Abstract:
There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. This gives a relatively short distance between ingroup (eukaryotes) and outgroup (mitochondrial progenitor), which is important for accurate rooting. The resulting phylogeny reconstructs three eukaryote megagroups and places one, Discoba (Excavata), as sister group to the other two (neozoa). This rejects

L'origine des eucaryotes est un problème important de la biologie évolutive, pour lequel de nombreuses hypothèses profondément différentes ont été proposées. L'une des stratégies majeures, pour discriminer ces hypothèses, est d'utiliser le fait qu'elles sont associées à des prédictions distinctes quant aux arbres phylogénétiques qui devraient être observés pour les gènes communs aux eucaryotes et aux archées ou aux eucaryotes et aux bactéries.

Abstract:
The Lemon Tree is a collection of poems that arose from my attempt to capture memories of influential experiences in growing up. The poems are written in prose blocks and move in and out of childlike and adult sensibilities, creating the disillusion of time and memory. The poems themselves are comments on the unreliability and limited scope of memory and compare remembrance to dreams. This suggests that time moves more fluidly than the waking world accepts. Through looking back, through prisms, the speaker remembers experiences that impacted her development as we follow her on a journey to com

BACKGROUND:Scientists rarely reuse expert knowledge of phylogeny, in spite of years of effort to assemble a great "Tree of Life" (ToL). A notable exception involves the use of Phylomatic, which provides tools to generate custom phylogenies from a large, pre-computed, expert phylogeny of plant taxa. This suggests great potential for a more generalized system that, starting with a query consisting of a list of any known species, would rectify non-standard names, identify expert phylogenies containing the implicated taxa, prune away unneeded parts, and supply branch lengths and annotations, resul

Like few other concepts in the history of science, Darwinian evolution prompted humans to question their most basic assumptions about themselves.

To investigate major evolutionary trends and the importance of fossil data we need to be confident that both phylogenetic trees and fossil dates are reliable.

I used both simulated data and a large sample of empirical trees to determine the effect of these biases on the most widely used indices of stratigraphic congruence to determine.

Abstract:
Artificiella ekosystem är en tillämpning av artificiell intelligens som har funnits länge. Användningsområden för artificiella ekosystem innefattar främst biologiska simulationer men även andra typer av simulationer förekommer. Genom att simulera individuella djur blir den artificiella intelligensens uppgift att styra djurens beslut utifrån dess individuella förutsättningar och kamp för överlevnad. Detta arbete behandlar frågeställningen vilken beslutsalgoritm som är bäst lämpad att för att använda till ett artificiellt ekosystem i ett spel. Två beslutsalgoritmer jämförs, en dynamisk som bygge

Abstract:
In the late 90s coconut farms in Mozambique were affected by a disease that made the coconut trees drop their leaves and die, the disease is called the coconut lethal yellowing disease (CLYD). It is known that planthoppers are spreading the disease. This thesis investigates if cultivation and farm related factors could have an impact on the risk of being infected by CLYD. With a sample of 534 farms from the two provinces Zambeze and Nampula a logistic regression model is estimated. The result shows that the only factor that has a significant effect of increasing the risk of getting infected by

Abstract:
Traditionally manufacturing job shops either have a process layout or a product layout. The advantages of one type of layout tend to be a disadvantage for the other. Hybrid cellular constructs represents a novel fusion of process and product layouts. In this thesis, hybrid cellular constructs specifically Hybrid Flow Shops and Reoriented andamp; Reshaped Cells are clearly described in terms of their structure, key features, and modes of operation. An engineering procedure is illustrated by cases and particular manufacturing circumstances where each concept would be most useful are identified.

Abstract:
Over the last two decades, mountain pine beetle (Dendroctonus ponderosae) populations reached epidemic levels across much of western North America, including high elevations where cool temperatures previously limited beetle persistence. Many high-elevation pine species are susceptible hosts and experienced high levels of mortality in recent outbreaks, but co-occurring Great Basin bristlecone pine (Pinus longaeva), the longest-living non-clonal organism, were not attacked. I assessed Great Basin bristlecone pine resistance to mountain pine beetle by evaluating mountain pine beetle host selectio
