A preliminary revision of knowledge status of felids in Argentina Mastozool. neotrop.
Lucherini,Mauro; Soler,Lucía; Luengos Vidal,Estela.
Argentina is the host of 10 wild felids (28% of the world total). Although the Cat Specialist Group Action Plan has classified the conservation status of Argentine cats as relatively good, the ranking was based on a largely incomplete database for at least 80% of the species. Here we review the current status of knowledge and research effort of Argentine cats, compare it with their distribution, habitat association and conservation status and provide guidelines for their future research. Between 1990 and 2000, cat research has received increasing attention in Argentina. Twenty-four projects have been carried out, but only 13 studies are still in progress. A rank of research priority has been calculated for each felid and ecoregion. Our analysis showed that...

A Scientometric view of some Biological disciplines in Chile Biol. Res.
KRAUSKOPF,MANUEL.
During the last decade the articles published by Chilean Research Centers grew 1,73 which compares to the 2.34 fold increase of mainstream research articles registered as a whole in Latin America. However, the relative impact of the Chilean publications surpassed that of Latin America. In Biological Sciences, traditionally the strongest research area within Chile, Latin America also shows a steeper slope of growth. Qualitatively, biological disciplines in Chile are comparable to those published in Latin America although in Chile there are specialties as Physiology that surpass the average world's impact. The scientometric data is consistent with the fall in individual grants that the Chilean Research Fund (FONDECYT) has been allocating during the last...

Activity of ceftaroline and comparators against pathogens isolated from skin and soft tissue infections in Latin America - results of AWARE surveillance 2012 BJID
Hoban,Daryl; Biedenbach,Douglas; Sahm,Daniel; Reiszner,Edina; Iaconis,Joseph.
ABSTRACT As part of the Assessing Worldwide Antimicrobial Resistance Evaluation (AWARE) surveillance program in 2012 the in vitro activity of ceftaroline and relevant comparator antimicrobials was evaluated in six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico and Venezuela) against pathogens isolated from patients with hospital associated skin and soft tissue infections (SSTIs). The study documented that ceftaroline was highly active (MIC90 0.25 mg/L/% susceptible 100%) against methicillin-susceptible Staphylococcus aureus, methicillin-resistant S. aureus (MIC90 2 mg/L/% susceptible 83.3%) and ß-hemolytic streptococci (MIC90 0.008-0.015 mg/L/% susceptible 100%). The activity of ceftaroline against selected species of...

Adapting prospective structural analysis to strengthen sustainable management and capacity building in community-based natural resource management contexts Ecology and Society
Local communities collectively managing common pool resources can play an important role in sustainable management, but they often lack the skills and context-specific tools required for such management. The complex dynamics of social-ecological systems (SES), the need for management capacities, and communities’ limited empowerment and participation skills present challenges for community-based natural resource management (CBNRM) strategies. We analyzed the applicability of prospective structural analysis (PSA), a strategic foresight tool, to support decision making and to foster sustainable management and capacity building in CBNRM contexts and the modifications necessary to use the tool in such contexts. By testing PSA in three SES in Colombia,...

Agricultural Export Diversification in Latin America and the Caribbean AgEcon
Taylor, Timothy G.; Francis, Brian.
Agriculture, in general, and agricultural exports in particular, have long been critical to economic growth and development in Latin America and the Caribbean (LAC). Despite the importance of agriculture to the region and the vast amount of resources devoted to the promotion of agricultural export diversification in LAC, there has been virtually no research undertaken to assess the degree to which the agricultural export structures in LAC countries have in fact diversified. Using disaggregate data on agricultural exports over the 1961-2000 period for 10 LAC countries, entropy-based measures of diversification are computed and analyzed. The empirical results show that the post-1985 period has witnessed some degree of agricultural export diversification...

An Analysis of Latin American Peanut Trade AgEcon
Lee, Dae-Seob; Kennedy, P. Lynn; Fletcher, Stanley M..
The U.S. export share in the world peanut market has decreased due to heavy competition. In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR). Based on these estimations, a scenario analysis was conducted. The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks. The effects of price changes on net trade are noticeable. However, the world price does not significantly affect the Latin American peanut supply. The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

An outbreak of Candida spp. bloodstream infection in a tertiary care center in Bogotá, Colombia BJID
DiazGranados,Carlos A.; Martinez,Adriana; Deaza,Ceneth; Valderrama,Sandra.
Several cases of Candida bloodstream infections were documented from June to October 2004 at a tertiary care center in Bogotá, Colombia. Since no cases of candidemia had occurred during the preceding four months, an outbreak was declared. As a result, a microbiological study, a revision of infection control practices and a case-control study were performed. In all, 18 cases of candidemia were ascertained. Parenteral nutrition (p=0.04), presence of a central line (p=0.03), and severity of illness (p=0.03) were associated with candidemia in bivariate analysis. Diverse Candida species were observed. Candida parapsilosis contamination was found in plastic containers used for transient intravenous (IV) medication storage at the bedside, plastic bags reused for...

Ancestral genetic composition of a human population from the Colombian southwest using autosomal AIM-InDels JBAG
Urbano,L; Portilla,E.C; Builes,J.J; Gusmão,L; Sierra-Torres,C.H.
Genetic markers with allele distribution differences in human populations provide human ancestry information that can be used to evaluate admixture proportions in different ethnic groups, including stratification in genetic association studies. The aim of this study was to determine the African, European and Native American admixture proportion by making use of 46 insertion-deletion informative ancestry record markers set in 500 Latin American people in the Department of Cauca, Colombia. Allelic frequencies were established, Hardy Weinberg test was performed, comparisons in genetic distances among population groups were estimated using Arlequin v 3.5, and STRUCTURE v 2.3.4 software was used to determine the population’s ancestry admixture. The...

Mendes,C.; Marin,M. E.; Quiñones,F.; Sifuentes-Osornio,J.; Cuilty Siller,C.; Castanheira,M.; Zoccoli,C. M.; López,H.; Súcari,A.; Rossi,F.; Barriga Angulo,G.; Segura,A.J.A.; Starling,C.; Mimica,I.; Felmingham,D..
PROTEKT (Prospective Resistant Organism Tracking and Epidemiology for the Ketolide Telithromycin) is a global surveillance study established in 1999 to monitor antibacterial resistance of respiratory tract organisms. Thirteen centers from Argentina, Brazil and Mexico participat ed during 1999-2000; they collected 1,806 isolates (Streptococcus pneumoniae 518, Haemophilus influenzae 520, Moraxella catarrhalis 140, Staphylococcus aureus 351, S. pyogenes 277). Overall, 218 (42.1%) of the S. pneumoniae isolates had reduced susceptibility to penicillin, 79 (15.3%) were penicillin-resistant and 79 (15.3%) were erythromycin-resistant. Mexico had the highest prevalence of penicillin (76.5%) and erythromycin (31.2%) resistance. Of 77 erythromycin-resistant S....

Assessing the Sustainability of Small Farmer Natural Resource Management Systems. A Critical Analysis of the MESMIS Program (1995-2010) Ecology and Society
Sustainability assessment oriented to improve current systems and practices is urgently needed, particularly in the context of small farmer natural resource management systems (NRMS). Unfortunately, social-ecological systems (SES) theory, sustainability evaluation frameworks, and assessment methods are still foreign not only to farmers but to many researchers, students, NGOs, policy makers/operators, and other interested groups. In this paper we examine the main achievements and challenges of the MESMIS Program (Spanish acronym for Indicator-based Sustainability Assessment Framework), a 15-year ongoing effort with impact in 60 case studies and 20 undergraduate and graduate programs mainly in Ibero-America that is attempting to cope with the stated...

Atlas of Organics: Four maps of the world of organic agriculture Organic Eprints
Paull, John; Hennig, Benjamin.
This paper presents four maps of the world of organic agriculture. Density equalising maps (cartograms) have previously been published of the world of organic agriculture based on the reported hectares of certified organically managed agriculture land. The four maps in the present atlas of organic agriculture are visual presentations of current global organics data: (a) certified organic agriculture hectares; (b) certified organic wildculture hectares; (c) total certified organic production hectares (organic agriculture plus wildculture plus forestry plus aquaculture); (d) certified organic producers. Australia dominates in the world map of the organic agriculture hectares, Europe is strongly represented, and Africa is weakly represented. Finland dominates...

Between Two Poles: Matching Trade and Exchange Rate Regimes in Mercosur AgEcon
Busse, Matthias; Hefeker, Carsten; Koopmann, Georg.
The paper reviews exchange rate options for Mercosur countries. We start from the observation that most of the countries in the region have a longstanding tendency to adopt fixed exchange rates, and ask how such a system could best be designed. The Argentine crisis has demonstrated that unilateral currency pegs imply the risk of serious misalignments with other trading partners and subsequent realignments. The standard basket peg is not a solution because of its limited transparency and credibility. We therefore discuss a proposal to create dual currency boards that could be a workable solution for the Mercosur countries.

Biofuels Potential in Latin America and the Caribbean: Quantitative Considerations and Policy Implications for the Agricultural Sector AgEcon
Ludena, Carlos E.; Razo, Carlos; Saucedo, Alberto.
Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops. Other countries in Latin America and the Caribbean have also expressed interest in biofuel production, and have started programs, and in some cases the legislation that promotes biofuel production. However, most of the analysis of biofuel crops has been...

Cattle Accumulation and Land Use Intensification by Households in the Brazilian Amazon AgEcon
Caviglia-Harris, Jill L..
In developing countries across the globe the impact of livestock on deforestation levels has been profound. This paper explores the role of the cattle industry in household decision making for small landholders in the Brazilian Amazon. Important inquiries raised in the literature are addressed, including the determinants of the co-evolution of deforestation and cattle herds, the possibility of production specialization, and the role of cattle in household livelihoods. Panel data suggest that households have changed focus from crop introduction to cattle. Empirical models reveal that location, wealth, and education are among the important determinants of production decisions and cattle accumulation. Policy recommendations include a focus on the cattle...
