di Rodi (Grecia): fra restauro, ricostruzione e valorizzazione

2018

All’epoca dell’occupazione italiana, dal 1912, dell’isola di Rodi in Grecia, il palazzo del Gran Maestro nella città di Rodi versava, in generale, in stato di rudere. L’edificio, un tempo luogo forte della città, era stato costruito nell’Antichità, rimaneggiato in epoca bizantina, e rifondato, agli inizi del sec. XIV, dai Cavalieri di San Giovanni o di Rodi, che lo completarono, quale residenza del loro Gran Maestro, già alla fine dello stesso secolo. Il saggio intende indagare questa straordinaria architettura fortificata, ma soprattutto desidera conoscere i vari restauri succedutisi nel corso degli anni, dal 1912 al 1940, quando Rodi e le Isole italiane dell’Egeo diventarono possedimento …

Le superfici murarie a vista: restauri a Palermo e a Rodi (fine se. XIX- prima metà sec. XX)

2018

Il saggio indaga la particolare tecnica di restauro delle superfici murarie lasciate a vista dell’architettura medievale considerando alcuni casi nella città di Palermo e di Rodi in Grecia (fine del sec. XIX - prima metà del sec. XX). In particolare, dopo avere eliminato gli strati di intonaco, anche quelli coevi alla costruzione, l’architettura medievale era sottoposta ad interventi di rifacimento delle superfici sia interne che esterne, mediante la tecnica dell’”impiallicciatura”, cioè ricostruendo i filari dei conci delle murature con materiale simile per natura, dimensioni e colore, o estraendo il concio degradato, resecando la parte ammalorata e ricollocandolo nella muratura. Questa op…

The coast of Altavilla Milicai east of Palermo. Story of a forgotten coastal landscape between illegal building, architectural-landscape emergencies …

2017

La costa di Altavilla Milicia ad est di Palermo. Storia di un paesaggio costiero dimenticato fra edifici illegali, emergenze architettoniche-paesaggistiche e la necessità di protezione. La costa che va da Bagheria a Cefalù è caratterizzata dalla presenza di numerose costruzioni abusive che, in tantissimi casi sorgono sulla stessa battigia in dispregio a qualsiasi norma urbanistica. Questo fenomeno invasivo, in parte anche profdotto da pianoi regolatori urbanistici non curanti dei valori paesaggistici fortemente presenti in questa area, ha avuto inizio dagli anni settanta del Novecento, con la ricerca di seconde case per la residenza stagionale soprattutto da parte degli abitanti di Palermo.…

Biodeterioration of cardboard-based liquid containers collected for fibre reuse.

1999

Liquid packaging board (LPB) collected in Germany is processed in Finland as recycled fibre and as plastic reject for incineration. The chemical, biological and physical changes occurring in recycled LPB bales were monitored during storage of six and 18 months. The moisture content in the core of the bales ranged from 7% to 53%, and pH values varied from 6.0 to 8.5. The average amount of mesophilic bacteria per container was 1.5 x 10(7) - 5 x 10(8), which means that recycled LPB pulp cannot be recommended for sanitary use. The concentration of CO2 inside the bale is an indicator of the activity of aerobic microorganisms and might be suitable for identifying deteriorated bales and removing t…
