Ecological niche

The complex evolution of humans has allowed for the development of a mammal so advanced that its population has grown beyond exponentially in a relatively short time scale. The complexity of humans is due in part to intelligence in the form of a large, well-developed brain. An organ of this size and importance is what is known as an expensive tissue, meaning the body requires a substantial amount of energy to produce it (Mink et al. 1981). To explain the relationship between energy and brain…

Biotic and abiotic stresses influence plant growth and yield. The narrow layer of soil surrounding roots where essential root metabolism and activities take place is known as rhizosphere. The biology and chemistry of the soil is determined by the root excretion in rhizosphere (~1 mm broad region, has no definite edge). Hiltner was the first person to use this term rhizosphere and expressed it as the distinct zone of soil where microbial population develops due to exudation of root (Hartmann et…

microorganisms metal resistance character is regulated by genes which are organized in operons. Commonly, the heavy metal resistance genes are found on plasmid carried by metal resistant bacteria. In the presence of specific metals in the vicinity of bacterial niche the heavy metal resistance genes are expressed and induced. The regulation of expression of metal resistant gene is specific for each heavy metal and is dependent upon metal species concentration. The promoter and regulator genes of…

makes these dystopian utterances a possibility. Thus, Cormac McCarthy’s The Road (2006) showcases a post-apocalyptic world devoid of vegetation (environment) and human values that may be more immediately located in a world where global warming and ecological destruction seem to be the only logically predictable end to human civilization. Similarly, Suzanne Collins’ The Hunger Games (2008) showcases a future order where political, economic and social interests converge to promote and support…

The changes in species have been explored by many scientists, but Charles Darwin was the first to support his findings on the existence of evolution with abundant evidence. Darwin later came to develop the theory of evolution after his voyage on the HMS Beagle to South America in 1831 for five years. Darwin was an English geologist and naturalist who proposed that organisms have had physical and behavioral changes over time to increase reproductive success and to better adapt to the environment.…

Whittington’s perspective about strategy: Richard Whittington classifies strategy into four different perspectives. They are classical, processual, evolutionary and systemic: Classical theory of management, it is prevalent in the first half of the 20th century tissue introduced in the 19th century, for example, specialized in solving industrial management issues, and seeking efficiency, improve quality, reduce staff and the relationship between the cost of administration. His other…

They could also be introduced accidentally, because of increasing trade, by ocean voyaging ships, or other means. According to the National Oceanic and Atmospheric Administration (NOAA), an organism is considered an invasive species when it causes ecological and economic harm in a new environment where it is not native. Invasive species could be plants, animals, pathogens or even seeds and eggs of organisms. Invasive species…

The Alt-Right: their past, what they believe, and their future In order to begin, we should start with some historic pretext to help understand where this political group comes from. We must begin in the 1960’s. In America, there was a new movement of conservatism as a reaction to Lyndon Johnson’s great society and the new left in American politics at the time. Some of the features of this ideology are, most notably, anti- semitism, economic liberalism, and other usually far-right ideas. As a…

The Burkholderia Taxonomy and Genomics Burkholderia pseudomallei (Bp) belongs to the Burkholderia genus which contains over 40 species that inhabit a variety of ecological niches. The majority of species within this genus are non-pathogenic soil-dwelling bacteria, but a few species are highly pathogenic to humans and can result in severe disease [1]. This includes B. mallei, an obligate mammalian pathogen and the causative agent of glanders, which primarily affects horses and other solipeds…
