Comment on "Cognition-mediated evolution of low-quality floral nectars".

چکیده
Nachev et al (Reports, 6 January 2017, p. 75) present dilute nectar in bat-pollinated plants as "paradoxical" because bats prefer concentrated nectar, but paradox disappears with realistic assumptions about nectar evolution. We argue that they make unrealistic assumptions about the cognitive abilities of bat pollinators, invoke Weber's law inappropriately, and cannot predict observed nectar concentrations of bat flowers or negative correlations between pollinator body size and average concentration.

Response to Comment on "Cognition-mediated evolution of low-quality floral nectars".
Pyke and Waser claim that our virtual pollination ecology model makes unrealistic assumptions and fails to predict observed nectar concentrations of bat flowers and negative correlations between pollinator body size and sugar concentration. In their comment, crucial model features are misrepresented, misunderstood, or ignored. Sensitivity to the supply/demand ratio explains both the equilibrium...
متن کاملCognition-mediated evolution of low-quality floral nectars.
Plants pollinated by hummingbirds or bats produce dilute nectars even though these animals prefer more concentrated sugar solutions. This mismatch is an unsolved evolutionary paradox. Here we show that lower quality, or more dilute, nectars evolve when the strength of preferring larger quantities or higher qualities of nectar diminishes as magnitudes of the physical stimuli increase. In a virtu...
متن کاملNectar and pollination drops: how different are they?
BACKGROUND Pollination drops and nectars (floral nectars) are secretions related to plant reproduction. The pollination drop is the landing site for the majority of gymnosperm pollen, whereas nectar of angiosperm flowers represents a common nutritional resource for a large variety of pollinators. Extrafloral nectars also are known from all vascular plants, although among the gymnosperms they ar...
متن کاملYeasts in nectar of an early-blooming herb: sought by bumble bees, detrimental to plant fecundity.
Through their effects on physicochemical features of floral nectar, nectar-dwelling yeasts can alter pollinator behavior, but the effect of such changes on pollination success and plant reproduction is unknown. We present results of experiments testing the effects of nectar yeasts on foraging patterns of captive and free-ranging bumble bees, and also on pollination success and fecundity of the ...
متن کاملThe Evolution of Social Cognition Development in Children whit Autism Spectrum and ADHD Disorders: A Systematic Review Study
Autism spectrum and attention-deficit/hyperactivity (ADHD) disorders are associated with widespread social cognitive impairments that affect their social relationships. In this regard, the present review study was conducted to investigate the development of social cognition in children with autism spectrum and ADHD disorders. In this systematic meta-analysis study, published articles on the dev...
