The biodiversity loss is a worldwide major problem, it goes further from species and habitats loss, it also concerns human populations because there is a decline in the provisioning of ecosystem services that limits the satisfiers. The above makes it necessary that utilization and conservation plans must be designed from different scientific disciplines with an agroecological focus. The aim was to analyze Milpas from the Mazahua people, starting with a description of their performers and their contexts: cultural, environmental, and biological, related to food production. We analyzed Guarda de la Lagunita, a Mazahua community from the core of Mexico. Those Milpas are inside of a sensitive environment to biologic and social erosion. However, they are agroecosystems with polycultures that lodge place a striking plant and animal biodiversity and, they represent an important place to cultural, economic and social values. This feature makes those agroecosystems ideal places for the establishment of agroecological strategies that promote biodiversity, agriculture production, and social welfare. [ABSTRACT FROM AUTHOR]

The insects have been an important element not merely by their role in the terrestrial ecosystems, but likewise by their influence on human societies. Since the origins of human kind these organisms have been part of food, health, culture and agroecosystems where they have been not only competitors but also forecasters and carriers of ecosystem services. Due to great interest in the ecological restauration and models of sustainable development, such as the Agroecology, the insects are positioned as an excellent starting point for making development proposals that are consistent with the necessities of the modern society. The virtues that make insects an important knowledge system are discussed here. This scheme goes from natural and productive themes until social and cultural aspects that necessarily required transdisciplinary approaches in order to address this complexity, and they must be an important part for rural development from agroecology prespective.

Ants have been considered useful for bioindication because of their ecological characteristics. Nonetheless, among the characteristics of a bioindicator group, there must be a consistent and replicable response to disturbance. In this sense, divergent reactions have been found, even between taxons narrowly related. The objective of this work was to compare the diversity of the ant communities in three different temperate forests with different levels of disturbance, and to correlate their abundance and diversity of species, with that found in other arthropod communities of the same forests. The work was carried out in three municipalities in the North of the State of Mexico, where three types of different forests were identified by their degree of disturbance. These types include: 1) primary forest (PF), with typical species of a conserved forest; 2) mixed forest (MF), with species of a conserved forest and a reforestation effort; and 3) reforested forest (RF), with species used in reforestation efforts and indicative of disturbance. In each sample, an area of 2 500 m2 was selected. Each area had 16 pitfalls apiece and they were placed 10 m away from each other. Samples were collected twice; one from February through March 2009 (dry season) and another from August through September 2010 (rainy season), which produced a total of 192 traps. Obtained specimens were identified at the most taxonomically specific level. All data captured was transformed to vn + 0.5 and diversity index levels of Shannon and Simpson were calculated, as well as richness of species for ants, beetles, grasshoppers, true bugs, and spiders. The values of richness, diversity, and abundance were correlated with the Pearson coefficient, and to evaluate possible causal relationships between these, a path analysis was performed. Results suggested an important influence of the site over ant communities, and values of richness, abundance and diversity were correlated with the communities of spiders, beetles, grasshoppers and true bugs, but not for all the sites studied. Responses to environmental changes are not only on the numeric proportions of abundance, richness and diversity, but also in the indirect and casual ecological interactions. Finally, the data seems to indicate that the responses of the ants to the environmental changes are not necessarily reflected on other organisms' communities, so the ants' role as bioindicators can be limited.

Changes in diversity, species richness, abundance and similarity patterns of ants' communities in different managed areas in Central Mexico were studied. Three areas located in the Northwest of the State of Mexico were selected: native trees area with Quercus spp. forest (AN), combination area with Quercus spp. forest and Cupressus lindleyi as reforestation species (ZC), and reforested area (R), an altered forest with C. lindleyi. A total of 288 pit-fall traps were placed from February to March 2009 in sets of four traps in random quadrants of 10 m2. The community composition and abundance shifted according to the site conditions. The values of richness and species diversity were higher in R in comparison with AN and ZC. The results suggest a relative effect of changes in floristic composition on ants' community. Species as Temnothorax sp. 1 and Crematogaster sp., were abundant in preserved forest areas. In contrast, Pheidole sp. 1, Liometopum apiculatum and Camponotus atriceps were relatively common in disturbed habitats. [ABSTRACT FROM AUTHOR]

The Peruvian government enacted a new law granting consultation rights to indigenous peoples as a mechanism to enhance social inclusion in the country. The law generated debates about the criteria to identify indigenous population in the Andean region. Why does this law have problems granting consultation rights to Andean people? This paper aims to answer the question by reviewing historically the different Andean identities and analyzing the current international debate on indigenity. Our main argument is that the government in trying to apply the law is structuring a restrictive model that is hardly able to grasp the complexity and dynamism of Andean identities.

This essay examines the positions of Xavier Abril, Emilio Adolfo Westphalen, and José María Arguedas in the context of the discussions of the avant-garde, indigenismo and socialism that sought the renewal of the Peruvian imaginary between 1925 and 1940. The framework of the analysis intends to capture the complexity of the influences of José Carlos Marátegui's discourse in the debate, abandoning the contrast of the "Andean" and "West" categories and proposing a reading that emphasizes three other premises: authenticity, territoriality and modernity. In this sense, this work examines the relationship between Abril and Westphalen (1930-34), showing their image of Lima as a primitive space and a cultural wasteland in contrast to Europe and studying, among other texts, an unpublished manifesto. This paper then addresses the intellectual relationship between Westphalen and Arguedas at the end of the 1930s, showing how their representation of Lima as a hostile place was complemented by the proposal of an indigenous subject capable of the artistic modernity. This mapping of Lima's cultural scene of the time will explain how, according to these intellectuals, being primitive or modern depended on the authenticity of the artistic/intellectual pursuit.

Maize is attacked by various pests, and little research has been carried out on the diversity, ecological participation, and develop management strategies for weevils. Curculionids were obtained from a field at Irapuato, Guanajuato. Mostabundant species were Linogeraeus capillatus (72%), Geraeus senilis 19.5%), Nicentrites testaceipes (7.3%), and Linogereus hospes with 0.5%. The first was found from the V8 stage of development on, while the second and third were collected from V5 to R1. Photographs of genitalia and keys to species are included. [ABSTRACT FROM AUTHOR]

To identify entomopathogenic fungi present in the stable fly Stomoxys calcintrans, DNA of the mycelium recovered in mycosed specimens was purified. An amplification and sequencing of the ribosomal DNA region identified four species of parasitic fungi: Aspergillus tubingensis, Fusarium subglutinans, Beauveria bassiana, and Penicillium glabrum.

Hypertensive retinopathy is related to the time of exposure of the arteries to increased blood pressure, and its pattern is useful to estimate hypertensive disease evolution. The retinal arterial changes start with an initial acute vasoconstrictor phase, followed by a chronic sclerotic stage. Clinical studies have demonstrated a relationship between hypertension and left ventricle diastolic dysfunction. On the other hand, urinary albumin excretion is linked to subclinical organs damage, such as left ventricle hypertrophy and thickening of carotid artery wall; microalbuminuria is considered as a marker of morbidity and mortality in hypertensive patients. This study included 45 male hypertensive patients (blood pressure > 140/90 mm Hg, systolic/diastolic), age range 18-65 years old. Eye funduscopy and retinography was found normal in 19 (42.2%) patients hypertensive retinopathy was found in 2 (57.8%) of patients. Stage I retinopathy was found in 1 (35.5%)patients; Stage II in 9 (20.0 %) patients and Stage III in 1 (2.2%) patient. No patients showed Stage IV retinopathy. Left ventricle (LV) mass was found normal in 25 (55.6%) patients and left ventricle hypertrophy in 20 (44.4 %) of them. LV diastolic dysfunction (DD) was found in 21 (46.6%) patients; Type I DD was observed in 20 (44.4%) patients and Type II DD in only one (2.2%) case. No patients showed Type III DD. Microalbuminuria was found in 12 (26.7%) patients. When hypertensive retinopathy was matched to microalbuminuria, 19 (73.07 %) of patients did not have microalbuminuria and only 7 (26.9%) patients presented this disorder (Cramer coefficient of association= 0.007, p= 0.96). In conclusion, our findings do not demonstrate association between hypertensive retinopathy and microalbuminuria, as it has been shown in other clinical studies. [ABSTRACT FROM AUTHOR]
