Looking beyond wildlife: using remote cameras to evaluate accuracy of gridded snow data The objective of this study was to use a novel camera trap method to evaluate the accuracy of gridded snow data. We were interested in assessing (1) how snow depth observations from remote cameras co...

The #AI model used data from a variety of camera setups, including the SiMPL magnet (to be published shortly) and snow stake design zslpublications.onlinelibrary.wiley.com/doi/full/10..... The classification approach had very high accuracy for species in New England and beyond! Please try it out!

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/...

New paper! If trees are closely related, does it matter where they are from to plant-eating insects? We raised >950 Promethea moth caterpillars on 14 Prunus species to answer that question. Turns out, it matters a lot! Non-native trees = Lower performance

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:
