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

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
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.

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
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
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
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
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

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 ...
