References 1. Introduction: In February 2007 the IUCN ( the World Conservation Union) classified the species of Ctenosaura melanosterna as critical endangered. The need of a studbook was born. 04 June 2007 the Studbook of Ctenosaura melanosterna was a fact. Ctenosaura melanosterna is a Spiny Tail Iguana species from Honduras. It is found on the mainland (Rio Aguan Valley) and on the islands Hog and Cayos Chochinos. The habitat on the mainland is dry subtropical/tropical forest. The habitat on the islands is tropical forest. There are not many animals in captivity. At the start of the studbook we know only 5 locations where C. melanosterna are kept. 4 in the Netherlands and 1 in the USA. Only 3 locations (Blijdorp, Gaal, Stienen) were interested in joining the studbook. The other two locations can be named traders. 2. Studbook population At present December 31, the studbook population is 3.5.24 (32). The living population however is 2.5.23 (30) 3. Location The 30 living specimens are kept on 6 locations, 3 in the Netherlands and 3 in the U.S.A. 4. Birth The location Gaal was this year the first with successful breeding of 10 hatchlings in January. The location Stienen hatched only one young in Oktober. 5. Imports There are no imports from the republic of Honduras. 6. Death At the location Gaal one hatchling died. 7. Transfers From the location Gaal 12 hatchlings will be lost for the studbook and will be send to a no participant of the studbook. That was a agreement for the male that was given to Gaal before the studbook was realised. 8. Discussion A living population of 6 (2.4) adult is animals is a very poor for the future. The species has a endangered and protected status in Honduras, so no import will be allowed. In 2008 we started a inquiry for new locations where we hope to find C. melanosterna. We use the old information of locations from W. van der Heuvel . Only one new location we found one female, bus she died after a few months. In 2008 we start a research program for C. melanosterna in the wild and captivity. We are going to rewrite the species Ctenosaura melanosterna. The information we have on this moment is very poor and not enough for a conservation program. More research is necessary. The hole research program is on the auspices of the Iguana Specialist Group/ I.U.C.N., E.S.F and Dutch Iguana Foundation and will take place on the island Cayos Cochinos and the Rio Aguan Valley on the northern mainland of Honduras (wild populations) and on the tree locations (Blijdorp, Gaal, Stienen) of the studbook in the Netherlands (captivity group). More information will be available in 2009. At the same time we start the Assurance Colony project Ctenosaura melanosterna. The goal of the project is to setup a captivity group in several Zoos in Europe. A successful presentation was held at the EAZA annual meeting in Antwerpen. 3 Zoos want to join the project (Blijdorp Zoo Rotterdam, Helsinki Zoo, Schönbrunner Tiergarten Wien). In 2009 Helsinki and Wien will get there first animals from the studbook. More information will be available in 2009. 9. References Ctenosaura Verzamelnummer deel 1, 2006 S.D.G.L.

  • ALL of YOUR EGGS in ONE BASKET: CONSERVATION of a MICROENDEMIC ENDANGERED SPECIES by LESLIE EILEEN RUYLE (Under the Direction O
    ALL OF YOUR EGGS IN ONE BASKET: CONSERVATION OF A MICROENDEMIC ENDANGERED SPECIES by LESLIE EILEEN RUYLE (Under the Direction of John C. Maerz) ABSTRACT Effective conservation of endangered wildlife requires a multi-disciplinary understanding of issues. Ecological knowledge of species combined with the effects of human activities on those species should be applied when developing conservation programs. Conservation efforts need to be evaluated for their effectiveness in meeting both ecological and social requirements for protection of species and impacts on local human populations. My dissertation sought to contribute to conservation efforts of Central America iguanas by using traditional ecological studies for foundational knowledge of a critically endangered species, Ctenosaura melanosterna, and examining the impact of humans living with that species. Additionally, I evaluated iguana farming as a conservation strategy meant to benefit local populations as well as protect iguanas. Specifically, I examined four different sites of varying degrees of human activities and the impact of those activities on C. melanosterna in regards to tick loads, tail loss frequency, behavior and density. Tick loads were correlated to ctenosaur density and tail loss frequency was correlated to presence of domestic animals. Behaviors changed to be bolder with human presence and densities of ctenosaurs were highest at sites with humans, but no domestic animals. We found human impacts depend on availability of food subsidies as well as presence of domestic animals. We provide a study on the growth and survival of C. melanosterna that will serve as a baseline for the species in monitoring programs. We also conducted a population viability analysis that suggested the species may be in decline despite conservation protection.

The species has two evolutionarily significant units (ESUs), found in the Valle de Aguán and the Cayos Cochinos Archipelago, Honduras. Each ESU has been shown to be genetically distinct and each is listed, for differing reasons, as Critically Endangered by the IUCN. Habitat destruction and overharvesting for consumption and the pet trade are among the top threats facing the mainland, Valle de Aguán, population. The Cayos Cochinos population faces similar threats to a lesser degree; however, its restricted range (2.2 km2) heightens the potential severity of these threats, and makes this population highly susceptible to the impact of hurricanes. We examined body size, demography, and body condition in both populations.

    CoP15 Prop. 11 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Fifteenth meeting of the Conference of the Parties Doha (Qatar), 13-25 March 2010 CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II This proposal has been submitted by Honduras*. EXECUTIVE SUMMARY: Iguanas of the genus Ctenosaura belong to the family Iguanidae. The genus contains 13 species native to central and south-eastern Mexico, the Yucatan Peninsula and Central America. The genus Ctenosaura includes the subgenus Loganiosaura, which contains 4 closely related species that are easy to distinguish from the rest and form what is called the Ctenosaura palearis clade or complex. The group includes the species Ctenosaura palearis (endemic to the Motagua Valley, Guatemala), C. melanosterna (endemic to the Aguán Valley, Honduras), C. bakeri (endemic to Utila Island, Honduras) and C. oedirhina (endemic to Roatán Island, Honduras). These species are in high demand in the international exotic pet trade because they are medium to small in size and they are relatively tame and easy to keep in captivity. However, their wild populations have experienced a major decline and their geographic ranges are highly restricted. It is therefore urgent to regulate international trade in these species by including them in CITES. At present, the fact that they are not included in CITES means that trade is not regulated, which could negatively affect their wild populations. Including the species in Appendix II would be essential to control trade thoroughly and ensure it does not become a direct cause of the extinction of the species.
