Linking Phylogeny and Morphology to Resource Assimilation Within Aquatic Assemblages.

Niche partitioning promotes species coexistence. Yet, it remains unclear how phylogeny and morphology influence the trophic niches of closely related aquatic species with shared feeding modes. Freshwater mussels (Family: Unionidae) are a group of filter-feeding bivalves that are ideal for investigating mechanisms of niche partitioning.

Evolutionary history drives aspects of stoichiometric niche variation and functional effects within a guild.

Functional traits are characteristics of an organism that represents how it interacts with its environment and can influence the structure and function of ecosystems. Ecological stoichiometry provides a framework to understand ecosystem structure and function by modeling the coupled flow of elements (e.g.
