Daphnia, a genus of small planktonic crustaceans, are 0.2–5 millimetres (0.01–0.20 in) in length. Daphniaare members of the orderCladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory (Wiktionary) swimming style resembles the movements of fleas. Daphnia live in various aquatic environments ranging from acidic swampsto freshwater lakes, ponds, streams and rivers.
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.

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material, a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees,[1] or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs.[citation needed]In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

Extremely fine print in an 18th century journal. The word best has been written over text that has been etched out. We imaged the fibers to find out what it use to say….. scandalous!
