General introduction -- Molecular markers for comparative and quantitative studies in macropods -- Genetic linkage map construction in the tammar wallaby (M. eugenii) -- Intraspecific variation, sex-biased dispersal and phylogeography of the eastern grey kangaroo (M. giganteus) -- General discussion.
The analysis of DNA using molecular techniques is an important tool for studies of evolutionary relationships, population genetics and genome organisation. The use of molecular markers within marsupials is primarily limited by their availability and success of amplification. Within this study, 77 macropodid type II microsatellite loci and two type I genetic markers were characterised within M. eugenii to evaluate polymorphic levels and cross-species amplification artifacts. Results indicated that 65 microsatellite loci amplified a single locus in M. eugenii with 44 exhibiting high levels of variability. The success of crossspecies amplification of microsatellite loci was inversely proportional to the evolutionary distance between the macropod species. It is revealed that the majority of species within the Macropodidae are capable of using many of the available heterologous microsatellites. When comparing the degree of variability between source-species and M. eugenii, most were significantly higher within source species (P < 0.05). These differences were most likely caused by ascertainment bias in microsatellite selection for both length and purity. -- The production of a marsupial genetic linkage map is perhaps one of the most important objectives in marsupial research. This study used a total of 353 informative meioses and 64 genetic markers to construct a framework genetic linkage map for M. eugenii. Nearly all markers (93.7%) formed a significant linkage (LOD > 3.0) with at least one other marker. More than 70% (828 cM) of the genome had been mapped when compared with chiasmata data. Nine linkage groups were identified, with all but one (LG7; X-linked) allocated to the autosomes. Theses groups ranged in size from 15.7 cM to 176.5 cM, and have an average distance of 16.2 cM between adjacent markers. Of the autosomal linkage groups, LG2 and LG3 were assigned to chromosome 1 and LG4 localised to chromosome 3 based on physical localisation of genes. Significant sex-specific distortions towards reduced female recombination rates were revealed in 22% of comparisons. Positive interference was observed within all the linkage groups analysed. When comparing the X-chromosome data to closely related species it is apparent that it is conserved both in synteny and gene order. -- The investigation of population dynamics of eastern grey kangaroos has been limited to a few ecological studies. The present investigation provides analysis of mtDNA and microsatellite data to infer both historical and contemporary patterns of population structuring and dispersal. The average level of genetic variation across sample locations was exceedingly high (h = 0.95, HE = 0.82), and is one of the highest observed for marsupials. Contrary to ecological studies, both genic and genotypic analyses reveal weak genetic structure of populations where high levels of dispersal may be inferred up to 230 km. The movement of individuals was predominantly male-biased (average N,m = 22.61, average N p = 2.73). However, neither sex showed significant isolation by distance. On a continental scale, there was strong genetic differentiation and phylogeographic distinction between southern (TAS, VIC and NSW) and northern (QLD) Australian populations, indicating a current and / or historical restriction of geneflow. In addition, it is evident that northern populations are historically more recent, and were derived from a small number of southern eastern grey kangaroo founders. Phylogenetic comparisons between M. g. giganteus and M. g. tasmaniensis, indicated that the current taxonomic status of these subspecies should be revised as there was a lack of genetic differentiation between the populations sampled.

Texto completoCon la creciente disponibilidad de datos a escala del genoma para la investigación genética, los genetistas de poblaciones moleculares tienen que trabajar con modelos más complejos, lo que no puede hacerse en un tiempo determinado utilizando el método coalescente estándar. Este escenario llevó al desarrollo de varias aplicaciones alternativas de simulación numérica. A pesar del acceso cada vez mayor a las agrupaciones de computación de alto rendimiento (HPC) en la academia, no se está aprovechando en el campo de la genética de poblaciones. El establecimiento de paralelos entre las aplicaciones existentes es difícil de lograr por los desarrolladores sin una comprensión completa de la HPC, y las nuevas aplicaciones sólo aprovechan las capacidades de multiprocesamiento de una sola computadora. En esta tesis se propone una metodología para establecer un paralelismo entre las aplicaciones coalescentes y utilizar eficazmente toda la potencia de procesamiento disponible de un grupo de HPC. La metodología introduce una estrategia para reducir las comunicaciones intra-nodo en el paradigma de paso de mensajes. Esta solución permite obtener una mejor escalabilidad para las aplicaciones coalescentes que requieren la generación de millones de réplicas. Como resultado, los genetistas de poblaciones pueden utilizar las herramientas coalescentes estándar para ejecutar el análisis de Computación Bayesiana Aproximada (ABC) sin depender de aplicaciones menos precisas. Hemos evaluado nuestra estrategia estableciendo un paralelismo con la aplicación coalescente estándar de facto y ejecutando experimentos a escala del genoma en un conglomerado HPC real. Afinando diferentes aspectos de nuestra metodología, hemos obtenido importantes ganancias de rendimiento, cuadruplicando el speedup de nuestra paralelización inicial, la cual representaba una mejora de 50x sobre la aplicación coalescente de referencia.
With the increasing availability of genome-scale data for genetic research, molecular population geneticists need to work with more complex models, which cannot be done in a time-fashion using the standard coalescent methods. This scenario led to the development of several alternative numerical simulation applications. Despite the ever-increasing access to High Performance Computing (HPC) clusters in the academy, it is not being leveraged in the field of population genetics. Parallelizing existing applications is hard to achieve by developers without a comprehensive understanding of the HPC, and new applications only take advantage of multiprocessing capabilities from a single computer. This thesis proposes a technique to parallelize coalescent applications and effectively use all the available processing power from an HPC cluster. We use a strategy to reduce the intra- node communications in the message-passing paradigm. This solution allows for getting better scalability for coalescent applications that require generating millions of replicas. As a result, population geneticists can use the standard coalescent tools for running Approximate Bayesian Computation (ABC) analysis without relying on less accurate applications. We have evaluated our strategy parallelizing the de facto standard coalescent application and run experiments at genome-scale in a real HPC cluster. We have obtained significant performance gains in tuning different aspects of our approach, leading to a 4x speedup over our initial parallelization, which accounted for a 50x speedup over the reference coalescent application.

Texto completoNatural habitats are more and more destructed and fragmented by urban expansion and human activities. The fragmentation of natural and agricultural areas by buildings and new infrastructures affects the size, connectivity and the quality of habitats. The populations of organisms inhabiting these anthropized territories are then more isolated. However, differentiation between populations of the same organism depends on demographic and genetic processes such as genetic drift, gene flow, mutation and natural selection. Only species that have developed special tolerance mechanisms can persist under changed environmental conditions. The introduction of contaminants such as metals in the environment may influence plants and animals evolution by modifying the evolutionary forces and thus generating differences between populations. In this work, attention was focused on the genetic consequences of metallic pollution on two species, the earthworm Lumbricus terrestris and the plant model Arabidopsis halleri. Two different approaches have been used to study the genetic response to metallic contamination: a population genetic approach was performed in L. terrestris and a quantitative genetic approach was carried on in A. halleri. First, it was a question of identifying and validating new microsatellite markers in L. terrestris. These markers were then used to characterize the neutral genetic diversity in worms collected from agricultural and urban sites. Secondly, genetic architecture of Zn tolerance and Zn hyperaccumulation was conducted investigated for the first time using an intraspecific crossing between metallicolous and non-metallicolous individuals of A. halleri. High density of SNP markers was used to proceed to the QTL mapping step

Texto completoTiivistelmä Luonnonsuojelun perusta on populaatioiden elinkykyyn vaikuttavien tekijöiden tuntemus. Tässä väitöskirjatyössä tutkittiin uhanalaisen orkidean, tummaneidonvaipan (Epipactis atrorubens), elinkykyyn vaikuttavia tekijöitä yhdistämällä pitkäaikaisseurannoilla kerätyt demografiset aineistot geneettisin menetelmin kerättyihin aineistoihin. Lajin populaatioiden geneettisen muuntelun määrän havaittiin olevan pieni ja populaatioiden todettiin olevan geneettisesti erilaistuneita maantieteellisestä skaalasta riippumatta. Geneettisen erilaistumisen syy voi olla alhainen geenivirta, joka on seurausta vähäisestä siemendispersaalista ja huonosta taimettumisesta. Populaatioiden evolutiivista historiaa tutkittaessa havaittiin merkkejä hitaasta jääkauden jälkeisestä kolonisaatiosta, mikä yhdessä alhaisen geenivirran kanssa ennustaa, että lajilla on huono kyky siirtyä sille sopivammille alueille, jos ympäristö muuttuu. Huonoa evolutiivista potentiaalia kuvastava vähäinen geneettinen muuntelu ennustaa, että lajilla on huono kyky sopeutua uusiin ympäristöoloihin. Tämän lisäksi huono taimettuminen laskee elinkykyä etenkin pienissä populaatioissa, mikä näkyy muun muassa pienten populaatioiden matalina kasvukertoimina. Stokastinen vaihtelu vaikutti elinkykyä alentavasti, mikä pitäisikin huomioida nykyistä paremmin elinkykyanalyyseissä. Sekä geneettiset että demografiset analyysit osoittivat taimettumisen mahdollisesti olevan määräävä tekijä tummaneidonvaipan populaatioiden elinkyvylle

Texto completoThe second part addresses linkage-disequilibrium based fine mapping in the French Canadian population. The performance of five linkage-disequilibrium based fine-mapping methods is evaluated using French Canadian chromosomes with one of three diseases found in this population: oculopharyngeal muscular dystrophy (OPMD), hidrotic ectodermal dysplasia (HED), and sensorimotor polyneuropathy with or without agenesis of the corpus callosum (ACCPN). The gene for OPMD was recently mapped and cloned, allowing us to evaluate the performance of the methods with the OPMD results, and to make predictions about the ACCPN and HED putative gene positions. In addition, a new approach to linkage-disequilibrium based fine mapping is presented using FrenchCanadian ascending genealogies. The method involves two steps. First, the likely founding couple of a mutation-bearing chromosome is identified using a computerised randomisation statistic. Then, using a delete-d jackknife resampling scheme, the distribution of gene mapping estimates is calculated from the count of ancestral recombinants and ancestral meioses joining the identified founding couple to the disease gene carriers. Gene mapping estimates are calculated from each marker individually, and confidence intervals of the estimates are derived from the jackknife distributions. The method, when applied to French Canadian families with OPMD, successfully confirmed the localisation of PABP2 responsible for OPMD and performed better than other linkage disequilibrium-based mapping models.

Texto completoENGLISH ABSTRACT: South African abalone, Haliotis midae, has been the subject of major concern regarding its survival and conservation over the last decade or more. Being the only one of five endemic species with commercial value, there is considerable interest and urgency in genetic management and improvement of this species. Limited genetic information and the increasing conservation concern of this species are considered the key motivations for generating information on the micro- and macro-evolutionary processes of H. midae, the overall objective of this study. This study reported the first microsatellite and Single Nucleotide Polymorphism (SNP) markers developed specifically for Haliotis midae. Both these marker types were applied to elucidate the degree of gene flow in nine natural abalone populations whilst testing for two contrasting hypotheses; panmixia versus restricted gene flow. Data was analysed using a series of methodological approaches ranging from traditional summary statistics to more advanced MCMC based Bayesian clustering methods with and without including spatial information. Using only microsatellite data, the historical demography of the species was also examined in terms of effective population size and population size fluctuations. Finally, the evolutionary positioning and origin of Haliotis midae with regards to other Haliotis species was investigated based on mitochondrial and nuclear sequence data. Both microsatellite and SNP data gave evidence for subtle differentiation between West and East coast populations that correlates with a hydrogeographic barrier in the vicinity of Cape Agulhas. Population substructure was supported by AMOVA, FCA and Bayesian clustering analysis. Clustering utilizing spatial information further indicated clinal variation on both sides of the proposed barrier with a region in the middle coinciding with a secondary contact zone, indicating possible historical isolation during glacial periods. Overall, the similar degree of substructure observed with both microsatellites and SNPs supported the existence of contemporary and/or historical factors with genome-wide effect on gene flow. The population expansion measured with the microsatellites was inconsistent with the known recent decline but taking the species’ life cycle and large effective population size into account, a shrinkage in population size will probably only be apparent in a few generations time. On a macro-evolutionary scale, this study presents the first classification of South African abalone as a monophyletic group within the Haliotidae family. The topology based on the combined mitochondrial and nuclear dataset is highly suggestive of a relatively recent radiation of the SA species from the Indo-Pacific basin. The study concludes by describing the most likely factors that could have affected overall population structure and makes suggestions on how the given genetic information should be incorporated into strategies aimed towards the effective management and conservation of Haliotis midae.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse perlemoen, Haliotis midae, is oor die laaste dekade of meer die onderwerp van groot bekommernis betreffende die spesie se oorlewing en bewaring. Aangesien dit die enigste van vyf endemiese SA spesies is met kommersiёle waarde, is daar besonderse belang en erns in die genetiese beheer en verbetering van die spesie. Beperkte genetiese inligting en ‘n toenemende behoefte om die spesie te bewaar is die hoof motivering agter die generering van informasie rakende mikro- en makro-evolusionêre prosesse in Haliotis midae en is die oorhoofse doel van hierdie studie. Hierdie studie beskryf die eerste mikrosatelliete en enkel basispaar polimorfismes wat ontwikkel is spesifiek vir Haliotis midae. Beide tipe merkers is aangewend om die mate van gene vloei in nege wilde perlemoen populasies te ondersoek terwyl twee hipoteses ondersoek is; panmiksie versus beperkte gene vloei. Data is geanaliseer deur gebruik te maak van ‘n reeks metodieke benaderings wat wissel van tradisionele opsommings statistieke tot meer gevorderde MCMC gebasseerde groeperings metodes met of sonder die gebruik van geografiese data. Mikrosatelliet data is ook aangewend om die historiese demografie van die spesie te bepaal in terme van effektiewe populasie grootte asook veranderinge in populasie groottes. Laastens is die evolusionêre posisionering en oorsprong van Haliotis midae teenoor ander Haliotis spesies ondersoek deur gebruik te maak van mitokondriale en nukleêre DNA volgorde data. Beide mikrosatelliet en enkel basispaar polimorfisme data lewer bewys van ‘n subtiele genetiese verskil tussen wes en ooskus populasies wat verband hou met ‘n hidrografiese skeiding in die omgewing van Kaap Agulhas. Populasie struktuur is ondersteun deur die analise van molekulêre variansie (AMOVA), faktoriale komponente analise asook Bayesiese groeperings analise. Groeperings analise wat geografiese informasie insluit dui klinale genetiese variasie aan beide kante van die skeiding aan met ‘n area in die middel wat ooreenstem met ‘n sekondêre kontak gebied. In totaal, ondersteun die soortgelyke mate van struktuur verkry met beide die mikrosatelliete en enkel basispaar polimorfismes die bestaan van hedendaagse en/of historiese faktore met genoom wye invloed op gene vloei. Die toename in populasie grootte vasgestel deur die mikrosatelliet data stem nie ooreen met die onlangse afname waargeneem in die spesie nie, maar met inagneming van Haliotis midae se lewenssiklus en groot effektiewe populasie grootte, sal die afname in populasie grootte moontlik eers oor ‘n paar generasies na vore kom. Op ‘n makro-evolusionêre skaal lewer hierdie studie die eerste klassifikasie van Suid-Afrikaanse perlemoen as ‘n monofiletiese groep binne die Haliotidae familie. Die topologie gebaseer op ‘n gesamentlike mitkondriale en nukleêre datastel is hoogs aanduidend van ‘n relatiewe onlangse verspreiding van die Suid-Afrikaanse spesies uit die Stille-Indiese Oseaan. Die studie sluit af deur die mees algemene faktore te bespreek wat populasie struktuur kon beïnvloed het en maak voorstelle op watter wyse hierdie genetiese inligting aangewend kan word vir die effekiewe beheer en bewaring van Haliotis midae.
