Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamilton Ecological District
Hamilton Ecological District is part of the Waikato Ecological Region in New Zealand's North Island. It occupies the Hamilton basin and surrounding foothills, and has been heavily modified with less than two percent of its indigenous vegetation remaining. This location has been studied significantly including the process of restoration ecology. C. Michael Hogan has classified the undisturbed portions of the woodland area as a beech and podocarp forest with associate understory ferns being '' Icarus filiformis'', ''Asplenium flaccidum'', ''Doodia media'', '' Hymenophyllum demissum'', '' Zealandia pustulata'' and ''Dendroconche scandens ''Dendroconche scandens'', synonym ''Microsorum scandens'', commonly called fragrant fern, is a species of fern within the family Polypodiaceae.

Understory
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 ...

Blechnum Discolor
''Lomaria discolor'', synonym ''Blechnum discolor'', commonly called crown fern (Māori: piupiu), is a species of fern in the family Blechnaceae. This species is endemic to New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count .... As noted by C. Michael Hogan, this species is found in a number of forest communities in diverse locations within New Zealand, and is sometimes a dominant understory component. Spores are produced on specialised fronds. These are more erect, with a dark and shrivelled look.Andrew Crowe (1994). ''Which Native Fern?'', p. 39. Auckland: Viking. . References * C.

Rimu
''Dacrydium cupressinum'', commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps. The Māori name ''rimu'' comes from the Polynesian term ''limu'' which the tree's foliage were reminded of, ultimately from Proto-Austronesian *''limut'' meaning "moss". The former name "red pine" has fallen out of common use. Distribution Rimu grows throughout New Zealand, in the North Island, South Island and Stewart Island/Rakiura. This species is common in lowland and montane forest. Although the largest concentration of trees is now found on the West Coast of the South Island, the biggest trees tend to be in mixed podocarp forest near Taupō (e.g., Pureora, Waihaha, and Whirinaki Forests). A typical North Island habitat is in the Hamilton Ecological District, where '' Fuscospora truncata'' and rimu form the overstory. Associate ferns on the forest floor are ''Blechnum discolor'', ''B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothofagus
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clonal rep ...

Asteliaceae
Asteliaceae is a family of flowering plants, placed in the order Asparagales of the monocots. The family has only recently been recognized by taxonomists. The APG III system of 2009 (unchanged from the 1998 and 2003 versions) does recognize this family. The family includes three genera with about 38 species, occurring in the Southern Hemisphere. It is bird/insect pollinated and its conservation status as of 2017 is not threatened. Description A large variation in morphology is seen within this family. Roots The main cell type of the vascular tissue system present in roots are tracheids. Roots are the only plant organs to have vessel elements and this is seen commonly in Monocots. The habitat of a monocot will determine different xylem characteristics. The habitat of Asteliaceae gives rise to the variation seen in the xylem. These tracheary elements have pores in their walls from fragments of the pit membrane. The vessels that are present within Asteliaceae have very primitive ...
