Bridging the Gap: Student Voices on Recruitment and Retention in Ecology
Abstract Students entering ecology and environmental science face a variety of challenges, including limited awareness of career paths, lack of mentorship, and difficulties connecting with peers and faculty. These challenges are often amplified for students from marginalized backgrounds, who may also encounter microaggressions, underrepresentation, and

A Refinement of Jensen’s and Minkowski’s Inequalities via Superquadratic Functions
We provide in this note a different refinement of Jensen’s inequality obtained via superquadratic functions. A refinement of Minkowski’s and Hölder’s inequalities is also established as an application of our refined Jensen’s inequality.
