Tree age‐dependent changes among epiphytic bryophyte communities in Mediterranean environments. A case study from Sicily (Italy)
2010
Abstract The epiphytic bryophytes inhabiting trees of different size/age in a Quercus ilex wood from Madonie Mountains (northern Sicily, Italy) were studied with the purpose of describing the changes that take place in the bryophyte stratum during the tree lifespan. Results indicate an increase of bryophyte cover combined with a progressive decrease of epiphytic lichens and the existence of an active process of species and community substitution. The way these processes take place corresponds to a succession sequence, which is characterised by a high number of pioneer species on the youngest trees and a sharp decline of species number on middle‐aged and old trees due to the great spread of …
Geological Map of the Rocca Busambra-Corleone region (western Sicily, Italy): explanatory notes
2011
The geology of the Rocca Busambra-Corleone region, in centralwestern Sicily, is relevant to the understanding of the central sector of the Maghrebian-Sicilian fold-and-thrust belt. In the investigated area Mesozoic shallow- and deep-water carbo - nate deposits pertaining respectively to the Trapanese and the Sica - nian successions, and a thick Oligo-Miocene numidian flysch body, crop out. Minor outcrops of Cretaceous-Palaeogene Sicilide complex and syn-orogenic deposits of the Late Serravallian-Early Messinian Castellana Sicula and Terravecchia formations are also present. A structural analysis reveals complex tectonic relationships between the Trapanese carbonate platform tectonic unit (t…
<i>Acacia cyclops</i> A. Cunn. ex G. Don (Leguminosae) in Italy: first cases of naturalization
2012
The first two cases of naturalization of <i>Acacia cyclops</i> are reported for Italy. Young trees were observed growing in the wild some 15 years ago on Linosa (Pelagie Islands, Strait of Sicily). A decade later, this alien plant should no longer be considered as a casual, since a very intensive process of self-sown regeneration has been observed in some plantations on Lampedusa, the major island of the same Archipelago. The available literature suggests the need for careful monitoring of the ongoing invasion process, as <i>A. cyclops</i> has already shown a very invasive behaviour elsewhere within Mediterranean-type biomes due to its ability to withstand high envir…
Rotifer vertical distributions in a meromictic basin of Lake Banyoles (Spain)
1993
The vertical distribution of rotifer populations has been analyzed in a meromictic basin (III) of the karstic Lake Banyoles. This basin had, at the time of the study, an anaerobic monimolimnion from around 17 m in summer or 21 in winter to 25 m, its maximum depth. However, below this layer a warmer micro aerophiliczone with suspended marls is found in a chimney to a depth of 130 m.
New Lower Devonian Polygnathids (Conodonta) from the Spanish Central Pyrenees, with comments on the early radiation of the group
2014
The comprehensive study of six Pragian-lower Emsian (Lower Devonian) sections from the Spanish Central Pyrenees has yielded a rich assemblage of conodont faunas, highlighting an important succession of Polygnathus species. Among them, the presence of the biostratigraphical markers P. pireneae , P. kitabicus, P. excavatus excavatus and P. exc. 114 stands out. This conodont succession allows the identification of the Pragian/Emsian boundary and the early Emsian zones and subzones: the kitabicus Zone and the Lower and Middle excavatus subzones. It is also remarkable the presence of three new polygnathid species: P. aragonensis n. sp., P. carlsi n. sp. and P. ramoni n. sp. Additionally, P. pan…
Microbial succession of nitrate-reducing bacteria in the rhizosphere of Poa alpina across a glacier foreland in the Central Alps
2006
International audience; Changes in community structure and activity of the dissimilatory nitrate-reducing community were investigated across a glacier foreland in the Central Alps to gain insight into the successional pattern of this functional group and the driving environmental factors. Bulk soil and rhizosphere soil of Poa alpina was sampled in five replicates in August during the flowering stage and in September after the first snowfalls along a gradient from 25 to 129 years after deglaciation and at a reference site outside the glacier foreland (> 2000 years deglaciated). In a laboratory-based assay, nitrate reductase activity was determined colorimetrically after 24 h of anaerobic inc…
International Student Migration in Finland
2021
There is increasing attention on the retention of international students with many stakeholders desiring to keep international students for long-term economic growth. This study examines the factors affecting international students to stay in Finland five years after initial enrolment with particular focus on the role graduation plays in students staying or leaving. Tracking 11 (years) entering cohorts for five years across national (Finland) data registries, we found evidence of an inverse relationship between graduation, degree type, and the probability of staying; higher the degree level of graduation, the decrease in probability an international student stays. We conclude that while gra…
VERIFICA DELL’ATTECCHIMENTO DEGLI INNESTI-TALEA DI VITE DOPO LA FORZATURA MEDIANTE TECNICHE TERMOGRAFICHE E MECCANICHE
2016
Grafting is an important technique for getting good yields in plant multiplication. Understanding the success of the graft after the incubation room is important to the evaluation of the suitable grafting for the open field (nursery). Successful grafting in vines requires the development of a functional vascular system between the scion and the rootstock. The graft compatibility and its augmentation depend upon various natural factors like environment, weather, soil conditions and protective measures etc. The present study examines the capability of thermography, mechanical and electrical techniques to assess the graft quality and successful of Vitis vinifera after the incubation room. Afte…
A person-oriented approach to sport and school burnout in adolescent student-athletes: The role of individual and parental expectations
2017
Abstract Objectives The present study aimed to examine what kind of burnout profiles exist among student-athletes based on their sport and school burnout symptoms. Moreover, it was investigated whether athletes' expectations of success in sport and school, on the one hand, and parental expectations, on the other hand, were predictors of the likelihood of the athlete to show a certain profile, after taking into account the effects of gender, grade point average, type of sport, and level of competition. Design and methods The participants were 391 student-athletes (51% females) from six different upper secondary sport schools in Finland, and 448 parents (58% mothers). The athletes filled in q…
Exploring the Critical Success Factors in Social and Health Care Information Systems Project Procurement
2020
A welfare reform involving the mixing of social and health services is being introduced by the Finnish government. Several factors have been identified for this shift, the most relevant of which is that many information systems are not interoperable and data-related problems have been identified. Management and isolated offers of service. Digitalizing to solve these issues is part of the government’s policy. This paper outlines the change landscape and explores the architectural options of the proposed digitalisation process and crucial success factors. The Undertaking The design is applied to the largest county, which consists of over 1,900 information systems related to social support and…
