View striatus Acromyrmex leaf-cutting ants found in Neotropica.

He is a member of subfamily Myrmicinae, in the Attini tribe. As attine, Acromyrmex striatus forages for vegetation that will be applied to the fungal garden typical of all leaf-cutting species. The fungus feeds on the larvae of mycophagous and Queens, while the workers feed mainly on juice cut plants, and very little in mutualistically fungus making them, respectively, phytophagous and mycophagous. The presence of leaf-cutting ants so common in Neotropica that they are the main herbivores of these places.,

A. striatus is a polymorphic species, there are a few different sizes of workers, with the largest being 6.5 mm in length. This is done to separate different tasks, so they can be performed efficiently.


1. Distribution. (Распределение)

A. striatus is most common in the southern States of Santa Catarina and Rio Grande do Sul in Brazil, and also countries of Argentina, Uruguay and Paraguay. At least in Argentina, it prefers nesting sites in the arid and semi-arid regions, where the sun shines all year round.


2. Foraging. (Фуражировка)

A. striatus is an opportunistic forager, collecting material from all available sources. These ants can cut directly from plants, they can collect materials that have already fallen, or they can even collect feces and the bodies of other arthropods. In fact, the researchers found that at least 53 species of plants collected by A. striatus, from 23 families, most of them are Compositae, cereals and vegetable. However, from the point of view of the feeding area A. striatus generally keep to grass and shrubs., Foraging is carried out only in days with temperature above 20 °C. This means that in more temperate climates, feeding is limited to a few hours a day and only in summer. It is well documented that A. striatus shows a "resource-strategy", which assumes that workers will choose the food away from the nest to avoid excessive exploitation of resources closer to home. This will lead to target resources, having the opportunity to grow, before you reassemble. It has been suggested that the driving force of this behavior is that ants associated with obtaining high quality materials. It seems that A. striatus is in the provision of its mutualistically fungus with a reliable and predictable supply of power. This can be proven in a single study suggests that ant uses the same amount of many kinds of plants throughout the year.

Farmers may find themselves competing with A. striatus if the vegetation present in the area intended for human consumption.Feeding practices can be prevented in various ways, but in terms of control over nature, it seems that the ant species blandus not leaf-cutting species A. striatus deterred from feeding on bushes, where it collects nectar.


3. Socket. (Гнездо)

Nests can be found mostly in the open where the sun can Shine on them regularly and directly. The land is cleared of workers around the hole.

In order to prevent the spread of fires in South America, cuttings were implemented. It is curious that A. striatus favor these areas. The nests are carefully managed in order to maintain a stable moisture conditions, moisture, temperature, carbon dioxide levels, and many other factors. When people dig up the ground, soil more porous, allowing for better gas exchange and water absorption, helping the mushroom gardens. Really, not only rides, but any anthropogenic change of the soil, including roadsides. These favorable conditions for A. striatus as a result competitive advantage over other types of ant and can lead to increased damage to plant material.


4. Mating flights. (Токовые полеты)

Many kinds of ants to disperse a large number of sexual individuals in the air at once, synchronized with other colonies of the same species. This increases the mixing of individuals from different colonies, and therefore inhibits genetic instability through inbreeding. While in A. striatus, several people are involved in mating flights, increasing the probability of mating with related individuals. In addition, the breeding period lasts for several months, not weeks. Sexual individuals are produced from October to January, with a small number of people going to the nest each day, while the sun shines. Consequently, polyandry, the behavior of multiple fathers contributing to their sperm plays an important role in maintaining genetic diversity. We see evidence of this theory in reality as there are more men than women on average in L. striatus mating flights.


5. Social hierarchy and genetics. (Социальной иерархии и генетики)

Acromyrmex is the most complex taxon of the family Formicidae. The difficulties in the reproductive caste of Queens and males account for it. Possible configurations of the reproductive caste in the ant colonies is, monogyny one Queen, several Queens of polygyny, monandry sperm goes to one man, polyandry, sperm supplied by several males, and reproduction of the worker. Colonies may be founded by haplometrosis or pleometrosis one Queen several Queens. Each of these examples, the influence of the genetic relationship of all members of the colony.

In most ant species, colony Foundation haplometric. The earth Queen after a nuptial flight, bite off their wings so they dont hinder it in the hole, and digs into the main chamber. After a while she must leave the chamber and look for food.

It was found that the configuration of the reproductive caste in A. striatus depends on the density of colonizing Queens. A Mature colony is very low, so in conditions where there is a lot of Mature colonies of A. striatus, or a few reproductive females, ladies have been met to start a new colony together, without respect to how they relate to each other. In these conditions, brood Rearing can occur quickly, all together Queens to dig and divide the main camera, and, as a rule, the same fungal garden. Queens do not leave any food, minimizing chances to be victims. Produced more workers and fungus gardens more. But it is observed in other species of Acromyrmex that in the end all the ladies, except one, fulfilled.


6. Seed dispersal. (Распространение семян)

Many kinds of ants are very important to plants as a way of spreading seeds. A. striatus is no exception. It was evident that leaf-cutting ants forage the fruit and seeds of various kinds. In addition, as they cut more fleshy parts of the fruits, fungi do not infect the seeds, increasing the probability of viable seedlings. Ants collecting fruits and seeds and return them to their nest might lose a few seeds on the way. Useful matter is fed to the fungus, while the inedible parts are removed immediately outside the colony. Therefore, abandoned anthills are an important place for the next generation of plants. A. striatus were recorded demonstrating this behavior for many plants, including fasciculates the pepper tree, a native of Argentina. A. Striatus accidentally transports seeds of plants that have attractive structures on their seeds that encourage the transport ant.

The distance of dispersal depends on the distance the ant has traveled, and it was evident that the seeds are carried only short distances, at least when this method is compared to the vertebrate or wind dispersal. Although studies show that the soil in which leaf-cutter ants build their nests are favorable for plant growth, there is some debate among scholars whether the collection of leaf-cutting ants increases the effective rate of germination occurs. However, seedlings exposed to the negative effects of shade, and the soil below the parent tree. A. striatus removes the seed and puts them in the nest where the solar conditions with favorable soil. Another advantage to be sent more ants to avoid natural predators.The ripe fruit containing the seeds fall under the tree, the vertebrates are often looking for in these areas. If ants are in there first, the seeds of escape of organisms, which actually is a seed.
