The main goal of this thesis is to increase understanding on evolutionary and ecological factors that have contributed to differences in parasite numbers in insects. Furthermore, the thesis addresses the effects of parasites ...

Plants form the first trophic level in terrestrial ecosystems and provide energy and nutrients to higher trophic levels. Herbivores, frugivores or fungal endophytes use plants directly, while ...

A common feature of natural populations is that individuals differ in morphology, physiologyand behavior (<i>i.e</i> .phenotype). A thorough understanding of the molecular mechanisms and evolutionary forces behind this ...

Jatropha curcas (L.) is a multipurpose oil bearing shrub assumed to be able to survive in a wide range of ecological conditions across the tropical regions of the world. The thesis is composed of two parts, the first one ...

In this thesis, different genetic tools are used to investigate both natural variation and speciation in the Ficedula flycatcher system: pied (<i>Ficedula hypoleuca</i>) and collared (<i>F. albicollis</i>) flycatchers. The ...

In oxygen-evolving photosynthesis, the balanced excitation of photosystem (PS) I and PSII complexes is required for safe and efficient utilization of light energy. During the course of evolution, plants have acquired dynamic ...

During the past few years, a considerable number of research articles have been published relating to the structure and function of the major photosynthetic protein complexes, photosystem (PS) I, PSII, cytochrome (Cyt) ...

There are more than 7000 languages in the world, and many of these have emerged through linguistic divergence. While questions related to the drivers of linguistic diversity have been studied before, including studies with ...

Bumblebees are a very essential group of pollinating insects, but their populations have declined drastically during the past decades. We need to understand why their numbers are decreasing and what can be done to reverse ...
