Wilkiea Huegeliana
''Wilkiea huegeliana'' is a common small tree of rainforest in eastern Australia. Common names include common wilkiea, tetra beech, and veiny wilkiea. Originally described by French naturalist Louis René Tulasne, it was given its current name by Alphonse Pyramus de Candolle. The natural distribution is from Mount Dromedary (36° S) near Narooma in south eastern New South Wales to Maryborough (25° S) in south eastern Queensland. It has a preference for volcanic soils. The habitat of the common wilkiea is in the understorey of all forms or rainforest, except cool temperate forest subject to colder temperatures. Description ''Wilkiea huegeliana'' is a shrub or small tree achieving a height of , and a stem diameter of . The trunk is often crooked and irregular though not buttressed. The bark is smooth, brown or greyish, though can be somewhat scaly on larger plants. The leaves measure long, and wide, and are opposite on the stem. Elliptic or oblong in shape, they usually ...

Macquarie Pass National Park
Macquarie Pass National Park is a national park in New South Wales, Australia, 90 km southwest of Sydney. It is located around the pass of the same name, which is on the Illawarra Highway and part of the Illawarra escarpment. Macquarie Pass National Park was established in 1970 and protects a range of eucalypt forests and rainforest, including one of Australia's most southerly stands of subtropical rainforest. The pass was opened in 1898. It has been a major route into and out of the Illawarra coastal plain ever since. There is a major power line running east–west through the park. As well as a diverse array of birdlife the park has swamp wallabies and wombats. History The area was heavily logged for cedar in the first half of the 19th century. Facilities Picnic facilities are provided at two sites at the bottom of Macquarie Pass. Barbecues are provided at two other picnic areas. Walking tracks The Macquarie Rivulet track is two kilometres long and easy to medium gra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Laurales Of Australia
The Laurales are an order of flowering plants. They are magnoliids, related to the Magnoliales. The order includes about 2500-2800 species from 85-90 genera, which comprise seven families of trees and shrubs. Most of the species are tropical and subtropical, though a few genera reach the temperate zone. The best known species in this order are those of the Lauraceae (for example bay laurel, cinnamon, avocado, and ''Sassafras''), and the ornamental shrub ''Calycanthus'' of the Calycanthaceae. The earliest lauraceous fossils are from the early Cretaceous. It is possible that the ancient origin of this order is one of the reasons for its highly diverged morphology. Presently no single morphological property is known, which would unify all the members of Laurales. The presently accepted classification is based on molecular and genetic analysis. Classification The first botanist to think of the Laurales as a natural group was H. Hallier in 1905. He viewed them as being derived from ...

Uppsala University
Uppsala University ( sv, Uppsala universitet) is a public university, public research university in Uppsala, Sweden. Founded in 1477, it is the List of universities in Sweden, oldest university in Sweden and the Nordic countries still in operation. The university rose to significance during the rise of Swedish Empire, Sweden as a great power at the end of the 16th century and was then given a relative financial stability with a large donation from King Gustavus Adolphus of Sweden, Gustavus Adolphus in the early 17th century. Uppsala also has an important historical place in Swedish national culture, identity and for the Swedish establishment: in historiography, literature, politics, and music. Many aspects of Swedish academic culture in general, such as the white student cap, originated in Uppsala. It shares some peculiarities, such as the student nation system, with Lund University and the University of Helsinki. Uppsala belongs to the Coimbra Group of European universities a ...

Thrips
Thrips ( order Thysanoptera) are minute (mostly long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species. They fly only weakly and their feathery wings are unsuitable for conventional flight; instead, thrips exploit an unusual mechanism, clap and fling, to create lift using an unsteady circulation pattern with transient vortices near the wings. Many thrips species are pests of commercially important crops. A few species serve as vectors for over 20 viruses that cause plant disease, especially the Tospoviruses. Some species of thrips are beneficial as pollinators or as predators of other insects or mites. In the right conditions, such as in greenhouses, many species can exponentially increase in population size and form large swarms because of a lack of natural predators ...

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Understorey
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...
