Environmental DNA, Volume 5, Issue 6, Page 1516-1526, November 2023., 2023 Study to determine if rare taxa can be detected using molecular methods in hive pollen collected from a nearby apiary. Honey bees were confirmed to visit the target taxa when abundant but were not detected in the hive pollen while they were rare. Abstract The detection of rare taxa, crucial to conservation and biosecurity, presents many challenges that

Ecological Monographs, Volume 93, Issue 3, August 2023., 2023 Abstract Alternative states defined by tree‐canopy dominance result in different ecosystem functioning and shape habitat conditions for the understory vegetation. One example in the boreal forest is the alternation between broadleaf deciduous and coniferous forests. Disturbances related to natural fires and human land uses have produced changes in tree‐

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 ...
