Despite an expansion of marine protected areas (MPAs), a big gap exists in monitoring and evaluating their effectiveness. In less developed countries such as the Philippines, community-based (CB) MPAs have flourished. This thesis focused on exploring how local communities identify indicators of MPA effectiveness and subsequently monitor and evaluate an MPA. I first examined the …
My research, focused on the industrial shrimp fishery in southern Gulf of California, aimed to determine whether tropical shrimp trawling is a problem for viability of incidentally captured small fish species. My first objective was to use life history information to evaluate possible impacts on four small fish species from their incidental capture. I applied …

Molecular genetic studies of European seahorses revealed the presence of two native species (European long snouted seahorse Hippocampus guttulatus and European short snouted seahorse Hippocampus hippocampus) the primary focus of the present study. Ecological studies across the entire geographic range of the species confirmed low density and patchy population distribution. Habitat and holdfast preferences were …
No-take marine reserves are a highly advocated tool to recover degraded marine ecosystems, but we have limited evidence as to how marine reserves facilitate recovery of marine communities. To address this limitation, we conducted monthly underwater visual censuses over three years on 423 reef fish species in eight sites where fishing had been excluded for …

This study focuses on communities in conservation in central Philippines, with reference to marine protected areas. It analyzes communities as intersections of multiple actors with stratified interests and power, involving complex processes of place-making, ecological knowledge, tenure, governance, markets, and negotiation with domestic and international non-governmental organisations (NGOs). As rights to places are fundamentally at …
This thesis provides the first direct comparison between – and integration of – community-based and science-based approaches to the establishment of marine protected areas (MPAs). MPAs are one potentially effective conservation tool, but are being established very slowly. My research shows that community involvement in placing MPAs can help meet many ecological goals, although biophysical …
