Ecological modeling, biogeography, and phenotypic analyses setting the tiger cats’ hyperdimensional niches reveal a new species

Abstract Recently, the tiger-cat species complex was split into Leopardus tigrinus and guttulus , along with other proposed schemes. We performed a detailed analysis integrating ecological modeling, biogeography, phenotype of four originally recognized subspecies— oncilla pardinoides —and presented new multidimensional niche depiction species. Species distribution models used > 1400 records from museums photographs, all checked for accuracy. Morphological data were obtained institutional/personal archives. Spotting patterns established by museum photographic/camera-trap records. Principal component showed three clearly distinct groups, Central American specimens ( ) clustering entirely within those Andes, namely group cloud forests southern Central-American Andean mountain chains (clouded tiger-cat); savannas Guiana Shield central/northeastern Brazil (savanna in lowland Atlantic Forest domain (Atlantic tiger-cat). This scheme is supported recent genetic analyses. All displayed different spotting patterns, some significant differences body measurements/proportions. The alarming reductions historic range − 50.4% to 68.2%. approach revealed elusive threatened complex.

Mediante fototrampeo documentamos la presencia de Leopardus pardinoides en quebrada del río Huangal, valle interandino, al oriente Pifo, provincia Pichincha, Ecuador. El hallazgo subraya necesidad evaluar el impacto expansión industrial y agrícola sobre biodiversidad, ya que este felino habita cerca áreas pobladas por ser humano.

Howling shadows: First report of domestic dog attacks on globally threatened mountain tapirs in high Andean cloud forests of Colombia

Neotropical Biology and Conservation, Journal Year: 2024, Volume and Issue: 19(1), P. 25 - 33

Domestic dogs ( Canis lupus familiaris ) are recognised worldwide not only as man’s best friend, but also a form of anthropogenic edge effect impacting wildlife through predation, competition and disease infection. In the Northern Andes, there is growing evidence inducing activity shifts or alterations in habitat use native mammalian species. However, little information exists on direct attacks wildlife, even case species conservation concern such mountain tapir Tapirus pinchaque ). Here, we used camera traps to report two cases chasing attacking tapirs protected area Central Andes Colombia. The first event showed physical contact between living adult dogs, picture’s angle did lead observable signs wounds other injuries. second an running while being chased by same event, denoting stressful moment for tapir. This may have negative consequences populations decreased reproductive performance foraging efficiency, increased potential outbreaks more. Population management control domestic inside around areas must be considered priority future actions support healthy population imperilled region.

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

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
