Mammalogy
In zoology, mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as "mastology," "theriology," and "therology." The archive of number of mammals on earth is constantly growing, but is currently set at 6,495 different mammal species including recently extinct. There are 5,416 living mammals identified on earth and roughly 1,251 have been newly discovered since 2006. The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management and control. The approximate salary of a mammalogist varies from $20,000 to $60,000 a year, depending on their experience. Mammalogists are typically involved in activities such as conducting research, managing personnel, and writing proposals. Research purposes Mammalogists have stated that there are multiple reasons for the stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philip D
Philip, also Phillip, is a male given name, derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. It was also found during ancient Greek times with two Ps as Philippides and Philippos. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Lip, Pip, Pep or Peps. There are also feminine forms such as Philippine and Philippa. Antiquity Kings of Macedon * Philip I of Macedon * Philip II of Macedon, father of Alexander the Great * Philip III of Macedon, half-brother of Alexander the Great * Philip IV of Macedon * Philip V of Macedon New Testament * Philip the Apostle * Philip the Evangelist Others * Philippus of Croton (c. 6th ...

Phenotype
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and then again in his 1982 book '' The Extended Phenotype'' suggested that one can regard bird nests and other built structures such as ...

Deletion (genetics)
In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is left out during DNA replication. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome. Some chromosomes have fragile spots where breaks occur which result in the deletion of a part of chromosome. The breaks can be induced by heat, viruses, radiations, chemicals. When a chromosome breaks, a part of it is deleted or lost, the missing piece of chromosome is referred to as deletion or a deficiency. For synapsis to occur between a chromosome with a large intercalary deficiency and a normal complete homolog, the unpaired region of the normal homolog must loop out of the linear structure into a deletion or compensation loop. The smallest single base deletion mutations occur by a single base flipping in the template DNA, followed by template DNA strand slip ...

Insertion (genetics)
In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. Insertions can be anywhere in size from one base pair incorrectly inserted into a DNA sequence to a section of one chromosome inserted into another. The mechanism of the smallest single base insertion mutations is believed to be through base-pair separation between the template and primer strands followed by non-neighbor base stacking, which can occur locally within the DNA polymerase active site. On a chromosome level, an ''insertion'' refers to the insertion of a larger sequence into a chromosome. This can happen due to unequal crossover during meiosis. N region addition is the addition of non-coded nucleotides during recombination by terminal deoxynucleotidyl transferase. P nucleotide insertion is the insertion of palindromic sequences encoded by the ends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese language, Maltese and English language, English, and 66% of the current Maltese population is at least conversational in the Italian language, Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean Sea, Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Ancient Carthage, Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights Hospitaller, Knights of St. John, French, and British, amongst others.

Favignana
Favignana ( scn, Faugnana) is a ''comune'' including three islands (Favignana, Marettimo and Levanzo) of the Aegadian Islands, southern Italy. It is situated approximately west of the coast of Sicily, between Trapani and Marsala, the coastal area where the Stagnone Lagoon and the international airport of Trapani, are sited. Island The island of Favignana is famous for its tuna fisheries and is now a popular tourist destination with frequent hydrofoil connections to the mainland. History In ancient times Favignana was called ''Aegusa'', meaning "goat island" in Greek (Αιγούσα). The present name is derived from ''Favonio'', an Italian name for the foehn wind. The Phoenicians established an outpost on the island as a stopping point on their trans-Mediterranean trading routes until the defeat of the Carthaginian army during the First Punic War. On 10 March 241 BC, a major naval battle was fought a short distance offshore between the two powers. Two hundred Roman ships und ...

Palaeoloxodon
''Palaeoloxodon'' is an extinct genus of elephant. The genus originated in Africa during the Pliocene era, and expanded into Eurasia during the Pleistocene era. The genus contains some of the largest known species of elephants, over four metres tall at the shoulders, including the European straight-tusked elephant (''Palaeoloxodon antiquus''), and the southern Asian '' Palaeoloxodon namadicus'', the latter of which was possibly the largest known land mammal based on fragmentary remains, but this requires proper reexamination. In contrast, the genus also contains many species of dwarf elephants that evolved via insular dwarfism on islands in the Mediterranean, some only a metre in height, making them the smallest elephants known. The genus has a long and complex taxonomic history, and at various times, it has been considered to belong to '' Loxodonta'' or ''Elephas'', but today is usually considered a valid and separate genus in its own right. Taxonomy In 1924, circumscribed '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bark (botany)
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
