Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

Taxonomic revision of Lichnanthe Burmeister with studies on the biology of L. rathvoni (Leconte) (Coleoptera:Scarabaeidae)

Creator:: Carlson, David Craig
Abstract:: The genus Lichnanthe Burmeister contains eight extant and one fossil species which are strictly nearctic in distribution. The subfamily Glaphyrinae, however, is distributed nearly world-wide. Five species were previously described and three are described as new herein. All eight extant species are described in detail herein, synonomies are made current,...

Factors affecting establishment, survival, and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.)

Creator:: Cooper, Clee Scott
Abstract:: Field, greenhouse, growth chamber and laboratory experiments evaluated factors affecting establishment, survival and production of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago sativa L.) Field studies investigated the effects of a barley companion crop, seedling year harvest management and nitrogen and phosphorus fertilization upon stands, survival and subsequent production...

Temperature and water potential effects on physiological functions of sudangrass (Sorghum vulgare var. Piper)

Creator:: Young, Richard Su-Shung
Abstract:: Temperature and water potential effects on the growth, transpiration, total nonstructural carbohydrate (TNC) content, and nutrient uptake of sudangrass (Sorghum vulgare var. piper) were investigated in laboratory experiments. The effect of nitrogen supply on the growth and nutrient uptake at constant soil water potential was also investigated in this study....

In situ Agrobiodiversity Conservation Planning in Centers of Origin: The Role of Culture

Creator:: Guerrero Ochoa, Isabel G.
Abstract:: Managing agricultural diversity ensures a range of public services, such as genetic resource diversity, food security for subsistence-based economies, and landscape resilience in the context of climate change, among others. These agrobiodiversity conservation services are positive externalities from agrobiodiversity conservation. Whereas their value is not captured in market transactions, management...

Exploring urban parks: plant communities, visitor experiences, and manager perspectives in Portland, Oregon

Creator:: Talal, Michelle L.
Abstract:: Urban parks are biodiversity hotspots within cities and have the potential to provide a range of socio-cultural benefits for people, but may not always meet the needs and desires of park visitors. A variety of land use practices and environmental factors affect urban park biodiversity and vegetation structure, composition, and...

The Influence of Alternate Life History Strategies and Natal Conditions on the Reproductive Performance of Adélie Penguins Breeding on Ross Island, Antarctica

Creator:: Kappes, Peter J.
Abstract:: A fundamental objective of ecology and population biology is to identify factors that drive population dynamics and determine the population-level consequences of their interaction with the environment. Studies of reproductive performance can illuminate population dynamic processes, including the links between organismal biology, the environment, and life history theory. A central...

Integration of Evolutionary Theory and Genomics to Understand Processes Involved in Host Adaptation and Divergence in Phytophthora Plant Pathogens

Creator:: Tabima, Javier F.
Abstract:: Modern plant pathology benefits from integrating methods and concepts from evolutionary biology. For example, evolutionary concepts are used to identify and examine species boundaries of plant pathogens, recognize processes underlying pathogen biogeography, identify traits that characterize emerging species, and discover new molecular interactions that originate under processes of selection. In...
