Comparison Of Dna Methylation In Vibrio Vulnificus Cells Grown In Human Serum With Those Grown In Seawater, James W. Conrad, Valerie J. Harwood

Integrative Biology Faculty and Staff Publications

The chromosomal methylation statuses of the highly virulent Vibrio vulnificus strain CMCP6 grown in human serum and in seawater are compared here. Growth in seawater resulted in ∼4 times as much methylation as that in human serum, primarily N⁴-methylcytosines.

A Ctenophore (Comb Jelly) Employs Vortex Rebound Dynamics And Outperforms Other Gelatinous Swimmers, Brad J. Gemmell, Sean P. Colin, John H. Costello, Kelly R. Sutherland

Gelatinous zooplankton exhibit a wide range of propulsive swimming modes. One of the most energetically efficient is the rowing behaviour exhibited by many species of schyphomedusae, which employ vortex interactions to achieve this result. Ctenophores (comb jellies) typically use a slow swimming, cilia-based mode of propulsion. However, species within the genus Ocyropsis have developed an additional propulsive strategy of rowing the lobes, which are normally used for feeding, in order to rapidly escape from predators. In this study, we used high-speed digital particle image velocimetry to examine the kinematics and fluid dynamics of this rarely studied propulsive mechanism. This mechanism …

College science instructors need continuous professional development (PD) to meet the call to evidence-based practice. New PD efforts need to focus on the nuanced blend of factors that influence instructors’ teaching practices. We used persona methodology to describe the diversity among instructors who were participating in a long-term PD initiative. Persona methodology originates from ethnography. It takes data from product users and compiles those data in the form of fictional characters. Personas facilitate user-centered design. We identified four personas among our participants: Emma the Expert views herself as the subject-matter expert in the classroom and values her hard-earned excellence in …

Multiscale Model Of Regional Population Decline In Little Brown Bats Due To White-Nose Syndrome, Andrew M. Kramer, Claire S. Teitelbaum, Ashton Griffin, John M. Drake

Integrative Biology Faculty and Staff Publications

1. The introduced fungal pathogen Pseudogymnoascus destructans is causing decline of several species of bats in North America, with some even at risk of extinction or extirpation. The severity of the epidemic of white-nose syndrome caused by P. destructans has prompted investigation of the transmission and virulence of infection at multiple scales, but linking these scales is necessary to quantify the mechanisms of transmission and assess population-scale declines.
2. We built a model connecting within-hibernaculum disease dynamics of little brown bats to regional-scale dispersal, reproduction, and disease spread, including multiple plausible mechanisms of transmission.
3. We parameterized the model using the approach of …

The Caricomp Network Of Caribbean Marine Laboratories (1985–2007): History, Key Findings, And Lessons Learned, Jorge Cortes, Hazel A. Oxenford, Brigitta I. Van Tussenbroek, Eric Jordan-Dahlgren, Aldo Croquer, Carolina Bastidas, John C. Ogden

Caribbean Coastal Marine Productivity (CARICOMP) was a basin-wide cooperative, international network of marine laboratories established in 1985. Recognizing major trends of change in coastal ecosystems and the importance of the linkages among them, our goal was to monitor synoptically with standardized methods the physical environment and to document trends in measures of the structure and functioning of coral reefs, seagrasses and mangroves. Between 1985 and 1993, the CARICOMP Steering Committee established a data management center and wrote a methods manual. Marine laboratories joined the program by appointing a Site Director and signing an agreement specifying the cost sharing and responsibilities …
