Coelioxys Sodalis
''Coelioxys sodalis'' is a bee from the family Megachilidae, one of numerous kleptoparasitic bees in the tribe ''Megachilini''. Members of the genus ''Coelioxys'' exhibit kleptoparasitic behavior in that they lay their eggs in the nests of other bees, typically those of the related genus ''Megachile''. As this behavior is similar to that of cuckoos, such bees are referred to as cuckoo bees. These host-parasite relationships are complex Host insects of the brood parasite ''C. sodalis'' include '' Megachile melanophaea'', ''M. texana'', and '' M. rotundata''. Taxonomy and naming The species was originally described in the ''Transactions of the American Entomological Society'' by Ezra Townsend Cresson in 1878. Range and distribution ''Coelioxys sodalis'' are distributed across the northern portions of the North American continent from Alaska and British Columbia and Northwest Territory eastward across to Nova Scotia and the New England states, according to Mitchell.

Essig Museum Of Entomology
The Essig Museum of Entomology is a research museum dedicated to terrestrial arthropods, located at the University of California at Berkeley. It contains perhaps the world's largest collection of California insects and has been ranked among the top university-based collections in North America. The museum is open to the public twice per year ( Cal Day and Darwin Day). The museum's origins date back to the 1880s, with the university's earliest teaching collection. After entomologist Edward Oliver Essig joined the faculty in 1914, he began to expand its collections. The research collection, starting with 10,000-15,000 specimens, was formalized in 1939 as part of the California Insect Survey (Experiment Station Project 1205), and in 1972 was named the Essig Museum of Entomology. Historically, the museum's primary geographical emphasis has been on western North America, with a focus on surveying the insects of California. More recently that focus has broadened to the eastern Pacific Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of Canada
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein Sequences
Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells. Peptides can also be synthesized in the laboratory. Protein primary structures can be directly sequenced, or inferred from DNA sequences. Formation Biological Amino acids are polymerised via peptide bonds to form a long backbone, with the different amino acid side chains protruding along it. In biological systems, proteins are produced during translation by a cell's ribosomes. Some organisms can also make short peptides by non-ribosomal peptide synthesis, which often use amino acids other than the standard 20, and may be cyclised, modified and cross-linked. Chemical Peptides can be synthesised chemically via a range of laboratory methods. Chemical methods typically synth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nucleotide
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine. Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP) and uridine triphosphate (UTP)—throughout the cell for the many cellular func ...

Rubus
''Rubus'' is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with over 1,350 species. Raspberries, blackberries, and dewberries are common, widely distributed members of the genus. Most of these plants have woody stems with prickles like roses; spines, bristles, and gland-tipped hairs are also common in the genus. The ''Rubus'' fruit, sometimes called a bramble fruit, is an aggregate of drupelets. The term "cane fruit" or "cane berry" applies to any ''Rubus'' species or hybrid which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as loganberry, boysenberry, marionberry and tayberry. The stems of such plants are also referred to as canes. Description Most species in the genus are hermaphrodites, ''Rubus chamaemorus'' being an exception. ''Rubus'' species have a basic chromosome number of seven. Polyploidy from the diploid (14 chromosomes) to the tetradecaploid (98 ...

Rhodora
''Rhododendron canadense'', the rhodora or Canada rosebay, is a deciduous flowering shrub that is native to northeastern North America. Classification Today's botanists consider the rhodora to be a distant relative of the other North American members of its genus, but the difference in floral structure did lead 19th century taxonomists to assign the plant its own genus ''Rhodora''. Its closest relative is ''Rhododendron vaseyi'' from the Appalachian Mountains, which differs in having seven stamens. DNA sequencing shows that ''R. vaseyi'' is not related to ''R. canadense'', but more to '' R. albrechtii''. Description It reaches a mature height of 0.5–1.2 m (approximately 1–3 feet). In early spring, it produces pinkish-purple flowers in clusters of 2–6 together; each flower is 2–3 cm (approximately 1 inch) in diameter, with a five-lobed purple corolla. The flowers are unusual in comparison with other species of the genus ''Rhododendron'' found in northeastern Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
