The successful cultivation of insect-pollinated mass-flowering crops (MFCs) largely depends on the visiting frequency of different insect pollinator species in the blooming period of these crops1,2,3. It has been shown that the structure of the landscape surrounding fields of MFCs can have a sig...
Diurnal and nocturnal plant-flower visitor networks (hereafter, plant-pollinator networks) were built for each site during the flowering season of 2010 (Picos de Europa) and 2011 (Sierra de Guadarrama and Sierra Nevada). To build the diurnal networks, interactions between plants and floral visitors...

The orchid family contains some of the most specialized insect-pollinated flowers of all and has more species (at least 24,000) than any other plant family. Other groups of angiosperms re-evolved the ability to be pollinated by wind. One of these groups—the grasses—appeared about 50 mill...
Genetic diversity, genetic structure, and gene flow in plant populations and their influencing factors are important in conservation biology. Cypripedium macranthos is one of the few wild orchids with high ornamental value in northern China. However, ove
2) Is there evidence of gene-flow between populations, especially between domesticated and wild populations of the cowpea gene pool? Both questions appear critical in the light of the forthcoming deployment of GE insect-resistant cowpea in West African countries....

Each flower has one ovule and when pollinated it is open for one day. Seeds of A. maritima are dispersed enclosed in the calyx. The upper part of the calyx is membranaceous (area 0.25 cm2) and bends back when the seed ripens, thus functioning as a parachute-like structure (Fig. 1)...
Various biotic and abiotic factors are known to exert selection pressures on floral traits, but the influence of ultraviolet-B (UV-B) light on the evolution of flower structure remains relatively unexplored. We have examined the effectiveness of flower s
keteleeri, a self‐incompatible and insect‐pollinated shrub, during different developmental stages of flowers. In addition, pollinator visitation rates and fruit set were determined in intact inflorescences and those with sterile flowers removed. The results indicate that sterile and fertile flowers ...
