query: where do exotic species tend to cause the most problems?

pos: Frequently Asked Question About Invasive Species An invasive species is an exotic species whose introduction into an ecosystem in which the species is not native causes or is likely to cause environmental or economic harm or harm to human health. It is important to note that when we talk about a species being invasive, we are talking about ecosystem or environmental boundaries, not political ones.

neg: Areas with Prevalence of Fleas and Ticks Areas with Prevalence of Fleas and Ticks. Fleas and ticks pose more of a problem for dogs and cats in certain parts of the United States than in others. A climate where the environment is warmer and more humid allows populations of fleas and ticks to explode, causing serious health concerns for the cats, dogs, and humans in these locations.

neg: - Environmental Impacts. The introduction of invasive species can result in the extinction of local species and irreparable changes to the habitat and biodiversity of invaded ecosystems (Chornesky and Randall 2003). The Convention on Biological Diversity lists invasive species as one of the direct drivers of biodiversity loss (CBD 2007).

neg: - Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it might not have any natural predators or controls. It can breed and spread quickly, taking over an area.

neg: Habitat Loss of habitat is the single greatest threat to any species. If an island on which an endemic organism lives becomes uninhabitable for some reason, the species will become extinct. Any type of habitat surrounded by a different habitat is in a similar situation to an island.

neg: What is an Invasive Species? When an invasive species is much more abundant than a native relative, they may hybridize so often that the invaders genes flood the native species, such that no individuals contain the entire genotype of the native species, thus effectively driving the native species to extinction.

neg: - Habitat destruction, alteration and fragmentation are probably the most serious causes of current and future amphibian population declines and species extinctions (Dodd and Smith 2003). Amphibians are found in a great variety of ecosystems from tropical rainforests to arid deserts (Stebbins and Cohen 1995).

neg: - Typically found in domesticated animals, there are more than 100 species of babesia, and a few have been found to afflict humans, in whom it can produce malaria-like symptoms such as fevers, chills, and headaches.

A rkansas is no less prone to invasions by animals, plants and diseases than coastal states. In addition to natural dispersal, invasive species arrive in the state by trade through air, rail, highways and waterways. Many invaders are easily overlooked until they are plentiful enough to cause economic or human harm. Managing invasive species has several approaches, depending on the

neg: - Survey results indicate Minnesota boaters are more knowledgeable about exotic species issues and have already changed their behavior to a greater extent (to prevent the spread of exotics) than boaters in the other two states (figure 1). FIGURE 1.This suggests that educational programs are effective.n order to determine if boaters perceived exotic species as a threat to their lakes and streams, they were asked to rank a variety of possible threats. Only in Minnesota did exotic species rank among the top three concerns.

neg: What Are Invasive Species? In the United States, economists estimate that more than $120 billion are lost annually to damages associated with invasive species. Invasive species threaten native plants and animals and their habitat in forests, marshes, and other natural areas. Learn more about invasive species that threaten Virginia here >>

neg: - Examples of introduced species. The plants and animals that have been introduced into Australia have caused major problems in the ecosystem. Among these are rabbits, feral pigs, cane toads, European carp, camels, snails, starlings, Paterson's curse, thistle, foxes and cats.

neg: - Invasive species often compete so successfully in new ecosystems that they displace native species and disrupt important ecosystem processes. Plants, fish, insects, mammals, birds, and diseases all can be invasive.

For the past two decades, the. biologist has searched dense jungles and snow-covered forests in an effort to track down and study large carnivores--animals that are often at risk of extinction.

neg: Why insect pests love monocultures, and how plant diversity could change that The Problem With Monocultures . The problem with monocultures, Wetzel said, is that if an insect likes the crop, that insect has a large food supply to draw from all in one place. Conversely, a field containing a variety of plants does not offer a large block of food for the insect, so it will not get the nutrients it needs to survive and thrive.

neg: - But these invaders, large and small, have devastating effects on U.S. wildlife. Invasive species are one of the leading threats to native wildlife. Approximately 42% of Threatened or Endangered species are at risk primarily due to invasive species. Human health and economies are also at risk from invasive species.The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.uman health and economies are also at risk from invasive species.

neg: Malaria Prevention of malaria may be more cost-effective than treatment of the disease in the long run, but the initial costs required are out of reach of many of the world's poorest people. There is a wide difference in the costs of control (i.e. maintenance of low endemicity) and elimination programs between countries.alaria parasites belong to the genus Plasmodium (phylum Apicomplexa). In humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi. Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%).

query: why is ph important in water

pos: The Importance of pH in Wastewater Treatment The pH of water can be used to kill off bacteria in wastewater in addition to the treatment mentioned above. Most organic matter and bacteria we are familiar with and contact daily are best suited to a neutral or slightly basic environment.

neg: pH The pH of the water will determine the toxic effects, if any, of these substances. For example, 4 mg/l of iron would not present a toxic effect at a pH of 4.8. However, as little as 0.9 mg/l of iron at a pH of 5.5 can cause fish to die. Synergy has special significance when considering water and wastewater treatment. The steps involved in water and wastewater treatment require specific pH levels.

neg: What does pH in water mean? pH basically tells you of the concentration of hydronium ions in water. Basically pH is the negative exponent of the concentration in water. For example pure water has pH of 7. Some water molecules (H2O become hydroxide OH-and hydronium H3O+) ions. pure water has 10^-7 moles of hydronium ions per liter of water.

neg: How to Maintain the Proper Pool pH Level Why the pH Level Matters. If your pH level is too high, the water is too alkaline and will begin to cause the formation of scale on various surfaces within the pool and equipment. If your pH level is too low, it is acidic. This will cause corrosion on surfaces in your pool and on your pool equipment.

Solutions with a pH below 7.0 are considered acids.

neg: pH pH is a measure of the acidic or basic (alkaline) nature of a solution. The concentration of the hydrogen ion [H+] activity in a solution determines the pH.Mathematically this is expressed as: pH = - log [H+]. The pH value is the negative power to which 10 must be raised to equal the hydrogen ion concentration.or example, 4 mg/l of iron would not present a toxic effect at a pH of 4.8.

Solutions with a pH below 7.0 are considered acids. Solutions with a pH above 7.0, up to 14.0 are considered bases. All organisms are subject to the amount of acidity of stream water and function best within a given range. The pH scale is logarithmic, so every one-unit change in pH actually represents a ten-fold change in acidity.

neg: The pH of Water A water with a pH > 8.5 could indicate that the water is hard. Hard water does not pose a health risk, but can cause aesthetic problems. These problems include: Formation of a scale or precipitate on piping and fixtures causing water pressures and interior diameter of piping to decrease;

neg: - Waters with low alkalinity are very susceptible to changes in pH. Waters with high alkalinity are able to resist major shifts in pH. As increasing amounts of acid are added to a water body, the pH of the water decreases, and the buffering capacity of the water is consumed.evels of 20-200 mg/L are typical of fresh water. A total alkalinity level of 100-200 mg/L will stabilize the pH level in a stream.

neg: Limestone and Acid Rain One important buffer in surface waters is the carbon dioxide/bicarbonate/carbonate buffer. When water is in equilibrium with both CO2 form the atmosphere and carbonate containing rock, the pH of the water is buffered to a pH of 8.3, close to the pKa of the weak acid bicarbonate HCO3- (pKa = 8.4). The buffered water resists changes to pH from additional acid or base.

neg: Water Chemistry Total Alkalinity. Alkalinity is a measurement of the alkaline materials dissolved in water. In the ideal range of 100 to 150ppm, alkalinity helps the pH to resist fluctuations. If the alkalinity is low, it can cause a “pH bounce” — meaning the pH level fluctuates in and out of the acceptable range.

neg: pH -- Water properties The pH of water determines the solubility (amount that can be dissolved in the water) and biological availability (amount that can be utilized by aquatic life) of chemical constituents such as nutrients (phosphorus, nitrogen, and carbon) and heavy metals (lead, copper, cadmium, etc.).ne of the most popular school science projects is to take the pH of water from different sources. Chances are your school (and certainly not you) does not have an electronic pH meter lying around, but you can still get an estimate of pH by using litmus paper.

neg: pH of Water The acidity of the surrounding environment can also affect the pH of water. This is most obvious near mining areas, but the effect can also occur naturally. Acid runoff depletes the water’s alkalinity and lowers pH below optimum levels. This may be tolerable for some aquatic species (such as frogs) but not for most fish.

If the pH strays too far above or below 7.0 water becomes corrosive and will begin to eat away at anything it touches.

neg: Basic Water Chemistry Part 1: Water Hardness Well water from areas which have a lot of limestone (calcium) is often hard. Water that comes from lakes and rainwater is often devoid of minerals, making it soft. It is important to understand how water hardness affects pH in your aquarium. Hard water (high mineral content) is usually high in pH. Soft water (low mineral) is usually low in pH. The mineral in hard water acts as a buffer that combats aridification in the water. The resulting water will be more alkaline and higher in pH.

neg: - The ideal pH range for water is between 7.2 and 7.6. This means that the water is slightly basic. By maintaining the proper alkalinity of water, the pH will stay around the ideal levels. However, if the alkalin-ity gets too low, the pH can start to deviate and can begin to cause water quality problems.lkalinity of water is due to the presence of certain ions: carbonates, bicarbonates, and hydroxides (often referred to as alkaline salts). Bicarbonates are the most common cause of alkalinity and are found in almost all natural water sources, as are carbonates.

neg: pH of Water However, changes in pH can also affect alkalinity levels (as pH lowers, the buffering capacity of water lowers as well) ⁶. pH and alkalinity are directly related when water is at 100% air saturation ⁹. The alkalinity of water also plays an important role in daily pH levels.

neg: - The alkalinity of water is a measure of how much acid it can neutralize. If any changes are made to the water that could raise or lower the pH value, alkalinity acts as a buffer, protecting the water and its life forms from sudden shifts in pH.

Solutions that have a pH less than 7 are referred to as acidic and solutions having a pH greater than 7 are alkaline. Pure water has a pH that is close to 7. Since alkaline water has a pH level that is higher than tap water, there are plenty of proponents who make the claims you have read in this article.

neg: - pH is a measure of the amount of Hydrogen ions (H+) in a solution. Ions are just atoms that have an electric charge on them, so H+ is a hydrogen atom with charge of 1. Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions).
