Abstract:

Magister Scientiae - MSc<br>Male infertility in humans has increased in the last few decades and could be as high as 40%, while up to 50% of these men have ''unexplained'' (idiopathic) infertility. Although newly developed molecular techniques have great value in detecting subtle causes of male infertility, more detailed sperm functional tests are required to identify compromised fertility, especially in a clinical set-up. Since ethical constraints often preclude the pursuit of many basic research questions in humans, non-human primates (NHPs) have been identified as key models in human-relate

Abstract:

Optimum nutritional levels for most commercial hardwoods of eastern Canada are unknown. This thesis dealt with the development of a method to determine nutritional standards using within site variation in tree growth and foliar chemistry. To this end, sugar maple (n = 87) and red maple (n = 39) trees were sampled in summer 2001 at the Station de biologie des Laurentides. Leaves were sampled for nutrients (N, P, K, Ca, Mg and Mn) and tree stems were measured for determination of basal area growth (BAG). Similar measurements for trees sampled annually during 1995--2001 were also used to m

Abstract:

Determining the genetic basis of reproductive isolation is a fundamental goal in evolutionary biology. Intrinsic reproductive isolation often arises due to epistasis between divergent interacting genes. The rapid evolution of hybrid male sterility is known to have several causes, including the exposure of recessive X-linked incompatibilities in males and the rapid evolution of male reproductive traits. Despite these insights, little is known about the genetics of reproductive isolation during the early stages of speciation. This deficiency inspired parallel studies on the molecular evoluti

Abstract:

Sexual selection is rampant in Nature, and has produced some of the most beautiful and bizarre traits on Earth. Because females are often promiscuous, sexual selection can continue even after mating, as the sperm of multiple males race to fertilize a limited number of eggs. Though post-copulatory sexual selection is ubiquitous and drives both rapid adaptation and divergence between lineages, we know little about the genetic basis of phenotypes subject to this force. To illuminate one of the important mechanisms by which evolution produces a remarkable diversity of traits, we must identify the

Abstract:

This is a broad, quantitative comparison of 12 maple species, representing both canopy and subcanopy growth forms, grown under two ecologically relevant light environments. The maple seedlings responded mainly to light intensity; light quality plays only a minor role in the induction of shade characteristics. While a light-mediated trade off between light and dark reactions of photosynthesis was evident at the chloroplast level, this did not lead to similar differences in assimilaton rates. Gap-grown seedlings showed no apparent compromise in photosynthetic response to dim light and lightfleck

Abstract In sympatric Drosophila species, songs produced by male wing vibration during courtship are an effective mechanism preventing interspecific matings and maintaining sexual isolation between different species. These songs can vary greatly even between closely related species.

Using two cyprinid species, the zebrafish (D. rerio) and the goldfish (C. auratus), I address the hypothesis that the teleost nonapeptides vasotocin and isotocin stimulate male cyprinid reproductive physiology by affecting central neuronal and/or periphe

Problems developing tall oak seedlings of high abundance have become a concern throughout many eastern hardwood forests. The decline in oak seedling recruitment into canopy positions is often attributed to the increasing abundance of shade tolerant midstory species, especially red maple (Acer rubrum L.). Studies have shown that increasing light to the understory by way of a midstory removal has the ability to favor oak seedlings over competitors. The majority of studies to date have examined northern red (Quercus rubra L.) and cherrybark oak (Quercus pagoda Raf.) on productive sites, but relat

Rivulus marmoratus (Cyprinodont; Aplochelidae) is the only vertebrate known to reproduce by obligate internal self-fertilization. Selfing is the ultimate form of inbreeding and leads to virtual homozygosity in approximately ten generations, so that this mode of reproduction is effectively clonal. Populations of this species consist of arrays of homozygous clones, with high clonal diversity and low representation of each clone. Males occur at low frequency (<1%) in most populations, with a few notable exceptions. Females have never been recorded.High frequencies of males have been reported

Abstract:

<p>Detta arbete har undersökt skillnaderna mellan den nuvarande skogsvårdslagen och den föregående. Undersökningen har bestått av två delar, där ena delen är en litteraturstudie av lagarna och den andra är en fältstudie av metoder för att mäta naturhänsynsförändring. Som komplement till fältstudien har en litteraturstudie av undersökningsparametranas naturvårdsnytta. Litteraturstudien av lagarna gick till på följande sätt, inledningen av båda lagarna och hänsynsparagraferna har lästs och jämförts. Fältstudie har gjorts efter metoder som har arbetats fram och sedan testats i fält. De undersökni

Abstract:

Escherichia coli est la bactérie aéro-anaérobie facultative majoritaire du tube digestif de l'Homme et, également, l'espèce la plus fréquemment isolée au cours de bactériémies dans les pays industrialisés. La population de E. coli présente une diversité importante mais néanmoins structurée, avec certains groupes phylogénétiques préférentiellement associés à un mode de vie (e.g. A/B1 et commensal, B2/D et pathogène extraintestinal). De nombreux facteurs de virulence ont été décrits chez les souches pathogènes extraintestinales (ExPEC), mais le pronostic des bactériémies à E. coli semble dépendr

Abstract:

This study, investigating 263 women undergoing trans-vaginal oocyte retrieval for in vitro fertilisation (IVF) found that microorganisms colonising follicular fluid contributed to adverse IVF (pre-implantation) and pregnancy (post-implantation) outcomes including poor quality embryos, failed pregnancy and early pregnancy loss (< 37 weeks gestation). Some microorganisms also showed in vitro growth patterns in liquid media that appeared to be enhanced by the hormonal stimulation protocol used for oocyte retrieval. Elaborated cytokines within follicular fluid were also associated with adverse IVF

Abstract:

I used annual killifish Nothobranchius orthonotus to investigate two separate questions related to behavioural aspects of their life history. The first study focused on spatial cognitive ability of two N. orthonotus populations that originated from temporary pools that varied in their expected duration due to differences in annual precipitation patterns (dry and humid region). Test of cognition was based on the ability to learn to find food in a dichotomous test. It was assumed that learning ability differs between populations when tested in young and old age along with their difference in cap

Abstract:

Research Doctorate - Doctor of Philosophy (PhD)<br>Male infertility is a relatively common condition affecting 1 in 20 men of reproductive age. The aetiology of this condition is thought to involve the excessive generation of reactive oxygen species (ROS) by human spermatozoa; however the cause and sub-cellular origins of this aberrant activity is unknown. The objective of this doctoral thesis was to determine the importance of sperm mitochondria in creating oxidative stress associated with defective sperm function and subsequently to investigate causes of increased mitochondrial ROS generatio

Abstract:

Nowadays, a new concept of nanotechnology, “the nanomedicine” has been developed. Certain nanoparticles offer an exceptional set of characteristics that improve the diagnosis and treatment quality and efficacy on medicine. Zinc Oxide Nanoparticles (ZnO NPs) are a type of metal oxide nanoparticles with an extensive use, for example, in drug delivery systems, bioimaging and cancer therapy. Several authors have focused on biosafety studies of ZnO NPs, as their size and surface area favour the entrance and accumulation in organism, which can induce toxic effects. ZnO NPs have been identified, as a
