Article
Full-text available
Pocillopora corals, the dominant reef-builders in the Eastern Tropical Pacific, exhibit a high level of phenotypic plasticity, making the interpretation of morphological variation and the identification of species challenging. To test the hypothesis that different coral morphospecies represent phenotypes that develop in different flow conditions, w...
Article
Full-text available
Long-distance dispersal is believed to strongly infuence coral reef population dynamics across the Tropical Pacifc. However, the spatial scale and strength at which populations are potentially connected by dispersal remains uncertain. To determine the patterns in connectivity between the Eastern (ETP) and Central Tropical Pacifc (CTP) ecoregions, w...
Article
Coral reefs world‐wide are threatened by thermal stress caused by climate change. Especially devastating periods of coral loss frequently occur during El Niño‐Southern Oscillation (ENSO) events originating in the Eastern Tropical Pacific (ETP). El Niño‐induced thermal stress is considered the primary threat to ETP coral reefs. An increase in the fr...
Article
Full-text available
Identifying how past environmental conditions shaped the evolution of corals and their skeletal traits provides a framework for predicting their persistence and that of their non-calcifying relatives under impending global warming and ocean acidification. Here we show that ocean geochemistry, particularly aragonite–calcite seas, drives patterns of...
Article
Full-text available
Anthozoan cnidarians (corals and sea anemones) include some of the world's most important foundation species, capable of building massive reef complexes that support entire ecosystems. Although previous molecular phylogenetic analyses have revealed widespread homoplasy of the morphological characters traditionally used to define orders and families...

Full-text available
Coral reef science is a fast-growing field propelled by the need to better understand coral health and resilience to devise strategies to slow reef loss resulting from environmental stresses. Key to coral resilience are the symbiotic interactions established within a complex holobiont, i.e. the multipartite assemblages comprising the host coral org...

The Tara Pacific expedition (2016-2018) sampled coral ecosystems around 32 islands in the Pacific Ocean and the ocean surface waters at 249 locations, resulting in the collection of nearly 58,000 samples. The expedition was designed to systematically study warm coral reefs and included the collection of corals, fish, plankton, and seawater samples...
Article
Full-text available
Most tropical reef corals live at temperatures near 27°C and pH values near 8. Conditions outside of these can stress corals and lead to bleaching, disease, and death. However, some corals can survive in marginal or extreme habitats outside of these ranges. To date there is a paucity of knowledge about the role that associated microbes may play in...

Article
Sexual recruitment allows corals to maintain their populations through time, reach new habitats, and repopulate areas after an environmental or anthropogenic disturbance. This study aimed to estimate spatiotemporal variation of sexual recruitment along two areas of the southwestern coast of the Gulf of California (Bahía de La Paz and Bahía de Loret...
Article
Full-text available
In the emerald coral Porites panamensis, the rates of elongation and calcification of colonies are higher in males than in females, probably because of the higher energetic demands of the latter in order to cope with the development of the large planulae produced throughout the year. This differing energetic demand could also be reflected in the se...
Article
Full-text available
The dispersal during the planktonic larval period is a key feature to understand the metapopulation structure of marine fishes, and is commonly described by four general models: 1) lack of population structure due to extensive larval dispersal, 2) isolation by geographic distance where larval connectivity decreases with increasing distance between...

Antecedentes: La distribución de los corales del Pacífico Oriental está bien caracterizada, sin embargo prospecciones de campo siguen arro jando nuevos registros geográficos de los taxa. Objetivos: Presentar una recopilación detallada de las zonas de presencia del coral Pocillopora inflata, en México, aportar observaciones que extienden su ámbito...
Article
Full-text available
We developed a set of hypervariable microsatellite markers for the Pacific red snapper (Lutjanus peru), an economically important marine fish for small-scale fisheries in the west coast of Mexico. We performed shotgun genome sequencing with the 454 XL titanium chemistry and used bioinformatic tools to search for perfect microsatellite loci. We sele...
Article
Full-text available
Sea urchins play a crucial role in the health and dynamics of reef ecosystems. Diadema mexicanum is a dominant grazer and erosive agent of the substratum in reef environments in the eastern tropical Pacific. Its reported distribution extends from the middle of the Gulf of California (26° N) to northern Peru (6°23′ S), including oceanic islands. Her...
Article
Full-text available
The study of complete mitochondrial genomes (mitogenomes) revealed different gene rearrangements, highly variable markers, and delineated clades that have aided the understanding of the evolutionary history in corals. In this study, we examined mitogenomic variation of reef-building Porites corals and designed 34 primer pairs to target high diversi...
Article
Full-text available
Rising seawater surface temperatures worldwide may cause reef coral species to shift their geographical range towards cooler environments. Information on such shifts, however, remains scarce. The scleractinian coral Porites sverdrupi (Durham, 1947) is endemic to the Gulf of Califor-nia, and is considered a threatened species due to its vulnerabilit...

Full-text available
: Pocillopora corals are the q1 main reef builders in the eastern tropical Pacific. The validity of Pocillopora morphospecies remains under debate because of disagreements between morphological and genetic data. To evaluate the temporal stability of morphospecies in situ, we monitored the shapes of individual colonies in three communities in the so...

Full-text available
Abstract The mitogenome of the endemic coral Porites panamensis (Genbank accession number KJ546638) has a total length of 18,628 bp, and the arrangement consist of 13 protein-coding genes, 2 ribosomal RNA (rRNA) genes and 2 transfer RNA (tRNA) genes. Gene order was equal to other scleractinian coral mitogenomes.

Article
Full-text available
The coral fauna of the Eastern Tropical Pacific (ETP) is depauperate and peripheral; hence, it has drawn attention to the factors allowing its survival. Here, we use a genetic seascape approach and ecological niche modeling to unravel the environmental factors correlating with the genetic variation of Porites panamensis, a hermatypic coral endemic...
Article
Full-text available
Density banding provides a record of performance of coral colonies over time and across environments, and offers 3 measurable variables: skeletal density, extension rate, and calcification rate. Skeleton formation is energetically expensive for corals and may be associated with other energy-dependent processes, such as reproduction. Egg production...
Article
Full-text available
High predation by the corallivore gastropod Jenneria pustulata was observed in July 2011 in a high-latitude reef at Bahía de Los Ángeles in the northern Gulf of California. Porites panamensis corals were infested by 15 to 40 sea snails per colony (22 ± 7.25 ind 0.1 m–2 of Porites surface). Coral colonies were 20–30 cm tall and the average size of t...
