Rodents are classified by a single pair of continuously growing incisors in both their upper and lower jaws; the length of their incisors are maintained by gnawing, which is how they eat. The diet of Rodents usually consists of seeds and plants, but some species do have more varied diets. Historically, Rodents have been keep as pets, used as laboratory animals, and treated as pests. Rodents accidentally introduced as invasive species to new ecosystems, most notably islands, have been seen to wreak havoc and cause extinction of naturally-occurring species. Rodents are found on all continents, except Antarctica, and are the only species, besides Bats and Sea Lions, to reach Australia without human introduction.
Rodents, a diverse group including rats, mice, and squirrels, are characterized by a pair of continuously growing incisors in both their upper and lower jaws, which they must constantly wear down by gnawing. These creatures have compact bodies with strong, agile limbs perfect for scurrying around. Many have bushy tails, which aid in balance, especially for tree-dwelling species. They communicate through a range of squeaks and chirps, often beyond human hearing range. With sharp senses of smell and hearing, they easily detect food and predators. Their whiskers, or vibrissae, provide tactile feedback, helping them navigate dark or tight spaces with finesse.
Humans have a complex relationship with rodents. Historically, species like rats and mice have been seen as pests, associated with disease and food spoilage, leading to widespread control measures. Yet, rodents like guinea pigs and hamsters are cherished pets. In pop culture, rodents range from the heroic (e.g., "Stuart Little") to the mischievous (e.g., "Tom and Jerry").
Conservation efforts often focus on endangered species, like the giant panda (a bamboo-eating rodent). Moreover, rodents are vital in scientific research, contributing significantly to medical advances. While some species are considered invasive, others play crucial roles in ecosystems, aiding seed dispersal and soil aeration.
A rodent’s diet depends on the species as well as habitat. For example, mice and rats are able to carry a flexible diet, and quickly adapt to the food available in their surroundings. Squirrels and beavers have more specific food requirements. Beavers exclusively eat plants such as grass and twigs. Rodents generally eat nuts, meat, fish, fruits, berries, and food scraps.
In order to keep rodents out of a garden remove any shelters they have such as brush piles and tall grass, remove food sources, control lawn grubs, and maintain the garden clean by keeping garbage and recycling bins clean. Also seal any holes, place fences, and place mesh tubes around any plants to prevent rodents from eating them.
There are about 2,050 species of rodents and these make up most the most diversified mammalian order. Rodents live all over the world except Antarctica. They can be found in almost every single country, as well as every type of habitat, including man-made environments. Rodents can be arboreal, semi-aquatic, or fossorial.
