One form of midden analysis examined the size of fecal pellets in pack rat middens. [17] The size of woodrat pellet is proportional to the size of the woodrat. By measuring the pellets, the approximate size of the woodrat was determined based on data from a study of field-trapped woodrats.
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] Starting in September, the woodrat will start to forage and store food in its midden for use and survival in the winter. [18]

Bushy-tailed woodrat on midden Paleo-ecologists have used a variety of techniques to analyze the plant and animal material in pack rat middens describe paleo-communities and infer paleo-climate. For example, the plant species present in middens, and the carbon isotope ratios on material in middens have been widely studied.[7] " all depends on ...

Initially, when their diachronic nature was less evident, they were viewed as the poor relation to the better studied pack rat middens. [37] [38] While pack rat middens are rich in identifiable macrofossils, which can be directly dated and provide high taxonomic resolution, hyrax middens are poor in macroremains. Those that are found are almost ...
