Laboratory studies of rodents, such as mice and rats, frequently demonstrate positive thigmotaxis. Rodents often prefer to stay close to the walls of an open field or maze, a behavior known as wall-following or thigmotactic behavior. This tendency is utilized in behavioral experiments, such as the open field test, to assess anxiety-like ...
Sounds used by animals that fall within the scope of bioacoustics include a wide range of frequencies and media, and are often not "sound" in the narrow sense of the word (i.e. compression waves that propagate through air and are detectable by the human ear).
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

Hystricomorpha (from Greek ὕστριξ, hystrix 'porcupine' and Greek μορφή, morphē 'form') [2] is a term referring to families and orders of rodents which has had many definitions throughout its history. In the broadest sense, it refers to any rodent (except dipodoids) with a hystricomorphous zygomasseteric system.
Exclusion techniques refer to the act of sealing a home to prevent wildlife; such as, rodents (squirrels, rats, mice) and bats from entering it. [5] A common practice is to seal up areas that wildlife gain access to; such as an attic where animals might shelter to be free from the elements and predators.
The mechanism by which anechoic chambers minimize the reflection of sound waves impinging onto their walls is as follows: In the included figure, an incident sound wave I is about to impinge onto a wall of an anechoic chamber. This wall is composed of a series of wedges W with height H.
