The walleye, also called the yellow pike or yellow pikeperch or yellow pickerel, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a color morph that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification.
Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar, aspen, and cottonwood.
Populus section Aigeiros is a section of three species in the genus Populus, the poplars. Like some other species in the genus Populus, they are commonly known as cottonwoods. The species are native to North America, Europe, and western Asia. In the past, as many as six species were recognized, but recent trends have been to accept just three species, treating the others as subspecies of P. deltoides.
Liriodendron tulipifera—known as the tulip tree, American tulip tree, tulipwood, tuliptree, tulip poplar, whitewood, fiddletree, lynn-tree, hickory-poplar, and yellow-poplar—is the North American representative of the two-species genus Liriodendron, and the tallest eastern hardwood. It is native to eastern North America from Southern Ontario and possibly southern Quebec to Illinois eastward to southwestern Massachusetts and Rhode Island, and south to central Florida and Louisiana. It can grow to more than 50 m (160 ft) in virgin cove forests of the Appalachian Mountains, often with no limbs until it reaches 25–30 m (80–100 ft) in height, making it a very valuable timber tree. The tallest individual at the present time (2021) is one called the Fork Ridge Tulip Tree at a secret location in the Great Smoky Mountains of North Carolina. Repeated measurements by laser and tape-drop have shown it to be 191 feet 10 inches (58.47 m) in height. This is the tallest known individual tree in eastern North America.
Populus nigra, the black poplar, is a species of cottonwood poplar, the type species of section Aigeiros of the genus Populus, native to Europe, southwest and central Asia, and northwest Africa.
Populus alba, commonly called silver poplar, silverleaf poplar, or white poplar, is a species of poplar, most closely related to the aspens. It is native to a region spanning from the Atlas Mountains of Africa, through most of South and Central Europe, into Central Asia; it has been introduced to many temperate, moist regions worldwide. It grows in moist sites, often by watersides, in regions with hot summers and cold to mild winters.
The blue walleye, also called the blue pike, was a unique color morph of walleye which was endemic to the Great Lakes of North America. Morphometric studies led biologists to classify the blue walleye as a separate species in 1926, although it was later downgraded to a subspecies. Listed as an endangered species by the United States in 1967, it was declared extinct in 1983.
Leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species.
Maiestas is a genus of insects in the family Cicadellidae, the vast majority of which were formerly placed in the genus Recilia.
Deltocephalinae is a subfamily of leafhoppers. Deltocephalinae is the largest subfamily in the family Cicadellidae and is divided into 40 tribes, comprising over 925 genera, and over 6,700 described species.
Penthimia nigra is a species of leafhoppers belonging to the family Cicadellidae subfamily Deltocephalinae.
Ledra aurita or the eared leafhopper is a species of bug in the family Cicadellidae. It is the only species of the subfamily Ledrinae that lives in Europe, including the British Isles.
Typhlocybinae is a subfamily of insects in the leafhopper family, Cicadellidae. This is currently the second largest leafhopper subfamily based on the number of described species, but researchers believe there are so many taxa yet undescribed that it is probably the largest subfamily. Approximately 6000 species have been described thus far.
Oncopsis flavicollis is a species of leafhoppers belonging to the family Cicadellidae subfamily Eurymelinae.
Japananus hyalinus, the Japanese maple leafhopper, is a species of leafhopper of the subfamily Deltocephalinae and tribe Opsiini. Believed to be native to eastern Asia, it has been carried with the trade in cultivated maples and is now widely found in Europe, North America and Australia.
Potamanthus idiocerus is a species of hacklegilled burrower mayfly in the family Potamanthidae.
Epeorus vitreus is a species of flatheaded mayfly in the family Heptageniidae. It is found in southeastern Canada and the eastern United States.
Idiocerini is a tribe of leafhoppers in the family Cicadellidae, formerly treated as a subfamily, but now included within the subfamily Eurymelinae, and containing over 60 genera.
Corybas vitreus is a species of orchid endemic to New Zealand, and first described in 2016 by Carlos Adolfo Lehnebach.
Anoscopus albifrons is a species of insect in the family Cicadellidae. It was first described by Carl Linnaeus in 1758, in the 10th Edition of his Systema Naturae. It is found throughout Europe, the Azores, and parts of the United States and Canada. It inhabits grassy areas and forbs.
