Abstract In this work I am interested in marking how the academic and management matrices intersect, when it comes to coordinating the design and implementation of a government policy for the integral urbanization of the habitat. From a work experience that committed me as a manager from the academic field, I seek to describe with the greatest possible density, the incidence of categories of the scientific field in the production and implementation of projects promoted from the program. These new dimensions meant the emergence of tensions in the traditional approaches to the social issue in the Neighborhood Improvement Program (PRO.ME.BA), both at the level of the workers of the program, and of the citizens themselves (before “target population”), in a province in northeastern Argentina. intersect habitat density program PRO.ME.BA, PROMEBA PRO.ME.BA , PRO ME BA (PRO.ME.BA) before target population, population population”) Argentina (PRO.ME.BA population”

Abstract An outbreak of avian botulism type C occurred at the Kelp Gull (Larus dominicanus) colonies located at the Nahuel Huapi National Park and lake area in Argentina, at the end of the breeding season, during austral summer 2020. While conducting fieldwork, birds were observed with paralysis of the lower and upper limbs, and dead birds were found in a sitting down position with no signs of having been attacked. We collected blood and tissue samples from eight Kelp Gulls and one Ashy-headed Goose (Chloephagapoliocephala) for toxicological analysis. One sample of Ashy-headed Goose resulted positive for botulinum toxin type C. Diseases like botulism are usually lethal for wildlife and have important effects on bird populations. Though the impact on the Kelp Gull colonies did not seem to be of great concern (~2.3% of the population affected), specific research into the source of the toxin and the initiating conditions are required to understand the potential threats to the environ- ment and to different bird populations that live in this area. This would be key for aquatic bird species such as the Ashy-headed and the Upland Goose (C. picta), both considered threatened in Argentina.

Nothofagus nitida is an evergreen tree species considered endemic to the humid forests of Southern Chile. In this study, we inform the finding of N. nitida individuals on the eastern slopes of the Andes in Argentina, expanding its potential geographic distribution range, restricted until now to humid areas west of the Andean range, in Chile. New localities correspond to the south outlet of Menéndez Lake on riverbanks of Río Alerce and Río del Paso Viejo, in Los Alerces National Park, Chubut Province, Argentina. Samples of fresh leaves were collected from five individuals that were considered as putative N. nitida, based on leaf and bark morphology. We performed automated sequencing of the ITS nuclear DNA region, which was previously used to identify different species of subgenus Nothofagus. Four of the obtained DNA sequences corresponded to N. nitida. In addition, we carried out a species distribution model that showed other potential areas of occurrence in Argentina. This finding merits the exploring efforts in other localities at the East of the Andean Range, using as guidance the potential distribution maps in order to determine its current distribution and genetic markers to confirm its presence.

Nothofagus nitida es una especie arbórea siempreverde considerada endémica de los bosques húmedos del sur de Chile. En este estudio, se informa el hallazgo de individuos de N. nitida al este de Los Andes en Argentina, ampliándose su área de distribución geográfica potencial, hasta ahora documentada solo para zonas húmedas al oeste de la Cordillera de Los Andes, en Chile. Las nuevas localidades corresponden al Brazo Sur del Lago Menéndez a orillas de los ríos Alerce y del Paso Viejo, en el Parque Nacional Los Alerces, Provincia de Chubut, Argentina. Se tomaron muestras de follaje fresco de cinco individuos que fueron considerados N. nitida putativos a base de la morfología foliar y corteza. Se extrajo ADN, se amplificó mediante PCR y se secuenció de manera automática la región ITS del ADN nuclear que permite identificar las distintas especies del subgénero Nothofagus. Las secuencias de ADN obtenidas de cuatro individuos correspondieron de manera inequívoca a N. nitida. Por otro lado, se realizó un modelado de la distribución de la especie que mostró otras áreas potenciales de ocurrencia en Argentina. Este hallazgo amerita la realización de esfuerzos para su búsqueda en otras localidades al este de Los Andes, utilizando como herramienta los mapas de distribución potencial a fin de determinar su distribución y utilizar marcadores genéticos para confirmar su presencia.

This article analyzes the characteristics of a negotiation process between political and technical gropus during the implantation of a reform process of the Human Resources Management (HRM) system in a public organization. It also investigates the impact of that implementation on intermediate hierarchies. This reform process, developed on a municipality of Corrientes (Argentina) was constituted as the first systematized effort for reorganizing the HRM system. The discussions are articulated around the role of the political civil servants, that of the civil servants of the intermediate hierarchies and, as a mediating figure, the technical personnel in HR. The methodology, preponderantly qualitative, seeks to analyse the administrative and institutional processes from the perspective of its actors. Information was gathered that allowed describing the weight of the political decision in this type of proposition, the contribution of the hierarchic intermediate line and that of the professional / technical support teams is of balance between the political requests and the needs of the service.

Este artículo analiza las características de un proceso de negociación entre cuadros políticos y técnicos respecto de la implantación de un proceso de reforma del sistema de Gestión de Recursos Humanos (GRH) en un organismo público, como también el impacto que a nivel de jerarquías intermedias obtuvo tal propuesta. La misma, desarrollada sobre un municipio de Corrientes, se constituyó en el primer esfuerzo sistematizado en tal sentido. Sobre los roles de los componentes de este proceso (políticos, funcionarios de carrera y técnicos en Relaciones Laborales) se articulan las discusiones en torno a la implantación de tal reforma. Con un enfoque metodológico preponderantemente cualitativo se buscó dar cuenta de los procesos administrativos e institucionales desde la perspectiva de sus actores. La información recogida permitió describir el peso de la decisión política en las propuestas de cambio, el aporte de la jerarquía intermedia, y el rol de los equipos técnicos en el balance de las necesidades políticas y del servicio.

We describe the first documented nest of the Chilean Hawk (Accipiter chilensis) in Argentina, and give details on the nesting behaviour of parents and nestlings during the fledging stage of the nesting cycle. The nest was found in a coihue (Nothofagus dombeyi) forest in the Nahuel Huapi National Park, Río Negro Province, Argentina. The nest structure was a platform of sticks built 25.3 m in the canopy of a coihue tree. On three visits to the nest between January and February 2004, we observed adults bringing avian prey items to the nestlings in the nest.

Documentamos por primera vez la nidificación del Peuquito (Accipiter chilensis) en Argentina y proporcionamos detalles sobre el comportamiento parental y de los pichones. El nido fue encontrado en un bosque de coihue (Nothofagus dombeyi) en el Parque Nacional Nahuel Huapi, provincia de Río Negro, Argentina. Consistía en una plataforma de ramas construida a 25.3 m en la copa de un coihue. En tres visitas al nido entre enero y febrero de 2004 observamos adultos llevando presas (principalmente aves) a los pichones en el nido.

The morphological and behavioral development of white-throated hawk (Buteo albigula) nestlings was studied near San Carlos de Bariloche, in northwestern Argentine Patagonia. The study was mainly based on the monitoring of two nestlings produced at different nests during 2001-2002 breeding season, and was reinforced with data obtained at libitum in other nests the same and previous breeding seasons. The nestling period extended for approximately 6 weeks. Morphological development was characterized by several changing features, but the most surprising was the development of first and second natal down, which was only known, among Neotropical Buteo species, for B. brachyurus. Nestling behavioral development matched the general patterns observed for Buteo spp. of comparable body size. Besides, a juvenile (dead accidentally) was characterized for the first time in Argentina, and two adults, banded near their nests, were measured and weighed (first data for B. albigula). The juvenile was relatively similar to that described in Chile. The adults, which would be the first white-throated hawks ever banded, add to the few specimens measured in the breeding range known for the species.

El desarrollo morfológico y conductual del aguilucho chico (Buteo albigula) en el nido fue estudiado en cercanías de San Carlos de Bariloche, al noroeste de la Patagonia argentina. El estudio se basó en el seguimiento de dos pollos producidos en diferentes nidos en la temporada reproductiva 2001-2002, y se lo complementó con datos tomados ad libitum en otros nidos, esa misma y anteriores temporadas. Los pollos permanecieron en el nido por aproximadamente seis semanas. Durante su desarrollo morfológico se evidenciaron diversos cambios; notablemente, la aparición secuencial de dos plumones natales, que solo fue observada entre especies de Buteo neotropicales, para B. brachyurus. La conducta de los pollos se encuadró en los patrones comunes para otras especies de Buteo de tamaño corporal similar. Además, se caracterizó, por primera vez para la Argentina, un juvenil (muerto accidentalmente), y se tomaron medidas y peso (por primera vez para B. albigula) de dos adultos anillados cerca de sus nidos. El juvenil fue relativamente similar al descrito en Chile. Los adultos, que serían los primeros aguiluchos chicos en ser anillados, se suman a los escasos ejemplares medidos en el área reproductiva conocida de la especie.
