Breeding system, pollinator choice and variation in pollen quality in British herbaceous plants
1. Although it is well established that different plant species vary considerably in the quality of pollinator rewards they offer, it is unclear how plant reproductive systems, in particular an obligate dependence on insects for pollination, might influence the evolution of pollinator rewards. Moreover, unlike the interaction between nectar reward and pollinator visitation, we have a limited un...
متن کاملEffects of small-scale clustering of flowers on pollinator foraging behaviour and flower visitation rate
Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...
متن کاملEasy access to antifungal agents.
Vulvovaginal candidiasis is a common problem; at one time or another most women experience at least one episode of this bothersome condition. For the past several years, the pharmaceutical industry has convinced women that this condition is easily treated and that they should recognize the symptoms of vulvovaginal candidiasis. Thus women have had access to a variety of intravaginal antifungal a...
متن کاملPollinator-induced twisting of flowers sidesteps floral architecture constraints
Specific pollen placement by zygomorphic flowers on pollinators is one of the key innovations of angiosperm evolution [1]. In most phylogenetic lineages that have evolved zygomorphic flowers, reproductive organs are positioned either in the lower or upper part of the flower. Although these specific positions largely enhance pollen economy, they also represent architectural constraints such that...
متن کامل15 Demographic Senescence in Herbaceous Plants
For herbaceous plants, in contrast to many higher animals but similarly to other modular and sedentary life forms, it is not so much a question of how senescence progresses as it is a question of whether senescence occurs at all for most species. Overall, both the empirical evidence and theoretical predictions provide contrasting evidence. Monocarpic species and other semelparous life forms are...
