“…Several of our captures were of 2 animals in the same group of traps. This behavioral trait was previously described for the same species in the Patagonia region by Redford and Eisenberg (), and is in agreement with other anecdotal observations from Argentina (Jayat et al , Tellaeche et al ) and the hypothesis that G. cuja tends to form monogamous pairs (Nowak ).…”

“…This information will support future research and conservation planning for a species that tends to be particularly susceptible to anthropogenic threats (Miller et al , Valenzuela‐Galván et al ). Lesser grison captures occurred mostly during daylight hours in accordance with the observations recently reported for the high Andes (Tellaeche et al ) and this suggests that lesser grisons would be largely diurnal. Several of our captures were of 2 animals in the same group of traps.…”

We assessed chemical immobilization and success of trapping devices on a little-known South American mustelid, the lesser grison (Galictis cuja). From December 1998 to June 2006, we live-trapped (n ¼ 23) and radiomarked (n ¼ 9) free-ranging lesser grisons in 2 areas of the Pampas grasslands of Argentina. Both box-traps and rubber-padded leg-hold traps allowed us to capture lesser grisons. However, leg-hold traps had greater capture efficiency. Although the liberation time was longer with tiletaminezolazepam than ketamine-xylazine, field immobilization of lesser grisons with both drug combinations was effective and safe. The high frequency of thermal regulation problems suggests that body temperatures of chemically restrained lesser grisons should be routinely monitored. Neither collars nor backpack harnesses were effective methods for attachment of radiotransmitters. Trapped individuals showed male-skewed sexual size dimorphism and sex ratio. Capture times suggest that lesser grisons are largely diurnal. Most of the data presented in this study are the first published on the lesser grison and provide baseline information for future research and conservation. Ó

“…Indeed, in many regions culpeos are considered mainly nocturnal. The same nocturnal activity patterns were also observed in other areas of Argentina (Walker et al 2007, Tellaeche et al 2014). While moon light did not seem to affect the activity of the culpeo (Lucherini et al 2009), peaks of activity have been recorded at different times of the night (Monteverde & Piudo 2011).…”

“…It also can occupy humanized habitats (Salvatori et al 1999) and areas dedicated to livestock (Johnson & Franklin 1994b,b, Pía 2013, where its abundance can be high, even similar to that of wellpreserved areas (Pia et al 2003). Culpeo populations can reach high altitudes, up to 4,800 masl (Jiménez et al 2008), such as the high steppes of the Andes and the puna's grasslands of Argentina (Pia et al 2003, Walker et al 2007, Tellaeche et al 2014, Palacios et al 2012, Cuyckens et al 2015 and Chile (Marquet et al 1993, Johnson & Franklin 1994a,b, Pacheco et al 2004.

A deep review of the existing literature on the culpeo ecology is carried out, using scientific articles, book chapters and web resources. For information published before 1988, the synthesis made by a previous report was used. For subsequent information, bibliographic searches were carried out through the main servers, considering all of the generic names used to define the species so far. From this update, new general patterns on ecology, behavior and conservation concerns about culpeos are described. Gaps in current knowledge have been identified and new lines of research are proposed.Most of the studies focused on diet, conflicts with the species in livestock areas, and on the use of space and habitat. We found an incomplete, poor justification for all of the proposed subspecies and their supposed geographical distribution, as well as a scarcity of studies on genetic issues, population dynamics and conservation concerns. It is remarkable that vast regions in South America holding culpeos lacked basic information on the species.Diet studies describe a marked trend towards resources selection at the local level, which supports the view of the culpeo as a facultative trophic specialist. In addition, it has been confirmed that in the high Andes the culpeo is also a top predator that may regulate carnivorous communities, as well as that in arid environments culpeos can act as important seed dispersers. The assessment of the conservation status of the species differs among regions, although there is no sufficient information to reach clear conclusions in most cases. Even so, in Ecuador and Colombia the species has been listed as ‘Vulnerable’. Direct persecution and habitat alteration are considered to be the most important threats that the species is facing in many countries, although other risk factors such as climate change could also have serious consequences for the canid at the global scale.

“…It is described along the entire Chilean territory as using diverse habitats [53], but it is scarce and hard to record in central Chile (mean home range of 14.9 km 2 [54]). C. chinga, with a crepuscular-nocturnal habit (mean home range of 1.8 km 2 [55]) and G. cuja, with a diurnal habit (no home range information available) are scarcely studied in Chile, but with a wide distribution in South America, they occupy a wide diversity of environments being generalists in terms of diet and habitat, but with a suggested niche segregation between them [56,57].…”

Natural habitats in South America have been intensively used and modified, including their conversion to exotic tree plantations, impacting the terrestrial fauna communities. Carnivores play an important role in the functioning of ecosystems as apex predators. Landscape characteristics and resource availability determine the composition and abundance of co-occurring carnivores. We hypothesized that the diversity and relative abundance of native carnivores varied in relation to the different vegetation macrohabitats. We predicted that native forests support a higher diversity and abundance of native carnivores compared to exotic plantations. Between 1 March 2021 and 31 March 2022, we estimated the species’ richness, composition, and relative abundance of terrestrial native carnivores in three different landscapes of the Coast Range in central Chile, as shown in the following: (a) the monoculture plantation of the exotic Pinus radiata (MP); (b) the Mediterranean coastal thorn forest (TF); and (c) the Mediterranean coastal sclerophyllous forest (SF). We monitored an area of 1000 ha in each landscape, installing 10 camera traps (total of 30 camera traps). We used a monitoring transect with unbaited camera traps separated by 1 km, with a total photo-trapping effort of 10,046 camera days. The classification, organization, and analysis of camera trap data were conducted using CameraSweet software. The total number of independent native carnivore species events (photos separated > 60 min) recorded in each landscape were 1564 in SF, 1412 in TF, and 775 in MP. Carnivore richness and composition were not significantly different in all three landscapes. We detected five native carnivore species. Relative abundance by species was significantly higher in SF compared to MP for Leopardus guigna, Conepatus chinga, and Galictis cuja and also significantly higher in TF compared to MP for L. guigna. Our results suggest that the native vegetation cover must be preserved to maintain viable and abundant native carnivore populations, crucially relevant in the highly impacted and human-dominated global biodiversity hotspot of Central Chile. This study contributes to informing evidence-based decision-making and conservation strategies at the landscape level to mitigate biodiversity loss.
