Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

Semantic Validation in Structure from Motion [PDF]

, 2023
The Structure from Motion (SfM) challenge in computer vision is the process of recovering the 3D structure of a scene from a series of projective measurements that are calculated from a collection of 2D images, taken from different perspectives.

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

Methods in Ecology and Evolution, EarlyView.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

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.

Vegetation dynamics inside Mediterranean vineyards: A dataset for tracking changes using unmanned aerial vehiclesDataverse

Data in Brief
Service crops are grown to provide ecosystem services in viticulture, but their adoption remains limited due to their competition with grapevine for soil resources.

Selective modulation of NaV channel gating counteracts aberrant hyperexcitability and rescues motor function and survival in a model of spinal muscular atrophy

British Journal of Pharmacology, EarlyView.
Background and Purpose Spinal muscular atrophy (SMA) is a motor neuron disease caused by SMN1 gene loss, leading to reduced survival motor neuron (SMN) protein and progressive motor neuron degeneration. Although SMN‐restoring therapies improve outcomes, residual disease burden and non‐curative efficacy underscore the need for complementary treatments ...

Global Structure-from-Motion Revisited [PDF]

Recovering 3D structure and camera motion from images has been a long-standing focus of computer vision research and is known as Structure-from-Motion (SfM). Solutions to this problem are categorized into incremental and global approaches. Until now, the
