Because all organisms and ecosystems are subjected to a multiplicity of influences, it can be difficult to predict the ecological effects of changes in environmental conditions.

Some environmental influences are resources that organisms can exploit as opportunities, which allows them to gain the necessities of life and livelihood. Other environmental influences are stressors, or constraints on productivity and reproductive success. Many stressors operate in a continuous chronic fashion, as is often the case for climatic factors, soil and water pollution, and many biological interactions.

Other stressors affect organisms and ecosystems as events of disturbance, which cause severe damage in a short period of time. A disturbance is followed by an extended period of ecological recovery called succession. Disturbance may be caused by natural forces such as a wildfire or windstorm, or by anthropogenic influences such as the clear-cutting of a forest or ploughing of a field.

Ecology considers the structure and function of the web of life at a hierarchy of levels:. Each of these levels of ecology is meaningful, and all are relevant to environmental science.

However, these various tiers of ecology are not totally discrete—they are all interconnected and each level influences every other. This chapter examines issues that are relevant to the various hierarchical levels of ecology. Coral reefs are shallow-water ecosystems in tropical seas, and they are extremely rich in species, as is illustrated by this community near Puerto Morelos, Mexico. Source: A. Autecology is the field within ecology that deals with the study of individuals, populations, and species.

Important topics in autecology include the following:. Each species is unique and can be described by its anatomical, behavioural, biochemical, and ecological attributes. These characteristics are ultimately determined by the collective genetic variation that exists among the individuals that comprise the species. Each species is unique.

Nevertheless, species can be aggregated into groups based on similarities of their attributes. These affinities may be due to ancestral relatedness, due to related species sharing aspects of their evolutionary history.Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.

Ecologists study these relationships among organisms and habitats of many different sizes, ranging from the study of microscopic bacteria growing in a fish tank, to the complex interactions between the thousands of plant, animal, and other communities found in a desert.

Ecologists also study many kinds of environments. For example, ecologists may study microbes living in the soil under your feet or animals and plants in a rain forest or the ocean. The many specialties within ecology, such as marine, vegetation, and statistical ecology, provide us with information to better understand the world around us.

This information also can help us improve our environment, manage our natural resources, and protect human health. The following examples illustrate just a few of the ways that ecological knowledge has positively influenced our lives. Some non-native species plants, animals, microbes, and fungi not originally from a given area threaten our forests, croplands, lakes, and other ecosystems.

Introduced species, such as the kudzu vine shown here, do this by competing with plants and animals that were originally there, often damaging the environment in the process. For example, the gypsy moth, a native of Europe and Asia, wreaks havoc on great swaths of forest lands by defoliating, or eating the leaves off of trees.

At first, highly toxic chemicals, which also poisoned other animals, were the only methods available to control this introduced pest. Wetland clean up site at Ft. McHenry, Baltimore. Ecologists have discovered that marshes and wetlands filter toxins and other impurities from water. Communities can reap the benefit of this ecological service. Leaving some of these filtering ecosystems intact can reduce the burden on water treatment plants that have been built to perform the same service.

By using natural filtering systems, we have the option to build fewer new treatment plants. Ecologists have discovered that many plants and animals produce chemicals that protect them from predators and diseases. Some of these same chemicals have been synthesized by scientists or harvested from the organism and used to treat human diseases. For example, the Pacific Yew tree produces a substance which is used in cancer treatments.

Another example is a substance found in horseshoe crabs, hemolymph, that is used in leukemia treatments. An adult deer tick Ixodes scapularis sits on a leaf. Black-masked member of the weasel family once occurred in central grasslands and basins from southern Canada to Texas but is now one of the most endangered mammals in North America.

An ecosystem is any geographic area that includes all of the organisms and nonliving parts of their physical environment. An ecosystem can be a natural wilderness area, a suburban lake or forest, or a heavily used area such as a city.

The more natural an ecosystem is, the more ecosystem services it provides.

These include cleansing the water wetlands and marshes and air forestspollinating crops and other important plants insects, birds, batsand absorbing and detoxifying pollutants soils and plants. Short for biological diversity, biodiversity is the range of variation found among microorganisms, plants, fungi, and animals.

Some of this variation is found within species, such as differences in shapes and colors of the flowers of a single species of plants. Biodiversity also includes the richness of species of living organisms on earth.

There is an interdependence that ensures the survival of organisms based on the connections between them. Some types of interactions involve feeding, reproduction, disease transfer, and cycling of nutrients. Models can involve building something to scale, predicting patterns using computer simulations or using mathematical algorithms.

They help ecologists understand interactions and ecological systems better. It is the part of the earth that extends from the deepest depths of the ocean to about 6 miles into the lower atmosphere. Water biomes are distinguished by salinity and water movement. Land biomes are characterized by temperature and precipitation. Organisms from all 6 kingdoms are included and abiotic factors such as light, moisture, pH, gasses and minerals are present in varying amounts. Size does not distinguish one from the other.

An ecosystem can be as small as a fallen tree and a community can be the forest. A population in its strictest sense is defined as a group of individuals that are the same species which can interbreed and live in the same place at the same time. This includes plants, animals, dead organisms, and the waste products of organisms. Abiotic factors are environmental factors that are not associated with the activities of living organisms which includes air, water, rocks, and temperature.

For example, if the temperature or water level goes above or below a certain level then their chances of survival go down. A tolerance curve is a graph designed to show this range. This is something that happens during the lifetime of an organism and is not a genetic change that gets passed on to the next generation.

Organisms that cannot regulate internal processes and are controlled by these changes are called conformers. Organisms that can use energy to control internal conditions within a range of tolerable environmental conditions are called regulators. Burrowing or hiding underground to escape heat or predators.
