Living on the edge: regional distribution and retracting range of the jaguar (Panthera onca) [PDF]

, 2017
Vivir al límite: distribución regional y superficie ocupada por el jaguar en retroceso (Panthera onca) Para conservar la biodiversidad, es necesario entender cómo se distribuyen las especies y qué variables ambientales determinan dicha distribución ...

Density and habitat use of one of the last jaguar populations of the Brazilian Atlantic Forest: Is there still hope?

Ecology and Evolution, 2022
The jaguar (Panthera onca) plays an important role in maintaining biodiversity and ecological processes. We evaluated the status of a jaguar population in one of the last stronghold habitats for its conservation in the Atlantic Forest, the Rio Doce State

The GREATS H$\beta$+[OIII] Luminosity Function and Galaxy Properties at $\mathbf{z\sim8}$: Walking the Way of JWST [PDF]

, 2019
The James Webb Space Telescope will allow to spectroscopically study an unprecedented number of galaxies deep into the reionization era, notably by detecting [OIII] and H$\beta$ nebular emission lines.

Jaguar Persecution Without “Cowflict”: Insights From Protected Territories in the Bolivian Amazon

Frontiers in Ecology and Evolution, 2019
Persecution by humans is one of the most pressing threats to jaguars (Panthera onca) throughout the Americas, yet few studies have examined the killing of jaguars outside cattle-ranching communities.

Investigating screen complexity in the vehicle, how does design effect driver attention and task performance?

Computers in Human Behavior Reports
Digital systems can encourage information overload, and the driving environment is not immune to this. In-vehicle displays are increasing in functional and informational complexity, which can lead to increased workload if not designed appropriately for ...

Aminomethanol water elimination: Theoretical examination [PDF]

, 2005
The mechanism for the formation of hexamethylenetetraamine predicts the formation of aminomethanol from the addition of ammonia to formaldehyde. This molecule subsequently undergoes unimolecular decomposition to form methanimine and water.

Jaguar interactions with pumas and prey at the northern edge of jaguars’ range

PeerJ, 2017
We present the first study that evaluates jaguar-puma interactions in the arid lands of northern Mexico, where jaguars have their northernmost breeding population and both predators are persecuted for livestock depredation. We tested whether jaguars are the dominant species in this unique ecosystem, where: (1) pumas outnumber jaguars, (2) pumas are ...

Estimating large carnivore populations at global scale based on spatial predictions of density and distribution - Application to the jaguar (Panthera onca). [PDF]

PLoS ONE, 2018
Broad scale population estimates of declining species are desired for conservation efforts. However, for many secretive species including large carnivores, such estimates are often difficult.

The Use of Camera Traps and Auxiliary Satellite Telemetry to Estimate Jaguar Population Density in Northwestern Costa Rica

Animals, 2022
Regular evaluation of jaguar (Panthera onca) population status is an important part of conservation decision-making. Currently, camera trapping has become the standard method used to estimate jaguar abundance and demographic parameters, though evidence ...
