Full textAll their life, individuals have to make decisions that may strongly affect their fitness. To optimize their decisions, they can use personally acquired information but also information obtained from observing other individuals (“social information”). The propensity to gather and use social information and the information meaning might depend on both individual and environmental factors. Studying what drives within- and between-individual differences in social information use should help us understand the evolutionary potential of this supposedly adaptive behaviour. The aim of my PhD was to empirically investigate sources of variability in heterospecific social information use for breeding habitat selection. I worked on a natural population of collared flycatchers (Ficedula albicollis, Gotland Island, Sweden), a passerine species shown to cue on the presence, density, reproductive investment and nest site preference of dominant titmice for settlement decisions. Using both long term and experimental data, I showed that the use of heterospecific social information, measured as the probability to copy tit nest preference, is not heritable but depends on male age and aggressiveness and on tit apparent breeding investment at the time of flycatcher settlement. Using a playback experiment, I also showed that female flycatchers can fine-tune nest site choice according to (i) song features supposedly reflecting great tit (Parus major) quality and (ii) their own aggressiveness level. This thesis highlights the importance of personality in the use of heterospecific social information for breeding site selection in this population, and broadens the traditionally known sources of heterospecific information to fine song characteristics reflecting heterospecifics’ quality. To fully understand the evolutionary mechanisms and consequences of heterospecific social information use, genetically based plasticity and fitness consequences remains to be explored

Full textIn population genetics models, it is commonly assumed that reproduction is a purely stochastic process. This thesis aims at using high density genomic data in order to highlight biological non random phenomena involved in human reproduction. Firstly, we focus on mate choice, and more particularly on a candidate region, the major histocompatibility complex. We confirm previous results showing that this genomic region is involved in mate choice in some human populations. Then, we extend the approach used at the major histocompatibility complex level and apply it to every autosomic gene. Our results suggest that the biological functions potentially influencing mate choice are population specific, or, in other words, are culturally driven. Finally, we focus on transmission distorsion, another process which, along with mate choice, influences the genetic diversity of an individual's descendants. We propose a new approach designed to identify genomic regions whose transmission from one generation to the next does not follow Mendel's laws. Our results show the relationship between transmission distortion and relatedness among spouses at particular genomic loci

Full textThe aim of this PhD is the study of multiples signals in mate choice in the palmate newts Lissotriton helveticus. In a first part, we have made a review about multiples signals theory (article 1). In a second part we have study the effect of ornaments on female mate choice (article 2 et 3). In a third part we have study the trade-off between ornament and male's quality (article 4 et 5). Finally we have investigated the effect of environment heterogeneity on multiples signals and male success (article 5). Globally our result shows that access to reproduction is explain by multiples signals that need to be study in a dynamic framework. Our results have important implication about sexual selection, population dynamic, global change and emergent diseases

Full textIn global changes context, the transformation of rural or natural area into urban area is well studied. At once cause and consequence of global changes, urbanization induces high selections pressures on populations and ecosystems. Factors such as habitat destruction, temperature, luminosity and soil permeability increase diminish biodiversity in town. Environmental characteristics influence phenotypes and survival of organisms. Parents can modulate environmental influence on young or future adult phenotype by investing in reproduction. The aim of this thesis was to understand the role of maternal effects on urban bird phenotypes through description and relation between environmental variation, differences in phenology and in phenotypes within and among populations at different levels of urbanization. For this purpose, two species were selected; the blue tit (Cyanistes caeruleus) and the great tit (Parus major), present along an urbanisation gradient. Monitoring of three reproductive seasons were realised in seven sites in urban area, (parks of Paris), on in three sites in suburban areas and five reproductive seasons in two sites in rural area (Fontainebleau forest and private forest of CEREEP). The phenology, reproductive success and phenotype (coloured signals, body and physiological condition) of adults and nestlings were measured. Thesis results showed that for the two species, phenology did not differ between habitats but reproductive success was lower in Paris than in rural areas. Moreover, great tit coloration and nestling body condition varied with habitat. In order to understand how and which factors influenced great tit colouration, a supplementation experiment was realised after moult. Finally to study temperature influence on great tit reproductive success, a heating nest experiment was realised. Thesis results showed that blue and great tits are highly able to adapt to urban environments even if their reproductive success was decreased in urban area which explained presence in all Europeans cities

Full textSocial information is obtained from the observation of other individuals and their interactions with the environment. It can be intentional (communication and signals) or used inadvertently by bystanders using the presence or the performance of conspecifics. We tested, in Common kestrel (Falco tinnunculus) and European roller (Coracias garrulus), the use of reproductive success and plumage coloration of conspecifics as sources of inadvertent social information in breeding habitat choice. Beforehand, we tested the condition-dependence of coloured ornaments. Correlative results obtained for adults and experimental results obtained for nestlings by manipulating their rearing environment, indicate that plumage coloration is condition-dependent in the two studied species. We manipulated the reproductive success of kestrels on patches of habitat, in order to test experimentally the habitat copying hypothesis. Our results, experimental in kestrels and correlatives in rollers, indicate that individuals take into account the reproductive success of conspecifics in their immigration decisions, as well as density of conspecifics as another source of social information. In addition, plumage coloration also seems to play an important role in breeding habitat choice in these two species. Our results underline the importance of inadvertent social information use in breeding habitat choice. Moreover, our study is the first, to our knowledge, to show that an intentional signal can be diverted in order to be used as a source of inadvertent social information in a different context than that in which it was produced. .

Full textOne of the main challenges for endangered species protection in Africa is to find a sustainable way of integrating objectives of nature conservation with the economic development needs of the local human population. Last West African giraffe population, Giraffa camelopardalis peralta, lives in Niger. These giraffe are unique for several reasons: (i) they represent the only population of peralta sub-species, and (ii) they live in an area densely populated by humans, (iii) which is unprotected and (iv) without predators. In 1996, this giraffe population was almost extinct, with only 50 individuals remaining. Despite signs of population recovery, the sub-species has been classified as “endangered” according to the IUCN Red List assessment criteria. What are the limiting factors for the maximum annual growth rate that has been recorded over the last years in the population? Are favorable conjunctures to this population increasing sustainable? Assessing population conservation requires knowledge of demographic parameters and understanding of the environmental factors driving its spatial distribution. Census data from 1996 to 2009 were analyzed and then demographic parameters through a capture-markrecapture method were determined. A multi-scale spatial analysis allowed me to determine giraffe distribution at both population and herd level (through observations), and to measure habitat selection at the individual level (through GPS satellite collars). Census results, almost exhaustive from 2005 to 2008 highlited an annual growth rate of 12%. This is the maximum growth rate for a giraffe population, and fits with the theoretical maximum growth rate for the species. At the population and herd level, giraffe distribution patterns are driven by food availability. These food resources are seasonally distributed and impacted by human activities. Habitat selection shows that during dry season, giraffe avoid village proximity, where disturbance is high. However, at night giraffe move closer to villages where food resource quantity and quality are higher (tree density, granaries). The use of bean field crop suggests that some cultivated crops gain in attraction and even become favourable to giraffe. This might explain the increase of human-giraffe conflicts. My results clearly show the importance of taking human activities and perception into account, when assessing wildlife conservation strategies
