Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Functional group and aridity regulate impacts of climate change on plant phenology: a meta-analysis

open access: yesNature Communications
The interaction between temperature and precipitation greatly affects plant phenology. However, these effects can vary between additive, antagonistic, and synergistic, and it is not clear what determines these different outcomes.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

open access: yesIntegrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

The Neuroprotective Effects of Cyanidin Derivatives on AlCl3-Induced Zebrafish Model of Alzheimer’s Disease

open access: yesMolecules
Alzheimer’s disease (AD) is characterized by cholinergic deficits and neuronal damage, making acetylcholinesterase (AChE) a crucial therapeutic target. Cyanidin derivatives, sourced from the diet as anthocyanins, exhibit neuroprotective properties, yet ...

Mitigating Human–Large Carnivore Conflicts via Time‐Regulated Management of Free‐Ranging Livestock in the Sanjiangyuan Region, China

open access: yesIntegrative Zoology, EarlyView.
The graphical abstract illustrates the comprehensive workflow of our study, from the deployment of infrared cameras at sites with high activity of four large carnivores, through data collection and assessment of activity patterns, to the prediction of time periods with potential human–large carnivore conflicts and the proposal of corresponding ...

Downregulation of EPAS1 and EGLN1 mRNA Expression Associated With High‐Altitude Adaptive Genetic Variants in Sherpa Highlanders

open access: yesAnnals of Human Genetics, EarlyView.
ABSTRACT Background and Aims Sherpa highlanders exhibit remarkable tolerance to hypoxia, most likely due to genetic adaptations shaped by natural selection at high altitude. This study examined the roles of endothelial PAS domain protein 1 (EPAS1) and egl‐9 family hypoxia‐inducible factor 1 (EGLN1) in the genetic mechanisms underlying this adaptation ...

The Significant Impact of Lost Species' Identity, Number and Abundance on Functional Structure of Alpine Meadow

open access: yesEcology and Evolution
Biodiversity, the cornerstone of ecosystem functions and services, faces threats from anthropogenic climate change. However, it remains unclear how species loss, including abundance, number, and identity of lost species, would alter the functional ...

The nation‐state, non‐Western empires, and the politics of cultural difference

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract While empires have been central to political theory, they almost always refer to Western forms of imperialism and colonialism to which non‐Western societies are subject. But precolonial empires have ruled much of the world for much of known history. Building on recent International Relations (IR) scholarship, this article reconstructs an ideal

The Unbecoming Ghost: Spectropolitics in the Making and Unmaking of BHU's Bhoot Vidya Ayurveda Certificate Program

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT This essay examines the controversy surrounding the Bhoot Vidya certificate program proposed by the Faculty of Ayurveda at Banaras Hindu University in 2019. Drawing on media coverage, curricular materials, and government policy, I analyze how the debate reveals broader tensions in the politics of contemporary Ayurveda, nationalism, and ...
