Lick Run (Roaring Creek Tributary)
Lick Run is a small tributary of Roaring Creek in Columbia County, Pennsylvania, in the United States. It is approximately long. It is entirely in Locust Township. Its watershed has an area of 5.97 square miles. It is designated as a coldwater fishery and Class A Wild Trout Waters. Brown trout inhabit it, as to 14 other fish species. Numerous species of macroinvertebrate also inhabit the stream. Course Lick Run starts in southern Locust Township north of a mountain. It flows northeast into central Locust Township and then turns north for a short distance. The stream then turns northeast, passing the community of Newlin, and then gradually turns north again. Shortly downstream, it enters Roaring Creek some distance southeast of Slabtown. Lick Run joins Roaring Creek upstream of its mouth. Hydrology, geography, and geology In a visual assessment on a scale of 0 to 28 (with a higher number indicating higher quality), Lick Run scored 16.5 at Poorhouse Road. At Mill Road, near it ...

Roaring Creek (Pennsylvania)
Roaring Creek is a tributary of the Susquehanna River in Columbia County and Montour County, in Pennsylvania, in the United States. It is slightly more than long and flows through Roaring Creek Township, Locust Township, Catawissa Township, Cleveland Township, and Franklin Township in Columbia County and Mayberry Township in Montour County. The watershed of the creek has an area of . It has three named tributaries: South Branch Roaring Creek, Lick Run, and Mill Creek. The creek is not considered to be impaired and is not affected by coal mining. However, its watershed has been impacted by human land use. Claystones, conglomerates, sandstones, siltstones, and shales all occur within the watershed. The creek flows through a gorge in its lower reaches, along the border between Columbia County and Montour County. Most of the watershed of Roaring Creek is in Columbia County, but small areas are in Montour County, Northumberland County, and Schuylkill County. More than 4 ...

Minnow
Minnow is the common name for a number of species of small freshwater fish, belonging to several genera of the families Cyprinidae and Leuciscidae. They are also known in Ireland as pinkeens. Smaller fish in the subfamily Leusciscidae are considered by anglers to be "true" minnows. Types of minnows Bluntnose minnow (''Pimephales notatus''): The bluntnose minnow is a primary bait fish for Northern America, and has a very high tolerance for variable water qualities, which helps its distribution throughout many regions. The snout of the bluntnose minnow overhangs the mouth, giving it the bluntnose. There is a dark lateral line which stretches from the opercle to the base of the tail, where a large black spot is located. The average size of the adult is approximately 5 cm (2 in). 'Pimephales'' Common shiner (''Notropis cornutus)'': These fish are one of the most common type of bait fish and are almost exclusively stream dwellers. The common shiner can be identified b ...

Perlidae
The Perlidae are a family of stoneflies, with more than 50 genera and 1,100 described species. The majority of the Perlidae are found in eastern North America, but they occur worldwide except for Antarctica and parts of Africa. Their lifecycles range between one and three years. They adults emerge in the summer; they are very active and known to be attracted to light sources. They are usually very sensitive to changes in environment. Perlidae are usually lotic and lentic erosional. They are found in cool, clear medium-sized to large streams and sometimes in larger, warm rivers that carry silt. They are crawlers and can move quickly. In still water, no water moves over their gills, so they move their bodies up and down to keep oxygen flowing over them. They are engulfer-predators. They consume all types of invertebrates Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), de ...

Baetidae
Baetidae is a family of mayfly, mayflies with about 1000 described species in 110 genera distributed worldwide. These are among the smallest of mayflies, adults rarely exceeding 10 mm in length excluding the two long slender tails and sometimes much smaller, and members of the family are often referred to as small mayflies or small minnow mayflies. Most species have long oval forewings with very few cross veins (see Comstock-Needham system) but the hindwings are usually very small or even absent. The males often have very large insect eye, eyes, shaped like turrets above the head (this is known as "turbinate condition"). Baetids breed in a wide range of waters from lakes and streams to ditches and even rain barrel, water butts. The nymph (biology), nymphs are strong swimmers and feed mainly on algae. The oldest members of the family date to the Late Cretaceous, with ''Myanmarella'' and ''Vetuformosa'' known from the Cenomanian aged Burmese amber, and ''Palaeocloeon'' from ...

Turbellaria
The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic. There are about 4,500 species, which range from to large freshwater forms more than long or terrestrial species like ''Bipalium kewense'' which can reach in length. All the larger forms are flat with ribbon-like or leaf-like shapes, since their lack of respiratory system, respiratory and circulatory system, circulatory systems means that they have to rely on diffusion for internal transport of metabolites. However, many of the smaller forms are round in cross section. Most are predators, and all live in water or in moist terrestrial environments. Most forms reproduce sexual reproduction, sexually and with few exceptions all are hermaphrodites, simultaneous hermaphrodites. The Acoelomorpha and the genus ''Xenoturbella'' were formerly included in the Turbellaria, but are no longer regarded as Platyhelminthes. All th ...

Oligochaeta
Oligochaeta () is a subclass of animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms (some of which are semiaquatic or fully aquatic), and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms ( Enchytraeidae), blackworms ( Lumbriculidae) and several interstitial marine worms. With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or "bristles" on their outer body surfaces, and lack parapodia, unlike polychaeta. Diversity Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than up to in the 'giant' species such as the giant Gippsland earthworm (''Megascolides australis'') and the Mekong worm (''Amynth ...

Nigronia
Nigronia is a genus of megalopterous insects (dark fishflies) in the family of Corydalidae The family Corydalidae contains the megalopterous insects known as dobsonflies and fishflies. Making up about one dozen genera,See references in Haaramo (2008) they occur primarily throughout the Northern Hemisphere, both temperate and tropical, .... The typical size of species in the Nigronia genus are 20-30 millimeters. Species There are 2 species in the genus Nigronia; '' Nigronia serricornis'' and '' Nigronia fasciata''. The main thing that distinguishes the two species is that ''Nigronia fasciata'' has continuous and large white areas on its wings, whereas ''Nigronia serricornis'' has white spots on its wings which are isolated, rather than large and continuous.

Peltoperlidae
The Peltoperlidae, also known as roach-like stoneflies or roachflies, are a family of stoneflies. The family Peltoperlidae comprises 11 genera and 46 known species. Species are semivoltine, meaning their lifecycles last 1 to 2 years. Adults of the family usually emerge in late spring or early summer, April through June. Larvae are flattened and brown in color, and they are roach-like in appearance because of the expanded thoracic plates covering the bases of their legs, heads, and abdomens. Tapering gills occur on the thorax at the bases of the legs. These tracheal gills are multifunctional and key to many biological processes. No dense tufts or branching gills are found on their thoraces or abdomens, unlike other Plecoptera families. The larvae also possess broad, chisel-like mandibles. Adults have two ocelli in addition to its two compound eyes. Male epiprocts are sclerotized and rod-like in shape, and both sexes lack cross-veins in the anal lobe of the forewings. Peltoper ...

Ephemerellidae
Ephemerellidae are known as the spiny crawler mayflies. They are a family of the order Ephemeroptera. There are eight genera consisting of a total 90 species (Merritt & Cummins). They are distributed throughout North America as well as the UK. Their habitat is lotic-erosional, they are found in all sizes of flowing streams on different types of substrates where there is reduced flow. They are even found on the shores of lakes and beaches where there is wave action present. They move by swimming and clinging, they are very well camouflaged. Most species have one generation per year. They are mostly collector-gatherers. If threatened by a predator, the larva will raise its three tails in a "scorpion posture" to appear larger. It will then project its tails in front and poke the enemy. Most species are sensitive to disturbance. In the UK, the most commonly recorded species is ''Seratella ignita''. The nymph of this animal is often distinguished from other Mayflies by the darker ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambaridae
The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 Species. Most of the species in the family are native the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus ''Cambaroides'' are the only found outside North America, as they are restricted to eastern Asia. A few species, including the invasive ''Procambarus clarkii'' and '' Faxonius rusticus'', have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct. A 2006 molecular study suggested that the family Cambaridae may be paraphyletic, with the family Astacidae Astacidae is a family of freshwater crayfish native to Europe and western North America. The family is made up of four extant (living) genera: The genera '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
