Plants partition the pollinator niche by depositing pollen on different parts of the pollinator body. by William A Arteaga-Chávez, Catherine H Graham, Esteban A Guevara, Boris A Tinoco

“…We evaluated plant niche partitioning at the species level based on all pollen found on a given species and at the body-part level by considering pollen loads on different hummingbird body parts, using the specialization metric (d') and beta diversity analysis. Niche partitioning of plants was higher when the different body parts of hummingbirds were considered than specialization at the species level. …”

Subspecific variation in gut microbiota of North American bison in a sympatric setting reveals differentially abundant taxa by Mikaella L. Grant, Renee M. Petri, Tristan M. Baecklund, Gregory A. Wilson, Christopher J. Kyle

“…Subspecific classification explained no significant differences in alpha diversity (p > 0.05) in the overall dataset, but has a potentially significant effect on beta diversity (p < 0.05, R2 = 0.04). Gut microbiota divergence between subspecies may be driven by differential abundance of specific taxa and associated functional pathways, likely influenced by dietary preferences, ancestral phenotypes, and historical ranges. …”
