Scrutinizing the Wallacean shortfall: global gaps in snake occurrence data across space and environment

open access: yesEcography, EarlyView.
Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Comparison of Distance Discrepancies in Georeferenced and Non-Georeferenced Terrestrial LiDAR Models

open access: yesEPiC Series in Built Environment, 2021
The objective of this study is twofold: (a) To investigate the magnitude of errors introduced by a typical georeferencing procedure when it is applied to a relatively large (five acres), non- georeferenced, but still accurate point-cloud model. The modeled area is a commercial site, and its model was generated via static terrestrial LiDAR.

Knowledge sourcing, geopolitics, and FDI: An empirical analysis on the US green and digital sectors

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary This paper examines how foreign direct investment (FDI) shapes firms' sourcing of knowledge in the digital and green domains under rising geopolitical frictions. We assemble a firm–country dyadic panel (2013–2020) linking US patent backward citations to firms' FDI, enriched with bilateral geopolitical distance and host‐country

Biodiversity as a Dominant Force in Shaping Ethnic Music Styles 生物多样性:塑造民族音乐风格的主导力量

open access: yesIntegrative Conservation, EarlyView.
Our findings show that plant, bird, and mammal diversity considerably shape musical features such as vocal range and ornamental sounds, more so than geography or lifestyle. Our study provides the first empirical evidence linking biodiversity to ethnic music styles. Protecting biodiversity, the musical and cultural will be protected.
