Population growth concerns of African forest elephants
A scientific paper recently written by Turkalo et al, Slow intrinsic growth rate in forest elephants, indicates that the recovery of African forest elephants, Loxodonta cyclotis, from poaching will require several decades. This species of African elephant has been experiencing continual population declines driven by illegal killing (poaching) and natural habitat range loss. These scientists completed the 1st ever demographic study on African forest elephant populations. Since 2002, it’s estimated that their population has decreased by 62% and that they have lost 30% of their habitat range. Using data collected in Dzanga forest, located in the Central African Republic, scientists found that …show more content…
This article was very official looking and appears to be a popular ecological science output. It was a press release about the original article. Plane focuses on the African forest elephant has one of the worlds slower reproduction rates, and how poaching is effecting these populations. She explains how the forest and savannah African elephant differ in demography (i.e. period of time between offspring birth). Plane exaggerates on how long it would take the current forest elephant population to recover from the poaching; “The findings, published in the Journal of Applied Ecology, indicate it will take almost a century to recover from the poaching they have suffered since 2002” (Plane 2016) versus the approximate 60 year doubling time under current conditions stated in the original scientific journal. By using this exaggeration, I believe the author was trying to get a more compelling story rather than sticking to the underlying science. While not a major point of her article, Plane touches on the importance of the African forest using the phrase “absorbing climate change gases” (Plane 2016) instead of just carbon as stated in the Turkalo et al paper. The topic of “climate change” is fairly controversial in the present, and thus, I believe the addition of this controversial phrase was another attempt to get a more compelling …show more content…
I think the author’s use of a creative title, “Slow and Steady Wins the Race? Or Leads to Extinction?”, is attention grabbing. The blog plays on the common folk-tale of the Tortoise and the Hare, comparing the African forest elephant’s battle with their declining population to the original story. This post was more laid-back and uses Lehman terms much more than the other article, making it easier for people without a science background to understand. The author states that “some critics question the reliability of the mortality rate measured for forest elephants in Turkalo’s Wrege’s and Wittemyer’s study” (Slow and Steady 2016). They continue into an explanation of why the critics could think this. By the author adding this to their piece, I think it brings in the opposing side of the science and makes the post reliable. The rest of the post is consistent with Turkalo et al’s

Cites

...This paper aims to look at the Convention of International Trade in Endangered Species (CITES) and role it plays within the sustainable use paradigm in Zimbabwe in particular and some of the countries in Southern Africa. Here we will understand the meaning or definition of CITES and how the CITES convention has played a great role in the countries in Africa and around the world. To begin this discussion it is important to understand what the CITES Convention was all about. CITES was established as a response to growing concerns that over-exploitation of wildlife through international trade was contributing to the rapid decline of many species of plants and animals around the world. The Convention was signed by representatives from 80 countries in Washington, DC, United States, on 3 March 1973, and entered into force on 1 July 1975. As of December 2008, there are 173 parties to the Convention. The aim of CITES is to ensure that international trade of wild animal and plant species does not threaten their survival. The Convention's conservation goals are to: monitor and stop commercial international trade in endangered species; maintain species under international commercial exploitation; and assist countries toward sustainable use of species through international trade. CITES parties regulate wildlife trade through controls and regulations on species listed in three appendices. Appendix I lists species endangered due to international trade. Trade in such species is permitted...

Asian Elephant Research Paper

...Elephants are largely known as the world's biggest land mammals. A mature elephant is approximately 6300 kilograms in weight, and is up to 3.5 meters in height. There are two scientifically recognized species of elephants; the African elephant and the Asian elephant. The names of the two types of elephants correspond with the parts of the world where they largely live. The Asian elephant is the smaller of the two species. Interestingly, only the male Asian elephants have tusks. These Asian elephants use their single short lip, which resembles a finger, for sufficient handling of objects. The African elephants are well identified by their larger ears and tusks, rounded foreheads, and two finger-like lips on their trunks. Genetically, the African Elephant is further dived into two types; the African Bush (Savannah) elephant and the African Forest elephant. You can easily differentiate the two types of elephants by their tusk. In that, the African bush elephant has admirably curved tusks while the African forest elephant has moderately straight tusks that are often pointing downwards. Both the...

Social Injustice In Wisconsin

...A quote that effectively describes my attitude toward Milwaukee, WI, would be, “I love my hometown, but it’s also a great town. There are a lot of stories when you peel back the layers”. As I develop into an amateur social justice fighter, if I had the opportunity to solve a problem I would fix the many social injustices occurring in Milwaukee. Day after day I encounter social issues such as poverty, drug and alcohol abuse, violence, and segregation. In fact, my family’s life was infiltrated by these issues and caused significant damage to our familial bond. My desire to have peace does go to the extreme of wishing for a utopian ideal with absolute peace; however, I believe solving a few social injustices will lead towards a stable community. Solving poverty is the issue I regard as a priority in order to improve Milwaukee. The number of grown men and women begging for money on the streets surpasses the five fingers on each of my hands. Although at times I question the truthfulness of their lack of financial resources. Regardless, this signifies to me that there must have been significant poverty in order for others to want to disrespectfully take advantage and mock the poor. However, poverty in Milwaukee manifests beyond the streets; it also contributes to the infamous segregation of the city. The cost of housing typically determines where a family lives in the city. For example, the Southside of Milwaukee stereotypically houses low-income, Hispanic families and is where my...

Write An Essay On Keystone Species

...the habitat suffers. Many keystone species are predators who are essential to their habitat because they control the population of their prey. Without them, the prey would overpopulate and consume too many resources. When the resources are consumed, other species can no longer live. However, herbivores can be keystone species as well. One example of this is the African elephant, or Loxodonta africana. The African elephant is the world’s largest land mammal. They live in small family groups and have been known to grieve over dead family members. These creatures are in a state of vulnerability, they aren’t endangered yet, but they are close. This species is at high risk for becoming extinct in the wild. In African savannas such as the Serengeti plains region that covers parts of Kenya and Tanzania, elephants...

African Elephant

...The common name is the African Elephant, the scientific name is Loxodonta Africana, the phylum is Vertebrata, the class is Mammalia, the order is Proboscidea, and the family is Elephantidae. The Closest Relatives to the African Elephant are: the Asian Elephant, mammoths, primitive proboscidean (mastodons), sea cows, and hyraxes. Scientists believe that the African Elephant evolved from one of its closest relatives, the Sea Cow. The geographical location and range of the African elephant covers all of central and southern Africa. In Ethiopia there are isolated populations that exist around Lake Chad in Mali and Mauritania. Also in Kenya, Rhodesia, Tanzania, Zambia, Uganda, Zaire, and in National parks located in South Africa, as well as several other countries. African Elephants, originally, were found in all of the Sub-Saharan African habitats except desert steppes. Elephants still occupy diverse habitats such as: temperate grassland, tropical savanna and grass lands, temperate forest and rainforest, tropical rainforest, tropical scrub forest, and tropical deciduous forest despite their drastic decline in numbers. However, their migratory patterns and habitat use have changed, due to the fact that they are restricted to protected areas. The elephant can exist in many types of environments but it prefers places that have many trees and bushes, which the elephant needs both for food and shade. They also like warm areas that have plenty of rainfall. This ensures...

The generous profit of Ivory in Asia and lack of income opportunities is seemingly forcing innocent people, who are simply looking for a means of survival, to kill elephants for their tusks. In order for survival of families, elephant poaching has become a significant source of income in Africa. Because of this, total extinction of these majestic animals is becoming a very real possibility and studies show that sadly enough we are swiftly working towards that. Here we will discuss the scope of the issue (what, when, where and why), regulation efforts of the poaching and the projected future of the outcome of poaching. When I first heard about poaching...

...with elephants is beset by contradictions. On the one hand, they are regarded with awe and fascination; while on the other, whole populations are eradicated in pursuit of land or ivory (David 444). Even though elephants do have natural predators- the young are often killed by lions, hyenas, or crocodiles- by far their most dangerous enemy is humankind (David 444). As far back as classical antiquity, North African elephant populations were dwindling rapidly. They finally disappeared during the Dark or Middle Ages (“Saving the Elephant”). The Arab ivory trade, which started in the 17th century, precipitated a further rapid decline among elephant populations in both West and East Africa (“Saving the Elephant”). The colonial era accelerated the process by opening up previously inaccessible areas introducing modern technology, notably high-powered rifles; in Africa, the destruction of elephants reached a peak between 1830 and 1900 (“New Rules”). Today, continuing deforestation and the encroachment of roads, farms, and towns into former elephants habits threaten both African and Asian elephant by restricting their range, cutting off seasonal migration routes, and bringing them into more frequent conflict with people (“New Rules”). Perceptions of the main conservation issues involved have changed radically since the 1960s when the debate centered on local overpopulation of elephants in protected areas (David 444). In the 1970s and 1980s the concern was that elephants were being...

African Elephant Decline

...At one point in time the African elephant roamed a majority of the African Continent. In the early twentieth century it was estimated that approximately seven to ten million African elephants roamed the plains of Africa. In the most recent estimates this number had plummeted to a sparse three hundred thousand individuals and continues to decline at a rapid pace. Due to the incorrigible demand for ivory, along with habitat loss as a consequence of human settlement, has led to a sudden and steep decline decline in the populations of the elephants of Africa. Why does it matter that elephants are coming to extinction? The fact that many people fail to recognize is that elephants are a keystone species of the African ecosystem. For this reason the...
