Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

Climate‐Resilient Agri‐Food Systems (CRAFS): A Review of Approaches and Outcomes of Agri‐Food Systems

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change is increasingly destabilizing agri‐food systems globally, with complex disruptions extending across production, distribution, and consumption. In response, climate‐resilient agri‐food system (CRAFS) approaches have gained prominence as a means to sustain food security under escalating climatic stressors.

Apropriate Agronomic Practices for Pest and Disease Management

open access: yesInternational Journal of Bio-Resource and Stress Management, 2017
Pesticides play important role in agricultural production by means of increasing crop yield and farmer’s income. The indiscriminate use of chemicals has resulted in a reduction of biodiversity of natural enemies, outbreak of secondary pests, development

Drone-Based Optical Measurements of Heterogeneous Surface Velocity Fields around Fish Passages at Hydropower Dams

open access: yesRemote Sensing, 2020
In Austria, more than a half of all electricity is produced with the help of hydropower plants. To reduce their ecological impact, dams are being equipped with fish passages that support connectivity of habitats of riverine fish species, contributing to ...

Is land‐use deregulation enough to deliver housing?: The case of institutional frictions in India

open access: yesReal Estate Economics, EarlyView.
Abstract This paper examines whether land use deregulation increases housing supply in the presence of additional institutional frictions, such as ill‐defined property rights. India's urban land ceiling (ULC) laws, which put limits on individual ownership of private vacant land in the largest cities, were repealed during the 2000s.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.
