1. Multistressors Related to Climate Change and Their Effects on Global Biodiversity during the Cenozoic Age
University essay from Lunds universitet/Miljövetenskaplig utbildningAbstract : As multistressors have been shown to have significant effects on biodiversity and ecosystem functioning, the following study was made with the purpose of examining how a number of stressors specifically connected to climate change may have varied during the latest 65,5 million years and whether it is possible to predict potential effects on global biodiversity in the future. The analyses focused on global species richness during the Cenozoic age along with variables such as variations in atmospheric CO2, sea surface temperatures and global sea levels derived from analyses of various stable isotopes found in marine sediments.

2. Species and Biological Diversity - Choices of Diversity Indices and their Potential Consequences for Nature Conservation
University essay from Lunds universitet/Miljövetenskaplig utbildningAbstract : As there currently are not so many known studies which directly evaluate how diversity indices have been used in different contexts, following literature study was made with the purpose of investigating how three of the most commonly used diversity indices (including Shannon-Wiener’s and Simpson’s Indices as well as a certain index measuring taxonomic diversity) are representing different categories of species in scientific reports and articles through an environmental scientific point of view. In order to find a possible explanation to the potential relations between the individual choice of diversity index as well as the substantial conservation of species and biological diversity in general, 50 reports and articles, which all had in common that they had species or biological diversity as their main topic as well as which included the use of any of the diversity indices chosen in this study, were randomly chosen through a single sample.
