South American fox

The South American foxes, comprising the genus Lycalopex in the family Canidae, are six species of small to medium-sized canids endemic to mainland South America south of Panama, characterized by their versatile adaptations to diverse environments and omnivorous feeding habits.^[1] These "false foxes," more closely related to other South American canids, such as the maned wolf, than to true foxes of the genus Vulpes, feature variable pelage in shades of gray, rufous, or fawn, bushy tails often tipped in black or white, and a dental formula of 3/3, 1/1, 4/4, 2/3 = 42 teeth, enabling them to consume a broad diet including small mammals, birds, insects, fruits, and occasionally larger prey like rodents or ungulates.^[1]^[2] The genus encompasses the culpeo (L. culpaeus), the largest species at up to 13.5 kg and distributed across Andean and Patagonian regions from Colombia to Tierra del Fuego in countries including Ecuador, Peru, Bolivia, Chile, and Argentina; the South American gray fox or chilla (L. griseus), a widespread inhabitant of southern Argentina and Chile from arid plains to forested foothills; the pampas fox (L. gymnocercus), adapted to open grasslands and shrublands in Argentina, Bolivia, Paraguay, Uruguay, and southern Brazil; Darwin's fox (L. fulvipes), a small, forest-dependent species restricted to Chile's Chiloé Island and adjacent mainland Nahuelbuta ranges; the Sechuran fox (L. sechurae), confined to coastal deserts of southwestern Ecuador and northwestern Peru; and the hoary fox (L. vetulus), Brazil's smallest canid, primarily found in the Cerrado savanna biome.^[1] Ecologically, Lycalopex species are habitat generalists that thrive in modified landscapes, often exhibiting solitary or paired social structures with crepuscular or nocturnal activity patterns influenced by predation risk and resource availability, and they contribute to ecosystem balance as predators of pests and dispersers of seeds.^[1] While most are resilient due to high reproductive rates—typically producing 2–7 pups per litter after a 50–60-day gestation—the genus faces varying threats from habitat fragmentation, agricultural expansion, persecution as livestock predators, and diseases like rabies and canine distemper, leading to conservation statuses that range from Least Concern for the culpeo, chilla, and pampas fox to Endangered for Darwin's fox (with approximately 600 mature individuals) and Near Threatened for the Sechuran fox and hoary fox amid ongoing Cerrado deforestation (as of 2024).^[1]^[3]^[4]

Taxonomy

Etymology and names

The genus name Lycalopex derives from the Ancient Greek terms lykos (λύκος), meaning "wolf," and alopex (ἀλώπηξ), meaning "fox," highlighting the species' morphological and behavioral traits that blend features of both wolves and foxes. This nomenclature was first proposed by Hermann Burmeister in 1854 for certain South American canids, emphasizing their distinct evolutionary position within the Canidae family.^[5] Historically, South American foxes were classified under the genus Dusicyon, established by Oldfield Thomas in 1914, which translates from Greek as "almost a dog" (dusi- meaning "imperfect" or "almost" and kyon meaning "dog"), underscoring early perceptions of their dog-like qualities.^[6] However, taxonomic revisions in the late 20th century, driven by morphological analyses such as those by Zunino et al. in 1995 and subsequent studies like Slater et al. in 2009, reclassified the group into the unified genus Lycalopex (incorporating former Pseudalopex), confirming their monophyly and closer affinity to vulpine forms.^[7] Common names for South American foxes reflect a mix of colonial Spanish, Portuguese, and indigenous influences across the continent. In Spanish-speaking regions, the generic term "zorro" (fox) is widely used, originating from the Spanish word for fox, which entered the language around the 15th century and became associated with these canids through colonial documentation.^[8] In Portuguese, they are known as "raposa," directly translating to fox. Species-specific names often draw from indigenous languages; for instance, the culpeo (Lycalopex culpaeus) derives from the Mapudungun (Mapuche) term "culpeu" or "culpem," meaning "madness" and referring to its bold behavior toward hunters.^[9] Similarly, the South American gray fox (Lycalopex griseus), called "chilla," stems from the Mapudungun word "chilla," simply meaning "fox." Darwin's fox (Lycalopex fulvipes) holds cultural significance in Mapudungun as "payne guru," where "payne" refers to fox and "guru" to blue or dark, evoking its distinctive dark fur and tying into Mapuche folklore as a forest guardian.^[10] These indigenous terms underscore the foxes' integration into local ecosystems and narratives in pre-colonial South American cultures.

Species

The genus Lycalopex includes six extant species endemic to South America, all belonging to the family Canidae and characterized as "false foxes" due to their convergent evolution with true foxes in the genus Vulpes. These species exhibit varying body sizes, from small desert-adapted forms to larger montane ones, and recent phylogenetic analyses using mitochondrial and nuclear DNA have confirmed their monophyly, with divergence beginning approximately 1.2 million years ago during the Pleistocene.^[11] Genetic studies in the 2020s, including multilocus sequencing, have further validated the taxonomic separation of L. vetulus from true foxes, highlighting its basal position within Lycalopex and evidence of ancient hybridization events.^[11]

South American gray fox (L. griseus): This medium-sized species, also known as the chilla, features a brindled gray coat and large ears, with adults weighing 2–4 kg and total length up to about 1 m; it shows geographic variation, with two recognized forms—the Patagonian (L. g. griseus) in southern regions and the Andean (L. g. martinensis) in higher elevations—though subspecies status remains debated in recent taxonomy.^[12]^[13]
Culpeo or Andean fox (L. culpaeus): The largest species in the genus, reaching head-body lengths of 445–925 mm plus a tail of 305–493 mm, and weighing up to 14 kg, with a robust build and tawny to reddish-brown fur; it is widely distributed across the Andes and exhibits sexual dimorphism, with males larger than females.^[14]^[11]
Pampas fox (L. gymnocercus): A medium-sized canid weighing 4.2–6.5 kg and averaging 96 cm in total length, distinguished by its brindled gray back, reddish head and legs, and black muzzle extending to the mouth corners, unlike the culpeo.^[15]
Sechuran fox (L. sechurae): The smallest species overall, with adults weighing 2.6–4.2 kg and head-body lengths of 50–78 cm, featuring pale gray fur with yellowish tinges suited to arid environments; it is classified as Near Threatened due to habitat loss.^[16]^[11]
Darwin's fox (L. fulvipes): The smallest and most endangered species in the genus, with adults around 2.7 kg and total length of approximately 75 cm, notable for its black-and-gray fur with rufous markings on ears and legs; formerly considered a subspecies of L. griseus, it is now recognized as distinct and restricted to small populations in Chile.^[17]^[11]
Hoary fox (L. vetulus): A small species weighing 2.7–4 kg and totaling about 92 cm in length, with grayish fur accented by reddish legs and ears, a dark dorsal stripe, and broad molars adapted for an omnivorous diet; endemic to Brazil, its placement in Lycalopex has been genetically affirmed separate from Vulpes in recent analyses.^[18]^[11]

Phylogeny

The South American foxes, belonging to the genus Lycalopex, trace their evolutionary origins to the broader Canidae family, with the lineage leading to modern South American canids diverging from other canids approximately 4 million years ago during the Pliocene.^[19] This divergence occurred prior to the major phases of the Great American Biotic Interchange, allowing ancestral canids to migrate southward and evolve in relative isolation on the South American continent, adapting to diverse Neotropical environments over millions of years.^[2] Within the Canidae family, Lycalopex species are placed in the South American clade of the tribe Canini, which includes wolves (Canis) and other dog-like canids, rather than the Vulpini tribe containing true foxes (Vulpes). This phylogenetic positioning explains their designation as "false foxes," as they share closer genetic affinities with wolves and jackals despite superficial resemblances to northern foxes in morphology and behavior.^[2] Molecular studies from the 2010s and 2020s, utilizing mitochondrial DNA and nuclear markers, have confirmed the monophyly of the genus Lycalopex, with the six extant species radiating rapidly between approximately 1.4 and 0.8 million years ago during the Pleistocene.^[20] These analyses, including control region sequencing and whole-genome comparisons, position the hoary fox (L. vetulus) as the basal species within the genus, diverging earliest from the common ancestor and highlighting a pattern of recent, explosive diversification driven by climatic shifts and habitat fragmentation.^[21]^[2] The fossil record provides key insights into the genus's evolutionary history, with extinct relatives such as Dusicyon australis (the Falkland Islands wolf) from the Pleistocene (approximately 0.3-0.01 million years ago) demonstrating close links to modern Lycalopex species through shared cranial and dental features.^[22] This species, which persisted into the Holocene before extinction around 1876 CE due to human activities, represents a terminal branch of the South American canid radiation, underscoring the clade's vulnerability to environmental changes and anthropogenic pressures.^[23]

Physical characteristics

Size and build

South American foxes of the genus Lycalopex exhibit a wide range in body size, reflecting their diverse ecological niches across the continent. Head and body lengths typically range from 0.45 to 0.95 meters, excluding the tail, while weights vary between 2 and 14 kg.^[17]^[15]^[14] The culpeo (L. culpaeus) is the largest species, with head-body lengths up to 92.5 cm and weights reaching 14 kg, whereas Darwin's fox (L. fulvipes) is the smallest, measuring about 52.8 cm in head-body length and weighing around 2.7 kg.^[14]^[17] These foxes share a characteristic build suited to agile movement, featuring elongated snouts for scent detection and probing, strong limbs that enable quick maneuvers, and bushy tails that comprise 30-50% of total body length to aid in balance during rapid turns and jumps.^[12]^[14]^[15] Sexual dimorphism is evident in most species, with males generally slightly larger and heavier than females; this difference is particularly pronounced in the culpeo, where males average 11.65 kg compared to 7.82 kg for females.^[14]^[15] Morphological adaptations in limb structure and paw robustness allow Lycalopex species to traverse varied terrains effectively. For instance, the pampas fox (L. gymnocercus) possesses cursorial legs optimized for fast locomotion across open plains, with muscle architecture prioritizing sagittal plane movements for speed and endurance.^[24] In contrast, the Sechuran fox (L. sechurae) has a more compact build and lighter body mass (2.6-4 kg), facilitating navigation in arid desert environments.^[25] Robust paws across the genus provide traction on loose soils and rocky substrates, enhancing stability in diverse landscapes.^[14]

Fur and coloration

South American foxes in the genus Lycalopex exhibit a dense pelage adapted for thermoregulation, consisting of a soft undercoat and coarser guard hairs that form a double-layered structure for insulation in diverse climates ranging from arid deserts to temperate forests.^[26]^[16] The undercoat molts seasonally, growing thicker and longer during winter months to enhance warmth, particularly in temperate species such as the culpeo (L. culpaeus), where the fur becomes notably denser to withstand cooler conditions.^[14] This adaptation is evident across the genus, with guard hairs featuring agouti patterns that contribute to the overall grizzled appearance.^[5] The coloration of Lycalopex species typically features a grizzled gray base with rufous or tawny accents, facilitating countershading that aids camouflage in open grasslands and forested environments by blending dorsal tones with surroundings and lighter ventral areas with shaded undergrowth.^[12] For instance, the South American gray fox (L. griseus) displays a brindled gray coat with reddish legs, flanks, and a black-tipped bushy tail, while the culpeo shows tawny sides, reddish-brown head and legs, and white underparts, with regional variations producing lighter northern forms.^[14]^[12] Species-specific variations further highlight adaptive pelage diversity. The hoary fox (L. vetulus) has a short, grayish coat interspersed with white or silvery hairs, reddish ears and legs, and a dark dorsal stripe along the back and tail for subtle patterning in savanna habitats.^[18] Darwin's fox (L. fulvipes), in contrast, possesses a darker pelage of mixed black and gray hairs with rufous markings on the ears and lower legs, complemented by white under the chin and along the belly, enhancing concealment in Chilean temperate rainforests.^[17] The pampas fox (L. gymnocercus) features a brindled gray back, paler gray underparts, reddish head, neck, and outer legs, with juveniles initially appearing nearly black before lightening.^[15] These patterns underscore the genus's versatility in visual adaptation across South American ecosystems.

Distribution and habitat

Geographic range

South American foxes of the genus Lycalopex are native to the continent of South America, with their collective range spanning from southwestern Colombia in the north to Tierra del Fuego in the extreme south, encompassing diverse ecosystems but notably excluding the core of the Amazon basin where no species occur.^[27]^[2] The genus is entirely endemic to this region, with no confirmed introduced populations outside South America, though the South American gray fox (L. griseus) was intentionally released on the Falkland Islands in 1951 to control invasive rabbits and has since established a feral population there.^[28] Specific country distributions vary by species, reflecting adaptations to regional landscapes. For instance, the culpeo (L. culpaeus) occupies a broad swath across Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina, often along the Andean cordillera and extending eastward into Patagonian steppes.^[27] In contrast, Darwin's fox (L. fulvipes) is highly restricted, endemic solely to Chile where it inhabits fragmented temperate forests on Chiloé Island and the mainland Nahuelbuta Range.^[10] The pampas fox (L. gymnocercus) is widespread in the Southern Cone, including eastern Bolivia, Paraguay, Uruguay, central and northern Argentina, and southeastern Brazil.^[29] The South American gray fox (L. griseus) ranges through southern Peru, Chile, and Argentina, primarily in Patagonia on both sides of the Andes.^[28] The Sechuran fox (L. sechurae) is confined to coastal arid zones in southwestern Ecuador and northwestern Peru.^[30] Finally, the hoary fox (L. vetulus) is limited to central and eastern Brazil, particularly the Cerrado biome.^[7] Altitudinal variation further defines these ranges, with species like the culpeo inhabiting elevations from sea level up to approximately 5,000 m in the high Andes of Peru, Bolivia, Chile, and Argentina, enabling it to exploit montane shrublands and puna grasslands.^[27] The Sechuran fox, however, remains strictly coastal and low-elevation, rarely exceeding 500 m and confined to desert and thorn-scrub habitats along the Pacific seaboard.^[30] Historically, European settlement in the 19th and early 20th centuries led to range contractions for several Lycalopex species through habitat conversion for agriculture and livestock ranching, coupled with intense persecution as perceived threats to introduced ungulates like sheep and cattle.^[27] For example, culpeo populations declined markedly in Andean valleys and Patagonian lowlands due to bounties and poisoning campaigns.^[31] However, 20th-century records indicate recoveries and expansions in some areas, such as the pampas where the pampas fox has benefited from increased open habitats and abundant prey like European hares (Lepus europaeus), leading to genetic signals of population growth.^[2]^[29]

Preferred habitats

South American foxes, belonging primarily to the genus Lycalopex, occupy a wide array of ecosystems across the continent, reflecting their ecological versatility within the Canidae family. These species generally favor open and semi-open landscapes that provide cover and prey availability, ranging from arid deserts to temperate woodlands. For instance, the pampas fox (Lycalopex gymnocercus) thrives in expansive grasslands, tall grass plains, and sub-humid to dry savannas, often utilizing sierras and narrow wooded strips along streams for additional shelter.^[15]^[29] Similarly, the Sechuran fox (Lycalopex sechurae) is specialized for extreme aridity, inhabiting coastal deserts, dry forests, and sandy beaches along the western Andes foothills, where sparse vegetation supports its survival.^[25]^[16] Microhabitat selection among these foxes emphasizes transitional zones that balance exposure and protection. The South American gray fox (Lycalopex griseus) preferentially occupies forest edges, low open grasslands, and pampas adjacent to foothills, creating opportunities for denning in sandy soils or rock crevices.^[12] Darwin's fox (Lycalopex fulvipes), in contrast, confines itself to dense, second-growth temperate rainforests of Valdivian type on Chiloé Island and mainland Chile, favoring understory thickets within Nothofagus and Araucaria forests for concealment.^[17] The culpeo or Andean fox (Lycalopex culpaeus) exploits elevational gradients, from coastal plains and deserts to high-altitude montane shrublands in the Andes.^[27] Adaptability to altered environments enhances their persistence, though they typically shun dense, closed-canopy rainforests. The hoary fox (Lycalopex vetulus) tolerates human-modified landscapes, including pastures, farmlands, and woodland-savanna edges in the Cerrado biome, where it navigates fragmented habitats without venturing into humid tropical forests.^[18] Climate plays a pivotal role, with most preferring semi-arid to temperate regimes; Andean species such as the culpeo exhibit elevational shifts to track seasonal temperature and precipitation variations, maintaining presence from sea level to over 4,000 meters.^[29]

Behavior and ecology

Diet and foraging

South American foxes of the genus Lycalopex are omnivores, with diets dominated by animal matter but supplemented by plant material. Small mammals, particularly rodents and lagomorphs, typically constitute 60-80% of their consumed biomass in most species, reflecting their role as opportunistic predators in diverse ecosystems, though the hoary fox relies heavily on insects. The remaining portion, roughly 20%, consists of fruits, seeds, and invertebrates such as insects and arthropods, allowing flexibility in response to prey availability. For instance, in the culpeo fox (Lycalopex culpaeus), small mammals account for about 41% of the diet, lagomorphs 21%, and invertebrates 12%, with occasional inclusion of larger prey like guanacos through predation or scavenging of carrion.^[32]^[14]^[33] Foraging activity is predominantly nocturnal or crepuscular, enabling these foxes to exploit low-light conditions for hunting while minimizing encounters with diurnal competitors. They employ stalking and pouncing techniques to capture small, elusive prey like rodents, often listening for subsurface movements before leaping to subdue them. Near human settlements, they opportunistically scavenge refuse or livestock remains, supplementing natural foraging with anthropogenic food sources.^[34]^[35] Dietary composition varies seasonally, with shifts toward increased frugivory in some species during resource-scarce periods; for the hoary fox (Lycalopex vetulus), fruit consumption rises in the wet season alongside other insects and small mammals. Studies of sympatric species reveal dietary overlap but also niche partitioning, where differences in prey size or type—such as the culpeo's preference for larger herbivores versus the gray fox's (Lycalopex griseus) focus on smaller rodents and lagomorphs—facilitate coexistence. Their digestive systems feature short intestines optimized for rapid processing of high-protein carnivorous meals. Some species cache excess food to buffer against fluctuations in availability. Habitat structure influences prey abundance, subtly shaping these foraging patterns without altering core strategies.^[18]^[36]

Reproduction and life cycle

South American foxes in the genus Lycalopex typically form monogamous pairs that remain together for breeding and often beyond, with mating occurring once annually during the late winter to early spring in the Southern Hemisphere, generally from August to October.^[37] Gestation lasts 50–60 days across species, after which females give birth to litters of 2–7 pups in underground dens or burrows, where the altricial young are born blind, deaf, and dependent on parental care.^[37] Both parents contribute to rearing, with females providing milk and males assisting in provisioning and protection, though the extent of paternal involvement varies.^[14] Pups emerge from the den after 4–6 weeks and are weaned at 2–3 months, transitioning to solid food while remaining under parental supervision.^[12] Independence is achieved around 6–8 months, when juveniles disperse to establish their own territories, and sexual maturity is reached at approximately 1 year of age.^[14] Juvenile mortality is high, primarily due to predation by larger carnivores such as pumas or birds of prey during the vulnerable early stages.^[37] Species-specific variations exist; for instance, Darwin's fox (L. fulvipes) produces the smallest litters of 1–3 pups, reflecting its endangered status and limited resources in its restricted habitat. In the culpeo (L. culpaeus), biparental care is pronounced, with males actively guarding the territory and den against intruders to safeguard the family unit.^[17]^[14] Lifespan in the wild averages 5–10 years, influenced by predation and environmental factors, while individuals in captivity can live up to 15 years under protected conditions.^[14] South American foxes in the genus Lycalopex exhibit predominantly solitary lifestyles, forming monogamous pairs that maintain year-round territories as the core of their social structure. Outside of the breeding season, individuals forage and rest alone, but during pup-rearing, family groups comprising the breeding pair and their offspring temporarily coalesce to provide cooperative care. For instance, in the South American gray fox (L. griseus), breeding pairs serve as the social nucleus, occasionally augmented by subordinate females that assist in rearing without producing litters of their own. Similarly, the culpeo (L. culpaeus) is solitary except when pairs associate for reproduction and offspring care, with territories sometimes shared among related individuals.^[12]^[14] Communication among these foxes relies on multimodal signals to regulate interactions and maintain spatial separation. Vocalizations, including barks for territorial warnings and howls for long-distance contact, are prominent, particularly during encounters with intruders. Scent marking via urine and feces deposits boundaries and advertises presence, while visual cues such as tail postures signal dominance or submission during brief conspecific meetings. These behaviors facilitate minimal direct contact, emphasizing avoidance over confrontation.^[14]^[38] Territoriality structures their social dynamics, with home ranges defended primarily by males to secure resources and mates. Range sizes vary by species, sex, and habitat quality, typically spanning 1–10 km² but extending to 50 km² in resource-poor arid zones; for example, culpeo females occupy 6–9 km² and males 2–10 km² in semi-arid Chilean landscapes. In the pampas fox (L. gymnocercus), female ranges show considerable overlap, particularly with males, allowing flexible resource sharing without intense competition, while core areas remain exclusive. Interactions between conspecifics involve low levels of aggression, as individuals generally avoid overlap to reduce conflict, though brief chases or displays occur at boundaries.^[39]^[31]^[40]

Conservation and human interaction

Threats and status

The conservation status of South American foxes varies across species within the genus Lycalopex, with most classified as Least Concern by the IUCN Red List, reflecting their adaptability and wide distributions, though regional declines occur due to anthropogenic pressures. Darwin's fox (L. fulvipes) is Endangered, with an estimated population of fewer than 1,000 mature individuals confined to fragmented forests in southern Chile. The hoary fox (L. vetulus) and Sechuran fox (L. sechurae) are Near Threatened, experiencing ongoing declines from habitat loss and other factors. The culpeo (L. culpaeus), South American gray fox (L. griseus), and pampas fox (L. gymnocercus) are globally Least Concern, but the culpeo faces localized threats leading to population reductions in parts of its Andean range. Primary threats to South American foxes include habitat fragmentation driven by agricultural expansion, which has converted significant portions of their native grasslands, shrublands, and forests into croplands and pastures, isolating populations and reducing genetic diversity. Hunting for fur and as perceived livestock predators remains a concern, particularly for the culpeo and South American gray fox, where retaliatory killings occur despite legal protections in some countries. Roadkill is increasingly problematic, especially for species like the pampas fox along expanding road networks in southern Brazil and Argentina. Additionally, diseases transmitted from domestic dogs, such as canine distemper virus and rabies, pose risks to vulnerable populations like Darwin's fox through spillover in human-dominated landscapes. Population trends are stable for widespread species like the South American gray fox, with a large population across Patagonia, benefiting from its opportunistic habits. In contrast, the Sechuran fox is declining due to desertification and habitat degradation in coastal Peru and Ecuador. Darwin's fox populations persist at low levels, with estimates around 639 adults as of 2021, highlighting the urgency of targeted interventions. Conservation efforts focus on protected areas and species-specific actions to mitigate threats. The culpeo benefits from habitats in reserves like Torres del Paine National Park in Chile, where anti-poaching measures and habitat restoration support stable subpopulations. For Darwin's fox, ongoing initiatives include national action plans developed in the 2020s, emphasizing disease monitoring, habitat connectivity, and genomic studies to enhance genetic diversity, including recent 2025 research on population genomics, though formal reintroduction trials remain in early planning stages. Broader strategies across species involve reducing human-wildlife conflict through livestock guarding programs and expanding protected networks in agricultural frontiers.

Relationship with humans

In Andean folklore among Quechua and other indigenous groups, the fox, known as zorro, often appears as a cunning trickster figure, embodying deceit and greed in tales that parallel the coyote's role in North American Native myths.^[41] For instance, in Aymara stories like "Fox and Monkey," the fox employs sly tactics to outwit other animals, reinforcing its reputation as a thieving scoundrel whose sighting is viewed as an ill omen.^[41] This archetype indirectly influences popular culture, as seen in the Zorro literary and media franchise, where the masked hero's name evokes the fox's elusive and clever nature.^[42] Throughout the 19th and 20th centuries, South American foxes, particularly the culpeo (Lycalopex culpaeus), faced significant persecution in Patagonia due to their occasional raids on poultry and livestock, leading to widespread hunting by farmers.^[27] The fur trade further intensified exploitation, with culpeo pelts heavily harvested across their range until regulations curtailed international commerce in the late 20th century.^[27] Today, such trade is strictly controlled under CITES appendices, reflecting a shift toward conservation amid declining demand.^[27] In contemporary contexts, South American foxes serve as key attractions in ecotourism initiatives in Chile and Argentina, where sightings of species like the gray fox (Lycalopex griseus) in Patagonian landscapes draw wildlife enthusiasts to protected areas. Guided tours in regions such as Torres del Paine National Park highlight their elusive behaviors, promoting habitat preservation through visitor revenue.^[43] Research has also documented urban adaptation, with gray foxes exhibiting high ecological plasticity in Buenos Aires suburbs, where they navigate human-modified environments while avoiding domestic dogs.^[44] Human-fox conflicts primarily stem from perceived livestock predation, though the culpeo fox's diet is dominated by native rodents and lagomorphs, with livestock forming a minor component in many Patagonian and central Argentine sites. Since the 2010s, mitigation efforts have emphasized non-lethal deterrents, including guard dogs and light-based repellents, which have proven effective in reducing attacks on sheep and alpacas without resorting to lethal control.^[45] These strategies, promoted by conservation organizations, encourage coexistence by addressing farmer concerns while safeguarding fox populations.^[32]
