    Beschreibung: Se utiliza la información de perfiles de playa en cuatro localidades de las Playas del Este obtenidos en los últimos 27 años, para describir la tendencia de la playa a mediano plazo. A partir de datos de posición de la línea de costa y de volúmenes de arena de la playa emergida se estableció la tasa de cambio de la playa utilizando la regresión lineal simple. Los resultados confirman la tendencia erosiva de un sector de la playa de Guanabo. La tasa anual de retroceso de la línea de costa ha sido de -0.97 m/año que ha establecido un cambio total de - 26 ±7 m. La reducción de los volúmenes de arena ha sido de -28 ± 8 m3/m, a un ritmo de -1.04 m3/m/año. En la playa de Santa María, la línea de costa en algunas localidades ha experimentado retroceso y en otras ha ocurrido poco cambio, sin embargo en todos los casos se ha producido un incremento notable en los volúmenes de arena de la playa emergida debido a la formación y crecimiento de las dunas. La reactivación de los procesos eólicos que dio lugar al restablecimiento de la morfología de dunas fue posible por la eliminación del bosque de casuarinas que, durante más de 20 años, ocupó la zona posterior de la playa.
    Beschreibung: The information of beach profiles, obtained during the last 27 years in four localities of Playas del Este, is used to describe the medium-term tendency of the beach. Starting from data of the shoreline location and sand volumes of the emerged beach, the beach change rate was established applying simple linear regression. The results confirm the erosive tendency of a sector in Guanabo beach. The annual rate of shoreline retreat has been -0, 97 m/y, which has established a total change of - 26 ± 7 m. The reduction in sand volumes has been -28 ± 8 m3/m, at a rate of -1,04 m3/m/y. In Santa Maria beach, the shoreline has experienced retreat in some localities or little change in the others. However, a remarkable increase in sand volumes of the emerged beach has taken place in all the cases. The reactivation of Aeolian processes, resulting in the reestablishment of dune morphology, was possible due to the removal of the Australian pine forest that had occupied the area from the beach top landward for more than 20 years.

This group is the best represented of cuban hydroids fauna of shallow waters. They are the 64 % of all known hydroids of Cuba and are composted by 11 families, 34 genera and 72 species. The 36% it is present in the Caribbean Sea, the 30 % are confined to the Atlántic Ocean, the 12,24 % are in the Pacific Ocean, the 7,2 % are registered for the Mediterránean Sea and the 5% are cosmopolitans. At present the Tecate fauna of Cuba is known mainly from the Western part of the Country and 13, 5 % are collected between 0 to 50 m.

    Beschreibung: The results of the application of the formula of Kawamura (1951) to in situ meteorological data in order to forecast the sand transport rate due to wind action are described in this paper. A new episode of dune formation started in the 1980's in these beaches, and more recently they have been affected by aeolian erosion since the beginning of the destruction of foredune vegetation due to the increase in tourist activities in the area. Shear velocity (U*t) values on the surface were determined starting from wind speed vertical profiles. Critical shear velocity values to start the sand movement were also determined, taking into account the grain size variations of the beach material along the coast. And finally, transport rates are calculated in each case. A comparison is carried out between the transport rates estimated starting from wind data and those resulting from meaurements of the sand volumes accumulated in the dunes during 12 years of monitoring. The main transport directions are shown, as well as the direction of the resultant and their relation to the morphological and dynamic pattern of the dunes. Besides, it is concluded that aeolian transport is limited to those sites where grain size is higher than 0.5 mm.

    Beschreibung: Estero Ciego beach is located in the tourist area in Holguín province, northeastern coast of Cuba. At present, the beach suffers an erosion process, being observed the appearance of extensive rocky surfaces in the eastern half of the beach as well as a marked deficit of sand in the coast. The objective of this study is to define the engineering solutions required to improve the aesthetic and use conditions of the beach. As main action it is proposed the artificial nourishment of sand, since it constitutes a solution that creates the aesthetic conditions rapidly. As a complement to guarantee the beach stability for a longer period of time, it is also intended to reduce part of the rocky surface that presently exists on the coastline in the eastern half of the beach.

    Beschreibung: The digitization of biodiversity data is leading to the widespread application of taxon names that are superfluous, ambiguous or incorrect, resulting in mismatched records and inflated species numbers. The ultimate consequences of misspelled names and bad taxonomy are erroneous scientific conclusions and faulty policy decisions. The lack of tools for correcting this ‘names problem’ has become a fundamental obstacle to integrating disparate data sources and advancing the progress of biodiversity science. The TNRS, or Taxonomic Name Resolution Service, is an online application for automated and user-supervised standardization of plant scientific names. The TNRS builds upon and extends existing open-source applications for name parsing and fuzzy matching. Names are standardized against multiple reference taxonomies, including the Missouri Botanical Garden's Tropicos database. Capable of processing thousands of names in a single operation, the TNRS parses and corrects misspelled names and authorities, standardizes variant spellings, and converts nomenclatural synonyms to accepted names. Family names can be included to increase match accuracy and resolve many types of homonyms. Partial matching of higher taxa combined with extraction of annotations, accession numbers and morphospecies allows the TNRS to standardize taxonomy across a broad range of active and legacy datasets. We show how the TNRS can resolve many forms of taxonomic semantic heterogeneity, correct spelling errors and eliminate spurious names. As a result, the TNRS can aid the integration of disparate biological datasets. Although the TNRS was developed to aid in standardizing plant names, its underlying algorithms and design can be extended to all organisms and nomenclatural codes. The TNRS is accessible via a web interface at http://tnrs.iplantcollaborative.org/ webcite and as a RESTful web service and application programming interface. Source code is available at https://github.com/iPlantCollaborativeOpenSource/TNRS/ webcite.

    Beschreibung: As biological disciplines extend into the ‘big data’ world, they will need a names-based infrastructure to index and interconnect distributed data. The infrastructure must have access to all names of all organisms if it is to manage all information. Those who compile lists of species hold different views as to the intellectual property rights that apply to the lists. This creates uncertainty that impedes the development of a much-needed infrastructure for sharing biological data in the digital world. The laws in the United States of America and European Union are consistent with the position that scientific names of organisms and their compilation in checklists, classifications or taxonomic revisions are not subject to copyright. Compilations of names, such as classifications or checklists, are not creative in the sense of copyright law. Many content providers desire credit for their efforts. A ‘blue list’ identifies elements of checklists, classifications and monographs to which intellectual property rights do not apply. To promote sharing, authors of taxonomic content, compilers, intermediaries, and aggregators should receive citable recognition for their contributions, with the greatest recognition being given to the originating authors. Mechanisms for achieving this are discussed.
