Pheidole Loki
''Pheidole loki'' is a species of ant in the subfamily Myrmicinae. Description Majors for this possibly rare species could not be found and thus remain undescribed. ''Pheidole loki'' is most probably closely allied to ''P. jonas'' and '' P. vulcan'' and characterized by reduced sculpture and an intermediate amount of standing hairs, compared to these two species. Overall it resembles ''P. jonas'' more than ''P. vulcan'', at least in habitus, morphometric measurements, and promesonotum and postpetiole shape. The minor workers of ''P. jonas'', however, display a more strongly punctate sculpture, less abundant and less flexuous standing hairs, and on average slightly shorter scapes than ''P. loki'', the postpetiole on average as long as wide versus longer than wide in ''P. loki''. With all these easily visible differences between the minor workers of the two species, especially their very distinct pilosity patterns, the chance that ''P. loki'' is a morphologically aberrant consp ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pheidole Vulcan
''Pheidole vulcan'' (named after Vulcan, the Roman god of fire) is a species of ant in the subfamily Myrmicinae. Habitat and distribution ''Pheidole vulcan'' is known only from the slopes of the two volcanoes Mt. Karthala and La Grille, at elevations between 995 and 1125 m on Grande Comore and thus is possibly an endemic species of the island. The species has been found in rotten logs, sifted leaf litter, under tree bark and on the lower vegetation in montane rainforest. Description In its morphology this species is closely related to '' P. jonas'' and has been collected in sympatry. While all specimens of ''P. vulcan'' are orange in color, the specimens of ''P. jonas'' from Mt. Karthala are all dark. More important characters for separating the minor workers of the two species are the shape of the promesonotum in profile, which is less strongly angulate in ''P. jonas''; the amount of sculpture on the clypeus, which is smooth in ''P. jonas'' versus posteriorly punctate in ' ...

Habit (biology)
Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: *In zoology (particularly in ethology), habit usually refers to aspects of more or less predictable ''behaviour'', instinctive or otherwise, though it also has broader application. Habitus refers to the characteristic form or morphology of a species. *In botany, habit is the characteristic form in which a given species of plant grows (see plant habit).Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Behavior In zoology, ''habit'' (not to be confused with ''habitus'' as described below) usually refers to a specific behavior pattern, either adopted, learned, pathological, innate, or directly related to physiology. For example: * ...the atwas in the ''habit'' of springing upon the oor knockerin order to gain admission... * If these sensitive parrots are kep ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

Benara
Benara, or Mlima Bénara, is the highest peak of Grande-Terre, Mayotte, an overseas collectivity of France in the western Indian Ocean, with a height of . Description Benara forms part of the massif that dominates south-central Mayotte. The upper slopes of the mountain rise steeply to a triangular peak. Ridges extend 4 km west to the subordinate peaks of Tchaourembo (581 m), Ngouni Maboungani (510 m), and 4 km east to Trambatsini (297 m). The area down to an elevation of about 200 m, which is typically the upper limit of cultivation on the island, contains what is probably the second largest expanse of forest on Mayotte. It has been identified as an Important Bird Area (IBA) by BirdLife International because it supports populations of Comoro olive-pigeons, Comoro blue-pigeons, Mayotte drongos, Mayotte white-eyes and Mayotte sunbirds. It is also home to Robert Mertens's day geckos, island day geckos and Pasteur's day gecko Pasteur's day gecko (''P ...

Mayotte
Mayotte (; french: Mayotte, ; Shimaore: ''Maore'', ; Kibushi: ''Maori'', ), officially the Department of Mayotte (french: Département de Mayotte), is an overseas department and region and single territorial collectivity of France. It is located in the northern part of the Mozambique Channel in the Indian Ocean off the coast of Southeastern Africa, between Northwestern Madagascar and Northeastern Mozambique. Mayotte consists of a main island, Grande-Terre (or Maore), a smaller island, Petite-Terre (or Pamanzi), as well as several islets around these two. Mayotte is the most prosperous territory in the Mozambique Channel, making it a major destination for immigration. Mayotte's land area is and, with its 299,348 people according to January 2022 official estimates, is very densely populated at 800 inhabitants per km2 (2,073 per sq mi). The biggest city and prefecture is Mamoudzou on Grande-Terre. The Dzaoudzi–Pamandzi International Airport is located on the neighbouring is ...
