Niche and neutral theories emphasize different processes contributing to the maintenance of species diversity3–5. Niche theory proposes that, in a community at equilibrium, each species must occupy a different niche, emphasizing the importance of environmental filtering or species interactions in ...

Although the details of neutral and niche theory may differ among studies, relatively few studies have examined their relative importance3. Beta diversity represents the compositional differentiation between species assemblages. Recent conceptual advances have been made using patterns of beta diversity to ...
Variation in community composition (beta-diversity) provides key insights into mechanisms of community assembly and biodiversity maintenance across local and regional scales1,2,3,4. Total beta-diversity arises from two components: species turnover (i.e., species replacement) and species nestedness (i...
"As society has shifted to prioritize individualism, we've seen increased name diversity," she explained. Generation Alpha: Why are we talking about them? Additionally, a growing appreciation for multiculturalism has led more parents to choose names tied to their ethnic heritage, reflecting a broad...
