Abstract:

A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. Garpenberg is such a location hence this thesis, which aims to quantify the factors governing spectrophotometric lightness in marble at the Dammjön ore body. The work is mainly based on five drill cores which were logged and sampled. A total of twenty-seven samples were characterized using lit

A variety of cetacean species make use of the bays along the South African coast for different purposes, including feeding, mating and calving.

Abstract:

Sexual reproduction and the production of seeds are important for the resilience of all angiosperm species. For clonal species, such as the seagrass Zostera marina, resource allocation is complicated because these species reproduce both asexually and sexually, and the factors contributing to allocation to these two processes remains unknown. The goal of this study was, therefore, to investigate the importance of critical light, nutrient, and rhizome resources on Z. marina sexual reproduction and flowering intensity.

Few studies of tropical fish communities compare fish distributions across the full range of near-shore tropical marine habitats. As a result, our understanding of tropical marine fish communities is often biased towards habitats preferred by researchers. The distribution and habitat preferences of all 136 fish species occurring at 106 stations in three bays off Tortola in the British Virgin Islands were assessed. At a species level, habitat type was often the key factor influencing fish distribution. Of the 44 species occurring at more than 10 stations, 3 were sand specialists, 5 were strongl

Abstract:

Abstract Recognition of the importance of a regional perspective for understanding the structure and dynamics of local assemblages has stimulated the emergence of the field of macroecology. Most attention has been directed to terrestrial ecosystems, while large-scale patterns in biodiversity of aquatic organisms have received less attention. In this thesis I examined patterns of aquatic diversity across several geographic areas and scales, in an effort to understand some of the environmental and spatial factors determining species diversity in aquatic environments. The main objectives of this

Abstract:

O objetivo do presente trabalho é analisar a influência de fatores ambientais na ocorrência e a distribuição espaço-temporal de cladóceros marinhos em uma região estuarina rasa localizada junto a uma área de manguezal. Ao longo do período de julho de 2004 a junho de 2005, foram realizadas amostragens do zooplâncton durante as marés enchentes de sizígia em duas estações de coletas localizadas na Praia Dura, município de Ubatuba, SP. As amostragens foram realizadas em triplicatas por meio de arrastos horizontais utilizando-se uma rede cônica com fluxômetro acoplado para se determinar o volume de

Abstract:

Growth performance in vertebrates is regulated by environmental factors including the quality and quantity of food, which influences growth via endocrine pathways such as the growth hormone (GH) / insulin-like growth factor somatotropic axis. In several teleost fishes, circulating concentrations of insulin-like growth factor-1 (Igf1) correlate positively with growth rate, and it has been proposed that plasma Igf1 levels may serve as an indicator of growth variation for fisheries and aquaculture applications. Here, I tested whether plasma Igf1 concentrations might serve as an indicator of somat

Abstract:

High-Performance Marine Craft (HPMC) is a complex system confronted by the stochastic nature of the waves challenging the safety of life at sea. The personnel aboard these craft are vulnerable to detrimental conditions, in fact, limiting the system’s performance evoking the significance of the Human Factors Integration (HFI) in the design and operation of these craft. The risks related to the work environments at sea have inadequately been investigated. A consistently identified fact is that the exposure to work environments containing vibration and repeated shock elevates the risk of adverse
