The evolution of mutualism with modifiers [PDF]

, 2017
Mutualisms are widespread, yet their evolution has received less theoretical attention than within-species social behaviors. Here, we extend previous models of unconditional pairwise interspecies social behavior, to consider selection for donation but ...

Elevated carbon dioxide increases nectar production in Epilobium angustifolium L [PDF]

, 2018
Effects of elevated CO2 and nutrient availability on nectar production and onset of flowering in five different seed families (genotypes) of Epilobium angustifolium were investigated in a greenhouse experiment. Elevated CO2 significantly increased nectar

Pollination ecology of the invasive tree tobacco Nicotiana glauca: comparisons across native and non-native ranges

Journal of Pollination Ecology, 2012
Interactions with pollinators are thought to play a significant role in determining whether plant species become invasive, and ecologically generalised species are predicted to be more likely to invade than more specialised species.

Testing how antagonistic interactions impact the robustness of plant-pollinator networks

Journal of Pollination Ecology, 2019
Given ongoing pollinator declines, it is important to understand the dynamics of linked extinctions of plants driven by pollinator extinctions. Topological robustness models focused on this question suggest relatively high robustness of plant species to ...

Nectar Production by Invasive Lantana camara and Endemic L. peduncularis in the Galápagos Islands [PDF]

, 2012
Measurements of nectar volume and sugar concentration along two elevational gradients, in flower exclusion experiments, and over a diurnal cycle of nectar production, were compared for invasive Lantana camara and endemic Lantana peduncularis in the ...

Native bees (Hymenoptera: Apoidea) and berry polycultures: Studying farmers’ motivations for diversification and the impact of mass floral resources on pollinator communities [PDF]

, 2017
Floral resource continuity is an important component in pollinator conservation. Mass blooms early in the season may bolster pollinator communities on sequentially flowering crops by creating a resource pulse in an agricultural landscape.
