Ecotone & Edge Effect by Suvasree Sahu
What is Ecotone? An ecotone refers to a transition zone or boundary between two different ecosystems or biomes. It is a region where distinct ecological communities come into contact, mixing and interacting with each other. Ecotones are characterized by unique environmental conditions and species composition, resulting from the merging of the features of the adjacent ecosystems. Due to the blend of ecological conditions, ecotones often exhibit higher species diversity and increased biological productivity compared to the adjacent ecosystems. They can act as critical habitats for various wildlife species, offering resources and opportunities for feeding, breeding, and shelter.
Continue Ecotones can be found in various natural landscapes, such as the meeting point between a forest and grassland, the shoreline where land meets water (e.g., a coastal wetland), or the boundary between a desert and a savanna. These transition zones are essential for maintaining biodiversity, as they facilitate species migration, gene flow, and ecological resilience in the face of environmental changes. However, ecotones can also be sensitive to disturbances and may be more vulnerable to the impacts of human activities and climate change. Proper conservation and management of ecotones are crucial for sustaining healthy ecosystems and promoting ecological balance.
What is Edge Effect? The edge effect is a phenomenon that occurs in ecotones, the transitional areas between two distinct ecosystems. It refers to the unique conditions and ecological dynamics that arise at the boundary of these ecosystems. The edge effect is characterized by a variety of ecological changes that differ from those found in the interior of each ecosystem.
Elongation During this stage, the ribosome moves along the mRNA in a 5' to 3' direction, reading each codon in succession. The appropriate tRNA molecules bring the corresponding amino acids to the ribosome, where they are linked together to form a growing polypeptide chain. Peptide bonds are formed between adjacent amino acids, and the ribosome moves to the next codon, repeating the process.
