Nested species interactions promote feasibility over stability during the assembly of a pollinator community

Saavedra, Serguei ; Rohr, Rudolf P. ; Olesen, Jens M. ; Bascompte, Jordi

In: Ecology and Evolution, 2016, p. -

The foundational concepts behind the persistence of ecological communities have been based on two ecological properties: dynamical stability and feasibility. The former is typically regarded as the capacity of a community to return to an original equilibrium state after a perturbation in species abundances and is usually linked to the strength of interspecific interactions. The latter is the...

Why are some plant–pollinator networks more nested than others?

Song, Chuliang ; Rohr, Rudolf P. ; Saavedra, Serguei

Empirical studies have found that the mutualistic interactions forming the structure of plant–pollinator networks are typically more nested than expected by chance alone. Additionally, theoretical studies have shown a positive association between the nested structure of mutualistic networks and community persistence. Yet, it has been shown that some plant–pollinator networks may be more...
