Minimaliseren

For the last few years RAVON is conducting several studies in the Dutch Caribbean Islands. The small Island Saint Eustatius on the Lesser Antilles where the Lesser Antillean Iguana (Iguana delicatissima) occurs. This species is endemic to the Lesser Antilles and is threatened by a myriad of factors. Aside from this species there are also several other interesting research projects concerning reptiles.

 

ITEM: HERPETOFAUNA SAINT EUSTATIUS AND LESSER ANTILLES

  • Distribution and monitoring of the Red-bellied racer (Alsophis rufiventris) on St. Eustatius/Saba
    The endangered Red-bellied racer plays an important ecological role on both St. Eustatius and Saba. Historically the species could be found on Saba, St. Eustatius, St. Kitts, and Nevis, however, this species has been extirpated on the latter two islands due to the introduction of the Asian mongoose (Herpestes javanicus). Black and brown rats (Rattus rattus and Rattus norvegicus) have also contributed to the loss of A. Rufiventris on St.Kitts and Nevis. Despite there being black rats on St. Eustatius and Saba, the Red-bellied racer is still present in healthy numbers. However, we want to monitor the population on Saba and St. Eustatius, to be able to react on time to any changes in the population.

    For this internship you will head out in the field in search of snakes, and note all localities. If you have Paraveterinary training this is a plus as you can give snakes PIT tags for future monitoring.

    Do you have a lot of self discipline? Do you speak fluent English, and are you adventurous enough to stay on a tropical island for a couple or more months on end? Then this may be the internship for you!

  • Distribution and monitoring of the Red faced ground lizard (Ameiva erythrocephala) on St. Eustatius
    The red faced ground lizard is the largest ground lizard on the island of St. Eustatius. With its beautiful red coloured face and rosé-blue coloured body, it is a common species on St. Eustatius. Currently the species is listed as near threatened on the IUCN Red List. Sadly Black rats (Rattus rattus), dogs, and cats form a serious threat. The species has already seen a large decline on St. Kitts and Nevis due to Asian mongoose (Herpestes javanicus). Therefore it is important that we monitor the population of this species, so that we can adequately intervene if the species suddenly were to go downhill.

    For this internship you will head out in the field in search of red faced ground lizards, and note all localities. You will help set out monitoring transects across the island of St. Eustatius.

  • Search for green iguanas (Iguana iguana) and hybrid iguanas, that are invasive species on St. Eustatius
    The endangered Lesser Antillean iguana (Iguana delicatissima) has been extirpated throughout its range, and now only occurs on St. Eustatius within the Dutch Caribbean. Hybridisation with the green iguana (Iguana iguana) is considered one of the greatest threats towards the existence of I. delicatissima. To date we have discovered at least 8 hybrids, and 3 I. iguana. In order to make sure that the I. delicatissima population remains free of invasive iguanas, we need to continuously monitor the island.

    For this internship you will head out in the field in search of Lesser Antillean iguanas, hybrids, and green iguanas, and note all localities, and report any invasive species to St. Eustatius National Parks (STENAPA) and the Ministry of Agriculture and Fisheries (LVV).

  • Research into the nesting behaviour of the Lesser Antillean iguana (Iguana delicatissima) on St. Eustatius
    The endangered Lesser Antillean iguana (Iguana delicatissima) only occurs on St. Eustatius within the Dutch Caribbean. They are under increased pressure from hybridisation with the green iguana (Iguana iguana), habitat destruction, and the loss of nesting ground. We only know of a few nesting locations, and little on nesting behaviour. Next to natural nesting areas we would also like to create nesting grounds and monitor these. You will invest a lot of time in the field, locating nests and checking nests daily.
