Reaching Modern Students Through Amazing Screencasts
Get PDFAre you frustrated with “one-shot” library sessions? Overcome this time limitation by creating great screencasts, allowing students to gain essential research skills at their own pace in their own place. You will learn how to create engaging screencasts and choose the best affordable screencasting software. Screencasting is a valuable addition to a librarian’s toolkit because:--Students have immediate access to research assistance--Content can be embedded in course management systems--It strengthens the library’s role in student and faculty research processes--It emulates a tiered reference model--Students can get to know librariansOur approach emphasizes the design of amazing screencasts using powerful software.Screencasting is a newer technique that librarians are using to deliver asynchronous library instruction. Unlike tutorials, these screencasts complement face-to-face interactions because students can develop prior knowledge of specific skills. This enhances library instruction and librarians can spend less time on basic information to focus on sophisticated research skills. Screencasts also extend learning outside of the classroom to reinforce skills taught in class. This workshop will help attendees focus their attention on the best approach to screencasts. First, we will provide some examples of exemplar screencasts. Then we will discuss what makes a “good” or “bad” screencast. Finally, we will spend most of the workshop in small groups creating screencasts
Reef Building Corals Rely on Symbionts over a Large Depth Range in an Internal Tidal Bore System, Florid Keys Reef Tract
Get PDFCorals living in shallow waters typically acquire their nutrients and energy from their photosynthetic symbiotic zooxanthellae, whereas deeper corals may rely to a lower extent on photosynthetic derived materials due to lower light levels. Whether these deeper corals feed to a greater extent is hotly debated within the community. Our study was based in the Florida Keys Reef Tract, which is unique because it is characterized by upwelling or tidal bores that periodically bring nutrient rich waters onto the Florida Shelf which can be used by benthic organisms. We separately measured the stable carbon and nitrogen isotope signatures of the coral host and symbiotic zooxanthellae of three species of reef building corals (Porites astreoides, Montastraea cavernosa, and Montastraea faveolata) along a depth gradient (3-35 m) in order to determine the feeding strategies of these corals as well as to assess whether corals were able to utilize upwelled water as a source of nutrients. The δ13C and δ15N values of the zooxanthellae and host tissue of all three species became progressively more depleted in 13C and 15N with depth, and δ15N values were strikingly low. The trend in the δ15N values with depth suggest that feeding is less important at depth. Further, we found a strong correlation between the δ13C values of the host and their zooxanthellae at all depths, suggesting that even as photosynthetic rates decrease with depth, hosts continue to acquire most of their carbon from their symbionts and do not rely to any greater extent on feeding heterotrophically. Finally we suggest that the strikingly low δ15N values for deep water corals are due to the utilization of upwelled water as a source of nutrients
Chemical attractants of Philornis downsi [Diptera: Muscidae], an invasive parasite of birds in the Galapagos Islands
Get PDFits discovery in 1997, Philornis downsi has been shown to significantly reduce fledgling success in many bird species within the Galapagos Islands, including endemic and critically endangered species of Darwin’s finches. Despite the level of impact on such highly celebrated birds, there are currently no practical methods of controlling or monitoring P. downsi populations. This study was designed to explore the potential of chemical ecology to remedy these needs. During the month of February 2012 on the Galapagos island of Santa Cruz, we measured the attractiveness of two prospective P. downsi olfactory cues using different designs of baited traps. We evaluated three trap designs for effectiveness. The results indicated cylindrical sticky traps are less effective than McPhail traps in catching P. downsi and horizontal flat sticky traps are not effective at all. While simultaneously testing trap designs, the attractiveness of nest-related odors and fly-produced pheromones were evaluated using lures of dichloromethane extracted host nest headspace volatiles and male/female deceased flies, respectively. Traps baited with nest odors were not attractive in comparison to positive or negative controls (n=7). The testing of pheromonal sources of P. downsi attraction showed that neither male baited traps, female baited traps, nor unbaited traps were able to catch any specimens (n=5). While the ultimate goal of this study, to support the potential for an efficient olfactory-based method of monitoring and controlling P. downsi, was not met, experimental techniques and design details were refined for future investigation of P. downsi chemical ecology

Impacts of Lime Treatment on Trout Ponds in the Five Ponds Wilderness of the Adirondack Park
Get PDFAddition of calcium carbonate (CaCO3) to lakes in the form of agricultural limestone is a management technique used in the Adirondack Park in New York State to mitigate the effects of acidic precipitation on aquatic ecosystems. We used a combination of in situ and laboratory experiments as well as field sampling of two neighboring ponds in the Five Ponds Wilderness with different liming histories to test whether the application of limestone can have significant effects on survivorship and community composition of aquatic organisms. Within in situ mesocosms or laboratory microcosms survivorship was decreased for crustacean zooplankton, amphipods and odonata nymphs at concentrations of one ton per surface acre of lime and higher; the New York State Department of Environmental Conservation (NYSDEC) applies lime at one ton per surface acre. Tamarack Pond has been managed by lime addition and brook trout stocking and the aquatic insect community is significantly different than that of Slender Pond, which has never been limed or stocked, even though the two ponds share a water source. This difference may be attributable to predation impacts of fish on aquatic insects, making the link between liming and insect faunal compositions difficult to determine. This study suggests the short term impacts of lime treatment on biota may affect the biotic community of aquatic ecosystems on a longer time scale, and may need to be considered before a liming program is started. Including the volume of a body of water to be limed when determining lime additions would be an inexpensive way to limit the impact that treatment would have on the aquatic ecosystems of the Adirondack Park
