Tom Martin, Lancaster University
Tom is completing a thesis entitled Avifauna, environmental disturbance and biodiversity in two global biodiversity hotspots from data sets collected by the Op Wall teams in Honduras and Indonesia. The research project aims to examine the relationship between avifaunal communities and anthropogenic environmental disturbance in two highly important yet poorly researched ornithological regions; Neotropical cloud forest in Honduras and lowland Wallacean rainforest in Indonesia. The thesis focuses particularly on assessing the vulnerabilities of the range-restricted and endemic bird species, which are characteristic of these study sites, and also on examining the extent to which avifauna populations can be utilised as bio-monitors for biodiversity as a whole.

Natalie Bown, Newcastle University
Natalie is doing her PhD at Newcastle University with financial and field support from Operation Wallacea Honduras marine reseach programme. Her thesis is entitled Governance of Marine Protected Areas: A Case Study of the Cayos Cochinos MPA. The study examines how governance (local and national) affects the effectiveness of the management plan at the CCMPA in achieving its conservation and fisheries management objectives based on the ecological and socioeconomic criteria stated in the management plan. The study is framed by an examination of the process of Adaptive Co-Management (ACM), and how that framework can be best applied to the CCMPA, or if indeed external forces (national policy and economic development) are too strong to enable an adaptive co-management approach to work.

Jon
Shrives, Oxford University
Jon Shrives is doing his PhD at Oxford University with part financial and field support from the Operation Wallacea Honduras marine research programme. Jon is in the process of writing up his thesis and he plans to submit in early summer 2009. His Thesis title is: Integrating Oceanography and Marine Ecology: An Investigation into Riverine Impact upon the Reefs of Los Cayos Cochinos, Honduras. Some of the key questions and aims include: How effective are standard Oceanographic and Marine Geochemical techniques in explaining reef benthic community ecology. What are the principle abiotic drivers for reef benthic communities in the region? How influential are the local rivers in contributing to coral reef degredation. What are the principle concerns for loss of hard coral cover in Los Cayos Cochinos? Is there evidence for a relationship between proximity to riverine sediment and increased coral disease activity? The research has taken place over three full summer seasons on Cayos Cocinos, Honduras and involves aspects of coral reef ecology and impacts. In particular, he has studied the ecological interactions of coral diseases and other indicators of reef health with abiotic (water chemistry and physic) and biotic factors (algal productivity and domination). These factors are being related to anthropogenic sources such as pressures from local village activities and river runoff from the mainland.

Jess Harm, Oxford University
Jess Harm is doing her PhD at Oxford with field support from the Operation Wallacea Honduras marine research programme. Jess Harms thesis title is: The Relationship Between Coral Reef Fish (Larvae, Juveniles, and Adults) and Mangroves: A Case Study in Honduras. She hopes to investigate several questions including; will an island with mangrove lagoons house a different fish assemblage than an island without mangrove lagoons? Are fish in mangrove lagoons distributed according to differences in abiotic (salinity, dissolved O2, nutrients) and biotic (presence of filter feeders and algae) factors? What mangrove prop-root characteristics attract coral-reef fish juveniles? |

Jose Nunez-Mino, Oxford University
Jose Nunez-Mino is doing his PhD with financial and field support from the Operation Wallacea Honduras forest programme as part of a CASE NERC studentship. His thesis is entitled “Biodiversity Indicators and Conservation Priorities for Cusuco National Park, Honduras”. This research is looking at how the structure and pattern of biological diversity across various taxonomic groups varies in relation to habitat structure, spatial location, altitude and disturbance in what is a highly heterogeneous tropical montane forest park. On the applied side, the information will enable the focusing and prioritising of conservation targets for a management plan as well as provide guidelines for sustainable long term monitoring.” |

Dr Nancy
Priston, Cambridge University
Nancy Priston did her PhD at Cambridge University with support for the travel and field work elements in Indonesia from Operation Wallacea. Her thesis was entitled Crop-raiding by Macaca ochreata brunnescens in Sulawesi: Reality, perceptions and outcomes for conservation. This study assessed how and the extent to which the booted Sulawesi macaque (Macaca ochreata brunnescens) poses a threat to subsistence farmers’ livelihoods, and in turn, how this affects farmers’ perceptions of a threatened primate species. Through interviews with local farmers, farm surveys, focal-farm watches and troop follows, the impact of raiding by primates on subsistence farmers in Buton, South-east Sulawesi, was investigated.

Dr
Richard Unsworth, Essex University
Richard Unsworth did his PhD with financial support from Operation Wallacea on Hoga Island, SE Sulawesi, Indonesia. His thesis was entitled Aspects of the Ecology of Indo Pacific Reef Systems and has resulted in 10 papers in peer reviewed journals to date. This three year PhD thesis project investigated aspects of the functions of seagrass ecosystems in supporting the faunal productivity of Indo-Pacific coastal marine systems. The Wakatobi Marine National Park, Indonesia was used as an example of seagrass habitats throughout the Indo-Pacific bioregion. Research investigated how seagrass is utilised as habitat and as a direct food resource, this included extensive investigation on the role and extent of the impacts of habitat connectivity on seagrass fauna. Five of the six thesis chapters are published as academic papers. The complete thesis can be downloaded here. Dr Richard Unsworth is now based at the Northern fisheries Centre in Cairns, Australia following a spell working for a corporate environmental consultancy.

Dr Leanne Cullen, Essex University
Leanne Cullen did her PhD with financial support from Operation Wallacea on Hoga Island, SE Sulawesi, Indonesia. Her thesis was entitled Marine resource dependence, resource use patterns and identification of economic performance criteria within a small Indo Pacific island community. This study used the example of Kaledupa to provide a detailed case study of a small island community with high natural resource dependence. The study details natural resource use patterns and the extensive local complexities that must be understood for any chance of management success, it also highlights the importance of marine resources to the local economy. A series of potential economic performance criteria were developed which could be used in the development of appropriate management plans that aim to maintain ecological wealth and develop sustainable utilisation, whilst maintaining or improving the economic status of local user groups and maintaining local participation and support. |

Dan Exton, Essex University
Dan Exton has been working with Operation Wallacea for a number of years now, carrying out research into a range of topics regarding coral reef ecology. After focusing on the functional ecology of reef fish species, and the environmental impacts of subsistence fisheries techniques, he is now working on his PhD titled 'Isoprene Production in the Marine Environment'. Isoprene is produced by autotrophs as a thermotolerance mechanism, and Dan is hoping to fill the large gap in the literature regarding marine sources of this important gas by investigating the level of production in various taxonomic groups and the mechanisms behind emission rates. |

Dr
Steve McMellor, Essex University
Dr Steve McMellor collected data from Op Wall sites in Indonesia, Egypt and Honduras and developed a thesis entitled Biotic Indices of Reef Health. His research was based around the development of a classification scheme for coral reef health and also an Index of Biotic Integrity to act as a diagnostic monitoring and management tool. There have been many calls for such an Index in the literature, yet there still remains no widely accepted method for quantifying the health of a coral reef. Such an index will allow the monitoring of management actions as well as increasing social capital by allowing the involvement of many different stakeholders by communicating results of monitoring at many different levels.

Ian Hendy, Portsmouth University
Ian is collecting data for his PhD from the mangrove sites in Indonesia and is developing a thesis on Niche creation for cryptofauna by teredinid bivalves in mangrove ecosystems. Extensive field surveys of the mangroves provide a comprehensive assessment of the forest structure and standing stock of large woody debris. Wood-boring animals and cryptic communities found living within the galleries made by the wood-borers are then identified. In situ experiments using wooden panels provide rates of decay and wood consumption rates over temporal and spatial parameters. Laboratory work will be undertaken to further expand the project. |

Cordula Lennkh University of Glamorgan
Cordulas thesis is entitled Remote sensing evaluation of forest types in Cusuco National Park, Honduras, Central America. The study aims firstly to deliver a first description of forest vegetation for the Cusuco National Park area and secondly to develop a small scale classification scheme for tropical forest vegetation which can be used in combination of high resolution remote sensing data. The smaller scale will in future help to detect changes within the forest types. In addition the usability and accuracy of a standard remote sensing program (ERDSA Imagine) is evaluated for the new classification scheme. |

Sebastian Hennige, Essex University
Sebastian Hennige is collecting field data at the Op Wall Indonesian marine research site for his thesis on The Role of Photoacclimation on Distribution of Hermatypic Coral Species. New techniques in fluorescence are being used to assess zooxanthellae photophysiology in a variety of coral species. Experiments use non-invasive and invasive techniques to provide a detailed characterisation of the growth and productivity of zooxanthellae in different coral species. All measurements are being repeated upon in hospite zooxanthellae and isolated zooxanthellae in culture suspensions to understand the physical contribution of the host upon zooxanthellae photoacclimation. The genetic strain (clade) of all isolated zooxanthellae will also be determined. In situ work in Indonesia complements the laboratory data.

Niall Mccann, Cardiff University
Niall McCann is doing his PhD at Cardiff University with financial and field support from Operation Wallacea Honduras forest programme as a part of a CASE BBSRC studentship. His thesis is entitled "Habitat fragmentation and dispersal in Baird's tapir." This project will examine the effects of forest fragmentation on the distribution, population structure and viability of Baird’s Tapir in Honduras. Understanding the impact of fragmentation is key to managing this and other species in the region. This study will use patch occupancy analysis based on tracks and signs and DNA profiling of fecal samples to assess tapir populations in a range of forest protected areas of different sizes and degrees of isolation. Habitat surveys and spatial analysis using GIS will identify the factors affecting occupancy. These sources of information will be combined to model the impacts of increases in fragmentation and connectivity on tapir populations in Honduras and throughout Central America, providing crucial information for the management authorities, with whom Operation Wallacea work closely. Baird's tapir is Central America's largest mammal and is listed as Endangered by IUCN. It is hoped that this study will provide a management template that can be used in the conservation of other endangered large mammals.

Ben Green, Essex University
Ben Green is collecting field data on Hoga for his thesis entitled Spatial Ecology of Fish Populations of Wetland Habitats, which in Indonesia involves considerable work in the mangrove forests around Hoga. Mangroves are important and often overlooked ecosystems, vital for the functioning of the whole tropical marine environment. His work involves identifying factors that determine the structure of the fish populations that inhabit the mangroves at high tide. Another interest is habitat connectivity, in particular the movement of fish larvae between mangrove, seagrass and reef habitats.

Dr Sarah Pilgrim
Sarah's thesis was entitled “A Cross-Cultural Study into Local Ecological Knowledge”. For decades now, since the birth of industrialisation, human populations, particularly in the Western world, have become less and less reliant upon and connected with their local land. With this departure from the land has come a departure from traditional knowledge systems. Generations of accumulated observations are being lost or replaced by modern knowledge systems. With industrialisation now spreading to remote regions threatening traditional knowledge bases, this investigation looked at inter- and intra-cultural variation in knowledge, particularly in terms of economic development and resource dependence within communities in the UK, India and Indonesia. |
