70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.
They create a well balanced ecosystem by being the prey of amphibians and small water insects and eating algae found in ponds and lakes. When there is not Daphnia present in lakes and ponds, an increase of algae and decrease of fish can be seen. Because of their sensitivity to the surroundings and its transparent carcass, when Daphnia are in hypoxic conditions, more hemoglobin is produced and they appear red. Hypoxic is when the body or part of the body is lacking adequate oxygen supply. This red color can be seen about
Natural selection is the process by which evolution occurs where organisms that are better suited to the environment (‘fittest’) survive and pass on favorable traits to the offspring. Organisms must adapt to the environment in order to survive. The stickleback fish adapted to the environment by keeping/removing the pelvic structures. For example, in Frog Lake, the all of the sticklebacks had complete pelvic structures because the lake was connected to a system of streams that allowed predators into the lake. The sticklebacks in Bear Paw Lake had reduced or absent pelvic structures because little/no predators are present in the lake.
Throughout the story of “The Red Dragon and the White Dragon” by David Day, symbolism is used to show how the White Dragon represents the Saxons and how the Red Dragon represents the Britons. To explain, as Day retells the story of how the two dragons were discovered; he mentions that Merlin elaborates on the dragons’ fight. He retells that Merlin stated, “[the red dragon’s] dwelling place shall soon be occupied by the White Dragon, who is the Saxons you have welcomed into your kingdom.” Moveover, the White Dragon, as a symbol, is used to warn the Britons that the Saxons, who they have let into their country, are a dangerous threat. Thus, they are warned that the Saxons are harsh opponents that will defeat them in battle.
The dragon represents the demise of Beowulf's kingdom, the end of a happy and peaceful era for the people. Overall, Beowulf has many twist and turns, but most of all symbolism.
An interesting feature of this lake is that it contains no large mouth predators of the fish. Normally, the spines of the fish keep them protected from these predators, but here in Bear Paw Lake, the spines actually decrease the fitness of the fish because the dragonfly larvae living at the lake bottom prey on the fish by grabbing them by their spines. Due to natural selection, eventually the fish in the lake population lost their spines on the undersides of their bodies.1 The fish that had low fitness due to their spines were killed and unable to produce offspring while those without spines or maybe with reduced spines lived long enough to
(Shmoop) To be fair, this dragon is terrifying. As described by Grendel, “Vast, red-golden, huge tail coiled, limbs sprawled over his treasure-hoard, eyes not fiery but cold as the memory of family deaths... The color of his sharp scales darkened and brightened as the dragon inhaled and exhaled slowly, drawing new air across his vast internal furnace; his razorsharp tusks gleamed and glinted as if they, too, like the mountain beneath him, were formed of precious stones and metals.” (Gardner 57)

After the underwater type of dragon came onto land the species of dragons branched out into a bunch of different kinds of
In Christian mythology, long ago there lived a dragon in the province of Libya who terrorized the citizens of a nearby town. He stole their maidens and breathed his poisonous breath for twenty-four years. He resided in “a pond like a sea” ( de Voragine Web), with skin harder than brass. In Norse mythology, there was another dragon, or sea serpent, named Jormungand, who was so large his coils wrapped around the

According to Hodgkinson et al, there are “disparities in poverty rates depending on age, race or ethnicity, family structure, and geographic location. Although the largest number of poor and low income children are white, minority children are disproportionately affected, particularly African American, American Indian, and Hispanic children. In 2013, Hispanic and African American children were ~3 times more likely than white and Asian children to be poor. Children raised by single parents and children raised in the South or West are also more likely to be poor or low income than children residing in the Northeast” (Hodgkinson et al, 2016). Children and youth are a vulnerable population because they have no control over their situation or environment;
If a man could dream about something mythical it would be dragons. Dragons are one of the famous mythical creatures that people have dreamed about, they have tried to prove their existence, came up with theories but it was nothing but just a hoax. However there is a dragon that lives in the ocean, it does not breath fire, nor lives in a cave. But rather swims in the ocean with it’s dangerous venom for its protection against other species and humans. The Blue Dragon has an extraordinary shape, with a specific domain and an incredible diet.
Often considered one of the greatest American writers of the twentieth century, F. Scott Fitzgerald rose to fame as a young, decadent writer who captured the essence of wild economic prosperity and cultural pleasures of the 1920’s known as the Jazz Age. His works are heavily influenced by his everyday life that was plagued by effusive relationships and vicarious self-indulgence. His time spent at Princeton University and in the Army, marriage to eccentric socialite Zelda, and long-time battle with alcoholism all contributed to the vigorous nature of his novels and short stories. Fitzgerald’s life ended relatively early and in far from the spry state of its beginning. Fitzgerald entered Princeton University in September of 1913, contributing to many university publications with his early short stories and humor columns.
