In this present study macro benthos of minicoy island lakshadweep, an attempt has been made to study the distribution and community structure of benthos at different ecosystems. The main objectives of the study include the identification of benthic fauna, their distribution and composition, standing stock, qualitative and quantitative nature in relation to hydrography,seasons and sediment texture, community structure analysis and tropic relationships. This base line study at Minicoy,thus establishes that the benthos of sea grass and mangrove ecosystems(nursery grounds) determines the richness and diversity of demersal fish fauna at the nearby lagoon and reef areas to a great extent. Any serious stress on these ecosystems may lead to disappearance of certain fish species in the nearby future

The tiniest Union territory of India, Lakshadweep, is an archipelago, with an area of 32 Sq. km. consisting of 12 atolls, three reefs and five submerged banks, lies between 8° and 12°30'N latitudes and 71° and 74" E longitudes. It is one of the most important and critical territories of India from economic and defence point of view. Specialised environment having typical geological set up, Lakshadweep is ecologically sensitive to even slight climatic or anthropogenic interference. Pollution of coastal seas, over exploitation and contamination of the fresh water sources are thus become great concerns to the existence of the island. Typical geological set up and interference cause threat to the ecology of the fragile environment and resources of the island as well as its resources. Marine pollution and ground water contamination are concerns in this regard. Even though attentions were made to assess the physico—chemical and bacteriological status of the marine and groundwater systems separately, an integrated approach has not been evolved. The present study with its broad objectives is attempted for an integrated assessment of microbiological, physicochemical and biological characteristics of the surrounding seawater and microbiological and physico—chemical characteristics of the ground water in Kavaratti island. The entire study has been organised in 4 chapters

Assessment water’ quality nowa-days in global scenario implies the need for a reference point against which monitoring can be measured and weighed. Aquatic ecosystenis as part of the natural environment are balanced both witliin tlicinselves and with other environmental compartments and this equilibrium is subject to natural variations and evolutions as well as variations caused by human intervention. The present assessnient is to identify. and possibly quantify, anthropogenic influences over time against a “natural baseline situation. Water pollution problems have only recently been taken seriously in retrospect. Once damage occurred, it becomes immeasurable, and control action cannot be initiated

El proyecto arranca de una idea central que consiste en programar todas las clases de inglés que correspondan a los dos ciclos de la ESO, partiendo de dos realidades culturales, como son: -la isla en la que vive el alumno con sus implicaciones en la región 'I shall show you my island'. -El lugar donde se habla la lengua, objeto de aprendizaje (inglés) 'You will show me your country'. El grupo de trabajo está compuesto por 19 docentes tanto de EGB como de bachillerato, y pertenecen a la isla de La Palma todos ellos. El objetivo general que se propone es lograr desarrollar las capacidades de los alumnos en los ámbitos cognitivos, afectivos y sociales tomando como base para su logro las vivencias que el medio en que se desarrollan les son consustanciales con su propia vida. Desde un principio se propuso llevar a cabo una unidad didáctica conectada al 'proyecto general', de tal manera que fuese coherente y siguiese una línea general y espiral con el resto de las once unidades restantes que forman en su conjunto todo el proyecto de enseñanza de la ESO. La unidad didáctica como un 'todo' organizado no se ha llevado a la práctica este curso, sin embargo a medida que se iba elaborando material, se iba investigando en el aula. Además de la aportación de la asesora de inglés, este trabajo se ha apoyado en: libros de texto, revistas pedagógicas, material de reprografía, medios informáticos, etc. En cuanto a la valoración del proyecto ha sido muy positiva tanto por el propio grupo de trabajo como por el público asistente a las Jornadas de Innovación celebradas en La Palma y donde pudo presentarse la experiencia..

This document examines, bases on the analysis of observable characteristics, if an income gapexists between the raizal population and non raizal population of San Andres Island. For thispurpose, the information of the SISBEN II survey for the year 2004, compelled by the NationalPlanning Department (DNP, Spanish acronym) is used. The methodological strategy uses quantileregressions to determine the existence of pay gaps throughout the distribution of income. Theresults suggest that being raizal has a negative impact on income for the lower quantiles. However,this difference vanishes as income increases, becoming positive at higher levels.

El autor hace un detallado recorrido por el mundo de los videojuegos desde los primeros modelos hasta la actualidad para darnos a conocer, entre otros, los videojuegos narrativos. Siendo la repetición una de las características típicas de los videojuegos, es através de ella que los niños pueden aprender bien en sentido positivo: superación del fracaso, perseverancia, etcétera; bien en sentido negativo: sexismo, capitalismo ambicioso, etcétera.

Pertenece a un amplio programa infantil de lectura que abarca distintos niveles de edad y, por tanto, de conocimientos. Se abordan las necesidades de lectura en los niños y la amplia variedad de habilidades que necesitan adquirir para su aprendizaje y, se destaca, también, la importancia de la narración en las historias. Aparecen dos nuevos personajes, Nadim y Anneena, que junto con Biff, Chip y Kipper colaboran para evitar la contaminación de la isla verde.

This paper examines the Rhode Island Test of Language Structures (RITLS) and its measurement of the comprehension of syntax, and the relationship of this comprehension to the use of syntax in the production of spoken English by orally educated hearing-impaired students.

Breeding seabirds are threatened by human activities that affect nesting and foraging habitat. In Canada, one of the seabirds most at risk of extirpation is the Roseate Tern, Sterna dougallii. Although critical nesting habitat has been identified for the Roseate Tern in Canada, its foraging locations and the diet of its chicks are unknown. Therefore, our goal was to determine the foraging locations and diet of chicks of Roseate Tern breeding on Country Island, Nova Scotia, which is one of Canada's two main breeding colonies. In 2003 and 2004, we radio-tracked the Roseate Tern by plane to locate foraging areas and conducted feeding watches to determine the diet of chicks. Roseate Tern foraged approximately 7 km from the breeding colony over shallow water < 5 m deep. In both years, sand lance, Ammodytes spp., was the most common prey item delivered to chicks, followed by hake, Urophycis spp. Our results are consistent with previous work at colonies in the northeastern United States, suggesting that throughout its range, this species may be restricted in both habitat use and prey selection. The reliance on a specific habitat type and narrow range of prey species makes the Roseate Tern generally susceptible to habitat perturbations and reductions in the availability of prey.
