Developing general principles of host–microorganism interactions necessitates a robust
understanding of the eco-evolutionary processes that structure microbiota. Phylosymbiosis …

The small intestine of mammals and birds exhibits fascinating variation across taxa, body
size, and life history features such as locomotion and diet. In the intestine's brush border …

An often-stated ecomorphological assumption that has the status of 'textbook knowledge'is
that the dimensions of the digestive tract correlate with diet, where herbivores—consuming …

Molecular analyses of feces are widely used to study the feeding ecology of bats. However,
little is known about how detectability of prey DNA from bat feces is influenced by gut …

Conservation strategies centered around species habitat protection rely on species' dietary
information. One species at the focal point of conservation efforts is the herbivorous grouse …

Palms, like many plants, rely on frugivorous animals to disperse their seed. Large-scale
human-mediated dispersal for their production and amenity values has seen the introduction …

Background Due to its central role in animal nutrition, the gut microbiota is likely a relevant
factor shaping dietary niche shifts. We analysed both the impact and contribution of the gut …

Songbirds meet the extreme metabolic demands of migration by burning both stored fat and
protein. However, catabolizing these endogenous tissues for energy leads to organ atrophy …

Bats are unique among mammals in that they have evolved the capacity to fly. This has
generated strong selective pressure on the morphology and function of their digestive …

Birds are characterized by evolutionary specializations of both locomotion (eg, flapping
flight) and digestive system (toothless, crop, and gizzard), while the potential selection …
