The outcome of many ecological interactions lies somewhere along a continuum between
pure positive and pure negative effects. Although the popularity of this idea has notoriously …

Coarse-grained rules are widely used in chemistry, physics and engineering. In biology,
however, such rules are less common and under-appreciated. This gap can be attributed to …

This work is related to dynamics of a discrete‐time 3‐dimensional plant‐herbivore model.
We investigate existence and uniqueness of positive equilibrium and parametric conditions …

Many mutualisms involve inter-specific resource exchanges, making consumer–resource
approaches ideal for studying their dynamics. Also in many cases these resources are short …

The conceptual framework for species interactions calls for a new perspective: conditional
outcomes are not rare; but, rather, closer to the norm. Interactions may shift or switch …

Shrubs of the Psychotria L.(Rubiaceae) genus can occur like a dominant species in the
understory of subtropical forests. This study aims to understand the ecological conditions of …

Organisms typically change their diets ontogenetically. Recent studies have shown that an
ontogenetic diet shift undermines the resilience of stage‐structured food webs. Here, we …

Coexistence of plants depends on their competition for common resources and indirect
interactions mediated by shared exploiters or mutualists. These interactions are driven either …

Fluid-feeding herbivores directly affect host plants through sap consumption. Moreover, they
establish mutualistic relationships with ants, which might generate additional reproductive …

Population structures largely affect higher levels of organization (community structure,
ecosystem functioning), especially when involving ontogenetic changes in habitat or diet …
