AUM math students present research at 2023 Joint Mathematics Meeting

Three Auburn University at Montgomery mathematics students recently presented research on mathematical population modeling to help provide solutions to habitat fragmentation at the 2023 Joint Mathematics Meeting.

The annual event was held January 4-7 in Boston, Massachusetts.

The student researchers collaborated with the research team of Jerome Goddard, AUM professor of mathematics, for their research project. Goddard’s team applies mathematical population modeling to help provide solutions to habitat fragmentation.

The process of habitat fragmentation occurs when a large portion of a habitat is transformed or destroyed, creating smaller areas or patches. For example, the construction of a road through a densely wooded area could create habitat fragmentation by disrupting the preferred environment of deer, raccoons, owls and other organisms residing there.

Goddard and the student researchers explored the role of the indirect effects of population harvesting on a competitive system where one species is harvested, and one is not.  The non-harvested species show increasing dispersal from habitat patches due to harvesting-induced disturbance, which the team describes as harvesting-dependent emigration.

The students’ undergraduate research project, which they began in January 2022, was sponsored by the AUM Department of Mathematics, an AUM Undergraduate Research and Creative Activity grant, and a National Science Foundation grant awarded to Goddard.

The annual Joint Mathematics Meetings is an annual conference held by the American Mathematical Society and the Mathematical Association of America, which brings together mathematicians from around the world to present their research, attend lectures and workshops, and network with other professionals in the field.
