The barracuda is one of about 20 species of predatory fishes in the family. Barracudas are usually found in warm‚ tropical regions‚ and they are usually associated with more shallow nearshore waters. The barracuda usually eats whatever they want. But there predators are tuna‚ dolphins‚ and certain sharks. The barracuda can protect themselves by their speed‚ size‚ and the size of their mouth. They also have camouflage ability for protection against predators. Young barracudas often hide themselves

Species: a group of organisms that can interbreed and produce fertile offspring. Habitat: the environment in which a species normally lives or the location of a living organism. Population: a group of organisms of the same species who live in the same area at the same time. Community: a group of populations living and

In the great state of Utah‚ there are many ecosystems that work together in order to create this wonderful state. Utah has many aquatic ecosystems to include: the Great Salt Lake‚ Utah Lake and the northern river otter to name a few. Utah also has the Rocky Mountains‚ which are a terrestrial type ecosystem‚ these two ecosystems are just the tip of the iceberg when it comes to Utah’s greatest areas. Utah is home to many gorgeous areas to explore‚ the focus of this paper will be on the Utah Lake

In response to this article I would have to say that it is quite an unprepared protestor unknowing of his own stupidity. He calls out the scientists fighting the overgrowth of this knotweed saying this and that‚ with reasonable arguments in my opinion‚ but then concludes with an overwhelmingly lacking solution of his own. John Stahl states‚ "I’m not sure how good knotweed will be as a paper source but it doesn’t matter." Let’s review John’s solution . John’s solution was to use knotweed as a paper

The article „ Fish in Offshore Kelp Forests Affect Recruitment to Intertidal Barnacle Populationa“ written by S.D. Gaines and J. Roughgarden is about the influence that the composition of kelp forestes has on the recruitment of barnackle. The giant kalp lives in the pacific ocean of America and its composition depends on currents‚ predators‚ herbivores and weather. To study the inshore recruitment of barnackles they took probes of the klep beds inshore and offshore and analyzed the density of plankton

Every minute‚ the world ’s human population increases by 176 people. At the beginning of this century‚ earth ’s human population already surpassed 6 billion; at the end of the century‚ it could reach 12 billion (Aliette‚ 2001). The population

1.Using Table 1‚ which of the three trials produced the highest carrying capacity for both the whales and the seals? Why do you think this trial had the best outcome for the whale and seal populations? 2.Using Table 2 and 3‚ explain how the birth rates of the seals and the death rates of the whales affected the carrying capacity for both whales and seals. 3.For the second trial in Part 1‚ we doubled the whale population and reduced the seal population by half. However‚ the carrying capacity for

Shades of Green: Measuring the Ecology of Urban Green Space in the Context of Human Health and Well-Being Anna Jorgensen and Paul H. Gobster ABSTRACT In this paper we review and analyze the recent research literature on urban green space and human health and well-being‚ with an emphasis on studies that attempt to measure biodiversity and other green space concepts relevant to urban ecological restoration. We first conduct a broad scale assessment of the literature to identify typologies of
