Introduction
I am a marine ecologist, interested in the relationship between habitat characteristics and marine organism on reefs. Currently, I am exploring this general topic focusing on two questions: How structural complexity relates to fish assemblage on coral and rocky reefs, and how temperature affects ecological interactions on reefs. I believe answering these questions can provide valuable information for manager and policy makers.

Article
Full-text available
Increased standing macroalgal biomass in upwelling zones is generally assumed to be the result of higher nutrient flux due to upwelled waters. However, other factors can strongly impact macroalgal communities. For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence ma...

Acropora cervicornis is one of the most important coral species in shallow reefs of the Caribbean as it provides habitat and structural complexity to several species of invertebrates and fish. However, the distribution range of A. cervicornis has shrunk and collapsed considerably in the last five decades, due to a combination of factors including t...

This dataset contains 2850 photographs of the seafloor in coral communities from Venezuela that were taken during 2017 and 2018. We used a hierarchical experimental design with four random factors representing four different spatial scales: (1) region (hundreds of kilometers), (2) localities (tens of kilometers), (2) reef sites (hundreds of meters)...

Information on the status of the pillar coral Dendrogyra cylindrus across its global distribution range is needed to plan and implement effective conservation interventions at both the national and regional level. Knowledge on the species distribution and abundance on the southernmost edge of its range was limited to qualitative data gathered in th...
Article
Full-text available
Estimating variability across spatial scales has been a major issue in ecology because the description of patterns in space is extremely valuable to propose specific hypotheses to unveil key processes behind these patterns. This paper aims to estimate the variability of the coral assemblage structure at different spatial scales in order to determin...
Article
Full-text available
Lionfish (Pterois volitans) have rapidly invaded the tropical Atlantic and spread across the wider Caribbean in a relatively short period of time. Because of its high invasion capacity, we used it as a model to identify the connectivity among nine marine protected areas (MPAs) situated in four countries in the Gulf of Mexico and the Caribbean Sea....

Esta es la presentación para la charla denominada:"La historia de Playa Mero: Uso de modelos tridimensionales del bentos para estudiar las dinámicas ecológicas de corales juveniles en un arrecife perturbado.", presentada en el XII Congreso Venezolano de Ecología el 20 de noviembre de 2020. Esta presentación muestra algunos resultados de mi tesis de...
Article
Full-text available
Global and local stressors are causing the worldwide loss of coral cover and structural complexity at an unprecedented pace on reefs. In consequence, the habitat of coral reef fish has suffered a profound degradation affecting the abundance, biodiversity and species composition of this taxonomic group. Thus, understanding the link between coral ree...

Young coral ecological dynamics are fundamental to understand the recovery process of damaged reefs. In Venezuela there is a natural laboratory in Morrocoy National Park. Playa Mero reef coral cover declined from 40% to less than 5% after a massive dead event. Two decades after we asked why if there are young corals, they haven't been able to stabl...

The implantation and development of new methods aimed to assess the health status of coral reefs is a tenet core for the conservation science of these systems. For years, coral reefs communities have been described in Venezuela; however, no efforts to classify the health status of these systems have been accomplished. Part of the problem is that re...
Article
Full-text available
Abstract The study of the morphology of organisms has been fundamental for solving problems related to identification at species level, the existence of sexual dimorphism, or the role of some organisms that functions as part of the habitat. Traditionally, these studies have been approximations that involve direct measurement over the organism and p...
Article
Full-text available
In the past decade, significant efforts have been made to describe fish-habitat associations. However, most studies have oversimplified actual connections between fish assemblages and their habitats by using univariate correlations. The purpose of this study was to identify the features of habitat forming corals that facilitate and influences assem...

Eight years ago (2007), the distribution and status of Acropora palmata was quantified throughout Los Roques archipelago in Venezuela. The aim was to produce a baseline study for this species which combined population genetics with demographic data. The results highlighted that A. palmata had the potential to recover in at least 6 out of 10 sites s...

En los últimos 30 años Acropora cervicornis ha experimentado un descenso en su abundancia a lo largo del Caribe hasta el punto de caer en la categoría de “peligro crítico” en la Lista Roja de la IUCN. A pesar de su importancia regional en Los Roques, su estatus poblacional no ha sido evaluado. El objetivo de este estudio fue establecer el estado y...

Ten years ago, we studied the distribution and status of Acropora palmata at archipelago Los Roques because the actual status of this species at Los Roques was unclear in this archipelago after its regional collapse. In that opportunity we aimed to produce a baseline study for this species in Los Roques combining population genetics with demographi...

Over the past 30 years, Acropora cervicornis have experienced a decline throughout its distribution range in the Caribbean, to the point of falling within the critically endangered category of the IUCN Red List. Although, high mortality and shifts in its original distribution range have being noticed in this species at Los Roques during the last de...

The recent invasion of lionfish (Pterois volitans) in the Atlantic is considered a new threat to benthic and fish communities in the Caribbean region. This species was first reported in Venezuela in 2009 at various sites. Increasing reports in the past five years suggest lionfish has expanded its range of distribution and habitats. Nevertheless, th...

Project
The goal of this project is to describe key variables that define coral reef health across the Venezuelan Coast and Oceanic Islands. The idea is to update the health status of coral reef ecosystems in Venezuela at various spatial scales; from transects to geographical regions.
Project
To effectively conserve and manage coral reef ecosystems, we are identifying and characterizing biodiversity hotspots within the Venezuelan Caribbean region and we plan on developing a Coral Reef Atlas to portray their conservation value. Our mission is to create awareness and sensitize people about reefs importance at the local and regional levels. We will accomplish this by gathering information, finding gaps, collecting data, and ultimately developing a visually attractive, user-friendly digital interface showing reefs geomorphological and ecological units, conservation status and threats.
