The mortality of wildlife due to vehicle collisions is a poorly studied problem. In Mexico, interest in determining the negative effects and mitigation actions regarding the impact of road networks on wild vertebrate populations has increased. This study documents two cases of the apparent run over of an individual of jaguarundi and one of tigrillo, on state highways in the central coastal region of the state of Yucatán, Mexico. Both records show the importance of studies that quantify the collision of vertebrates on roads to plan its mitigation.
... Aunque para el estado de Jalisco ya existen registros previos de al menos dos ejemplares de jaguarundis atropellados (González-Gallina & Hidalgo-Mihart 2018), este es el primer registro publicado para la región de Puerto Vallarta. Así, esta región se suma a las localidades mexicanas con mayor número de atropellamientos, entre uno a cuatro eventos, ubicadas en los estados de la costa centro y sur del Pacífico, la península de Yucatán y el noreste ( La apariencia del ejemplar atropellado se apega a las características comunes a los de su especie con relación al pelaje y talla (de Oliveira 1998, Ceballos & Miranda 2000, da Silva et al. 2016. Asimismo, su observación en la zona revalida otros aspectos ya conocidos para este carnívoro: realización de actividades diurnas, habitante del bosque tropical subcaducifolio (de Oliveira 1998, Aranda 2005, Botello et al. 2013, Urrea-Galeano et al. 2016, y capacidad para vivir en áreas con vegetación secundaria (Aranda & Caso 2014). ...

... Similarly, in the Brazilian pampa, jaguarundis consumed small mammals, birds, and reptiles in similar proportions to the jaguarundis at RNBM (Migliorini et al. 2018). Generally, the results from this study were consistent with those from other studies and were representative of the overall diet for the species throughout its range (Oliveira 1998a). ...

Mammalian carnivore diversity within the Reserva Natural del Bosque Mbaracayú in eastern Paraguay is represented by five families (Canidae, Mephitidae, Mustelidae, Procyonidae, and Felidae) and includes large-bodied, apex predators, several omnivores, and numerous mesocarnivores. The competitive exclusion principle argues that sustained spatial and temporal coexistence of two or more species with identical ecological requirements is unsustainable. The Reserve is a mosaic of habitats that has become isolated due to extensive deforestation of the surrounding Upper Paraná Atlantic Forest. Nevertheless, it is remarkable in that 16 mammalian carnivore species are documented as coexisting within the Reserve. We sought to determine the extent to which this diverse community is mitigating competition through the partitioning of available niche space by assessing dietary ecology of mammalian carnivores present, including diet breadths and dietary overlap, and by examining spatial patterns within the reserve. Feces were collected from all 16 mammalian carnivore species from seven areas within the reserve and specific identifications were confirmed by molecular analyses. Diet breadth, B^, standardized diet breadth, B^A, and Pianka’s Index for dietary overlap, O^, were calculated. A Chi-square goodness-of-fit test was performed to test for randomness of samples associated with survey areas. Diet analyses indicated a spectrum from dietary generalists to specialists. Species segregated into six dietary guilds, defined as groups of species with O^ > 0.5. Four guilds included only one species each (Neotropical otter, crab-eating fox, jaguar, and puma). The low dietary overlap between jaguar and puma contrasts with studies conducted elsewhere. One guild consisted of four highly omnivorous species (maned wolf, Molina’s hog-nosed skunk, crab-eating raccoon, and South American coati). The sixth guild included eight species which mostly consumed small vertebrates, primarily mammals as well as birds and reptiles (bush dog, two mustelines, five small felids). The mustelines (tayra and lesser grison) had extremely high dietary overlap. Although they did not segregate spatially, they are known to occupy distinct niches in vertically stratified forests. The five small felids also showed extremely high dietary overlap. Three of them were found to segregate spatially within the Reserve and two did not, although one (jaguarundi) is known to segregate temporally, being more active diurnally. The exceptionally rich community of mammalian carnivore species at the Reserva Natural del Bosque Mbaracayú appeared to avoid unsustainable competition by a variety of mechanisms, some utilizing different food items, or, in the case of high dietary overlap, utilizing spatial or temporal resources differently.
... The body is slight, with a long back, long slender tail, long neck, and short limbs (Emmons and Feer 1997). The head is flat, elongated, and low, with small, rounded ears (Oliveira 1998). Its mustelid-shaped body resembles the Tayra (Eira barbara) but is distinguishable by its long and thin tail and lack of a pale spot on the throat. ...

The Atlantic Forest is one of the most biodiverse biomes in the world and has been severely degraded and fragmented, with the extirpation of most medium-sized and large vertebrates from the forest remnants. Here we present the results of a survey of medium-sized and large mammals in an area of protected seasonal semideciduous forest, the Floresta da Cicuta Area of Relevant Ecological Interest (ARIE-FC), Rio de Janeiro, Brazil, part the Atlantic Forest biome. We used camera traps (2,257 camera days) and direct observations over a 23-month period. We recorded 19 species (including two domestic species), seven of which are classified as at-risk, such as Leopardus guttulus (Hensel, 1872), Sylvilagus tapetillus Thomas, 1913, Alouatta clamitans Cabrera, 1940, and Chrysocyon brachyurus (Illiger, 1815). A diverse terrestrial mammal assemblage in the ARIE-FC reinforces the importance of small forest fragments for the conservation of biodiversity in human-modified landscapes of the Brazilian Atlantic Forest.
... The species ranges from the southwestern United States, through Central America and much of South America, reaching as far as northern Argentina. Within this range, jaguarundis inhabit a wide variety of habitats, from semi-arid and grassland areas to dense dry and wet forests (de Oliveira 1998;Espinosa et al. 2017). Jaguarundis display differences in craniodental morphology as well as 2 primary pelage colors (gray or dark versus reddish) across these heterogeneous habitats, which has led to the definition of as many as 8 subspecies (Allen 1919;Cabrera 1958). ...

The Puma lineage within the family Felidae consists of three species that last shared a common ancestor around 4.9 million years ago. Whole-genome sequences of two species from the lineage were previously reported: the cheetah (Acinonyx jubatus) and the mountain lion (Puma concolor). The present report describes a whole-genome assembly of the remaining species, the jaguarundi (Puma yagouaroundi). We sequenced the genome of a male jaguarundi with 10X Genomics linked reads and assembled the whole-genome sequence. The assembled genome contains a series of scaffolds that reach the length of chromosome arms and is similar in scaffold contiguity to the genome assemblies of cheetah and puma, with a contig N50 = 100.2 kbp and a scaffold N50 = 49.27 Mbp. We assessed the assembled sequence of the jaguarundi genome using BUSCO, aligned reads of the sequenced individual and another published female jaguarundi to the assembled genome, annotated protein-coding genes, repeats, genomic variants and their effects with respect to the protein-coding genes, and analyzed differences of the two jaguarundis from the reference mitochondrial genome. The jaguarundi genome assembly and its annotation were compared in quality, variants and features to the previously reported genome assemblies of puma and cheetah. Computational analyzes used in the study were implemented in transparent and reproducible way to allow their further reuse and modification.

When the top predators such as the jaguar and the puma have disappeared or their numbers have decreased, an increase in the populations of mesopredators such as the ocelot is common, which in turn causes a decrease in the predator species of smaller size, or a modification of their activity patterns, a phenomenon known as the “pardalis effect”. It has not been documented how common this phenomenon is or its variations. The objective of this study is to characterize the pardalis effect and its variation in a cloud forest, a pine forest and an anthropized area, and the effect of human activities on it in Oaxaca, southeastern Mexico. Abundance was estimated and the activity patterns of the feline species were characterized by photo-trapping. Two hundred seventy independent photographic records of 5 feline species were obtained. Density for all species differed significantly between types of vegetation cover. No significant differences were found among seasons or among types of vegetation cover for the top predators and the ocelot, but among types of plant cover for felines of smaller size. The pardalis effect was only observed in the anthropized area.

In today’s increasingly degraded world, private lands are becoming integral components of wildlife conservation. The Caatinga biome possesses the largest tropical dry forest in the Americas; however, it has experienced high levels of habitat loss. Natural vegetation cover in this biome is highly fragmented, and the few protected areas tend to be privately-owned. In this context, carnivores are particularly vulnerable to anthropogenic threats. Identifying factors that influence carnivore habitat selection in privately-owned areas is crucial for effective conservation actions. To this end, we assessed the habitat preferences of northern tiger cats (Leopardus tigrinus), jaguarundis (Herpailurus yagouaroundi), crab-eating foxes (Cerdocyon thous), and crab-eating raccoons (Procyon cancrivorus) on a private reserve in the Caatinga. We sampled the area with camera traps during a 4-year period and examined habitat use patterns through occupancy models. Caatinga cover was strongly favoured by northern tiger cats. Areas near human household had higher jaguarundi occupancy and crab-eating fox detection. Edge effects did not influence any of the species. The results suggest that in the absence of poaching and provided there is enough natural vegetation cover left, private lands indeed have potential conservation value for some carnivorous species. Nevertheless, because these areas tend to be small, connectivity with larger habitat patches is important for long-term conservation.

The jaguarundi (Puma yagouaroundi) is a small felid with a historical range from central Argentina through southern Texas. Information on the current distribution of this re-clusive species is needed to inform recovery strategies in the United States where its last record was in 1986 in Texas. From 2003 to 2021, we conducted camera-trap surveys across southern Texas and northern Tamaulipas, México to survey for medium-sized wild cats (i.e., ocelots [Leopardus pardalis], bobcats [Lynx rufus], and jaguarundi). After 350,366 trap nights at 685 camera sites, we did not detect jaguarundis at 16 properties or along 2 highways (1050 km 2) in Texas. However, we recorded 126 jag-uarundi photographic detections in 15,784 trap nights on 2 properties (125.3 km 2) in the northern Sierra of Tamaulipas, Tamaulipas, México. On these properties, latency to detection was 72 trap nights, with a 0.05 probability of detection per day and 0.73 photographic event rate every 100 trap nights. Due to a lack of confirmed class I sightings (e.g., specimen, photograph) in the 18 years of this study, and no other class I observations since 1986 in the United States, we conclude that the jaguarundi is likely extirpated from the United States. Based on survey effort and results from México, we would have expected to detect jaguarundis over the course of the study if still extant in Texas. We recommend that state and federal agencies consider jaguarundis as extirpated from the United States and initiate recovery actions as mandated in the federal jaguarundi recovery plan. These recovery actions include identification of suitable habitat in Texas, identification of robust populations in México, and re-introduction of the jaguarundi to Texas.

Puma (Puma concolor) coexists with bobcat (Lynx rufus) in Tehuacán-Cuicatlán Biosphere Reserve (RBTC). Because P. concolor is the largest feline in central México, puma's presence is an indicator of ecological integrity. Our objective was to compare puma and bobcat density in a conserved area within the reserve. We deployed 15 camera stations along the ridge and a dry riverbed in Mount Tepetroja in tropical dry forest. To estimate population density, we used capture-recapture models and analyzed images from 1 May 2013 to 30 April 2017 with MARK software and CAPTURE tool. For puma, we obtained a density of 6.8 ind/100 km2 in an effective trapping area (ETA) of 70 km2, and a mean maximum distance moved (MMDM) of 2.46 ± 0.45 km. For bobcat, our population density estimate (15.4 ind/100 km2 in ETA of 38 km2) and MMDM (1.76 ± 0.41 km) is the first for central Mexico in conserved native vegetation. Puma abundance was lower compared to bobcat abundance in the reserve’s tropical dry forest; therefore, we infer that the wild felids' density is determined by their body size in an ecosystem with ecological integrity. Key words: Abundance; Felidae; Felid; Photo-capture; Capture-recapture model; Tropical dry forest
