Potential distribution of the oncilla <em>Leopardus tigrinus</em> (Carnivora: Felidae) based on high-resolution spatial data and camera traps in a national park in Peru

Journal of Animal Behaviour and Biometeorology, Journal Year: 2025, Volume and Issue: 13(1), P. 2025007 - 2025007

Published: May 9, 2025

Potential species distribution models (SDMs) are typically evaluated over large territories via low-resolution spatial data and biased presence records. The Parque Nacional de Tingo María (National Park; PNTM, by their initials in Spanish), a small territory, presents challenges for this type of study. This study aimed to analyze the SDM an oncilla (Leopardus tigrinus) evaluate most influential specific areas. Maxent (Maximum Entropy) algorithm was used with 32 high-resolution layers derived from PlanetScope multispectral satellite image, DEM, bioclimatic, social, infrastructure variables, resampled 4.5 m resolution, along 13 records camera traps. zones were overlaid identify species' habitat. model has AUC 0.992, covering 54 hectares, favoring areas coldest quarter precipitation (Bio 19), dense vegetation (NDVI), avoiding roadways lower elevations. is located Buffer Zones (72.06%), Strict Protection (3.93%), Recovery (3.41%), Special Use (0.54%), Tourist Zone I (10.66%), II (0%), Wilderness (9.4%). viability spaces precise, highlighted. current zoning PNTM may not be sufficient protect critical habitats species.

Distribution and habitat use patterns of the endangered Central American clouded oncilla (Leopardus pardinoides oncilla) in Costa Rica

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(9), P. e0310562 - e0310562

Published: Sept. 17, 2024

Montane cloud forests are highly threatened ecosystems that vulnerable to climate change. These complex habitats harbor many species suffer the negative consequences of this global phenomenon, such as shifts in their distribution and habitat use. The Central American clouded oncilla ( Leopardus pardinoides ) is smallest most endangered wild cat Mesoamerica primarily reported throughout its distribution. poorly understood, with no studies conducted America assessing preferences. To bridge knowledge gap, we sampled two mountain ranges Costa Rica camera traps an occupancy analysis understand anthropogenic environmental features influence use within them. Additionally, spatial predictions across northern southern range identify priority conservation areas for species. We found driven by factors. Our results showed oncillas select denser tree cover at high elevations, closer permanent water sources, which may provide them prey density a favorable structure survival. Spatial identified main regions where threat mitigation efforts monitoring should be implemented: Caribbean slope Talamanca mountains, Arenal-Monteverde forest complex. modeling approach turned out very useful assess associations environment mapping areas. Future research actions focus on potential threats could negatively impact populations use, including role mesopredators feral

Shadows in the forest: Uncovering unusual colouration records in mammals from the Ecuadorian Tropical Andes

Biodiversity Data Journal, Journal Year: 2024, Volume and Issue: 12

Published: Nov. 20, 2024

Variations in colouration patterns have been reported numerous wildlife species, particularly birds. However, the increased use of camera traps for monitoring has enabled detection elusive species and phenotypic variations that might otherwise go undetected. Here, we compiled records unusual terrestrial mammals, documented through camera-trap studies over a 12-year period Llanganates-Sangay Connectivity Corridor, Tropical Andes Ecuador. We identified colour seven including disorders, such as melanism, white spotting/ piebaldism, xanthocromism progressive greying. Notably, high prevalence melanism wild populations clouded oncilla, along with observations on species' activity patterns. Approximately half recorded oncillas were melanistic. detected significant differences activty between melanistic non-melanistc morphs showing peak 3 a.m. before dawn. The proportion individuals suggests is widespread throughout corridor. its impact fitness remains unclear.

Infection Frequency and Allelic Variants of Toxoplasma gondii in Wildlife from the Panama Canal Zone

Microbiology Research, Journal Year: 2024, Volume and Issue: 15(4), P. 2035 - 2047

Published: Oct. 4, 2024

Panama has a large number of wild animal species, which could host highly diverse amount genetic variants Toxoplasma gondii (T. gondii). In this context, we highlight the importance understanding population structure T. in Panamanian wildlife and that can be rapidly transferred to domestic environments. This study analyzed infection frequency allelic composition different tissue samples from animals. The was measured by PCR technique using B1 gene as molecular marker. results showed high (65.6%) collected 221 Stratified analyses for bird mammal positivity rates 67.2% 70.12%, respectively, with no statistically significant differences. Infection also five types organs (brain, liver, heart, lung, skeletal muscle), homogeneous frequencies. diversity contained tissues animals Multilocus Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) technique, genes called SAG1, SAG2, SAG3, GRA6, Apico. analysis revealed presence alleles these corresponding lineages I, II, III. Allele III only identified Apico single reptile individual analyzed. Our findings indicated distribution at loci, suggesting were probably infected non-archetypal individuals gondii.

From single species to communities: microsatellite amplicon sequencing to monitor felids using Feliplex

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 23, 2024

Abstract The current biodiversity crisis demands a shift from single-species to multispecies approaches in conservation, particularly for rare and endangered species. However, this transition requires tools optimised research, which are currently limited. Recent advances high-throughput sequencing (HTS) technologies bioinformatics have enabled efficient robust acquisition of genetic data. Amplicon approaches, particular, demonstrated potential enhancing non-invasive studies species, but their application has been mostly limited single To enable we introduce cost-effective HTS-based amplicon approach genotyping multiple species simultaneously, designed population monitoring, including individual identification ascertaining patterns structure. We developed Feliplex, multiplex panel 85 co-amplifying tetranucleotide microsatellite markers cross-genotyping Felidae demonstrate the utility our approach. Feliplex was validated on known samples nine Indian felid across genera Panthera, Prionailurus , Felis . applied it invasive (blood tissue) (hair faeces) DNA extracts 173 wild individuals obtaining respectively 70% 56% multilocus success rates. accurately identified clusters tigers ( Panthera tigris n=19) revealed hitherto unknown structure fishing cats viverrinus n=40). Feliplex’s wide applicability allows reliable low-quality/quantity samples, while supporting conservation monitoring lesser-known like small cats. Our broad can be adapted develop similar panels closely related groups.
