Dietary DNA metabarcoding reveals a trophic niche partitioning among sympatric Iberian sandgrouses and bustards

The study of trophic niche partitioning is of great importance for understanding community structure and species coexistence, particularly if these are threatened. Here DNA metabarcoding was used to assess the diet of four threatened steppe bird species (two bustards and two sandgrouses), with the a...

Here DNA metabarcoding was used to assess the diet of four threatened steppe bird species (two bustards and two sandgrouses), with the aim of better understanding their dietary requirements, trophic interactions, and potential threats. The results showed seasonal and interspecific differences in their plant diet, with greater importance of cultivated plants during autumn and winter (around 50 % of their diet) than spring. Plants of the genus Convolvulus and of the family Brassicaceae were frequently consumed by all species. In spring, poppies (Papaver spp.) were a considerable part of their diet, and could be used as a source of carotenoids or for their anti-parasitic properties. Furthermore, results evidenced a trophic niche partitioning among species, with a marked segregation between bustard species and, to a lesser extent, between sandgrouse species. Diet similarity was generally higher between species from different orders that occur in mixed-species flocks (bustard - sandgrouse) than between species of the same order. This partitioning was probably related to a stratification in habitat use rather than to specialisation and might prevent competition to some extent. However, the homogenization of trophic resources resulting from agricultural intensification could pose an important threat, particularly during autumn, when weeds are scarcer and the most abundant trophic resource are sown seeds, which are often treated with pesticides.This research was mainly funded by the project REGRESSEDS (CGL2016-75278-R funded by MINECO, Spain).
