O. Wilson, John Muir, Aldo Leopold, Gifford Pinchot Q.an area in need of restoration has been all or partly damaged, degraded, or transformed from ________________. - ANSWER-human activities and natural disasters Q.Which of the following is an example of a successful restoration project? - ANSWER-putting up silt fences, planting vegetation, and creating sediment ponds to counter act erosion from a flood Q.Less damaged ecosystems do not require periodic monitoring after restoration completion - ANSWER-False Q.Restoration and protection of keystone species should be a priority because doing so always protects the other species in a community. - ANSWER-False Q.A(n) _________________ is a species that has a disproportionate effect on its environment relative to its abundance. - ANSWER-keystone species Q.Which of the following is an example of both interspecific and intraspecific relations between organisms? - ANSWER-Competition Q.Which of the following scenarios might be explained by Gause's law of competitive exclusion? - ANSWER-Variation in beak size of finch species observed by Darwin Q.There is generally less energy present in the autotrophs present in a food web than in the heterotrophs. - ANSWER-False Q.A population is a group of plant or animal species which cohabit within a geographic area. - ANSWER-False Q.Some plants, such as legumes, are able to transform _____________ from the air into compounds that can be used by the plants for growth. - ANSWER-Nitrogen Q.An organism's realized niche is generally larger than its fundamental niche. - ANSWER-False Q.The following diagram represents the relative importance of each species (x axis) within a community. Which graph best represents the distribution of importance illustrated by the keystone species concept? - ANSWER-A Q.West Virginia University has successfully restored forest on abandoned pasture throughout the state. To accomplish this, the same process is always used: till the pasture, plant with native tree saplings protected by deer fencing, followed by an annual mowing of the field up to year five. Thus far, they have achieved 100% success rate. This is an example of what type of community assembly rules? - ANSWER-Deterministic community assembly rules Q.There is a theoretical chain of islands in the Indian Ocean that are a recent result (geologically- speaking) of volcanic activity. Although all of these islands are within the same archipelago, they are all subject to similiar degrees of atmospheric and human influence. However, the flora and fauna of these islands vary considerably. Which one of the following terms would NOT describe a function or process that likely took place on the islands. - ANSWER-Deterministic community assembly rules Q.Ecosystem goods and services are the product of ecosystem processes and functions. - ANSWER-True Q.A brownfield is being considered as a restoration project; however contaminants remain in the soil that prevent the growth of nitrogen-promoting plants. Without the growth of nitrogen-promoting plants, it is highly unlikely the historic plant community will ever become re-established. The contaminants are an example of: - ANSWER-Abiotic filters Q.The idea behind constraints and filters is similar to niche theory, in that constraints and filters are species specific. - ANSWER-True Q.Natural disturbances cause less impairment to an ecosystem that human-induced impairment. - ANSWER-False Q.Succession is the term we use to describe a set of recognizable and repeatable combinations and temporal sequences that govern the formation of ecosystems and communities. - ANSWER-False Q.A polluted wetland has been restored following restorative action by the state. Which of the following is an example of an ecosystem service provided by this improved wetland? - ANSWER-increase water cleansing capacity
