Hierarchicalization of chaotic food webs using Interpretive Structural Modeling [PDF]

Network Biology, 2013
Ecologists always meet complex food webs without clear hierarchical structure. At certain degree it will retard further analysis of food webs. In present study we transferred chaotic food webs into hierarchicalized food webs using Interpretive Structural

The architecture of predator-prey and the relationship between complexity and stability [PDF]

, 2010
Theoretical studies predict that the stability of an ecosystem is negatively correlated with its complexity, measured by the number of interacting species. On the other hand, empirical evidence indicates that food webs are highly interconnected.

You can't go home again: Changes in trophic niche following extinction and recolonization of the New Zealand sea lion

Ecosphere
Recolonization or range expansion of large marine predators can be facilitated by reestablishing formally important trophic linkages within intact coastal marine food webs.

Essential Biomolecules in Food Webs

Frontiers in Ecology and Evolution, 2019
We here review the ecological role of essential nutritional biomolecules [fatty acids (FA), amino acids (AA), sterols, vitamins] in aquatic and terrestrial food webs, encompassing the forces behind their environmental distribution.

Comment: Food web interactions and biomanipulation in Australian reservoirs [PDF]

, 1997
The authors have been studying the control of phytoplankton biomass in several Australian reservoirs. To manipulate fish communities in order to reduce phytoplankton biomass, one needs a thorough understanding of processes in the plankton-associated food

Acoustic Assessment of the Micronekton Community on the Chatham Rise, New Zealand, Using a Semi-Automated Approach

Frontiers in Marine Science, 2019
Micronekton are a key component of the pelagic food web of the Chatham Rise east of New Zealand. The Chatham Rise is an important fishing area for hoki (Macruronus novaezelandiae), New Zealand’s largest finfish fishery, and a predator on mesopelagic fish.

Are type 3 functional responses just statistical apparitions?

Ecosphere
Type 3 (sigmoidal) functional responses can protect rare prey from predation, but such functional responses are not often described. It is also not clear that factors that are hypothesized to promote type 3 functional responses, such as predator–prey ...

An illustration of web survey methododlogy [PDF]

, 2009
A former study in the Danish primary schools has shown that there is an association between organic school food policies and indicators (proxies) for healthy eating among children when (school food coordinators) statements on indicators (proxies) for ...

Organic school food policies are supportive for healthier eating behaviours – results from an observational study in Danish schools [PDF]

, 2010
Purpose – The purpose of this study was to examine whether organic food intervention strategies in Danish school meal systems can support the development of healthier eating patterns among pupils.
