Durvillaea Willana
''Durvillaea willana'' is a large species of Durvillaea, southern bull kelp Endemism, endemic to New Zealand. Etymology The species epithet, ''willana'', honours Eileen Alice Willa who collected many algal species for Lindauer. Description This species is chocolate brown in colour and is darker than all other bull kelp species. It has a branched stipe. The species is non-buoyant and does not have 'honeycomb' in its fronds. The holdfast becomes large and spreads like a plate on rocky substrates. This species is superficially similar in appearance to ''Durvillaea antarctica''. However, ''D. willana'' has smaller blades than ''D. antarctica'' and is usually found lower on the shoreline because its lower tolerance of wave action comparded ''D. antarctica''. It also has a branched stipe and does not have buoyant fronds, unlike ''D. antarctica''. Distribution This species of kelp is endemic to New Zealand and is found on the southeastern shores of the North Island, although not in ...

Victor Wilhelm Lindauer
Victor Wilhelm Lindauer (1888–1964) was a New Zealand phycologist, collector and teacher. The son of New Zealand painter Gottfried Lindauer, he was born in 1888 in Auckland, and grew up in Woodville, spending a considerable part of his boyhood in the native bush. He trained as a teacher and after two years service in WWI with the US Army, he returned to New Zealand. In 1927 Lindauer married Elsie (née Lovell), and in 1931, after the births of four children, the family moved to Russell where he had been appointed headmaster of the primary school. In 1935, Josephine Tilden and a team of phycologists from the University of Minnesota came to Russell to collect seaweeds and enlisted his help to provide a place (the local school) to handle their material. They also invited him to participate, and thus began his lifelong quest to collect New Zealand seaweeds. The school children whom he taught collected for him and with him. Other schoolmasters were also enlisted, not only on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Durvillaea
''Durvillaea'' is a genus of large brown algae in the monotypic family Durvillaeaceae. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. ''Durvillaea'', commonly known as southern bull kelps, occur on rocky, wave-exposed shorelines and provide a habitat for numerous intertidal organisms. Many species exhibit a honeycomb-like structure in their fronds that provides buoyancy, which allows individuals detached from substrates to raft alive at sea, permitting dispersal for hundreds of days over thousands of kilometres. ''Durvillaea'' species have been used for clothing, tools and as a food source by many indigenous cultures throughout the South Pacific, and they continue to play a prominent role in Chilean cuisine. Common name and etymology The common name for ''Durvillaea'' is southern bull kelp, although this is often shortened to bull kelp, which can generate confusion with the North Pa ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...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 ...

Eileen Alice Willa
Eileen Alice Willa (1905–1999) was a New Zealand botanical collector, museum curator and writer. She was born Eileen Harrison on Stewart Island, and grew up with a love of botany. In 1928, she married Percy Willa and they settled at Halfmoon Bay, Stewart Island. While Percy fished, she explored and collected plants. In 1943, Victor Lindauer, a New Zealand algae collector, asked her to collect seaweeds from Stewart Island, to help him in his work. She sent many specimens, and from this time she started collecting seaweeds (as well as land plants). Like Lindauer, she too, hosted scientific teams visiting her home (Stewart Island). Three species of seaweed honour Eileen Willa: '' Ptilonia willana'' (found at Port Pegasus in 1945), the large brown kelp, ''Durvillaea willana'' ( Broad Bay, 1946) and '' Crouania willae'' (Ringaringa, 1960). In 1974 with three others, she co-authored the publicatio"The Marine Algae of Stewart Island" A museum at Rakiura was established, showing ...

Taieri Island / Moturata
Moturata, also called Taieri Island, is an island in the mouth of the Taieri River in southern New Zealand. It is connected to the mainland by a sandy causeway at low tide. The island is a nature reserve, and is home to many protected seabirds, notably yellow-eyed penguins. It was the site of a whaling station, primarily targeting southern right whales and secondly humpbacks and others in the 1830s and 40s. Many shore-whaling stations were operating all around New Zealand's coastline in this time, causing whale numbers to deplete to almost extinction. Today, whales are making a comeback slowly, occasionally being seen in this area in their migrating season. In June 2006, a pod of four southern right whales were seen frolicking off Taieri Mouth. The group was composed of 3 males and 1 female, thought to be a mating group, which had not been observed in the waters of New Zealand for long period. History Taieri Island may have been the "Isle of Wight" where ''The Brothers'', a Sydne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1855 Wairarapa Earthquake
The 1855 Wairarapa earthquake occurred on 23 January at about 9.17 p.m., affecting much of the Cook Strait area of New Zealand, including Marlborough in the South Island and Wellington and the Wairarapa in the North Island. In Wellington, close to the epicentre, shaking lasted for at least 50 seconds. The moment magnitude of the earthquake has been estimated as 8.2, the most powerful recorded in New Zealand since systematic European colonisation began in 1840. This earthquake was associated with the largest observed movement on a strike-slip fault, maximum . It has been suggested that the surface rupture formed by this event helped influence Charles Lyell to link earthquakes with rapid movement on faults. Tectonic setting New Zealand lies along the boundary between the Australian and Pacific Plates. In the South Island most of the relative displacement between these plates is taken up along a single dextral (right lateral) strike-slip fault with a major reverse component, t ...
