As prey and pollinators, insects increase reproduction and allow for outcrossing in the carnivorous plant <i>Dionaea muscipula
American Journal of Botany.
author keywords: carnivorous plants; Dionaea muscipula; Droseraceae; plant-insect interactions; pollination; pollination ecology; reproductive biology; resource limitation
TL;DR:
This study reinforces the reliance of D. muscipula on adequate prey capture for flower, fruit, and seed production and a mobile pollen vector for reproduction, indicating the importance of considering insects as part of an effective conservation management plan for this species.

MeSH headings : Animals; Bees; Female; Flowers; Humans; Lupinus; Male; Plant Nectar; Pollen; Pollination; Reproduction; Reward
TL;DR:
The results suggest that a pollen-only reward strategy may allow plants that are visited by pollen foragers to minimize some costs of reproduction by eliminating investment in other rewards, such as nectar, without compromising female plant fitness.

Oikos, 127(11), 1679–1689.
author keywords: nectar robbing; commensalism; Corydalis caseana; plant reproduction
TL;DR:
Three mechanistic hypotheses that can explain when interactions between plants and nectar‐robbers should be commensal rather than antagonistic are outlined: the non‐discrimination (pollinators do not avoid robbed flowers), visitor prevalence (robber visitation is rare relative to pollinator visitation), and pollen saturation (stigmas receive sufficient pollen to fertilize all ovules with one or very few pollinator visits) hypotheses.

Linking economic activities to the distribution of exotic plants
Proceedings of the National Academy of Sciences, 101(51), 17725–17730.
author keywords: human population; invasion biology; real estate; species distributions; structural equation model
MeSH headings : Ecosystem; Models, Economic; Plant Development; Population Dynamics
TL;DR:
A hypothesis that links ecology and economics to provide a causal framework for the distribution of exotic plants in the United States shows that economics matter for resolving the exotic-species problem because the underlying causes, and some of the solutions, may lie in human-economic behaviors.

Optimal defence theory and flower petal colour predict variation in the secondary chemistry of wild radish
Journal of Ecology, 92(1), 132–141.
TL;DR:
Petal colour variants differed in their induced responses to damage, but not in their constitutive levels of compounds, and individual glucosinolates differed in both their degree of inducibility as well as in their distribution between tissue types.

THE DUAL ROLE OF FLORAL TRAITS: POLLINATOR ATTRACTION AND PLANT DEFENSE
Ecology, 85(6), 1503–1511.
TL;DR:
Data is presented showing that a nectar trait (dilute nectar) might directly and indirectly benefit plant fitness by deterring nectar-robbing bumble bees of Ipomopsis aggregata without deterring hummingbird pollinators.

THE ROLE OF HERBIVORES IN THE MAINTENANCE OF A FLOWER COLOR POLYMORPHISM IN WILD RADISH
Ecology, 84(7), 1733–1743.
TL;DR:
The data presented here suggest that differential preference and performance of herbivores for R. sativus color morphs may counter selection on flower color exerted by pollinators.

Direct and ecological costs of resistance to herbivory
Trends in Ecology & Evolution, 17(6), 278–285.
TL;DR:
It is found that many more studies have documented costs of resistance (sensu lato) than found during the 1996 survey and that eighty-two percent of studies in which genetic background is controlled, demonstrate significant fitness reductions associated with herbivore resistance.

Variation in the interactions between a nectar-robbing bumblebee and its host plants may have important consequences with respect to the population dynamics of host plants as well as selection on floral and flowering traits.

Volatile Production by Buds and Corollas of Two Sympatric, Confamilial Plants, Ipomopsis aggregata and Polemonium foliosissimum
Journal of Chemical Ecology, 28, 565–578.
TL;DR:
Differences in volatile production between I. aggregata and P. foliosissimum buds and corollas and differences in volatiles are consistent with selection pressures exerted by organisms interacting with these plants.

Field and allozyme studies investigating optimal mating success in two sympatric spring-ephemeral plants, Trillium erectum and T. grandiflorum
Heredity, 87(2), 178–189.
TL;DR:
The lack of optimal outcrossing distances and the patterns of allozyme variation in T. erectum and T. grandiflorum populations may be attributed to a number of factors, including active seed dispersal by ants, rare long-distance gene-flow events, post-pollination and post-fertilization selection, and/or the severity of inbreeding depression.

The impact of floral larceny on individuals, populations, and communities
Oecologia, 129(2), 161–168.
TL;DR:
A meta-analysis on existing studies shows that larceny has an overall detrimental effect on female reproductive success of plants, and that effect size depends on the types of robbers, thieves, and pollinators that interact as well as on the reproductive biology of the plant.

A trade-off between the frequency and duration of bumblebee visits to flowers
Oecologia, 117(1-2), 161–168.
TL;DR:
The potential for a trade-offs between these two components of pollinator service exists when visit duration depends on reward quantity; whether the trade-off is realized will depend on variation in nectar production and on whether pollinators forage systematically.

TL;DR:
The results indicate that hummingbird avoidance of nectar-robbed plants and flowers reduces plant fitness components and suggests that the mutualisms between pollinators and host plants may be affected by other species, such as nectar robbers.
