Camera traps as sensor networks for space-time exploration of terrestrial mammal communities
Published 2019“…Using kernel density functions with descriptive and multivariate statistics, this chapter showed that most mammal species responded to the ecological variability brought about by seasonality by adjusting their diel activity rhythms between winter and summer, resulting in a reduction of time exposure to a physiologically stressful environment caused by high temperatures in summer. …”

Assessing the value of ecological intensification in improving smallholder farmers' food security and rural livelihoods in a changing climate
Published 2023“…More specifically, the results show that the integration of agroecological approaches in smallholder cropping systems has the potential to deliver ecological intensification in which productivity is improved and ecosystem services such as climate change regulation through reduction of GHG emissions from cropping systems are simultaneously increased to enhance environmental sustainability. …”
