Discussion and evaluation
Station:1
Bird count
As seen in the results of the bird count we will notice that as some bird species are at a stable and increasing population, others are decreasing. These are due to factors such as:
1)Climate
2)Different species and their co-existence
3)Human involvement
4)Food and break down of the ecosystem
These points shall be briefly discussed below.
Climate plays a very important role for most species. Like us humans we are accustom to a specific weather type, we can adapt but we don’t enjoy it. Birds such as Red Knobbed Coot also enjoy a different climate and they may have left Intaka Island, due to the climate change; by means of pollution in the atmosphere or just a change in season as it may destroy their food source or even nest/habitat. Therefore it is vital to keep the use of any pollutants away from our atmosphere as it can damage/change our climate.
Birds are critically involved with the whole ecosystem/different species, as we may be with our community and neighbors. If one gets ill or dies it has a huge impact on our lives, the same as the birds as it may be their source of food or nest; this may damage the ecosystem by ways of human involvement(pollution/litter/noise/poaching) and natural causes. This may also effect the birds as they may have an enemy during their existence, that either eats them for energy or destroy/inhabits their nest.
The Essay on How Climate Change Affects Human Health
Over the last 50 years, human activities – particularly the burning of fossil fuels – have released sufficient quantities of carbon dioxide and other greenhouse gases to trap additional heat in the lower atmosphere and affect the global climate. In the last 100 years, the world has warmed by approximately 0.75°C. Over the last 25 years, the rate of global warming has accelerated, at over 0.18°C ...
Our very presence on earth may also effect the results, due to our common and daily pollution and life movement. We as humans pollute a lot, though not always intentionally. We do this through ways of development(sound, water and air pollution) to just plain old littering. This whole process destroys the bird’s stable ecosystem and therefore forces the birds’ to move and live somewhere else.
The food and destruction of the bird’s ecosystem, not only effects them but other species as well. This is due to the fact that now the animal above the food chain will not receive an energy source, which will have a ripple effect on the rest of the food chain/web. This also damages our humanly lives, by means of tourism and source of food and pets.
Now that these points are discussed we, see that these might impact certain bird species and results. Therefore I say in order to receive accurate results, repeat the experiment over a year period, once or twice a month for all 12 months.
Station:2
Plant diversity/quadrant count
During the Intaka Island field and experimental trip, we were meant to preform a plant count, in groups and each group had their own species of plants. It shall therefore be discussed, to see why each quadrant has those specific species of plant. This shall all be explained with the following factors:
1)Plant growth
-Nutrient supply
-Water
-Oxygen
-Temperature
-Sunlight
2)External factors
-Disease and biological factors
3)Plant formation
-climate
-landscape
4)Others
Now in order for plants to grow in a certain area, they need certain nutrients, temperatures, pH and nitrate levels from water and a certain amount of CO2 gas. If any one of these factors, fall away the plant cannot grow in that particular area. So if the land in which you want to plant a plant, is low in nutrients high in temperature and pH and low on CO2, the chances are that the plant will not grow; due to that plant not being exposed to high nutrients and CO2 in order to photosynthesis(produce food for energy).Just as we need food to preform our tasks. Temperatures will be influenced in climate and just as birds, a plant needs great temperature to feel comfortable and not dry out. The pH and nitrate levels of the soil/water are also important as the plant may be quite selective over a base, with low nitrate levels compared to the opposite. This is like buying a house in which you don’t like because its small. Now for sunlight, which is also used to help plants photosynthesis, and some plants may need a balance, a low or a high amount of light to preform this function. In conclusion to this part we see that plants are extremely selective in order to grow/survive.
The Term Paper on Factors Influencing Older People's Food Choices
The older peoples’ food choices may be influenced by a number of Physiological, Psychological, Social and Economic factors. Lets look at some of these factors and why they affect the elderly food choices. Physiological factors: People who choose food because of physiological factors are usually because of: Hunger, Appetite or Satiety: Hunger is your body’s way of telling you that you ...
External factors that can influence plant population and growth is due to disease spread and other species. When another specie has a disease, it may be able to spread not just to other species but water, soil and other objects. This disease may harm the whole ecosystem and damage plant life and the wood web. So, we must maintain each plant and specie as well, to ensure plant survival. Other biological factors such as animals may overgraze upon a specific plant, therefor damaging the food web and ecosystem. This therefore indicates that the results may be effected by disease or overgrazing of plants in an area.
Plants also require a foothold/infrastructure to maintain growth and survival of those plants, in that area. Such infrastructure includes: landscape and climate. If these are not made that plant cannot grow or survive in that area, therefore it might effect results.
So the results collected may have been effected by the following above discussion. Therefore I say in order to receive accurate results, repeat the experiment over a year period, once or twice a month for all 12 months.
Station:3
Soil Profile
While at Intaka Island for the experimental trip we, evaluated 2 soil samples in recorded them as results. We shall now look at what factors shall influence the results and discuss them. The factors are:
1)Soil formation
-Parent material
-climate
-landscape
-Time
-Biological factors
2)Soil once formed
-pH
-nitrates
The Essay on Wild Animal Animals Species Life
Chris Mahoney Enviornmental Studies INST. Stead Spring 3 MIDTERM 1. ) How exactly would you distinguish Jonathan Swift's 'Modest Proposal' and modern factory farming of veal, cows, chickens, and pigs? What are the relevant similarities, if any? Relevant differences? There are many different viewpoints for why it is wrong to torture and slaughter animals for the needs and purpose of humans. Animals ...
-what this does as a whole to the wetlands
Soil has many factors in which it requires to form, the very first is the parent materials. These are in the landscape, such as rocks under and above ground these rocks were first moved via wind/water and then withered. The landscape refers to the land in which the soil is place, forest or woodlands etc. It also refers to terrain formation. Landscape will effect the moisture of the soil. Climate also has a deep impact on moisture and texture on all soil. If cool it will provide moist soil, if hot it will provide dry soil. Time shall refer to as age of the soil and how much stuff biodegraded in it. The more degradation the more moist and better the water retention and texture. This though can only be possible through species of plants and animals and other biological factors/species. These factors will help us determine if the soil is but correct in place of a wetland.
Once the soil has formed we see that in order for it to support life its pH and nitrate levels have to support it. If the nitrate and pH levels are to high, it shall support more acidic life, great for wetlands. If opposite it supports more alkali life, not good for wetlands. So if the soil is correctly leveled for wetland life the the base for life on the wetland is correct and perfect.
So the results collected may have been effected by the following above discussion. Therefore I say in order to receive accurate results, repeat the experiment over a year period, once or twice a month for all 12 months.
