Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Socialist Rags to Capitalist Riches relates the events of David Lloyd's childhood and youth in the United Kingdom through the dark days of economic and social problems caused by shifting forces in a battle for ultimate power.His life story and his coming to America to pursue the riches of freedom should sound an alarming wake-up call. His insight and the intervention of almighty God in his life lead to solid truth for a world struggling to contend with its fragile humanity.The American proponents of socialistic theories and extreme liberal ideologies are taking radical steps to drastically change the course of America in the name of progress.Many in the United States are eager and willing to follow influential voices towards a false scenario. These liberal pied pipers will not disclose the dangerous, unaffordable, and unsustainable future for us and those who follow for years to come.
