Over the years, crustaceans have colonized various ecosystems, including the rocky marine intertidal, thanks to their adaptive capacity; however, the lack of information and studies regarding this taxon makes it difficult to know its diversity and the state of its populations. Therefore, the objective was to evaluate the carcinofauna of four rocky beaches that have geomorphological differences in the provinces of Guayas and Santa Elena, Ecuador, including their relationship with physicochemical parameters of the water through an ecological analysis with sampling based on transects and quadrats. The results indicated that these parameters do not affect the distribution and presence of crustaceans, but rather, the structural shape of the beaches, indicating that the most heterogeneous beaches harbor a greater carcinological diversity due to the variety of evolutionary morphological adaptat...

El presente trabajo tiene como objetivo determinar la relación existente entre el Liderazgo Transformacional y la Gestión Educativa del CEBA 1719 San Antonio de Padua del distrito de Jesús María, 2012. El marco teórico se basó en el estudio y la investigación y recopilación de información de autores que han aportado las bases y fundamentos sobre la teoría de liderazgo transformacional evidenciando la relación que tiene esta con la práctica de la gestión para mejorar la calidad en cuanto a todas las dimensiones presentes en la administración de las instituciones educativas. El tipo de investigación consiste en un diseño descriptivo – correlacional. La muestra estuvo constituida por 30 docentes del CEBA 1719 San Antonio de Padua del distrito de Jesús María, 2012. Se utilizó dos encuestas como instrumentos de recolección de datos medidas a través de la escala tipo Lik...

The occurrence of the fiddler crab Minuca brevifrons Stimpson, 1860 in Ecuador (Eloy Alfaro, province of Manabi) is reported for the first time. The organisms had a small patchy distribution sharing habitat in a mangrove area destined for the harvesting of the blue crab Cardisoma crassum Smith, 1870, where they established an inquilinism relationship since it lives in burrows built by the blue crab. The identification of specimens was based on taxonomic characters and bibliographic review, where the distinctive morphological feature is the width of its forehead and the oblique crest on the palm of the greater chela. This record extends its distribution on the Pacific side to Ecuador, contributing to the knowledge of biodiversity at the regional level. It is recommended to increase the studies aimed at the diversity of crustaceans at the local level to understand their biology, dynamics, ...
