Ecological Succession The world around us is slowly and constantly changing. We might never see the small alterations happen, but many years later changes will surely be visible. Over time small changes add up and soon the whole ecosystem is different. This slow change in the land and habitat is called ecological succession. Animals, plants, and weather are some factors that cause this type of change in an ecosystem. Ecological succession begins with a pioneer community. In many cases lichens are

Intermediate Disturbance Hypothesis Background Habitats and the ecological communities they support are often greatly impacted by disturbance. For example, forest communities can be disrupted by fires, blow-downs, floods, and hurricanes. Alpine plant communities can be devastated by landslides or avalanches. Marine systems such as coral reefs can be decimated by storms, ravaged by predators, or trashed by inconsiderate tourists. On a smaller scale, many habitats can be disturbed both above

Age and EWT 1. Describe the aims, procedures, findings and conclusions of Poole and Lindsay’s (2001) study of the effects of age on EWT – science demonstration Aims- The aims of their experiment were to assess whether children were able to source monitor. Procedures- They used child participants aged 3-8 years of age. They were shown a science demonstration throughout the day; later that day their parents read them a story, which contained aspects of the science demonstration. The next day

The ecological validity of both papers should be considered similar as they both employ the same methodology. Studies on the MNS provide inconsistent results, a systematic review by Hamilton (2013) found that of twenty-five studies on the MNS found twelve studies supporting a normal MNS, six studies suggesting an abnormal system and seven studies with mixed results. The use of studies from six different methods including EEG and fMRIs, found that every method provided results both supporting the

Mutiple Baseline Across Behaviors The case study I have chosen is Mrs. Davis, which used a multiple baseline across behavior design. Steve has a number of behavior issues that interfere with his and his classmates learning. One of the weaknesses in multiple baseline across behavior design is being able to attaining functional similarity and independence among the target behavior. Especially trying to establish functional similarity before intervention. The problem I see with the design

Sustainable tourism is one of the pre-requisites of achieving sustainable development. the concept of tourism with sustainability and development gets its historical inclusion from mass tourism that got flourished in 1960s due to advent of jet aircraft and the passions for tourism got tremendous following and it also reached Third World countries (Dann, 2002). It was also argued that this boost pushed organizations like World Bank and UN to examine the cost benefit analysis of tourism and it

and higher incomes should mean better choices, richer lives, and an improved quality of life for us all. However, the banking crisis of 2008 forced us to confront our inability to manage the financial sustainability of the global economy and the ecological sustainability as well. In addition, led the world to the brink of financial disaster and shook the dominant economic model based on economic growth to its foundations. The aim of this report is to define sustainable economy in terms of six themes:

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts: * the concept of needs, in particular the essential needs of the world's poor, to which overriding priority should be given; and * The idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs."
