Jazz Stephens presented on Does Incubation Behavior Influence Nestling Telomere Length? And Egg Gross-Foster Experiment In Barn Swallows. The research measured effects of telomere length of barn swallow based on specific environmental criteria. In barn swallows, it is known that telomere length is associated with survival, reproductive growth, and success. The research team analyzed how incubated temperature affects telomere length. This experiment was done by two methodologies. The first, cross-foster design, which decoupled genetic environments to analyze how telomere changes in different environments. To test the temperature within the nest, a fake egg was placed within the nest the recorded the continuous temperature within the nest.
The gall is made of plant tissue but aspects of genetically coded stimulus from the insect makes the gall from the normal plant tissue (Abrahamson, 1989). The gall can be many different sizes in diameter. Survival depends on the gall size, the smaller the galls means that the larvae is vulnerable to parasitoid oviposition, but when the galls are larger they are more likely to be attacked by avian predators (Abrahamson, 1989). Gallmaker enemies can influence the survival of individual gallmakers. The natural enemies of the gallmakers can have a potential effect and alter gallmaker traits for other generations if survivorship varies (Abrahamson, 1989). This study wanted to know three things, how many gallmakers there are as well as how many natural enemies there are, and to what extent of the goldenrod fly mortality was due to insect and bird enemies listed above. They also wanted to know what gall size did these natural enemies prefer and what kind of
Flying Tigers is the name of a mercenary group of American pilots that helped defend China and the Burma Road from the bombing of the Japanese during World War II. The name of their planes was Tomahawks, but the Chinese called them Fei Hu for the sharks teeth painted on their planes. Flying Tigers were known as the American Volunteer Group of the Chinese Air Force. The Flying Tigers did not see combat until December 1941 when the Japanese started bombing China.
On year 6, the rain level was in the right range for the whooping crane population, with the amount of rainfall at 8.1 cm, and the snowfall at 4.6 cm. This great weather resulted in 8 nests, 8 eggs laid, and 4 eggs hatched. It might not seem like a major population growth, but with this specific endangered species, its population growth isn’t as quick as many other species. This was the main reason why it brought the attention to many officials to protect the whooping cranes from extinction. In this particular year, the hatching success rate was at a 50%, which is surprising because this year was the one who brought up the population well, into year 7. The amount of rainfall in year 7 was 7.4cm, while the snowfall was 0.0cm. Once again, these were perfect conditions for the whooping cranes. This caused the overall crane population (including chicks), to increase by 8 cranes, from year 6 to year 7. The hatching success rate was a high of 83%, the highest it has ever been in the 16 years of data! You can obviously see here that these low precipitation conditions are very beneficial to the overall growth of this
Minstrels Minstrels, or traveling thespians, thrived throughout Europe in medieval times. The term minstrel referred to a professional entertainer of any kind from the 12th century to the 17th century. Minstrels were instrumentalist, but were also often jugglers, acrobats, and storytellers. Although minstrels no longer exist, they played an important role in medieval history and, at one time, could be found, in one form or another, throughout the entire continent of Europe. Different countries had different names for minstrels.
“It is my conviction that killing under the cloak of war is nothing but an act of murder,” Albert Einstein. The Vietnam War was a war that America did not need. America believed they were doing good. They believed that they were protecting the people of Vietnam. America did not realise that they were only making a bad situation worse. America stopped nothing. They didn’t stop communism; they didn’t save the people of Vietnam. America caused the number of casualties in Vietnam to increase and had their own people killed. They caused diseases and destroyed the environment with the help of Agent Orange. America sent soldiers on a mission with a result of hundreds of civilians murdered. America did not help anyone. America sent people out to murder others and to be killed in the line of duty.
Wild Swans Is a novel expressing the history and tradition of the Chinese culture through the eyes of one, Jung Chang. Jung Chang tells the story of a struggling China dealing with communism through three generations of women: her grandmother, her mother, and herself . Through her grandmother the traditional China is brought forth, and the reader is made aware of what it was like living in an older China. Her mother’s life introduces us to communism and how it began and spread throughout China. Jung Chang’s life displays what it was like living in a more recent China. Her family goes through many hardships as a result of communism, the Great Leap Forward, and The Cultural Revolution. The first major change in China was the establishment of communism.
Picture this for a second. You come home both mentally and physically exhausted after a strenuous day at school. All you want to do is watch TV and relax with your best friend. As you begin up the concrete cracked driveway, these thoughts linger in your mind. You push the key into the door handle but you notice something is wrong. There is no barking, no tail wagging, no sign of your best friend at the gate. All that is left is a notice on the front door explaining that your dog has been destroyed by the RSCPA.
To Kill a Mockingbird is about two children, Scout and Jem, growing up in a town called Maycomb, Alabama in the 1930's. Neighbors and a man next door with the name of Boo Radley make up most of the drama and suspense throughout the story. Scout and Jem put up with a bunch of trash talk when their father, Atticus, defends a black person. As the novel goes on, the children loose their innocence. They learn the injustice of the world when Tom Robinson, a black man falsely accused of rape, was convicted guilty. Harper Lee uses the symbol of the mockingbird to show that justice back in the old days isn't always the way it should be, but the exact opposite by using her characters as "mockingbirds." She wants to tell us that prejudice is more powerful than an equal legal system.
In this world, everyone has an equal right; however, many people are getting falsely accused of acts they did not commit even though they are innocent. Mockingbirds, one of the most innocent birds, sing their heart out for people to enjoy, however, they getting killed every day. In this novel, To Kill a Mockingbird, there are many racial prejudices going on. Finches stand near the top of the social hierarchy, with Cunningham and Ewells underneath. Black community in Maycomb is even below the Ewells, even if they were a hard worker; they were not treated equally. The “mockingbirds” represents the idea of innocence, so killing a mockingbird is to destroy innocence. Throughout the book, many characters are considered a mockingbird. Three examples are Tom Robinson, Boo Radley, and Mr. Dolphus Raymond. Those three characters are innocent; they are kind and were never harmful to others. However, they were destroyed through contact of evil. In the novel, To Kill a Mockingbird, by Harper Lee, the mockingbirds symbolizes the idea of innocence, and Tom, Boo, and Mr. Raymond are considered one of it.

In Cold Mountain and "A Poem for the Blue Heron", tone is established in a multitude of ways. These two pieces of literature describe the characteristics and actions of a blue heron, both aiming for the same goal. However, Charles Frazier and Mary Oliver approach their slightly differing tones employing organization, metaphoric language, and diction.
Microevolution occurs when a species has almost insignificant genetic changes over time. The studies performed on these small genetic changes are usually tested over very short time periods (decades to a few hundred years). This is because it is difficult to find ancient DNA specimens to compare to the modern species. However, because of the frigid and preserving terrain Adelie penguins are the perfect research candidate. This specie of penguin lives, breeds, and dies all in the same location of their ancestors before them; leaving plenty of ancient remains. The researchers compared the DNA of the ancient (6,000-year-old penguins) to the modern descendants. This comparison revealed that some of the Adelie penguin genes became longer over time
Myopic little men in tuxedos, or highly efficient land/water animals? Recent research indicates there's more to penguins than meets the eye. If you've every wondered what it would be like to be able to see as clearly under water as you can on land, just ask the nearest penguin. Most aquatic animals are short-sighted on land. Most terrestrial animals (and that includes us) are far-sighted under water.
