The PteridoPortal: A publicly accessible collection of over three million records of extant and extinct pteridophytes

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Pteridophytes—vascular land plants that disperse by spores—are a powerful system for studying plant evolution, particularly with respect to the impact of abiotic factors on evolutionary trajectories through deep time. However, our ability to use pteridophytes to investigate such questions—or to capitalize on the ecological and ...

Disentangling direct and indirect effects of landscape structure on urban bird richness and functional diversity

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract As fragmented landscapes become increasingly common around the world, managing the spatial arrangement of landscape elements (i.e., landscape configuration) may help to promote the conservation of biodiversity. However, the relative effects of landscape configuration on different dimensions of biodiversity across species assemblages are ...

Mechanically Strong Active‐Site‐Enriched Polymer Composite Solid Electrolytes toward Superior Room‐Temperature Performance in Lithium Batteries

open access: yesAdvanced Physics Research, EarlyView.
Blow‐spun MXene doped polyacrylonitrile (PAN) fiber films provide good mechanical strength and more Li+ active sites for low‐crystallinity solid polymer electrolytes, achieving a specific capacity of 134.8 mAh g−1 for the LFP. Abstract Solid‐state electrolytes (SSEs) are promising for lithium batteries with higher safety, cycling stability, and energy ...

How opposing ideological groups use online interactions to justify and mobilise collective action

open access: yesEuropean Journal of Social Psychology, Volume 52, Issue 7, Page 1082-1110, December 2022., 2022
Abstract The purpose of this pre‐registered study was to investigate how different ideological groups justified and mobilised collective action online. We collected 6878 posts from the social media accounts of pro‐Black Lives Matter (n = 13) and anti‐Black Lives Matter (n = 9) groups who promoted collective action in the month after George Floyd's ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...
