The article discusses source materials for history o f Polish-Lithuanian Commonwealth Dietines, found in archival legacy o f Ludwig Gruno, Prince o f Hesse-Homburg. The documents are part o f field chancellery o f the prince, currently preserved in the Military-Historical Museum of Engineer and Signal Corps in St. Petersburg among over a thousand of letters, documents and files illustrating his achievements as commander o f Russian armies in the Caucasus and Poland in 1732-1736. The documents pertain mostly to tsarist army exacting war tribute in form o f food and feed in South- Eastern voivodeships from autumn 1734 to 1736. It was a significant burden to noblemen in Ukrainę, Podolia, Volhy…
Déterminants de la viabilité financière des PME
2020
To be interested in the survival of SME (small and medium-sized enterprises) is to question their ability to create rent and therefore their financial viability. Our panel study on French SMEs, between 2000 and 2018, shows that several factors play a different role in the annuity creation process. If the effectiveness of state governance seems to play a negative role, through the policies put in place, it turns out that debt plays a positive role in the wealth creation process of SME. Given the nature of the goods or service activities, the impact of suppliers and customers is different. In any case, SME in France suffer from a problem of generation renewal and transmission of knowledge whi…
Extrapolation des inventaires de biodiversité incomplets : comment estimer au mieux le nombre d’espèces manquantes et prévoir l’effort additionnel d’…
2016
While approaching or even reaching total completeness remains the idealgoal of any species inventory, incomplete samplings are deemed to become more often the rule, that are significantly more difficult to cope with (such as (micro-) invertebrates, for example).However, once post-operated appropriately, incomplete samplings may provide farmore data than it would seem and it is indeed possible to obtain valuable extra information froma reliable mode of extrapolation of the so-called Species Accumulation Curve.In fact, numerous tools designed for the exploitation of incomplete samplings havealready been proposed in the literature but the concern, with these numerous different tools, isprecise…

Gestion territoriale des adventices : effets des propriétés du paysage sur les communautés adventices et sur leur régulation par les carabidae
2015
Landscape-scale management is known to affect pest and biodiversity levels in agroecosystems. Here, we focus on the lanscape drivers of arable weeds, first by reviewing evidence of direct landscape effects on weed species richness and abundance and then by analyzing current knowledge on landscape effects on carabids, which are well-known weed seed predators that contribute to the biological regulation of weeds. Our analysis shows that (i) heterogeneous landscapes usually harbor higher species richness and more diversified communities than simple ones, (ii) total weed and carabid abundances appear seldomly affected by the landscape context of arable fields and (iii) weed seed predation in fi…
Le syndrome des basses richesses de la betterave sucrière en Bourgogne, un modèle de maladies infectieuses émergentes - Bilan des recherches 1997-2007
2008
National audience; Une maladie inconnue de la betterave sucrière est apparue en Côte d'Or au début des années 1990 et a gagné le reste du bassin sucrier du Centre-est (Bourgogne et Jura). Les programmes d'étude financés par la filière betterave-sucre et Conseil régional de Bourgogne de 1997 à 2007, ont permis d'en élucider entièrement l'étiologie et la transmission, de développer des méthodes de diagnostic moléculaire, et de parvenir à une compréhension globale de son épidémiologie. Les méthodes de lutte directes et agronomiques préconisées ont montré leur efficacité pour limiter les pertes de rendement en sucre associées à cette maladie. Par ailleurs, la biologie de bactéries pathogènes ha…

The syndrome "basses richesses" of sugar beet in France is associated with different pathogen types and insect vectors
2007
International audience; The syndrome “basses richesses” (SBR) of sugar beet in France is associated with two phloem-restricted uncultivable bacteria: a stolbur phytoplasma and a y-3 proteobacteria. The known vector of proteobacteria is a cixiid planthopper, Pentastiridius leporinus (Hemiptera Cixiidae), formerly shown to transmit both the prokaryotes. The role of P. leporinus and of two other planthopper species, Cixius wagneri and Hyalesthes obsoletus, in spreading the two pathogens to sugar beet were compared and quantified. Because of its abundance and high infection rates with proteobacterium, P. leporinus was confirmed to be the economic vector of SBR disease. P. leporinus and C. wagne…
