Standardization proposal for the mapping of Caulerpa taxifolia expansion in the Mediterranean sea
1999
Fourteen years after the first observation of Caulerpa taxifolia (Valh) C. Agardh in the northwestern Mediterranean Sea, this green alga of tropical origin is now present in five countries (Spain, France, Monaco, Italy and Croatia). By the end of 1997, more than 46 km(2), at depths of between 0 and 50 m, were found to be affected by this expansion. A standardization of the cartographic procedure is proposed here. Such a standardization is necessary to compare maps produced by various organizations from different countries. For a given independent station, it is based on the definition of three levels of colonization:Level I refers to a station where one or several colonies less than 100 m a…
Gene flow and population admixture as the primary post-invasion processes in common ragweed (Ambrosia artemisiifolia) populations in France
2010
*An improved inference of the evolutionary history of invasive species may be achieved by analyzing the genetic variation and population differentiation of recently established populations and their ancestral (historical) populations. Employing this approach, we investigated the role of gene flow in the post-invasion evolution of common ragweed (Ambrosia artemisiifolia). *Using eight microsatellite loci, we compared genetic diversity and structure among nine pairs of historical and recent populations in France. Historical populations were reconstructed from herbarium specimens dated from the late 19th to early 20th century, whereas recent populations were collected within the last 5 yr. *Re…
Soil health through soil disease suppression: Which strategy from descriptors to indicators?
2007
International audience; Soil is a component of primary importance in crop production, even if it is often neglected, or only regarded as a physical support for the growth of plants. However, with the increasing societal concerns for the sustainability of agriculture, soil must be considered as a living system. Its quality results from the multiple interactions among physicochemical and biological components, notably the microbial communities, primordial for soil function. Crops are threatened by soil-borne diseases. These are often difficult to control, because of the “hidden” status of the pathogens and also because of the absence, noxiousness or lack of efficacy of chemical treatments. In…
Sex-Specific Sociodemographic Correlates of Dietary Patterns in a Large Sample of French Elderly Individuals
2016
International audience; This cross-sectional analysis provides up-to-date information about dietary patterns (DP) and their sociodemographic correlates in European elderly individuals. We studied 6686 enrollees aged 65+ (55% women) in the ongoing French population-based NutriNet-Sante e-cohort. Diet was assessed via three 24 h records. The sex-specific correlates of factor analysis derived DP were identified with multivariable linear regression. Using 22 pre-defined food groups, three DP were extracted. The "healthy" DP (fruit, vegetables, grains, nuts, fish) was positively associated with education, living alone, and being a former smoker (women), and negatively associated with being overw…
Temporal dynamics of the tick Ixodes ricinus in northern Europe : epidemiological implications
2017
Background Tick-borne pathogens pose an increasing threat to human and veterinary health across the northern hemisphere. While the seasonal activity of ticks is largely determined by climatic conditions, host-population dynamics are also likely to affect tick abundance. Consequently, abundance fluctuations of rodents in northern Europe are expected to be translated into tick dynamics, and can hence potentially affect the circulation of tick-borne pathogens. We quantified and explained the temporal dynamics of the tick Ixodes ricinus in the northernmost part of its European geographical range, by estimating (i) abundance in vegetation and (ii) infestation load in the most common rodent speci…
Socialt stöd, känsla av ensamhet och psykiska besvär bland finlandssvenska ungdomar
2021
I den här studien utforskades ifall det förekommer sociodemografiska skillnader i upplevelse av psykiska besvär, socialt stöd och känsla av ensamhet bland finlandssvenska ungdomar. Det undersöktes även ifall ungdomarnas upplevelse av psykiska besvär kan förklaras med familje-, kamrat- och klasskamratstöd samt känsla av ensamhet. Utöver det utforskades ifall samband mellan socialt stöd och psykiska besvär kan förklaras med känsla av ensamhet.
 Som datamaterial användes WHO:s skolelevstudie (WHO-Koululaistutkimus) från 2018 med ett deltagarantal på 599 svenskspråkiga elever från årskurs 5, 7 och 9 (Målder = 11,9/14,0/15,9; svarsprocent 38 %). Som statistiska analysmetoder användes Pearso…
Estudio ex post-facto del estrés a largo plazo en una muestra de personas adoptadas
2016
In this work we study the impact of relinquishment and the adoption process in posttraumatic symptoms in a group of 55 adults that were adopted as children before 1970. The effects of institutionalization, maltreatment, traumatic revelation of the adopted status and stressful life events have also been studied. No significant differences were found between institutionalized and non-institutionalized adoptees in posttraumatic symptomatology. However, adoptees who suffered maltreatment, traumatic revelation and high level of stressful life events scored significantly higher in intrusion and arousal than those adoptees non-maltreated, without traumatic revelation and with low level of stressfu…
Alkoholinkäytön aiheuttama liikennekuoleman riski Suomessa
2023
Tässä tutkimuksessa analysoidaan juopumuksen asteen vaikutusta kuolemaan johtavan liikenneonnettomuuden riskiin moderneilla tilastollisilla menetelmillä. Tutkimuksen pääaineistona ovat vuosina 2005–2014 Suomessa tapahtuneet kuolemaan johtaneet moottoriajoneuvo-onnettomuudet, joissa oli mukana henkilöauto aiheuttajana tai muuna osallisena. Pääaineistoa täydennetään ratsiatutkimuksista julkaistuilla tilastoilla. Keskeisiä käytettyjä mittareita ovat riskisuhde sekä vakioitu riskisuhde, josta on poistettu sekoittavien muuttujien vaikutusta. Tutkimuksen ensimmäisenä tavoitteena on selvittää, miten pieni veren alkoholipitoisuus alkaa lisätä liikenneonnettomuuden riskiä, ja toisena tavoitteena on …
Hyvinvointivaltiokansalaisuusdiskurssit neljän suurimman puolueen eduskuntavaaliohjelmissa 1991–2019
2020
Tutkimuksen tavoitteena on tehdä näkyväksi millaisia ideologisia valintoja Suomen neljä suurinta puoluetta ovat tehneet eduskuntavaaliohjelmissaan suhteessa hyvinvointivaltiokansalaisuusdiskursseihin 1991 vuodesta alkaen. Tarkastelemme erityisesti vaaliohjelmissa tuotettuja kansalaisen poliittisia ja sosiaalisia oikeuksia ja velvollisuuksia sekä kansalaisen ja valtion välistä oikeudellinen sidettä ja sen legitimointia. Tarkastelemme puolueiden hyvinvointivaltiokansalaisuusdiskursseja pohjoismaisesta hyvinvointivaltiomallista käytävän kamppailun viitekehyksessä. Kansalaisuustulkinnat ohjaavat yhteiskuntapolitiikkaa ja esimerkiksi määritelmät kansalaisten tarpeista vaikuttavat palvelurakentee…
Côté mauvaises herbes, tir de barrage sur trois envahissantes
2006
National audience; Les plantes envahissantes sont évoquées à la conférence sur les zones non agricoles de l'AFPPà Avignon les 11 et 12octobre 2006. La situation à leur égard en France et en Europe est présentée, notamment les dispositions réglementaires et l'identité des 34 principales espèces. Deux communications traitent de l'ambroisie à feuille d'armoise Ambrosia artemisiifolia. Un point sur les méthodes de lutte mécanique, chimique, etc.) insiste sur l'intérêt de la prévention (enherbement, etc.)et de la concertation entre acteurs agricoles et non agricoles. Des essais de lutte chimique (glyphosate ou glufosinate-ammonium en 2004 et 2005, les montrent équivalents et intéressants en débu…
