Do plants with multiple pollinators evolve unique trait combinations or intermediate phenotypes compared to plants with onepollinator? Using experimental evolution, Schiestl et al. (2018) found that plants pollinated by bumblebees and hoverflies evolvedtrait values not observed in plants pollinated by one taxon, which provides evidence for the...


A few fundamental experiments were carried out to increase information about the incompatibility of Japanese pear (Pyrus serotina R.). The results obtained are summarized as follows.  1. Flowers of `Kosui' at anthesis were self- or cross-pollinated after emasculation, and pollen germination on stigmas at 6 h after pollination was observed....


Pollinators are an innocent casualty of the war on insects. Noted 50 years ago by Rachael Carson in her book Silent Spring, and continuing to arouse great concern in natural science and agriculture, the unintended biocide poisoning of wildlife persists. The insects, many of the bees, sustain agriculture and wildlands by collectively allowing...


Increased incidence of landscape fire and pollinator declines with co-extinctions of dependent plant species are both globally significant. Fire can alter species distributions, but its effects on plant–pollinator interactions are poorly understood so its present and future role in coupled plant–pollinator declines cannot be assessed. * We...


The thematic assessment of pollinators, pollination and food production carried out under the auspices of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services aims to assess animal pollination as a regulating ecosystem service underpinning food production in the context of its contribution to nature’s gifts to...


Apple plays an important role in the livelihood of the farming community in Chitral, Pakistan. The commercial varieties of apple planted in orchards in Chitral, for example, Kala Kola (Red Delicious), Choupush (Royal Delicious), and Royal Gala, are reported to be partially or completely self-incompatible and require crosspollination for...


A decline of wild pollinators, along with a decline of bee diversity, has been a cause of concern among academics and governmental organizations. According to IPBES, a lack of wild pollinator data contributes to difficulties in comprehensively analyzing the regional status of wild pollinators in Africa, Latin America, Asia and Oceania. It may...
