In a given ecological setting, some species dominate and influence the abundance of the other species in that ecology. Two pathways, which lead to dominance, exist: competition where the dominance species has superior access to the limited resources and low susceptibility to other processes that are not competitive. In the second pathway, the non-dominant species are normally very susceptible to the non-competitive processes. The former pathway is highly interactive and the dominant species suppresses its subordinates by limiting the resources available to them. Sustained dominance reduces the diversity of species that ecology. The second pathway is weakly interactive and Continue reading...

Free Essay On Impact Of Climate Change On The Future Distribution Of The Earth's Principle Biome
The need for a precise forecasting of the impacts of climate change on the future distribution of the Earth's principle biome is increasing. In this paper, forecasting methods covered include: the niche-theory models which categorize species by habitat (particularly environmental conditions where species may persist or perish). The general circulation models and the species-area curve models which consider large groups of species or all species.
The existing climate models based on approximations of increasing carbon dioxide and, to some extent, by lessening sulfate aerosols, forecast that temperatures will rise by 2.5-10.4oF (1.4-5.8oC) between the year1990 and 2100. Greater warming Continue reading...

Report On Fresh Water Wetland vs Saline Wetland
A COMPARISON BETWEEN FRESH WATER WETLAND AND SALINE WETLAND
The Australian landscape has a natural component which is salt. This salt in the landscape gets into the various water bodies and affects their level of salinity which affects the way of life of the various biota inhabiting these places. Around the world and in Australia it is been identified that the salinization of fresh water is a major environmental issue. This concern of the effect of the gradual rise of salinity in water bodies’ biodiversity has resulted in the investigative studies on the lives of the invertebrate family both in the saline water and in the fresh water.

Report On A Tree Full Of Ancestors
In all three versions of the hominid family tree, there are a number of similarities. Each tree must have an evolutionary origin and purpose and whilst the origin does seem to differ from tree to tree, the purpose seems to maintain a constant: Homo Sapiens are always the end point on each tree. Presumably, this is because our species has evolved this far to date and appears to have stayed still for about 200,000 years (Human Origins) whereas another site states 175,000 years (Becoming Human), and another states 100,000 years (PBS). This dispute is Continue reading...
Free Essay On Why Evolution Is True: An Exploration
It is a shame that books like Jerry A. Conye’s best-selling book Why Evolution is True (2009) is necessary for the twenty-first century. After all, Charles Darwin wrote his groundbreaking work On the Origin of Species by Means of Natural Selection was published in 1859. Since its publication many other scientific discoveries have been made to support Darwin’s dangerous idea. Evolution should not be a controversial issue and sadly it remains so even in the most educated countries of the world. Part of the controversy could be because many people who oppose evolution have no idea what Continue reading...
Good Example Of Why Evolution Is True Essay
Evolution is the change animals and species undergo over time to adapt to certain environmental changes and eventually produce multiple descendent species. Evolution and natural selection are often taken as complimentary to each other. However, evolution, by definition, is a historical process of change, while natural selection is merely a mechanism that results in this change. Advances in technology and biology has thrown light on several causes and consequences of evolution. Some of the deepest understandings of evolution come from understanding fossils and examining phylogeny and from the study of natural selection. Evidences suggest that when natural selection is Continue reading...

The Ethics Of Small Population Conservation Biology Essay Examples
Justifications, Problems, and Solutions
The broad goal of conservation biology is, according to experts from the American Museum of Natural History, is “to conserve global biodiversity” (Calcagonotto, Egan, and Lehn 2001). Small population conservation biology is a facet of conservation biology that deals with the more specific issue of trying to preserve endangered species that have extremely low populations, and the efforts to conserve these species can be very expensive. The question of whether or not this type of conservation biology is ethically justifiable is one that can be explored by examining the approach of small population conservation biology, examining a test case Continue reading...
Good Essay On Biology: Question Answers
Habitat Destruction and Management
Question. Provide a thorough review of the patterns of habitat destruction explored in lecture.
Answer: Terrestrial habitat destruction is the result of increase in population. The main activities that cause terrestrial habitat destruction are clearing of natural plantation for agricultural activities, mining, logging and urban sprawl. Terrestrial habitat destruction has led to the extinction of rare species of organisms across the world. 50% of the world’s land (excluding Antartica) has been transformed or degraded and 50% of transformed land is used for monocultural agriculture & pasture. Aquatic ecosystem destruction is due to the pollution in the environment and water. Continue reading...
Report On Biodiversity Of Hawkesbury Institute Of Environment, University Of Western
The term biodiversity refers to the extent of variation of biological form that is living forms in terms of flora and fauna within an ecosystem, terrestrial or marine.
Generally speaking, ambient temperature and humidity are conducive to terrestrial biodiversity. If we are in a lookout for an ambient temperature and humidity, it is mainly the equatorial belt at low altitudes that comprises of highest biodiversity on land (Gaston, 2000). Similarly, in case of marine ecosystems, highest biodiversity is found in those oceanic belts which have highest surface temperatures. Accordingly, mid latitudinal region of all the oceans of the world Continue reading...
Punctuated Equilibrium: A Possible Alternative To Phyletic Gradualism Research Papers Example
Theory of evolution as proposed by Darwin has for long hinged on the fossil records to prove the process of evolution. However, the prevalent gaps in the fossils led way to the development of the punctuated equilibrium theory that was proposed by Eldredge and Gould as an alternative to Darwin’s phyletic gradualism theory. The punctuated equilibrium postulated that speciation occurs in an isolated peripheral subsect of population as a rapid change after a period of stasis. Unlike the anagenetic speciation of phyletic gradualism, punctuated equilibrium promotes the concept of cladogenetic speciation. However, punctuated equilibrium does consider rapid anagenetic Continue reading...
The Pioneer Of Biological Classification ( #2) Essays Examples
Identification of each individual from the massive inventory of living organisms requires appropriate classification system. This system allows not only identification of all specimens that are already collected, but also allows identification of the newly discovered organisms in the future. The classification system is robustly based on science and logic, so this system is universally applicable.
The classification system starts by grouping the specimens into two major categories namely animals and plants. In general, animals are grouped by the presence of appendages that implies the ability to move on their own while plants are grouped together based on the Continue reading...

Currently the distribution of tigers extends from the Pacific coast of Russia to West and Southern India, continuing East into the Malayan Peninsula and Sumatra. They inhabit a wide range of habitats from impenetrable tropical forest of Sumatra to the semi-arid tracts of Western India and the human dominated agricultural landscapes of the Gangetic Plains of India. The tiger (any sub-species) is always the top carnivore and the apex predator of any ecosystem wherever it is present. Being on top the food chain, they regulate the population of other predators, prey species (herbivores) and in turn the plant population Continue reading...
Global Warming Effects On Spring Flower Budding In Prairie Regions Research Papers Example
Spring-time events such as flowers budding have advanced by two and a half days per decade since the 1970s in Prairie regions (Korner C, Science, 2010).The flowering of a plant is a central event in its life-cycle, especially in plants growing in temperate regions of the world. These events are known as phenological changes and phenology is the study of plant and animal life-cycles in relation to annual and seasonal climate variations. Flowering phenology combines various diverse fields of study such as plant physiology, climatology, historical studies, and botany (Tooke F, J of Exp. Biology, 2010).

Population Biology Essay Example
According to Wilson and Bossert, population biology is the study of how populations of organisms change through time, essentially dealing with births, deaths, emigration, and immigration and the factors that affect these four variables (Wendell, 2012). The characteristic change in population of organisms can significantly be attributed to the competition between species that fight for scarce resources. This competition shapes the biological population and causes extinction of some species. The objective of this paper is to understand how competition between different species is important in the shaping of biological populations, including the possibility of such competition leading Continue reading...
Free Australopitheus Anamensis- The Discovery, Features And Behaviors Of Its Fossils Research Paper Sample
For a long time, Australopithecus afarensis was considered as the earliest known bipedal hominid. This made this species, which was dated to have existed around 3.5 million years ago, the oldest member of the human clan. However, the discovery of the species, Australopithecus anamensis pushed the age of the bipedal hominids further back by around 600000 years (Tomasik, 2002).

Free argumentative essay on why we must maintain biodiversity
I wanted to talk to you some more about how important biodiversity is in our lives. For example, with more genetic and population interactions we have more stable ecosystems. When we have monocultures like in farming districts the ecosystems are not stable and they are more susceptible to diseases. Biodiversity ensures a cleaner natural environment and natural barriers to floods and droughts. Animals and plant species need to interact to survive like the honey bee needs pollen from flowers to make honey. Biodiversity also protects the planet from absorbing too much heat from the sun like in tropical rainforests Continue reading...
Phylogenetic Tree Essay Example
Phylogenetic tree also known as evolutionary tree depicts the connection between various species of animals and plants based on their physical and genetic traits. Top points of the trees symbolize descendent common species whereas nodes symbolize common ancestor of descendents. Phylogenetic trees very effectively show the evolution that took place by adaptive and sudden ancestry splits. The Phylogenetic trees can be classified mainly in four types rooted tree, un-rooted tree, bifurcating tree and special tree types.

Why Is Evolution True Essay Samples
The Scientific Method is a way that Natural Scientists determine, test and prove their hypothesis. It is an organized way to prove or disprove a theory ("Scientific method," 2014).
In the context of evolution, the question to ask is: is evolution true? The next step is to do some preliminary research in order to put the question in the form of a hypothesis. To do this, the background research aims to determine if there is any empirical evidence that may support the question. The other area to explore is to question what else may have contributed to the end Continue reading...

THE SCOPES TRIAL
The scopes trial is also famously known as the scopes monkey trial and was a trial which involved the state of Tennessee against John Thomas Scopes. The charge against scopes was teaching evolution. Apparently back in 1925 it was illegal to teach anything about evolution in schools that were funded by the state. Back then people believed in the divinity of the bible. Anything in the bible was considered truth that was incontestable by any human being irrespective of the evidence at hand. Teaching evolution was tantamount to blasphemy against morally accepted truths by the people. The Buttler act Continue reading...
Good Example Of Report On Predator And Prey Dynamics
Being able to identify how predation and competition influence natural selection is essential in understanding the evolutionary ecology of a population of species. In predation, substandard individuals are inherently selected. By substandard these are the young, sick and physically unfit individuals. As a result, preys also evolve into a more resilient ones putting pressure also to the predators. This scenario reflects a coevolution of both predators and preys. In this study, we will examine the predatory-prey relationship and understand the dynamics involved in relation to environmental changes.
Four different kinds of prey and five different kinds of predator were Continue reading...
Prevalence Thesis Examples
Trichomonas gallinae, a flagellated protozoan, adversely affects the avian livestock, particularly the columbids. It causes an infection called necrotic ingluvitis and the disease can range from asymptomatic to lethal. The parasite affects the anterior gastrointestinal tract of the bird, forms granulomatous lesions, and blocks the oesophagus, making the bird starve, thus leading to death. The virulence of the strain varies with some strains causing up to 75% mortality. In UK, the infection was first recognized as an emerging infectious disease of British finches in summer of 2005. The sick dead birds exhibited signs of malaise such as lethargy and Continue reading...
Example Of Evolution And Natural Selection Essay
Evolution involves the changes to the properties of an organism that go beyond the life span of a single individual and it generally occurs as a result of either natural selection, mutation, genetic drift, or by the process of gene flow or migration. The evolution theory is regarded as one of the immense intellectual revolution in the history of the human beings and it has considerably changed the world’s view of the process of evolution. Charles Darwin is credited to have played a significant role in the development of the natural selection theory that supports evolution. As a Continue reading...

(10 pts) Provide a review of the process of succession and trends in biodiversity, productivity, and nutrient cycling.
Ecological succession refers to the process of gradual change of the ecosystems. This is attributed to the fact that habitats do not remain constant and they keep changing over time. Succession is divided into two; there is primary succession and secondary succession. Primary succession refers to changes which occur on an environment that has never been colonized before, for instance, quarrying on land that has never been quarried before. Secondary succession on the other hand involves environmental disturbance on Continue reading...
Free Report About Vegetation Richness And Diversity
Ecology, a scientific discipline based on ecosystem, interrelates organisms, vegetation, process and condition in nature. For ecological study of any landscape knowledge about structure of plant communities and role of soil is required. Knowledge of plant community is based on understanding of spatial relationships, abundance and diversity of plants or vegetation in that area. From the study of plant community and their associated edaphic or soil factors knowledge of vegetation patterns and species assemblage is developed. In a plant community it is very difficult to quantify number and distribution of all species and individuals, so techniques for obtaining representative Continue reading...
Phyletic Gradualism And Punctuated Equilibrium Essay
The inherited characteristics in a species population change over time through genetic drift, mutation, and natural selection. Natural selection was first proposed by Charles Darwin and it explains the emergence of species that are best fitted (adapted) to certain environments in which they live. The mechanism of evolution is explained by the theories of phyletic gradualism and punctuated equilibrium. In this paper, both phyletic gradualism and punctuated equilibrium are evaluated. Phyletic gradualism and punctuated equilibrium seek to explain then rate of evolution.
Gradualism is a model of evolution that suggests that speciation is a slow, constant and consistent process. Continue reading...
Example Of Resurrecting Biological Essentialism Critical Thinking
Analysis of the Article by Michael Devitt
The article by Michael Devitt is dedicated to the idea that all the Linnaean taxa have essences, which are guided intrinsic properties, which are mostly genetic. According to the biology philosophers, such theory is wrong and contradicts Darwinism, but in the article the author argues that biological generalizations drawn about the certain properties of species need structural explanation, adverting to the essential properties. In the most widespread approach, thus, the way an organism feels lie in a particular kind is ignored. As a result, Devitt shows how essentialism can integrate the Darwinism features that are associated with change and Continue reading...
