Microplastic pollution in mangroves and beaches of the Cispata marine
protected area, Colombian Caribbean Coast
- Authors: Ostin Garcés Ordóñez
  Pages: 9 - 25
  Abstract: Microplastics are emerging pollutants with a wide global distribution posing a risk to biodiversity and the livelihood of human communities. These particles are mostly transported by rivers from the inland to the marine-coastal ecosystems, where they accumulate and affect their environmental quality. The aim of this study was to evaluate microplastic pollution in mangroves and beaches of the Cispata marine protected area, Colombian Caribbean coast. In May 2018, three stations in the mangroves and two stations on the tourist beaches were selected, where microplastics were sampled in surface water and sediments, as well as visually identified under a stereoscope, counted to determine their abundance, and classified according to their shapes. Microplastic was more abundant in mangroves (from 13 to 123 items/m3 of water; from 72 to 1 668 items/m2 or from 42 to 1 825 items/kg of sediment) compared to beaches (from 0 to 0.13 items/m3 of water; from 8 to 36 items/m2 of sediment). In both ecosystems, films, foams, and fragments were the most common shapes, being related to deficient management of domestic waste, tourism, and fishing in the area. This study contributes to the knowledge of microplastic characteristics, distribution, and abundance in mangroves and beaches in the region in order to raise environmental awareness about the risks and promote actions to prevent and mitigate the negative impacts, especially in marine protected areas.

First record of the Fiddler Crab, Minuca osa from the Eastern Montijo
Gulf, Panama
- Authors: Roberto C. Lombardo-González
  Pages: 27 - 35
  Abstract: Minuca osa had been previously thought to be endemic to Pacific Costa Rica (Golfo Dulce). However, specimens fitting the description were sampled in April 2021 and August 2022 in two sites in the Eastern Montijo Gulf, Panama. Based on the morphological character correspondence between the specimens collected and the original species description, it can be concluded that Minuca osa is also present in the Eastern Montijo Gulf.

Geographic information system to plan marine expeditions in the
Sabana-Camagüey Archipelago, Cuba
- Authors: Alder Luis León-Brito, Claudia Bustamante-López, Lisadys Bárbara Dulce-Sotolongo
  Pages: 37 - 58
  Abstract: The Sabana-Camagüey Archipelago in Cuba merges conservation and economic interests associated with tourism. The intensive development of this economic activity in specific poles, such as the keys to the north of Ciego de Ávila, in addition to the effects of climate change, has generated multiple effects on their marine ecosystems. Despite being diverse, studies have been isolated and not systematic, which is the reason why the Coastal Ecosystem Research Center developed a new monitoring program to raise quality, fill in knowledge gaps, and save time and resources. This research aims to design a geographic information system (GIS) to be implemented in the planning of marine expeditions in the Sabana-Camagüey Archipelago. According to the characteristics of the study area and the particularities of the research project, a database was integrated with bio-physical and management information for the development of applications with spatial and statistical analysis tools to facilitate the proper planning of field activities. The plan for this campaign resulted in 48 suitable sites to develop the dives, grouped into 16 maritime routes, based on favorable conditions synergistically analyzed, with distribution and characteristics of marine habitats, bathymetry, and logistics, among others. The planning of marine expeditions using GIS improved organization, effectiveness, and quality and saved time and resources.

New records and morphometric and meristic data of the blunthead puffer,
Sphoeroides pachygaster (Tetraodontiformes: Tetraodontidae), from
southwestern Gulf of Mexico
- Authors: Luis Fernando Del Moral-Flores, Alondra Jazmín Castro-Martínez
  Pages: 59 - 69
  Abstract: El objetivo de esta contribución es presentar nuevos registros de ocurrencia de Sphoeroides pachygaster, con base en 8 ejemplares depositados en una colección científica, de 175-313 mm de longitud estándar y un peso de 178.7-1 010 g, que fueron capturados al sur de Veracruz, suroeste del golfo de México. En adición, se muestran y discuten datos merísticos y morfometrícos de los ejemplares capturados como soporte a la identificación.

Pycnogonids (Arthropoda: Pycnogonida: Pantopoda) from the Banderas Bay,
Mexican Pacific Coast
- Authors: Alejandrina Villatoro-Ortiz, Patricia Salazar-Silva
  Pages: 71 - 90
  Abstract: This study reports the composition of pycnogonid species associated with the fouling fauna on the docks of a tourist marina collected in September and October 2011 and Abril and June 2012, as well as the samples of algae, dead coral, and chaetopterid tubes collected by free diving at beach sites from February to April 2018. The sites studied, La Cruz de Huanacaxtle marina and surrounding beaches, are located along the Mexican Pacific, on the north coast of the Banderas Bay in the State of Nayarit. A total of 78 specimens were examined belonging to five families, six genera, and nine species. A systematic list is presented, and each species includes a brief description, information on its distribution and abundance in the studied sites. In the Cruz de Huanacaxtle marina docks, 56 organisms were recorded corresponding to three species. Eight species were found on the La Manzanilla, Burros, La Lancha and Isla María Cleofás beaches, six of which were not present on the docks. The most abundant species were Anoplodactylus sp. with 32 organisms (41%) and Nymphon lituus with 24 (31%), the latter dominant in the docks of the marina. This study constitutes the first record of pycnogonids for the north coast of the Banderas Bay, Mexico. It contributes to the knowledge of the biodiversity of the central Mexican Pacific coast and documents the pycnofauna associated with biofouling communities of a nautical marina.

Pentaceraster cumingi, new record of starfish (Asteroidea) for the
Salvadoran Pacific
- Authors: María Fernanda Ramos-Cáceres, Johanna Segovia-Prado
  Pages: 91 - 97
  Abstract: Having a biodiversity register is important for any region. In this paper, Pentaceraster cumingi is incorporated to El Salvador’s marine wealth. The objective was to document its presence in the Salvadoran Pacific. Based on photographic material, there is evidence of the existence of P. cumingi in a national reef since 2017. This species is vulnerable to be trapped in trawling nets. The densities and the ecological role it plays should be known.
