Introduced species

organisms results in invasive species, yet, officially, invasive species are classified as any organism who poses a threat to the environment (Invasive Species). Consequences of invasive species include the destruction of ecosystems and the deterioration of the quality…

When looking at the data provided, the trends of native-species increase in the restored area and the abundance of exotic species seen in the degraded areas provides an idea of how effective the restoration efforts where at restoring them to the reference site. To begin, the data provided in table 5 gives an idea of the distribution of the number of species found at each site, and how much of a contrast is shown between the restored and degraded areas and how they compare to the reference site.…

The Euwallacea was studied before, but observers were incorrect in identifying the species as the tea shot-hole borer (TSHB) E. fornaticus; but after further analysis, the species was renamed to the polyphagous shot-hole borer [4]. This newly named “polyphagous” shot hole borer—named polyphagous because of its ability to attack many different trees—has caused significant amounts of dieback and mortality of avocado trees [5]. As time passes, the PSHB infestation problem grows more urgent. The…

become a conservation threat to rare native species, community, and ecosystems (Gundale 2002; Hale et al. 2006; Nuzzo et al 2009; Maerz et al. 2009; Sutherland et al. 2011; Nuzzo et al. 2015). In 2011, Sunderland and coauthors identified earthworm invasions in previously earthworm free regions as one of the 15 most immerging issues of biodiversity conservation. One of the reason for the issue is that invasions by European earthworms, particularly species from Lumbricidae, have substantially…

different species. Interspecific competition results from many species with similar niches and limited resources available. A niche is defined as an area that a species inhabits, the role or function of the species in the ecosystem and the species relationship with all is biotic and abiotic factors affecting it (Biology online dictionary, 2015).The limiting resources could be resources such as mates’ nutrients and space (M. Beals, L. Gross, S. Harrell, 1999). Competition exists between species…

The Pittsburgh Zoo is only one of six combinations of a zoo and an aquarium in the United States. It displays an impressive “400 different species of animals, some of which are threatened or endangered” (USNews.com). Nonetheless, the Pittsburgh Zoo strives to fashion optimistic, lifelong relations between animals and people, and this goal is evident throughout the Zoo’s walkways and exhibits. As I walked throughout the Zoo, I noticed that the animal’s exhibits closely resembled their natural…

Hypothesis originates from Elton’s conviction involving the heavy invasion of species imperfect systems. Biological Invasions, specifically invasive species are exotic species that cause environmental…

affect genes of a species, which can potentially eliminate animal spread diseases. A gene drive refers to a genetic system that manipulates a gene, guaranteeing all offspring to contain a certain dominant trait. As the trait is dominant it eventually spreads throughout the whole species, allowing them to all contain the manipulated trait. Scientists have designed this in order to eliminate mosquito-transmitted diseases such as malaria and Zika virus, but also to control species invasion. However…

snakeheads are really hurting the ecosystems of florida because they have no natural predators. The snakehead was introduced into the florida state. The snakehead was released by owners could not have them in captivity. The snakehead fish is carnivorous snake that attacks anything even if it's for fun. the snakehead has 29 different variations and all are aggressive . snakeheads are more aggressive when they have offspring . Snakehead has changed the ecosystem of florida. You can find the fish…

generations, evolving has always been the main theme for life preservation. From cavemen to businessmen, the change was a never ending possibility. Within the movie District 9, human were not the only evolving species; 'Prawns' were eventually introduced to earth later on. Clashes within the species started to occur, causing the prawns to later move into their own territory. In District 9, contact zones are highly occurring within interspecies when Wikus slowly transforms from a human to a…
