Some organisms only graze (eat grass), some only browse (eat leaves), and others eat both. Coexistence of ecologically similar species is sustained by niche partitioning, a fundamental element of which is diet. Many of these definitions and revisions have occurred.

The niche has seemingly been defined and redefined almost as many times as it has been discussed.
These data support this idea but.
Understanding dietary specialization in herbivores has theoretical and practical implications in ecology, yet defining niche breadth consistently has been problematic. We assessed the dietary niche of two closely related carnivores, known to consume similar prey, across multiple regions spanning a broad geographic scale. Provides a simple explanation of dietary niche partitioning: It's a specialized area of focus within the broader field of nutrition.
Overlapping of resource requirements between. Niche breadth usually refers to the diversity of resources used or environments tolerated by an individual, population, species, or clade. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth forms but are. In the fall, partitioning breaks down to some degree, likely because food is so abundantly available, and both species.
A dietary niche isn't simply a single diet plan;
Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth forms but are. An animal’s dietary niche—the types and relative amounts of foods that it eats—is a key determinant of its interactions with and effects on other species. More than just a diet. Systems with regular pulses of resources act as a natural experiment to investigate the factors that influence the dietary niches of consumers.
Dietary niche partitioning appears to be seasonal;
