Psocoptera are an order of insects that are commonly known as booklice, barklice or barkflies.[1] They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipteroids.[2] Their name originates from the Greek word ψῶχος, psokhosmeaning gnawed or rubbed and πτερά, ptera meaning wings.[3] There are more than 5,500 species in 41 families in three suborders. Many of these species have only been described in recent years.[4]

Galls or cecidia are a kind of swelling growth on the external tissues of plants or animals. Plant galls are abnormal outgrowths[1] of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from fungi and bacteria, to insects and mites. Plant galls are often highly organized structures and because of this the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.

Hydra is a genus of small, fresh-water animals of the phylum Cnidaria and class Hydrozoa. They are native to the temperate and tropical regions.[2][3] Biologists are especially interested in Hydra because of their regenerative ability – they appear not to ageor die of old age.
A core sample is a cylindrical section of (usually) a naturally occurring substance. Most core samples are obtained by drilling with special drills into the substance, for example sediment or rock, with a hollow steel tube called a core drill. The hole made for the core sample is called the “core bowling”. A variety of core samplers exist to sample different media under different conditions. More continue to be invented on a regular basis. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired.
