Se presenta el primer relevamiento de coleópteros acuáticos y semiacuáticos del Parque Provincial Ernesto Tornquist. El material entomológico estudiado se obtuvo durante las campañas de recolección ...de insectos acuáticos, realizadas entre los años 2005 y 2007, en las cuatro estaciones del año. Los ambientes estudiados fueron los arroyos Ventana, El Loro, Sauce Grande y dos charcos temporarios. Se identificaron en total 5.200 ejemplares pertenecientes a 9 familias, 20 géneros y 34 especies. Se brinda el listado de las especies y su distribución en la Argentina. Se citan, por primera vez para el parque, 23 especies y por primera vez para la Provincia de Buenos Aires: Austrelmis sp. e Hydrochus stolpi Germain. PALABRAS CLAVE. Coleoptera acuáticos. Inventario. Sierra de la Ventana. Argentina. Biodiversidad. We present the results of the first survey on the aquatic and semiaquatic water beetles from the Ernesto Tornquist Provincial Park. The material was obtained from several quantitative samplings of aquatic insects covering all seasons from 2005 to 2007. The surveyed habitats were the Ventana, El Loro and Sauce Grande streams and two rain pools. A total of 5,200 specimens belonging to 9 families, 20 genera and 34 species of Coleoptera were identified. A list of the species known to occur in the park along with their distributional data in Argentina is presented. Twenty-three species are cited from the park for the first time. Austrelmis sp. and Hydrochus stolpi Germain are recorded for the first time from Buenos Aires Province. KEY WORDS. Aquatic Coleoptera. Inventory. Sierra de la Ventana. Argentina. Biodiversity.
Using a Heckscher-Ohlin model, this paper studies how growing international trade, disadvantageous to unskilled labour, affects an industrialised economy characterised by downward stickiness of ...certain real wages, resulting in unemployment of the workers concerned. We consider whether such an economy is more vulnerable to this form of international trade than a economy without rigidities, especially with regard to the pattern of national income, real income and employment of workers a priori protected by these rigidities. We also study the impact of international capital mobility on the pattern of these variables .
Dans un cadre à la Hecscher-Ohlin, cet article étudie comment un commerce international croissant, défavorable au travail peu qualifié, affecte une économie industrialisée caractérisée par une rigidité à la baisse de certains salaires réels entraînant du chômage chez les travailleurs concernés. Nous examinons si une telle économie est plus vulnérable à cette forme de commerce international qu''une économie sans rigidité, en particulier en ce qui concerne l'évolution du revenu national et celle du revenu réel et de l'emploi des travailleurs a priori protégés par ces rigidités. Nous étudions en outre l’incidence de la mobilité internationale des capitaux sur l’évolution de ces variables.
