Abstract:

The tallgrass prairie has been severely reduced in size, making restoration important to maintain communities and functions of this ecosystem. A chronosequence approach was used to determine recovery of physical and biological soil properties. The recovery models of soil properties provided information to explain the variation in total C stock of the whole soil. Recovery models also provided information to design a competition experiment based on variation in whole soil conditions with land use history. The filter framework hypothesis is a useful concept for examining tallgrass prairie restora

Abstract:

This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events. Depending on the spatial level, local or global, suitable methods are different. The thesis consists of four papers. The first explores the spatial genetic structure in two epiphytic bryophytes that have different dispersal strategies (Orthotrichum speciosum and O. obtusifolium) using three diffe

Abstract:

In this thesis, enzymes acting on the primary cell wall hemicellulose xyloglucan are studied. Xyloglucans are ubiquitous in land plants which make them an important polysaccharide to utilise for microbes and a potentially interesting raw material for various industries. The function of xyloglucans in plants is mainly to improve primary cell wall characteristics by coating and tethering cellulose microfibrils together. Some plants also utilise xyloglucans as storage polysaccharides in their seeds. In microbes, a variety of different enzymes for degrading xyloglucans have been found. In this

Invasive exotic species threaten native biodiversity, alter ecosystem structure and function, and annually cost over $100 billion in the US alone. Determining the ecological traits and interactions that affect invasion success are thus critical for predicting, preventing, and mitigating the negative effects of biological invasions. Native herbivores are widely assumed to facilitate exotic plant invasions by preferentially consuming native plants and avoiding exotic plants. Here, I use freshwater plant communities scattered broadly across the Southeastern U.S. to show that herbivory is an impor

Abstract:

In the eastern U. S. and other wheat growing areas of the world, powdery mildew is a major constraint to the production of wheat. Currently, the most effective and economical means of control is to use resistant cultivars. Unfortunately, the diversity of the pathogen population enables the pathogen to overcome new resistance genes, often within several seasons of commercial deployment. Surveys to determine the virulence of the population to a set of resistance genes have been performed in many areas of the world. Often, differential frequencies of virulence at varying geographic areas are exte

This is contrasted with a hypothesis that predicts positive plant-plant interactions in high alpine environments.

Abstract:

Nitrilases (EC 3.5.5.1) catalyse the enantioselective hydrolysis of a variety of organic nitriles to the corresponding amide and/ or carboxylic acid. These reactions are important in the manufacture of fine chemicals, pharmaceutical intermediates, plastics and paints. Industrial uses of nitrilases are limited however, as wild-type enzymes suffer from limitations such as: a lack of control of the acid:amide ratio of products, and limited availability of substrate specificities.

The study was carried out at in a subarctic alpine area (Kilpisjärvi 69°01'N 20°50E', Finland). Seed bank and seedling densities were high in many plant communities (ranges 99 -1109 viable seeds/m2 and 0.2-227 seedlings/m2, respectively).
