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.
Article
Full-text available
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 of the coastal ecosystems in the Gulf of Mexico is threatened by anthropogenic activities of various kinds. The predominant portion of the land-sea margin in the State of Yucatán consists of exposed sandy beaches. This ecosystem is threatened by several activities that vary in spatial scales, at a local: cargo/fishing ports, touris...

Article
Full-text available
In a coastline with growing urbanization, we examined the condition of water and sediments in sandy beaches within a gradient of uses and modification, in contrast with a reference unmodified beach, to assess different disturbance sources and environmental impact grades. The gradient was analyzed depending on beaches proximity to the urban nucleus,...
Article
Full-text available
Diversity of macrofaunal groups in soft bottoms of the northern and southwestern Cuban shelf was assessed using taxonomic indices that depend on community structure, are independent of habitat type and sampling effort, and have a monotonic response to environmental disturbances. Taxa heterogeneity was significantly higher in sandy-muddy with vegeta...

RESUMEN Los antecedentes más significativos de esta obra son la primera evaluación que se realizó a nivel de expertos sobre el impacto del cambio climático en Cuba (Academia de Ciencias de Cuba, 1992) y el Proyecto “Impacto del cambio climático y medidas de adaptación en Cuba” (Gutiérrez, 1998), realizada en el marco del “Programa Científico Técni...
Article
Full-text available
It was assessed the possibility of segregating four species of the Laurencia Lamouroux sensu lato complex present in the Cuban shelf, using twelve macro-anatomic descriptors, some of them of meristic type, and applying descriptive statistics, the Pearson linear correlation coefficient and three multivariate techniques: K-means Clustering, Canonical...
Article
Full-text available
The health status of nine of the 35 commercial diving sites in Santa Lucia tourist resort area was assessed for the first time. Benthic indicators were used for this purpose, according to the methodology of AGRRA protocol. It was corroborated that the coral reef fringing Santa Lucia Beach is subjected to a strong and constant natural stress, due to...

Benthos condition in the coral reefs of Santa Lucia tourist resort area (northeast Cuba) before and after the pass of Hurricane Ike was determined using biological indicators of AGRRA methodology. A great reef crest decline was evident from the first sampling. Fore reef presented better conditions than the crest, mainly eastward and toward greater...

Se evaluaron los arrecifes de coral y los peces en sitios de buceo turístico en Santa Lucía, Camagüey, Cuba.
Article
Full-text available
The Gulf of Batabano is an important region of the Cuban shelf, which environmental conditions are aim of several ecological assessments. In order to contribute to the characterization of their benthic communities, the structure of the macrofauna in sediments of this shallow-water ecosystem was determined. Higher diversity and abundance of macrofau...
Article
Full-text available
En arrecifes coralinos del suroeste de Cuba, se evaluaron los impactos de la inusitada frecuencia e intensidad de huracanes entre el 2001 y el 2007, y de las enfermedades de corales, ambos factores asociados al cambio climático. En las crestas arrecifales, la reducción de la cobertura de coral duro vivo varió de nula a 21%, mientras que la reducció...
Article
Full-text available
Benthos samples in the Gulf of Batabanó (Cuba) were evaluated to explore if reported reduced lobster and finfish catches over the past two decades may be (at least partially) related to community changes and loss of benthic habitats of the gulf. Data was obtained from cruises carried out during the periods 1981-85 and 2003-04 covering the whole gul...
Article
Full-text available
The meio-and macrofauna at 20 stations pertaining to tropical seagrass meadows and mangroves were surveyed for describe their abundance and distribution patterns and also the relationships between these faunal groups. The seagrass meadows presented richer faunal in terms of density and number of taxa when compared to mangroves. The multivariate pat...

Project
National Coastal Resilience Laboratory (LANRESC) is a laboratory "without walls", created in 2015 and established in partnership between research institutions from different regions of Mexico, from the call for CONACYT National Laboratories. Of a purely academic and non-profit nature, it seeks to expand the scientific-technological capacities of different research groups on issues related to coastal resilience. Its mission is to evaluate the capacity of coastal systems and communities to recover and adapt to disturbances, through technical services, interdisciplinary and inter-institutional research, training of high-level human resources and generation of knowledge for decision-making.
Project
The main objective was to generate a baseline of marine biodiversity in sandy beaches that allows identifying potential environmental impacts and resilience in the coasts of the State of Yucatan. The sampling design was based on the MBON Pole to Pole methodology
Project
Este proyecto forma parte de una red de largo plazo (Red para el Análisis y Síntesis de la Zona Costera de Veracruz, Golfo de México) donde colaboran tres grupos de investigación (UV-UNAM). Se busca incrementar el conocimiento de línea base de las tres principales zonas arrecifales del estado: Tuxpan, Veracruz-Antón Lizardo y Los Tuxtlas. La estrategia general involucra caracterizar y vincular los componentes físicos, biológicos y socioeconómicos. La información obtenida se procesa e integra para generar estrategias de manejo de los recursos en los sistemas de estudio. (This project is part of long-term network (Analysis and Synthesis of the Veracruz Coastal Zone, Gulf of Mexico) which collaborate three research groups (UV-UNAM). It seeks to increase the basic knowledge of the three main reef areas of the state: Tuxpan, Veracruz-Antón Lizardo and Los Tuxtlas. The general strategy involves characterizing and link the physical, biological and socioeconomic components. The information about the studied reef systems is processed and integrated to generate regional strategies for resource management).
