Indicator Species

Indicator Species

Indicator species, organism—often a microorganism or a plant—that serves as a measure of the environmental conditions that exist in a given locale. Indicator species are chosen for their sensitivity to environmental conditions. Example of indicator species such as:
·         Plants, algae, mosses, and fungi
-      The presence of certain species of plants suggests how well other species might grow in the same place.
-          Mosses often indicate acid soil.

-          Greasewood indicates saline soil

-          In Vancouver, Canada, the environmental health of estuaries is monitored by the indicator species of eel grass.
-      Lichens, which are a combination of an alga and a fungus growing together, are indicators of air pollution, especially sulfur dioxide, a waste product of burning sulfur-containing fossil fuels. In Great Britain, bushy lichens grow only in clean air. Leafy lichens tolerate some air pollution and crusty lichens can survive with higher levels of pollutants. If no lichens are present, it usually indicates heavy air pollution.

-        Tubifex worms indicate oxygen-poor and stagnant water unfit to drink.


-          Amphibians, Adult frogs and toads live on land and in water and are good indicator species since the skin of the adults is moist and permeable, allowing numerous pollutants entry into their bodies. Tadpoles live in water and indicate water quality issues.
-          Amphibians make good indicator species because we live in two environments, land and water, and have thin skin that we sometimes breathe through. Our thin skin can also absorb toxic chemicals, radiation, and diseases. If there are lots of frogs and other amphibians in a habitat, it means the ecosystem is healthy.

Fish
Salmon are an indicator species for wetland ecosystems of Greater Vancouver as well as over the greater Pacific Rim. The National Wildlife Federation lists them as species at risk due to pollution, river channelization, dams, deforestation and urban sprawl. Commercial farmed salmon increase the chance that accidental interbreeding occurs and that diseases could spread into wild populations.

    Nice ais, mungkin bisa ditambahkan penjelasan mengapa lumut dijadikan indikator tanah yang asam ?

Tolerance range

Tolerance Range in biology refers to the specifications of environment in which particular species can survive. These environmental factors include temperature, humidity, salinity, quality of soil and quality of air. Tolerance range differs from one species to another. Factors included in tolerance range differ too. For plants, crucial environmental conditions include sunlight and minerals in soil, whereas for animals temperature and quality of air are important. For both plants and animal, a certain amount of nutrients must be available to them to consume in order to survive. Range of tolerance also varies within a given population, from individual to individual, and across a life cycle of one individual. If living organisms find themselves within their range tolerance, they can maintain homeostasis, meaning the internal conditions necessary for carrying out their life functions. The optimum range is the mid-point on the scale of tolerance range, where most individuals in a popul

Limiting Factors

• Condition is abiotic environmental factor that varies in space and time and affects the performance of organism. Example is temperature can affect the reproduction of organism because to matting and lay the egg, need a warm temperature. • Resource is all things consumed (used up) by organisms (space, nutrients, water, prey, holes for refuge, etc) and its can devided into  Interactive resources. An organism does not need certain resources independently. For example, one that gets more heat might need more water, or less nitrogen.  Non-interactive resources. Independent resources that an organism needs. For example, a human being needs both iron and calcium, though ingesting one will not affect the need for the other. Liebig’s law of the minimum: Growth of a plant is dependent on the amount of foodstuff which is presented to it in minimum quantity. This law of the minimum was first expressed by Justus Liebig in 1840. This law of the minimum is less applicable under ‘transien

Ectoterm dan Endoterm

Ectothermic animals Ectothermic animals are animals that are very dependent on the temperature in the external environment to increase its body temperature due to the heat generated from the whole system of metabolism only slightly. Ektoterm animals, a group of animals whose body heat depending on the heat from the outside of the body, namely the environment. Power regulator for temperature is very limited and its body temperature varies with the temperature of the environment. This causes poikilotherm animals have a low tolerance range, in the sense that this animal narrow niche subject. When the ambient temperature is high, beyond the limits tolerance, ektoterm animals will die while when the ambient temperature is lower than the optimum temperature, activity was low and the animal becomes very slow, making it easy for predators to catch. Power set in animals ektoterm and not of physiological adaptation but rather in the form of behavioral adaptation. For example, moves to the sha
