Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Wild Boar
The wild boar (''Sus scrofa''), also known as the wild swine, common wild pig, Eurasian wild pig, or simply wild pig, is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World. , up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually solitary ...

Brown Anole
The brown anole (''Anolis sagrei''), also known commonly as the Cuban brown anole, or De la Sagra's anole, is a species of lizard in the family Dactyloidae. The species is native to Cuba and the Bahamas. It has been widely introduced elsewhere, via the importation and exportation of plants where the anole would lay eggs in the soil of the pots, and is now found in Florida and as far north in the United States as southern Georgia, Texas, Louisiana, Tennessee, Mississippi, Alabama, Hawaii, and Southern California. It has also been introduced to other Caribbean islands, Mexico, and Taiwan. This species is highly invasive. In its introduced range, it reaches exceptionally high population densities, is capable of expanding its range very quickly, and both outcompetes and consumes many species of native lizards, like the green anole. The brown anole's introduction into the United States in the early 1970s has altered the behavior and negatively affected populations of the native Caro ...

Red-eared Slider
The red-eared slider or red-eared terrapin (''Trachemys scripta elegans'') is a subspecies of the pond slider (''Trachemys scripta''), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world. The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species. Etymology The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Watersnake
The common watersnake (''Nerodia sipedon'') is a species of large, nonvenomous, common snake in the family Colubridae. The species is native to North America.

Southern Watersnake
The banded water snake or southern water snake (''Nerodia fasciata'') is a species of mostly aquatic, nonvenomous, colubrid snakes endemic to the Midwest and Southeastern United States. Geographic range ''N. fasciata'' is natively found from Indiana, south to Louisiana, and east to Florida. In 1992, its congener '' Nerodia sipedon'' (northern or common water snake) and it were found in three sites in California by the US Fish and Wildlife Service (USFWS). In 2009, more than 300 banded water snakes were caught in suburbs of Los Angeles by the Nerodia Working Group of USFWS. Then in May 2016, the species was found in the Colorado River basin near Yuma, Arizona. Further trapping did indeed catch large numbers of them, indicating that a thriving invasive population exists in that area. Description Adults of the banded water snake measure from in total length, with a record size (in the Florida subspecies) of in total length. In one study, the average body mass of adult banded ...

Yellow-headed Parrot
The yellow-headed amazon (''Amazona oratrix''), also known as the yellow-headed parrot and double yellow-headed amazon, is an endangered amazon parrot of Mexico and northern Central America. Measuring in length, it is a stocky short-tailed green parrot with a yellow head. It prefers to live in mangrove forests or forests near rivers or other bodies of water. It is sometimes considered a subspecies of the yellow-crowned amazon (''Amazona ochrocephala''). It is a popular pet and an excellent talker. Poaching for the international pet trade has driven the species to near-extinction in the wild; around half of all wild-caught birds are thought to die in the process. Taxonomy This species is part of the ''Amazona ochrocephala'' complex, which also includes the yellow-naped amazon (''A. auropalliata''). This complex, which has been called "a taxonomic headache", is considered a single species by some authorities and split into three species by others. The split is mainly based on t ...

Japanese White-eye
The warbling white-eye (''Zosterops japonicus''), also known as the Japanese white-eye and mountain white-eye, is a small passerine bird in the white-eye family. The specific epithet is occasionally written ''japonica'', but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including the Russian Far East, Japan, Indonesia, Korea, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird. Taxonomy The warbling white-eye was described by the ornithologists Coenraad Jacob Temminck and Hermann Schlegel in 1845 from a specimen collected in Japan. They coined the binomial name ''Zosterops japonicus''. The English name "Japanese white-eye" was formerly used for ''Zosterops japonicus'' and what are now the Philip ...

Eurasian Collared Dove
The Eurasian collared dove (''Streptopelia decaocto'') is a dove species native to Europe and Asia; it was introduced to Japan, North America and islands in the Caribbean. Because of its vast global range and increasing population trend, it has been listed as Least Concern on the IUCN Red List since 2014. Taxonomy ''Columba decaocto'' was the scientific name proposed by the Hungarian naturalist Imre Frivaldszky in 1838 who described a Eurasian collared dove. The type locality is Plovdiv in Bulgaria. It is now placed in genus ''Streptopelia'' that was introduced in 1855 by the French ornithologist Charles Lucien Bonaparte. The Burmese collared dove (''S. xanthocycla'') was formerly considered a subspecies of the Eurasian collared dove, but was split as a distinct species by the IOC in 2021. Two other subspecies were formerly sometimes accepted, ''S. d. stoliczkae'' from Turkestan in central Asia and ''S. d. intercedens'' from southern India and Sri Lanka. They are now consi ...
