Introduction
My field of study is the marine benthos, with a special interest on macrofauna. As part of my work, I have participated in projects for assessing possible environmental impacts on macrofauna in the southern Gulf of Mexico. Particularly, in order to attain a background about the spatial and temporal patters in the benthos , I have developed a major affinity for amphipods, studying basic issues about them as taxonomy, diversity, ecology and biogeography.

Despite the ecological importance of sandy beaches, the diversity and distribution of macrocrustacean communities in the eastern Mexican coast (Mexican coast of the Gulf of Mexico and Caribbean Sea) remain understudied. As the first large-scale sampling effort along the eastern Mexican coast, this study aimed to estimate macrocrustacean diversity a...
The research of hydrographic variability can be performed using geospatial analyses of habitats that explicitly represent the distribution of physicochemical factors in different periods. In the present study, water characteristics were recorded monthly in four interdecadal sampling campaigns (1980, 1998, 2010, and 2016) in Terminos Lagoon. Based o...
With the aim of analyzing the biodiversity of coral reefs, specifically of the benthic marine fauna, this manual was prepared by a group of taxonomic experts to guide the adequate treatment and preservation of organisms associated with autonomous reef monitoring structures (ARMS) and thus for inclusion in scientific collections.
The distribution of biological communities is structured at multiple spatiotemporal scales. The identification of trends and patterns in highly variable coastal ecosystems contributes to explaining the relative importance of the different scales. Herein, a temporally nested hierarchical analysis was applied to a fish community in order to determine...
La diversidad biológica es un elemento natural inherente en los sistemas socio-ecológicos. De la gran diversidad de especies, existente un grupo de invertebrados de talla pequeña (2–20 mm) que habitan los suelos terrestres y los sedimentos acuáticos conocido como macrofauna. Contrario a lo que indica su nombre, la macrofauna generalmente pasa desap...
Two new genera (Paraeperopeus and Dentimelita) and four new deep-sea amphipod crustacean species of little-known genera (Neohela, Pardaliscella, Pardaliscoides and Tosilus) from the Perdido Fold Belt, Gulf of Mexico Abstract Two new genera and six new species of benthic amphipods from the soft sediments of the Perdido Fold Belt region, western Gulf...
Here we explored the potential association of the benthic macrofauna species composition with aliphatic hydrocarbons, polycyclic aromatic hydrocarbons and metals concentration detected in the sediments of the Yucatan continental Shelf (YCS), Mexico. The main objective was to provide insights on the temporal and spatial changes of such association i...
Autonomous reef monitoring structures (ARMS) have been proposed as a standardized, passive, nondestructive sampling tool. This study assessed the ability of ARMS to capture the cryptic species diversity of two coral reefs by recording species richness and taxonomic representativeness using conventional taxonomy. The capacity of ARMS, as artificial...
The biodiversity and biogeographic affinity of benthic amphipods from the Yucatan continental shelf with the warm Northwest Atlantic ecoregions were analysed using species occurrence data from benthic marine habitats of the continental shelf (< 200 m). A comprehensive collection of distributional data (presence-only) was obtained from different sou...
Here we present an occurrence dataset that contributes to the knowledge of tropical fish distribution in coastal habitats from the Terminos Lagoon Flora and Fauna Protection Area, one of the largest lagoon ecosystems in the Gulf of Mexico. Fish are high biomass keystone species in the Terminos Lagoon which provide socio-economic and ecosystem servi...
Amphipod species collected during three oceanographic campaigns (2010–2012) were analyzed to describe their spatiotemporal community distribution trends and their relationships with bottom water and sediment variables. The results show that the species richness (117 spp.) did not reach its maximum value according to the species accumulation curve (...
Gammaropsis elvirae sp. nov. is described and illustrated here, as a new species of the family Photidae Boeck, 1871, occurring on sites widely distributed in the soft-sediment habitats from the Yucatan shelf, southern Gulf of Mexico. This new species differs from all other congeners by a unique set of characteristics: lateral cephalic lobes rounded...
The community structure of tropical soft-bottom macrofauna is generally considered temporally stable. Here, we document the intra-annual variability of an amphipod assemblage from a tropical benthic habitat. The study was carried out in a shallow coastal environment of the southern Gulf of Mexico, based on historical data obtained from monthly samp...
This supplementary material includes detailed information about amphipod species collected in Alacranes Reef, such as morphological features, geographical distribution, new records, and invasive status.
The diversity and distribution of benthic amphipods has been explored in the Alacranes Reef, which is the largest coral reef ecosystem in the Gulf of Mexico. New insights into species richness, spatial distribution and extension of geographical ranges are presented by using data from published records and field surveys. A total of 117 species have...
Background
Alacranes Reef was declared as a National Marine Park in 1994. Since then, many efforts have been made to inventory its biodiversity. However, groups such as amphipods have been underestimated or not considered when benthic invertebrates were inventoried. Here we present a dataset that contributes to the knowledge of benthic amphipods (C...
Here is presented some spatiotemporal distributional trends of benthic macrofauna (amphipods) in the Yucatan continental shelf, southern Gulf of Mexico.
Elasmopus yucalpeten sp. n. (Crustacea, Amphipoda, Maeridae) from the northern Yucatan coast, with a key for the genus in the Gulf of Mexico and biogeographic comments Abstract A new amphipod species of the genus Elasmopus Costa, 1853 is described and illustrated based on material collected in a harbor on the northern Yucatan coast, southern Gulf o...
Seventeen species of caprellid amphipods have been recorded so far in the Gulf
of Mexico. New distributional and habitat data are included for 12 species.
Pseudaeginella biscaynensis has been recorded again in the Gulf of Mexico for
the first time since it was originally described 45 years ago. New morphological
information based on the development...
Dulichiella celestun, a new species of amphipod (Crustacea: Amphipoda: Melitidae) from the Gulf of Mexico, with a key and zoogeographic remarks for the genus in the western Atlantic Abstract The discovery of a new melitid amphipod in the Celestun Biosphere Reserve (northern Yucatan peninsula, SE Gulf of Mexico) is reported. Dulichiella celestun sp....
Tropical coral reefs are known to exhibit high levels of biodiversity. Amphipod crustaceans are successfully adapted to a wide range of marine habitats in coral reefs, but some regions, such as the Campeche Bank in southern Gulf of Mexico, are poorly studied or even unsurveyed for amphipods. To begin to address this paucity of information, the pres...
A new species of the genus Caribboecetes Just, 1983 is described and illustrated from specimens collected on sandy bot-toms of the northern Yucatan Peninsula, southeastern Gulf of Mexico. Caribboecetes progreso sp. nov. differs from the closely related species Caribboecetes barbadensis Just, 1983 and Caribboecetes jenikarpae Just, 1984 by the infla...
The southeast region of the Gulf of Mexico is considered to be biologically important, because it is a connection and transition zone between the Caribbean and the Gulf of Mexico, harboring great marine biodiversity. Nevertheless, benthic amphipods have been poorly studied in the Mexican southeast sector of the Gulf of Mexico with few studies listi...
To date the occurrence of Mayerella redunca has only been reported from the northern Gulf of Mexico (USA) and southern Caribbean (Venezuela). Based on samples collected from the continental shelf of Yucatan, this paper provides the first record of M. redunca from the southern Gulf of Mexico (Mexico), along with its main morphological features.
The present study documents for the first time the occurrence of amphipods in the Alacranes Reef, Gulf of Mexico. Six macrofouling assemblages were sampled from two types of man-made structures (wood docks and navigation buoys). After sorting the material, 17 species were identified. An annotated checklist for all species is provided, documenting n...
