Exposure to increased diversity has been found to produce beneficial results in both learning and democracy outcomes across races; however, this relationship is more consistent for White students than students of color (Gurin, Dey, Hurtado, & Gurin, 2002). Using the data from a campus-wide diversity survey, the relationship between two types of diversity (informal-interactional and classroom) with learning and democracy outcomes was examined in a mid-sized university. Additional analyses were conducted to identify trends in diversity attitude and perception of campus climate toward diversity. Increased classroom diversity and informal-interactional diversity were both found to be related to increased learning and democracy outcomes for White students. For students of color, only classroom diversity was related to increased learning and democracy outcomes. Students of color and females were found to possess more positive attitudes toward diversity. Students of color perceived the more negative campus diversity climate than did White students.

Floral visitation alone has been typically used to characterize plant-pollinator interaction networks even though it ignores differences in the quality of floral visits (e.g. transport of pollen) and thus may overestimate the number and functional importance of pollinating interactions. However, how network structural properties differ between floral visitation and pollen transport networks is not well understood. Furthermore, the strength and frequency of plant-pollinator interactions may vary across fine temporal scales (within a single season) further limiting our predictive understanding of the drivers and consequences of plant-pollinator network structure. Thus, evaluating the structure of pollen transport networks and how they change within a flowering season may help increase our predictive understanding of the ecological consequences of plant-pollinator network structure. Here we compare plant-pollinator network structure using floral visitation and pollen transport data and evaluate within-season variation in pollen transport network structure in a diverse plant-pollinator community. Our results show that pollen transport networks provide a more accurate representation of the diversity of plant-pollinator interactions in a community but that floral visitation and pollen transport networks do not differ in overall network structure. Pollen transport network structure was relatively stable throughout the flowering season despite changes in plant and pollinator species composition. Overall, our study highlights the need to improve our understanding of the drivers of plant-pollinator network structure in order to more fully understand the process that govern the assembly of these interactions in nature.
