Arkansas was purchased from France as part of the Louisiana Purchase in 1803. Parts of it were explored by the Dunbar and Hunter expedition in 1804-05. ln 1819, it was detached from the Missouri Territory and made a separate territory. By 1821, the capital moved to Little Rock, and on June 15, 1836, Arkansas became the 25th state of the United States of America. The Arkansas Game and Fish Commission was established on March 11, 1915, and the first "real" law pertaining to game hunting was passed. The commission started to establish game refuges in 1929, and by 1960, it …

The Pollination Biology And Mating System Of A Peripheral Population Of Witheringia Solanacea (Solanaceae), Timothy Miller
Honors Theses
Pollinator visitation rates over the life of a flower are determined by pollinator abundance and floral longevity. If flowers are not visited frequently enough, pollen limitation may occur, favoring the evolution of self-compatibility (SC). In plant species with varying SC levels, central populations often are self-incompatible (SI) and peripheral populations are SC. Witheringia solanacea (Solanaceae) is a species that follows this trend with the exception of one population in the Monteverde Cloud Forest Reserve, which is peripheral yet SI. I investigated this population using multiple techniques including floral bagging, pollinator observations, microsatellite analysis, and floral longevity manipulations. My results confirmed …
