3/1/17 Topic and Country: Ecosystems in Botswana Purpose: To inform my audience about ecosystems in Botswana. Thesis: Botswana ecosystems are very unique and diverse. They have many different types of animals, plants life, and climate. Introduction Attention Getter: If I went somewhere in Africa, I would go to Botswana. I would go to Botswana because they have a very unique country. The country has many different types of not only animals, but plants, and climate.  An ecosystem is a group of plants

underpinnings: Ecosystem Services Valuation Framework The study will be guided by the ecosystem valuation framework (Hein et al., 2006) to quantify and map a range of ecosystem services and evaluate the impact of land use change on these ecosystem services (provisioning, regulating and cultural services). The ecosystem valuation framework is applicable to all ecosystems and very valuable in modified (semi-natural and natural) ecosystems. The framework categorize valuation of ecosystem services into

If the amount of grass is reduced in the ecosystem, the entire food chain will be affected greatly. Due to a smaller food source, the primary consumers, the savanna hares, will also experience a decrease in population since the new amount of grass can not sustain the initial amount of savanna hares. Since the savanna hare population decreases, the food source for the secondary consumers, the caracals, will also experience a decrease in population. The caracals do feed off of other animals, but it

change may be one of the greatest threats to our modern day life and the future of our planet. Climate singlehandedly is able to impact natural resources, vegetation, and human impacts on an area which and effectively destroy the functionality of an ecosystem. Many climate change deniers use the formal definition of climate to support the idea that climate change and global warming does not exist - they believe that climate is simply the natural changes in weather over time. However, the change we have

What is an invasive species? Invasive species is any animal or plant that comes from a different ecosystem and causes harm to the environment. They are called “invasive” because they reproduce quickly and spread rapidly, causing destruction on people’s health and the ecosystem. Human activities are one of the biggest contributing factors in spreading invasive species from one location to another. People can purchase these invasive plants for their beauty, low maintenance, and fast growing nature

invasion has been underway that has continued to endanger much of Americas ecosystems. To call a species “non-native” or “invasive” does not sound too threatening, but the truth is they are one of the primary threats to native wildlife in an area. An invasive species can be any kind of living organism—an amphibian, mammal, plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs—that is not native to an ecosystem and which causes harm to the environment, the economy or even, human health

tree feeding parasites. This is important as many different species of Mistletoe interact with environments differently, some acting as keystone species helping the environment thrive with diversity; and some are detrimental killing the trees and ecosystems. In order to better understand how to deal with different types of populations depending on the

Due to that spiders have played a beneficial role as being the predators within the food chain. On the other side, spiders are also the prey for other organisms. In either positions spiders do play a role in the ecosystem; their risk of endangerment also risks the stability of our ecosystem. Overall, spiders have a significance in our ecological community. Spiders are predators of insects and other spiders. Due to their diet of eating insects and pests that destroy farms they help farmers in their

AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them. Explain why we should care about protecting

Introduction of Foreign Species into the Australian Ecosystem B1. Investigate the impact of human activities on the diversity of living things. Describe the impact that this activity has on the environment and species diversity. The early European settlers of Australia during the Imperialism introduced feral animals into Australia for many different reasons without knowing the harmful effects it brings to the ecosystem of their new home. For example, rabbits were introduced in 1859 by English explorers

All over the globe, vulnerable ecosystems are in a fight against invasive species. These invaders threaten global biodiversity and negatively impact ecological systems. They tend to tip the natural balance and wreak havoc on native species, disrupting the vital interactions of endemic flora and fauna and putting human health and economies at risk. Island ecosystems are particularly vulnerable; as they are often hotspots of biodiversity found nowhere else on the planet. Removing these invaders as

Also, even if they tried to renew their resources, the demand rate was increasing so much, they would have never been able to save the ecosystem. “While the hauhau tree did not become extinct in Polynesian times, its numbers declined drastically until there weren’t enough left to make ropes from” as stated in Easter’s End. Another similarity was that most of the species in these environments

72580 Rodriguez Silva The Top-down Effects of Brine Shrimp on Algae INTRODUCTION An ecosystem is a delicate structure moderated by the network of interactions between all of the organisms that inhabit it. These organisms can be arranged into trophic levels, forming a chain or pyramid in which energy flows from one level to another. In a top-down trophic cascade, the higher-leveled consumers regulate and dictate the biomass of the trophic levels below (Leroux and Loreau 2015). The removal or addition

& Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species

Biodiversity Biodiversity is the variety of all living organisms in a specific habitat, it is made up with abiotic and biotic factors. Biodiversity gets used to measure the health in a ecosystem. Humans have, over several years, created threats to biodiversity, one of them is overexploitation. Under the impact of biodiversity changes and overfishing by humans, many species have become extinct, which, in the end influences the biodiversity again. Many solutions have been attempted to be created over

Changes in the ecosystem can occur at any time and can have many different outcomes. In paragraph 17, Darwin tells us about one of his explorations to find the meaning of the struggle for existence he came across something that could serve as great example. He came across a field near Farnham, located in the United Kingdom, where he observed a land that had been enclosed to keep out cattle and allow the Scotch firs to grow without getting eaten or stepped on by any of the animals. Darwin uses another

Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats. They were first introduced to the Great lakes in 1988 but were originally from Russian

other aquatic ecosystems and ecological complexes they are part of. they include the diversity within species, between species and ecosystems. Biodiversity also refers to the abundance of different species living within a given region. It showcases the wealth of biological resources available to us. It sustains the natural area that is comprised of animals, plants and other living things. Why biodiversity is important It is the founding block of most of the vast array of ecosystem services that

Savanna Description/definition Savanna is characterized by rough grasses, it can also be considered as a rolling grassland with scattered tree growth normally where the margins of the tropics where the rainfall is seasonal which is eastern Africa. There are many kinds of savannas that are on either side of the equator. There are some savannas found in Australia and South America. Climate and Location Savanna’s climate is typically warm temperature all year round. As odd as it might sound Savanna

The amazon rainforest is home to various different kinds of species ecosystems that work equally separate and together to perform their roles that are vital to humans and wildlife that have adapted to its uses and benefits. The interlinking web of ecosystems and creates a unique biological richness that cannot be compared across the globe which is an accurate representation of how truly magnificent and important the Amazon is. Because the climate is not the same across the world, biodiversity is
