Can we predict microhabitat selection of animals using drones? We did in our new article from @wildlifebiology.bsky.social and found that traditional and 3D metrics (derived from drones) do an good job at explaining and predicting microhabitats. nsojournals.onlinelibrary.wiley.com/doi/10.1002/...
Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine-scale r....

Scientists have been publishing climate models since ~1970.
A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.
It turns out most models were pretty spot-on:
