Food Chains and Food Webs in Aquatic Ecosystems
Applied Sciences, 2020 Food chains and food webs describe the structure of communities and their energy flows, and they present interactions between species. Recently, diverse methods have been developed for both experimental studies and theoretical/computational studies on ...

Foundation species enhance food web complexity through non-trophic facilitation. [PDF]
PLoS ONE, 2018 Food webs are an integral part of every ecosystem on the planet, yet understanding the mechanisms shaping these complex networks remains a major challenge.

On the interplay of speciation and dispersal: An evolutionary food web model in space [PDF]
, 2014 We introduce an evolutionary metacommunity of multitrophic food webs on several habitats coupled by migration. In contrast to previous studies that focus either on evolutionary or on spatial aspects, we include both and investigate the interplay between ...

Ecology: Engineered food webs [PDF]
Current Biology, 1996 An important new study shows that, in a food web, the strengths and arrangement of the interactions between species are determining factors of stability of the system.

Food Webs: Experts Consuming Families of Experts
, 2005 The question what determines the structure of natural food webs has been listed among the nine most important unanswered questions in ecology. It arises naturally from many problems related to ecosystem stability and resilience.

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.

Molecular Oncology, EarlyView.PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Commonality in structure among food web networks [PDF]
Network Biology, 2015 A goal of this study was to determine similarities in structure among food webs that are otherwise disparate with regard to species, population, and size.

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.
