Can honey bees be used to detect rare plants? Taking an eDNA approach to find the last plants in a weed eradication program

open access: yesEnvironmental 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

Spatial resolution impacts projected plant responses to climate change on topographically complex islands

open access: yesDiversity and Distributions, Volume 29, Issue 10, Page 1245-1262, October 2023., 2023
Abstract Aim Understanding how grain size affects our ability to characterize species responses to ongoing climate change is of crucial importance in the context of an increasing awareness for the substantial difference that exists between coarse spatial resolution macroclimatic data sets and the microclimate actually experienced by organisms.

Agrarian change through speculation: Rural elites as land brokers for mining in Colombia

open access: yesJournal of Agrarian Change, Volume 23, Issue 4, Page 706-728, October 2023., 2023
Abstract This paper studies the connections between the expansion of mining capital, speculative forms of land grabbing and agrarian transformation. It is argued that in periods of commodity boom, the landowning rural elite benefits from mining through speculative land deals with mining companies.

Drivers of contrasting boreal understory vegetation in coniferous and broadleaf deciduous alternative states

open access: yesEcological 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

open access: yesEcological 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 ...

A Degradable Device for Sustainable Capillary Blood Sampling

open access: yesAdvanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

Conserving climate‐change refugia: Insights from research and practice

open access: yesConservation Science and Practice, Volume 8, Issue 1, January 2026.
Climate‐change refugia conservation is a strategy to reduce the impacts of climate change on natural and cultural resources. Although there are still gaps in implementation, there have been great advances in refugia science in recent years. Addressing obstacles will help increase the implementation and effectiveness of this area of climate adaptation ...

Exploiting algal strains for robust cross‐domain phytoplankton classification via deep learning

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 11, Page 815-833, November 2025.
Abstract Phytoplankton species are essential bioindicators for evaluating the status of freshwater ecosystems in accordance with the EU Water Framework Directive. However, manual identification of phytoplankton is time‐consuming and requires taxonomic expertise. Deep learning (DL) offers promising tools for automating the identification, but challenges

An evidence map and guide for using community science, remote sensing, and environmental DNA for rare plant detection

open access: yesConservation Science and Practice, Volume 7, Issue 10, October 2025.
How can we use novel techniques such as community science, remote sensing, and environmental DNA to detect rare plants? Our evidence map provides information on the types of plants detected with each technique and the habitats in which the studies took place, as well as potential solutions to help overcome problems found with these techniques, sources ...
