Amyema Preissii
''Amyema preissii'', commonly known as wireleaf mistletoe, is a species of mistletoe, an epiphytic, hemiparasitic plant of the family Loranthaceae. It is native to Australia where it has been recorded from all mainland states. The flowers are red and up to 26 mm long. The fruits are white or pink, globose and 8–10 mm in diameter. Its habitat is sclerophyll forest and woodland where it is often found on wattles. On Victoria's Bellarine Peninsula its hosts include coast wirilda, golden wattle and drooping sheoak. Its sticky seeds are eaten and dispersed by mistletoebirds. Description Amyema Preissii is the only mistletoe with slender, needle-shaped leaves and all-red flowers lacking velvety covering, in groups of three. This distinctive mistletoe has feathery foliage, composed of soft, needle-like leaves (with pointed, but not sharp, tips). Foliage is either open and loosely branched or dense and very closely branched, with individual plants often displaying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Mistletoebird
The mistletoebird (''Dicaeum hirundinaceum''), also known as the mistletoe flowerpecker, is a species of flowerpecker native to most of Australia (though absent from Tasmania and the driest desert areas) and also to the eastern Maluku Islands of Indonesia in the Arafura Sea between Australia and New Guinea. The mistletoebird eats mainly the berries of the parasitic mistletoe and is a vector for the spread of the mistletoe's seeds through its digestive system.del Hoyo, J. et al., eds. (2008). ''Handbook of the Birds of the World'' 13: 388. . Taxonomy and evolution The mistletoebird is one of 44 species of the flowerpecker family Dicaeidae. The flowerpeckers are considered to be nearest in avian evolutionary relationship to the sunbird family Nectariniidae. Both the flowerpeckers and sunbirds are thought to be early offshoots of the early passeroid radiation that occurred 20-30 million years ago. The sunbirds are found mainly in Africa and Asia and the flowerpeckers throughout Asi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amyema
''Amyema'' is a genus of semi- parasitic shrubs (mistletoes) which occur in Malesia and Australia. Etymology ''Amyema'' derives from the Greek: ''a'' (negative), and ''myeo'' (I initiate), referring to the genus being previously unrecognised.

Frugivore
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directl ...

Nectarivore
In zoology, a nectarivore is an animal which derives its energy and nutrient requirements from a diet consisting mainly or exclusively of the sugar-rich nectar produced by flowering plants. Nectar as a food source presents a number of benefits as well as challenges. It is essentially a solution of (as much as 80%) the simple sugars sucrose, glucose and fructose, which are easily ingested and digested, representing a rich and efficient source of nutrition. This solution is often diluted either by the plant that produces it or by rain falling on a flower and many nectarivores possess adaptations to effectively rid themselves of any excess water ingested this way. However, nectar is an incomplete source of nutrition. While it does contain proteins and amino acids, these are found in low quantities, and it is severely deficient in minerals and vitamins. Very few organisms consume nectar exclusively over their whole life cycle, either supplementing it with other sources, particularly ...

Casuarina
''Casuarina'' is a genus of 17 tree species in the family Casuarinaceae, native to Australia, the Indian subcontinent, southeast Asia, islands of the western Pacific Ocean, and eastern Africa. It was once treated as the sole genus in the family, but has since been split into four genera (see: Casuarinaceae).Flora of Australia''Casuarina''/ref> They are evergreen shrubs and trees growing to tall. The slender, green to grey-green twigs bearing minute scale-leaves in whorls of 5–20. The apetalous flowers are produced in small catkin-like inflorescences. Most species are dioecious, but a few are monoecious. The fruit is a woody, oval structure superficially resembling a conifer cone, made up of numerous carpels, each containing a single seed with a small wing. The generic name is derived from the Malay word for the cassowary, ''kasuari'', alluding to the similarities between the bird's feathers and the plant's foliage, though the tree is called ''ru'' in Modern Malay.

Haustorium
In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients. For example, in mistletoe or members of the broomrape family, the structure penetrates the host's tissue and draws nutrients from it. In mycology, it refers to the appendage or portion of a parasitic fungus (the hyphal tip), which performs a similar function. Microscopic haustoria penetrate the host plant's cell wall and siphon nutrients from the space between the cell wall and plasma membrane but do not penetrate the membrane itself. Larger (usually botanical, not fungal) haustoria do this at the tissue level. The etymology of the name corresponds to the Latin word ''haustor'' meaning ''the one who draws, drains or drinks'', and refers to the action performed by the outgrowth. In fungi Fungi in all major divisions form haustoria. Haustoria take several forms. Generally, on penetration, the fungus increases the surface ar ...
