The freshwater mussel populations in the lower stretch of Big Walnut Creek in central Ohio have been found to vary along the run of the creek with the lowest population of mussels in the middle stretch. One possible cause for the decline is the presence of contaminants in the sediments of the creek. In this study, nine Sites along the creek were examined. At each Site, sediment samples from a pool region and two quadrants from where mussels were also studied (the area of interest) were collected, along with pseudo feces, which is the waste mussels produce as they filter …
Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson
Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson
Undergraduate Distinction Papers
Although giant pandas (Ailuropoda melanoleuca) are known to be solitary in the wild, cubs engage in frequent bouts of affiliative behavior in captive settings. The goal of the project was to investigate whether kinship or familiarity based on housing influenced the frequency of social interactions within one-year old giant panda cubs. Data were collected from June through mid-July 2016 at the Chengdu Research Base of Giant Panda Breeding, Sichuan, China. Over 113 hours of behavioral observations were recorded on four sets of twins and one singleton, focusing specifically on affiliative behaviors. Time housed together was a significant predictor of the …
Ecological Correlates With Dioecy In The Flora Of A Tropical Premontane Wet Forest In Costa Rica., Breanne Held
Ecological Correlates With Dioecy In The Flora Of A Tropical Premontane Wet Forest In Costa Rica., Breanne Held
Undergraduate Distinction Papers
There is a considerable disagreement about the selective forces that have led to the evolution of dioecy (i.e., the condition of having separate male and female flowers on separate plants). Historically, selection to enforce outcrossing has been the primary explanation despite there being little empirical evidence. Hence, many scientist argue that the selection of dioecy is driven by ecological traits that influence male and female fitness and seed dispersal. The objective of this study was to examine the association between plant sexual system (particularly, dioecy) with various ecological traits for the flora of a tropical premontane wet forest in Costa …
A Reexamination The Freshwater Mussels (Family Unionidae) In Lower Big Walnut Creek, Kierra M. Lathrop
A Reexamination The Freshwater Mussels (Family Unionidae) In Lower Big Walnut Creek, Kierra M. Lathrop
Undergraduate Distinction Papers
Freshwater mussels (family Unionidae) have become increasingly rare as the threats to water quality, habitat quality, and other aquatic animals, which the mussels depend on, have increased. The absence of mussels can provide evidence that one of these factors is insufficient. Lower Big Walnut Creek (BWC) is known to support a diverse community of mussels but they are unevenly distributed throughout the creek with abundance, density, and richness being high in the upper section, very low in the midsection, and intermediate in the lower section. It has been suggested water quality nor symbiotic fish host communities are responsible for this …
