“…Además, este estudio sugiere que el Bioparque Puquén está cumpliendo una función fundamental como área de amortiguación de la franja costera colindante, la cual es parte del sitio prioritario para la conservación de la biodiversidad (CONAMA, 2007). Recientemente se anunció la creación del Santuario de la Naturaleza Cerro San Inés (Napolitano et al, 2020). Sin embargo, los resultados de este estudio sugieren que la franja costera colindante al parque debería ser protegida a la brevedad, dado que alberga una mayor abundancia de especies de micromamíferos que el área protegida y especies endémicas como O. degus y A. longipilis que no se detectaron en el parque.…”

“…Esto da cuenta de la importancia de conservar áreas de gran tamaño que alberguen distintos tipos de biotopos. Urge proteger la mayor parte posible de la franja costera estudiada en este trabajo para asegurar la conexión de las poblaciones que habitan en cada biotopo mediante la utilización de corredores biológicos como el caso de la Quebrada Manantiales para conectar el cerro Santa Inés con áreas de la franja costera como se reportó para la güiña Leopardus guigna (Napolitano et al, 2020). En nuestro trabajo se estudió la Quebrada Agua Salada que podría cumplir un rol similar.…”

The conservation of biodiversity in Mediterranean Chile requires a greater coverage than that represented in the Protected Wild Areas of the State (SNASPE) and Private Protected Areas (APP) are complementary alternative for conservation. The study of biodiversity in APP is scarce, ignoring its contribution to the conservation. The small mammals assemblage of the APP Bioparque Puquén and surroundings was described comparing the species richness, relative abundance and diversity index of Margalef inside and outside the park. Using the Morisita-Horn similarity index and a cluster analysis, the small mammals assemblage was compared between sampling points categorized in different biotopes. Endemic and native species were more abundant outside the APP. There were no significant differences in specific richness or diversity inside and outside the APP. The small mammals assemblage was grouped into biotopes of dense native vegetation and prairies, ravines and seasonal waters. The park would act as buffer area, protecting the nearby areas of the Los Molles-Pichidangui Priority Site. The importance of rocky outcrops as a habitat for endemic species of small mammals and protecting the areas adjacent to the BioParque is discussed.

“…It is endemic to central and southern Chile and a thin strip of Western Argentina. In detail, northernmost observations of this species have been made in the Chilean Coquimbo Region, at about 31 • South, while the southern limit of its known distribution range is in the Aysén Region of Chile, at 48 • South [1]. This area has long since been characterized by vast native forests that provided ample space to these territorial cats.…”

“…• • • Males were therefore more likely to come into contact with humans, their pets, and domestic fowl." (1) The fact that females rarely explore beyond a rather small home range within their habitat could be interpreted as an evolutionary response to the presence of predators and other types of threats. In modern times, it may also help to avoid hazardous contact to men and domestic animals.…”

Scarcity of information regarding the natural history of Leopardus guigna, an endangered felid native to Chile and western Argentina, hampers the successful implementation of conservation strategies. Very little is known about the movement behavior of L. guigna and home range estimates rest on less than a handful of radiotracking studies. Due to the difficulties inherent in any study requiring the live capture of protected species, we suggest a mathematical approach to the modeling of territories occupied by individual guignas. Our approach is based on the hypothesis that L. guigna maintains a sedentary behavior in a specific area of a given territory, whereby starting points can be derived from point observations. In this context, the present article shows a way to simulate a distribution of points in a territory using random walkers to emulate field data as could be obtained by means of telemetry. Our model allows for an estimation of mean distances covered by individual cats from a fixed starting point and thus enables the prediction of interactions with known threats to the species, such as motor vehicles, free-roaming dogs, and people. The knowledge gained in this process can be of much help when defining the boundaries of protected areas and, more generally, in the planning of infrastructure, rural and urban development.

Considering that there is very little information on the behavior habits of guigna cats, as well as investigations in which small populations are captured to place radiocollars on them and then release them in the place where they were captured, which is done with the intention of collecting data on their positions in a territory and thus make estimates of the mean distances they usually travel. Under the hypothesis that guignas maintain a sedentary behavior in a specific area of a given territory, this paper shows one way to simulate a distribution of points in a territory using random walkers to emulate the distribution of the data that would be obtained by placing radiocollars in a population of guignas, with which it is possible to make estimates of the mean distances that move away from a certain fixed position, and the interactions they can have with points in the territory that represent a high probability of lethality, such as farms, packs of dogs, roads, urban areas, etc. It is necessary to mention that by estimating the possible interactions that a guignas population may have with possible predators in a territory with the help of a satellite image, it is possible to evaluate the points of a territory that represent a potentially lethal risk for the guignas, and thus generate relocation strategies that help preserve them.
