Hambre cero y conservación de la biodiversidad. Desafíos para la conservación de depredadores tope y la ganadería sostenible en Latinoamérica

Naturaleza y Sociedad: Desafíos Medioambientales, 2022
La conservación de la biodiversidad y el desarrollo de la ganadería no han ido de la mano en Latinoamérica. Por un lado, la ganadería tiene como prioridad proveer proteína de origen animal a las comunidades locales; y, por otro, el creciente cambio de ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

野生动物对生态旅游的习惯化:哥斯达黎加科尔科瓦多国家公园中的COVID‐19封锁实验

Wildlife Letters
Corcovado National Park (CNP) in Costa Rica is an important destination for ecotourism. However, the effects of increasing human visitation on wildlife needed evaluation and the global COVID‐19 pandemic lockdown provided a scenario to test the effects of

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

Translocation as a tool for the conservation of the jaguar Panthera onca: a case study in the Brazilian Atlantic Forest

Oryx
The success of translocation as a management tool is based on reversing the factors that led to a population becoming threatened or locally extinct. We assessed whether translocating a jaguar Panthera onca into the surroundings of a protected area in the

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Integrated Single‐Cell and TCR Profiling Reveals Protection‐Associated CD8+ T Cell Subsets Linked to Viral Control in PRRSV

Advanced Science, EarlyView.
PRRSV vaccine‐mediated protection is associated with clonally expanded cytotoxic CD8+ T cell subsets driven by viral structural proteins and supported by innate TLR4/TLR8 signaling and CD4+ T cell help, whereas non‐protective responses are characterized by dysfunctional exhausted‐like CD8+ T cells linked to poor viral control.

Social media data from two iconic Neotropical big cats: can this translate to action?

Frontiers in Conservation Science, 2023
IntroductionThere has been a gradual increase in studies of social media data usage in biodiversity conservation. Social media data is an underused source of information with the potential to maximize the outcomes of established conservation measures. In
