Bacteria Not An Energetically Favorable Food Source For Larvae Of Artemia Salina, Kenny Moore, William Jaeckle, Faculty Advisor
John Wesley Powell Student Research Conference
Larvae of the crustacean Artemia salina are reported to differentially ingest food particles of different sizes. We exposed 2-to-5-day-old A. salina larvae to equal volumetric concentrations (bead volume per mL) of 6 µm-diameter and 0.5 µm-diameter polystyrene beads. The clearance rate (volume cleared of particles per unit time) of each bead size was positively correlated with developmental stage of the larvae (r=0.598, p

Using Polystyrene Beads To Estimate Feeding Selectivity And Potential Energetic Consequences In The Rotifer, Brachionus Plicatilis, Stephen Little, William Jaeckle, Faculty Advisor
John Wesley Powell Student Research Conference
Rotifers are free-swimming aquatic animals that feed by collecting particles through the use of cilia that are arranged around the mouth in two circular whorls. Specimens of Brachionus plicatilis exposed to 6µm and 0.5µm polystyrene beads (together or separately) captured the particles at significantly different rates. Calculation of the Jacob's Selectivity Index (D) revealed a significant selectivity for the larger (6µm) beads, over the smaller (0.5µm) beads (pB. plicatilis revealed that bacteria are not likely a significant energy source. Bacterial concentration ≥ 108 cells/ml (100 x typical values) are necessary for feeding on bacterial to support at least 33% of …

The Potential Effects Of Eggshell Porosity On Brown-Headed Cowbird And Dickcissel Incubation Periods, Brittany Childs, Miranda Kiefer, Given Harper, Faculty Advisor, William Jaeckle, Facutly Advisor, Brian Peer, Faculty Advisor
John Wesley Powell Student Research Conference
The Brown-headed Cowbird (Molothrus ater) is a brood parasite that lays its eggs in nests of other species; the eggs are incubated and the offspring are then raised by the host. Grasslandnesting Dickcissels (Spiza americana) are commonly parasitized by Cowbirds. Cowbird eggs have been reported to hatch sooner than equivalently-sized host eggs, giving their hatchlings a competitive advantage over host offspring. Our study focused on the hypothesis that the apparent accelerated development of Cowbirds is caused by greater eggshell porosity which allows for increased availability of oxygen during incubation. The mean pore area of Cowbird eggshells …

Uptake And Assimilation Of Dissolved Organic Matter By Bosmina Longirostris (Crustacea: Cladocera), Nikki Preston, William Jaeckle, Faculty Advisor
Uptake And Assimilation Of Dissolved Organic Matter By Bosmina Longirostris (Crustacea: Cladocera), Nikki Preston, William Jaeckle, Faculty Advisor
John Wesley Powell Student Research Conference
A considerable amount of dissolved organic matter (DOM) exists in freshwater environments (5- 40 µ g/mL). However, freshwater invertebrates, including crustaceans, are viewed as incapable of taking up and metabolically utilizing DOM. We evaluated this hypothesis by exposing the freshwater crustacean Bosmina longirostris to labeled proteins and polysaccharides. Individuals readily ingested these materials as evidenced by the presence of molecule-specific labels in the digestive system. Histological examination of specimens exposed to the protein ferritin revealed that the label was in the lumen of the digestive tract but not in the surrounding cells. Digestion in crustaceans is extracellular, and the absence …
