Distribution and Habitat of the Invasive Giant Day Gecko Phelsuma Grandis Gray 1870
Phelsuma 22 (2014); 13-28 Distribution and habitat of the invasive giant day gecko Phelsuma grandis Gray 1870 (Sauria: Gekkonidae) in Reunion Island, and conservation implication Mickaël Sanchez1,* and Jean-Michel Probst1,2 1 Nature Océan Indien, 6, Lotissement les Magnolias, Rivière des Roches, 97470 Saint-Benoît, La Réunion, France 2 Nature et Patrimoine, 2, Allée Mangaron, Dos d’Ane, 97419 La Possession, La Réunion, France * Corresponding author; e-mail: [email protected] Abstract. The giant day gecko Phelsuma grandis, endemic to Madagascar, was introduced to Reunion Island (Indian Ocean) in the mid-1990s. No studies have been conducted so far to define its precise distribution and habitat. To fill the knowledge gap about this invasive species, we compiled available data and performed field work during 2007-2014. We detected 13 distinct populations of P. grandis, occurring mainly in the northern part of Reunion Island and on the west coast. This gecko inhabits human disturbed areas (gardens, urban parks, bamboos, orchards, coconuts, and banana plantation) and secondary habitats (shrubby savanna, and secondary dry woodlands, secondary dry and wet thickets). Its distribution strongly suggests that saltatory dispersal (through deliberate and/or accidental transport) and natural colonization are the mechanisms of spreading through Reunion Island. All our data in combination with both P. grandis ecology and native environmental range suggested that this gecko may colonize native forest, and constitutes a potential important threat to the native biodiversity of Reunion Island (arthropods and lizards). Key words. Phelsuma grandis, Reunion Island, distribution, invasive species, conservation. Introduction Day geckos of the genus Phelsuma are distributed in the western Indian Ocean (Austin et al. -
The Gold Dust Or Flat Tailed Day Gecko)
British Herpetological Society Bulletin, No. 57, 1996 NOTES ON KEEPING AND BREEDING PHELSUMA LATICAUDA (THE GOLD DUST OR FLAT TAILED DAY GECKO) RICHARD HARLING 38 Twin Oaks Close, Broadstone, Dorset, BH18 8JF INTRODUCTION Gold Dust Geckoes are from the Comoros islands off Madagascar, as well as being introduced to other places including Madagascar itself. They are tropical lizards with an insectivorous diet, supplemented by fruit. During Easter 1995, I obtained three day geckos from a reptile shop in London. I wanted two females and a male but was unfortunately sent two males and a female - this I suspected quite quickly as the fully grown male would not tolerate one of the "females". "She" has now grown and become as big as him, has obvious femoral pores (always much more obvious that on the female) and is definitely a "him". It is generally recommended that captive-bred reptiles are best as they are tamer and more accustomed to captivity. DESCRIPTION In good light they are like living jewels. They have two horizontal bright red stripes across the top of their fairly blunt snouts up to their beautiful blue almost eye-shadowed eyes which do not have eyelids and are licked clean by their long pink tongue. There is often another red bar just behind the eyes. The posterior dorsal surface of the head and anterior half of the back is powdered with a yellowy-gold. Briefly the back is just green and then there are three bright red, "tear drops" which break up posteriorly into numerous small red spots which spread down the yellowy tail with a hint of green. -

AC29 Doc. 13.3 Annex 2 Selection of species for inclusion in the Review of Significant Trade following CoP17 To comply with Stage 1 a) of Resolution Conf. 12.8 (Rev. CoP17) and the Guidance regarding the selection of species/country combinations outlined in Annex 2 of the Resolution, the UN Environment World Conservation Monitoring Centre (UNEP-WCMC) has produced an extended analysis to assist the Animals Committee with their work in selecting species for inclusion in the Review of Significant Trade following CoP17. A summary output, providing trade in wild, ranched, source unknown and trade without a source specified over the five most recent years (2011-2015), to accompany this analysis is provided in AC29 Doc. 13.3, Annex 1. The methodology for the extended analysis was discussed by the 2nd meeting of the Advisory Working Group (AWG) of the Evaluation of the Review of Significant Trade (Shepherdstown, 2015). The AWG concluded that three criteria should be retained within the methodology (“high volume trade/high volume trade for globally threatened species”, “sharp increase in trade” and “endangered species in trade”), but that two previously used criteria added little value to the prioritisation exercise (“high variability in trade” and “overall increase/overall decrease in trade”). In addition, it was agreed to refine the methodology for “High Volume” trade to ensure that thresholds are set at a fine taxonomic resolution (order level) to ensure representation for all taxonomic orders. It was also agreed to include analysis of “Sharp Increase” in trade at the country level, as well as at the global level. -

Rediscovery of the Enigmatic Day Gecko Phelsuma Masohoala in Northeast Madagascar
Herpetological Conservation and Biology 11:402–407. Submitted: 15 April 2016; Accepted: 3 September 2016; Published: 16 December 2016. Rediscovery of the Enigmatic Day Gecko Phelsuma masohoala in Northeast Madagascar Richard C. Stanley1,3and Christopher J. Raxworthy2 1Research Associate, National Museum of Natural History, 10th Street & Constitution Avenue North West, Washington D.C. 20560, USA 2Department of Herpetology, American Museum of Natural History, Central Park West at 79th Street, New York, New York 10024-5192, USA 3Corresponding author, e-mail: [email protected] Abstract.—Phelsuma masohoala is a cryptically patterned day gecko endemic to Madagascar, and is one of the rar- est geckos known on the island. It is currently known from only four museum specimens and has not been reliably seen in the wild since 1994, despite recent attempts to find it at the type locality. Here we report the rediscovery of P. masohoala at Marojejy National Park, and review all known records of this species. Our observations provide important new data on the ecology, distribution, and behavior of this rare species, which appears to be difficult to detect due to its cryptic coloration and arboreal habits. Key Words.—conservation; distribution; Gekkonidae; Marojejy Introduction type locality, from the Tamatave area. However, doubts about the locality of this specimen have been considered Phelsuma masohoala (Raxworthy and Nussbaum sufficiently serious that it was not included in the IUCN 1994) is one of the least known species of gecko in the Red List species account (Glaw and Rakotondrazafy world. It is distinguished by its grey, black and white 2011). Photographs of this specimen in life appear in coloration; all other Phelsuma known to be sympatric Meier and Böhme (1996), Glaw and Vences (2007), and with it are primarily green.
