Background and Aims Adaptation to different pollinators has been hypothesized as one of the main factors promoting the formation of newspecies in the Cape region of South Africa. Other researchers favour alternative causes such as shifts in edaphic preferences. Using a phylogenetic framework and taking into consideration the biogeographical ...


The experiment was conducted to study the effect of honey bee pollination and curd scooping on seed production of cauliflower (Brassica oleracea var. botrytis L.) cv. Poushali. Eighteen combinations of treatments comprising three types of pollination viz., open pollination (natural pollination), using bees for pollination...


Pollinators are a functional group with high relevance for ensuring cross‐pollination in wild plant populations and yields in major crops. Both pollinator declines and losses of pollination services have been identified in the context of habitat destruction and land use intensification. This editorial synthesizes and links the findings...


Seventeen distinct pollination systems are known for genera of sub-Saharan African Iridaceae and recurrent shifts in pollination system have evolved in those with ten or more species. Pollination by long-tongued anthophorine bees foraging for nectar and coincidentally acquiring pollen on some part of their bodies is the inferred ancestral...


The structural organization of mutualism networks, typified by interspecific positive interactions, is important to maintain community diversity. However, there is little information available about the effect of introduced species on the structure of such networks. We compared uninvaded and invaded ecological communities, to examine how two...


The York gum–jam woodlands of southwest Western Australia support diverse annual wildflower communities despite extensive habitat fragmentation, remnant isolation and the invasion of many exotic annual plant species. Few studies have explored the pollinator–plant relationships maintaining these persistently species-rich ‘novel’ communities. We...


Flowering plants often depend on the attraction of biotic pollinators for sexual reproduction. Consequently, the emergence and maintenance of selected floral attributes related to pollinator attraction and rewarding are driven by pollinator pressure. In this paper we explore the effect of pollinators, rainfall, temperature and air humidity on...


Our theoretical understanding of plant reproductive character evolution often onlyimplicitly includes pollinator behavior and the community ecological context of polli-nation. Reciprocal reservations apply to studies of pollinator evolution. I recast selectionmodels to incorporate interaction between plants of one species with the pollinators...
