The observation that subjects from the same species clustered together and distinctly from other species with distinct microbiomes, suggests that while diet may play a role, species-specific factors are also important.
Although other animals such as seahorses take on reversed gender roles, species in the new genus are the first to be found with swapped genital structures.
Similar phenomena have already been described for "typical" sex-role species.
It is probable that carbohydrate storage plays an important role in species coexistence in species-rich meadows, a subject that deserves further study.
The test focused on students' understanding of the role of species in the ecosystem, interdependence among the species, the food chain, waste and respiration cycles, and how a change in one species affected the others.

She started in television, but got a small role in Species (1995) and then another in A Thousand Acres (1997).
Those studying natural ecosystems also welcomed the new work, saying it closely paralleled findings for the role of species diversity in reducing the incidence of disease in the wild.
This interaction also plays a role in species coexistence.
Meteorological factors (wind, rainfall, surface irradiance) had a significant role in species selection.
