Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Comprehensive tree assessments for prioritising conservation action in Mesoamerica

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Tree species are of ecological and social importance globally. Mesoamerica has a diverse tree flora, and the region has experienced major changes in natural habitats due to human activities. In this study, for the first time, we assessed the conservation status of the region's tree species and found that 46% of trees in the region are at risk of ...

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

Graphene‐Based Opto‐Electronic Platform for Ultra‐Sensitive Biomarker Detection at Zeptomolar Concentrations

open access: yesSmall Methods, EarlyView.
An opto‐electronic graphene‐based biosensor detects immunoglobulin M (IgM) at 100 zeptomolar (10−19 M) concentration. It features a biofunctionalized gold electrode capacitively coupled to a graphene electrode via a water‐soaked paper strip. Surface potential changes induced by few affinity events are transduced as shifts of the graphene phonon ...
