Data from: Functional implications of the specialized staminal appendages in alpine ginger (Roscoea spp.: Zingiberaceae)
<p>Floral organs are widely believed to enhance the pollination and reproductive success of angiosperms. However, the functional implication of some floral structures is still unknown. In this study, we explored the functional role of staminal appendages on male and female fitness of Himalayan Roscoea spp. and tested if their function differed between species with biotic pollination and autonomous selfing. Phenotypic manipulation is a powerful approach to test the functional effect of a particular trait on plant fitness. We compared various proxies of pollination success between intact flowers and flowers with manually-excised staminal appendages. We found that the rate of visitation did not differ between intact and manipulated flowers. Our results revealed that in outcrossing Roscoea spp. the staminal appendages act as triggering devices to facilitate pollen release and deposition and also to manipulate the foraging position of pollinators to ensure both male and female fitness. In contrast, in autonomously selfing Roscoea spp., the removal of staminal appendages did not affect any aspect of pollination processes. Our results suggest that the staminal appendages are an integral component of outcrossing in Roscoea spp., and are maintained by selection pressure through both male and female fitness. This study provides important insights on how variation in breeding systems can provoke changes in the structure and function of floral organs among congeners.</p>
Data from: Rapid divergence of nesting depth and digging appendages among tunneling dung beetle populations and species
Many dung beetle communities are characterized by species that share very similar morphological, ecological, and behavioral traits and requirements yet appear to be stably maintained. Here, we document that the morphologically nearly indistinguishable, sympatric, and syntopic tunneling sister species Onthophagus taurus and Onthophagus illyricus may be avoiding competitive exclusion by nesting at remarkably different soil depths. Intriguingly, we also find rapid divergence in preferred nesting depth across native and recently established O. taurus populations. Furthermore, geometric morphometric analyses reveal that both inter- and intraspecific divergences in nesting depth are paralleled by similar changes in the shape of the primary digging appendages, the fore tibiae. Collectively, our results identify preferred nesting depth and tibial shape as surprisingly evolutionarily labile and with the potential to ease interspecific competition and/or to facilitate adaptation to local climatic conditions.
