In order for populations to evolve in response to natural selection, they must be large enough that natural selection is a stronger evolutionary force than genetic drift. Recent studies on the impacts of habitat fragmentation on adaptation in some plant species have suggested that organisms in fragmented landscapes may be able to adapt to ...
Environmental issues in Myanmar include air pollution, water pollution, deforestation, and issues relating to climate change. Myanmar is a country with a high percentage of forest covering and is said to have the most forest cover remaining in a Southeast Asia country. At the same time, it also has a rapid deforestation rate of over 2 percent ...
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is ...
Example for a nature-based solution in the area of water resource management: this riparian buffer protects a creek in Iowa, United States from the impact of adjacent land uses Nature-based solutions (or nature-based systems , and abbreviated as NBS or NbS ) describe the development and use of nature (biodiversity) and natural processes to ...
Air pollution is also a major contributor to surface water pollution. The type of pollutants in the air emitted by industrial facilities, motor vehicles, and agricultural bio-waste released to the atmosphere affect the quality of marine and fresh water bodies, thus affecting marine life, plants, animals, and ultimately human survival.
Marine plastic pollution. The pathway by which plastics enters the world's oceans. Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish ...
e. On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) [3] is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. It was published on 24 November 1859. [4]
Industrial melanism is an evolutionary effect prominent in several arthropods, where dark pigmentation ( melanism) has evolved in an environment affected by industrial pollution, including sulphur dioxide gas and dark soot deposits. Sulphur dioxide kills lichens, leaving tree bark bare where in clean areas it is boldly patterned, while soot ...
