Multi‐Scale Characterization of PLA Composites With Natural‐Based Reinforcements: From Filament to 3D‐Printed Parts

open access: yesPolymer Composites, EarlyView.
Thermal, microstructural, and mechanical characterization of 3D‐printed PLA composite parts. ABSTRACT To address plastic waste and agricultural residue underutilization, this study evaluates the thermal (DSC and FTIR), microstructural (SEM), and mechanical behavior of polylactic acid (PLA) reinforced with flax fibers and olive pit particles, processed ...

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

How digitisation of herbaria reveals the botanical legacy of the First World War

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Digitisation of herbarium collections is bringing greater understanding to bear on the complexity of narratives relating to the First World War and its aftermath – scientific and societal. Plant collecting during the First World War was more widespread than previously understood, contributed to the psychological well‐being of those involved and ...

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

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 ...

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

A comprehensive checklist of Mediterranean wild edible plants: Diversity, traditional uses, and knowledge gaps

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The use of wild edible plants and the traditional knowledge associated with them are rapidly disappearing across the Mediterranean, with serious consequences for biodiversity, cultural heritage, and regional food security. This study compiles and organizes fragmented information to create the first comprehensive catalogue of these plants across the ...

Integrating indigenous crops in agroforestry systems: Lesser yam and teak mixed systems are more profitable than monocultures in Indonesia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low‐ and middle‐income countries and can provide an alternative to introduced staple crops. We showed that lesser yams cultivated together with teak trees (planted at the border of the farm) are more profitable than lesser yam ...
