The long and the short of it: a global analysis of hawkmoth pollination niches and interaction networks.
It is shown that pollinator proboscis length is a key niche axis for plants and can account for patterns of evolution in functional traits such as floral tube length and nectar volume, while pollinator niche breadth decreases according to the tube length of flowers.

The hypothesis that oligosulfides are universally effective signals by which deceptive flowers may effect pollen dispersal by attracting flies that use carrion or carnivore feces as brood sites is supported.

These findings are consistent with the idea that diffuse co-evolution drives the evolution of extremely long proboscises and flower tubes, and highlight the importance of morphological traits, beyond the forbidden links hypothesis, in structuring interactions between mutualistic partners, revealing that the role of niche-based processes can be much more complex than previously known.

Evidence from light-trapping of moths, pollen carriage on their bodies and moth scale deposition on stigmas suggests that sphingid pollination is prevalent only in the four populations with the longest flowers, in which floral morphological traits and nectar volumes match the classic expectations for the hawkmoth pollination syndrome.
Specialized use of pollen vectors by Caesalpinia gilliesii, a legume species with brush-type flowers
Results show that a pterotribic pattern of pollen deposition on the body of long-tongued hawkmoths is operating in this species, which suggests that brush-type blossoms are not necessarily unspecialized, despite popular belief.

The findings indicate that pollinator-mediated selection may vary through time and space according to local variations in pollinator assemblages, and Phenotypic selection is dependent on the mutual match between pollinator and flower morphologies.
RESTRICTION OF POLLINATOR ASSEMBLAGE THROUGH FLOWER LENGTH AND WIDTH IN THREE LONG-TONGUED HAWKMOTH–POLLINATED SPECIES OF MANDEVILLA (APOCYNACEAE, APOCYNOIDEAE)1
It is tested how the corolla tube length and operative width required for effective release of the pollination mechanism could restrict the pollinator assemblage in putatively hawkmoth-pollinated Apocynaceae that differ in flower depth.

The results suggest the presence of a hybrid swarm between sympatric M. pentlandiana and M. laxa and indicate that initial hybridisation events between these parental species are rare, but once they occur, visits between putative hybrids and M-laxa are common and facilitate continued introgression.

Gland anatomy and position on the outside of the perianth are unusual for scent glands in general, suggesting that wound volatiles are utilised as kairomonal attractants by florivores whose activities result in pollination.
Chromosomal changes and recent diversification in the Andean genus Jaborosa (Solanaceae)
The diversification of Jaborosa seems to be correlated with the most recent uplifts in the Andes in central South America and the establishment of the Patagonian steppe: the genus colonized these biomes and, at the same time, underwent a remarkable chromosomal and morphological differentiation.
