The heights of plants preferred by herbivores can give indications of the local and regional herbivore density. [14] Compositional and structural changes in forest vegetation can have cascading effects on the entire ecosystem , including impacts on soil quality and stability, micro- and macro- invertebrates , small mammals, songbirds, and ...
The herd of goats eagerly wait for Greg Kalldin, the supervisor for the Goats on the Go Weatherford affiliate, to set up an electric fence to begin eating the brush at a new patch of land in ...
A male goat stands about 1 m (3.3 ft) at the shoulder to the waist and can weigh considerably more than the female (around 30% more in some cases). Male goats also have longer horns and longer beards than females. The head-and-body length can range from 120–179 cm (47–70 in), with a small tail adding 10–20 cm (3.9–7.9 in). [4] [5] [6]
Feral goats consist of many breeds of domestic goats, all of which stem from the wild goat (C. aegagrus). Although breeds can look different, they all share similar characteristics. Physically, both domestic and feral goats can be identified by their prominent straight horns (more prominent on male goats), rectangular pupils, and coarse hair.
Morton (1978) attributed this to the fact that leaves are heavy, slow to digest, and contain little energy relative to other foods. [2] The hoatzin is an example of a flighted, folivorous bird, but it is a weak flier, due to the well-developed foregut (used to digest its food) reducing the area available for flight muscles to attach.

Populus alba, commonly called silver poplar, [3] [4] silverleaf poplar, [3] [4] white poplar, [3] [4] or abele is a species of poplar, most closely related to the aspens (Populus sect. Populus). It is native to a region spanning from the Atlas Mountains of Africa, through most of South and Central Europe, into Central Asia; it has been ...
The leaves have relatively low nutritional value, and deer which feed exclusively on them have shown signs of malnutrition, cementing their status as a winter and emergency food for ungulates. Beavers and the white-footed vole are known to feed on salal leaves, as are domestic goats and sheep in some areas.
Populus fremontii, commonly known as Frémont's cottonwood, [1] is a cottonwood (and thus a poplar) native to riparian zones of the Southwestern United States and northern through central Mexico. [2] It is one of three species in Populus sect. Aigeiros. The tree was named after 19th-century American explorer and pathfinder John C. Frémont.
