Catastrophic effects of sand mining on macroinvertebrates in a large shallow lake with implications for management

2019

Sand mining is a human activity that is increasing in inland waters and has profound effects on entire aquatic ecosystems. However, current knowledge of the effects of sand mining on freshwater lake ecosystems remains limited, especially for biotic communities. Here, we investigated the responses of macroinvertebrates to indiscriminate sand mining in a large shallow lake of China. Our results indicated that sand mining significantly increased the content of suspended particulate matter, total nitrogen, total phosphorus and chlorophyll a in the water column both in the sand mining area and the area adjacent to the dredging activities. While there was significantly lower total nitrogen and th…

A comparative analysis between Finns and Chinese : how communication traits affect self-disclosure in intercultural friendships?

2016

Self-disclosure, or the process revealing personal information about oneself to another, plays a vital role in friendship formation and maintenance, and cultured self-disclosure has been proven to be a powerful factor influencing intercultural friendships. Substantial cross-cultural research has shown self-disclosure differs among different cultural groups, but little research has examined what factors facilitate or impede self-disclosure in intercultural friendships. This research answers this call from a communication traits perspective. The focus of this research is to compare similarities and differences between Finns and Chinese in dimensions of self-disclosure in intercultural friends…

Tributo al professor Miguel F. Refojo, PhD, DSc (1928---2016)

2016

[Excerpt] July 21, 2016, Professor Miguel F. Refojo passed away at the age of 88 in Needham (Massachusetts). Saying that Miguel was one of the most renowned Spanish scientists of the second half of the XXth Century does not resembles its actual scientific size. Indeed, Miguel (or “Migüel” as most of his American friends pronounced his name) was a World Class scientist and inventor that will be forever linked to the advances in polymer science applied to the ophthalmic environment. His contributions in the biomedical field start “officially” in 1967 according to the National Library of Medline database (Pubmed-Medline). [...]

Genome-wide detection of signatures of selection in three Valdostana cattle populations

2020

International audience; The Valdostana is a local dual purpose cattle breed developed in Italy. Three populations are recognized within this breed, based on coat colour, production level, morphology and temperament: Valdostana Red Pied (VPR), Valdostana Black Pied (VPN) and Valdostana Chestnut (VCA). Here, we investigated putative genomic regions under selection among these three populations using the Bovine 50K SNP array by combining three different statistical methods based either on allele frequencies (F-ST) or extended haplotype homozygosity (iHS and Rsb). In total, 8, 5 and 8 chromosomes harbouring 13, 13 and 16 genomic regions potentially under selection were identified by at least tw…

Genomic structural diversity in local goats: Analysis of copy-number variations

2020

Copy-number variations (CNVs) are one of the widely dispersed forms of structural variations in mammalian genomes, and are present as deletions, insertions, or duplications. Only few studies have been conducted in goats on CNVs derived from SNP array data, and many local breeds still remain uncharacterized, e.g., the Sicilian goat dairy breeds. In this study, CNV detection was performed, starting from the genotypic data of 120 individuals, belonging to four local breeds (Argentata dell&rsquo

Genetic Improvement of Sweet Chestnut in Sicily (Castanea sativa Mill.) by the Selection of Superior Autochthonous Genotypes

2010

In Sicily, the chestnut (Castanea sativa Mill.) grows in limited areas of the South eastern Mt. Etna volcano and of the Northern Mountains, namely Madonie and Nebrodi. In the Island, chestnut can be considered as a neglected species, because of the modest importance recognized to it for horticultural and forestry exploitation. Recently, the Sicilian regional government founded the 'Horticultural Forestry' project to promote the cultivation of chestnut as possible fruit tree for local city farmer markets, where typical products are usually sold. The project was developed in five steps, carried out during three years by the Dipartimento di Colture Arboree of Palermo University: identification…

Trait impulsivity associated with altered resting-state functional connectivity within the somatomotor network

2020

Knowledge of brain mechanisms underlying self-regulation can provide valuable insights into how people regulate their thoughts, behaviors, and emotional states, and what happens when such regulation fails. Self-regulation is supported by coordinated interactions of brain systems. Hence, behavioral dysregulation, and its expression as impulsivity, can be usefully characterized using functional connectivity methodologies applied to resting brain networks. The current study tested whether individual differences in trait impulsivity are reflected in the functional architecture within and between resting-state brain networks. Thirty healthy individuals completed a self-report measure of trait im…

Data from: Functional structure of European forest beetle communities is enhanced by rare species

2022

From article abstract: https://doi.org/10.1016/j.biocon.2022.109491 ABSTRACT Biodiverse communities have been shown to sustain high levels of multifunctionality and thus a loss of species likely negatively impacts ecosystem functions. For most taxa, however, the roles of individual species are poorly known. Rare species, often the most likely to go extinct, may have unique traits leading to unique functional roles. Alternatively, rare species may be functionally redundant, such that their loss would not disrupt ecosystem functions. We quantified the functional role of rare species by using capture records of wood-living (saproxylic) beetle species, combined with recent databases of their mo…

Dati sulla circolazione della ceramica e sulle rotte del medioevo occidentale attraverso i contesti tardoantichi e medievali di Marettimo

2012

In this paper will be described the ceramic found in the site Contrada Case Romane in the island of Marettimo. On this site a monastic community was founded in the end of the 5th century. This settlement was destroyed in the 8th century and a new one founded in the same location under Norman rule (end of 11th century). The items discovered prove that between the 5th and the 7th century the island was part of a Mediterranean route linking Africa with Rome and the main locations of the western Mediterranean sea. The findings of amphorae produced in the central-southern Tyrrhenian sea between the end of the 7th century and the beginning of the 8th century reveal the close relationship of this …
