Article
Full-text available
Coral reefs provide numerous ecosystem services and host more than 20% of marine biodiversity. However, the impact of recreational SCUBA diving on coral reefs is not often quantified in marine protected areas. We quantified the impact of divers on coral reefs in five sites within the National Park Reefs of Puerto Morelos, Mexico during high and low...

Since late 2014, the Mexican Caribbean coast has periodically received massive, atypical influxes of pelagic Sargassum spp. (sargasso). Negative impacts associated with these influxes include mortality of nearshore benthic flora and fauna, beach erosion, pollution, decreasing tourism and high management costs. To understand the dynamics of the sarg...
Article
In 2018, the Mexican Caribbean coast received a massive influx of pelagic Sargassum spp. that accumulated and decayed on beaches producing organic decomposition products that made the water turbid and brown. Between May and September of the same year there were several reports of mass mortality of marine biota in this area. From these reports we es...

Article

Marine ecosystems are under anthropogenic pressures degrading both biodiversity and functional diversity. Functional diversity studies identify species functions through trait analysis, and are a robust alternative to the classical taxonomic approach. Although trophic traits are considered predominantly when analyzing functional diversity on marine...

There is an increasing need to examine regional patterns of diversity in coral-reef systems since their biodiversity is declining globally. In this sense, additive partitioning might be useful since it quantifies the contribution of alpha and beta to total diversity across different scales. We applied this approach using an unbalanced design across...
Chapter
Full-text available
We investigated the current patterns of diversity by country and by class of echinoderms, and analyzed their biogeographical, depth, and habitat or substratum affinities, using the database of the appendix of this book. Traditionally, the area has been divided into five biogeographical Regions and nine Provinces that cover a wide climate range. Cur...
Chapter
Full-text available
This chapter presents a historical review of the study on living and fossil species of the Phylum Echinodermata of Venezuela; most of the research has been carried out in the middle-western and eastern coasts of the country. There is currently a total of 234 species of echinoderms known from Venezuelan waters, with 97.87 % of them from the Caribbea...
Chapter
Full-text available
This chapter presents a summary of studies on echinoderms on the Ecuadorian continental shelf and at the Galápagos Islands. The geographic, climatic and oceanographic contexts, as well as the general characteristics of ecosystems and communities are discussed first to better understand the diversity of echinoderms and their distribution in Ecuador....
Article
The sand dollar Dendraster excentricus is a facultative suspension feeder, which is relatively rare within the Order Clypeasteroida. Field studies of regulation of its feeding mode have been mostly conducted in exposed coastal habitats, where they are typically observed in an inclined position and oriented parallel to each other during suspension f...
Article
Full-text available
Species of the Order Clypeasteroida (Echinodermata: Echinoidea) from the Venezuela coasts. In Venezuela, taxonomic studies of echinoids are scarce, and most of the information is scattered in bibliographic sources or in collections from scientific expeditions deposited in foreign museums. With the aim to compile information about the species divers...

Article
Dendraster excentricus is a common sand dollar of nearshore benthic habitats along the west coast of North America, and has the ability to feed either on deposited or suspended food particles. Field surveys and manipulative experiments demonstrated that intraspecific density and sediment organic matter (SOM) content of sediments are among the facto...

We studied the taxonomic structure of the herpetofauna to assess the Pinus caribaea forests' effect on natural savannas in Uverito, and its possible recover, after harvesting. The herps were collected monthly, during one year, with pitfall traps in Uverito, Monagas State, Venezuela. We found 5 species of lizards (Ameiva ameiva, Cnemidophorus lemnis...
