Abstract:
A set of 15 accessions of maca, Lepidium meyenii Walp., and 25 accessions of yacon, Smallanthus sonchifolius (Poepp. & Endl.) H. Robins., cultivated under Czech field conditions was studied to determine relationships between morphological variability and isozyme polymorphisms. Morphological characterisation of maca included evaluation of length, weight, shape, skin and flesh colour of hypocotyls. In yacon, we evaluated shape, colour, skin texture and flesh colour of tubers, as well as the number of roots. Preliminary results showed that maca forms low-weight hypocotyls (up to only 17.4 g) under Czech field conditions. For yacon, tuber production ranged between 1.4 kg and 3.8 kg. Of the 17 analysed enzymatic systems, only esterase (EST) showed some degree of polymorphism in both crops. It was possible to divide accessions of L. meyenii into two groups and S. sonchifolius into six groups on the basis of isozyme polymorphisms. However, EST polymorphisms do not correspond very well to the morphological characteristics of the underground organs of the crops studied.

ABSTRACT. Variation of specific morphological traits and ploidy level of five Aegilops L. species in Morocco.The genus Aegilops L. represents an important natural source of useful genes for wheat breeding, with particular emphasis on biotic and abiotic stress resistance. For successful crosses, the primarily step is to select appropriate Aegilops accessions. In this paper, we studied five Moroccan species of an Aegilops collection on the basis of spike structure and chromosome number. Twenty-eight specific morphological characters were used to differentiate the species. Statistical analyses, in particular the DFA, allowed the characterization of the genetic variability of the species; the two first standardized axes explained 96,2% of the total variability and 100% of the entities were classified within their own group. In addition, the dendrogram constructed using morphological data reveals a significant variability within and between species. Cytogenetic study revealed four species, A. geniculata Roth, A. triuncialis L., A. ventricosa Tausch and A.peregrina Maire & Weiller, to be tetraploid. However, A. neglecta Req. ex. Bertol., where only two accessions are represented in the collection, revealed to be hexaploid, and can then be classified as A. neglecta subsp. recta Chennav.Key words.

Le genre Aegilops L. représente une importante source de genes, potentiellement utilisables dans Pamelioration des blés cultivés (Triticum spp.) notamment pour la resistance aux stress biotiques et abiotiques. Le choix des accessions Aegilops á employer, dans un programme d' hybridation interspécifique, necessite une caractérisation taxonomique et une evaluation préalables. L'objectif de ce travail a ete d'étudier des accessions, appartenant á 5 especes marocaines constituant une collection d'Aegilops, sur la base de caracteres morphologiques specifiques de l'épi et du niveau de ploYdie. La caractérisation phénotypique a été basée sur l'étude de 28 caracteres morphologiques qui discriminent entre les especes. Les resultats des analyses statistiques, en particulier de l'AFD, ont permis de caractériser la variabilite génetique de ces especes et ant donne un pourcentage d'appartenance á l'espece de 100%. Aussi, les deux premiers axes standardises expliquent 96,2% de la variabilité totale. Un demlrogramme a éte aussi construit, revelant une variabilite interspecifique. L'étude cytogenétique a révélé une tetraploYdie pour A. geniculata Roth, A. triuncialis L., A. ventricosa Tausch et A. peregrina Maire & Weiller. Quant á A. neglecta Req. ex. Bertol., une hexaploYdie a été mise en evidence pour les deux uniques accessions disponibles dans la collection, permettant de leur attribuer le nom A. neglecta subsp. recta Chennav.Mots clés.

Abstract:
This study evaluates the morphological concept of Crepidotus variabilis and similar taxa based on basidiospore and cheilocystidia characters. A phylogenetic analysis of the ITS region clearly distinguished C. variabilis var. variabilis from the two other distinct taxa of the same lineage, C. variabilis var. trichocystis and C. neotrichocystis. We also recognised one additional morphologically similar and undescribed species that belongs to the C. variabilis lineage. All four taxa can also be recognised morphologically using basidiospore and cheilocystidia characters. Our detailed statistical comparison of these characters improves the knowledge of their variability and specifies more precisely the morphological circumscription of the taxa within this group.

Abstract:
The widespread occurrence and local abundance of corbulid bivalves in Neogene deposits of the northern Dominican Republic provide an opportunity to evaluate physical controls on species distributions and intraspecific variability in this group. First and last appearances of species probably do not record speciation and extinction, but instead represent migrations into and out of the study area, and reflect corbulids' preference for marginal-marine and shallow-marine conditions. Corbula cercadica and C. viminea show patterns of intraspecific morphologic variability over time and space. Corbula cercadica shows continuous morphologic variability along a paleoenvironmental gradient of salinity, depth, and bioclastic fabric, whereas variation in C. viminea is morphologically clinal from west to east in roughly contemporaneous sediments, with variability related to sediment type and bioclastic fabric. Ecophenotypic variation or genetic differences, rather than taphonomic processes, seem to control geographic variability within C. cercadica and C. viminea. Although it is not possible to determine whether intraspecific morphologic variability was under genetic control, its stronger relationship with paleoenvironmental conditions relative to stratigraphic position suggests lack of anagenetic morphological evolution.

Abstract:
Opium poppy (Papaver somniferum L.) is currently an important agricultural commodity, with the product being used in the food industry (seed) as well as in the pharmaceutical industry (morphine and other alkaloids). Intensive production of poppy leads to a specific direction of breeding with the aim to obtain highly productive cultivars of the so-called food industry or industrial type. The paper evaluates 57 genetic resources (mostly cultivars), comparing the groups of values representing the indicators of production-significant morphologic and agricultural characters (capsule size; morphine content in poppy straw; weight of dry, empty capsule) and content of morphine in the poppy straw, in relation to the ideotype of poppy, which in these indicators represents 100% of the value. On average lower values in the above indicators were achieved by cultivars with white-coloured seed, including morphine content; concrete data are specified in three cultivars with morphine content in the poppy straw above 0.40%. In blue-seed to grey-seed cultivars, except for the high-morphine cultivar Buddha (1.85% of morphine), we found only six materials with a minimum morphine content of 0.8% in the poppy straw (maximum of 0.92%). These genetic resources also achieved very good values in the morphological indicator and average value in the economic indicator. The results will be used in the selection and classification of suitable genetic resources of poppy in breeding of industrial forms.

Abstract:
Research on morphological variability in second language (L2) acquisition has focused on the syntactic consequences of variability: that is, whether or not morphological variability entails underlying syntactic deficits. The interrelationship between morphological features in their own right has been largely ignored. This thesis addresses the representation of L2 features by investigating the use of default morphology---the outcome of systematic substitution errors employed by speakers of L2 Spanish. It is hypothesized that underspecified features act as defaults; by assumption, those features that are unmarked are underspecified.<br>Evidence to support this hypothesis comes from two sets of experiments conducted on intermediate- and advanced-proficiency L2 Spanish subjects (L1 English). The first set of experiments addresses verbal morphology, and consists of a spontaneous production experiment on person, number, tense, and finiteness, and a comprehension task on person and number. The second set of experiments addresses gender and number in nominal morphology, and consists of a spontaneous production experiment on determiners, an elicited production experiment on clitics and adjectives, and a picture-selection task on the comprehension of clitics. Across tasks and across verbal and nominal domains, errors involve the systematic substitution of underspecified morphology. The observation that morphological variability extends to comprehension, and is qualitatively similar to the variability found in production, counters the suggestion that variability is strictly a product of mere performance limitations on production. Finally, the systematicity of substitution errors suggests that the natural classes of features such as gender, number, tense, and person are acquirable in an L2, regardless of whether or not these features have been instantiated in the native language.

Abstract:
The morphology of members of the isocrinid genus, Endoxocrinus, found by A.H. Clark, 1908, in the Bahamas was examined to see if current classification schemes are valid. Individuals included in this survey belonged to the current species Endoxocrinus prionodes, Endoxocrinus carolinae, and Endoxocrinus parrae. Additionally, individuals of two depth-related morphotypes of E. parrae were examined. Evidence is presented that suggests that E. carolinae should be included in E. parrae, while the validity of E. prionodes is maintained. No evidence was found to warrant the recognition of the two depth-related morphotypes as distinct. Rather, these forms, as well as traditional E. parrae and E. carolinae, encompassed a high degree of variability along a morphological continuum. The study concludes that a revision of the genus should be considered and that isocrinid species can be much more variable in morphology than was previously recognized.

Abstract:
L’étude de la complexité de l’anatomie du cerveau humain nécessite la caractérisation des paramètres multimodaux et multi-échelle obtenus par des techniques de neuroimagerie récentes. Pour ce travail de thèse nous avons tiré profit d’un logiciel automatique actuel d’analyse surfacique d’images cérébrales afin d’extraire les phénotypes structuraux du cortex cérébral humain, c’est-à-dire l’épaisseur corticale, l’aire de la surface, la profondeur sulcale, la courbure et le contenu en myéline intracorticale. L’objectif principal de ce travail a été de caractériser des variables structurales multimodales sur une large base de données de plus de 450 adultes sains âgés de 18 à 57 ans (base de données BIL&amp;GIN) dans le but de décrire la variabilité interindividuelle de l’organisation structurale du cerveau et notamment la recherche de marqueurs de la maturation cérébrale et de la latéralisation. Nous avons tout d’abord pris l’exemple du gyrus de Heschl, support anatomique du cortex auditif primaire, qui possède une grande variabilité en lien avec l’existence de différents profils de duplication du gyrus couplée à de fortes différences interhémisphériques. Nous avons montré qu’une duplication partielle ou complète du gyrus de Heschl était associée à des modifications locorégionales d’épaisseur corticale, d’aire de la surface et de myéline localisée postérieurement à ce gyrus et dans le planum temporale, ces deux régions étant impliquées dans le traitement du langage. Dans une deuxième étude, nous avons recherché les modifications structurales du cortex associées à la maturation tardive (entre 18 et 30 ans) et à l’atrophie corticale liée au vieillissement. Nous avons montré que l’établissement d’un index de maturation basé sur l’intégration de l’épaisseur corticale et de la myéline intracorticale améliorait la discrimination entre les 2 profils de modifications de la substance grise pendant ces deux périodes de la vie. Finalement, nous avons caractérisé les asymétries corticales en utilisant un recalage surfacique des hémisphères qui s’affranchit des différences de morphologie sulcale et de position entre les deux hémisphères. Nous avons mis en évidence des régions pour lesquelles les asymétries d’épaisseur et de surface étaient concordantes (asymétrie gauche ou droite pour les deux variables anatomiques) et des régions pour lesquelles les asymétries étaient opposées (gauche pour l’une des variables et droite pour l’autre). Environ 20% des régions qui montraient une asymétrie d’épaisseur et d’aire présentaient des corrélations négatives entre ces variables. Il est frappant de constater que les deux régions ayant les asymétries les plus fortes, le planum temporale et le sillon temporal supérieur, ont des corrélations positives entre leurs asymétries d’épaisseur et d’aire. Le planum temporale possède une asymétrie gauche à la fois pour l’épaisseur et l’aire alors que le sillon temporal supérieur a une asymétrie droite pour les deux variables. Cette étude démontre qu’il existe des corrélations entre les asymétries d’épaisseur et d’aire qui sont caractéristiques de l’organisation du cortex. Ces régions sont des sites clé pour lesquels il reste maintenant à étudier la pertinence en tant que marqueurs de la latéralisation cérébrale et leurs corrélats fonctionnels<br>Studying the complexity of the human brain anatomy requires the characterization of multimodal and multiscale features obtained by recent in vivo neuroimaging techniques. In the present thesis, we benefited from up to date automated surface-based brain image analysis software to extract structural phenotypes of the human cerebral cortex, namely the cortical thickness, the surface area, the sulcal depth, the curvature and the intracortical myelin content. The principal aim of this work was to characterize multimodal structural variables on a large database of 450 healthy adults aged from 18 to 57 years (the BIL&amp;GIN database) in order to describe the inter-individual variability of brain structural organization and notably the research of candidate markers for brain maturation and lateralization. We first took the example of the Heschl’s gyrus hosting the primary auditory cortex and having high variability due to the presence of different pattern of gyrus duplication coupled with strong interhemispheric differences. We showed that the partial or complete duplication of the Heschl’s gyrus was associated to loco-regional modifications in terms of cortical thickness, surface area and myelin located posteriorly to this gyrus and in the planum temporale, this two regions being implied in language processing. In a second study, we investigated the cortical structural modifications associated to late maturation (between 18 and 30 years) and cortical atrophy linked to aging. We revealed that the computation of a maturation index based on an integration of cortical thickness and intracortical myelin improved the discrimination of two different patterns of grey matter changes during these different stages of life. Finally, we characterized cortical asymmetries using a specific hemisphere surface matching which removed differences in sulcal morphology and position between both hemispheres. We highlighted regions where thickness and surface area asymmetries were concordant (leftward or rightward asymmetry for both anatomical variables) and regions of opposite asymmetries (leftward for one and rightward for the other). About 20% of regions that showed cortical thickness and surface area asymmetries presented negative correlation between these variables. It is striking that the two regions with the strongest anatomical asymmetries; the planum temporale and the superior temporal sulcus had rather positive asymmetry correlations. The planum temporale presented a leftward asymmetry of both cortical thickness and area while the superior temporal sulcus showed a right asymmetry of the two variables. This study demonstrated that there were correlations between thickness and surface area asymmetries, characteristics of the cortex organization. These areas are key sites for which it now remains to study the anatomical relevance as markers of brain lateralization and its functional correlates

Thesis (M.

Several electrocardiographic (ECG) measures such as heart rate variability, heart rate turbulence, deceleration capacity, T-wave altemans, and morphologic variability have been used to identify patients at an increased risk of recurrent myocardial infarctions and cardiovascular death. In this work, we develop a new ECG-based measure for patient risk stratification called weighted morphologic variability. This measure is based on assessment of beat-to-beat changes in the morphology of consecutive beats. Weighted morphologic variability identifies patients who are at more than four-fold risk for cardiovascular death, which is an improvement in ECG-based risk stratification. The body of this work suggests that prognosticating patients based on electrocardiographic measures is an effective way of identifying those at risk of adverse cardiovascular outcomes.<br>by Joyatee Mudra Sarker.<br>M.Eng.

Abstract:
There is intrinsic surgical variability in the practice of total knee arthroplasty (TKA), and thus computational analyses of TKA should account for this variability to ensure clinical applicability and robustness of results. Statistical inputs within computational analyses have been used to assess the biomechanical characteristics of TKA implants [1], and such methodologies are promising when applied to morphological analysis of TKA in order to motivate component design, assess current designs, and improve the understanding of surgical outcomes. Analyses to date either directly use actual TKA component placement or bone resection data [2], or assume a single set of parameters for placement and resection across the entire specimen group that was investigated [3], and thus do not account for surgical variability. This could be due to a lack of available data to quantify clinical variability in TKA component placement.

Abstract:
Advanced analyses of soft biological tissues have shown substantial subject-specific variability in mechanical properties [1]. Such variability is also easily observed at a geometrical or morphological level, and has been reported also in mechanical tests on biological tissue samples [1, 2]. While there is wide interest in reproducing accurate geometries for subject-specific modeling, constitutive parameters for mechanical models often use averaged data from mechanical tests [3]. Outliers are typically neglected, and only the ‘mean’ tissue behavior is considered. However, due to an increased interest in using multi-scale and finite element (FE) models for medical device testing and surgical planning [4], understanding of the variability of the outlier tests becomes increasingly important. In particular, by using detailed mechanistic constitutive models, it might be possible to classify the different mechanical behaviors observed on the basis of the changes in the constitutive parameters. This process could lead to the definition of a library of different ‘healthy’ or ‘diseased’ constitutive parameters to be used in computational analyses.

Abstract:
Coastal foredunes are topographically high features that can reduce vulnerability to storm-related flooding hazards. While the dominant aeolian, hydrodynamic, and ecological processes leading to dune growth and erosion are fairly well-understood, predictive capabilities of spatial variations in dune evolution on management and engineering timescales (days to years) remain relatively poor. In this work, monthly high-resolution terrestrial lidar scans were used to quantify topographic and vegetation changes over a 2.5 year period along a micro-tidal intermediate beach and dune. Three-dimensional topographic changes to the coastal landscape were used to investigate the relative importance of environmental, ecological, and morphological factors in controlling spatial and temporal variability in foredune growth patterns at two 50 m alongshore stretches of coast. Despite being separated by only 700 m in the alongshore, the two sites evolved differently over the study period. The northern dune retreated landward and lost volume, whereas the southern dune prograded and vertically accreted. The largest differences in dune response between the two sections of dunes occurred during the fall storm season, when each of the systems’ geomorphic and ecological properties modulated dune growth patterns. These findings highlight the complex eco-morphodynamic feedback controlling dune dynamics across a range of spatial scales.
