Mutualisms (cooperative interactions between species) have had a central role in the
generation and maintenance of life on earth. Insects and plants are involved in diverse forms …

Not all floral visitors attracted to flowers are pollinators. Instead, some visitors circumvent the
floral opening, usually removing nectar without contacting the anthers and/or stigma. Here …

Cheating is a focal concept in the study of mutualism, with the majority of researchers
considering cheating to be both prevalent and highly damaging. However, current …

Plants are under siege from a diversity of enemies that consume both leaf and floral parts.
Plants resist damage to leaves in a variety of ways, and we now have a rich literature …

Pollination by animals is critical to sexual reproduction of most angiosperms. However, little
is known about variation in pollination service to single plant species. We report results of a …

Nectar robbers use a hole made in the perianth to extract nectar. Since robbers may modify
plant fitness, they play an important role by driving evolution on floral traits, sha** …

Whence my possibly cryptic title? At the simplistic level that most of us first encounter plant-
pollinator relations—in a basic textbook, an introductory lecture, or a television documentary …

Social transmission of acquired foraging techniques is rarely considered outside of a
vertebrate context. Here, however, we show that nectar robbing by bumble-bees (Bombus …

Organisms experience a complex suite of species interactions. Although the ecological
consequences of direct versus indirect species interactions have received attention, their …

Honey bees and stingless bees are generalist visitors of several wild and cultivated plants.
They forage with a high degree of floral fidelity and thereby help in the pollination services of …
