The Negative Effects Of Invasive Species In The Galaapagos Islands

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

An introduced species is a species that were intentionally or accidentally transported to another area in consequence of human activities such as planes, ships, heavy water pulling it away from its natural environment. These organisms do also commence becoming invasive after they are shipped on purpose to be supplied as exotic pets, decoration, food for livestock or humans, or way to eradicate native `pests.

The poop of the Galapagos Penguin fertilizes the land allowing for the healthy growth of plants which are consumed by other animals that live on the islands. If the Galapagos Penguin became extinct, it could possibly cause the extermination of local plants such as the “Ulva” leading to the extinction of the animals which rely on them. These include the “Parrot Fish”, Sally Lightfoot Crabs, “Five-Spotted Anthia” as well as many more species of land and sea

Invasive species make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

The Galapagos Islands consists of thirteen major islands and over a hundred smaller islands located along the Ecuadorian coast. The islands are home to a variety of unique species such as sea lions, sharks, rays, and 26 different species of native birds. Thirteen of these birds are Darwin’s finches. These finches are known to be the “world’s fastest-evolving vertebrates” due to their bodies quickly adapting to the rapidly changing environment (Robertson, N.D. , para.1). Their DNA chemical makeup causes these adaptations to occur. The finch’s most noticeable feature is their evolutionary adaptations, due to the briskly changing environments.

The world is under attack; by aliens from our own planet. These aliens are known as invasive species. Government agencies such as the Environmental Protection Agency (EPA) and the Department of Natural Resources (DNR) have identified invasive species as living organisms that are not native to an ecosystem and their introduction can cause harm to the environment, infrastructure, and people. When these creatures are in their natural ecosystem they can be held in check by predators and other organisms that have evolved to deal with them. Without these opponents invasive species can and will cause economic and biological damage to the area they are introduced to. Invasive species can affect anyone and anything and they must

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.

When someone introduces an non-native species into a new environment, it could harm its surroundings. Also known as an invasive species. The definition of an invasive species is “1) are not native to, yet can spread into, wildland ecosystems, and that

An invasive species is a plant, fungus, or animal species that is not native to a specific location and one point should be noticed is that invasive species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake because they compete with native cutthroat trout for habitat. Although there are some invasive species arrive with spread and establish populations, like the native butterflies feed on non-native plants in California, the alien trees help restore abandoned pastures to a condition suitable for native plants in Puerto Rico and even the much-maligned zebra mussel helps filter toxins from great lakes, most policymakers regard invasive

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.

Invasive species are organisms that are not native to an ecosystem and cause harm to it. These organisms are capable of bringing about a great deal of damage to the ecosystems they are foreign to. This can range from disrupting the growth of the environment it has taken over to completely decimating other species. The introduction of invasive species to new environments often involves humans. The way that invasive species are introduced to a new environment varies greatly. Invasive species may be introduced by something as simple as humans accidentally tracking species into a new environment from the bottom of their shoes, or something bigger like destroying an ecosystem to clear the land, forcing the species that lived there to flee to a new ecosystem that can be disrupted by the presence of a new species.

While on the Galápagos Islands, Darwin kept notebooks about all the species there, and he noticed the variety of tortoises on the island who were essential in explaining his theory of evolution. There are several species of tortoise present on the Galápagos Islands that are all very closely related, but slightly different. There are eleven presently surviving subspecies of Galápagos tortoises; furthermore, six of the eleven are found on different islands in the archipelago, and the other five are all found on a single island on five separate volcanoes with their own mini-ecosystems (PNAS). Although all of the species of Galápagos tortoise is different, they each have small differences that can include maximum adult size, shell shape, and the length of the neck and limbs. The tortoises of the islands are most closely related to the Chaco tortoises along the western coast of South America, and they most likely came to the Galápagos by “rafting” across the water (PNAS). Similar to the tortoises, Darwin observed that the Finches on the islands also had changed to match the environment. Spread among the islands were fourteen subspecies of finch whose
