One of the most little known species of ants in North America is the leaf-cutter ant. This is mainly because it lives in tropical environments and it is not aggressive to animals or humans if not disturbed. The leaf cutting ant is a social insect. Alone the ant is virtually helpless but with the colony it can be a thing feared by animal and human alike.
The leaf-cutting ants have a very important role in the tropical forest. They create and manipulate the environment around them. They also can do major damage. The leaf-cutting or fungus-growing ants are distributed from northern Texas to central Argentina.
These ants are injurious since they cut the green vegetation from trees, shrubs and crops, and carry it into the nest, where they cultivate fungi on it. They have been known to denude a tree or ornamental plants in one night. It has been estimated they do $1 billion damage per year in North and South America today, these ants still cause millions of dollars in crop losses in many South American countries. Although primarily an agricultural pest, this insect on occasion may invade the home for cereals. In the United States, the Texas leaf-cutting ant, Atta texana , occurs in Texas and Louisiana.
This ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998).There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the family called Formicidae, the family of ants (Hoyt. 1996). The leaf cutting ant belongs to the genus called Atta. There are fifteen different species of Atta and all are limited to the new world (Holldobler & Wilson, 1994).
The leaf-cutter ant looks pretty much like a regular ant in North America except that it is a little bigger than most ants. Looking at the ant in the untrained eye a person usually perceives that it is a primitive organism. Looks can be deceiving. The leaf-cutter ant is a complex superorganism unique social, environmental, and food gathering behavior.The anatomy of the leaf-cutter ant is pretty simple. It has a one segment "waist" (pedicel) between thorax and abdomen.
Sharp spines on waist and backward from head. Antennae 11-segmented very long and elbowed without distinct club. The legs are very long. This ant can be light to dark reddish brown (Smith. 1997).The leaf-cutter at is just li...

The inspiring documentary film, E.O. Wilson—Of Ants and Men, showcases biologist Edward Osborne Wilson’s passion for preserving the biodiversity of our natural world. E.O. Wilson not only values the fascinating creatures (particularly ants) that he comes across during his research and in his daily life, but he also takes action and participates in the Gorongosa Restoration Project at Gorongosa National Park in Mozambique, Africa. The destruction of Gorongosa demonstrates the call for us—Homo sapiens—to realize how critical it is to concern ourselves with protecting the very ecosystems that have molded us into the complex species that we are; according to E.O. Wilson, “We adapted over millions of years to wild environments…We really need them” (CITE?). The better effort we make to understand that we are a part of this large, interdependent ecological community, the better equipped we become in not only being
Celia, A Slave is a novel that narrates a teenage girl from located in the banks of the Missouri river in Calloway County. The story of the young girl defined the significance Gender in this historical discourse of this young slave. The newly settled slave holders in Calloway County in 1850 have included Robert Newsom who was a man of statute in terms of wealth and power. This is manifested in the novel because many slaveholders made their living by purchasing slaves. The reflection of this is the case of Robert Newsom who made his living by buying six slaves who will be responsible. He was very successful man both economically and socially and also a very powerful individual among the member of his household. But the death of his wife did take a significant turn of his life. The death of his partner forces him to seek for a replacement by purchasing a slave who will substitute his sexual desire that he was misses from his decease wife. Newsom embarked on a trip and bought Celia, A slave who was then fourteen year old and the relationship between master and slave established a sexual nature that will ever change until tragic took place.
Primarily, Celia’s story reveals many difficulties that were particularly faced by female slaves. In no
Celia, A Slave by Melton McLaurin tells a true story of a female slave who was sexually exploited by her master and the trial she faced as a result. At the young age of fourteen, Celia was brought to Callaway County under her new master, Robert Newsom. Celia later murdered Newsom, in an act of self-defense, and was placed on a trial challenging the institute of slavery and the moral beliefs of anyone involved with slavery in the South. The short life of the young Celia revealed a slave girl who had pushed beyond the ideal limit of a system that denied her humanity and threatened to erode the base of the antebellum southern society.
But the ants that showed up at our experiment were total morons. You'd watch one, and it would sprint up to a Cocoa Krispie, and then stop suddenly, as if saying: "Yikes! Compared with me, this Cocoa Krispie is the size of a Buick!" then it would sprint off in a random direction. Sometimes it would sprint back; sometimes it would sprint to another Cocoa Krispie and act surprised again. but it never seemed to do anything. There were thousands of ants behaving this way, and every single time two of them met, they'd both stop and exchange "high-fives" with their antennas, along with, I assume, some kind of ant pleasantries ("Hi Bob! "No, I'm Bill!" "Sorry! You look just like Bob!"). This was repeated millions of times. I watched these ants for two days, and they accomplished nothing. It was exactly like highway construction. It wouldn't have surprised me if some ants started waving orange flags to direct other insects around the area.
Celia, a Slave is a true story of a fourteen-year-old female slave purchased from Audrain County, Missouri by a wealthy, middle-aged, widowed, landowner named Robert Newsom from Callaway County, Missouri. Celia was the first woman of five slaves Newsom owned. She was purchased to take the place of Newsom’s late wife. In 1855, Celia was charged with killing her master after being continuously raped by him for several years. In Melton McLaurin’s Celia, A Slave, McLaurin exemplifies the oppressive difficulties of a female slave in Missouri in the 1850s.
Ants form colonies that range in size from a few dozen predatory individuals living in
The production of new ideas spark momentum for thought, the fabrication of machinery paves the way for innovations, and the expansion of human connection has led to new forms of participation. Historically, eras have been defined by the highlights of its period: the Stone Age allowed the development of tools while the Gold Age refined methods already produced to be more efficient in their purposes. If these are the things that define these eras, what has defined the twenty first century? In the later parts of the twentieth century, new technology like computer software ignited the world in a way never seen before. People all around the world were given access to connect with one another through the click of a button, and from there, the possibilities
Through her autobiography, Incidents in the Life of a Slave Girl, Harriet Jacobs, under the pseudonym Linda Brent, documents her story under slavery and her escape to freedom for her and her children and is addressed to the “people of the Free States” (Jacobs 3) who do not fully comprehend the evils of slavery. She makes appeals to expand their knowledge of the matter and states “only by experience can any one realize how deep, and dark, and foul is that pit of abominations” (Jacobs 3). As she recounts, Jacobs was born into slavery and after the death of her parents at a young age, and was raised by her free colored grandmother. Jacobs then spends the next twenty years under her mistress’s father, Dr.
Celia, a Slave, a book by author Melton McLaurin, shows the typical relationship between a slave woman and her master in America during the 1850s. The story is the perfect example of how relationships between slave and their masters and other non-blacks within the community. This is shown through Celia’s murder of her slave owner, Robert Newsom. It was also shown through the community’s reaction that was involved in unraveling her court case. The Celia personal story illustrated how slave women was treated by their slave owners and how the laws wasn’t effective at protecting slave during the 1850s. Celia’s story help shed light on woman injustices, unconstitutional rights and most importantly racial issues/discrimination.
Women who were enslaved during the slave period endured much suffrage. Not only were they the subject of chattel slavery, but some were also molested by their masters, for their own personal pleasure. In some cases, masters would pair “good breeders” together so their farm would benefit and they would have more slaves. This behavior would lead to force rape. The purpose of the book is to demonstrate how slavery crippled African American slaves from defending themselves due to oppression, particularly women. The trial of Celia, A Slave opens a gateway where people’s morals and actions were put into question after the death of her master. Themes such as gender oppression, chattel slavery, race, prejudice, revolt are some themes present in Celia,

In conclusion, women were considered property and slave holders treated them as they pleased. We come to understand that there was no law that gave protection to female slaves. Harriet Jacob’s narrative shows the true face of how slaveholders treated young female slave. The female slaves were sexually exploited which damaged them physically and psychologically. Furthermore it details how the slave holder violated the most sacred commandment of nature by corrupting the self respect and virtue of the female slave. Harriet Jacob writes this narrative not to ask for pity or to be sympathized but rather to show the white people to be aware of how female slaves constantly faced sexual exploitation which damaged their body and soul.
The destruction of this forest releases 340 million tons of carbon per year according to the World Wildlife Foundation, or WWF, which in turn causes climate changes everywhere around the world. Undiscovered species can hold the key to curing a plethora of diseases, but if those species become extinct, those keys are lost forever. If nothing is done to prevent this, the world’s treasure trove of bio-diversity will cease to exist, creating irreversible damage to not only the South American people, but also the rest of the world. Conversion of the tropical forest into cropland and pasture began a long time ago in Ecuador, before its secession from Spain. Their major crop was cocoa, which was grown along the waterways to be exported as their main source of trade.
Stones become hot from the sun and remain warm during the night. The warmth will radiate down into the nest and keep the young and older ants warm. Ants are social insects. Most insects have no family life, but ants are different. Ants have families and live in communities.
