Background The increasing number of chromosome-level genome assemblies has advanced our knowledge and understanding of macroevolutionary processes. Here, we introduce the genome of the desert horned lizard, Phrynosoma platyrhinos, an iguanid lizard occupying extreme desert conditions of the American southwest. We conduct analysis of the chromosomal...

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)...

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...

The characteristics of coral reef sampling and monitoring are highly variable, with numbers of units and sampling effort varying from one study to another. Numerous works have been carried out to determine an appropriate effect size through statistical power; however, these were always from a univariate perspective. In this work, we used the pseudo...

Coral disease research encompasses five decades of undeniable progress. Since the first descriptions of anomalous signs, we have come to understand multiple processes and environmental drivers that interact with coral pathologies. In order to gain a better insight into the knowledge we already have, we explored how key topics in coral disease resea...

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...

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
This study aimed to determine spatial variability of juvenile corals abundance at different spatial scales in Venezuela. Coral recruitment refers to the processes allowing maintenance and renewal of coral communities. Recruitment success is therefore indispensable for coral reef recovery after disturbances. Recruitment processes are governed by a variety of factors occurring at all spatial and temporal scales, from centimetres to hundreds of kilometres. In the present context of rising disturbances, it is thus of major importance to better understand the relative importance of different scales in this variation. Successful recruitment and survivorship of juveniles is important for shaping the community structure and population dynamics of corals. In Venezuela, most studies have focused on describing the structure of adult coral communities, while corals in their early stages have received less attention.
Project
We’ll be analyzing the trajectories of coral disease research using an extense dataset of the key aspects of this field.
