Role of Light in Ecology

Role of light is an important role in this world. As Light factor is the most essential abiotic factor without the life cannot exist. The chief natural source of light is sunlight and has great ecological significance. It plays important roles in the life of plants, such as It provides energy to maintain life on earth. It is absorbed to ...

Difference Between Terrestrial and Aquatic Ecosystems

Terrestrial ecosystems are distinguished from aquatic ecosystems. An Aquatic Ecosystem is an ecosystem in a body of water. While the community of organisms and their environment that occurs on the land masses of continents and islands are Terrestrial Ecosystem. Aquatic Ecosystems Communities of organisms that are dependent on each other and on their environment, live in aquatic ecosystems. The two ...

Ecological Causes of Adaptive Radiation

The evolution of ecological and phenotypic diversity within a rapidly multiplying lineage is called or known as adaptive radiation. It starts with a recent single ancestor. This process results in the speciation and phenotypic adaptation of species. These species exhibiting different morphological and physiological traits. Thus, they can exploit a range of divergent environments. Adaptive radiation can be graphically illustrated ...

In Vitro Methods of Germplasm Conservation

In in vitro methods of germplasm conservation, the first germplasm conservation method is the Cryopreservation. Rest of the methods are as follow: In Vitro Methods of Germplasm Conservation (a) Cryopreservation in Cryopreservation (Greek- krayos-frost) In this case the cells are preserved in the frozen state. The germplasm is stored at a very low temperature using Solid carbon dioxide (at -790C) Using low temperature deep ...

Types of Germplasm Conservation

Germplasm Conservation is sum total of all the genes present in a crop and its related species constitutes its germplasm. It is ordinarily represented by a collection of various strains and species. Germplasm provides the raw materials (= genes). The breeder uses these to develop commercial crop varieties. Therefore, germplasm is the basic indispensable ingredient of all breeding programmes. Thus, ...

Factors Affecting Soil Erosion

Factors Affecting Soil Erosion Th major factor affecting soil erosion are climate, soil properties, topography, vegetation, animals, etc. Climate Precipitation (rainfall and snowfall), wind velocity, temperature and humidity are climatic factors that affect the soil erosion. Rainfall is the most forceful factor causing soil erosion through splash and surface runoff. In terms of temperature the climate is defined as tropical, ...

Wind Erosion

Wind Erosion The removal and carrying away of soil particles b wind is wind erosion or soil blowing. It is essentially a dry weather phenomenon and is accelerated wherever the soil is loose and dry. Wind erosion mainly occurs near the ground and is influenced directly by wind velocity. Transportation of Soil Particles The soil transportation is caused by three ...

Water Erosion Control

Mechanical Methods of Water Erosion Control Mechanical protection against soil erosion is expensive, time consuming and deserve careful thought and planning. However, it plays a very vital role in controlling and preventing soil erosion on agricultural lands. They are adopted to supplement biological methods. The mechanical measures include diversions, terraces, bunding, sub-soiling, basin listing and waterways. Diversion Drains A diversion ...

Control of Water Erosion

Control of Water Erosion Water erosion can be minimized by preventing the detachment and the transport of soil particles. A cover of vegetation and soil granulation helps to prevent the detachment of soil particles. The transportation of soil particles can be effectively minimized by artificial mechanical structures to control the effects of runoff. Biological Methods of Water Erosion Control Control ...

Soil Erosion Types

Soil Erosion Methods of Control and Conservation Erosion literally means weathering away. It refers to “removal of fertile soil surfaces from their original place and carrying away by agencies such as wind, water, ice or gravity to some other places”. The erosion consists of detachment of soil particles from the surface and transportation. Water and wind are the major factors ...
