Full textThe sensory information, mainly olfactory, collected by the insect antenna is coded by several thousands of neuroreceptors which project in the antennal lobe, a well-defined area of the brain. In this center, it is sorted and condensed on a few hundred cerebral neurons at the level of synaptic complexes, called glomeruli. This work demonstrates that these discrete, spheroidal knots of dense neuropile are morphologically, morphometrically and ontogenetically identifiable units. The number of glomeruli per lobe is constant in adults of the cockroach Blaberus craniifer (106 ± 1) and the moth Mamestra brassicae (67 ± 1). A morphological analysis shows that the array of glomeruli is orderly in both species. This allows determining the homologous glomeruli from their relative positions by comparing lobes of the same or different animals. Some glomeruli can even be directly identified from their own anatomical characteristics. A morphometrical analysis, performed according to original techniques, shows that homologous glomeruli have the same dimensions and spatial positions. This allows to precisely map the lobes and to identify the glomeruli by an automated algorithm. However, in the butterfly Pieris brassicae, the antennal lobes are less developed and the glomerular organization is less precise. In Blaberus and Mamestra, species in which males are attracted to females by a sex pheromone, respectively 1 and 2 glomeruli occur which are much more voluminous in the male than in the female. In Pieris, a species in which the attraction is based on visual stimuli, no such macroglomerulus can be observed. Other less conspicuous sexual variations are described. During the postembryonic development of Blaberus, the antennal lobe neurons (about 350) and glomeruli are approximately constant in number. Conversely, the number of antennal neuroreceptors increases strongly: it leads to an exponential growth in glomeruli size. Each glomerulus grows at its own rate. Consequently, the glomerular organization, established as early at the first nymphal stage and invariant at each stage, is slightly modified during development. The sexual glomerulus, which grows at a very high rate, becomes dimorphic only at the time of the imaginal moult. The most quick and slow growing glomeruli are located in 3 different areas. This suggests that the glomerular projections of neuroreceptors of the same type (maybe of the same modality) are specific and organized according to a principle of spatial proximity

Full textDispersal, defined as an individual movement can induce gene flow, is a key process for metapopulations persistence. The addition of new genes in a population can counteract the negative effects of the genetic drift and thus reduce the risk of inbreeding, increasing the extinction rate of populations. The main objective of this thesis was to improve our understanding about the factors inducing dispersal and about the metapopulations functioning. At first, the relationship between this behavior - may be different from one sex to the other (sex-biased dispersal) - and life history traits have been identified in amphibians and butterflies. These relationships were then used to predict dispersal abilities among species for which data about dispersal are still missing. Some life history traits also showed coevolutions with sex-biased dispersal. Adding to these internal factors, the influence of habitat quality, population density and sex ratio were also studied on the dispersal of the cabbage butterfly (Pieris brassicae) in experimental condition (the Metatron). All results of this study highlight the complexity of pressures - internal, environmental or populationnal - acting on the dispersal of individuals (different impact by gender), and improve our understanding about the metapopulations functioning

Full textEtt huvudsyfte för ekologisk forskning är att förstå naturens komplexitet för att kunna förutse effekter av störningar i miljön. I min avhandling har jag fokuserat på ekologiska interaktioner mellan växter och insekter, två av de äldsta terrestra organismgrupperna på jorden. I mina studier har jag undersökt interaktioner mellan den korsblommiga växten svartsenap (Brassica nigra L.) och den specifika herbivoren kålfjäril (Pieris brassicae L.). Båda är väl karaktäriserade modellarter i kemisk-ekologisk forskning. De metaboliska förändringar som sker när växten utsätts för biotisk och abiotisk stress har analyserats hjälp av metabolomik, det vill säga analyser av metabolomet i sin helhet med hjälp av tekniker som vätske- och gaskromatografi kopplad till masspektrometri (LC- och GC-MS), och så kallad headspace-uppsamling av flyktiga organiska föreningar (VOCs). Jag har särskilt undersökt de metaboliska förändringar som sker när växten betas av kålfjärilslarver vid samtidig exponering för: abiotisk stress i form av ozon (O3), en oxidativ luftförorening; ytterligare betning i form av stickande och sugande bladlus (Brevicoryne brassicae); tillsats av oxylipinfytohormon metyl-jasmonat (MeJA), ett ämne som inducerar växtens försvar. Resultaten visar att de metaboliska förändringar som sker i växten vid herbivori med konsekvenser för dess försvar och tillväxt är nära kopplade till de metaboliska förändringar som sker vid stress, vilket visar att växten kan fortlöpande och aktivt omprogrammera sina metaboliska nätverk för att anpassa sig till förändringar i miljön. Avhandlingen visar att genom att utvärdera växtmetabolomet i sin helhet, snarare än att studera enskilda metaboliter, vi kan få bättre förståelse för hur växter reagerar på olika former av stress och därmed också bidra till att vi kan göra förutsägelser för hur förändringar i miljön kan påverka växters fysiologi och ekologi.
