Abstract

Se presenta una lista sistemática de 7 especies de gasterópodos sacoglosos recolectadas desde marzo de 2013 hasta enero de 2014 en el estado Nueva Esparta y Los Frailes. En dicha lista, Elysia serca Marcus, 1955 y Elysia cauze Marcus, 1957 se registran por primera vez en Venezuela. Adicionalmente, se propone una clave de identificación para estos animales.

Translated abstract

A systematic list including 7 species of sacoglossan gastropods collected between March 2013 and January 2014, from Nueva Esparta state and Los Frailes is herein presented. In this list, Elysia serca Marcus, 1955 and Elysia cauze Marcus, 1957 are recorded for the first time in Venezuela. In addition, an identification key for these animals is proposed.

Marine Biodiversity in the Caribbean: Regional Estimates and Distribution Patterns

Patricia Miloslavich, JUAN MANUEL OSPINA-DÍAZ, Eduardo Klein … (2010)

This paper provides an analysis of the distribution patterns of marine biodiversity and summarizes the major activities of the Census of Marine Life program in the Caribbean region. The coastal Caribbean region is a large marine ecosystem (LME) characterized by coral reefs, mangroves, and seagrasses, but including other environments, such as sandy beaches and rocky shores. These tropical ecosystems incorporate a high diversity of associated flora and fauna, and the nations that border the Caribbean collectively encompass a major global marine biodiversity hot spot. We analyze the state of knowledge of marine biodiversity based on the geographic distribution of georeferenced species records and regional taxonomic lists. A total of 12,046 marine species are reported in this paper for the Caribbean region. These include representatives from 31 animal phyla, two plant phyla, one group of Chromista, and three groups of Protoctista. Sampling effort has been greatest in shallow, nearshore waters, where there is relatively good coverage of species records; offshore and deep environments have been less studied. Additionally, we found that the currently accepted classification of marine ecoregions of the Caribbean did not apply for the benthic distributions of five relatively well known taxonomic groups. Coastal species richness tends to concentrate along the Antillean arc (Cuba to the southernmost Antilles) and the northern coast of South America (Venezuela – Colombia), while no pattern can be observed in the deep sea with the available data. Several factors make it impossible to determine the extent to which these distribution patterns accurately reflect the true situation for marine biodiversity in general: (1) highly localized concentrations of collecting effort and a lack of collecting in many areas and ecosystems, (2) high variability among collecting methods, (3) limited taxonomic expertise for many groups, and (4) differing levels of activity in the study of different taxa.
