Ecological niche

designed to share ideas and experiences with others in a given community. Homo sapiens have distinguished themselves from the rest of the animal kingdom by incorporating complex communications into everyday life. As described in the textbook, an ecological niche is the role a species holds within its environment. Human kind has managed to defend against harsh environmental conditions, predators and cross-cultural differences using language as a means of survival. The development of language has…

for the great variety of animal and plant species observed today and that dominated the Earth surface in the past (MacDonald, 2003). In simpler terms, adaptive radiation is the diversification of species to occupy a wide range of ecological niches. The term ecological niche describes the role of a species within its surrounding environment; its interaction with the biotic and abiotic environmental factors; its survival strategies including its breeding distinctive characteristics (Cox and Moore,…

According to Heather Scoville, in evolution expert, in her article, What is a Niche? “A niche is a word that is used in ecological biology to define an organism's role in an ecosystem.” This means the place an organism lives, the organism's "job" in that environment, what an organism eats, and how it interacts with other biological and non-living species. There must be a symbiotic relationship between all species. The three main niches an organism might contend with are commensalism, predation…

Period. It is difficult for scientist to determine when the divide between therapsids and mammals occurred. Early mammals had small, mouselike forms. Very few were large, because dinosaurs were the unquestioned dominant land animals on earth. The ecological niche they inhabited included eating plants, insects, and small lizards. They lived in trees and hunted at night to avoid dinosaurs, who hunted in the daytime. They walked on four legs like mice. These mammals had the characteristics of all…

I wasn’t even considered a teenager when I was diagnosed with clinical depression. I hadn’t even understood the concept of mental disability when I began physically harming myself. All I knew was that cutting provided temporary relief from my anxieties, anxieties that I was hardly able to comprehend. A twelve-year-old is not supposed to hate themselves or be crippled by their own sadness, and yet at that time I was unscrewing the blades off pencil sharpeners anyways. For a large portion of my…

 This is the arena in which the survival of the human species is played out.  The occupants of the cultural ecological niche impose a series of selective pressures on each other as they use language and other aspects of culture to their advantage.  In general, those who have trouble learning the rudiments of language will have less chance for survival. The cultural ecological niche puts a premium on those portions of the brain associated with linguistic capability. One would expect, then,…

Although he was conscious of the stability being replaced by resistance against invaders and the concept of the ecological niche, I believe his argument loses its influence by not centralizing on how we can make invasive species become less harmful in an ecosystem with no diversity rather then completely accepting the concept that invasion decreases when biodiversity increases. He claims that niches are empty when there’s fewer species and filled when there’s more species causing ecosystems with…

Observations The several ecological factors discussed in the introduction were contrasted with the study site. The first site was analysed during high tide. Several aerate rocks occupied the rocky shore of the particular site. No presence of barnacles was noted. There were several favourable abiotic and biotic factors within this microhabitat. These included tidal action, salinity, availability of nutrients and lack of diversity within the competition of space and lack of predators. Despite…

nature of resisting antibiotic treatments, it was difficult to treat this bacterium (Sanders, 2012). Staphylococcus Aureus (S. Aureus) is one of the normal floras that make ecological niches on certain body parts but usually on the anterior nares. It is a commensal organism that can also be pathogenic if its ecological niches’ such as body’s defense system (skin, mucosal layers) is being damaged by any invasive external force where it can be introduced into the body tissues. S. Aureus forms…

Given the human and technological resources available, parents and other caretakers adapt the customs and practices of child rearing – inherited and adapted ways of nurturing, entertaining, educating, and protecting the child – to the ecological and cultural settings in which they live (Super & Harkness, 1986). The most prominent caregiving figure in Keon’s life is his Grandma Grace, a 55 year-old social worker. Although it is customary for American children to have their mothers as primary…
