community has adapted to live in a slightly different zone on the rocky shore, in order to avoid competition as much as possible. This is an example of Gause's principle; that no two species can have to same ecological niche, as one will always be better adapted, and soon wipe out the other. If there were, for example, to be a flood, then the high-tide organisms (such as the Brown-Barnacle and Blue-Banded-Periwinkle) could end up exposed to more wave action than they would usually experience as high-tide organisms. This wave action could pull them off the rocks, killing them, or the water would restrict their oxygen intake and they could drown. They would experience environmental factor levels they are not adapted to, exceeding their tolerance level, causing them to undergo physiological stress, and eventually perishing. This would cause many populations to decrease in size. The zonation pattern would be disrupted, and the community pattern may disappear altogether. However, the community pattern will return with time. This is because succession is taking place, as organisms replace each other and fall into their allocated niche in the community. The disrupted area has fewer species, with fewer defined zones as the different species have not had time to move into their different niches. Eventually we would expect the regenerating rocky shore community to return to the state it was before the disruption.…
The evidence that corroborates competition is that the percentages were 57% and 58% which dictates that competition can explain cohabitation. Furthermore the competitive exclusion hypothesis states that no two species can occupy the same niche and coexist. In figure one, we can see that PcMix was starting to diminish because it cannot inhabit the same niche and would have continued to decrease until extinction. The niche structured is made up of resource continuum which leads to resource…
Bio 2.3 Ecological niche Three species that I studied 1.)Dolphin 2.)Great White Shark 3.)Emperor Penguin Animals need gas exchange for one main reason and that is to survive , all organisms need this gas exchange process to burn glucose for fuel which is a simple but important energy source that is a component of many carbohydrates. The respiratory system is where there is a series of organs taking in oxygen and getting rid of carbon…
survivorship; which death known is known to be greatest among the young. But in our ecosystem; type I survivorship are known to be typically exhibited by humans and elephants. But type III survivorship is known to be typically exhibited by many fish species. However, type II survivorship is known to be relatively rare in nature (For example, only a few species of lizards are known to be exhibited in this type of survivorship). 8. What is an ecological niche? In all ecosystems, an ecological…
In the western United States forest succession and the role of fire as a mechanism triggering forest community succession and the interaction of drought and forest fires are significant to the ecosystems and the living animals and plants affected by it. Forest succession is the replacement of new life in plant or animals in a forest. Fire is a mechanism triggering forest community succession because it is a disturbance to the community; it destroys all the trees and living organisms in that…
In the fast developing world, there is no room for doubt that rapid economic development is one of the most successful achievements in human history,both in developing countries and developed countries. Countless people are sharing the improvement of living standard in many aspects. However, with the threat posed by the increasing environmental problems and resource shortage problems, considerable amount of public attention is being attracted to the achievement of sustainable development.…
general area of body dissatisfaction and media images has its limitations too. According to Sparks (2013), Alan Roberts and Emily Good reported that the harmful effects of media images might not be as widespread as what we used to believe. In fact, recent research suggested that the harmful effects of media exposure to thin body images seemed to happen mainly for women who are high in neuroticism. This implies that the majority of women would not be affected by media exposure to thin body…
The idea of an all-natural or “green home” is seen The Living House, which discusses how South East Asians build their homes out of the local plant material (Waterson 1990: 74). I am doing the same with my house as the use of the local material allows the natural ecosystem around the habitat to remain the same and uninterrupted. The floor will be made of Sitka spruce tone wood from the surrounding vegetation. This wood will only be harvested from already fallen trees instead of trees cut down…
In her groundbreaking work, “Trace,” Lauret Savoy argues that land and regional social norms are deeply intertwined with the past. Within a conception of Nature that is predominantly ecological and anthropocentric, Savoy’s contention that racial minorities and people of mixed heritage are disposed to feelings of alienation and struggles of identity, because of a long history of cultural erasure and suppression, is undeniably valid. She revises Alexander Cronon’s argument, in his work “Uncommon…
This study is based on conceptual framework from Donabedian (1966) McCkorkle et al. 2011. Mitchel, Ferketish and Jennings (1998) state: Donabedian 's perspective was essentially linear, assuming that structures affect processes, which in turn affect outcomes. Patient characteristics are sometimes considered as mediating outcomes and clinical interventions are considered to be processes” (Mitchel, Ferketish and Jennings, 1998). Per Grove, Burns and Gray (2013), the Design of this study is a…
