Angonoka Tortoise Facts

Angonoka Tortoise Facts The angonoka tortoise (Astrochelys yniphora), also known as the ploughshare or Madagascar tortoise, is a critically endangered species that is endemic to Madagascar. These tortoises have unique shell colorations, a characteristic that makes them a sought-after commodity in the exotic pet trade. In March of 2013, smugglers were caught transporting 54 live angonoka tortoises- nearly 13 percent of the entire remaining population- through an airport in Thailand. Fast Facts: Angonoka Tortoise Scientific Name: Astrochelys yniphoraCommon Names: Angonoka tortoise, ploughshare tortoise, plowshare tortoise, Madagascar tortoiseBasic Animal Group: ReptileSize: 15-17 inchesWeight: 19-23 poundsLifespan: 188 years (average)Diet: HerbivoreHabitat: Baly Bay area of northwestern MadagascarPopulation: 400Conservation Status:  Critically Endangered Description The angonoka tortoises carapace (upper shell) is highly arched and mottled brown in color. The shell has with prominent, ridged growth rings on each scute (shell segment). The gular (foremost) scute of the plastron (lower shell) is narrow and extends forward between the front legs, curving upward toward the neck. Habitat and Distribution The tortoise inhabits dry forests and bamboo-scrub habitats in the Baly Bay area of northwestern Madagascar, near the town of Soalala (including Baie de Baly National Park) where the elevation averages 160 feet above sea level. Diet and Behavior The angonoka tortoise grazes on grasses in open rocky areas of bamboo scrub. It will also browse on shrubs, forbs, herbs, and dried bamboo leaves. In addition to plant material, the tortoise has also been observed eating the dried feces of bush pigs. Reproduction and Offspring The reproductive season occurs from approximately Jan.15 to May 30, with both mating and egg hatching occurring at the onset of rainy seasons. The courtship begins when the male sniffs and then circles the female five to 30 times. The male then pushes and even bites the females head and limbs. The male literally overturns the female in order to mate. Both the males and female can have several mates during their lifetimes. A female tortoise produces one to six eggs per clutch and up to four clutches every year. The eggs incubate from 197 to 281 days. Newborn turtles are generally between about 1.7 and 1.8 inches and are completely independent once they are born. Angonoka tortoises reach maturity and become sexually active at about 20 years of age. Threats The greatest threat to the angonoka tortoise is from smugglers collecting them for the illegal pet trade. Secondly, the introduced bushpig preys on tortoises as well as its eggs and young. Additionally, fires employed to clear land for cattle grazing have destroyed the tortoises habitat. Collection for food over time has also impacted the angonoka tortoise population but to a lesser degree than the above activities. Conservation Status The IUCN classifies the northern leopard frogs conservation status as Critically Endangered. There are literally only about 400 angonoka tortoises remaining in Madagascar, the only place they are found on Earth. Their unique shell colorations make them a sought-after commodity in the exotic pet trade. It is the worlds most endangered tortoise, tortoise advocate Eric Goode said to CBS in a 2012 report on the  ploughshare. And it has an incredibly high price on its head. Asian countries love gold and this is a gold tortoise. And so literally, these are like gold bricks that one can pick up and sell. Conservation Efforts In addition to its IUCN listing, the angonoka tortoise is now protected under the national law of Madagascar and listed on Appendix I of CITES, prohibiting international trade in the species. The Durrell Wildlife Conservation Trust created Project Angonoka in 1986 in cooperation with the Water and Forests Department, the Durrell Trust, and the World Wide Fund (WWF). The Project performs research on the tortoise and develops conservation plans designed to integrate local communities in the protection of the tortoise and its habitat. Local people have participated in conservation activities such as building firebreaks to prevent wildfire spread and the creation of a national park that will help protect the tortoise and its habitat. A captive breeding facility was established for this species in Madagascar in 1986 by the Jersey Wildlife Preservation Trust (now the Durrell Trust) in cooperation with the Water and Forests Department.

Pronunciation Guide for Spanish Students

Pronunciation Guide for Spanish Students One reason many people pick Spanish as their choice for a foreign language is because theyve heard that its easy to learn its pronunciation. Indeed thats the case - even though some of the sounds can be difficult for foreigners to master. Its relative ease of pronunciation stems from the phonetic nature of Spanish: By knowing the spelling of a word, you can almost always know how its pronounced. The biggest exception is recent words of foreign origin, and in that case, you have a head start if you know English, because most such words come from English. The key, then, to learning Spanish spelling is to learn how each letter is pronounced. You can find guides to each of the letters on the following pages: Pronouncing the vowels: A, E, I, O, U, YPronouncing the easy consonants (ones pronounced roughly as they are in English): CH, F, K, M, P, Q, S, T, W, YPronouncing the difficult consonants (ones pronounced differently than in English): B, C, D, G, H, J, L, LL, N, Ñ, R, RR, V, X, Z Here are some general principles of Spanish pronunciation that you may find helpful: The vowel sounds of Spanish are usually purer than those of English. Although the vowel sounds of English can be indistinct - the a of about sounds much like the e of broken, for example - that isnt the case in Spanish.It is very common for sounds of words to blend together, especially when a word ends in the same letter that begins the next word. For example, helado (ice cream) and el lado are pronounced identically. This process is known as elision.Sounds of consonants tend to be softer or less explosive than they are in English. One notable example is the sound of the h, which has become so softened over the centuries that it is silent in modern speech.The rules on which syllable is stressed are clear and have limited exceptions. If a word has a nonstandard stress, a written accent  is placed over a vowel to indicate the correct stress. Unfortunately, although you can tell how a word is pronounced by its spelling, the reverse isnt always so. In fact, native Spanish speakers are often poor spellers. Thats because Spanish has a fair number of homophones   words that are spelled differently but pronounced alike.
