Endangered Languages CONOR MCDONOUGH QUINN Languages that are threatened with the loss of natural generational transmission are referred to as endangered languages. Language endangerment generally occurs in the later stages of language shift‚ that is‚ when a speech community moves away from their earlier variety‚ dialect‚ or language to a new one or new set thereof (Fishman‚ 1991). While the processes of endangerment and extinction have likely been constant throughout the history of human language
Premium Language death Linguistics
“Endangered languages should be saved” Many languages are at the danger of disappearance. The reason of their extinction could be the decrease in a number of people speaking that language. A 85% of 6000 languages appear to be spoken in 25 countries (NOW 2000). Language extinction is caused by external and internal factors. Internal forces such as community’s negative behaviour to mother language‚ or simply decrease in the number of speakers are mainly derived from factors such as military‚ economic

animalinfo.org‚ there are more and more animals becoming endangered every year throughout the world. Interestingly‚ the Mediterranean Monk Seal is recorded as one of the most critically endangered animals in Italy. Currently‚ the population of that species has been reduced about ten times compared to the period of the 1950s (1). This issue highly damages the nation. Apparently‚ zoologists and travelers do not have opportunities to study about that species so Italy can no longer be a choice for visitors leading

The species richness is when we talk about the actual number of species in a community. For example‚ if you go to a bottom ground forest you might see only sugar maple. Therefore‚ the species richness is only 1. Shannon Index measures species diversity too‚ but takes into account species evenness. Species evenness is when the relative abundance of the species in that community are more similar to each other. So by knowing that you have more similar species‚ this allows you to more accurately determine

KEYSTONE SPECIES-BEES Elliott Chang Keystone Species are species that would affect our lifestyle and how we live if they were to die out. There called Keystone Species because in an arch‚ there is one stone that keeps the 2 halves of the arch in place and if you were to take it out‚ everything would collapse. Bees are like that. Bees contribute to our society economically‚ ecologically and biologically. They are the species that really make everything the way it is for us. Bees contribute

Keystone species play a large role in each ecosystem‚ they have the ability to alter their ecosystem or be the reason they completely collapse. Keystone species are the reason that many different species exist‚ these other species highly depend on the keystone species for survival‚ if a single keystone species were to go extinct‚ it is likely for other species populations to decrease. Other species benefit from keystone species in a variety of ways‚ such as food supply‚ shelter‚ or a water source

is an eagle subspecies that belong to the family of Accipitridae and is native to Philippine. These eagle display white-colored plumage together with the shaggy crest‚ averaging 86 – 102 cm (2 ft 10 in to 3 ft 4 in) in length. The weight of these species measure around 4.7 – 8 kg (10 – 18 lb). As far as the eagle’s length is concerned‚ Philippine eagle is the largest‚ harpy eagle and the stellar’s sea eagle being the other contenders. They are also regarded as the rarest and the most powerful birds

On the Origin of Species chapter IV outlines Darwin’s proposal on how a new species is generated via natural selection over a long period of time. In Darwin’s theory of speciation‚ he proposes that all organisms within a species must express some degree of variation‚ which allow for organisms with the most advantageous variations to produce the most offspring (Darwin 10) This also means that the variations must be heritable from one generation to the next. In chapter IV Darwin uses the examples variants

Ring Species: A Catalyst for Speciation After spending time on the Galapagos Islands studying the origin of various species‚ former divinest Charles R. Darwin proposed the evolutionary theory of natural selection‚ a mechanism by which advantageous variations in a population are preserved while unfavorable variations are lost (Berkeley‚ 2008). As a result of these variations‚ some individuals are better acclimated to their environment than others. This results in the better-suited individuals outcompeting
