Biological Sciences Faculty Publications and Presentations

Species identification plays a significant role in biodiversity conservation. As many species remain unrecognized, particularly in neotropical hotspots like the Brazilian Atlantic Forest (AF), novel molecular techniques are being widely employed to bridge this gap. In this study, we used DNA barcoding and phylogenetic tools to identify a new population of Sphaenorynchus canga in the central region of the Brazilian AF. Our results extend the species’ known distribution by approximately 200 km to the south, encompassing a different mountain range than its type locality (Serra do Espinhaço). This disjunct distribution, while not uncommon among amphibians, suggests a historical connection between …

How Chatbots Augment Human Intelligence In Customer Services: A Mixed-Methods Study, Xiaolin Lin, Xuequn Wang, Bin Shao, Joseph Taylor

Research outputs 2022 to 2026

Although artificial intelligence (AI)-enabled chatbots have been increasingly incorporated into firms’ business processes, such as customer service, they are still ineffective at handling unstructured tasks. Therefore, organizations might adopt chatbots to cut down the workforce for structured tasks and augment the remaining employees in unstructured tasks. Although there are substantial workforce implications for rebalancing work activities, few studies have assessed chatbots from the augmentation angle by focusing on employees’ performance, perhaps because of the lack of a theoretical foundation and research on this new phenomenon within organizations. Using a mixed-methods design, we developed a model illustrating the impact of chatbots …
