Ecological Networks Across Environmental Gradients
TLDR
Taking spatial and temporal processes into account can further elucidate network variation and improve predictions of network responses to environmental change.Abstract:
Ecological networks have a long history in ecology, and a recent increase in network analyses across environmental gradients has revealed important changes in their structure, dynamics, and functioning. These changes can be broadly grouped according to three nonexclusive mechanisms: (a) changes in the species composition of the networks (driven by interaction patterns of invaders, nonrandom extinction of species according to their traits, or differences among species in population responses across gradients); (b) changes that alter interaction frequencies via changes in search efficiency (driven by altered habitat structure or metabolic rates) or changes in spatial and temporal overlap; and (c) changes to coevolutionary processes and patterns. Taking spatial and temporal processes into account can further elucidate network variation and improve predictions of network responses to environmental change. Emerging evidence links network structure to ecosystem functioning; however, scaling up to metanetworks o...read more

TL;DR: An overview of tools that can be used to describe and compare the functional and dynamic roles of species based on their position in the network and the organization of their interactions as well as associated new methods to test the significance of these results are described.

Wheat rhizosphere harbors a less complex and more stable microbial co-occurrence pattern than bulk soil
TL;DR: It is shown that distinct microbial co-occurrence patterns exist in wheat rhizosphere, which could be associated with variable agricultural ecosystem properties, and Keystone species that played essential roles in network structure were predicted to maintain a flexible generalist metabolism and had fewer significant correlations with environmental variables.

TL;DR: This review of studies investigating variation in network structures along environmental gradients highlights how methodological decisions about standardization can influence their conclusions, and warns against a comparison of studies that rely on distinct forms of standardization.

TL;DR: It is argued that generalists’ responses present a powerful and underutilized approach to understanding and predicting the consequences of climate change and may serve as much-needed early warning signals for monitoring the looming impacts of global climate change on entire ecosystems.

TL;DR: A satisfactory resolution of the underlying factors determining network structure will require substantial additional information, not only on independently assessed abundances, but also on traits, and ideally on fitness cons...

Global change and species interactions in terrestrial ecosystems.
TL;DR: It is concluded that in order to reliably predict the effects of GEC on community and ecosystem processes, the greatest single challenge will be to determine how biotic and abiotic context alters the direction and magnitude of G EC effects on biotic interactions.

The nested assembly of plant-animal mutualistic networks
TL;DR: It is shown that mutualistic networks are highly nested; that is, the more specialist species interact only with proper subsets of those species interacting with the more generalists, which generates highly asymmetrical interactions and organizes the community cohesively around a central core of interactions.

Network structure and biodiversity loss in food webs: robustness increases with connectance
TL;DR: 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.

Stability of Ecological Communities and the Architecture of Mutualistic and Trophic Networks
TL;DR: It is concluded that strong variations in the stability of architectural patterns constrain ecological networks toward different architectures, depending on the type of interaction.
