Marine Biodiversity in the Caribbean: Regional Estimates and Distribution Patterns
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
Memoria del II Coloquio Internacional sobre Diversidad Cultural y Estudios Regionales
Desde la Sede de Occidente y, especĂficamente, en el seno de la CoordinaciĂłn de InvestigaciĂłn y con el apoyo de la DirecciĂłn de la Sede y las Coordinaciones de Docencia, AdministraciĂłn y AcciĂłn Social, asĂ como de la VicerrectorĂa de InvestigaciĂłn, se han celebrado en el 2011 y en el 2012 dos coloquios internacionales sobre diversidad cultural y estudios regionales. El propĂłsito de ambos consistiĂł principalmente en motivar a investigadores e investigadoras de las distintas unidades acadĂ©micas de la Universidad de Costa Rica y de otras instituciones de EducaciĂłn Superior, asĂ como a representantes de Centros e Institutos de InvestigaciĂłn nacionales e internacionales, a presentar resultados de investigaciones que contribuyeran a un mayor conocimiento de los procesos culturales y que dieran a conocer resultados que permitieran la comprensiĂłn de las realidades de distintos sectores y regiones. En el 2011 se presentaron cuarenta y seis ponencias y se dictaron tres conferencias magistrales, y en el 2012 se expusieron cincuenta ponencias y se impartieron tres conferencias magistrales.UCR::Sedes Regionales::Sede de Occidente::Recinto San RamĂłn::Centro de Investigaciones sobre Diversidad Cultural y Estudios Regionales (CIDICER
El estudio de las aves en Guayabetal y Soacha – Cundinamarca-, un aporte a la conservación de los ecosistemas.
Desde la practica educativa en el área de ciencias naturales y educaciĂłn ambiental, con estudiantes del municipio de Guayabetal y Soacha, se realiza un trabajo de concientizaciĂłn en la conservaciĂłn del habitad de las aves, estudiando las caracterĂsticas principales de ellas. Encontramos cinco capĂtulos.
Articulando el trabajo del PRAE (proyectos ambientales escolares) con el plan de desarrollo turĂstico del municipio. El planteamiento del problema que define las necesidades y los daños en estos ecosistemas, los objetivos, determinan el alcance de este estudio. Los antecedentes que muestran los intereses del cuidado del ambiente. Un marco teĂłrico donde podemos encontrar el contexto de las instituciones educativas, la ornitologĂa y el marco legal de PRAE y la importancia de los AVA (ambientes virtuales de aprendizaje). La metodologĂa que establece el mĂ©todo de investigaciĂłn tomando el modelo ADDIE.
Se identificaron las aves más representativas (12), diseñando el recurso educativo tecnolĂłgico a usar (página wix) con cinco pantallas donde se evidencian las caracterĂsticas generales de las aves, tres grupos de aves (orden), paseriformes, apodiformes y gruiformes y una página de evaluaciĂłn del contenido, con un alto contenido de videos, imágenes y audios de las especies en menciĂłn.
Siendo sometido este recurso a una evaluaciĂłn de validaciĂłn por parte de profesionales y docentes. Donde tuvo una amplia acogida.From the educational practice in the area of natural sciences and environmental education, with students from the municipality of Guayabetal and Soacha, an awareness work is carried out in the conservation of the habitat of the birds, studying the main characteristics of them.
We found five chapters.
Articulating the work of the PRAE (school environmental projects) with the tourism development plan of the municipality. The problem statement that defines the needs and damages in these ecosystems, the objectives, determine the scope of this study. The background that shows the interests of environmental care. A theoretical framework where we can find the context of educational institutions, ornithology and the legal framework of PRAE and the importance of VPAs (virtual learning environments). The methodology established by the research method taking the ADDIE model.
The most representative birds were identified (12), designing the technological educational resource to be used (wix page) with five screens showing the general characteristics of the birds, three groups of birds (order), passerine, apodiform and gruiform and one page Content evaluation, with a high content of videos, images and audios of the species in question.
This resource being submitted to a validation evaluation by professionals and teachers. Where this had a wide reception.1. IntroducciĂłn. – 2. Planteamiento del problema. – 3. Problemática. – 4.

Make EU trade with Brazil sustainable
Brazil, home to one of the planet's last great forests, is currently in trade negotiations with its second largest trading partner, the European Union (EU). We urge the EU to seize this critical opportunity to ensure that Brazil protects human rights and the environment
