Leafcutter Ant
Leafcutter ants, a non-generic name, are any of 47 species of leaf-chewing ants belonging to the two genera '' Atta'' and ''Acromyrmex''. These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico, and parts of the southern United States.. Leafcutter ants can carry twenty times their body weight and cut and process fresh vegetation (leaves, flowers, and grasses) to serve as the nutritional substrate for their fungal cultivates. ''Acromyrmex'' and ''Atta'' ants have much in common anatomically; however, the two can be identified by their external differences. ''Atta'' ants have three pairs of spines and a smooth exoskeleton on the upper surface of the thorax, while ''Acromyrmex'' ants have four pairs and a rough exoskeleton. The exoskeleton itself is covered in a thin layer of mineral coating, composed of rhombohedral crystals that are generated by the ants. Next to humans, leafcutter ants form some of the largest and most complex animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ant Colony
An ant colony is a population of a single ant species capable to maintain its complete lifecycle. Ant colonies are eusocial, communal, and efficiently organized and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution. The typical colony consists of one or more egg-laying queens, numerous sterile females (workers, soldiers) and, seasonally, many winged sexual males and females. In order to establish new colonies, ants undertake flights that occur at species-characteristic times of the day. Swarms of the winged sexuals (known as alates) depart the nest in search of other nests. The males die shortly thereafter, along with most of the females. A small percentage of the females survive to initiate new nests. Names The term "ant colony" refers to a population of workers, reproductive individuals, and brood that live together, cooperate, and treat one another non-aggressively ...

Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepiotaceae
The Agaricaceae are a family of basidiomycete fungi and include the genus ''Agaricus'', as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae. Taxonomy The family Agaricaceae was published by French botanist François Fulgis Chevallier in 1826. It is named after the type genus ''Agaricus'', originally circumscribed by Carl Linnaeus in his 1753 work ''Species Plantarum''. In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: ''Leucocoprineae'', ''Agariceae'', ''Lepioteae'', and ''Cystodermateae''. Genera once classified in the families Tulostomataceae, Battarreaceae, Lycoperdaceae, and Mycenastraceae have since been moved to the Agaricaceae based on molecular phylogenetics studies. According to a standard reference text, the Agaricaceae contains 85 genera and 1340 species. Description Agaricaceae species use a wide variety of ...

Ant–fungus Mutualism
The ant–fungus mutualism is a symbiosis seen between certain ant and fungal species, in which ants actively cultivate fungus much like humans farm crops as a food source. There is only evidence of two instances in which this form of agriculture evolved in ants resulting in a dependence on fungi for food. These instances were the attine ants and some ants that are part of the '' Megalomyrmex'' genus. In some species, the ants and fungi are dependent on each other for survival. This type of codependency is prevalent among herbivores who rely on plant material for nutrition. The microbes’ ability to convert the plant material into a food source accessible to their host makes them the ideal partner. The leafcutter ant is a well-known example of this symbiosis. Leafcutter ants species can be found in southern South America up to the United States. However, ants are not the only ground-dwelling arthropods which have developed symbioses with fungi. A mutualism with fungi is also no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atta Laevigata
''Atta laevigata'' ( Smith, 1858) is one of about a dozen species of leafcutter ants in the genus '' Atta'', found from Venezuela and south to Paraguay. This species is one of the largest leafcutter species, and can be recognized by the smooth and shining head of the largest workers in a colony. ''Atta laevigata'' is known in northern South America as ''hormiga culona'' (literally translated as "big-assed ant"), or as ''sikisapa'' in Peru, ''zompopo de mayo'' in Central America, ''bachaco culón'' in Venezuela, ''akango'' in Paraguay, and ''chicatana'' in Mexico. The colony sizes of these ants are made up of around 3.5 million individuals. Cuisine The ''hormiga culona'' has been eaten for hundreds of years, as a tradition inherited from pre-Colombian cultures as the Guanes. The ants are harvested for about nine weeks every year, at the time of the rainy season, which is when they make the nuptial flight; ''A. laevigata'' are used as traditional gifts in weddings.

Leaf Cutter Ants Arp
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs lig ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera ( ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the s ...

Atta Texana
The Texas leafcutter ant (''Atta texana'') is a species of fungus-farming ant in the subfamily Myrmicinae. It is found in Texas, Louisiana, and north-eastern Mexico. Other common names include town ant, parasol ant, fungus ant, cut ant, and night ant. It harvests leaves from over 200 plant species, and is considered a major pest of agricultural and ornamental plants, as it can defoliate a citrus tree in less than 24 hours. Every colony has several queens and up to 2 million workers. Nests are built in well-drained, sandy or loamy soil, and may reach a depth of , have 1000 entrance holes, and occupy . Description Workers measure in length, and are highly polymorphic. The back of the thorax has three pairs of spines. The ant has a narrow waist and is rusty brown in color. It should also be mentioned: Its closely-related cousin, ''Atta mexicana'' has colonies up to 8 Million, and the queen for ''A. mexicana'' is larger than the ''texana'' queen; however, it should also be mention ...

Pleometrosis
Pleometrosis is a behavior observed in social insects where colony formation is initiated by multiple queens primarily by the same species of insect. This type of behavior has been mainly studied in ants but also occurs in wasps, bees, and termites. This behavior is of significant interest to scientists particularly in ants and termites because nest formation often happens between queens that are unrelated, ruling out the argument of inclusive fitness as the driving force of pleometrosis. Whereas in other species such as wasps and bees co-founding queens are often related. The majority of species that engage in pleometrosis after the initial stages of colony formation will reduce their colonies number of queens down to one dominant queen and either kill or push out the supernumerary queens. However there are some cases where pleometrosis-formed colonies keep multiple queens for longer than the early stages of colony growth. Multiple queens can help to speed a colony through the earl ...
