Species After Extinction

The Sixth Extinction: An Unnatural History details the continued loss of biodiversity that has occurred since the rise of mankind. Elizabeth Kolbert claims that we are now in the midst of a sixth mass extinction, and that, if precautionary measures are not taken, the loss of biodiversity would be catastrophic. Chapter one begins by describing the golden frogs in the town of El Valle de Antón, and how they were beginning to disappear. The frogs disappeared due to a fungus called Batrachochytrium dendrobatidis. This fungus has spread around the world at a lightning-quick rate, killing all sorts of amphibious organisms at an unnatural rate. The cause of the rapid spreading of the fungus has been theorized to be due to humans inadvertently spreading

In nature, there are cases where species go extinct due to humans or for uncontrollable reasons. Recent scientific development has allowed a new idea called de-extinction the act of cloning extinct species using DNA samples from the past and biotechnology. However, extinct species should not be brought back to existence as the idea of de-extinction diverts attention and funding from protecting many endangered species that can still thrive in their environment. Another issue that arises with de-extinction is that resurrected species could become pests in their new environment.

The advent of functional analysis (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) and functional assessments (Dunlap & Kern, 1993) have provided behavior analysists with great ability to provide effective treatment for their clients. One common topic of research is the treatment of escape-maintained behaviors.

Chapter two start off with a story about rhinoceros and the reason behind why black rhinos became an endangered species. Some examples used in the book show that if a material object draws in a profit, it is okay, but when they no longer have purpose, then they become expendable. Author Wheelan illustrates that this has nothing to do with compassion but everything to do with maximizing the profit of that limited resource. He emphasizes the concept that almost all things in life boil down to economics. Incentives are the best influences that motivate individuals.

The Cretaceous-Tertiary extinction or K-T extinction, which marks the Late Cretaceous, is a massive and large-scale extinction of animal and plant species that occurred over a short period of time 66 million years ago.

Imagine walking in your backyard and seeing a dangerous buffalo that is twice the size as a cow eating your grass. That would be terrifying to witness, but that scene would most likely not happen in today’s world because the bison were almost driven to extinction during the 19th and 20th century. The Indians needed buffalo for their primary food source, so they would hunt bison. Then, Euro-Americans came along and disrupted the system for the Indians. There is an argument for who is to blame for the near-extinction of the bison. Some believe the blame all falls on the Indians as they over-hunted. Others may feel that the blame goes on the Euro-Americans who impacted the system by getting involved with bison. Consequently, I believe

I chose to focus on the most recent extinction: The Cretaceous Event. This mass extinction happened at least 65 million years ago and wiped out 76% of the Earth’s species. According to our textbooks there are many explanations as to what happened.The first one states that there had been a comet or asteroid that impacted Mexico’s Yucatan Peninsula and then that caused global destruction and rapid cooling. Another explanation that scientists have come up with is an increase in volcanic eruptions. Both explanations could have lead to the sky being clouded with debris. The Earth was then deprived of solar energy and photosynthesis could not occur resulting in the death of many plants, this then lead to the disruption of the food chain. Other alternative

The extinction of the megafauna round the world was most likely as a result of environmental and ecological factors. It's believed that megafauna came into existence in response to polar conditions and have become extinct with the commencement of hotter climates. the speculation of changes in climate state that the climate dried out as a result of the ice age. which then caused the rain forest to reduce. within the earth's lifetime we know that seven ice ages have occurred, creating the earth's temperature drop to -7.7 to -12.7 degrees celsius. By determining the most recent iceage, we are able to see if it occurred at the same time as the extinction of the megafauna, if so it would be thought of strong evidence thatclimate change was the

A clear analysis shows that extinction has occurred so much, that they do not only list the animals, they have to list a broader and more general title, meaning extinction is so worst that writing the names of the animals' name will be too much, and writing the whole broad title will include thousands of animals under one title. With 41% amphibian, 26% of mammal species and 13% of birds. It is extremely alarming. And the extinction only includes the species that has been found and labeled by us, there are much more species that have not been discovered if any of those species goes extinct we would have never known they existed in the first place. The fact that the sixth extinction is compared to the mass extinction of wipe out that happened

From the 17th century to 20th century, over 300 years, countries gradually becoming modern and human civilization developed rapidly. We changed the earth little by little, we paid more attention on how to improve the technique we had, at the same time we forgot to protect our environment which resulted many species of animals are in danger of becoming extinct. From a research it shows there are 16,928 listed endangered and 905 are already extinct.

It is my opinion, the importance lies in preventing species from going extinct. Many reasons exist behind the making of my decision, such as one significant change in a single species changes the environment and causes drastic effects. In addition, every single organism has a special activity in the ecosystem. The extinction of a species leads to ecosystem instability, as each organism plays an important role. Extinction of a species may not show an immediate effect, but the extinction of the main species leads to complete disruption of the ecosystem, and, loss of the genes, taking away important genetic resources.

Humans are the cause of mass extinction, in just 500 years,humans have been the cause of 322 animal extinctions, with two thirds of those occurring in the last century alone. Humans are making animals, endangered, or extinct; by our hunting, killing habitats, and most of all pollution. We should start making the Earth more friendly, for animals, and less deadly.

There have been five well known extinctions on this earth. The one most well known is the mass extinction that ended the dinosaurs. Mass extinction is often described as the elimination of a large number of species in a short period of time. Despite what many think, the elimination of species is almost commonplace at this point. The Earth is currently in the middle of a sixth mass extinction, and it’s been caused by the human race.

An ecological niche refers to an organism’s way of life - where it lives, its habitat, how it lives there and its adaptions. The radiate limpet lives in the low tide zone of the rocky platforms whereas the ornate

The extinction of dinosaurs could have been caused by many different things. One main reason that is thought around the world is that dinosaurs went extinct because an asteroid fell onto earth at speeds that are too fast for the human mind to even imagine. This idea was thought when and asteroid crater was found near mexico. Also to support the facts many scientist found traces of rare metal onto the earth's surface. This metal is not very common here but is really common in outer space. Today we will be looking at why these huge creatures died of the face of the planet in just a matter of months.
