Phelsuma laticauda gecko

 

Habitat and Geography


The Phelsuma laticauda lizards typically live in humid, tropical climates with large amounts of rain and moderate to warm temperatures. They inhabit trees and other forms of brush, but not dense forests, for example, coconut palm trees, bamboo stalks, cinnamon plants, gardens or fields, and vegetation found near rivers and streams (Van Heygen, E., 2004, Hertner, G., MD, 2007). The Phelsuma laticauda species can often be observed residing in Ravenala trees in a variety of locations. This species lives in highly vegetative areas, with little to no human activity. P. laticauda has been recorded at a variety of altitudes ranging from several hundred meters to low-lying valleys between lower mountains (Van Heygen, E., 2004).    Phelsuma laticauda habitat

P. laticauda is found mainly on the island of Madagascar, but has also radiated to the nearby islands of Comoros and Seychelles (Rocha, S., Vences, M., Glaw, F., Posada, D., and D.J. Harris, 2009). In these regions, the Gold Dust Day Gecko is typically located in the northern parts, specifically the Sambirano area, and to the north east region by the coast. In addition to its endemic habitats, it has been introduced to the islands of French Polynesia and, more recently, to Hawaii in 1974. Since its arrival in Hawaii, P. laticauda has spread to many of the nearby islands including Oahu, Hawaii, Kauai, Maui, and Molokai (Goldberg, S.R., and F. Kraus, 2011). The major theory of the adaptive radiation of the Phelsuma genus is that the genus originated from Madagascar, and migrated to the surrounding regions, including the archipelagos and islands. Another theory, while less supported, suggests that the genus Phelsuma originated in Southeast Asia and migrated to the islands of the Southwest Indian Ocean. This theory is typically not supported due to the long distance between land masses and counteractive water current of the Indian Ocean (Austin, J.J., Arnold, E.N., and C.G. Jones, 2003).

The Phelsuma laticauda is a very adaptive species capable of migrating and adapting to a variety of habitats as shown above. This allows it to thrive in many tropical areas from Madagascar all the way to the Hawaiian Islands. This species lives in competition with other varieties of the genus Phelsuma, such as the P. madagascariensis grandis, P. quadriocellata parva, P. abbotti chekei, and P. seippi. The Phelsuma laticauda also shares its habitat with numerous species of geckos, lizards, insects, and mammals (Van Heygen, E., 2004).

In areas with a higher population of humans, Phelsuma laticauda are at risk of losing their environment to farmers through a process known as “tavy”, which means slash and burn method of deforestation (Van Heygen, E., 2004). Due to the poverty of the area, the farmers are highly dependent on the land for its natural resources, so they cut down and burn certain areas of the forest in order to grow their crops. While the Phelsuma laticauda is a very successful and adaptive species, this destruction of their habitat could impact their rate of survival in the future.
