Graduate student mentorship as a target for diversifying the biological sciences

Despite the importance of a diversity of backgrounds and perspectives in biological research, women, racial and ethnic minorities, and students from non-traditional academic backgrounds remain underrepresented in the composition of university faculty. Through a study on doctoral students at a research-intensive university, we pinpoint advising from faculty as a critical component of graduate student experiences and productivity. Graduate students from minority backgrounds reported lower levels of support from their advisors and research groups. However, working with an advisor from a similar demographic background substantially improved productivity and well-being of these students. Several other aspects of mentoring practices positively predicted student success and belonging, including frequent one-on-one meetings, empathetic and constructive feedback, and relationships with other peer or faculty mentors. Our study highlights the need to renovate graduate education with a focus on retention - not just recruitment - to best prepare students for success in scientific careers.

Within-host adaptation alters priority effects within the phyllosphere microbiome

To predict microbiome composition and function over time, it is essential to understand how evolution alters priority effects between resident and invading species. In an experimental evolution study on tomato plants, an early-colonizing bacterial species rapidly evolved to invade a new niche, altering its ecological interactions with other members of the plant microbiome, as well as its effect on the host. Prevailing models have assumed that adaptation primarily improves the efficiency of resident species within their existing niches, yet we conclude that host habitats can offer alternative evolutionary opportunities, complicating the application of existing theory to the community ecology of microbiomes.
