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:

Aviation has the capacity to drive changes in atmospheric composition, and therefore climate and air quality, increasing human mortality through increases in cases in cardiopulmonary disease. Non-CO2 aviation emissions are estimated to have a considerable effect on the climate, and with rapid growth in the aviation sector their associated impacts could increase. There is much uncertainty surrounding the climatic impact of aviation-induced ozone and aerosols, in part due to broad range of emissions species emitted, which are not always reported in aviation emissions inventories.

Abstract:

Predictions of species’ ranges from distribution modeling are often used to inform marine management and conservation efforts, but few studies justify the model selected or quantify the uncertainty of the model predictions in a spatial manner. This thesis employs a multi-model, multi-area SDM analysis to develop a higher certainty in the predictions where similarities exist across models and areas. Partial dependence plots and variable importance rankings were shown to be useful in producing further certainty in the results. The modeling indicated that glass sponges (Hexactinellida) are most l

Abstract:

Herbaceous perennials represent a considerable portion of potential biomass feedstocks available for the growing bioenergy industry. Their chemical composition and biomass yields, which are important in determining ethanol potential on an area and mass basis, vary with plant variety and type, environment, and management practices. Therefore, a study was conducted to assess the variability of lignin and carbohydrate content, biomass yields, and theoretical ethanol yields on an area basis among different herbaceous perennial species combinations grown in Minot (2008) and Williston (2008, 2009, a

Abstract:

This thesis explores and proposes methods to improve species distribution models. Throughout this thesis, a rich class of statistical modelling techniques has been developed to address crucial and interesting issues related to the data input into these models. The overall contribution of this research is the advancement of knowledge on species distribution modelling through an increased understanding of extraneous zeros, quality of the ecological data, variable selection that incorporates ecological theory and evaluating performance of the fitted models.

A área de pesquisa denominada Informática para Biodiversidade enfrenta o desafio de suprir a demanda por tecnologia de apoio à conservação da biodiversidade. Dentre as áreas da ecologia que se beneficiam de recursos tecnológicos, a modelagem de distribuição de espécies se destaca pelo número de ferramentas e de algoritmos desenvolvidos para os pesquisadores da área. No entanto, estudos demostram que a modelagem tem se tornado mais complexa, bem como, a necessidade por melhorias da aplicação de novas técnicas e soluções computacionais.

Abstract:

Recently, examination of deoxyribonucleic acids in water samples (environmental DNA or eDNA) has shown promise for identifying fish species present in water bodies. In water, eDNA arises from bodily secretions such as mucus, gametes, and feces. I investigated whether eDNA can be effective for characterizing fish presence, relative abundance, biomass, and species composition in a large Arizona reservoir (Theodore Roosevelt Lake) and 12 small Arizona (<24 ha) waterbodies. Specifically, I compared fish presence, relative abundance (catch per unit effort [CPUE]), biomass (biomass per unit effort [

Abstract:

Research in the multidisciplinary science of ecotoxicology is crucial to assess injuries to ecosystem resources from chemical spills or other stressors used to support environmental decision-making. Established guidelines recommend the use of non-standard native species in toxicity investigations. This work focused on the use of native species for aquatic toxicity assessment to make more relevant conclusions on the potential for adverse biological effects to occur as a result to single chemical exposures or exposures to a complex mixture like oil. We apply these studies to investigate petroleu

In this study the ecology, biology and classification of the sea cucumber species of the Red Sea coast of Egypt and Gulf of Aqaba were examined in order to resolve some of the long standing question on the identification and classification of sea cucumber.The introduction of the new barcoding technique as a tool for sea cucumber identification was also tested in this study in order to assess its accuracy and potential of the technique in identifying sea cucumber individuals. A total of 18 different (species) of sea cucumber were collected from the Egyptian coast and examined for both morpholog
