Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

Integrated Learning‐Based Ageing Assessment of Silicone Rubber

open access: yesHigh Voltage, EarlyView.
ABSTRACT The surface ageing of silicone rubber composite insulators, widely used in power systems, poses significant challenges. This study integrates Fourier transform infrared (FTIR) spectroscopy with machine learning to evaluate ageing states and explore underlying mechanisms under various environmental conditions.

Environmental Total Factor Productivity and the Cost‐Effectiveness of GHG Emission Reduction: The Case of Crop Production in China

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT China's diversified agricultural policies have effectively improved both the yield and environmental performance of the crop sector. Quantifying productivity trends and their drivers is key to formulating strategies for high‐quality and low‐carbon crop development.

Host Exploitation by Cuckoos in China: A Review and Real‐Time Tracking Program for Parasitism Records

open access: yesIntegrative Zoology, EarlyView.
China is a global hotspot for cuckoo‐host diversity, with 17 cuckoo species, exploiting 142 host species. We reveal adaptive matching in body size and egg traits, along with niche partitioning among cuckoos, while identifying eight new host species.

Resource Availability and Habitat Quality Drive Time‐Lag Effects in High‐Altitude Ungulate Distribution

open access: yesIntegrative Zoology, EarlyView.
Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...
