Short Summary Essay On Biodiversity

In contrast some plant species which are considered as invasive plants are still using in many forest management practises. So it is important to investigate whether they are really invasive, or whether they really negatively impact on ecosystem and to understand what are their impacts on ecosystem, in order to have a

2. Biological differences between human beings reflect both hereditary factors and the influence of natural and social environments. In most cases, these differences are due to the interaction of both. The degree to which environment or heredity affects any trait varies greatly. 3.

ENP provides plants and animals with the resources that they need. The park provides many habitats where flora and fauna thrive, such as sawgrass prairies, freshwater sloughs, pine rocklands, estuaries, and hardwood hammocks. These habitats have been altered by many factors including human impacts, hurricanes, non-native species, water quality issues, water quantity issues, wildland fires, etc. (“Environmental Factors”). These factors are the main culprits that are causing the degradation of the park.

Duration, severity and rate of imposed stress are the factors underlying the plant response to stress (Munné-Bosch and Alegre, 2004; Omezzine et al., 2014). Under natural conditions, Plants and surrounding environment as well as their neighboring plants can interfere together during seed germination and seedling growth causing various morphological, physiological and biochemical responses (Tanveer and Rehman, 2010; Shanker and Venkateswarlu, 2011; Harun et al., 2014). However, plants, including weeds, grow in the same community are competing for moisture, nutrients, and light, they can also affect a neighboring crop growth and yield by releasing allelochemicals into the growing environment (Rice, 1984; Kim and Shin, 1998; Kadioglu et al., 2005; Tanveer and Rehman, 2010). Such plants, that negatively impact other plants through the production of secondary metabolites, are considered allelopathic. Wheat (Triticum sativum L.) and pea (Pisum sativum) are of the most ancient crops known to man.

For example, it can help predict things, different changes in habitats, applied to many problems, and help understand the different effects on a habitat. However, there are some limitations when dealing with IBT. For example, habitat fragmentation. When it comes to habitat fragmentation, there are somethings that cannot be controlled and having something that separates two habitats, like an ocean or body of water can really limit activity of the different species, and limit how they interact with their habitats. Other limitations would be improperly managed habitats, harsh conditions, or human interactions.

Fusarium spp. : A large number of Fusarium spp. are present in soil, often occupying a saprophytic role from where susceptible host tissue may be attacked. Fusarium avenaceum, F. culmorum, F. oxysporum and F.solani are the more important species involved in diseases of seedlings and cuttings. These species are generally not host specific at the seedling stage and have a wide host range.

Historically, terrestrial habitats used to be in rigid environments, lacking in organic matter and nutrients and were not favourable to plants with primitive root system. AM fungi were important for the successful invasion of plants onto land. Fungi, with their nutrient scavenging hyphae, were able to obtain nutrient better. Today’s terrestrial ecosystem are more favourable to plant invasion, but AM fungi remain to be involved in the ecosystem processes which are the the Carbon and Phosphorus cycles. The part of AM fungi in ecosystem is obvious, but the implication of AM fungi biodiversity on ecosystem-level measures is less arguable (Heijden & Sanders,

Invasive plants can be in the form of trees, shrubs, vines, grasses and flowers and they are difficult to control, however they can be controlled with the implementation of a biocontrol agent, which decreases the spread of the said species. A biocontrol agent is the use of an organism to control the presence of another. These organisms can be in the form of insects or grazing animals, and although it can limit the negative effects of the invasive plant by controlling its growth and its negative impacts, such

As human beings we come to this world with a certain characteristic or nature that lays a foundation for the environment to work on as we are growing up. As human beings, throughout life we are exposed to different things in our environment, and our nature starts to change as a result of trying to adapt to the environment. Hence, my argument that nurture having a bigger impact on behavior than nature comes from an evolutionary idea of environmental selection. Evolution tells us that every organism faces environmental pressure or a selection pressure, and in order to survive organisms need to be able to adapt. An individual even though born with a certain nature, will most probably have a change in nature at some point in their life time due to environmental pressures.

The ethical question posed by pitting urban sprawl vs. biodiversity hinges on what one considers to be in the best long-term interest of the world as a whole. There are a number of perspectives that can affect this consideration.
