Introduction
I am a biologist interested in the management of coastal resources such as mangroves and fisheries. My current research focuses on patterns of resource use over time and space, and evaluating the effectiveness of protected areas and fisheries regulations in achieving sustainable exploitation.

**A readable abstract** Sawfishes are cool but seriously in trouble. They breed up rivers and use shallow coastal areas like mangroves, and have a saw on their face which makes them very prone to getting stuck in nets - even if fishers don't want to catch them! We don't know much about them the Pacific coasts of Colombia and Panamá so we dug into t...
Article
The Eastern Tropical Pacific (ETP) comprising the coasts of Costa Rica, Panama, Colombia and Ecuador, represents an area of high marine biodiversity that supports productive fisheries and acts as an important migratory corridor for many marine species. Despite its biological importance, the ETP is understudied and lacks sufficient data for science-...
Preprint
The role of mangroves as pivotal providers of ecosystem services has been widely acknowledged. In Latin America, mangroves play an important role in traditional coastal livelihoods, but the growing economy of these nations demands the expansion of land for development, putting pressure in ecosystems such as mangroves. Here we examine the impact of...

Parrotfish (Family Scaridae) are a family of herbivorous fishes crucial to coral reef health, particularly for Caribbean reefs due to their declining coral cover. However, despite parrotfish are fully protected in some countries, they are still heavy fished in most of their Caribbean range. The consequences of this targeted fishery in the Colombian...

Full-text available
Sawfishes are considered to be one of the most endangered families of fishes in the world. Their diadromous ecology and vulnerability to fishing nets have brought most populations to the brink of collapse. Conservation of the surviving populations is hindered by the paucity of historic and contemporary catch and observational records, and assessmen...

This report details the current knowledge and available data on the fisheries and aquaculture sectors in Timor-Leste.
Article
Full-text available
Capture fisheries in small island developing states (SIDS) have the capacity to increase access to vital micronutrient-rich food to tackle malnutrition, but when fishers are restricted to nearshore habitats by limited capacity (boats, engines, fishing gear), fisheries production can be low. This is the case of coastal Timor-Leste, where some of the...
Article
Mangroves are one of the most productive ecosystems in the world, sustaining millions of coastal livelihoods. However, their area of occurrence has been greatly reduced over the last century. In this study, we identify potential drivers of land use and land cover change adjacent to mangroves on the Pacific shorelines of Colombia, Panama and Costa R...
Article
It is estimated that more than 200 million people worldwide depend on small-scale fisheries for their livelihood, driving the need for fisheries reform to develop effective, local-level governance systems to protect food security and lessen reliance on common resources. However, our ability to impose new management relies on the assessment of vulne...
Article
Full-text available
The Pacific coast of Colombia has some of the most extensive mangrove forests in South America. As an isolated region and one of the country's poorest, coastal communities rely on fishing as a main source of animal protein and income. In an attempt to reverse declining trends of fisheries resources, in 2008, an Exclusive Zone of Artisanal Fishing c...
Article
Full-text available
Changing attitudes towards wildlife is challenging, particularly in developing countries where local communities strongly depend on natural resources to survive. Here I present a case study from a small island located in the Colombian Caribbean where a team of biologists used local culture, music in particular, as the main tool to introduce and dis...
Article
From native pre-Columbian subsistence economies to the modern global economy, mangroves have played an important role providing goods and services to human societies for millennia. More than 90% of the world’s mangroves are located in developing countries, where rates of destruction are increasing rapidly and on large scales. In order to design eff...

Invasive lionfish Pterois volitans and Pterois miles are one of the greatest threats to coral reef fisheries in the Caribbean. Management currently relies solely on removal, however, there is little understanding of spatial ecology of lionfish to inform management strategies and thus, increase their effectiveness.The use of detection probability an...

The trophic ecology of epibenthic mesopredators is not well understood in terms of prey partitioning with sympatric elasmobranchs or their effects on prey communities, yet the importance of omnivores in community trophic dynamics is being increasingly realised. This study used stable isotope analysis of (15)N and (13)C to model diet composition of...
Article
In view of current worldwide coral reef decline, and the shortcomings of traditional top-down management schemes of Marine Protected Areas (MPAs), decision makers and scientists face the important challenge of developing new approaches to generate effective conservation strategies. This study evaluates MPAs as linked social–ecological systems (SES)...
Article
Full-text available
The structure of animal movement paths at varying spatial scales allows insight into the importance of habitat distribution and their response to scale in heterogeneous landscapes. Home-ranging animals typically exhibit constrained random movements at large spatial scales, with small-scale orientation reflecting responses to sensory stimuli. The so...
Article
Full-text available
Localized and global impacts are responsible for driving the current decline in coral reef ecosystems. The worldwide debate over the efficacy of Marine Protected Areas (MPAs) as a conservation measure for coral reefs highlights the importance of acquiring accurate indicators of reef resilience and recovery under stressful conditions. Marine benthic...
