Insects of the family Formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behavior. Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)

Assessing genetic structure with multiple classes of molecular markers: a case study involving the introduced fire ant Solenopsis invicta. (1/1059)

We used 30 genetic markers of 6 different classes to describe hierarchical genetic structure in introduced populations of the fire ant Solenopsis invicta. These included four classes of presumably neutral nuclear loci (allozymes, codominant random amplified polymorphic DNAs (RAPDs), microsatellites, and dominant RAPDs), a class comprising two linked protein-coding nuclear loci under selection, and a marker of the mitochondrial DNA (mtDNA). Patterns of structure revealed by F statistics and exact tests of differentiation were highly concordant among the four classes of neutral nuclear markers, although the microsatellites were the most effective markers for detecting structure. The results from the mtDNA complemented those from the neutral nuclear markers by revealing that strong limitations to female-mediated gene flow were the cause of the local structure registered by the nuclear markers. The pattern of structure inferred from the selected nuclear loci was markedly different from the patterns derived from the other sets of markers but was predictable on the basis of the presumed mode of selection acting on these loci. In general, the results for all six classes of markers can be explained by known features of the social and reproductive biology of fire ants. Thus, the results from these diverse sets of markers, combined with detailed natural history data, provide an unusually complete picture of how the fundamental evolutionary forces of gene flow, drift, and selection govern the distribution of genetic variation within and between fire ant populations.  (+info)

Calibration of vector navigation in desert ants. (2/1059)

Desert ants (Cataglyphis sp.) monitor their position relative to the nest using a form of dead reckoning [1] [2] [3] known as path integration (PI) [4]. They do this with a sun compass and an odometer to update an accumulator that records their current position [1]. Ants can use PI to return to the nest [2] [3]. Here, we report that desert ants, like honeybees [5] and hamsters [6], can also use PI to approach a previously visited food source. To navigate to a goal using only PI information, a forager must recall a previous state of the accumulator specifying the goal, and compare it with the accumulator's current state [4]. The comparison - essentially vector subtraction - gives the direction to the goal. This whole process, which we call vector navigation, was found to be calibrated at recognised sites, such as the nest and a familiar feeder, throughout the life of a forager. If a forager was trained around a one-way circuit in which the result of PI on the return route did not match the result on the outward route, calibration caused the ant's trajectories to be misdirected. We propose a model of vector navigation to suggest how calibration could produce such trajectories.  (+info)

Attachment forces of ants measured with a centrifuge: better 'wax-runners' have a poorer attachment to a smooth surface. (3/1059)

The symbiotic ant partners of glaucous Macaranga ant-plants show an exceptional capacity to run on the slippery epicuticular wax crystals covering the plant stem without any difficulty. We test the hypothesis that these specialised 'wax-runners' have a general, superior attachment capacity. We compared attachment on a smooth surface for 11 ant species with different wax-running capacities. The maximum force that could be withstood before an ant became detached was quantified using a centrifuge recorded by a high-speed video camera. This technique has the advantage of causing minimum disruption and allows measurements in very small animals. When strong centrifugal forces were applied, the ants showed a conspicuous 'freezing reflex' advantageous to attachment. Attachment forces differed strongly among the ant species investigated. This variation could not be explained by different surface area/weight ratios of smaller and larger ants. Within species, however, detachment force per body weight (F/W) scaled with the predicted value of W(-)(0.33), where W is body weight in newtons. Surprisingly, our results not only disprove the hypothesis that 'wax-runners' generally attach better but also provide evidence for the reverse effect. Superior 'wax-runners' (genera Technomyrmex and Crematogaster) did not cling better to smooth Perspex, but performed significantly worse than closely related congeners that are unable to climb up waxy stems. This suggests an inverse relationship between adaptations to run on wax and to attach to a smooth surface.  (+info)

Octopamine reverses the isolation-induced increase in trophallaxis in the carpenter ant Camponotus fellah. (4/1059)

Social deprivation is an unusual situation for ants that normally maintain continuous contact with their nestmates. When a worker was experimentally isolated for 5 days and then reunited with a nestmate, she engaged in prolonged trophallaxis. It is suggested that trophallaxis allows her to restore a social bond with her nestmates and to re-integrate into the colony, particularly via the exchange of colony-specific hydrocarbons. Octopamine reduced trophallaxis in these workers as well as hydrocarbon transfer between nestmates, but not hydrocarbon biosynthesis. Administration of serotonin to such 5-day-isolated ants had no effect on the percentage of trophallaxis. Administration of phentolamine alone, an octopamine antagonist, had no effect, but when co-administrated with octopamine it reduced the effect of octopamine alone and restored trophallaxis to control levels. Moreover, the observed effect of octopamine was not due to a non-specific effect on locomotor activity. Therefore, we hypothesise that octopamine mediates behaviour patterns linked to social bonding, such as trophallaxis. On the basis of an analogy with the role of norepinephrine in vertebrates, we suggest that the levels of octopamine in the brain of socially deprived ants may decrease, together with a concomitant increase in their urge to perform trophallaxis and to experience social contacts. Octopamine administration may reduce this social deprivation effect, and octopamine could therefore be regarded as being partly responsible for the social cohesion between nestmates in ant colonies.  (+info)

Electron paramagnetic resonance study of the migratory ant Pachycondyla marginata abdomens. (5/1059)

Electron paramagnetic resonance was used to investigate the magnetic material present in abdomens of Pachycondyla marginata ants. A g congruent with 4.3 resonance of high-spin ferric ions and a very narrow g congruent with 2 line are observed. Two principal resonance broad lines, one with g > 4.5 (LF) and the other in the region of g congruent with 2 (HF), were associated with the biomineralization process. The resonance field shift between these two lines, HF and LF, associated with magnetic nanoparticles indicates the presence of cluster structures containing on average three single units of magnetite-based nanoparticles. Analysis of the temperature dependence of the HF resonance linewidths supports the model picture of isolated magnetite nanostructures of approximately 13 nm in diameter with a magnetic energy of 544 K. These particles are shown to present a superparamagnetic behavior at room temperature. The use of these superparamagnetic particle properties for the magnetoreception process of the ants is suggested.  (+info)

Pinpointing food sources: olfactory and anemotactic orientation in desert ants, Cataglyphis fortis. (6/1059)

Desert ants, Cataglyphis fortis, search for a repeatedly visited food source by employing a combined olfactory and anemotactic orientation strategy (in addition to their visually based path-integration scheme). This behaviour was investigated by video-tracking consecutive foraging trips of individually marked ants under a variety of experimental conditions, including manipulations of the olfactory and wind-detecting systems of the ants. If the wind blows from a constant direction, ants familiar with the feeding site follow outbound paths that lead them into an area 0.5-2.5 m downwind of the feeding station. Here, the ants apparently pick up odour plumes emanating from the food source and follow these by steering an upwind course until they reach the feeder. If the food is removed, foragers usually concentrate their search movements within the area downwind of the feeding site. Only when the wind happens to subside or when tail-wind conditions prevail do the ants steer direct courses towards the food. Elimination of olfactory input by clipping the antennal flagella, or of wind perception by immobilising the bases of the antennae, altered the foraging behaviour of the ants in ways that supported these interpretations. Ants with clipped flagella were never observed to collect food items.  (+info)

Lateral optic flow does not influence distance estimation in the desert ant Cataglyphis fortis. (7/1059)

The present account answers the question of whether desert ants (Cataglyphis fortis) gauge the distance they have travelled by using self-induced lateral optic-flow parameters, as has been described for bees. The ants were trained to run to a distant food source within a channel whose walls were covered with black-and-white gratings. From the food source, they were transferred to test channels of double or half the training width, and the distance they travelled before searching for home and their walking speeds were recorded. Since the animals experience different motion parallax cues when walking in the broader or narrower channels, the optic-flow hypothesis predicted that the ants would walk faster and further in the broader channels, but more slowly and less far in the narrower channels. In contrast to this expectation, neither the walking speeds nor the searching distances depended on the width or height of the channels or on the pattern wavelengths. Even when ventral-field visual cues were excluded by covering the eyes with light-tight paint, the ants were not influenced by lateral optic flow-field cues. Hence, walking desert ants do not depend on self-induced visual flow-field cues in gauging the distance they have travelled, as do flying honeybees, but can measure locomotor distance exclusively by idiothetic means.  (+info)

Three energy variables predict ant abundance at a geographical scale. (8/1059)

Energy theory posits three processes that link local abundance of ectotherms to geographical gradients in temperature. A survey of 49 New World habitats found a two order of magnitude span in the abundance (nests m(-2)) of ground nesting ants (Formicidae). Abundance increased with net primary productivity (r2=0.55), a measure of the baseline supply of harvestable energy. Abundance further increased with mean temperature (r2=0.056), a constraint on foraging activity for this thermophilic taxon. Finally for a given mean temperature, ants were more abundant in seasonal sites with longer, colder winters (r2 = 0.082) that help ectotherm taxa sequester harvested energy in non-productive months. All three variables are currently changing on a global scale. All should be useful in predicting biotic responses to climate change.  (+info)

I believe you may have accidentally omitted the word "in" from your search. Based on that, I'm assuming you are looking for a medical definition related to the term "ants." However, ants are not typically associated with medical terminology. If you meant to ask about a specific condition or concept, please provide more context so I can give a more accurate response.

If you are indeed asking about ants in the insect sense, they belong to the family Formicidae and order Hymenoptera. Some species of ants may pose public health concerns due to their ability to contaminate food sources or cause structural damage. However, ants do not have a direct medical definition associated with human health.

Ant venoms are toxic secretions produced by various species of ants as a defense mechanism against predators and to incapacitate their prey. The composition of ant venoms varies among different species, but they typically contain a mixture of alkaloids, peptides, and proteins that can cause a range of symptoms in humans, from mild irritation and pain to severe allergic reactions.

The venom of some ant species, such as the fire ants (Solenopsis spp.), contains alkaloids that can cause painful pustules and itching, while the venom of other species, like the bulldog ants (Myrmecia spp.), contains proteins that can induce severe allergic reactions and even anaphylactic shock in sensitive individuals.

Understanding the composition and effects of ant venoms is important for developing effective treatments for ant stings and for studying their potential therapeutic applications, such as using ant venom components in pain management or as leads for new drug development.

'Homing behavior' is not a term typically used in medical definitions. However, it is commonly used to describe an animal's innate ability to return to its home territory or nest after traveling large distances. This behavior has been observed in various species including birds, insects, and mammals. It is not a medical condition or disease.

A desert climate, also known as a hot desert climate or a BWh climate in the Köppen climate classification system, is characterized by extremely low rainfall, typically less than 10 inches (250 mm) per year. This type of climate is found in the world's desert areas, such as the Sahara Desert in Africa, the Mojave Desert in North America, and the Simpson Desert in Australia.

In a desert climate, temperatures can vary greatly between day and night, as well as between summer and winter. During the day, temperatures can reach extremely high levels, often above 100°F (38°C), while at night, they can drop significantly, sometimes below freezing in the winter months.

Desert climates are caused by a combination of factors, including geographical location, topography, and large-scale weather patterns. They typically occur in regions that are located far from sources of moisture, such as bodies of water, and are situated in the interior of continents or on the leeward side of mountain ranges.

Living things in desert climates have adapted to the harsh conditions through various means, such as storing water, reducing evaporation, and limiting activity during the hottest parts of the day. Despite the challenging conditions, deserts support a diverse array of plant and animal life that has evolved to thrive in this unique environment.

'Nesting behavior' is not a term typically used in medical definitions. However, it can be described as a type of behavior often observed in pregnant women, particularly close to their due date, where they have an intense desire to clean and organize their living space in preparation for the arrival of their baby. This behavior is considered a normal part of pregnancy and is not usually regarded as a medical condition.

In some cases, healthcare providers may use the term 'nesting' to describe a symptom of certain mental health disorders such as Obsessive-Compulsive Disorder (OCD) or Mania, where an individual may experience an intense urge to clean and organize their environment, but it is often accompanied by other symptoms that interfere with daily functioning.

Therefore, the definition of 'nesting behavior' can vary depending on the context in which it is used.

Mitochondrial ADP/ATP translocases, also known as adenine nucleotide translocators (ANT), are a group of proteins located in the inner mitochondrial membrane that play a crucial role in cellular energy production. These translocases facilitate the exchange of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) across the mitochondrial membrane, which is essential for oxidative phosphorylation and thus, energy homeostasis in the cell.

In more detail, during oxidative phosphorylation, ATP is produced within the mitochondria as a result of the electron transport chain's activity. This ATP must be exported to the cytosol for use by the cell's various processes. Simultaneously, the mitochondria need a continuous supply of ADP to sustain the production of ATP. The mitochondrial ADP/ATP translocases facilitate this exchange, allowing for the import of ADP into the mitochondria and the export of ATP to the cytosol.

There are multiple isoforms of the ADP/ATP translocase in humans (ANT1, ANT2, ANT3, and ANT4), encoded by different genes, with varying tissue distributions and functions. Dysfunction of these translocases has been implicated in several pathological conditions, including neurodegenerative diseases, ischemia-reperfusion injury, and cancer.

In the context of medicine and biology, symbiosis is a type of close and long-term biological interaction between two different biological organisms. Generally, one organism, called the symbiont, lives inside or on another organism, called the host. This interaction can be mutually beneficial (mutualistic), harmful to the host organism (parasitic), or have no effect on either organism (commensal).

Examples of mutualistic symbiotic relationships in humans include the bacteria that live in our gut and help us digest food, as well as the algae that live inside corals and provide them with nutrients. Parasitic symbioses, on the other hand, involve organisms like viruses or parasitic worms that live inside a host and cause harm to it.

It's worth noting that while the term "symbiosis" is often used in popular culture to refer to any close relationship between two organisms, in scientific contexts it has a more specific meaning related to long-term biological interactions.

The Adenine Nucleotide Translocator 3 (ANT3) is a protein found in the inner mitochondrial membrane. It plays a crucial role in cellular energy metabolism by facilitating the exchange of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) across the mitochondrial membrane.

More specifically, ANT3 transports ATP from the mitochondrial matrix to the cytoplasm, where it can be used for various cellular processes, while simultaneously transporting ADP in the opposite direction. This exchange is essential for maintaining the balance of adenine nucleotides and ensuring the proper functioning of the energy-producing machinery within the mitochondria.

ANT3 has also been implicated in the regulation of apoptosis or programmed cell death, as it can interact with pro-apoptotic proteins to facilitate the release of cytochrome c from the mitochondria, leading to caspase activation and cell death. Dysregulation of ANT3 function has been linked to various pathological conditions, including neurodegenerative diseases and cancer.
