Advanced Healthcare Materials, EarlyView.Granular hydrogels are emerging microporous platforms for cell culture and delivery, showing great potential for replicating the complex, heterogeneous environments found in natural tissues. This review outlines the design principles of granular hydrogels, highlighting critical factors that determine the final physicochemical properties of the entire ...

Campylobacter in the Food Chain
Advances in Food and Nutrition Research, 2018Currently Campylobacter is the most commonly reported zoonosis in developed and developing countries. In the European Union, the number of reported confirmed cases of human campylobacteriosis was 246,307 in 2016, which represents 66.3 cases per 100,000 population. The genus Campylobacter includes 31 species with 10 subspecies.

There are three hypothesized controls on food‐chain length (FCL): energy supply (or “resource availability”), ecosystem size and disturbance (or “environmental variation”). In this article, the evidence for controls on FCL in freshwater ecosystems is evaluated. First, the various ways FCL can be measured are defined.

On the stability of food chains
Journal of Theoretical Biology, 1975Abstract A mathematical model for an n-species food chain in which the growth and predation functions are not specified is presented and analysed. The stability of such systems under arbitrarily great enrichment is considered, and it is concluded that if growth is limited by nutrient saturation a stable system is in danger of destabilization, but ...

In this chapter we meet a group of people for the first time and with whom the rest of the ethnography will engage. We get a sense of movement in and beyond the estate, of people walking and talking and sharing stories about their lives past and present.

Microbial food chains and food webs
Journal of Theoretical Biology, 1973Abstract Mathematical models for simple microbial food chains and food webs in continuous culture are developed and analyzed. A model for competition of two microbial species for a single scarce resource is also presented as a degenerate case of the food web model. Two models for food chains are developed.

Stoichiometry and food-chain dynamics
Theoretical Population Biology, 2004Traditional models of chemostat systems looking at interactions between predator, prey and nutrients have used only a single currency, such as energy or nitrogen. In reality, growth of autotrophs and heterotrophs may be limited by various elements, e.g. carbon, nitrogen, phosphorous or iron.
