Ecoparasitology monitoring of Crocodile Habitat

Project Description (Archived)

The paucity of data on community diversity of crocodilian habitats hinders the ability conservation managers to properly assess how anthropogenic disturbances affect wildlife. The trophic status and ancient phylogenetic lineage of crocodilians, as well as parasite dependency on host and environment, presents a new opportunity to use them as biological indicators of the extent to which ecosystems function. This project intends to examine the significance of parasites as biodiversity and health indicators of crocodilian habitats through a cross-disciplinary approach that includes community ecology, parasitology, eco-toxicology, and translational ecology.  

The research and biodiversity surveys are conducted in various locations around the Placencia Lagoon to examine the effects of human development and environmental changes in different areas. Surveys are conducted twice a week around the Placencia Lagoon following the PROALAS protocol (eBird). The research includes the following:

 

  1. Performing bird and terrestrial surveys
  2. Extraction of parasites from snails and fish. Examination of parasites are to utilize parasites as biological indicators of the state of the environment.
  3. Examining parasite prevalence and species richness in snails to deduce the biodiversity and species richness of the free-living community (parasite biodiversity parallels wildlife biodiversity),
  4. Conducting crocodile nocturnal eyeshine surveys to determine population density.

 
The Green Team from Turtle Inn, Projects Abroad, and various volunteers throughout the Placencia Peninsulas have teamed up with the CRC as community scientists, helping us gather bird, aquatic and terrestrial biodiversity data around the Placencia Lagoon.
