Social Determinants of Sepsis Mortality in the United States: A Retrospective, Epidemiologic Analysis

open access: yesWorld Medical &Health Policy, Volume 17, Issue 4, Page 823-830, December 2025.
ABSTRACT Sepsis is a leading cause of mortality in the United States, with over 350,000 deaths annually, yet the contribution of neighborhood‐level social determinants of health (SDoH) remains underexplored. We conducted a retrospective analysis of 4.4 million hospitalized patients with sepsis, identified using ICD‐10 codes, leveraging de‐identified ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Geographic variation in developmental plasticity among populations of the canyon treefrog in response to temperature and pond‐drying

open access: yesJournal of Zoology, Volume 324, Issue 2, Page 103-117, October 2024.
This study focuses on the responses of the canyon tree frog (Dryophytes arenicolor) larvae to temperature and pond‐drying. Conducting a common garden experiment with larvae from three distinct populations, we found significant geographic variation in plastic responses and observed that populations exhibit specific responses to each treatment in both ...

Range‐wide intraspecific variation reflects past adaptation to climate in a gypsophile Mediterranean shrub

open access: yesJournal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.
Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...
