The consensus model of criminal justice is a theoretical approach that emphasizes the role of social and cultural factors in shaping criminal behavior and the administration of justice. This model contends that crime is not the result of individual pathological or deviant behavior, but rather a product of social and economic inequalities and the ways in which the criminal justice system responds to these issues.
One of the key tenets of the consensus model is the idea that crime is a social construct, rather than an objective reality. This means that what is considered criminal behavior is not necessarily inherent to the act itself, but rather is defined by the values and norms of the society in which it occurs. For example, certain behaviors that may be considered criminal in one culture may be completely acceptable in another.
The consensus model also emphasizes the role of social and economic inequality in driving criminal behavior. Studies have shown that individuals who come from disadvantaged backgrounds, such as poverty or racial discrimination, are more likely to engage in criminal activity. This is often due to a lack of access to resources and opportunities that would allow them to succeed in mainstream society.
The consensus model also focuses on the role of the criminal justice system in responding to crime. According to this model, the system should aim to rehabilitate offenders and address the root causes of crime, rather than simply punishing offenders. This approach is often seen as more effective in reducing recidivism and promoting public safety in the long run.
One of the key criticisms of the consensus model is that it may be too idealistic and fail to take into account the reality of crime and the need for punishment. Some argue that certain types of criminal behavior, such as violent or predatory offenses, require harsher punishment in order to deter future crimes and protect the public.
Overall, the consensus model of criminal justice offers a valuable perspective on the complex factors that shape criminal behavior and the ways in which the justice system responds to it. While it may not be the only approach to addressing crime, it offers an important perspective on the need to consider the social and cultural context in which crime occurs and to seek more effective and rehabilitative approaches to addressing it.
Ecological Succession: Concept, Process and Its Strategies
A climax community will persist in a given location until a disturbance occurs. Marram grass is a xerophyte that is adapted to live in harsh environments. Simple species that can tolerate the often harsh environment become established first. Successful computer simulations of some temperate forest successions have been made using data for invasion, growth, and death of individual trees. This occurrence of a relatively different sequence of the community over some time in the same area is known as ecological succession. The term particularly refers to habitat changes brought about by the biota, as when soil is built and nutrients collected.

On the whole a population can thus be controlled by invoking any or all the seven ways of death: i Starvation outright energy deficiency: food, calories or light ; ii Malnutrition lack of nutrients or water or essential components ; iii Predation; iv Parasitic diseases; v Accident probably weather-induced ; vi Failure to be born; and vii Failure to find a mate. Example: Autogenic succession can be seen in the facilitation type of succession mechanism. Photo of a chaparral ecosystem the winter after a fire For example, the seeds of a native chaparral wildflower, called whispering bells, require smoke exposure to germinate. The sizes, frequencies, and intensities of disturbances differ among ecosystems, creating differences in what is called the In Molothrus ater is particularly frequent in ecotones between mature forests and earlier successional patches. Dianne features science as well as writing topics on her website, jdiannedotson. Thus the species composition maintains equilibrium. Small plants slowly colonize the rubble field left behind by a retreating glacier.
Process of Ecological Succession Natural succession occurs through several stages and processes. Succession that occurs after a significant geological event, like a glacier retreat or volcanic eruption, is called primary succession. Either factor is indicative both of the rate of population turnover and of the intensity of environmental resistance. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. The progressive invasions of perennial herbs, shrubs and trees are by species whose life-history phenomena are of progressively longer life, with all the diversion of resources from reproduction to storage and defence that these life histories-demand.
This is it for Mechanisms of succession. Process of Ecological Succession : Succession has the appearance of a cooperative enterprise. This island is devoid of terrestrial plants and animals initially, but then the island will be colonised rapidly by migrants arriving from across the sea. It is self-perpetuating and in equilibrium with the physical habitat. But the hypothesis predicts that the pioneers will certainly be displaced as k- strategists invade the site from surrounding complex communities. The importance of these various ways of death vanes widely with different life-history strategies, producing quite different patterns of population control. Example: Allelopathy: Some plants secrete chemicals to make the soil less suitable for germination and growth of invasive species.
The animals found during this stage include nematodes, insect larvae, ants, spiders, mites, etc. Halophyte: Salt tolerant plants that grow in places of high salinity, for example in swamps, marshes and seashores. The initial sere was known as Pioneer seral stage. This process continues and successive communities develop one after another over the period at the same area until the final community again becomes more or less stable for some time. The ecosystem is now back to a similar state to where it began.
Within the next few years, grasses and perennial plants return to the area. Microscopic organisms, like protists, colonize the area first. Birth rates vary in some species, actually being kept low by patterns of behaviour that work to regulate births according to supplies of resources. Distinction is made between true parasites, social parasites, and parasitoids. Larger plants that are better adapted to grow in deeper soil can store more water and therefore grow faster.

Organism colonization happens differently in each succession type due to variations in ecological conditions after a disturbance. What is a climax community ecological succession? Sea water began corroding the exposed metal almost as soon as the Coolidge sank, and sea life started to disintegrate the ship. It may take hundreds or thousands of years for the ecosystem to approach its original state. At first, only a few species can exist; as time goes by and changes occur in the environment, many more species can occupy the region because the environmental conditions have become favorable for them. There are also some animal pioneer species.
After soil is created by the mosses and lichens, grasses and small plants begin to colonize and dominate the habitat. However, the chaparral shrubs can re-sprout from their root crowns, so it only takes them a few years to re-establish themselves as the dominant vegetation. Co-actions may either be beneficial to the participants, cooperation, or harmful to them. Shade-tolerant species eventually outcompete plants with greater sunlight requirements. Because primary succession starts from scratch, it often takes longer to complete than secondary succession. However, studying succession can also provide valuable insights for ecologists and wildlife managers interested in restoring those natural systems: through careful management such as controlled burning or invasive species control, people can help ecological communities stay strong. In many regions, secondary succession occurs where wildfires have destroyed conifer forests, or where former agricultural land is reverting to meadow or scrubland.
The result is a life history distinctly different from that of opportunist or fugitive species. Which among the following is the correct sequence in ecological succession? Human activities often prevent climax communities from forming. Both are possible, of course, but their appearance cannot affect our general explanation. The hypothesis that succession is the predictable replacement of r-strategists by k-strategists is readily convincing for all seral stages up to forest. What is ecological succession and its types? Each plant community creates conditions that subsequently allow different plant communities to thrive. So soft corals were among the first species — called pioneer species — to take hold on the wreck. The soil in chaparral ecosystems is very poor and often very rocky.
