A Faculty-Led, Community-Building Program That Enhances Student-Faculty Connections within Biology.

Connections between students and faculty on campus may influence students' sense of belonging, and a greater sense of belonging has a positive effect on student success. We developed a low-cost, faculty-led program of community-building events and implemented the program in the biology department at a small liberal-arts institution with the goal of improving students' sense of community. Student responses to surveys indicated that the majority of students felt connected to faculty and students in the department; however, Black or African American students initially felt a lower level of connection to faculty than did white students.

Developing a flexible learning activity on biodiversity and spatial scale concepts using open-access vegetation datasets from the National Ecological Observatory Network.

Biodiversity is a complex, yet essential, concept for undergraduate students in ecology and other natural sciences to grasp. As beginner scientists, students must learn to recognize, describe, and interpret patterns of biodiversity across various spatial scales and understand their relationships with ecological processes and human influences. It is also increasingly important for undergraduate programs in ecology and related disciplines to provide students with experiences working with large ecological datasets to develop students' data science skills and their ability to consider how ecological processes that operate at broader spatial scales (macroscale) affect local ecosystems.

Size dependency of post-disturbance recovery of multi-stemmed resprouting trees.

In frequently burned ecosystems, many plants persist by repeated resprouting from basal or belowground buds. This strategy requires that plants reach a balance between biomass loss and recovery, which depends on the shape of the relationship between pre- and post-fire size. Previous analyses of this relationship, however, have focused on the size of the largest stem, which ignores the importance of the multi-stem growth habit that is common in pyrogenic ecosystems.

Size-dependent enhancement of water relations during post-fire resprouting.

In resprouting species, fire-induced topkill causes a reduction in height and leaf area without a comparable reduction in the size of the root system, which should lead to an increase in the efficiency of water transport after fire. However, large plants undergo a greater relative reduction in size, compared with small plants, so we hypothesized that this enhancement in hydraulic efficiency would be greatest among large growth forms.
