Anolis allisoni, also known commonly as Allison's anole or Cuban blue anole is a species of lizard in the family Dactyloidae. The species is endemic to Cuba (except the west and the far southeast), the Bay Islands and Cayos Cochinos off the mainland of Honduras, and Half Moon Caye off the mainland of Belize. [2] [3] There is also a single doubtful record from Cozumel, Mexico. [3] Recently, the species has been documented in southern Florida. [4] [5] [6] This diurnal species is commonly seen on palm trunks, and it feeds on invertebrates. [3] It is among the relatively few anole species in which females may lay their eggs together, forming a communal nest. [7]

Etymology

The specific name, allisoni, is in honor of American philanthropist Mr. Allison Vincent Armour. [8]

Taxonomy

A. allisoni is part of the carolinensis group of anoles, a clade of mid-sized trunk-crown anoles thought to have originated in Cuba. It is very closely related to other anoles of this group such as the American green anole, Anolis carolinensis , and its Cuban "cousin" Anolis porcatus .

In terms of colour and morphology, Allison's anole is superficially similar to the better-known American green anole. While females are overall green with paler underparts, similar to the green anole, males have a reddish-pink dewlap, and typically have bright blue heads, forelegs, and frontal half of the body (in males from Honduras, only parts of the head are blue with the remaining green). [3] [9] In all individuals the throat is usually white. Both sexes are able to rapidly change their colour to brown. [3] Females reach about 7.5 cm (3 in) in snout-vent length and males about 10 cm (4 in). [10] It is one of the larger species in the carolinensis species group. Allison's anole is a typical trunk-crown anole. Like other anoles in the carolinensis group, it has a large, conspicuously triangular-shaped head, and males have a prominent nuchal crest. This lizard has large subdigital toepads, which help facilitate climbing and clinging to vertical surfaces.

Distribution and habitat

Distribution

A. allisoni is believed to have originated on Cuba but has since spread to Honduras and Half Moon Caye. This migration is believed to have occurred long ago as the different populations on these three locations display sufficient phenotypical and genetic differentiation to be considered for subspecies status. Few specimens have been identified in Mexican Banco Chinchorro island [ citation needed ]. A. allisoni has been documented in several neighborhoods within southern Florida, surviving and apparently breeding in both small parks and residential housing. This population is likely of Cuban origin and was brought to Florida as eggs accidentally ferried with plants. [6]

Habitat

A. allisoni is a trunk-crown anole, meaning that it is commonly found in the canopy and on the upper trunk of tall trees. It is commonly found up to 1.5 m (4.9 ft) off the ground. This anole has evolved large subdigital toepads, compared to most other anoles, and this adaptations helps it to cling to vertical surfaces such as the trunks of trees. This lizard is most commonly seen on coconut palm trees. Before coconuts were introduced to the island of Half Moon Caye the lizard probably occupied a similar niche in the crowns of salt water palmettos (Thrinax radiata), which was exterminated from the island in 1982. It has been suggested that this plant be reintroduced to the island to provide habitat for the lizards, especially since the coconut palm population on Half Moon Caye has been gradually declining. In more urban areas this lizard may be commonly be seen on walls and other man-made structures. It is a common sight on the island of Cuba, where its population is largest [ citation needed ]. In Florida, the introduced populations are restricted to a few neighborhoods as of 2021. Their numbers are likely growing as many residents have become aware of the lizards, which show no fear of humans and regularly climb on building walls and nest in yards. [6]

Dactyloidae are a family of lizards commonly known as anoles and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with Polychrus, but the latter genus is not closely related to the true anoles.

<i>Anolis</i> Genus of lizards

Anolis is a genus of anoles, iguanian lizards in the family Dactyloidae, native to the Americas. With more than 425 species, it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 Anolis species remain. Previously, it was classified under the family Polychrotidae that contained all the anoles, as well as Polychrus, but recent studies place it in the Dactyloidae.

<i>Anolis carolinensis</i> Species of reptile

Anolis carolinensis or green anole is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific and Caribbean. A small to medium-sized lizard, the green anole is a trunk-crown ecomorph and can change its color to several shades from brown to green.

The brown anole, 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 other regions of the United States including southern Georgia, Texas, Louisiana, Tennessee, Mississippi, Alabama, Hawaii, and Southern California. It has also been introduced to other Caribbean islands, Mexico, and Taiwan.

<i>Anolis cristatellus</i> Species of reptile

Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles. The species is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have this crest, but it is smaller than that of the males. The species is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on its throat, known as a dewlap, in order to show others how dominant it is, and thus attract mates or intimidate rivals.

The ecomorph concept is a term first coined by Ernest Edward Williams in 1972 which he defined as a “species with the same structural habitat/niche, similar in morphology and behavior, but not necessarily close phyletically.” Williams first applied this definition to the Greater Antillean anoles upon observing their evolutionary radiation, although it has since been used widely elsewhere.
