Sceloporus grandaevus, often called the Cerralvo Island sator, is a species of lizard that can grow up to 3.2 inches in length. [2] It is found in Mexico, and is endemic to the Cerralvo Island in the Gulf of California. [3]
S. grandaevus lives in shrublands, inland cliffs, mountains peaks, and deserts of its range. This species can be found in vegetated areas, with coastal dunes and open flats nearby that have vegetation. [3]
S. grandaevus occurs in at least one protected area. Its population is stable, and although its range is only less than 200 km², it is abundant, and can adapt to changes. Its island is not very populated with humans, due to there being no water, so it is not at risk with future invasive species or natural disasters. In the future, this species may come to threat if there are invasive species, tourism, and overcollection. For these reasons, it is listed as "Least Concern" by the IUCN Red List. [3]
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
The California kingsnake is a nonvenomous colubrid snake endemic to the western United States and northern Mexico, and is found in a variety of habitats. Due to ease of care and a wide range of color variations, the California kingsnake is one of the most popular snakes in captivity.
The signal crayfish is a North American species of crayfish. It was introduced to Europe in the 1960s to supplement the North European Astacus astacus fisheries, which were being damaged by crayfish plague, but the imports turned out to be a carrier of that disease. The signal crayfish is now considered an invasive species across Europe, Japan, and California ousting native species there.
Muntjacs, also known as barking deer or rib-faced deer are small deer of the genus Muntiacus native to south and southeast Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. Most species are listed as Least Concern or Data Deficient by the IUCN although others such as the black muntjac, Bornean yellow muntjac and giant muntjac are Vulnerable, Near Threatened and Critically Endangered respectively.
The eastern fence lizard is a medium-sized species of lizard in the family Phrynosomatidae. The species is found along forest edges, rock piles, and rotting logs or stumps in the eastern United States. It is sometimes referred to as the prairie lizard, fence swift, gray lizard, gravid lizard, northern fence lizard or pine lizard. It is also referred to colloquially as the horn-billed lizard. One of its most notable behaviors is that of its escape behavior when encountering fire ants.
Crotalus mitchellii is a venomous pit viper species in the family Viperidae. The species is endemic to the Southwestern United States and adjacent northern Mexico. The species was named in honor of Silas Weir Mitchell (1829–1914), an American medical doctor who also studied rattlesnake venoms. Five subspecies are currently recognized, including the nominate subspecies described here.
Crotalus enyo is a venomous pit viper species native to the coast and islands of northwestern Mexico. Three subspecies are currently recognized, including the nominate subspecies described here.
Aloe arborescens, the krantz aloe or candelabra aloe, is a species of flowering succulent perennial plant that belongs to the genus Aloe, which it shares with the well known and studied Aloe vera. The specific epithet arborescens means "tree-like". Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, winter blooming, and attraction for birds, bees, and butterflies.
An IUCN Red List Critically Endangered (CR) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
The black jackrabbit is a species of mammal in the family Leporidae. Endemic to Mexico, its only known location is Espiritu Santo Island in the Gulf of California. The IUCN has listed this species as a "vulnerable species" because of its restricted range. This taxon is regarded by some authorities as being a subspecies of the black-tailed jackrabbit, found on the mainland of Mexico.
Ctenosaura hemilopha, also known as the Baja California spiny-tailed iguana, is a species of spinytail iguana endemic to Baja California. It is arboreal and primarily herbivorous, although it can be an opportunistic carnivore. Males may grow up to 100 centimeters (39 in) in length, while females are smaller, with a length of up to 70 centimeters (28 in). Five subspecies are currently recognized.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Peltandra virginica is a plant of the arum family known as green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba. It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant.
Amphinotus nymphula is an insect species endemic to the Seychelles group of islands. It is a restricted range species with an area of occupancy ranging 10 square kilometres (3.9 sq mi), bounded by a protected area. The primary habitat of this species is leaf litter and moss on trees in cloud forests. The species is threatened by habitat deterioration and its sensitivity to climate change. Females of the species are more often found close to the invasive plant Clidemia hirta compared to males. It is hypothesized that the invasive plant species has a negative effect on Tetrigidae as it changes the microclimate in the habitat by changing the habitat's structure and providing more shade. Possibly, the males of the species are more sensitive to any changes, as they are relatively more active than the females and may require more sunlight.
The Benoit's lanternfish is a species of widespread oceanodromous lanternfish.
The longnose tapirfish is a species of deep-sea spiny eel that lives in bathypelagic environments, and is a host of an endoparasite, Brachyenteron rissoanum.
Hypsugo alaschanicus, the Alashanian pipistrelle, is a species of bat in the family Vespertilionidae. It is found in China, South Korea, Mongolia, Japan, and Russia.
Sceloporus virgatus, commonly known as the striped plateau lizard, is a species of lizard within the genus Sceloporus. This genus is known for the signaling modalities that it uses and exhibits, including visual motion and chemical signals that aid in identifying their territories as well as color that indicates aggression. The striped plateau lizard originates from the northern Sierra Madre Occidental and is relatively small in size, measuring less than 72 mm (2.8 in) in length.
