Accounting for the other 95% : conservation and assessment of data limited marine invertebrates in the Central Philippines

Intense human pressures require that conservation be nimble and action-oriented even in the face of significant data limitations. In the ocean, invertebrates comprise over 95% of animal biodiversity and are a major component of fisheries catch. Yet, exceedingly little effort is dedicated to supporting conservation of these taxa. The goal of this thesis is to … Read more Accounting for the other 95% : conservation and assessment of data limited marine invertebrates in the Central Philippines

Measuring the long-term success of small-scale marine protected areas in a Philippine reef fishery

Tropical coral reefs are subject to multiple pressures from both natural and anthropogenic sources. These pressures have caused widespread declines in reef health, resulting in the increased use of spatial management tools such as marine protected areas (MPAs). MPAs have proven generally effective if well designed and enforced, but there are limited long-term studies investigating … Read more Measuring the long-term success of small-scale marine protected areas in a Philippine reef fishery

How much is enough? Improving participatory mapping using area rarefaction curves

Abstract Participatory mapping is a valuable approach for documenting the influence of human activities on species, ecosystems, and ecosystem services, as well as the variability of human activities over space and time. This method is particularly valuable in data-poor systems; however, there has never been a systematic approach for identifying the total number of respondents … Read more How much is enough?

Conservation prioritization for seahorses (Hippocampus spp.) at broad spatial scales considering socioeconomic costs

Highlights Protecting marine species requires conservation plans at broad scales. Yet broad-scale conservation planning is rare and difficult for marine species. We use Marxan to set priority habitats for seahorses in China and globally. We find existing marine protected area cannot sufficiently conserve seahorses. Seahorses need more protection in Hawaii, South Africa, Australia, and Asia. … Read more Conservation prioritization for seahorses (Hippocampus spp.) at broad spatial scales considering socioeconomic costs

Marine reserves drive both taxonomic and functional change in coral reef invertebrate communities

A leading argument for no-take marine protected area (marine reserve) establishment is their contribution to the conservation of biodiversity, but the impacts of reserves on ecosystem functioning have seldom been quantified. This is unusual given the value of services provided by ocean ecosystems to human well-being. While no single index can describe ecosystem function, a … Read more Marine reserves drive both taxonomic and functional change in coral reef invertebrate communities

Tropical invertebrate response to marine reserves varies with protection duration, habitat type, and exploitation history

Macroinvertebrates play a critical role in marine processes, are important in global fisheries, and make up the vast majority of ocean biodiversity, yet are largely overlooked in fisheries stock assessment and conservation. Marine reserves are a heavily advocated method for promoting recovery of marine biodiversity, but the design of reserves and the methods for evaluating … Read more Tropical invertebrate response to marine reserves varies with protection duration, habitat type, and exploitation history

Conservation prioritization and ecology of data-poor marine species under human pressures

Securing a healthy and biodiverse ocean is vital to our human wellbeing. However, marine conservation is challenging, especially for data-poor species, whose habitats and threats are understudied. My dissertation explored how to address such challenges at two large spatial scales (in China and globally), with a focus on the little studied seahorses (Hippocampus spp.). In … Read more Conservation prioritization and ecology of data-poor marine species under human pressures

Gender and marine protected areas: a case study of Danajon Bank, Philippines.

Abstract In this paper, we examine the role of gender in community-based management of marine protected areas (MPAs) in the Central Philippines. MPAs are a common conservation and fisheries management tool in this area, but the relationship between gendered fishing practices and participatory MPA management is rarely considered. In this region, women and men’s fishing … Read more Gender and marine protected areas: a case study of Danajon Bank, Philippines.

Costs and benefits of changing sampling methods in long-term monitoring of marine protected areas

To confirm their effectiveness, long-term monitoring of marine protected areas (MPAs) is critical. Such longitudinal sampling can, however, pose problems of methodology, particularly as more preferred tools may evolve over time. My research sought to understand how two commonly used methods, line intercept transect (LIT) and photoquadrat (PQ), which were used sequentially in MPA monitoring, … Read more Costs and benefits of changing sampling methods in long-term monitoring of marine protected areas
