Mathematical modeling is used to investigate control of the invasive aquatic plant Myriophyllum spicatum L. by the native watermilfoil weevil Euhrychiopsis lecontei Dietz. An age-structured population model with discrete development class is used to separate the destructive activity of Euhrychiopsis lecontei Dietz larvae from the relatively benign activity of the other developmental stages. Empirical model behavior is evaluated and agrees with expected system characteristics. Simulation results demonstrate diminishing returns in the control impact of E. lecontei Dietz as a function of population stocking density. These results indicate that predictive modeling of this type may be used to optimize the utilization of Euhrychiopsis lecontei Dietz as a biological control agent.
Professional societies play a unique role in our personal and professional lives as spaces for connection and as regulatory entities. Often composed of volunteers from a variety of backgrounds, professional societies can guide the cultural norms and expectations of an industry by acting as critical leaders for supporting diversity, equity, and inclusion initiatives. The present manuscript explains how professional societies, like the Organization of Biological Field Stations (OBFS), can embrace transdisciplinary approaches to create more inclusive (in)tangible spaces to address serious problems facing industries today. Climate change, sexism, and racism, are examples of “wicked” problems that cannot be solved using existing modes of inquiry and decision making because of their complex and interrelated nature. As members of OBFS, a professional society dedicated to the advancement of field-based research, we explain how transdisciplinarity can and has been used to begin addressing serious issues like racism and sexism in field-based research and provide steps for future professional societies to engage in transdisciplinary thinking. We close with examples of our own transdisciplinary work developed through our membership within OBFS.
Students were engaged in a combination of detective work, biology, archives, art, and education/outreach to prepare a collection of taxidermied birds donated to the University of Akron by the Rhodes family in the early 1900s for public access and exhibition. Students had the opportunity to learn from leading experts regarding the historical significance of biological collections, proper preservation protocols, digitizing and archival practices, and the urgency of science education and communication for a public audience. Many campus and community partners were involved, including experts from local museums and nature centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
