Sharks are one of the most threatened marine animals, with fishing identified as the prime human activity responsible for population declines. The tropical eastern Pacific, a biogeographic region spanning the coastal areas from Mexico to Peru including the Colombian Pacific coast and the Galapagos archipelago, forms critical habitat and migratory r...

Deep-water environments make up 64% of the world’s oceans (nearly 202 million km2). In the past, the belief that this environment represented one of the most stable and unproductive ecosystems on the planet has been refuted by scientific research and the interest of potential productive sectors evaluating seabed resources. Human activities that thr...

In rural coastal areas of most countries of the Global South, small-scale fisheries (SSF) are the main source of food and income, and a key driver of local economies. Ensuring sustainability of SSF requires an understanding of socio-economic and cultural contexts and consideration of the drivers of fishers' behaviour, in particular in terms of spat...

Small-scale fisheries (SSF) remain a largely under-assessed and overlooked sector by governments and researchers, despite contributing approximately 50% to global fish landings and providing food and income for millions of people. The multi-species, multi-gear and data-poor nature of SSF makes implementation of traditional single-species management...

Título del proyecto: Restauración de ecosistemas de arrecife y prácticas pesqueras sostenibles frente a las costas de Esmeraldas, Ecuador Objetivo general: Preservar, gestionar de manera sostenible y restaurar los recursos marinos en arrecifes rocosos y de coral de la región costera de Esmeraldas mediante la investigación y la educación ambiental...

Small-scale multi-gear fisheries contribute half of global fisheries landings but are generally data-poor, hindering their assessment and management. Aiming to overcome various existing challenges, we used two complementary length-based approaches to assess the status of three main target species in the small-scale fisheries of Eastern Pacific coun...

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...

Observations of two of the endemic species of lizards of Malpelo Island provide new information on their natural history, ecology, and population size. Anolis agassizi, the most abundant and broadly distributed lizard, feeds mainly on insects and excrements of marine birds. It sleeps on large rocks, surfaces on hills or on man-made structures and,...

1.Worldwide, there are concerns about the potential impact of a growing tourism industry on the behaviour and ecology of sharks. Several shark species are key attractions in the scuba diving industry in both the Galápagos Marine Reserve (Ecuador) and the Sanctuary of Fauna and Flora Malpelo (Colombia).2.In this study, the reactions of five species...

Long-term monitoring data provide a basis to recognize changes in coral reef communities and to implement appropriate management strategies. Unfortunately, coral reef dynamics have been poorly documented at any temporal scale in the Southern Caribbean. Through the "National Monitoring System of Coral Reefs in Colombia" (Spanish acronym: SIMAC), we...

Este trabajo presenta datos sobre un brote de la Enfermedad de Plaga Blanca (EPB) en el banco de Serrana y resume siete años de observaciones de esta enfermedad en la vecina isla de San Andrés (Caribe colombiano). La mortalidad masiva de corales por causa de EPB se observó en la laguna del atolón (14° 27’ 53.24”, 80° 14’ 22.27” W, y 12m de profundi...

Three remote oceanic atolls, the Northern Cays (Quitasueño, Serrana, and Roncador Banks, Archipelago of San Andres and Providencia, Colombia) were intensively surveyed during April and May, 2003 through a multilevel quantitative study of the benthic communities (substrate cover: coral-benthos; densities: octocorals and urchins; frequencies: coral d...

Predicting the response of coral reefs to large-scale mortality induced by climate change will depend greatly on the factors that influence recovery after bleaching events. We experimentally transplanted hard corals from a shallow reef with highly variable seawater temperature (23–36C) to three unfished marine parks and three fished reefs with vari...

To test the hypothesis that pelagic larval duration (PLD) plays a role in the longitudinal dispersal of reef fishes, we examined the relationship between PLD and occupancy of oceanic islands among tropical eastern Pacific (TEP) snappers (Lutjanidae). We estimated PLD from analysis of the otolith microstructure of juveniles collected at 2 localities...
