Grazing alters ecosystem multifunctionality via changes in taxonomic diversity and functional identity in temperate grassland, China

open access: yesGlobal Ecology and Conservation, 2023
Livestock grazing is the major land-use regime of grasslands, and affects ecosystem structure and functioning considerably. However, few studies have examined how grazing intensity impacts ecosystem multifunctionality (EMF) via biodiversity loss.

Sorption of tetrabromobisphenol A onto microplastics: Behavior, mechanisms, and the effects of sorbent and environmental factors

open access: yesEcotoxicology and Environmental Safety, 2021
Microplastics (MPs) and halogenated organic pollutants coexist in ambient water and MPs tend to sorb organic pollutants from surrounding environments.

O3–precursor relationship over multiple patterns of timescale: a case study in Zibo, Shandong Province, China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
In this study, we developed an approach that integrated multiple patterns of timescale for box modeling (MCMv3.3.1) to better understand the O3–precursor relationship at multiple sites and through continuous observations.

Terrestrial ecosystem health under long-term metal inputs: modeling and risk assessment [PDF]

open access: yes, 2016
Metal contamination of soils may pose long-term risks to ecosystem health if not properly managed. Future projection of contamination trends, coupled with ecological assessment, is needed to assess such risks.

Disrupting effects of neonicotinoids and their interaction with metals on thyroid hormone, an evidence of children in a rural area, South China

open access: yesEcotoxicology and Environmental Safety
Neonicotinoids exposure was found to induce thyroid dysfunction. However, there lack of direct evidence between neonicotinoids exposure and thyroid hormone (TH) disruption in population study, especially in children, which limits the understanding on ...

Toward refined environmental scenarios for ecological risk assessment of down-the-drain chemicals in freshwater environments [PDF]

open access: yes, 2016
Current regulatory practice for chemical risk assessment suffers from the lack of realism in conventional frameworks. Despite significant advances in exposure and ecological effect modeling, the implementation of novel approaches as high-tier options for

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
