In natural biological communities the disappearance of one species can have knock-on effects causing extinction of further species from the food web. To investigate these effects we used an evolutionary model to assemble many independent simulated food webs, and studied their dynamical behaviour when one species was deleted. On average, only 2.1% of the remaining species went extinct as a result of the deletion. However, the probability of extinction of predators and indirect predators (more… 
Loss of predator species, not intermediate consumers, triggers rapid and dramatic extinction cascades
TLDR
It is shown that loss of single predator species in isolation can, irrespective of their identity or the presence of other predators, trigger rapid secondary extinction cascades in natural communities far exceeding those generally predicted by theory.
Trophically Unique Species Are Vulnerable to Cascading Extinction
TLDR
Analysis of natural and model food webs show that secondary extinctions cause loss of trophic diversity greater than that expected from chance, a result that is robust to variation in food web structure, distribution of interactions strengths, functional response, and adaptive foraging.
Metacommunity stability and persistence for predation turnoff in selective patches
TLDR
This study presents how a predation turnoff in selective patches affects the stability and persistence of a metacommunity and identifies the network configurations that exhibit a unique number of clusters.

TLDR
Comparison of a food web that includes parasites showed significant effects of invasion on the native community as well as a hypothetical invasion that significantly reduced the connectance of the web because the loss of 17 native trematode species eliminated many links.
Species' traits and food‐web complexity interactively affect a food web's response to press disturbance
TLDR
This study investigates the effect of specieslevel press disturbances in a large set of model food webs and indicates that both the traits of disturbed species and the complexity of the food web need to be considered in attempts to predict or manage the ecological impact of press disturbances.

TLDR
An individual-based predator-prey model of biological coevolution, using linear stability analysis and large-scale kinetic Monte Carlo simulations, generates a sequence of quasisteady communities in the form of simple food webs that are quite resilient toward the loss of one or a few species.

Food web structure and the evolution of ecological communities
TLDR
Results obtained are summarized on the macro-evolutionary dynamics of speciations and extinctions, and on the statistical properties of the food webs that are generated by the model.
The influence of predator--prey population dynamics on the long-term evolution of food web structure.
TLDR
Although there are significant fluctuations in species diversity because of speciation and extinction, very large-scale extinction avalanches appear to be absent from the dynamics, and no evidence for self-organized criticality is found.
Food web design and the effect of species deletion
TLDR
Two conclusions are drawn: real systems do not recover, at least quickly, from large perturbations and so requiring model systems to have this feature unlikely to be informative about food web design, and donor-control dynamics do not describe many real systems and, with their rejection goes one of the otherwise more plausible model systems where stability increases with complexity.
Modelling Coevolution in Multispecies Communities.
TLDR
The Webworld model is introduced, which links together the ecological modelling of food web structure with the evolutionary modelling of speciation and extinction events, and the theory of self-organized criticality is discussed.
The Role of Indirect Effects in Food Webs
TLDR
Under this scenario where affects are attenuated by distance in the food web, it would expect either prey or predators of the focal species to be most affected by a change in the rate of harvest of the focus species.
Species positions and extinction dynamics in simple food webs.
TLDR
A well-defined set of small model food webs is analysed and it is found that homogeneity in the connectedness structure increases the probability of extinction events and in addition to the number of interactions, their orientations also influence the future of species in a web.
Species loss leads to community closure
TLDR
Cascading extinctions have previously been recorded, but it is shown that the relative magnitude of the cascade is dependent on community size (and not only trophic structure) and that the reintroduction of the original species lost often is impossible.
Network structure and biodiversity loss in food webs: robustness increases with connectance
TLDR
Food-web structure mediates dramatic effects of biodiversity loss including secondary and ‘cascading’ extinctions and robustness increases with food-web connectance but appears independent of species richness and omnivory.
Topological structure and interaction strengths in model food webs
Regional Species Pools and the Assembly of Local Ecological Communities
TLDR
The results show that communities built from species-rich pools develop more slowly to invasion-resistant states, and that saturation of local communities such that the number of species present locally becomes uncoupled from the richness of the pool.
