On coral reefs, the cleaning behaviour of certain species provides a vital ecological service to the wider reef fish community. It also gives a fascinating insight into how different species interact mutualistically in such a hyperdiverse ecosystem. In the Caribbean, cleaning is performed by both fish (primarily gobies) and invertebrates (primarily the Pederson cleaner shrimp, Ancylomenes pedersoni). Cleaner species occupy cleaning stations that are sought by client fish who perform set behaviours in order to initiate cleaning. The dynamics of these interactions are complex and span the taxonomic spectrum of the reef fish community, with Pederson cleaner shrimp alone known to service over 20 families of fish. Students will use SCUBA diving, first to map the cleaning stations present on a reef, and then to deploy remote underwater video cameras to film the natural behaviour at cleaning stations in the absence of divers. Projects could focus on drivers of client composition, or how cleaning frequency and duration varies between client species. Alternatively, projects could explore the role of habitat, structural complexity and environmental variables on cleaning station densities and distributions.

Extended Dissertation Summary

 

Honduras Marine Research Objectives

In the Caribbean, there are a number of core issues that have been affecting the biodiversity of coral reefs, including the mass mortality of keystone sea urchins that have allowed algal colonisation of reef areas, an invasive predator (lionfish) originally from the Indo-Pacific that has spread across the Caribbean, and overfishing of reef fish by local communities. Opwall has two marine research sites in Honduras where these issues and many more are studied: one is on the island reefs of Utila and the second on the coastal barrier reef of Tela. At both sites, teams of Opwall scientists and students collect annual monitoring data to assess temporal patterns in reef community health, alongside novel research to address key conservation priorities and gaps in our current understanding of these fragile ecosystems. Honduras is also home to Opwall’s pioneering efforts to integrate technological solutions into the monitoring and study of coral reefs, including our 3D computer modelling method. Opwall’s team of marine scientists in Honduras helps to support not only international academic research and new method development, but also supports local non-governmental organisations with their efforts to improve marine conservation in Honduras.

  • Develop an independent research project and write a formal proposal
  • Dive on a typical Caribbean coral reef on Utila island
  • Complete a week-long training course on Caribbean coral reef ecology
  • Learn to identify common Caribbean fish
  • Collect data using behavioural observations from remotely deployed video footage
  • Learn how to organise and analyse large data sets
  • Opwall fee
  • Cost of international flights into and out of San Pedro Sula
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. This costs around £200 or $290 on average. Extra nights’ accommodation in San Pedro Sula costs around £49 or $71.
  • Dive equipment rental – £50 or $75 per week for a full dive kit. If you only wish to snorkel and want to hire snorkel equipment, the cost is £25 or $38 per week. Please note that wetsuits/rash vests cannot be provided – you should bring your own.
  • Park entrance fees – £14 or $20
  • PADI manual and PIC card (if you are completing your Open Water qualification) – £69 or $87 approx.
  • Vaccinations and prophylactic medicines – cost can vary depending on your healthcare provider.
  • All prices in GBP or USD unless specified

Climate
Our marine sites are hot and usually dry, but with occasional storms.

Fitness level required
Low. Some fitness is required if including in-water activities, but conditions are relatively easy.

Creature comforts
Facilities are comfortable but basic. There is phone signal and limited wifi that is often unreliable.

Locations

  • Honduras
  • Utila
