The Intermediate Disturbance Hypothesis By Observing Plant Diversity Patterns Along A Trail

Luckily, humans have put in efforts to understand and sometimes reverse the damage done. Wilcove describes ecosystem restoration, where usually humans put concentrated effort into recreating original habitats to restore indigenous populations. This is, unless “a very different assemblage of species has taken hold of the land and cannot be dislodged,” also known as a new “steady state” (Wilcove, 2000, p. 12). Wilcove himself joined the effort by studying the impacts humans have caused on woodland critters. He surveyed an area in Maryland to detect predators by setting cardboard coated in masonry powder to record footprints. He concluded that there were “six predators: opossum, raccoon, striped skunk, dog, cat, and blue jay. All are animals that benefit mightily from their association with people”(Wilcove, 2000, p. 42). He also mentions how extensive data can only be collected when looking at the observations of many people over the generations. He talks about “generational blindness,” which means how observers of a current generation cannot make conclusions on populations without the help of data collected from the past (Wilcove, 2000, p. 13).

In contrast to the upheaval of animals in a development area, humans also make efforts to preserve biodiversity and forests by creating wild life

When going to the sand dunes of the Illinois Beach State Park, we wanted to test the effects of different environment on succession, ecosystem development. The problem was to find out if there is a succession (ecosystem development) of plant communities taking place. If the sand dune’s closer to the lake are newer than those further inland, then, I believe succession will take place because the newest dunes do not have rich enough soil to support more complex plants like trees and shrubs growing in the areas that have already gone through later stage succession. The data supported our hypothesis.

The purpose of this experiment is to observe secondary succession at Umass Dartmouth and test the prediction that diversity increases through ecological succession. Students went outside to the lawn underneath the wind mill on campus. 3 transect sites were located by the instructor. Students predicted the species and percent cover of each species on each trail site. Bar charts were made to compare the number of species in each transect. Pi-charts were made to compare the percent coverage of species in each transect.

The annual rate of precipitation, and elevational range once generated a strong foundation for a wide diversity of vegetation

Since organisms living in communities form interdependent relationships, a change in the abundance of one species will not only affect the physical and more direct interactions, but could indirectly affect the number of other species within the community as a consequence (Wootton 1993). These indirect affects rise because the interactions between pairs of species are not independent of other species, such as increasing the density of vegetation may increase the survival rate of the prey, reducing the intensity of the interaction between the predator and prey (Wootton 1993, 1994). An

Biodiversity boots ecosystem productivity where every little species plays an important role in maintaining a healthy community. Maintaining a viable habitat requires lots of efforts, determination and frequency. Invasive plants are a major threat to our natural environment. These invasions change the natural diversity and balance of ecological communities. They threaten the survival of many plants and animals. They are excellent at surviving and reproducing which out-compete the native plants. Understanding these huge consequences let us understand why volunteer activities like this are so helpful and needed. They play a huge part in contributing to our environment in many positive ways. Removing these invasive plants are helping a lot in restoring the habitat and giving native plants greater chance for survival. As time went by, these efforts will slowly help cleaning our atmosphere, providing our environment with fresh air and improve health effects in human (Sagoff,

It examines the how browsers can encourage positive conditions for temperate forest soils, such as providing extra nitrogen in the soils as a fertilizer. They found evidence that deer populations promote plant species biodiversity because it promotes invasive species that thrive off of degradation and habitat disturbance. Also, researchers found one cost about deer browsing was that even though it promotes plant biodiversity, it also decrease the amount of palatable, or edible, plant species. This is useful in my paper because it provides a different outlook of the effects of deer because most articles are negative towards deer browsing. The authors of this paper all work for the United States Department of Agriculture Forest Service as research ecologists, all have their doctorates in ecology and/or biology. This finding sharply contrasts with the negative impact that deer have when their populations kill and over browse, harming native plant

I boarded the Amtrak the early morning of November 5th, 2016 from Davis, California to the Peytonia Slough Ecological Reserve (Peytonia Reserve) in Suisun, California. The trip to this brackish and saltwater reserve was to help me analyze the relationship between humans and wildlife in urban settings. Urban environments depend on the rehabilitation and protection of small natural areas like the Peytonia Reserve. At the Peytonia Reserve, both humans and native/non-native species live in cohabitation, which paints an accurate representation of reconciliation ecology. Humans use these natural areas, the Peytonia Reserve in this case, for recreational activities like hunting and fishing. This, in turn, benefits the wildlife that lives in the area because hunters and fishers want the environment to be well maintained in order to support their activities. I came up with the conclusion that even though humans have more to benefit from wildlife, wildlife also depends on humans to help protect and conserve their habitats.

First, the reading passage poists that the Yellowstone fire caused termendus damage to the park's trees and other vegitation. The professor contradicts this notion by stating that the scorched area was a suitable place for emergence of new plants which were unable to grow before the Yellowstone fire. Thus, according to the professors claims, this area will have more diversy vegitation than before the Yellowstone fire.

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be

The health of the earth degrades with the destructive activity of human beings. A recent study by a group of scientists looked at twenty four different services that the earth’s ecosystems provide for humans, ecosystem services, and found that fifteen of them are in need of desperate help (Gazette 31 March 2005). These services are vital to the survival of both human and nonhuman life and include filtering water and providing nutrient rich soils and ocean waters. Many of the members of these various ecosystems are also decreasing in numbers. In a British survey of bird populations found that in the 200 birds of Britain tracked there was about a 54% population decrease between the 1968-1971 tacking period and the 1988-1991 tacking period. In two other surveys of 254 native plant species from the same area there was a decrease of about 28% during the past 40 years. Humans are pushing the sixth mass extinction (Gazette March 19, 2004).

This study explores the concept of whether native vegetation fosters the presence of native birds and/or non-native vegetation fosters the presence of non-native birds. My working hypothesis is: “there is no difference in the percentage of native and non-native birds between “gardens” having native or non-native vegetation.” Note: the word “garden” for the purposes of
