Scaffold‐Free Living Cellular Structure With Omnidirectional Architectures

Advanced NanoBiomed Research, EarlyView.
Hydrogel lumen confinement enables the direct formation of mechanically stable, scaffold‐free cellular filaments under entirely aqueous, phototoxicity‐free conditions. These processable living building blocks support omnidirectional assembly into complex three‐dimensional architectures, providing a simple and versatile platform for scaffold‐free ...

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

The structure of food webs

Theoretical Population Biology, 1979
Abstract For nonrandom models of species interaction there is a precipitous decrease in stability as connectance increases. However, the range of stability for different models of the same connectance is large; stability also depends on how the species interactions are organized. Systems with species feeding on more than one trophic level (omnivores)

Food Webs

2023
Abstract In the past ten years the ability to leverage modern computational approaches with the increasing quantity of digitized archaeological data has enabled the analysis of archaeologically informed ecological networks. Food webs are a type of ecological network that represent the trophic interactions, or consumption links, within ...

Food Terrorism and Food Defense on the Web

Medical Reference Services Quarterly, 2008
Global food supplies are at risk of both accidental and deliberate contamination. As past incidents have demonstrated, food terrorism may cause social, economic, and political disruption. The United States increased its efforts to protect its food after 9/11 by broadening the roles of existing agencies, including the U.S.

Food and Food Webs

1975
In each water mass a different amount of organic matter and inorganic salts is dissolved; some waters will be well fertilized with plant foods, others more poorly or even barren. There exist desert areas in the oceans as well as on the land. The Sargasso Sea is supposed to be one such desert, and there are others east of Sydney in the Tasman Sea, and ...

Urbanization reshapes a food web

Journal of Animal Ecology, 2019
Abstract Cities represent humanity's most intense impact on our planet, with more than half of all humans now residing in urban areas. Indeed, urbanization has well‐understood impacts on both individual species and general patterns of biodiversity.

Food webs in food webs: the micro–macro interplay of multilayered networks

Trends in Ecology & Evolution
Food webs are typically defined as being macro-organism-based (e.g., plants, mammals, birds) or microbial (e.g., bacteria, fungi, viruses). However, these characterizations have limits. We propose a multilayered food web conceptual model where microbial food webs are nested within food webs composed of macro-organisms.
