Lake Fly
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironomus
''Chironomus'' is a genus of nonbiting midges in the subfamily Chironominae of the bloodworm family, Chironomidae, containing several cryptic species that can only be distinguished by experts based on the characteristics of their giant chromosomes. Description Adult ''Chironomus'' are midges with the pronotum widest in the middle and bearing a notch, the head usually bearing a pair of small tubercles above the antennal bases, the antennal flagellum of males having 11 segments, and the male genitalia has inferior volsella large and larger than superior volsella. They range from 5 to 13 mm in length. Larvae are red and usually have tubes on the side or bottom of the eighth abdominal segment. These features are not unique to ''Chironomus'', also being found in some related genera. Adult males can be distinguished from females by their feather-like antennae. Behaviour When at rest, adults often raise their front legs and vibrate them. This is the source of the genus name, which ...

WJW-TV
WJW (channel 8) is a television station in Cleveland, Ohio, United States, affiliated with the Fox network. Owned by Nexstar Media Group, WJW maintains studios on Dick Goddard Way (named for the station's late longtime weatherman—previously known as South Marginal Road) just northeast of downtown Cleveland near the shore of Lake Erie, and its transmitter is located in the Cleveland suburb of Parma, Ohio. History As WXEL The television station first signed on the air on December 19, 1949, as WXEL, originally broadcasting on VHF channel 9. It was founded by the Empire Coil Company, a wartime manufacturer of radio coils and transformers. The station was the third to sign on in Cleveland behind WNBK (then-channel 4, now WKYC channel 3), and WEWS-TV (channel 5), all of which signed on in a 13-month timeframe. In its early years, WXEL was a primary DuMont affiliate, and later became a secondary provider of ABC programs, sharing that affiliation with WEWS. WXEL also carried a n ...

Macrobenthos
Macrobenthos consists of the organisms that live at the bottom of a water columnJ.S. Link, C.A. Griswold, E.T. Methratta, J. Gunnard, Editors. 2006Documentation for the Energy Modeling and Analysis eXercise (EMAX). United States Department of Commerce, Northeast Fisheries Science Center. Reference Document 06-15 Chapter 8. and are visible to the naked eye. In some classification schemes, these organisms are larger than 1 mm; in another, the smallest dimension must be at least 0.5 mm. They include polychaete worms, pelecypods, anthozoans, echinoderms, sponges, ascidians, crustaceans. The marine macrobenthos community is a critical component and reliable indicator of the biotic integrity of marine ecosystems, especially the intertidal ecosystems. On the one hand, macrobenthos plays a vital role in maintaining ecosystem functions, such as material cycling in sediments and energy flow in food webs. On the other hand, macrobenthos is relatively sedentary and therefore r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromeliads
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ''Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (''Tillandsia usneoides''), and terrestrial species, such as the pineapple (''Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species that gath ...

Tree Throw
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
