Rhabdothamnus Solandri Kz1
''Rhabdothamnus solandri'' is a small shrub of the family Gesneriaceae endemic to New Zealand. It is the only plant of the genus ''Rhabdothamnus'', and the only member of Gesneriaceae native to New Zealand. Its common names are New Zealand gloxinia and, in the Māori language, , , and . The species is found throughout the North Island, less commonly in the southern part of the island, and its offshore islands, in a variety of locations such as forests, near streams, or on banks. It grows as a shrub up to 2 metres tall. It has distinctive trumpet-shaped flowers that are modest-sized at 2–2.5, and up to 4, centimetres long. The flowers are usually orange, but sometimes brick-red, yellow, purple or pink, and are longitudinally striped by 12–14, even up to 20, red or dark orange veins.

Allan Cunningham (botanist)
Allan Cunningham (13 July 1791 – 27 June 1839) was an English botany, botanist and List of explorers, explorer, primarily known for his expeditions into uncolonised areas of eastern Australia to collect plants and report on the suitability of the land for grazing purposes. Early life Cunningham was born in Wimbledon, London, England, the son of Allan Cunningham (head gardener at Wimbledon Park House), who came from Renfrewshire, Scotland, and his English wife Sarah (née Juson/Jewson née Dicken). Allan Cunningham was educated at a Putney private school, Reverend John Adams (educational writer), John Adams Academy and then went into a solicitor's office (a Lincoln's Inn Conveyancer). He afterwards obtained a position with William Townsend Aiton superintendent of Royal Botanic Gardens, Kew, Kew Gardens, and this brought him in touch with Robert Brown (Scottish botanist from Montrose), Robert Brown and Joseph Banks. Brazil On Banks' recommendation, Cunningham went to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar Robbing
Nectar robbing is a foraging behavior used by some organisms that feed on floral nectar, carried out by feeding from holes bitten in flowers, rather than by entering through the flowers' natural openings. Nectar robbers usually feed in this way, avoiding contact with the floral reproductive structures, and therefore do not facilitate plant reproduction via pollination. Because many species that act as pollinators also act as nectar robbers, nectar robbing is considered to be a form of exploitation of plant-pollinator mutualism. While there is variation in the dependency on nectar for robber species, most species rob facultatively (that is, to supplement their diets, rather than as an absolute necessity). The terms nectar theft and floral larceny are also been used in literature. Nectar robbers vary greatly in species diversity and include species of carpenter bees, bumblebees, stingless '' Trigona'' bees, solitary bees, wasps, ants, hummingbirds, and some passerine birds, inclu ...

Endemic Flora Of New Zealand
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Monotypic Gesneriaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Gesnerioideae
The Gesnerioideae are a subfamily of plants in the family Gesneriaceae: based on the type genus ''Gesneria''. Although genera typically originate in the New World, some species have become widely distributed as ornamental plants. Description Gesnerioideae is one of two main subfamilies in the Gesneriaceae, the other being Didymocarpoideae. (The third subfamily, Sanangoideae, contains only the genus ''Sanango''.) Gesnerioideae seedlings have normal cotyledons of the same size and shape (isocotylous), whereas the cotyledons of Didymocarpoideae are usually, but not always, eventually different in size and shape (anisocotylous). Gesnerioideae flowers usually have four fertile stamens, rarely two or five. In other respects, Gesnerioideae species are very variable. The Ovary (botany), ovary may be superior, semi-inferior or inferior, and the fruit takes various forms. Taxonomy The original use of the name for the subfamily is attributed to Gilbert Thomas Burnett in 1835. Burnett divide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negria Rhabdothamnoides
''Negria'' is a plant genus in the family Gesneriaceae. Its only species is ''Negria rhabdothamnoides'', commonly known as the pumpkin tree. It is related to '' Fieldia'' (syn. ''Lenbrassia'') and ''Depanthus''. Description The pumpkin tree grows to about 8 m in height. It has pale, corky bark and soft, brittle wood. The ovate to broadly elliptic leaves are 70–200 mm long and 45–100 mm wide; they have glossy upper surfaces and are pale and sparsely haired beneath. The flowers are large and orange with small red dots, appearing over summer from October to April. The fruit is a black, beaked capsule 15 mm long which holds numerous tiny, wind-dispersed seeds. Distribution and habitat The species is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea The Tasman Sea is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction Debt
In ecology, extinction debt is the future extinction of species due to events in the past. The phrases dead clade walking and survival without recovery express the same idea. Extinction debt occurs because of time delays between impacts on a species, such as destruction of habitat, and the species' ultimate disappearance. For instance, long-lived trees may survive for many years even after reproduction of new trees has become impossible, and thus they may be committed to extinction. Technically, extinction debt generally refers to the ''number of species'' in an area likely to become extinct, rather than the prospects of any one species, but colloquially it refers to any occurrence of delayed extinction. Extinction debt may be local or global, but most examples are local as these are easier to observe and model. It is most likely to be found in long-lived species and species with very specific habitat requirements (specialists). Extinction debt has important implications for cons ...

Silvereye
The silvereye or wax-eye (''Zosterops lateralis''), also known by its Māori name tauhou, is a very small omnivorous passerine bird of the south-west Pacific. In Australia and New Zealand its common name is sometimes white-eye, but this name is more commonly used to refer to all members of the genus ''Zosterops'', or the entire family Zosteropidae. In New Zealand, the silvereye was first recorded in 1832. It arrived in greater numbers in 1856, and it is assumed that a migrating flock was swept eastwards by a storm. As an apparently self-introduced bird it is protected as a native New Zealand species. Its Māori name, , means "stranger" or more literally, "new arrival". Taxonomy The silvereye was first described by the English ornithologist John Latham in 1801 under the binomial name ''Sylvia lateralis''. There are 17 subspecies: * ''Z. l. chlorocephalus'' A. J. Campbell & S. A. White, 1910 ( Capricorn silvereye)– Capricorn and Bunker Group, central Queensland, Australia * ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stitchbird
The stitchbird or hihi (''Notiomystis cincta'') is a honeyeater-like bird endemic to the North Island and adjacent offshore islands of New Zealand. Its evolutionary relationships have long puzzled ornithologists, but it is now classed as the only member of its own family, the Notiomystidae. It is rare, being extirpated everywhere except Little Barrier Island, but has been reintroduced to two other island sanctuaries and four locations on the North Island mainland.Adams (2019). Current population estimations for mature individuals in the wild are 2,500–3,400. In addition to hihi, the stitchbird is also known by a number of other Māori names, including: tihi, ihi, tihe, kotihe, tiora, tiheora, tioro, kotihe-wera (male only), hihi-paka (male only), hihi-matakiore (female only), mata-kiore (female only), tihe-kiore (female only).

Tūī
The tūī (''Prosthemadera novaeseelandiae'') is a medium-sized bird native to New Zealand. It is blue, green, and bronze coloured with a distinctive white throat tuft (poi). It is an endemism, endemic passerine bird of New Zealand, and the only species in the genus ''Prosthemadera''. It is one of the largest species in the diverse Australasian honeyeater family Meliphagidae, and one of two living species of that family found in New Zealand, the other being the New Zealand bellbird (''Anthornis melanura''). The tūī has a wide distribution in the archipelago, ranging from the subtropical Kermadec Islands to the sub-Antarctic Auckland Islands, as well as the main islands. Taxonomy Europeans first encountered the tūī in 1770 at Queen Charlotte Sound / Tōtaranui, Queen Charlotte Sound on the north coast of New Zealand's South Island during James Cook, Captain James Cook's First voyage of James Cook, first voyage to the Pacific Ocean. Specimens were brought back to England an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
