  1. 1. Isotope-based reconstruction of the biogeochemical Si cycle : Implications for climate change and human perturbation

    Författare :Xiaole Sun; Carl-Magnus Mörth; Christoph Humborg; Per Andersson; Brian Fry; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; diatoms; biogenic silica BSi ; dissolved Si DSi ; Si isotope fractionation; the Baltic Sea; geokemi; Geochemistry;

    Sammanfattning : The global silicon (Si) cycle is of fundamental importance for the global carbon cycle. Diatom growth in the oceans is a major sequestration pathway for carbon on a global scale (often referred to as the biological pump). LÄS MER

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; Salmo trutta; spawning; egg size; fry competition; fry dispersion; Biologi; Biology; Biologi; limnologi; Limnology;

    Sammanfattning : This thesis deals with how reproductive traits and reproductive behaviour in femalebrown trout (Salmo trutta) are linked to offspring performance.In the small stream Tullviksbäcken, the choice of spawning sites was stronglyinfluenced by short-term fluctuations in stream flow and by substrate quality.

It is argued that there has been a domestic dominance, with international factors a forgotten dimension. It is also argued that the limited body of work dealing with international factors has been empirical in nature. LÄS MER
