Priority effects, where arrival order and initial relative abundance modulate local species interactions, can exert taxonomic, functional, evolutionary influences on ecological communities by driving them to alternative states. It remains unclear if these wide-ranging consequences of priority effects be explained systematically a common underlying factor. Here, we identify such factor in an empirical system. In series field laboratory studies, focus how pH affects nectar-colonizing microbes...

ABSTRACT Priority effects, where the order and timing of species arrival influence assembly ecological communities, have been observed in a variety taxa habitats. However, genetic molecular basis priority effects remains unclear, hindering better understanding when will be strong.

Microbiology conferences can be powerful places to build collaborations and exchange ideas, but for queer transgender (trans) scientists, they also become sources of alienation isolation. Many conference organizers would like create welcoming inclusive events feel ill-equipped make this vision a reality, historical lack representation trans folks in microbiology means we rarely occupy these key leadership roles ourselves. Looking more broadly, scientists are systematically marginalized...

As queer and trans scientists, we face varied systemic barriers to our professional success, resulting in relative absence from faculty ranks at many institutions. In this Perspective, call for a change hiring practices present concrete guidance make it more inclusive process.

Scientists and artists are both motivated by creativity curiosity, science art can be mutually reinforcing, supporting discovery innovation. This Community Page highlights resources for individuals, groups, institutions to advance science–art collaborations.

Abstract The biotechnology design (biodesign) enterprise is reshaping our relationship with nature and requires broad public engagement for innovative ethical development. However, current biodesign programs are often limited to formal education settings such as universities, community colleges high schools. To grow deeper networks amongst communities that excluded, we need new approaches learning spaces. These must expand the diversity of voices frame questions drive when, where, how...

Scientific meetings and conferences play a crucial role in knowledge dissemination, fostering collaborations, professional development, inspiring innovative research. However, their traditional structure organisation have remained largely unchanged, perpetuating barriers that continue to exclude scientists from under-represented groups. In response, the Microbiology Society has begun its journey address these longstanding challenges, redesigning create more inclusive culture welcoming...

Queer and transgender scientists face documented systemic challenges across the sciences, as a result have higher attrition rate than their peers. Recent calls for change within microbiology emphasized importance of addressing barriers to success retention queer trans microbiologists create more inclusive, equitable, just scientific establishment. Crucially, we note these come primarily from early career researchers; relatively few us passed through gauntlet faculty job search, this is key...
