Maternal health remains a critical global concern, particularly in underserved populations and in low‐ and middle‐income countries where access to safe and effective therapeutics is limited. Despite the use of medications by most women during pregnancy, the exclusion of pregnant and lactating women from clinical trials has resulted in significant data ...

Site-level quantification of Net Ecosystem Production (NEP) and associated components rely on eddy covariance and biometric methods. Here these techniques are compared for global forest carbon fluxes, revealing differences in NEP, but similar estimates ...

Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

A Terrestrial Ecosystem Carbon Sink Assessment Model Considering Forest Age Dynamics (CEVSA‐AgeD)
The large variation in net ecosystem productivity (NEP) with forest age was dominated by the dynamics of net primary productivity (NPP)–which in turn was determined by the different response slopes of gross primary productivity (GPP) and autotrophic ...

Mass Energy and Flow in closed ecosystems [PDF]
The general equations of biomass and energy transfer for an n-species, closed ecosystem are written. It is demonstrated how in "ecological time" the parameters describing the dynamics of biomass transfer are related to the parameters of energy transfer ...

Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts
Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...

A novel organic–inorganic YSZ@PANI/SnS2 composite nanofiber film was prepared via an in‐situ construction strategy of a PANI interfacial layer. The biomimetic "branch‐leaf" structure effectively disperses and releases stress and energy, while accelerating gas diffusion/transport and providing abundant active sites.

Cultivated Grassland Types Differently Affected Carbon Flux Downstream of the Yellow River
Cultivated grasslands are an important part of grassland ecosystems and have been proven to be major carbon sinks, then playing an important role in the global carbon balance.

A multi‐level approach for multi‐objective optimization in process eco‐design
Abstract This work addresses a central challenge in process eco‐design: how to efficiently integrate environmental and economic criteria—often conflicting—into early design stages while managing the high dimensionality of Life Cycle Assessment (LCA) indicators.
