Personalized multimodal physiological modeling of menstrual cycle dynamics using endocrine, metabolic and wearable signals

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract Menstrual cycle tracking remains challenged by the limited physiological scope and inconsistent generalizability of existing wearable‐based approaches, which often rely on individual sensing modalities that incompletely capture the complexity of menstrual physiology.

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Electron probe microanalysis of extremely fine‐grained tephras: new protocols and insights for analyses at the 1 μ ${\rm{\mu }}$m scale

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

Use of natural ensiling additives with tropical grasses: Physicochemical properties, in vitro fermentation characteristics, and microbial community diversity indices

open access: yesJSFA reports, EarlyView.
Abstract Background Improving feed quality, availability, and cost‐effectiveness is a big challenge for livestock to ensure animal‐derived food for nutritional security. The aim of the study was to find out how some natural ensiling additives affect physicochemical properties, proximate composition, microbial population, in vitro fermentation ...

Landscape drivers of scaled quail occurrence across a broad spatiotemporal scale: implications for habitat management

open access: yesThe Journal of Wildlife Management, EarlyView.
Combining large‐scale avian surveys with remote sensing products revealed landscape variables that likely limit scaled quail occurrence at the ecoregion scale in Texas. Promoting management practices that address ecoregion‐specific limiting factors may be key to averting further declines.

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Mechanism of Combined Improvement of Saline‐Alkali Soil by Artificial Humic Acid and Microbial Inoculant

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT To address the widespread constraints imposed by saline‐alkaline soils on agricultural production worldwide, the combined reclamation and carbon cycle regulation effects of artificial humic acid (AHA) and a multifunctional microbial inoculant were evaluated through pot experiments. Results demonstrated that co‐application of AHA (4 g·kg−1) and
