Pollination Strategy

Numerous orchid species are pollinated by food deception, where rewardless flowers attract foraging pollinators through the mimicry of other flowers or the use of non-specific floral signals. Here we investigate the pollination of Caladenia hildae, a member of a diverse Australian genus containing species pollinated by sexual deception, and species pollinated by food foraging pollinators. Despite eight bee species occurring at the main study site, only food foraging bees of a single species of Hylaeus (Colletidae) were observed to remove and deposit pollen of C. hildae. Spectral reflectance of C. hildae flowers differed from co-flowering rewarding species in terms of both the wavelengths of light reflected, and the pattern of colouration. As such, there was no evidence that C. hildae uses a pollination strategy based on floral mimicry. However, the attraction of only a single bee species at this site suggests that C. hildae may use a deceptive strategy that exploits sensory biases or behaviours that differ between Hylaeus sp. and the remainder of the bee community. While Hylaeus have been recorded visiting orchid flowers in several parts of the world, C. hildae may represent the first documented case of an orchid species specialised on pollination by Hylaeus bees.

We quantified inbreeding depression for seed maturation and germination in a deceptively pollinated orchid (Dactylorhiza praetermissa (Druce) Soó). Deceptive species do not provide any reward to their pollinators, which thus visit few flowers per plant. Therefore, deceptive species are predicted to experience high outcrossing. In agreement with the prediction that species with high outcrossing rate should possess a heavy genetic load, we demonstrated inbreeding depression in one of the populations we studied. More surprisingly, we found some evidence of inbreeding depression at a small geographic scale. This was not expected, as deceptive orchids generally disperse their pollen and their seeds over long distances. We also demonstrated that the position of a flower within an inflorescence interacts with the type of cross. This indicates that resource availability might modify how severely deleterious mutations affect reproductive success. This could also explain why the intensity of inbreeding depression seems, in the populations we studied, to be determined more by environmental factors than by inbreeding level, as estimated from molecular markers. Inferences in terms of conservation biology are drawn from these results.Key words: inbreeding depression, deceptive pollination, orchid, Dactylorhiza praetermissa.
