Host preference and network properties in biotrophic plant-fungal associations

Sergei Põlme, Mohammad Bahram, Hans Jacquemyn, Peter Kennedy, Petr Kohout, Mari Moora, Jane Oja, Maarja Öpik, Lorenzo Pecoraro, Leho Tedersoo
2017 New Phytologist  
Orchid mycorrhizal fungal communities responded most strongly to host identity, but the effect of host was similar among all other fungal guilds.  ...  Instead, network metrics were predominantly affected by sampling and matrix properties, indicating the importance of study design in properly inferring ecological patterns.  ...  We thank three anonymous reviewers and the editor for comments on earlier versions of the paper. O. and P. Kohout performed OTU assignments in arbuscular mycorrhizal datasets.  ...

HIGH INTERVALITY EXPLAINED BY PHYLOGENETIC CONSTRAINTS IN HOST–PARASITE WEBS

David Mouillot, Boris R. Krasnov, Robert Poulin
2008 Ecology  
In addition, we propose a new standardized measure of intervality which describes a novel "facet" of natural networks as it is independent of connectance or web size.  ...  Going one step further, we demonstrate that a null model with phylogenetic constraints on host-parasite links produced webs very similar to empirical ones, particularly when phylogenetic constraints occur  ...  This is publication no. 239 of the Ramon Science Center and no. 588 of the Mitrani Department of Desert Ecology.  ...

Diversity of Interactions: A Metric for Studies of Biodiversity

Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman III, Rebecca F. Hazen
2010 Biotropica  
This metric is different from other indices, such as traditional diversity measures, connectivity and interaction diversity in food-web studies, and the diversity of interaction index in behavioral studies  ...  The lack of a simple interaction metric that is analogous to species richness is one reason why diversity of interactions is not examined as a response or predictor variable in diversity studies.  ...  Almeida Neto, and two anonymous reviewers for comments on the manuscript and to many other ecologists for discussions on these issues.

Coevolution leaves a weak signal on ecological networks

Lauren C. Ponisio, Leithen K. M'Gonigle
2017 Ecosphere  
Our findings indicate that network metrics, on their own, should not be used to make inferences about processes underlying the evolutionary history of communities.  ...  We find that coevolution leaves a weak and variable signal on network topology, particularly nestedness and modularity, which was not strongly affected by the intimacy of interactions.  ...  on the structure of networks.  ...

Networks of online news articles and blog posts are some of the most commonly used data sets in network science.  ...  As a result, they have become a vital piece of network analysis and are used for the evaluation of algorithms that work on large networks, or serve as examples in the analysis of information diffusion  ...  We have provided empirical evidence that, despite it's sparseness, the network is still connected and allows for analyses with regard to the flow of information.  ...
