The fight against imperialism and racism was central to the Comintern's political and cultural program of the interwar period. Although the more immediate interests of the Soviet state would come to overshadow such causes, the cultural and political connections forged during this time influenced later forms of organizing. Throughout the interwar period (1918-39), the Soviet Union served as the core location of a newly formed world-system of socialist and communist radicalism. The origin of Latin American Marxism in the work of the Peruvian theorist and political organizer José Carlos Mariátegui, as well as the politically committed literature associated with the interwar communist left in the Andean region of Latin America, shows how literature and theory devoted to the indigenous revolutionary contributed to interwar Marxist debates. The interwar influence of Mariátegui and César Vallejo makes clear the importance of resisting attempts to drive a wedge between the two authors and the broader communist movement at the time.

Abstract G. rostochiensis is a world wide pest of temperate areas, including both temperate countries and temperate regions of tropical countries, for example India's Nigrilis region. Distribution is linked to that of the potato crop. Potato cyst nematode is considered to have originated from the Andes region of South America, from where it spread to Europe with potatoes. The ease with which it has been transported across continents proves what a resilient pest it is. The cyst form which adheres to host roots, stolons and tubers and to soil particles during transportation gives rise to new infestations where climate and food source are both available and favourable. Secondary means of dispersal is through the movement of contaminated farm machinery, farming implements and contaminated footwear. Cysts are also successfully spread by wind dispersal, during winter storms or sand storms where top soil is redistributed. Rain which causes flooding and water to run off fields into trenches or irrigation channels also redistributes cysts into adjoining areas.

Cavendishia bracteata and Thibaudia floribunda (Ericaceae) are wild fruit shrubs native to the Andes region. This study aimed to characterize the rooting potential of basal and apical cuttings using naphthalene acetic acid (NAA) in different concentrations (0, 200, 500, or 1,000 mg L-1). In C. bracteata, the cutting position on the branch affected its sprouting and rooting, with apical cuttings presenting the best performance with auxin application. The rooting of cuttings was more successful in C. bracteata than in T. floribunda. NAA applications between 200 to 500 mg L-1 were more suitable for the propagation of C. bracteata due to the higher percentages of rooting and shoot production. For propagation of T. floribunda, the use of apical cuttings without the application of auxins is recommended. Adventitious roots in cuttings of both species were originated from parenchyma cells of the stem.

Potato is an important crop for Venezuelan agriculture. However, its production is highly affected by late blight (Phytophtora infestans), since weather is commonly favorable for this disease. The aim of this study was to determine the sowing dates of low climatic risk for potato late blight in the Andes region of Venezuela, with an agrometeorological disease model and geographical information system (GIS) tools. The disease model used in this study was developed by Hyre (1954) which requires daily rainfall and temperature data which were obtained from 106 weather stations, located at the States of Mérida, Táchira, and Trujillo, for a period of 31 years. Hyre's model was applied for all stations obtainig the following variables: number of disease favorable days (DFD); number of periods with ten consecutive favorable days, named disease occurrence (O); and number of sprays required for disease control (S). These variables were used to calculate the Maximum Risk Index (MRI) and the Probable Risk Index (PRI). The interpolation of these indexes was used to generate maps of climatic risk for each sowing date. MRI and PRI maps showed that the highest climatic risk for potato late blight occurrence was during the rainy season, from May to July, decreasing during dry and mid seasons. However, high disease risk variability was observed for all seasons. The maps generated by coupling an agrometeorological disease model and GIS also show that in great part of potato areas of Andes region the number of sprays could be reduced, but more investigations about that must be carried out.

Colombia is the country with the highest number of orchid species (4270), whose optimal habitat is cold and humid forests. However, the outlook for conservation is alarming, considering that deforestation is causing the loss of millions of hectares of forests. This situation has led to the existence of 206 endangered orchid species. Therefore, this research was conducted to determine Sites of Special Importance for the Conservation of Threatened Orchid Species in Colombia (SSICO), through an analysis of their spatial and altitudinal distribution using various databases, to make a selection of nature reserves on a municipality scale, using Marxan software, and employing relevant parameters (richness, rarity, and IUCN category). Furthermore, the results were later compared with the Protected Areas System, determining their coverage to propose SSICOs. 674 records of the presence of threatened orchids in 277 municipalities were obtained. Urrao, Abrego, and Frontino were the areas with the greatest richness and rarity. Marxan selected 47 municipalities located mostly in the Andes region, and four SSICOs were prioritized, which are located in the Antioquia, Norte de Santander, Nariño and Putumayo provinces. These SSICOs, in addition to being points of great biodiversity, are areas with special socio-economic characteristics that influence the management of natural resources. These areas require timely attention, research, and intervention by environmental authorities because of their importance for conserving orchids and Andes Forests.

Ozone Variations

Abstract. Since November 1993 up to present from Benegas Station, Mendoza, Argentina (site of IEMA Institute) and from high locations in the Andes region, ground based radiometric measurements of stratospheric ozone and tropospheric water vapor have been achieved. Ozone measurements are performed by using a radiometer-spectrometer tuned at 142 GHz and tropospheric water vapor by means of a 92 GHz radiometer. In this paper two case studies of large stratospheric ozone variations due to dynamical processes will be presented. These processes are very likely associated to gravity waves, generated by airflow over the Andes Mountains, or due to Zonda wind effect.
