Genomic streamlining is a theory in evolutionary biology and microbial ecology that suggests that there is a reproductive benefit to prokaryotes having a smaller genome size with less non-coding DNA and fewer non-essential genes.
Streamlined objects and organisms, like airfoils, streamliners, cars and dolphins are often aesthetically pleasing to the eye. The Streamline Moderne style, a 1930s and 1940s offshoot of Art Deco, brought flowing lines to architecture and design of the era. The canonical example of a streamlined shape is a chicken egg with the blunt end facing ...
Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis : regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
Biogeography is a synthetic science, related to geography, biology, soil science, geology, climatology, ecology and evolution. Some fundamental concepts in biogeography include: allopatric speciation – the splitting of a species by evolution of geographically isolated populations
Evolutionary biology is the study of the evolutionary processes that have shaped the diversity of life on Earth. It incorporates genetics , ecology, biogeography, and paleontology to analyze topics including natural selection , variance, adaptation , divergence, genetic drift , and speciation .
Bioerosion is the weathering and removal of abiotic material via organic processes. [10] This can either be passive or active. Moreover, bioerosion is the chemical and or the mechanical weathering of landforms due to organic means. [3] Bioprotection is essentially the effect that organisms have on reducing the action of geomorphic processes.
The way glacial processes interact with other landscape elements, particularly hillslope and fluvial processes, is an important aspect of Plio-Pleistocene landscape evolution and its sedimentary record in many high mountain environments. Environments that have been relatively recently glaciated but are no longer may still show elevated ...
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
