Rough Draft EASTERN WOODRAT (NEOTOMA FLORIDANA) Eastern Woodrats are known for their foraging and caching habits. 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”. Woodrats will drop the object they are carrying for a more desirable one (Wilson). Eastern Woodrats eat about 5% of their body weight in dry mass each day. During the summer months, most feeding is done while foraging. Only small amounts of food are taken back to the den for daytime feeding (Wiley). Woodrats do not change significantly in weight from autumn to spring. Weight of individual woodrats is not correlated to the kilocalories in their caches (Horne). Starting in September, the woodrat will start to forage and store food in its midden for use and survival in the winter (Whitaker). Although cache does not serve as the sole source of winter diets, caches examined yielded as much as a bushel of plant material (Wilson). Woodrats have great adaptability in their feeding habits. They feed on almost any kind of plant material including leaves, roots and tubers, wood, bark, stems, and seeds (Guilliams). Although the Eastern Woodrats eat mostly green vegetation, they also eat various types of fruits, nuts, fungi, ferns, and seeds (Whitaker). Food preferences vary from population to population. What one population may favor, another may not use (Wiley). Variety of food cache depends on the availability of food sources within foraging ranges of individuals (Horne). Woodrat feeding and caching habits vary from one geographic area to another. In Texas, pecans are a major food source for the Eastern Woodrat. In Tennessee, mint and beechnuts were found to be the most cached item. In Pennsylvania, mushrooms were one of the top food items found in their middens (Wiley). Acorns, the nut of an oak tree, are a major food source for all Woodrat populations. Oak trees are found throughout the Woodrat’s habitat from Texas to New York. Acorns are considered a valuable caching item due to the acorn’s long shelf life (Wiley). Energy and perishability influence the woodrat’s diet and caching. The value of food when consumed should equal or exceed the cost of gathering and storage (Post, McDonald, Reichman). Food is chosen by dryness and degree of microbial infection. Woodrats tend to eat perishable food and cache less perishable foods. This strategy reduces the risk of stored foods being loss to spoilage. Woodrats are constantly coping with food stores decomposing by microbes. Woodrats seem to exhibit physiological adaptions, allowing them to comsume food inhabited by fungi. Fungi can increase nutritional value of some foods by making nutrients within food more accessible by breaking down complex carbohydrates into monosaccharides and disaccharides. If there is any nutritional value to fungi infected foods, caching rodents, such as the Woodrat, would definitely exploit those resources and benefits (Herrera). Although Woodrats are herbivores, evidence suggests that Woodrats will eat meat if given the opportunity. Snakes, salamanders, mice, and quail have all been found in stomachs of Woodrats (Williams). In addition to meat, researchers have found gnawed bones in caches and believe Woodrats use them to sharpen their teeth and for mineral nutrients. Only anectodal evidence exists concerning Woodrat carnivory(Nowak,Williams). Being an opportunist, The Woodrat will cache a carcass if given the chance. Drinking water is typically not needed. Woodrats get the water they need from dew, water containing plants such as succulents, and fruit. The Eastern Woodrat can survive during drought seasons on water obtained from metabolism of food (Wiley). Eastern Woodrats receive transmission of information regarding diet in a variety of ways from birth to juvenile. Woodrats start to get diet cues via their mother's milk. They also get cues from coming in contact with food particles that are stuck to the fur, and any fecal pellets in the den. After the young ween from their mother they learn other food cues from olfaction(sense of smell) and observation of other experienced woodrats. Evidence also indicates that dietary cues can be transmitted to offspring before birth(Post, McDonald, Reichman). Transmission cues can greatly reduce the costs of foraging, especially juvenile woodrats, who are particularly vulnerable to environmental stress. Woodrats are solitrary foragers. Juveniles that have left the nest, can no longer learn by observation and must rely strictly on diet cues given to them by their mother.
