Myrmecophytes
Myrmecophytes (; literally "ant-plant") are plants that live in a Mutualism (biology), mutualistic association with a colony of ants. There are over 100 different genera of myrmecophytes. These plants possess structural adaptations in the form of Domatium, domatia where ants can shelter, and food bodies and extrafloral nectaries that provide ants with food. In exchange for these resources, ants aid the myrmecophyte in pollination, seed dispersal, gathering of essential nutrients, and defense. Domatia adapted specifically to ants may be called myrmecodomatia. Mutualism Myrmecophytes share a Mutualism (biology), mutualistic relationship with ants, benefiting both the plants and ants. This association may be either facultative or obligate. Obligate In obligate mutualisms, the organisms involved are interdependent; they cannot survive on their own. An example of this type of mutualism can be found in the plant genus ''Macaranga''. All species of this genus provide food for a ...

Myrmecodia
''Myrmecodia'' is a genus of Epiphyte, epiphytic plants, present in Indochina, Malesia, Papuasia, and Queensland, Australia. It is one of five ant-plant genera in the family Rubiaceae, the others being ''Anthorrhiza'', ''Hydnophytum'', ''Myrmephytum'', and ''Squamellaria''. Myrmecophytes, or ant plants, live in a Mutualism (biology), mutualistic association with a colony of ants. These plants possess structural adaptations that provide ants with food and/or shelter. ''Myrmecodia'' are also classified as epiphytes. The term ''epiphytic'' derives from the Greek ''epi-'' (meaning 'upon') and ''phyton'' (meaning 'plant'). Epiphytic plants are sometimes called "air plants" because they do not root in soil. An epiphyte is a plant that grows harmlessly upon another plant and derives its nutrition and water supply from the air and debris found in its immediate environment. Epiphytes are a non-parasitic type of plant and differ from parasitic organisms in that this type of plant only re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Domatium
A domatium (plural: domatia, from the Latin "domus", meaning home) is a tiny chamber that houses arthropods, produced by a plant. Ideally domatia differ from galls in that they are produced by the plant rather than being induced by their inhabitants, but the distinction is not sharp; the development of many types of domatia is influenced and promoted by the inhabitants. Most domatia are inhabited either by mites or ants, in what can be a mutualist relationship, but other arthropods such as thrips may take parasitic advantage of the protection offered by this structure. Domatia occupied by ants are called myrmecodomatia. An important class of myrmecodomatia comprise large, hollow spines of certain acacias such as '' Acacia sphaerocephala'', in which ants of the genera '' Pseudomyrmex'' and '' Tetraponera'' make their nests. Plants that provide myrmecodomatia are called myrmecophytes. The variety of the plants that provide myrmecodomatia, and the ranges of forms of such domatia ...

Leporella Fimbriata
''Leporella fimbriata'', commonly known as ''hare orchid'' or ''fringed hare orchid'', is the only species in the flowering plant genus ''Leporella'' in the orchid family, Orchidaceae and is endemic to the southern Australia mainland. It is related to orchids in the genus '' Caladenia'' but has an unusual labellum and does not have hairy leaves. Its pollination mechanism is also unusual. Description ''Leporella fimbriata'' is a terrestrial, perennial, deciduous, sympodial herb with a few inconspicuous, fine roots and an oval-shaped tuber lacking a protective sheath. The tuber produces two "droppers" which become the daughter tubers in the following year. Unlike those in some other orchids, the droppers are produced well away from the parent tuber at the end of long, root-like stolons. There are one or two egg-shaped to lance-shaped, glabrous leaves at the base of the stem. The leaves are often small when the orchid flowers, but increase in size to long and wide, turning blui ...

Crematogaster
''Crematogaster'' is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (insect anatomy), gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal (tree-dwelling). These ants are also known as acrobat ants. Cocktail ants acquire food largely through predation on other insects, such as wasps.Schatz, Bertrand, and Martine Hossaert-Mckey. "Interactions of the Ant Crematogaster Scutellaris with the Fig/fig Wasp Mutualism." Ecological Entomology 28.3 (2003): 359-68. Print. They use venom to stun their prey and a complex trail-laying process to lead comrades to food sources. Like most ants, ''Crematogaster'' species reproduce by partaking in nuptial flights, where the queen acquires the sperm used to fertilize every egg throughout her life. Predatory ...

Pseudomyrmex Ferruginea Ryan Somma
''Pseudomyrmex'' is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World. Distribution and habitat ''Pseudomyrmex'' is predominantly Neotropical in distribution, but a few species are known from the Nearctic region. Most species are generalist twig nesters, for instance, ''Pseudomyrmex pallidus'' may nest in the hollow stems of dead grasses, twigs of herbaceous plants, and in dead, woody twigs. However, the genus is best known for several species that are obligate mutualists with certain species of ''Acacia sensu lato, Acacia''. Other species have evolved obligate mutualism with other trees; for example ''Pseudomyrmex triplarinus'' is obligately dependent on any of a few trees in the genus ''Triplaris''.Larrea-Alcázar, D. M. and J. A. Simonetti. (2007)Why are there few seedlings beneath the myrmecophyte ''Triplaris americana''?. ''Acta Oecologica'' 32(1) 112–1 ...

Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Pearl Bodies
Pearl bodies are small (0.5 - 3.0 mm), lustrous, pearl-like food bodies produced from the epidermis of leaves, petioles and shoots of certain plants. They are rich in lipids, proteins and carbohydrates, and are sought after by various arthropods and ants, that carry out vigorous protection of the plant against herbivores, thus functioning as a biotic defence. They are globose or club-shaped on short peduncles, easily detached from the plant, and are food sources in the same sense as Beltian bodies, Müllerian bodies, Beccarian bodies, coccid secretions and nectaries. They occur in at least 19 plant families (1982) with tropical and subtropical distribution. Cells or tissues that offer food rewards to arthropods are commonplace in the plant world and are an important way of establishing symbiotic relationships. Ants collect these energy-rich bodies (27.8 kJ/g dry weight) and carry them into their nests. Removal of these bodies appears to stimulate the formation of new ones in ...

Ochroma
''Ochroma pyramidale'', commonly known as balsa, is a large, fast-growing tree native to the Americas. It is the sole member of the genus ''Ochroma'', and is classified in the subfamily Bombacoideae of the mallow family Malvaceae. The tree is famous for its wide usage in woodworking, due to its softness and its high strength compared to its low density. The name ''balsa'' is the Spanish word for "raft" and the Portuguese word for ferry. A deciduous angiosperm, ''Ochroma pyramidale'' can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight. Balsa trees grow extremely fast, often up to 27 metres in 10–15 years, and do not usually live beyond 30 to 40 years. In terms of volume (as opposed to height) they may be the fastest growing tree known; Streets mentions one individual which grew tall and diameter at breast height during a period of fifteen mo ...

Catalpa Speciosa
''Catalpa speciosa'', commonly known as the northern catalpa, hardy catalpa, western catalpa, cigar tree or catawba, is a species of ''Catalpa'' native to the midwestern United States. The Latin specific epithet ''speciosa'' means "showy". Description ''Catalpa speciosa'' is a medium-sized, deciduous tree growing to tall and wide. It has a trunk up to in diameter, with brown to gray flaky bark. The leaves are deciduous, opposite (or whorled), large, heart shaped, long and broad, pointed at the tip and softly hairy beneath. The leaves generally do not color in autumn before falling; instead, they either fall abruptly after the first hard freeze, or turn a slightly yellow-brown before dropping off. The catalpa tree is the last tree to grow leaves in the spring. The winter twigs of northern catalpa are like those of few other trees, having sunken leaf scars that resemble suction cups. Their whorled arrangement (three scars per node) around the twigs is another diagnostic. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cherry Petiole Glands
A cherry is the fruit of many plants of the genus ''Prunus'', and is a fleshy drupe (stone fruit). Commercial cherries are obtained from cultivars of several species, such as the sweet ''Prunus avium'' and the sour ''Prunus cerasus''. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus ''Prunus'', as in "ornamental cherry" or "cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although ''Prunus avium'' is often referred to specifically by the name "wild cherry" in the British Isles. Botany True cherries ''Prunus'' subg. ''Cerasus'' contains species that are typically called cherries. They are known as true cherries and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. ''P. serrula''; some species with short racemes, e.g. ...
