O licuri (Syagrus coronata) é uma palmeira que floresce e frutifica durante o ano inteiro, tendo grande importância ecológica e econômica, uma vez que fornece hábitat e alimento para diversos seres vivos, inclusive para a subsistência de populações humanas. Em populações nativas encontradas no Parque Nacional do Catimbau, a fenologia da espécie foi monitorada em quatro áreas (total de 120 indivíduos). Também foram identificados os visitantes florais, a composição química dos odores florais e a variação de temperatura das flores durante a antese, levando em consideração as fases reprodutivas (feminina e masculina), o sexo das estruturas reprodutivas (flores pistiladas e estaminadas) e o período do dia (manhã e noite). O fitness reprodutivo foi comparativamente analisado para polinização diurna vs noturna, entomófila vs anemófila. Amostras de odores florais foram coletadas através de “headspace” dinâmico a partir de flores pistiladas e estaminadas, bem como nas suas respectivas brácteas. O estudo da fenologia evidenciou duas áreas sazonais, enquanto duas outras produziram eventos contínuos de reprodução. A riqueza e abundância de visitantes florais foram maiores nas inflorescências masculinas que nas femininas. O fitness reprodutivo não mostrou diferença entre os tratamentos de polinização. Por sua vez, análises de odor floral demonstraram diferenças de compostos isolados nas brácteas e inflorescências, mas não entre as fases reprodutivas; a quantidade de odor emitido diferiu nas brácteas nas fases femininas e masculinas, mas não nas inflorescências, as quais apresentaram quantidades similares de compostos. Não foi evidenciado fenômeno de termogênese floral, nem ao longo do dia, nem entre as fases reprodutivas. Estratégias como o fornecimento de recursos em abundância e hábitat para visitantes florais, liberação diferenciada de odor e floração contínua, podem estar associadas à garantia do fluxo gênico dentro e entre populações dessa espécie de Syagrus.
Licuri (Syagrus coronata) is a palm tree that blooms and bears fruit throughout the year, having an ecological and economic importance, as it provides habitat and food for many living beings, including for the livelihoods of human populations. In native populations, found in Catimbau National Park, the phenology of species was monitored in four areas (total 120 individuals). Also flower visitors were identified, the chemical composition of floral scents and temperature variation of flowers at anthesis, taking into account the reproductive stages (male and female), sex of the reproductive structures (pistillate and staminate flowers) and the period the day (morning and evening). The reproductive fitness was comparatively analyzed for day vs. night pollinated and entomophilous vs anemophilus. Samples of floral odours were collected through "headspace" dynamic from pistillate and staminate flowers as well as in their respective bracts. The study of phenology showed two seasonal areas, while two others produced continuous reproductive events. The richness and abundance of floral visitors were higher in male than in female inflorescences. The reproductive fitness showed no difference between pollination treatments. In turn, floral odor analysis showed differences in isolated compounds in the bracts and flowers, but do not between the reproductive stage; the amount of odor emitted differed in the bracts in male and female phases, but not in inflorescences, which showed similar amounts of compounds. Floral thermogenesis phenomenon was not evidenced neither throughout the day nor between reproductive stages. Strategies such as providing abundant resources and habitat for floral visitors, differentiated release of odor and continuous flowering, may be associated with the guarantee of gene flow within and among populations of this species of Syagrus.

Full textd’analyses chimiques de phéromones sexuelles et de parfums floraux, (ii) d’analyses génétiques avec des outils moléculaires, et (ii) de tests de comportement réalisés sur les insectes in situ nous ont permis d’éclairer certains aspects méconnus de ces interactions inter-spécifiques. La pollinisation des orchidées du genre Ophrys est assurée par des mâles d'abeilles ou de guêpes solitaires qui opèrent une tentative d’accouplement (pseudocopulation) sur le labelle des fleurs. L'attraction des pollinisateurs est généralement hautement spécifique, régie par un mimétisme des signaux (chimiques, visuels, tactiles) des femelles des espèces d'insectes concernés. Malgré cette spécificité, des hybrides se forment occasionnellement en conditions naturelles, témoignant de la perméabilité partielle des barrières d'isolement reproductif entre espèces. Au cours de
ce programme de recherche, nous avons entrepris l’étude des interactions Ophryspollinisateurs en mettant l’accent sur trois aspects spécifiques, à savoir (i) la sélection des caractères floraux par les pollinisateurs, (ii) l'isolement reproductif entre espèces d'Ophrys sympatriques, et enfin (iii) l'évolution des caractères floraux au sein d'un complexe d'espèces-soeurs d'Ophrys associées à différents pollinisateurs.

Full textFresh human sweat is odorless. Odoriferous volatile compounds are produced by the metabolism of bacteria living on the skin, generating strong malodor. Sweaty body odors do also appear on clothes during use, and especially on synthetic fabrics. The aim of this document is to improve understanding of odor emission by investigating subject effect, microbiota effect and fabric effect on the emission of odoriferous volatile compounds.Odors of perspiration are hereby globally approached with a wide use of methods and experimental devices, for microbial flora study as well as for odoriferous volatile compounds emission study.First, microflora enumeration has been simultaneously processed on the skin and on the fabric after exercise for 15 subjects. This experiment allowed an evaluation of the average bacterial transfer yield during physical activity and the beginning of the investigation of its effect on odor emission.A molecular biology methodology has then been developed in order to refine these results. Monitoring of qualitative composition of the microbiota has been performed to study the stability of the armpit’s ecosystem on a subject during 3 months. Specific microbial transfer from subject’s skin to clothe has been performed for 4 textile fabrics (including cotton and PET). This leaded to characterize the effect of specific bacterial transfer on odor emission from fabric.The last chapter is dedicated to the study of the emission of odoriferous volatile compounds over time using olfactory measurements and electronic nose for 8 selected fabrics. Principal component analysis targeted 9 chemical compounds that have been selected as malodorous behavior indicators for a given fabric. Those 9 compounds could be used for setting up a fitted physicochemical method of malodor.To conclude, this study helped to understand the effect of 3 factors in odor perception from a fabric after sport : subject, microbial flora and fabric. Perspectives have been charted on contact microbial contamination, but also on odor, and especially on desorption of odoriferous volatile molecules from a textile or knitted matrix. The solutions that could be used to limit malodorous emission from fabrics have also been discussed
