Quantity and Quality of Aquaculture Enrichments Influence Disease Epidemics and Provide Ecological Alternatives to Antibiotics
2021
Environmental heterogeneity is a central component influencing the virulence and epidemiology of infectious diseases. The number and distribution of susceptible hosts determines disease transmission opportunities, shifting the epidemiological threshold between the spread and fadeout of a disease. Similarly, the presence and diversity of other hosts, pathogens and environmental microbes, may inhibit or accelerate an epidemic. This has important applied implications in farming environments, where high numbers of susceptible hosts are maintained in conditions of minimal environmental heterogeneity. We investigated how the quantity and quality of aquaculture enrichments (few vs. many stones
"Naturally wired to learn" : beliefs about SLA in an online community
2013
Tämän tapaustutkimuksen tarkoituksena on kartoittaa tofugu.com – kieli- ja kulttuuriyhteisön uskomuksia kielenoppimisesta. Tutkimuksen tavoitteena on selvittää, mitä oppimisuskomuksia yhteisön keskusteluissa esiintyy, miten ne rakentuvat julkaisijan artikkeleissa sekä yleisön ja julkaisijan välisissä diskursseissa. Tutkin tätä analysoimalla syys- marraskuussa 2011 julkaistua kielenoppimiseen liittyvää artikkelisarjaa kommentteineen. Vastaavaa internetyhteisön oppimisuskomuksia kartoittavaa tutkimusta ei ole aikaisemmin tehty. Tutkielmani teoriatausta ja viitekehys pohjautuu Vygotskin sosiaalisen konstruktivismin oppimiskäsitykseen, jonka mukaan muokkaamme tietoamme sosiaalisissa konteksteis…

Impact of Leptospermone, a Natural β-Triketone Herbicide, on the Fungal Composition and Diversity of Two Arable Soils
2019
International audience; Impact of leptospermone, a β-triketone bioherbicide, was investigated on the fungal community which supports important soil ecological functions such as decomposition of organic matter and nutrients recycling. This study was done in a microcosm experiment using two French soils, Perpignan (P) and Saint-Jean-de-Fos (SJF), differing in their physicochemical properties and history treatment with synthetic β-triketones. Soil microcosms were treated with leptospermone at recommended dose and incubated under controlled conditions for 45 days. Untreated microcosms were used as control. Illumina MiSeq sequencing of the internal transcribed spacer region of the fungal rRNA re…

The Role of Financial and Managerial Variables on the Policy towards Home-grown Players in English Soccer
2012
The training and development of young players both as athletes and individuals is one of the task soccer governing bodies assign to professional soccer team in order to fully exploit the social aspects of sport activities. Recently UEFA imposed new rules to improve the use of home-grown players. We analyze a panel data of English Premier and Championship league clubs for the seasons 2001-02 to 2005-06 in order to understand what clubs characteristics lead to the employment of young players in the team during official matches. Sport commercialization and the employment of star players have been considered harmful to this role. Our findings suggest that, counter-intuitively, economic and comm…
The community of Cystoseira brachycarpa J. Agardh emend. Giaccone (Fucales, Phaeophyceae) in a shallow hydrothermal vent area of the Aeolian Islands …
2014
A Cystoseira brachycarpa community from a vent area off Panarea Island (Italy) was investigated in two sites at different pH values. At low pH, species richness and coverage were low and the community displayed a reduced reproductive capacity. Conversely, at normal pH, dense canopies of fertile C. brachycarpa were found.
Fern-dominated Rock Plant Communities of Tajikistan (Middle Asia)
2015
The results of phytosociological research conducted on the fern vegetation of rock crevices and clefts of the Pamir-Alai Mountains in Tajikistan are presented. During field surveys done in 2010–2013, 78 phytosociological relevés were sampled. Plant species were recorded according to the Braun-Blanquet cover-abundance scale. A synopsis of the fern communities of the montane and high altitude zones in Tajikistan is proposed. In the examined vegetation plots, species of 9 ferns, 58 angiosperms and 13 mosses were recorded. The most frequent ferns were: Cystopteris fragilis, Cheilanthes persica, Asplenium ruta-muraria, Asplenium ceterach, Adiantum capillus-veneris and Cryptogramma stelleri. Six …
Radon levels in the Valencian community (Spain). I. Results in the province of Valencia (1990–1991)
1995
Abstract Two-day radon screening measurements with charcoal canisters were made in buildings in the province of Valencia throughout the years 1990 and 1991. An average indoor concentration of 34 Bq m −3 was found, and 9% of all measurements exceeded the recommended EPA limit of 148 Bq m −3 .
