The Emerging Role of UAV for Heathland Monitoring and Conservation: State of the Art and Perspectives

Remote Sensing in Ecology and Conservation, EarlyView.
Heathland ecosystems are currently in a degraded state due to agricultural transformations and the effects of climate change. They are semi‐natural ecosystems hosting a variety of species (fauna and flora), and they also carry landscape and cultural importance, hence the need to pay careful attention to their conservation.

Seeing both the forest and the trees: An automated workflow for ultra‐high‐resolution drone imaging of tropical canopies

Methods in Ecology and Evolution, EarlyView.
Abstract Tropical forest canopies host diverse tree and liana assemblages, yet key foliar and reproductive traits needed for taxonomic identification of canopy plants are often difficult to see from the forest floor, creating a bottleneck in inventories.

Climatic factors, landscape composition and host plant traits co‐drive fruit infestation of unmanaged walnut trees by the invasive pest fly Rhagoletis completa (Cresson, 1929) (Diptera: Tephritidae)

Agricultural and Forest Entomology, EarlyView.
The study examined multiscale factors influencing walnut fruit infestations by the invasive pest fly Rhagoletis completa. Infestation rates increased with fruit size, host tree abundance, grasslands, hedgerows and temperatures, but decreased with anthropogenic habitats and heavy spring rainfall.

Spatial variation in cartilage T2 of the knee [PDF]

Journal of Magnetic Resonance Imaging, 2001
AbstractTechnical limitations imposed by resolution and B1 homogeneity have thus far limited quantitative in vivo T2 mapping of cartilage to the patella. The purpose of this study is to develop T2 mapping of the femoral/tibial joint and assess regional variability of cartilage T2 in the knee. Quantitative in vivo T2 mapping of the knee was performed on

Indirect labour market impacts: Spillovers, displacement and policy evaluation

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract This survey reviews approaches to measuring indirect labour market effects of policies and shocks. Fixed‐price multipliers organize gross supply‐chain and expenditure linkages, but do not generally measure net job creation. Regional exposure and quasi‐experimental designs provide credible evidence on local responses, but usually identify ...

Napping during cognitive behavioural therapy for insomnia: Friends or foes?

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Cognitive and Behavioural Therapy for Insomnia (CBT‐I) is the gold standard treatment for chronic insomnia, with one crucial step being the restriction of time spent in bed. This restriction often intensifies early afternoon sleepiness, leading to a natural gateway for a short recuperative nap, which might foster adherence to CBT‐I over time ...

Proprioception drives tension wood formation for autotropic straightening and postural control in trees

New Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...
