Herbivores which consume land plants may eat any or all of the fruit, leaves, sap, nectar, pollen, flowers, bark, cambium, underground storage organs like roots, tubers, and rhizomes, nuts, seeds, shoots, and other parts of plants; they frequently specialize in one or a few of these parts, though many herbivores also have quite diverse diets.

The marsh rice rat takes both vegetable and animal food, and is more carnivorous than most small rodents are; [168] dominant food items vary seasonally. Plants eaten include species of Spartina, Salicornia, Tripsacum, and Elymus, among others; it mainly eats seeds and succulent parts. [169]
Voles thrive on small plants yet, like shrews, they will eat dead animals and, like mice and rats, they can live on almost any nut or fruit. In addition, voles target plants more than most other small animals, making their presence evident. Voles readily girdle small trees and ground cover much like a porcupine. This girdling can easily kill ...
The short-tailed field vole is a small, dark brown rodent with a short tail, distinguishable from the closely related common vole (Microtus arvalis) by its darker, longer and shaggier hair and by its more densely haired ears. The head and body length varies between 8 and 13 centimetres (3.1 and 5.1 in) and the tail between 3 and 4 centimetres ...
Oryzomys is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (O. palustris) of the United States and O. couesi of Mexico and Central America—are widespread; the six others have more restricted distributions.
The bank vole is a small rodent resembling a mouse when young but developing a stouter body, a slightly rounder head with smaller ears and eyes and a shorter, hairy tail. The dorsal surface is reddish-brown, with a greyish undercoat and the flanks are grey with a reddish-brown sheen. The underparts are whitish-grey sometimes tinged with dull ...
Perognathinae is a subfamily of rodents consisting of two genera of pocket mice. Most species live in complex burrows within the deserts and grasslands of western North America , They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches [ 2 ] to their burrows.
In the 1970s, researchers removed kangaroo rats from an ecosystem in the Chihuahuan Desert, and for many years, no other small rodents moved in to fill the niche they left. In 1995, twenty years after the experimental removal, Bailey's pocket mouse moved into the area and filled the gap, almost completely replacing the missing kangaroo rats.
