Evolutionary ecologist works on 15-year international research collaboration with insight into the impact of density-dependence on populations

Ronald D. Bassar, an assistant professor in the Department of Biological Sciences, is part of a team of five researchers whose work, Population Regulation and Density-Dependent Demography in the Trinidadian Guppy, was published in the journal, The American Naturalist.

Nature featured a ‘NEWS AND VIEWS’ article, How population size shapes the evolution of guppy fish, highlighting the results of the research focusing on the role of density-dependent regulation of population size in the evolutionary processes.

“I am excited that years of dedicated research can help fill the gaps of research that was lacking in key areas in the scientific field,” said Bassar. “This data provides valuable information about the evolution of these fish that will help other researchers unlock future results."

A Road Not Taken: Exploring Alternate Realities to Explain AI

On Thursday, Feb. 22, you can learn more about one of the most popular topics discussed today, Artificial Intelligence (AI). Ash Abebe, chair of the Department of Mathematics and Statistics, will present “A Road Not Taken: Exploring Alternate Realities to Explain AI” at the John Emerald Distillery at 6:15 p.m.

His talk will share insight through the exploration of diverse models and hypothetical scenarios in AI.

"As a long-time COSAM faculty member, I'm excited to have an opportunity to discuss the topics of AI and machine learning at the Science Café,” said Abebe. “These technologies are increasingly important yet challenging to explain. I look forward to discussing how exploring a range of equally valid models for a given dataset and conducting what-if scenario explorations can offer clearer insights."
