Species Extinction - Modern Species Paper Endangered Species Act joins a couple of unmistakable environmental laws in the US. It was set apart into law by Past President Nixon‚ whose key target was to keep various endangered species from being ended using whatever strategies imperative. Since it is set to guarantee certain animals that are nearing end on our planet‚ it will make people who harm or execute them a criminal. While the law has been outstandingly viable in the rebuilding of a couple

The Salt Creek tiger beetle (Cicindela nevadica lincolniana) is an example of an endangered subspecies protected under the ESA. The US Fish and Wildlife Service as well as the National Marine Fisheries Service are held responsible for classifying and protecting endangered species‚ and adding a particular species to the list can be a long‚ controversial process (Wilcove & Master‚ 2008‚ p.

Primary Post “The surrogate species approach is the most cost effective means for establishing national and global conservation priorities.” Conservationists are challenged with the problem of protecting a range of species at minimal costs. As such conservationists have to prioritize to help those in most need of assistance or trouble (Myers et al. 2000). Therefore‚ many conservationists have adopted the surrogate species approach as a shortcut to aid with the conservation priority decision (Caro

Hydrilla: An Invasive Species Hydrilla verticillata‚ otherwise known as Hydrilla is an aggressive water weed and is said to be one of the world’s worst invasive aquatic plants. Hydrilla in temperate places around the globe and somehow made its way to the United States. Hydrilla has a special advantage; it grows under lower light conditions than nearly any other species‚ it only needs about 1% of sunlight. This advantage allows hydrilla to grow underneath other plants and survive greater depths;

Aquatic Invasive Species Two thirds of the forty freshwater fish extinctions are known to have been caused by invasive species. The extinctions could have been caused by any one of the four thousand three hundred known invasive species in the United States. In Minnesota‚ the land of ten thousand lakes‚ thirty-five percent of all recreational waters are known to hold at least one invasive species (Invasive species of aquatic plants and wild animals in Minnesota: Annual report). The common carp‚ zebra

Out of all the species that have ever existed since the beginning of time‚ 98% of them are extinct (Facts). There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry‚ 2). Scientists classify species into six different groups: plants‚ animals‚ insects‚ algae‚ fungi‚ and microorganisms (Today’s Situation). In the tropical rainforest alone‚ most species are disappearing at the rate of 1% a year (Sherry‚ 6). If the current trend continues‚ at least

This article is about how human impact influences fire ant invasion the and how it changes the environment in which they thrive. Human disturbance effect many parts of the environment and when research is conducted it is difficult to conclude if the disturbance was caused by humans or biological invasion. In this research experiment‚ the researchers show human effect is projective negatively on the invasive fire ant‚ Solenopsis invicta. They took factors of human activity which was mowing and plowing

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
