This paper describes the life of the mine master Juan de Buendía who went to Peru in 1609 to implement the mining techniques of the Almadén mine in the mercury mining of Huancavelica. The contributions that he made are also discussed, especially in timber framing, which made it possible to improve the safety and exploitation of the mine to levels never seen before..

Chinchillula sahamae Thomas, 1898 is a sigmodontine rat, known to occur in southern Peru, northern Chile, and western Bolivia. In this study, we report new records of the species in the departments of Huancavelica and Junín, Peru, which extend this species’ known distribution 370 km northwest, and new records in the department of Tacna, which extend the upper elevational range of the species to 5100 m, 250 m higher than previously known. In addition, we include notes on natural history, especially nesting behaviour, based on direct observations. [ABSTRACT FROM AUTHOR]

This work deals with the biography of Juan de Sotomayor, an important miner who exploited some mercury mines in Huancavelica (Peru) between c.1572 and 1610. For this, in addition to documents of the time, his will, recently discovered in the Archivo Histórico Provincial of said city, is presented here for the first time. This work notably broadens the knowledge about Sotomayor, who has received little attention from researchers despite his historical importance since he was one of the main suppliers, if not the first, of the quicksilver that was used in Potosí for the amalgamation of the silver that, sent to Europe, financed the maintenance of the Spanish empire.

The José María Arguedas' grass mouse, Akodon josemariarguedasi, is currently known from the central Yungas of Peru, ranging from the right (south) side of the Río Huallaga in Huánuco Department (in the north) to Junín Department (in the south); its phylogenetic affinities are unknown. We collected four specimens from Quintao, Tayacaja, Huancavelica Department allocated to this species, extending the species range 144 km farther south from its previous known distribution; and inferred the phylogenetic relationships of this species within the aerosus species group based on molecular analyses of the mitochondrial cytochrome b gene. We confirm that A. josemariarguedasi is a member of the aerosus species group and it is a sister taxon to Akodon mollis "Ancash" and then to Akodon torques. Also, we found that Akodon kotosh is closely related to Akodon orophilus, and not A. josemariarguedasi. Finally, we confirm that Akodon budini and Akodon siberiae are also members of the aerosus species group. [ABSTRACT FROM AUTHOR]

The biological monitoring of Cerro del Águila Hydroelectric Plant was developed as part of the commitments assumed in the Environmental Impact Assessment (EIA), which was approved through the Directorial Resolution No. 049-2013-MEM/AAE in August of 2013. The study area is located in Colcabamba and Surcubamba districts, Tayacaja province, Huancavelica department, corresponding to the Mantaro River Valley. Fieldwork was carried out between 2013 and 2016, during the wet and dry seasons of each year. As a result of this study, three species report extensions in their ranges of distribution: the White-Ear Buco (Nystalus chacuru), the Pearl Belly-Tyrant-Todi (Hemitriccus margaritaceiventer) and the Red-crested Finch (Coryphospingus cucullatus). These are species whose records in this area show variations in frequency and abundance between seasons and type of vegetation, possible related to the construction phase of the project.

A checklist of grasses (Poaceae) from Huancavelica is presented consisting of seven subfamilies, 21 tribes, 74 genera, 255 species, two sub species, eight varieties, two forms and a hybrid. The checklist consolidates the agrostologic flora from the Huancavelica region. Sources range from years of field collections to consultations from Peruvian herbaria. Records are supported by vouchers, of which, the majority are accessible via searchable databases and published references. [ABSTRACT FROM AUTHOR]

We describe a new species of Telmatobius from the Pacific slopes of the Andes in central Peru. Specimens were collected at 3900 m elevation near Huaytará, Huancavelica, in the upper drainage of the Pisco river. The new species has a snout–vent length of 52.5 ± 1.1 mm (49.3–55.7 mm, n = 6) in adult females, and 48.5 mm in the single adult male. The new species has bright yellow and orange coloration ventrally and is readily distinguished from all other central Peruvian Andean species of Telmatobius but T. intermedius by having vomerine teeth but lacking premaxillary and maxillary teeth, and by its slender body shape and long legs. The new species differs from T. intermedius by its larger size, flatter head, and the absence of cutaneous keratinized spicules (present even in immature females of T. intermedius), and in males by the presence of minute, densely packed nuptial spines on dorsal and medial surfaces of thumbs (large, sparsely packed nuptial spines in T. intermedius). The hyper-arid coastal valleys of Peru generally support low species richness, particularly for groups such as aquatic breeding amphibians. The discovery of a new species in this environment, and along a major highway crossing the Andes, shows that much remains to be done to document amphibian diversity in Peru. [ABSTRACT FROM AUTHOR]

The article provides an analysis of three historical forms of political subjectivity in South-Central Peru: the montoneros, the gamonales and the post-conflict politicos. Based upon a historical sociology of puna–valley relations, the article suggests that subjectivities should be read not as emanating from either side of the racialised misti– Indio divide, but instead as fractals of this.

INTRODUCCIÓN: La anemia y la desnutrición infantil es una de las causas de la salud pública mundial problemas. En Perú, la desnutrición infantil y la anemia afectan al 13,1% y al 3,6% de los niños menores de 5 años años de edad, respectivamente, siendo la región de Huancavelica la que registra el mayor número de casos. Entre los programas sociales enfocados en mejorar la nutrición y el desarrollo cognitivo son: Juntos, Cuna Más y Qali Warma. Sin embargo, no hay cambios sustanciales en estado nutricional y cognitivo. OBJETIVO: Determinar los factores asociados con asistencia a programas sociales y la prevalencia de anemia y desnutrición en niños de 1 a 5 años en Huancavelica. MATERIALES Y MÉTODOS: Estudio observacional analítico, tipo cohorte longitudinal retrospectivo. La población será de 1000 niños, entre 1 y 5 años de las comunidades de Viñas, y Acobambilla - Huancavelica. La información sobre el estado nutricional del programa será solicitado a la Dirección Regional de Salud de Huancavelica. Se realizará una encuesta para la madre sobre la recepción de programas sociales con consentimiento informado. Los resultados serán analizados utilizando Stata 16, medidas de tendencia central, análisis bivariado y el Chi-cuadrado y T métodos estadísticos de estudiantes. RESULTADOS: La eficacia de la asistencia a los programas sociales para la anemia y los factores contribuyendo a la disminución de la desnutrición en niños de 1 a 5 años en Viñas y Acobambilla-Huancavelica.
