Ecology and Evolution, 2021 Almost all organisms grow in size during their lifetime and switch diets, trophic positions, and interacting partners as they grow. Such ontogenetic development introduces life‐history stages and flows of biomass between the stages through growth and ...

Modelling size structured food webs using a modified niche model with two predator traits. [PDF]
PLoS ONE, 2014 The structure of food webs is frequently described using phenomenological stochastic models. A prominent example, the niche model, was found to produce artificial food webs resembling real food webs according to a range of summary statistics.

Geophysical templates modulate the structure of stream food webs dominated by omnivory
Ecosphere, 2021 Food webs show the architecture of trophic relationships, revealing the biodiversity and species interactions in an ecosystem. Understanding which factors modulate the structure of food webs offers us the ability to predict how they will change when ...

Designing (for) Urban Food Webs
Frontiers in Ecology and Evolution, 2021 Interest is growing in designing resilient and ecologically rich urban environments that provide social and ecological benefits. Regenerative and biocentric designs fostering urban ecological habitats including food webs that provide ecosystem services ...

Dispersal Dynamics in Food Webs [PDF]
The American Naturalist, 2015 Studies of food webs suggest that limited nonrandom dispersal can play an important role in structuring food webs. It is not clear, however, whether density-dependent dispersal fits empirical patterns of food webs better than density-independent dispersal.

Dynamics of Simple Food Webs [PDF]
Bulletin of Mathematical Biology, 2015 We consider a simple food web with commensal relationship, where organisms utilize both external resources and resources produced by other organisms. We show that in such a community with no competition, there is at most one possible equilibrium for each fixed set of surviving species, and develop a natural condition that determines which species ...

Persistence increases with diversity and connectance in trophic metacommunities. [PDF]
PLoS ONE, 2011 We are interested in understanding if metacommunity dynamics contribute to the persistence of complex spatial food webs subject to colonization-extinction dynamics.

Frontiers in Ecology and Evolution, 2018 The impacts of biochemicals driving food web processes are under investigation for just the last few decades. In addition, as jellyfish are drawing increasing attentions because of their mass developments and of their potential capacity of driving food ...

Frontiers in Marine Science, 2017 Ecological research in recent decades revealed that species loss has a predominantly negative effect on ecosystem functioning and stability. Most of these studies were based on random species loss scenarios, but extinctions in nature are not random ...
