Inferior plant competitor allocates more biomass to belowground as a result of greater competition for resources in heterogeneous habitats

open access: yesFrontiers in Plant Science, 2023
Nutrient heterogeneity in soil widely exists in nature and can have significant impacts on plant growth, biomass allocation, and competitive interactions.

Allelochemically-based interspecific interactions

open access: yesMathematical and Computer Modelling, 1990
Allelochemicals are chemicals that mediate interactions between different species. Subclasses of allelochemicals are defined and examples of each are given. A simple mathematical model of tannin production in oak leaves is reviewed.

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Spatial scale matters when modeling avian co‐occurrence

open access: yesEcosphere, 2016
The spatial scale at which competition alters the spatial distribution of a species is important to consider when evaluating competitive interactions between species.

The Human Gut Microbiome is Structured to Optimize Molecular Interaction Networks

open access: yesComputational and Structural Biotechnology Journal, 2019
Microbiome studies estimate the functions of bacterial flora in situ on the basis of species composition and gene function; however, estimation of interspecies interaction networks is challenging.

Spatial structural analysis of species associations in mixed Montpellier maple (Acer monspessulanum L.) stands of Zagros woodlands (Case study: Firooz Abad, Fars province) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2018
Interspecific interaction of tree species is an important process in establishing spatial structure of species associations in ecosystems with low species diversity. This study was aimed to investigate the interspecific interactions of Montpellier maple (

Competencia entre mitílidos en el intermareal rocoso de La Lobería, Río Negro, Argentina [PDF]

open access: yes, 2016
Competitive interactions between individuals from a single or different species can regulate population densities and individual growth. Two mussel species, Brachidontes rodriguezii and Perumytilus purpuratus coexist in the rocky intertidal zone of La ...

Time-dependent, species-specific effects of N:P stoichiometry on grassland plant growth [PDF]

open access: yes, 2010
N and P have different eutrophication effects on grassland communities, yet the underlying mechanisms are poorly understood. To examine plant growth in response to the varying (relative) supply of N and P, we conducted a two-year greenhouse experiment ...

Time‐Controlled Refrigerated Stem Cell Therapy Mitigates Scleroderma Fibrosis via Modulation of Mitochondrial Autophagy and Gut Metabolism

open access: yesAdvanced Science, EarlyView.
This study established an RT‐MSCs‐based therapeutic approach for scleroderma in mice. RT‐MSCs attenuated fibrosis by regulating mitochondrial autophagy and restored gut microbiota homeostasis. Metabolomic analyses confirmed recovery of key metabolites, and RT‐MSCs demonstrated favorable lesion targeting and safety profiles.

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

open access: yesAdvanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.
