The nested assembly of plant–animal mutualistic networks
TLDR
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.
Early-warning signals for critical transitions
TLDR
Work in different scientific fields is now suggesting the existence of generic early-warning signals that may indicate for a wide class of systems if a critical threshold is approaching.
The modularity of pollination networks
TLDR
If these key species go extinct, modules and networks may break apart and initiate cascades of extinction, Thus, species serving as hubs and connectors should receive high conservation priorities.
Global change and species interactions in terrestrial ecosystems.
TLDR
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.
Plant-Animal Mutualistic Networks: The Architecture of Biodiversity
TLDR
The mutually beneficial interactions between plants and their animal pollinators and seed dispersers have been paramount in the generation of Earth's biodiversity and understanding how coevolution proceeds in these highly diversified mutualisms among free-living species presents a conceptual challenge.
The architecture of mutualistic networks minimizes competition and increases biodiversity
TLDR
It is shown that nestedness reduces effective interspecific competition and enhances the number of coexisting species, and that a nested network will naturally emerge if new species are more likely to enter the community where they have minimal competitive load.
Invariant properties in coevolutionary networks of plant-animal interactions
TLDR
This work hypothesizes that plant–animal mutualistic networks follow a build-up process similar to complex abiotic nets, based on the preferential attachment of species, and reveals generalized topological patterns characteristic of self-organized complex systems.
Asymmetric Coevolutionary Networks Facilitate Biodiversity Maintenance
TLDR
By using a simple dynamical model, it is shown that asymmetries inherent in coevolutionary networks may enhance long-term coexistence and facilitate biodiversity maintenance.
Approaching a state shift in Earth’s biosphere
TLDR
Evidence that the global ecosystem as a whole is approaching a planetary-scale critical transition as a result of human influence is reviewed, highlighting the need to improve biological forecasting by detecting early warning signs of critical transitions.
Anticipating Critical Transitions
TLDR
How previously isolated lines of work can be connected are reviewed, it is concluded that many critical transitions (such as escape from the poverty trap) can have positive outcomes, and how the new approaches to sensing fragility can help to detect both risks and opportunities for desired change.
