input: Please answer the following: This article: Three species of mangrove trees exist in the region: red (Rhizophora mangle), black (Avicennia germinans), and white (Laguncularia racemosa), although all are from different families. All have the same characteristics: they are tolerant of salt, brackish, and fresh water; they grow in oxygen-poor soil; and they can survive drastic water-level changes. Black and white mangroves excrete salt from under their leaves, and red mangroves filter the salinity of sea water. All species are integral to coastline protection during severe storms. Red mangroves, for example, have far-reaching roots that trap sediments. The trees not only stabilize coastlines, but add land as more sand and decaying vegetation is trapped in the root systems. All three mangroves also absorb the energy of waves and storm surges. The estuaries act as fisheries for fry and nurseries for crustaceans. Shrimp, oysters, crabs, whelks, cockles, and snails thrive in these waters, as do primordial horseshoe crabs (Limulus polyphemus). The region supports a $59 million-a-year Tortugas pink shrimp (Farfantepenaeus duorarum) industry, and a $22 million-a-year stone crab (Menippe mercenaria) industry. Between 80 and 90 percent of species that are harvested commercially in Florida are born or spend time in the shallow waters near the Everglades. Oysters and mangroves work in tandem to build up the coastline. The sand around the coastline has minute white particles of quartz and fine shells. When currents are right, oysters grow in colonies or beds, and deposit their shells, reinforcing the bed. Mangrove seeds, called propagules, are full embryos and float in water until they reach a favorable location and take root, often on oyster beds. They shed skin and litter, ensuring other trees will not compete for space and nutrients.Mangroves also serve as excellent rookeries for birds. Wading birds, such as roseate spoonbills (Platalea ajaja), egrets, and tricolored herons (Egretta tricolor) use the mangroves as a nursery, due to the proximity of food sources... contains an answer for the question: What are the full scientific names of the three species of mangrove trees that can survive drastic water-level changes?, what is it ?

Please answer this: This article: Nannerl herself was an apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activityat the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present. contains an answer for the question: What is the first name of the person who slipped on the polished floor?, what is it ?

input question: This article: Elgar was knighted at Buckingham Palace on 5 July 1904. The following month, he and his family moved to Plas Gwyn, a large house on the outskirts of Hereford, overlooking the River Wye, where they lived until 1911. Between 1902 and 1914, Elgar was, in Kennedy's words, at the zenith of popularity. He made four visits to the US, including one conducting tour, and earned considerable fees from the performance of his music. Between 1905 and 1908, he held the post of Peyton Professor of Music at the University of Birmingham. He had accepted the post reluctantly, feeling that a composer should not head a school of music. He was not at ease in the role, and his lectures caused controversy, with his attacks on the critics and on English music in general: "Vulgarity in the course of time may be refined. Vulgarity often goes with inventiveness ... but the commonplace mind can never be anything but commonplace. An Englishman will take you into a large room, beautifully proportioned, and will point out to you that it is white all over white and somebody will say, 'What exquisite taste'. You know in your own mind, in your own soul, that it is not taste at all, that it is the want of taste, that is mere evasion. English music is white, and evades everything." He regretted the controversy and was glad to hand on the post to his friend Granville Bantock in 1908. His new life as a celebrity was a mixed blessing to the highly strung Elgar, as it interrupted his privacy, and he often was in ill-health. He complained to Jaeger in 1903, "My life is one continual giving up of little things which I love." Both W. S. Gilbert and Thomas Hardy sought to collaborate with Elgar in this decade. Elgar refused, but would have collaborated with George Bernard Shaw had Shaw been willing.Elgar's principal composition in 1905 was the Introduction and Allegro for Strings, dedicated to Samuel Sanford, professor at Yale University. Elgar visited America in that year to conduct his music and to accept a doctorate from Yale. His next... contains an answer for the question: What work received a hundred performances in Britain, America and continental Europe in just over a year?, what is it ????
