Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem
Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Microtargeting for conservation
Conservation Biology, Volume 33, Issue 5, Page 1141-1150, October 2019., 2019 Abstract Widespread human action and behavior change is needed to achieve many conservation goals. Doing so at the requisite scale and pace will require the efficient delivery of outreach campaigns. Conservation gains will be greatest when efforts are directed toward places of high conservation value (or need) and tailored to critical actors.

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.
