Ecologie évolutive de la malaria aviaire : effets des caractéristiques de l'hôte et de l'environnement

2012

Host-parasite interactions are one of the main topics in evolutionary sciences. This complex coevolution depends on several trade-offs and can be influenced by environmental factors. Here, we propose to study host-parasite interactions with a multi-level approach, using experimental and natural population studies, focusing on avian malaria parasites. First, we studied the effect of host characteristics, and more precisely the immune system. The immune system confers benefits in terms of protection against the parasite, but can also generated immunopathological costs. Life history traits, like age or social status, appear to modify parasitemia but not prevalence. In a second part, we evaluat…

Learning to Eat Vegetables in Early Life: The Role of Timing, Age and Individual Eating Traits

2014

Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to repeated exposure, data from the same experiment conducted in three groups of children from three countries (n = 332) aged 4-38 m (18.9 +/- 9.9 m) were combined and modelled. During the intervention period each child was given between 5 and 10 exposures to a novel vegetable (artichoke puree) in one of three versions (basic, sweet or added e…

Personnalité, stratégies d'approvisionnement et d'appariement chez les Diamants Mandarins (taeniopygia guttata)

2011

In evolutionary biology, phenotypic variation has for a long time been considered as the raw material on which natural selection acts. However, research on the consistency of behaviour led to the development of the animal personality concept during the 1990s. This concept was based on the characterization of traits such as neophobia, aggressiveness, exploratory tendencies and risk-taking behaviour. Since then, several studies have shown that personality can evolve through natural selection and is related to many life-history traits, such as dispersal or anti-predator behaviour.Pairing strategies and foraging strategies are two fundamental components of an organism’s life, but their relation…

Tunisian start up support systems : what challenges facing young graduates entrepreneurs? : Sfax case study

2015

In this dissertation we identify the determinants of the longevity and the probability of survival of small businesses created by young graduates benefiting from bank loans at enhanced rates. The focus is on the policy impact of public support for the creation of companies. The data are based on a survey conducted in 2013 under the tutelage of the University of Sfax (Tunisia) of a cohort of 160 companies five years after they were first formed. The response rate was 81.25%. After discussing the issue of the survival of newly-established companies and the factors that promote their survival, we use duration models specifically the Cox model (1972). This analysis allows us to shed light on a …

Le Moyen Age vu d'ailleurs

2009

Entre 2002 et 2006, le programme Le Moyen Âge vu d'ailleurs a réuni des médiévistes européens et latino-américains , au cours de quatre rencontres qui se sont déroulées à Auxerre (2002), São Paulo (2003), Madrid (2005) et Buenos Aires (2006) . Dans un contexte de relative méconnaissance en Europe de ce qui se faisait dans la médiévistique latino-américaine, il s'agissait alors de stimuler les échanges entre de jeunes chercheurs et de chercheurs confirmés autour de l'actualité d'une recherche multiple en train de se construire. Dans ce deuxième volume Hors série du Bulletin du Centre d'études médiévales d'Auxerre, sont regroupées la plupart des contributions présentées au cours de ces quatre…
