Given that flower size and pigmentation can mediate plant–pollinator interactions, many studies have focused on pollinator-driven selection these floral traits. However, precipitation, temperature, solar radiation also contribute to geographic variation in traits within multiple species. Several described an ecogeographic pattern which (within species) high ultraviolet (UV) radiation, low precipitation and/or latitudes are associated with increased anthocyanin production, smaller flowers,...
Abstract Some economically important crop species are dioecious, producing pollen and ovules on distinct, unisexual, individuals. On-the-spot diagnosis of sex is to breeders farmers for improvement maximizing yield, yet diagnostic tools at the seedling stage understudied lack a scientific basis. Understanding sexual dimorphism in juvenile plants may provide key ecological, evolutionary economic insights into dioecious plant addition improving process cultivation. To address this gap...
Abstract The movement of plant species across the globe exposes native communities to new introductions. While introductions are pervasive, two aspects variability underlie patterns and processes biological invasions at macroecological scales. First, only a portion introduced become invaders capable substantially impacting ecosystems. Second, that do invasive one location may not be in others; impacts depend on invader abundance recipient conditions. Accounting for these phenomena is...
Abstract The evolution of seed size may be influenced by intrinsic attributes populations, such as mating system and extrinsic factors, climate. Several hypotheses propose that the self‐fertilization from an outcrossing progenitor will accompanied a reduction in size, but this prediction has not been rigorously tested. Many studies report mean populations or taxa is associated with long‐term climate conditions. Here, we examined effects on both within single genus. In California wildflower...
Premise of the Study Wild plant species that require services pollen‐feeding insects for reliable pollination may evolve features attract and reward their mutualistic partners. Heterantherous have been proposed to exhibit a “division labor” whereby “feeding anthers” (which produce pollen be consumed by an insect) are distinguished from “reproductive more likely contribute reproduction). In some heterantherous species, including Clarkia unguiculata (Onagraceae), these two anther types differ...
The era of high-throughput techniques created big data in the medical field and research disciplines. Machine intelligence (MI) approaches can overcome critical limitations on how those large-scale sets are processed, analyzed, interpreted. 67th Annual Meeting Radiation Research Society featured a symposium MI to highlight recent advancements radiation sciences their clinical applications. This article summarizes three presentations regarding developments for metadata processing ontological...
Abstract Many angiosperms are hermaphroditic and produce bisexual flowers in which male (pollen export) female (stigma receptivity) functions separated temporally. This sequential hermaphroditism may be associated with variation flower size, color, or pattern, all of influence pollinator attraction. In this study, we describe these traits across discrete functional sex stages within between 225 greenhouse‐grown individuals Clarkia unguiculata (Onagraceae). addition, to identify the effects...
Premise Strong correlations between traits can obscure their independent effects on components of reproduction. Style length ( SL ) and petal area PA vary within species, for example, but the opportunity selection among pollen genotypes are poorly understood. Previous work in Clarkia detected a positive effect receipt, potentially intensifying selection. However, this apparent may be influenced by correlated trait, such as . Here, we examine these two receipt performance. Methods We...
