AbstractSponges are one of the most conspicuous groups of epibionts in mangrove prop root habitats. However, with the exception of the Caribbean and the Indo-Pacific regions, studies focused on species diversity are lacking in other locations that have high mangrove coverage and are relatively distant from coral reef environments. Because mangrove-root epibiont communities, in general, have been understudied worldwide, this research contributes to filling this knowledge gap. In this study, a total of 30 sponge species (belonging to three subclasses, 14 families and 19 genera) were recorded as epibionts on prop roots of the red mangrove Rhizophora mangle in a tropical coastal ecosystem of the Southern Gulf of Mexico. Of these, five were new records for the Gulf of Mexico, 14 were new for the Mexican coasts of the gulf and 25 were new for the study area. Moreover, a similarity analysis based on presence/absence data of mangrove-associated sponges reported throughout the Western Central Atlantic region revealed that the sponge assemblage from the study area was more similar to those documented in most of the Caribbean locations (Jamaica, Cuba, Martinique, Panama, Venezuela, Belize and Colombia) rather than with those of the Northeast of the Gulf of Mexico, Guadeloupe and Trinidad. This relative intra-regional dissimilarity in the structure of mangrove-associated sponge assemblages may be related to differences in environmental conditions as well as taxonomic effort. The study area, unlike most of the Caribbean locations, is characterized by estuarine conditions and high productivity throughout the year. The inter-site variability recorded in the composition of mangrove-associated sponges was influenced by a set of factors such as salinity, dissolved oxygen and hydrodynamism. This study shows the importance of exploring the mangrove-associated sponge assemblages from different regions of the world as it furthers knowledge of the biodiversity and global distribution of this group.

Southern Gulf Of Mexico

Until now, 127 species of marine sponges have been recorded in the southern Gulf of Mexico (SGoM). In this study, we describe the sponge fauna recorded on 16 coral reefs of the SGoM, defined as the Mexican waters of the Gulf of Mexico (GoM), during a period from 2005 to 2019. We report 80 sponge species, including 34 first geographic records for the southern GoM region. The latter are fully described and illustrated, taking into account 24 that represent new records for the GoM: Agelas conifera, Agelas sventres, Agelas wiedenmayeri, Prosuberites carriebowensis, Desmanthus meandroides, Cliona aprica, Cliona dioryssa, Placospongia ruetzleri, Haliclona (Gellius) megasclera, Haliclona (Reniera) aff. portroyalensis, Neopetrosia proxima, Xestospongia arenosa, Calyx podatypa, Shiphonodictyon xamaycaense, Acarnus innominatus, Iotrochota arenosa, Polymastia tenax, Svenzea cristinae, Svenzea flava, Svenzea tubulosa, Svenzea zeai, Timea stenosclera, Stellettinopsis megastylifera, Suberea flavolivescens. The present work highlights the understimated and remarkable diversity of reef-associated sponges within the Campeche Bank Coral reef systems. Present work data was compiled with existing published information to produce an updated list of 161 known sponges in the southern GoM.

A taxonomic checklist of sublittoral tanaidaceans from the north coast of the Yucatan Peninsula, southern Gulf of Mexico, is presented in this study; it includes notes on geographic distribution, habitat, and an identification key. The genus Cacoheterotanais and the species Cacoheterotanais rogerbamberi, Mesokalliapseudes macsweenyi, Pagurotanais largoensis, Parakonarus juliae, and Psammokalliapseudes granulosus have their known distribution range within the Gulf of Mexico expanded, and are considered new records; this increases the number of tanaidacean species to 23 for the southeastern Gulf, and to 87 for the entire Gulf of Mexico.

The Impact

At the end of the Cretaceous Period (66 Ma), the impact of a meteorite on the Yucatán platform in the southern Gulf of Mexico caused the extinction of 75% of species on Earth, including 90% of planktic microorganisms like foraminifera and calcareous nannoplankton. As the ocean ecosystem struggled to get back on its feet after this calamity, the recovery of marine primary productivity was geographically heterogeneous. Some authors had speculated that this heterogeneity was driven by the uneven distribution of toxic metals in the ocean, and was directly related to distance from the Chicxulub crater. However, results from recent International Ocean Discovery Program/International Continental Drilling Program (IODP/ICDP) joint Expedition 364, which drilled the Chicxulub crater itself, found evidence of the rapid establishment of a healthy, high-productivity ecosystem in the crater within 30 kyr of the impact. This result suggests that the recovery of marine productivity is likely driven by ecological factors like incumbency and competitive exclusion. However, it also raises several additional questions: How long does high productivity last in the crater? Is this high productivity driven by the impact-generated hydrothermal system or is it a Gulf-wide phenomenon? If so, what’s driving it?Here, we examine planktic and benthic foraminifera, calcareous nannoplankton, major, minor, and trace elements, and stable isotopes from the Paleocene interval of IODP Site M0077 in the Chicxulub Crater, and compare it to publically available planktic foraminifer and nannoplankton counts from three oil wells in the northern Gulf of Mexico to determine the long term trends in productivity in the Chicxulub Crater and whether or not they are limited to the crater or extend across the Gulf. We show that the first ~million years of the Paleocene are characterized by a eutrophic surface waters that slowly transition to mesotrophic and then oligotrophic by the middle Paleocene. Foraminiferal data from the northern Gulf of Mexico demonstrates that this trend is regional.

We document multiple new records for the deep-water clingfish species Gymnoscyphus ascitus Böhlke and Robins 1970, known previously from only nine specimens collected at the type locality along the Atlantic coast of the Lesser Antillean island of St. Vincent. Five additional specimens, four from the Caribbean Sea (Mexico, Cozumel) and one from the Atlantic (north coast of Cuba), are reported.

Coral Reef System

A new species of Curidia is described based on material collected from Sisal Coral Reef System, south-east Gulf of Mexico, Mexico. It is the eighth species of this genus described worldwide. Curidia nunoi sp. nov. is morphologically similar to C. wakabarae and C. andreae. Curidia nunoi sp. nov., however, differs from these two species by a combination of several characters, including: the posteroventral spine of peduncle articles 1 and 2 of antenna 1, the distoventral spine of peduncle article 4 of antenna 2, the distal margin of coxa of gnathopod 1, the dactylus of gnathopod 2, the inner and outer plates of maxilla 1, and the distal margin of telson. The global geographical distribution of the genus Curidia is mostly from tropical to subtropical seas; five species are documented in the southern hemisphere and three in the northern hemisphere. Only C. debrogania, C. monicae, and C. nunoi sp. nov. are restricted to the Gulf of Mexico and the Caribbean Sea.
