Odontolabis Cuvera
''Odontolabis cuvera'', the golden stag beetle, is a beetle of the family Lucanidae, stag beetles.

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: [ˈmjænmɑː, ˈbɜːmə]. So the pronunciation of the last syllable of Myanmar as [mɑːr] or of Burma as [bɜːrmə] by some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad a, broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Beetles Of The World
''The Beetles of the World'' is a series of books devoted to Coleopterology. Sciences Nat published the 24 first volumes; the following volumes and the supplements were published by Hillside Books, Canterbury. The first book authored by Jacques Rigout was published in French ''Les Coléoptères du Monde'' in 1981 by Sciences Nat, and the book is a revision the genus ''Batocera''. The author printed the book himself, page by page. The 500 copy volume was professionally bound but was soon out of print. A second edition was printed by a professional in 1986. New authors came quickly to publish in the series. There were French specialists such as Gilbert Lachaume (Goliathini), Jean-Pierre Lacroix (Lucanidae), Patrick Bleuzen (Cerambycidae), Thierry Porion (Curculionidae), Roger-Paul Dechambre (Dynastidae), Marc Soula (Rutelinae) or Patrick Arnaud (Scarabaeidae), but also authorities from Belgium: Vincent Allard (Cetoniidae); Switzerland: Tiéry Lander (Buprestidae); Mexico: Miguel-A ...

:en:Texas A&M University
Texas A&M University (Texas A&M, A&M, or TAMU) is a public, land-grant, research university in College Station, Texas. It was founded in 1876 and became the flagship institution of the Texas A&M University System in 1948. Since 2021, Texas A&M has enrolled the largest student body in the United States, and is the only university in Texas to hold simultaneous designations as a land-, sea-, and space-grant institution. It is classified among "R1: Doctoral Universities – Very high research activity" and a member of the Association of American Universities. The university was the first public higher education institution in Texas; it opened for classes on October 4, 1876, as the Agricultural and Mechanical College of Texas (A.M.C.) under the provisions of the 1862 Morrill Land-Grant Act. In the following decades, the college grew in size and scope, expanding to its largest enrollment during WWII before its first significant stagnation in enrollment post-war. Enrollment g ...

Dorcus Rectus
''Dorcus rectus'', the little stag beetle, is a species of beetles in the family Lucanidae. It can be found in China(Liaoning), Korea, Japan, Taiwan and Russia. These beetles have a distinctive red shell that separates them from ''Dorcus curvidens''. Males of this species have been observed to have mandible trimorphism, a characteristic that has only been described in two species of Lucanidae—with the other one being Odontolabis cuvera—"and a small number of other invertebrates" as of 2017. The mandibles are used by males as weapons. References Lucaninae Beetles of Asia Insects of Japan Taxa named by Victor Motschulsky Beetles described in 1857 {{Lucanidae-stub ...

Trimorphism
{{Expert needed, biology, talk=Trimorphism#This line seems a misreading of Wallace, reason=Darwin might have misread Wallace, date=December 2018 In biology, trimorphism is the existence in certain plants and animals of three distinct forms, especially in connection with the reproductive organs. In trimorphic plants there are three forms, differing in the lengths of their Carpel, pistils and stamens, in size and color of their pollen grains, and in some other respects; and, as in each of the three forms there are two sets of stamens, the three forms possess altogether six sets of stamens and three kinds of pistils. These organs are so proportioned in length to each other that half the stamens in two of the forms stand on a level with the Stigma (botany), stigma of the third form. To obtain full fertility with these plants, it is necessary that the stigma of the one should be fertilized by pollen taken from the stamens of corresponding height in another form. Hence six unions are le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenotypes
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 cad ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
