More pumas (Puma concolor) does not change perceptions: The mismatched response of ranchers to the presence of a top carnivore

People and Nature, EarlyView.
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores are frequently at the centre of these conflicts because of the perceived and real threats they pose to livestock and human safety.

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

People and Nature, EarlyView.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Knee height is often right: evaluating device height effects on camera trapping rate

Remote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Kinetics of nopyl acetate synthesis by homogeneously catalyzed esterification of acetic acid with nopol

Revista Facultad de Ingeniería Universidad de Antioquia, 2018
Se estudió la esterificación de nopol con ácido acético para producir acetato de nopilo utilizando ácido sulfúrico como catalizador homogéneo. Los experimentos se llevaron a cabo en un reactor por lotes variando la temperatura (50, 60, 70 y 80 °C), la ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
