[EN]This paper undertakes the study of the occurrence of non-corresponding demonstrative forms in Spanish, Basque and English in exactly the same linguistic context. It is proposed that the differenccs in the choice of the demonstratives result from the differences in the kind of iniormation that must be coded in each of the languages. Thus, I will argue that in Spanish and Basque the obligatory coding of the aspectual categories of the imperfect and the preterit has the function of imposing specific viewing arrangements onto the situations they designate. By contrast, in English, where the aspectual distinction is not overtly coded, the demonstrativcs are proposed to fulfil this function.

El presente trabajo aporta información de base para el seguimiento y evaluación de la biodiversidad de las aves a escala local o regional. Para la realización de la lista, hemos tenido como punto de referencia la Lista sistemática de las aves de la provincia de Buenos Aires de N. Bó y C. Darrieu 1991 y Las aves de la provincia de Buenos Aires: distribución y estatus de T. Narosky y A. Di Giácomo 1993. La presente enumeración considera todas las especies de aves que habitan la provincia de Buenos Aires, es decir aquellas que nidifican o que pasan gran parte del año en la misma. Se excluyen, por lo tanto, aquellas especies accidentales y ocasionales. Los datos se basan en citas bibliográficas recientes, material de colección y observaciones de campo realizadas por los autores. Para indicar la distribución geográfica de las aves se ha seguido el esquema propuesto por Ringuelet y Arámburu (1957, Enumeración sistemática de los Vertebrados de la Provincia de Buenos Aires). Según el mismo se divide a la provincia en cuatro áreas: la 1 posee una avifauna de tipo subtropical; en la 2 se encuentran aves pampeanas con ingresión de especies de la Provincia Chaqueña (Distrito Occidental); en la 4 la avifauna presenta un gran número de especies que llegan por el sur desde la Provincia del Monte (Distrito Meridional) y de la Provincia Patagónica (Distrito Occidental); el área 3 es de transición con aporte de especies de las otras zonas. La presente lista comprende los nombres científicos tomados de Altman & Swift (1989), Checklist of the Birds of South America. Para los nombres vulgares se siguió a Navas et al (1991). Lista Patrón de Nombres Comunes de las Aves Argentinas. Se incluye además una lista de las especies exóticas naturalizadas. (Text is in Spanish.

Water chestnut (Trapa natans L.,sensu lato) is an annual, floating-leaved aquatic plant of temperate and tropical freshwater wetlands, rivers, lakes, ponds, and estuaries. Native to Eurasia and Africa, water chestnut has been widely gathered for its large nutritious seed since the Neolithic and is cultivated for food in Asia. Water chestnut is now a species of conservation concern in Europe and Russia. Introduced to the northeastern United States in the mid-1800s, the spread of water chestnut as a nuisance weed was apparently favored by cultural eutrophication. Water chestnut is considered a pest in the U.S. because it forms extensive, dense beds in lakes, rivers, and freshwater-tidal habitats.

[ES]En los últimos años, la baja participación de la mujer y la tendencia al descenso de los porcentajes de alumnas matriculadas en los estudios universitarios de informática ha sido objeto de estudio para investigadoras/es en Estados Unidos, Europa y otros países. Habiendo constatado también en la Facultad de Informática de San Sebastián (FISS) de la Universidad del País Vasco (UPV/EHU) dicho descenso, nuestro objetivo ha sido recopilar información estadística para determinar si esta tendencia se ha producido también en otras universidades del Estado español. El estudio incluye, en primer lugar,porcentajes de mujeres inscritas en Ingeniería Informática comparados con los porcentajes en el área técnica en su conjunto. Por otra parte, recoge datos del tercer ciclo y porcentajes de profesoras de los departamentos que imparten docencia en la FISS, comparados con los porcentajes en los mismos departamentos en el conjunto del Estado. Por último, se presentan datos de inserción en el mundo laboral para las promociones 1998-2002 de egresadas/os en la UPV/EHU. Los datos revelan los bajos porcentajes de mujeres que se han matriculado en Ingeniería Informática los últimos años y la tendencia al descenso, las diferencias entre distintas universidades,y que apenas hay sesgo de género en los datos de inserción en el mundo laboral.

The term “fishery resources” is used in this book with a broad application. It includes the populations of the fishes and other organisms useful to men, the environment that makes life possible for them, the industry that exploits and utilizes them, and our knowledge about them by which we can conserve their productivity. This book aims to survey the present status of all these aspects of those fishery resources that are used or are available for use by United States anglers and commercial fishermen. It is planned primarily for the Congress, at its request, with the idea of giving to busy people, in condensed fashion, a perspective on its subject. (pdf contains 142 pages)

Water bodies located at 34º 58' S, 62º 58' W formed after 1980 by 30 % increasing rainfall during the last half century, were colonized by ten fish species which are a subset of the commonest species living in the pampasic lagunas. These new populations imply a displacement of the West of Pampasian fishes to areas of the western basins previously lacking fish.

Understanding how well National Marine Sanctuaries and other marine protected areas represent the diversity of species present within and among the biogeographic regions where they occur is essential for assessing their conservation value and identifying gaps in the protection of biological diversity. One of the first steps in any such assessment should be the development of clearly defined and scientifically justified planning boundaries representing distinct oceanographic conditions and faunal assemblages. Here, we propose a set of boundaries for the continental shelf of northeastern North America defined by subdivisions of the Eastern Temperate Province, based on a review and synthesis (i.e. meta-analysis) of the scientific literature. According to this review, the Eastern Temperate Province is generally divided into the Acadian and Virginian Subprovinces. Broad agreement places the Scotian Shelf, Gulf of Maine, and Bay of Fundy within the Acadian Subprovince. The proper association of Georges Bank is less clear; some investigators consider it part of the Acadian and others part of the Virginian. Disparate perspectives emerge from the analysis of different groups of organisms. Further, while some studies suggest a distinction between the Southern New England shelf and the rest of the Mid-Atlantic Bight, others describe the region as a broad transition zone with no unique characteristics of its own. We suggest there exists sufficient evidence to consider the Scotian Shelf, Gulf of Maine, Georges Bank, Southern New England, and Southern Mid-Atlantic Bight as distinct biogeographic regions from a conservation planning perspective, and present a set of proposed mapped boundaries.

A workshop was held 3-5 October 2002 in Gainesville, Florida, USA to discuss management, conservation and trade in Caiman yacare. Twenty five official participants represented the four yacare range states (Argentina, Bolivia, Brazil, Paraguay), Venezuela, USA, the meeting sponsors (US Fish and Wildlife Service, CITES Secretariat, Louisiana Fur and Alligator Council), TRAFFIC Sur America and Crocodile Specialist Group. A series of country reports detailing yacare management in the four range states were distributed in Spanish and English prior to the meeting and presentations on these and on general principles of crocodilian harvest, conservation and management provided the basis for the discussions. Three working groups considered: • Requirements and field techniques for field data collection. • Requirements and techniques for regulation of harvest. • Requirements and processes for regulation of trade and export. Written reports of working groups and a plenary drafting session were finalized during the meeting and distributed, with the country reports, to participants. The workshop drafted a framework for caiman management and regulation that could be used as a template and adapted for use in each range state. The meeting agreed to convene an ad-hoc working group of range state representatives to continue discussions on the harmonization of caiman management into the future.
