Tetrix Ceperoi
''Tetrix ceperoi'', Cepero's groundhopper, is a member of the family Tetrigidae and is very similar to common grasshoppers. Grasshopper is defined as a "plant eating insect with long hind legs that are used for jumping and for producing a chirping sound". However, unlike the common grasshopper, the wings of ''T. ceperoi'' extend beyond its pronotum (the upper surface of the first segment of the thorax). The front wings have evolved throughout history to be stumps, and the back wings are very well developed. Thanks to the front wings only, ''T. ceperoi'' is capable of flying. Furthermore, ''T. ceperoi'' sports wide shoulders while covering its narrow abdomen beneath the pronotum. ''T. ceperoi'' are classified as Orthoptera, which describes crickets, grasshoppers, and locusts. Furthermore, these Orthoptera have incomplete metamorphosis, which also affects sexual dimorphism later. ''T. ceperoi'' reach an average length of about . ''T. ceperoi'' is a multi-coloured ground dweller with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignacio Bolívar
Ignacio Bolívar y Urrutia (9 November 1850, Madrid – 19 November 1944, Mexico City) was a Spanish naturalist and entomologist, and one of the founding fathers of Spanish entomology. He helped found the ''Real Sociedad Española de Historia Natural'' (Royal Spanish Natural History Society) in 1871, and was the author of several books and of over 1000 species. He also encouraged other naturalists to study entomology, José María de la Fuente being one example. In this field he wrote more than 300 books and monographs and described more than thousand new species and about 200 genera. After the Spanish Civil War he was exiled to Mexico Mexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatema ... when the nationalist government harshly repressed Republican militants and sympathisers. ...

Competition
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including Recognition (sociology), recognition: Competition occurs in nature, between living organisms which co-exist in the same natural environment, environment. Animals compete over water supplies, food, mates, and other resource (biology), biological resources. Humans usually Survival of the fittest, compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and celebrity, fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economy, market economies and business, often associated with business competition as companies a ...

Orthoptera Of Europe
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek ὀρθός ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuptial Gift
A nuptial gift is a nutritional gift given by one partner in some animals' sexual reproduction practices. Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include items ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bryum Caespitum
''Bryum'' is a genus of mosses in the family Bryaceae. It was considered the largest genus of mosses, in terms of the number of species (over 1000), until it was split into three separate genera in a 2005 publication. As of 2013, the classification of both ''Bryum'' and the family Bryaceae to which it belongs underwent significant changes based on DNA studies.Genus ''Bryum'', California Moss eFlora, Jepson eFlora for CA Vascular Plants, University Herbarium, University of California/ref> Description ''Bryum'' is a polyphyletic genus that has high morphological variation. Bryum species generally have shorter laminal cells with short, thick, and rounded stems. All ''Bryum'' species exhibit narrowed cells at the margins. Bryum species can be identified through patterns of asexual reproduction, coloration features of the stem and leaf base, and the strength of the leaf border. History The genus was described by Johann Hedwig in 1801, with the name being derived from the Greek word f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryum Argenteum
''Bryum argenteum'', the silvergreen bryum moss or silvery thread moss, is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope. Description The species is silvery-green or whitish-green colored when dry. This is because the broadly ovate shaped single leaflets in the tip do not form chlorophyll. The costa extends beyond the middle of the leaf. In damp, undisturbed locations, the branches may also form a more horizontal growth habit. The upper cells of the leaf surface are elongated rhomboid shaped. The capsule of the sporophyte is short cylindrical, appears broader at the base and is dark red to black colored. It has a high ability to tolerate drought and pollution of urban environments. ''B. argenteum'' is considered a desiccation tolerant species that can withstand total drying. While it is a common characteristic in mosses, ''B. argenteum'' was one of the first bryophytes experimentall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omocestus Viridulus
''Omocestus viridulus'', known in the British Isles as the common green grasshopper, is a Palearctic species of grasshopper in the subfamily Gomphocerinae. Morphology ''Omocestus viridulus'' are usually green all over, but some may have brown coloration on the sides. In Scandinavia, they are usually green or light brown. The males do not have any red coloring on the abdomen and possess a noticeably long ovipositor, characteristics that help distinguish it from the similar species '' O. rufipes'' and '' O. haemorrhoidalis''. The eyes of this species may be brown or yellow. The typical body length is . They possess a strongly darkened region of the hind wing. Distribution and habitat ''Omocestus viridulus'' typically lives in moderately wet regions around Europe except north of the Arctic Circle, and it is distributed widely over Britain. Its range extends east as far as Siberia and Mongolia. Their preferred habitat consists of areas with longer grass. Diet and life cycle This sp ...

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] |
