Promoting Amphibian Conservation through the College Classroom: Detection of Batrachochytrium dendrobatidis among Local Amphibians

Many global amphibian declines have been linked to the fungal pathogen Batrachochytrium dendrobatidis (Bd). The knowledge on Bd distribution provides a fundamental basis for amphibian conservation planning. Yet, such Bd distribution information is currently insufficient, in particular at a regional scale. The college classroom provides an excellent opportunity to expand the knowledge of Bd distribution. Here we provide an example of such research projects to detect Bd prevalence among local amphibians in a college course setting and present the results of work conducted in central Pennsylvania, USA. We collected toe clips and conducted PCR assays of six species, Plethodon cinereus, Desmognathus fuscus, Notophthalmus viridescens, Lithobates catesbeianus, L. clamitans, and L. sylvaticus (59 individuals). Four groups of students independently conducted entire projects, orally presented their findings, and submitted manuscripts to the professor at the end of the semester. This example demonstrates that it is feasible for an undergraduate class to complete a Bd-detection project within a single semester. Such a project not only contributes to Bd research but also promotes conservation education among students through hands-on research experiences. We found Bd infection in only one sample of N. viridescens, but no sign of infection in the rest of the samples. As a relatively high prevalence of Bd has been reported in surrounding areas, our results suggest spatial heterogeneity in Bd occurrence at a regional scale and thus, the need for continued efforts to monitor Bd prevalence.

The Daughters of Bridget McGhee

When Huxley proposed, Blythe imagined herself fifty years into the future at his funeral. He was such a good man, they’d say. Seventy-two is too young, they’d say. She’d nod and, she had imagined, remember this moment – them lounging in her bed during the early afternoon with the sunlight threatening to burst from behind the drawn shades, him lying on his side with his left arm anchored around her waist, and the tickle of his thumb as he traced circles on her bellybutton. She rubbed her nose against his neck and breathed. His scent was different from that of Walter. Huxley smelled of pears and basil. Walter smelled of leather and soap. She didn’t smell Walter intentionally, of course. He walked into the White Dog the prior day while she was drinking a mint-mocha cappuccino and studying for an exam on medical physiology. The wind whiffed his odor towards her. She didn’t look at him, but she couldn’t stop from inhaling. “People get married after college,” Huxley swung his right leg over and straddled her, forcing her to look at him. “It’s almost been a year since we graduated. It’s what we should do.” She had wondered if he could donate organs if he were seventy-two years old. Not his liver or heart or anything like that, of course, but maybe his eyes. It’d be a shame if they couldn’t preserve his eyes. She noticed them first: they were alert and misty blue, like Santa’s. But then she wondered if eye characteristics like color were even changed during cornea transplants. Walter had plain brown eyes. She hated brown eyes. She told people that she had brown eyes, because they were dark and no one ever looked close enough. Except Huxley. They were at dinner with mutual friends and were talking about eye color, and how they all wished that theirs were like those of the young Afghan girl on the 1985 cover of National Geographic.
