Abstract

Science communication and university Extension initiatives are evolving in response to society's needs and an ever-changing digital landscape. The UF/IFAS Center for Aquatic and Invasive Plants (CAIP) has recently launched a podcast called Working in the Weeds (WITW). We surveyed podcast listeners to find out their motivations for listening and asked for their feedback on current episodes and future content. The survey revealed that a majority of respondents were individuals who work in the world of invasive plants. Many respondents were introduced to the podcast through work and listen to learn more about relevant research and information, to feel connected to the Center, and to be entertained. Overall, the respondents were satisfied with the podcast production elements and the variety of episode styles. Based on open-ended responses, listeners described that the podcast shares science in a meaningful way and the Center should continue producing episodes that highlight invasive plant research. Some respondents suggested future episodes should cover specific invasive plants, environmental impacts, herbicide use and safety, management techniques, and social issues surrounding invasive plant management.

Abstract

An echelle spectrogram (R = 30,000) of the 2300-3100 A region in the ultraviolet spectrum of the F8V star 9 Comae is presented. The observation is used to calibrate features in the mid-ultraviolet spectra of similar stars according to age and metal content. In particular, the spectral break at 2640 A is interpreted using the spectral synthesis code SYNSPEC. We use this feature to estimate the time since the last major star formation episode in the z=1.55 early-type galaxy LBDS 53W091, whose rest frame mid-ultraviolet spectrum, observed with the Keck Telescope, is dominated by the flux from similar stars that are at or near the main-sequence turnoff in that system (Spinrad et al. 1997). Our result, 1 Gyr if the flux-dominating stellar population has a metallicity twice solar, or 2 Gyr for a more plausible solar metallicity, is significantly lower than the previous estimate and thereby relaxes constraints on cosmological parameters that were implied by the earlier work., Comment: 8 pages, Latex, 6 figures.
