The aculeate wasps are one of the most diverse and speciose insect taxa; they are
omnipresent across ecosystems and exhibit diverse co‐evolutionary and exploitative …

Nectar, the main floral reward for pollinators, varies greatly in composition and
concentration. The assumption that nectar quality is equivalent to its sugar (energy) …

Woody climbers, vines, perennial herbs, trees or shrubs, more rarely annuals, sometimes
with large water-storing tubers or a xylopod, sometimes succulent, with large grappling …

The flora of southern Africa has exceptional species richness and endemism, making it an
ideal system for studying the patterns and processes of evolutionary diversification. Using a …

Specialization in plant pollination systems can arise from traits that function as filters of
flower visitors. This may involve chemical traits such as floral volatiles that selectively attract …

Plants with open flowers and exposed nectar should attract a wide diversity of flower visitors,
yet, for reasons that are not yet well understood, some plants with these 'generalist'floral …

Three morning glory species in the genus Argyreia Lour., A. lycioides (Choisy) Traiperm &
Rattanakrajang, A. mekongensis Gagnep & Courchet, and A. versicolor (Kerr) Staples & …

Abstract Background and Aims The extreme complexity of asclepiad flowers
(Asclepiadoideae–Apocynaceae) has generated particular interest in the pollination biology …

Exposed nectar presentation is a key trait in flowers specialized for pollination by short‐
tongued insects. We investigated the pollination of Satyrium microrrhynchum, a rare South …

Pollinator-mediated convergence in floral traits is the fundamental basis for pollination
syndromes, but it has seldom been rigorously analysed. Here we synthesize information on …
