Dione (alga)
''Dione arcuata'', commonly known as eyelash seaweed, is the only species of the red algae genus ''Dione''. The specific name ''arcuata'' comes from Latin and refers to the bow-like curved shape of the algae, while the generic name ''Dione'' is another name for the goddess Venus. It is made of filaments that are around 1.5 centimeters long; they are curved, wide, and do not split into branches. Taxonomy The first collection of the algae was made in 2000, and it was marked as a potential new species. Eyelash seaweed was first analyzed in a 2004 study on the genus '' Bangia''. It was initially called "''Bangia'' sp. BKE" and its genetic dissimilarity to other species in ''Bangia'' was noted. ''Dione arcuata'' was first formally described by Wendy Nelson in 2005, along with the related alga '' Minerva aenigmata''. Nelson split both species from ''Bangia'' based on morphological, habitat, and genetic differences. Ecology Eyelash seaweed is endemic to New Zealand and can be ...

New Zealand Threat Classification System
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protist A protist ( ) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus.

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Protists Described In 2005
A protist ( ) or protoctist is any Eukaryote, eukaryotic organism that is not an animal, Embryophyte, land plant, or fungus. Protists do not form a Clade, natural group, or clade, but are a Paraphyly, paraphyletic grouping of all descendants of the last eukaryotic common ancestor excluding land plants, animals, and fungi. Protists were historically regarded as a separate taxonomic rank, taxonomic kingdom (biology), kingdom known as Protista or Protoctista. With the advent of phylogenetic analysis and electron microscopy studies, the use of Protista as a formal taxon was gradually abandoned. In modern classifications, protists are spread across several eukaryotic clades called supergroup (biology), supergroups, such as Archaeplastida (photoautotrophs that includes land plants), SAR supergroup, SAR, Obazoa (which includes fungi and animals), Amoebozoa and "Excavata". Protists represent an extremely large genetic diversity, genetic and ecological diversity in all environments, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bangiophyceae
Bangiophyceae is a class of red algae that includes the order Bangiales and possibly Goniotrichales. In some classifications it is merged with the Florideophyceae to form the Rhodophyceae. The Bangiophyceae, as defined traditionally, are paraphyletic. Their taxonomic identification has been difficult because of a lack of distinct morphological features, and the presumed morphological plasticity of the species. Molecular tools are required to elucidate the relationships within this assemblage. It is still used by some sources, and defined ''sensu stricto'' (including '' Bangia'' and '' Porphyra'' but not the species included in Florideophyceae Florideophyceae is a class of exclusively multicellular red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to ex ...) is considered a valid clade. Notes References {{Taxonbar, from=Q1349723 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Critter Of The Week
''Critter of the Week'' is a weekly RNZ National programme about endangered and neglected native plants and animals of New Zealand. Beginning in 2015, ''Critter of the Week'' is an approximately 15-minute discussion between Nicola Toki (originally the Department of Conservation Threatened Species Ambassador) and RNZ Afternoons host Jesse Mulligan on an "uncharismatic and lovable" New Zealand species. Despite its name, the show features animals, plants, and fungi, with each species receiving an "attractiveness" score from 1 to 10. The show currently airs on Friday afternoons, and has a regular listenership of 100,000. Origin and development The topic of spotlighting uncharismatic species was raised in an interview by Mulligan in April 2015, and the programme originated later in 2015 in a discussion between Mulligan and Toki about threatened bird conservation, in which Toki lamented a lack of attention and corporate funding for species such as the '' Smeagol'' gravel slug. ...

2016 Kaikōura Earthquake
The 2016 Kaikōura earthquake was a 7.8 earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016 Time in New Zealand, NZDT (11:02 on 13 November UTC). earthquake rupture, Ruptures occurred on multiple fault (geology), faults and the earthquake has been described as the "most complex earthquake ever studied". It has been subsequently modelled as having a megathrust component set off by an adjacent rupture on the Humps Fault. It was the second largest earthquake in New Zealand since European settlement. The earthquake started at about north-east of Culverden and south-west of the tourist town of Kaikōura and at a depth of approximately . The complex sequence of ruptures lasted about two minutes. The cumulative magnitude of the ruptures was 7.8, with the largest amount of that energy released far to the north of the epicentre. Over 45,000 insurance claims were received, resulting in a loss of New Zealand dollar, NZ$2.27 billi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bangiales
Bangiales is an order of multicellular red algae of the class Bangiophyceae containing the families Bangiaceae, Granufilaceae, and possibly the extinct genus ''Rafatazmia'' with one species, ''Rafatazmia chitrakootensis''. They are one of the oldest eukaryotic organisms, possibly dating back to 1.6 billion years old. Many species are used today as food in different cultures worldwide. Their sizes range from microscopic ('' Bangiomorpha'') to up to two meters long ('' Wildemania occidentalis''). Many of its species are affected by '' Pythium porphyrae'', a parasitic oomycete. Similar to many other species of red algae, they reproduce both asexually and sexually. They can be both filamentous or foliose, and are found worldwide. History The first categorization of red algae currently placed inside Bangiales was the now-deprecated genus '' Phyllona'' by botanist John Hill in 1773. Bangiales itself was first categorized by Carl Nägeli in 1847. However, Bangiaceae had been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island ( , 'the waters of Pounamu, Greenstone') is the largest of the three major islands of New Zealand by surface area, the others being the smaller but more populous North Island and Stewart Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, to the south by the Foveaux Strait and Southern Ocean, and to the east by the Pacific Ocean. The South Island covers , making it the List of islands by area, world's 12th-largest island, constituting 56% of New Zealand's land area. At low altitudes, it has an oceanic climate. The most populous cities are Christchurch, Dunedin, Nelson, New Zealand, Nelson and Invercargill. Prior to European settlement, Te Waipounamu was sparsely populated by three major iwi – Kāi Tahu, Kāti Māmoe, and the historical Waitaha (South Island iwi), Waitaha – with major settlements including in Kaiapoi Pā near modern-day Christchurch.
