“bully” towards native species of fish? Of course not! After all‚ they’re rainbow right? Doesn’t that mean they’re just kind and happy? Well‚ rainbow trout aren’t all lollipops and cotton candy. In fact‚ they are an invasive non-native species in Canada‚ threatening our very own salmonids‚ brook trout and Atlantic salmon. Rainbow trout is a species of fish that is native to the Pacific drainages of North America. They are included in the top 100 of the world’s worst invasive species. After many years

ocean temperatures‚ nonnative species are slowly taking over certain native species. The effects of climate change on communities can occur via both direct impacts on the diversity and abundance of native species and indirect effects due to increased dominance of introduced species. These invasive species can live in more of a broad range of temperatures than the native species‚ and in these broader ranges the native species will attempt to compete with this invasive species for resources and lose.

An invasive species are often defined as animals‚ plants or microbes that are found apart from its native land and affect the economy‚ ecology and even the way of life for other species. For this reason‚ the Osteopilus Septentrionalis is now an invasive species to Florida. The Osteopilus Septentrionalis‚ also known as the Cuban Tree frog‚ is native to Cuba and has become an amazingly invasive species to the United States‚ within the last hundred years. It is believed to have come from Cuba as a stowaway

visble. As you can see the It only takes up a minute fraction of where they use to roam free. These animals that we are killing have all been roaming the Earth long before we came. We are destroying the ecosystem. "…humans are the ultimate weed species... We have shown an incredible ability to invade‚ change‚ and inhabit every habitat type on the planet." This is a quote from a renowned zoologist and this is exactly the truth. Why do you think it is so crucial for us to save as many speicies

The introduction of foreign species to Hawaii has greatly affected the populations of the islands’ native species. In many cases‚ the introduction of foreign species has wiped out the entire population of certain species‚ rendering them extinct. This is especially devastating because many of these species are endemic‚ meaning they are found only in one particular location and nowhere else in the world. The majority of species living in Hawaii are the result of thousands of years of island biodiversity

This study is focused on stream and landscape modifications and their effects on interaction between two predatory fish: brown trout and walleye. Both species in the Au Sable River system make extensive long-range movements.

Invasive species means an organism that is not naive to a habitat and may have negative effects on the environment. The creeping water primroses are yellow in all seasons except winter. The yellow flower is very distinctive of creeping water primrose. Flowers vary in size from 1 inch to 2 inches in diameter. It is a perennial aquatic plant whose long stems creeping over mud or shallow water. It came from South America to the U.K. It is introduces as ornamental and water garden plant. It is first

one of the most interesting creatures in science‚ the Ambystoma mexicanum‚ or Mexican Axolotl – the smiling faced water salamander pictured below. The axolotl is endangered because of loss of habitat‚ pollution‚ and the introduction of non-native species to the lake for sport fishing. This salamander is not only endearing because of its smiling face‚ but also it is widely used in scientific research because of its ability to regrow lost limbs quickly. Even though the axolotl is successfully bred
