plant invasions are causing profound changes to ecosystems around the world. However‚ it is difficult to generalise about their effects on ecosystem properties‚ since these vary according to the traits of the invading species‚ and the properties of the invaded vegetation and habitat. Yet‚ knowing the inherent functional traits of an exotic invasive plant could improve understanding of its invasion success and impact‚ since plant traits affect ecosystem properties such as through fall distribution‚

carnivorous fish; it will feed on any smaller fish that comes across with it. In Lake Lanao‚ the white goby is said to have an impact on one of the cyprinid species. Positive Impact: Although the white goby eat the cyprinids it does not have a large impact on the cyprinids compared to eleotrid which feeds on three endemic cyprinid species. Negative Impact: The white goby swims in fresh water. In Lake Mainit the fish was found in their fresh water container and this was the farm’s main water stock

“The Restoration of the Athenian Empire” Our walls are crumbling and our fleet is minute. We here in Athens are unable to collect tribute from other city-states and are often in threat of being attacked. Our fleet is defenseless and weak. The Democratic fraction‚ propose that we spend our time and hard earned money on the rebuilding of our walls and fleet. That way Athens can dangerously collect tributes from other Greek city-states. The Democrats also would like to commence in hazardous military

Identify the roles (producer‚ primary consumer‚ secondary consumer‚ or decomposer) of the hare and the wolf in the simulated ecosystem. Explain your answers in complete sentences. Hare: The hare is the primary consumer as it eats grass and plants. It doesn’t eat other consumers‚ making it a primary consumer. Wolf: The wolf is a secondary consumer as it continues eating/killing

Interaction between Abiotic and Biotic Components All living organisms depend upon their environment for survival essentials: 1) food 2) shelter 3) breeding site. In turn the organism interacts with the environment in several ways. For example a plant uses the environment for the three purposes named above but in turn it also removes carbon dioxide and water from the air‚ it gets eaten by an animal or a parasite and it depends on the soil for its support. Therefore the plant is interacting

Invasive species always have varying impacts on the ecosystem to which they are introduced. The introduction of the blue catfish (Ictalurus furcatus) has been treated with opposition from some due to its potential to wipe out native species‚ thus affecting the balance of the ecosystem in question. However‚ many believe that the value of the blue catfish as a sport and commercial target fish outweighs the harm done to the native populations or ecosystems. As the blue catfish is a predatory fish with

Invasive species have a very negative effect on the native species in an area. They can cause a variety of problems from competition for food resources to introducing a new disease that the native species is not immune to. Larval amphibians do not have the defenses to handle introduced predators such as fish in their environment. Therefore introducing fish into these once safe and fish-free water sources will have a huge effect on amphibian population (Wells 825). Reversal of theses introductions

grasses as well as invasive grasses. Native and Invasive species play a big role in our ecosystem. Native species make it so we don’t have to use as many fertilizers‚ use less water‚ keep the air around you cleaner‚ provide shelter and food for wildlife etc. Invasive grass species are bad because for one they are obviously not native to the area and can colonize habitats and exclude the native plants. Did you know a Dandelion is an invasive species? Well it is it from Europe but can be commonly found
