Environmental Gradients in Lizard Colouration. [PDF]

Ecol Evol
In our study, we examined how environmental gradients influence dorsal colour variation in Lusitanian wall lizards across their range in the Iberian Peninsula. We found that lizard dorsal lightness is primarily associated with humidity, supporting Gloger's hypothesis, while body size influences dorsal lightness indirectly through Bergmann's hypothesis,

CEO‐employee pay ratio disclosure and dividend policy

Journal of Financial Research, EarlyView.
Abstract We examine whether and how the magnitude of the CEO pay ratio affects dividend policy in the context of inequality‐averse investors. Our results demonstrate a positive association between the two and remain robust to endogeneity concerns. We find that the CEO pay ratios positively affect dividends irrespective of whether CEO compensation ...

Population Genetics of an Endemic Species Mongoloniscus sinensis (Isopoda: Oniscidea) and Diversification Dynamics Across Northern China

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We explored the population genetics and demographic history of an isopod species endemic in temperate China on the basis of three mitochondrial genes. Three clusters were identified. The Midland group has the highest genetic diversity, and the greatest differentiation between the East and West groups was due to the geographical barrier caused by the ...

A multidisciplinary study on the location of Roman sites in the southern sub‐plateau of the Iberian Peninsula

Archaeometry, Volume 67, Issue 5, Page 1373-1390, October 2025.
Abstract Architectural and engineering elements of the Roman civilization constitute an important cultural heritage. Nevertheless, not all ancient Roman cities and the roads connecting them have been found, mainly because classical geographical sources show a significant lack of precision.

Line Ratio of Optical Emission Spectroscopy Peaks for Predicting Deposition Rate and Refractive Index of Silicon Nitride in Plasma Enhanced Chemical Vapor Deposition Processes

Plasma Processes and Polymers, Volume 22, Issue 8, August 2025.
Optical emission spectroscopy (OES) was used to predict silicon nitride (SiNx) film properties in plasma enhanced chemical vapor deposition (PECVD), with I N 2 + / I N 2 line ratio strongly correlating with deposition rate and the I SiH / I NH line ratio correlating very closely with refractive index, both showing high accuracy. ABSTRACT In this study,

Counterfactual Uncertainty Quantification of Factual Estimand of Efficacy From Before‐and‐After Treatment Repeated Measures Randomized Controlled Trials

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 18, Issue 4, August 2025.
ABSTRACT This article quantifies the uncertainty reduction achievable for counterfactual estimand, and cautions against potential bias when the estimand uses Digital Twins. Posed by Neyman in 1923 (Statistical Science, 1990;5: 465–472) who showed unbiased point estimation from designed factual experiments is possible, counterfactual uncertainty ...

Prevalence of Salmonella, Cryptosporidium and Leptospira in Invasive Pond Slider (Trachemys scripta) in North‐Western Italy

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
Natural lakes and ponds typically feature green areas where people engage in recreational and sporting activities. In Italy, these areas are often inhabited by non‐native freshwater turtles, even at high densities. However, freshwater turtles have been identified as natural carriers for various pathogens that can be transmitted to humans, making their ...

Underlying Spatial Diversity Patterns of Freshwater Crabs in Southern China, With Recommendations for Conservation of Freshwater Biodiversity

Ecology and Evolution, Volume 15, Issue 6, June 2025.
To the best of our knowledge, this is the first comprehensive study of freshwater crab diversity patterns across the south subtropical‐tropical zone of China in terms of species richness, endemism, and influencing factors, thereby offering a sound basis for the conservation of freshwater biodiversity in China. We highlight the necessity of establishing

Heat Stress Response in Ruditapes Decussatus: Transcriptional Regulation of Key Pathways and Novel SNPs in Antioxidant Genes

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Climate change is known to affect all levels of biology, setting at risk ecological balance. Among other organisms' groups, aquatic inhabitants, and particularly bivalves, are expected to be influenced to a greater extent owing to their inability to move to more mild temperatures.
