ABSTRACT

Lama guanicoe se distribuyó en los Andes de Chile desde Arica y Parinacota hasta Magallanes. Actualmente su distribución está fragmentada con poblaciones en las regiones de Tarapacá, Coquimbo, Aysén y Magallanes. En el Parque Nacional Bosque Fray Jorge (Coquimbo), las últimas poblaciones de guanacos silvestres se observaron el año 1920. En 1994 se liberaron ocho individuos en el Parque de los cuales cinco sobrevivieron. Desde entonces se realizaron conteos ocasionales de la población reintroducida. En noviembre de 2013 se elaboró una metodología de monitoreo con base en transectos de conteo. Los objetivos fueron analizar los cambios históricos de la abundancia poblacional de guanacos en el Parque y determinar el uso y selección de hábitat. Se emplearon modelos lineales para analizar las tendencias poblacionales y el Cociente de Selección de Manly para la selección de hábitat. Se evidenció incremento de la población hasta 33 individuos. El principal uso que dieron a los tipos de cobertura fue la alimentación y seleccionaron el Matorral Desértico Mediterráneo Interior de Heliotropium stenophyllum y Fluorensia thurifera. Se recomienda marcar los guanacos con collares satelitales para hacer un seguimiento de los movimientos de las tropas, establecer territorios y medir el tamaño poblacional.


Lama guanicoe was distributed in the Andes of Chile from Arica and Parinacota to Magallanes. Currently its distribution is fragmented with populations in Tarapaca, Coquimbo, Aysen and Magallanes Regions. In the Bosque Fray Jorge National Park (Coquimbo), the last populations of wild guanacos were observed in the year 1920. In 1994, eight individuals were released in the Park, of which five survived. Since then, occasional counts of the reintroduced population were made. In November 2013, a monitoring methodology was developed based on count transects. The objectives were to analyze the historical changes in the population of guanacos in the Park and determine the use and selection of habitats. Linear models were used to analyze population trends and the Manly Selection Ratio for habitat selection. There was an increase in the population to 33 individuals. The main use that they gave to the types of cover was the feeding and they selected the Mediterranean Mediterranean Desert Scrub of Heliotropium stenophyllum and Fluorensia thurifera. It is recommended to mark the guanacos with satellite collars to monitor the movements of the troops, establish territories and measure the population size.

ABSTRACT

Um exemplar macho, subadulto de onça parda reintroduzido foi monitorado por técnica de radiotelemetria. O monitoramento foi de 110 dias, realizado de forma aleatória, com intervalos descontínuos. Os dados do acompanhamento sugerem que a área utilizada por este espécime seja de, aproximadamente, 26km². Esta configura o menor índice já descrito para a espécie, porém, deve-se ressaltar a importância deste monitoramento básico, visto a incipiência do comportamento de um felino de grande porte reintroduzido em habitat natural após período em cativeiro.


One subadult male specimen of a reintroduced mountain lion was monitored using the radio telemetry technique. The monitoring lasted 110 days, being randomly distributed. Data of the monitoring through radiotelemetry suggested that the home range of this specimen was of approximately 26km². This sets as the smallest home range described for this species. However, the importance of this basic monitoring should be emphasized, since information of the behavior of a large feline reintroduced in its natural habitat after a period in captivity is incipient.
