The bacterial composition of the pack rat’s gut microbiome is affected by what it eats, and by association, the geography of where the animal is from. However, while the bacterial composition of the pack rat microbiome is influenced by diet and geography, it is the animals’ genetics that has the most influential role on bacterial ...
When searching for food is dangerous or unproductive, animals often use food stores to supply all or part of their diet. This is a feasible strategy to avoid food shortage. It is the habit of collecting and storing both food and nonfood items that has earned the eastern woodrat is other common name of "pack-rat" or "trade rat". [17]
The Allegheny woodrat (Neotoma magister), is a species of "pack rat" in the genus Neotoma. Once believed to be a subspecies of the eastern woodrat ( Neotoma floridana ), extensive DNA analysis has proven it to be a distinct species.
The bushy-tailed woodrat prefers green vegetation (leaves, needles, shoots), but it will also consume twigs, fruits, nuts, seeds, mushrooms, and some animal matter. One study [ 7 ] in southeastern Idaho found grasses , cactus , vetch , sagebrush , and mustard plants in their diets, as well as a few arthropods .
Woodrats build extensive nests in trees, on the ground, and on bluffs with dense vegetation or rock cover. The conical shaped nests can be two to eight feet tall and are made of sticks, bark, and various plant matter. One nest can house successive generations of woodrats, with offspring adding to nests making them larger.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals.
Desert woodrats are relatively small for pack rats, measuring 28 to 39 cm (11 to 15 in) in length, including a 12 to 20 cm (4.7 to 7.9 in) tail. They weigh from 122 to 350 g (4.3 to 12.3 oz), with males being larger than females. Their coloring varies between individuals, and can be anything from pale gray to cinnamon to near-black.
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
