Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Betaine‐, xylitol‐, and extra virgin olive oil–based toothpaste modulates inflammation and oral nitric oxide pathway: Clinical trial in gingivitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Gingivitis is a prevalent and reversible inflammatory condition driven by microbial dysbiosis. Beyond plaque control, interest has grown in oral hygiene formulations capable of modulating inflammation while preserving key microbial functions. Extra virgin olive oil (EVOO), together with xylitol and betaine, has demonstrated clinical

Invisible barriers and lasting scars for racially/ethnically minoritized youth: The role of state‐level opportunity on adverse childhood experiences exposure risk

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Previous research has shown there are racial/ethnic disparities in exposure to adverse childhood experiences (ACEs) that can affect youths’ physical and mental well‐being. Structural opportunity factors—including a lack of economic, community, educational, and health resources—may increase exposure to ACEs among youth of color relative to non ...

Life history stability under climate change: a wildflower at the northern edge of its range

open access: yesNordic Journal of Botany, EarlyView.
Stabilities of life history traits for a widespread native perennial wildflower, Rudbeckia laciniata L., are described for five populations near the northern edge of its range in North America. Theory proposes that such populations experience variable levels of stress as suitable abiotic conditions shift north or south from year to year, which ...

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape
