  • Diet Composition of Lysapsus Bolivianus Gallardo, 1961 (Anura, Hylidae) of the Curiaú Environmental Protection Area in the Amazonas River Estuary
    Herpetology Notes, volume 13: 113-123 (2020) (published online on 11 February 2020) Diet composition of Lysapsus bolivianus Gallardo, 1961 (Anura, Hylidae) of the Curiaú Environmental Protection Area in the Amazonas river estuary Mayara F. M. Furtado1 and Carlos E. Costa-Campos1,* Abstract. Information on a species’ diet is important to determine habitat conditions and resources and to assess the effect of preys on the species distribution. The present study aimed describing the diet of Lysapsus bolivianus in the floodplain of the Curiaú Environmental Protection Area. Individuals of L. bolivianus were collected by visual search in the floodplain of the Curiaú River. A total of 60 specimens of L. bolivianus were euthanized with 2% lidocaine, weighed, and their stomachs were removed for diet analysis. A total of 3.020 prey items were recorded in the diet. The most representative preys were: Diptera (36.21%), Collembola (16.61%), and Hemiptera (8.31%), representing 73.20% of the total consumed prey. Based on the Index of Relative Importance for males, females, and juveniles, the most important items in the diet were Diptera and Collembola. The richness of preys recorded in the diet of L. bolivianus in the dry season was lower than that of the rainy season. Regarding prey abundance and richness, L. bolivianus can be considered a generalist species and a passive forager, with a diet dependent on the availability of preys in the environment. Keywords. Amphibia; Eastern Amazon, Niche overlap, Predation, Prey diversity, Pseudinae Introduction (Toft 1980; 1981; Donnelly, 1991; López et al., 2009; López et al., 2015). The diet of most anuran species is composed mainly of The genus Lysapsus Cope, 1862 is restricted to South arthropods and because of the opportunistic behaviour of America and comprises aquatic and semi-aquatic anurans many species, anurans are usually regarded as generalist inhabiting temporary or permanent ponds with large predators (Duellman and Trueb, 1994).

Earlier indices developed for Argentina (Velázquez, 2008; 2010a) provided basically two dimensions: a) socio-economic and b) environmental. Socio-economic dimension embraces such indicators as education, health and housing, while environmental one considers three aspects: nature-based recreational resources, socially constructed recreational resources and environmental problems.

  • The Larva of Mecistogaster Amalia (Odonata: Pseudostigmatidae)
    Received 04 June 2009; revised and accepted 09 September 2009 The larva of Mecistogaster amalia (Odonata: Pseudostigmatidae) Javier Muz6n, Soledad Weigel Munoz & Raul Ernesto Campos lnstituto de Limnologfa "Dr. R.A. Ringuelet'; (CONICET- CCT La Plata), C.C. 712, 1900, La Plata, Argentina. <[email protected]> Key words: Odonata, dragonfly, Mecistogaster amalia, Pseudostigmatidae, larva, phytotelmata. ABSTRACT The final larval stadium of Mecistogaster amalia is described and illustrated for the first time based on one female collected in a tree hole in Misiones province, Argen­ tina, and compared with all known larvae of related genera. Larval morphology of Pseudostigmatidae is briefly discussed. INTRODUCTION Pseudostigmatidae include 17 species in five neotropical genera, i.e. Anomisma McLachlan, 1877, Mecistogaster Rambur, 1842, Megaloprepus Rambur, 1842, Microstigma Rambur, 1842, and Pseudostigma Selys, 1860. This family includes the longest species in the order Odonata, all of which as far as known breed exclu­ sively in phytotelmata as does its East African sister group Coryphagrion grandis Morton, 1924 (Corbet 1999: 145; Clausnitzer & Lindeboom 2002; Fincke 2005; Groeneveld et al. 2007). Final stadium larvae of Mecistogaster linearis (Fabricius, 1776), M. modesta Se­ lys, 1860, M. ornata Rambur, 1842, M. asticta Selys, 1860, Microstigma rotunda­ tum Selys, 1860, M. maculatum Hagen in Selys, 1860, Megaloprepus caerulatus (Drury, 1782), and Pseudostigma aberrans Selys, 1860 have been described so far (Calvert 1911; Novelo Gutierrez 1993; Ramirez 1995, 1997; Westfall & May 1996; Hedstrom & Sahlen 2003; Sahlen & Hedstrom, 2005; Lencioni 2006; De Marmels 2007; Neiss et al. 2008).

    ARGENTINA’S INFORMAL ECONOMY: A CASE STUDY OF PATRIA GRANDE UPON THE INFORMAL TEXTILE INDUSTRY A Thesis submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Masters of Arts in Development Management and Policy By Anna Porembka, B.A. Washington, DC May 1, 2013 Copyright 2013 by Anna Porembka All Rights Reserved ii ARGENTINA’S INFORMAL ECONOMY: A CASE STUDY OF PATRIA GRANDE UPON THE INFORMAL TEXTILE INDUSTRY Anna Porembka, B.A. Thesis Advisor: Matthew Carnes, S.J. ABSTRACT In order to strengthen their economic positions, developing nations like Argentina have produced laws aimed at salient informal manifestations. Argentina’s 2005 law “Patria Grande” sought to answer public outcry after a deadly fire exposed the inhumane conditions of illegal textile workers. What is the relationship between public policy and informality, and what legal, economic, and social characteristics identify the informal economy generally, and in Argentina specifically? What is the historical foundation of Argentine informality, and how has it behaved in the 21st century? Finally, how did Patria Grande develop, and what lessons can we learn from its results? By taking a public policy approach to informality, this study unravels the current characteristics and the historical roots of Argentina’s institution of informality. Three empirically recognized factors of informality are applied in a MIMC model and discussed with regard to Argentina’s history and present condition. These indicators support that, since the 2001-2 crisis, the Argentine informal economy appears to be shrinking, but at a decreasing rate.

  • Ecology of <I>Lysapsus Limellum</I> in the Brazilian Amazon River Basin
    HERPETOLOGICAL JOURNAL 17: 141–148, 2007 Ecology of Lysapsus limellum in the Brazilian Amazon river basin Adrian Antonio Garda1, Gabriel Correa Costa1, Frederico Gustavo Rodrigues França2 & Daniel Oliveira Mesquita2 1Sam Noble Oklahoma Museum of Natural History and Department of Zoology, University of Oklahoma, Norman, OK, USA 2Departamento de Zoologia, Universidade de Brasília, Brasília, DF, Brazil Lysapsus currently comprises three species distributed east of the Andes, from Guyana to northern Argentina. Lysapsus limellum occurs along the Amazon and Paraná river basins in ponds associated with river floodplains. We analyse geographic distribution, diet, reproduction, habitat use and diel activity of L. limellum from several populations in the Brazilian Amazon. Wide floodplains and open areas are common features of habitats of L. limellum, and populations are found either in savanna fragments or in floodplains along the Amazon river and its major tributaries. In savanna fragments of Humaitá, Amazonas, L. limellum is active during day and night and prefers areas with floating vegetation only. Frogs are active and prone to move during the day but remain motionless and call more at night. Most important diet items were dipterans, hemipterans/homopterans and odonates, underscoring the generalist behaviour of the species and its particular preference for dipterans. Females were significantly larger than males, but females and males were not different in shape. Neither number nor volume of eggs was related to female snout–urostyle length (SUL), while testis volume was significantly related to male SUL. In summary, L. limellum is a widely distributed small aquatic frog with a generalist diet that inhabits ponds in open floodplains.

  • Ireland and Latin America: a Cultural History
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2010 Ireland and Latin America: a cultural history Murray, Edmundo Abstract: According to Declan Kiberd, “postcolonial writing does not begin only when the occupier withdraws: rather it is initiated at that very moment when a native writer formulates a text committed to cultural resistance.” The Irish in Latin America – a continent emerging from indigenous cultures, colonisation, and migrations – may be regarded as colonised in Ireland and as colonisers in their new home. They are a counterexample to the standard pattern of identities in the major English-speaking destinations of the Irish Diaspora. Using literary sources, the press, correspondence, music, sports, and other cultural representations, in this thesis I search the attitudes and shared values signifying identities among the immigrants and their families. Their fragmentary and wide-ranging cultures provide a rich context to study the protean process of adaptation to, or rejection of, the new countries. Evolving from oppressed to oppressors, the Irish in Latin America swiftly became ingleses. Subsequently, in order to join the local middle classes they became vaqueros, llaneros, huasos, and gauchos so they could show signs of their effective integration to the native culture, as seen by the Latin American elites. Eventually, some Irish groups separated from the English mainstream culture and shaped their own community negotiating among Irishness, Englishness, and local identities in Brazil, Uruguay, Peru, Cuba, and other places in the region. These identities were not only unmoored in the emigrants’ minds but also manoeuvred by the political needs of community and religious leaders.

    DREF operation n° MDRAR006 Argentina: Floods Glide No.FL-2009-000254-ARG 9 August 2010 The International Federation’s Disaster Relief Emergency Fund (DREF) is a source of un-earmarked money created by the Federation in 1985 to ensure that immediate financial support is available for Red Cross Red Crescent response to emergencies. The DREF is a vital part of the International Federation’s disaster response system and increases the ability of National Societies to respond to disasters. Summary: 230,629 Swiss francs (229,848 US dollars/152,957 euro) were allocated from the Federation’s Disaster Relief Emergency Fund (DREF) on 3 December 2009 to support the Argentine Red Cross (ARC) in delivering assistance to some 944 families. On 23 November 2009, heavy rains affected the north-eastern provinces of Chaco, Corrientes, Misiones, Entre Rios, Santa Fe, north-eastern Salta and Formosa with floods. The Argentine Red Cross branches in the affected areas reached 30,618 people (4,374 families) with essential relief items including dengue prevention kits, hygiene kits, cleaning kits, kitchen sets, water and sanitation kits and bedding kits. The assistance also included hygiene Argentine Red Cross volunteers conducted a distribution of food items in promotion campaigns and Concordia in the province of Entre Rios.

  • Vulnerability of the Agricultural Systems of Argentina to Climate Change
    CLIMATE RESEARCH Published December 29 Clim Res Vulnerability of the agricultural systems of Argentina to climate change Graciela 0. Magrin*,Maria I. Travasso, Raul A. Diaz, Rafael 0.Rodriguez Instituto de Clima y Agua, Centro de Investigaciones en Recursos Naturales, Instituto Nacional de Tecnologia Agropecuaria, 1712 Castelar, Buenos Aires. Argentina ABSTRACT: Agricultural production is one of the pillars of the Argentinean economy. The contribution of this sector is expected to keep growing in the near future as a consequence of the current techno- logical development trend. However, the projected changes in climate and in the atmospheric concen- tration of CO2in the coming years is likely to affect the productivity of crops, thus causing an impact on the national economy. This paper addresses climate change impact on the production of the main crops of the Argentinean pampean region by means of crop growth and development simulation models for wheat, maize and soybean included in DSSAT v. 3.0 (Dension Support System for Agrotechnology Transfer, Univ. of Hawaii, Honolulu). The weather data used includes temperature, global solar radia- tion and precipitation values from 23 sites within the region (current climate conditions) and the corre- sponding GISS general circulation model projections for the year 2050 (future climate) with CO2 con- centrations of 330 and 550 ppm respectively. According to the results obtained, a generalized increase In soybean yield and a decrease in maize yield would occur. Wheat yield is likely to increase in the southern and the western parts of the region and decrease towards the north. Wheat and soybean pro- duction in the pampean region would increase by 3.6 and 20.7 % respectively, while maize production would be reduced by 16.5%.
