Stranding patterns of the striped dolphin (Stenella coeruleoalba, Meyen 1833, Delphinidae) along the Sicilian coast (Mediterranean Sea)
2019
Along the coasts of Sicily, 73 striped dolphins strandings were recorded from 2013 to 2016. The specimens were collected at the Centro di Monitoraggio e Controllo per Tartarughe marine e Cetacei [Monitoring and Control Centre for Marine Turtles and Cetaceans] at the Istituto Zooprofilattico Sperimentale della Sicilia. Subsequent necropsies were performed to determine the cause of death. The date and stranding location were recorded for each specimen. Total body length, weight, sex, and other key biometric measurements were also recorded for fresh and moderately decomposed specimens. The individuals were divided into three life stage categories on the basis of total body length: (1) newborns…
il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi
2014
riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …
Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean
2022
The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…
Living Coccolithophores from the Gulf of Sirte (Southern Mediterranean Sea) during the summer of 2008
2012
The Gulf of Sirte is a largely unexplored area in the southernmost Mediterranean Sea.We are presenting here 2008 summer data on the distribution pattern of living coccolithophores, a main phytoplankton calcifying group, in 105 samples from 20 stations. The survey includes coastal and offshore stations, enabling us to provide indications on the dynamics of phytoplankton productivity in relation to oceanographic processes. The total coccosphere concentrations show higher values in the offshore stations and lower ones for coastal sites. Umbellosphaera tenuis, Emiliania huxleyi, Florisphaera profunda, Syracosphaera pulchra HOL (Calyptrosphaera oblonga) and Rhabdosphaera spp. dominate the assemb…
Mourning Missing Migrants: Ambiguous Loss and the Grief of Strangers
2019
While the term missing refers to various instances and practices, we focus on the bodies of deceased migrants that remain unidentified, and on the inability of families to mourn someone when there is no body to grieve for. We deploy some ethnographic fragments of how Italian communities sometimes mourn those who are buried without a name and we describe the many problems of mourning someone whose fate is unknown through a discussion of the notion of ‘ambiguous loss’. Our contribution articulates some of the politics around deaths in migration by considering how missing migrants and their bodies are mourned in multiplicity. peerReviewed
Effects of arbuscular mycorrhizal symbiosis on nitrogen dynamics in Mediterranean agro-ecosystems
2010
Le simbiosi arbuscolo micorriziche (AM) sono formate dai funghi appartenenti al phylum Glomeromicota e piante superiori. Le simbiosi (AM) sono caratterizzate dalla penetrazione attiva del fungo dentro negli spazi intercellulari della cortaccia radicale e dalla formazione di strutture di scambio (chiamate ‘arbuscoli’) all’interno della parere cellulare. Gli arbuscoli sono strutture ramificate formate dal fungo AM all’interno della cellula vegetale invasa e sono indubbiamente gli organi chiave della simbiosi. Durante la loro formazione, la cellula vegetale si trasforma radicalmente. In particolare, la membrana cellulare si invagina e una membrana periarbuscolare con una ampia superficie di sc…
Priorities and gaps in Mediterranean bat research evidence: a systematic review for the early twenty-first century
2022
Bat conservation is one of the top global concerns for research today; however, conservation efforts may still be limited and impotent due to inadequacy and scarcity of data. Hence, identifying research trends, threatening factors, species status, and geographical priorities is an essential tool for future conservation, protection and prioritization. Here we conduct a comprehensive systematic review to identify current research priorities, trends, general patterns and gaps regarding Mediterranean bat researches. A total of 97 studies were found in the years spanning between 2000 and 2021. There were 18 studies with sufficient data for qualitative statistical analysis to investigate the impa…
Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily
2014
henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimond…
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…
Presencia y análisis genético de una tortuga bastarda (Lepidochelys kempii) en el mar Mediterráneo
2003
We report on a juvenile Kemp´s ridley sea turtle, Lepidochelys kempii, captured alive by fishermen in the waters off Alicante (western Mediterranean, Spain) on October 15th 2001. The analysis of a 460 base pair fragment of the mt DNA control region revealed a perfect match with haplotype D previously described in this species. This is the second report of L. kempii in the Mediterranean basin.
