Ficeae
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, b ...

Moraceae
The Moraceae — often called the mulberry family or fig family — are a family of flowering plants comprising about 38 genera and over 1100 species. Most are widespread in tropical and subtropical regions, less so in temperate climates; however, their distribution is cosmopolitan overall. The only synapomorphy within the Moraceae is presence of laticifers and milky sap in all parenchymatous tissues, but generally useful field characters include two carpels sometimes with one reduced, compound inconspicuous flowers, and compound fruits. The family includes well-known plants such as the fig, banyan, breadfruit, jackfruit, mulberry, and Osage orange. The 'flowers' of Moraceae are often pseudanthia (reduced inflorescences). Historical taxonomy Formerly included within the now defunct order Urticales, recent molecular studies have resulted in the family's placement within the Rosales in a clade called the urticalean rosids that also includes Ulmaceae, Celtidaceae, Cannabaceae, ...

Ficus Sycomorus
''Ficus sycomorus'', called the sycamore fig or the fig-mulberry (because the leaves resemble those of the mulberry), sycamore, or sycomore, is a fig species that has been cultivated since ancient times. The term ''sycamore'' spelled with an A has also been used for unrelated trees: the great maple, ''Acer pseudoplatanus'', or plane trees, ''Platanus''. The spelling "sycomore", with an O rather than an A as the second vowel is, if used, specific to ''Ficus sycomorus''. Distribution ''Ficus sycomorus'' is native to Africa south of the Sahel and north of the Tropic of Capricorn, also excluding the central-west rainforest areas. It also grows naturally in Lebanon; in the southern Arabian Peninsula; in Cyprus; in very localised areas in Madagascar; and in Israel, Palestine and Egypt. In its native habitat, the tree is usually found in rich soils along rivers and in mixed woodlands. Description ''Ficus sycomorus'' grows to 20 m tall and has a considerable spread, with a dense roun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Syconium
Syconium (plural ''syconia'') is the type of inflorescence borne by figs (genus ''Ficus''), formed by an enlarged, fleshy, hollow receptacle with multiple ovaries on the inside surface. In essence, it is really a fleshy stem with a number of flowers, so it is considered both a multiple and accessory fruit. Etymology The term ''syconium'' comes from the Ancient Greek word (''sykon''), meaning "fig". Morphology The syconium is an urn-shaped receptacle which contains between 50 and 7000 (depending on the species) highly simplified uniovulate flowers or florets on its inner surface. It is closed off from most organisms by the ostiole, fringed by scale-like bracts. Syconia can be monoecious or functionally dioecious: the former contain female flowers with variable style length and few male flowers, and produce seeds and pollen. The latter have male and female forms in different plants: seed figs contain female flowers with long styles and produce seeds; gall figs contain female ...

Aerial Root
Aerial roots are roots above the ground. They are almost always adventitious. They are found in diverse plant species, including epiphytes such as orchids (''Orchidaceae''), tropical coastal swamp trees such as mangroves, banyan figs ('' Ficus subg. Urostigma''), the warm-temperate rainforest rata (''Metrosideros robusta''), and pohutukawa trees of New Zealand (''Metrosideros excelsa''). Vines such as common ivy (''Hedera helix'') and poison ivy (''Toxicodendron radicans'') also have aerial roots. Types of aerial roots This plant organ that is found in so many diverse plant-families has different specializations that suit the plant-habitat. In general growth-form, they can be technically classed as '' negatively gravitropic'' (grows up and away from the ground) or ''positively gravitropic'' (grows down toward the ground). "Stranglers" (prop-root) Banyan trees are an example of a strangler fig that begins life as an epiphyte in the crown of another tree. Their roots grow ...

Agaonidae
The family Agaonidae is a group of pollinating and nonpollinating fig wasps. They spend their larval stage inside the fruits of figs. The pollinating wasps (Agaoninae, Kradibiinae, and Tetrapusiinae) are the mutualistic partners of the fig trees. The nonpollinating fig wasps are parasitic. Extinct forms from the Eocene and Miocene are nearly identical to modern forms, suggesting that the niche has been stable over geologic time. Taxonomy The family has changed several times since its taxonomic appearance after the work of Francis Walker in 1846 described from the wasp genus '' Agaon''. Previously the subfamilies Epichrysomallinae, Otitesellinae, Sycoecinae, Sycoryctinae, Sycophaginae, and Agaoninae were the subdivisions of the family. Recent works building strong molecular phylogenies with an extended sampling size have changed the composition of Agaonidae. First, the paraphyletic groups have been excluded (Epichrysomallinae, Otitesellinae, Sycoecinae, and Sycoryctinae) and ne ...

Pollination Syndrome
Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection. These traits include flower shape, size, colour, odour, reward type and amount, nectar composition, timing of flowering, etc. For example, tubular red flowers with copious nectar often attract birds; foul smelling flowers attract carrion flies or beetles, etc. The "classical" pollination syndromes were first studied in the 19th century by the Italian botanist Federico Delpino. Although they are useful in understanding of plant-pollinator interactions, sometimes the pollinator of a plant species cannot be accurately predicted from the pollination syndrome alone, and caution must be exerted in making assumptions. The naturalist Charles Darwin surmised that the flower of the orchid ''Angraecum sesquipeda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Ecological Niche
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantropical
A pantropical ("all tropics") distribution is one which covers Tropics, tropical regions of both hemispheres. Examples of species include caecilians, modern sirenians and the plant genera ''Acacia'' and ''Bacopa''. ''Neotropical'' is a zoogeographic term that covers a large part of the Americas, roughly from Mexico and the Caribbean southwards (including cold regions in southernmost South America). ''Palaeotropical'' refers to geographical occurrence. For a distribution to be palaeotropical a taxon must occur in tropical regions in the Old World. According to Armen Takhtajan, Takhtajan (1978), the following families have a pantropical distribution: Annonaceae, Hernandiaceae, Lauraceae, Piperaceae, Urticaceae, Dilleniaceae, Tetrameristaceae, Passifloraceae, Bombacaceae, Euphorbiaceae, Rhizophoraceae, Myrtaceae, Anacardiaceae, Sapindaceae, Malpighiaceae, Proteaceae, Bignoniaceae, Orchidaceae and Arecaceae.Takhtajan, A.
