“…Our findings are consistent with Pritzkow et al [21] and Henn et al [50], indicating high phenotypic plasticity and its consequences for performance within a species is adaptive. Theoretically, adaptive phenotypic plasticity should be more extensive in species experiencing environmental heterogeneity over the course of a generation and those potentially having wider fundamental niches [38,51]. Consequently, the adaptive phenotypic plasticity of leaf functional traits, such as LA and LUE in tetraploid; LA, WUE, and LUE in octaploid, are critical for the species' survival in the B. macrostachya complex.…”

Leaf functional traits reflect species’ adaptive strategies and habitat requirements. Examining intra-specific variations and their underlying drivers can aid in comprehending species differentiation and adaptation. Here, we investigated the leaf functional traits of Buddleja macrostachya tetraploids and octaploids across 18 sites in the Sino-Himalayan region. The habitat environmental variables were also recorded. In this study, leaf functional traits showed a considerable differentiation in both tetraploid and octaploid B. macrostachya. Redundancy analysis (RDA) revealed that the octaploid cytotypes displayed higher specific leaf area, leaf total nitrogen and phosphorus concentrations, water-use efficiency, and light-use efficiency in contrast to the tetraploid plants. These functional leaf traits exhibited different plasticity levels in both taxa. A positive link was found between habitat altitude and soil total P concentration and the geographic distribution of the B. macrostachya complex, using RDA and Pearson’s correlation. Our findings suggest that both tetraploid and octaploid B. macrostachya exhibited divergent ecological strategies, conservative and acquisitive strategies, respectively. The ecological adaptability of species within the B. macrostachya complex is enhanced by the combination of divergent ecological strategies and high phenotypic plasticity of distinct key ecological traits. Furthermore, abiotic environmental factors influenced the allopatric geographic distribution pattern of the B. macrostachya complex in the Sino-Himalayan region.

PremiseStudies into the evolution and development of leaf shape have connected variation in plant form, function, and fitness. For species with consistent leaf margin features, patterns in leaf architecture are related to both biotic and abiotic factors. However, for species with inconsistent leaf shapes, quantifying variation in leaf shape and the effects of environmental factors on leaf shape has proven challenging.MethodsTo investigate leaf shape variation in a species with inconsistently shaped leaves, we used geometric morphometric modeling and deterministic techniques to analyze approximately 500 digitized specimens of Capsella bursa‐pastoris collected throughout the continental United States over 100 years. We generated a morphospace of the leaf shapes and modeled leaf shape as a function of environment and time.ResultsLeaf shape variation of C. bursa‐pastoris was strongly associated with temperature over its growing season, with lobing decreasing as temperature increased. While we expected to see changes in variation over time, our results show that the level of leaf shape variation was consistent over the 100 years.ConclusionsOur findings showed that species with inconsistent leaf shape variation can be quantified using geometric morphometric modeling techniques and that temperature is the main environmental factor influencing leaf shape variation.

SUMMARYSympatric species often adapt to distinct microhabitats, leading to reproductive isolation and phenotypic diversity. However, temporal variation in selection may cause local maladaptation and species boundary breakdown, especially in years with large climatic events leading to episodic selection. Repeated reciprocal transplants can reveal short and long-term patterns of natural selection.To examine evolutionary trajectories of sympatric Monkeyflowers adapted to different niches,Mimulus guttatusandM. laciniatus,we performed three replicated transplants and combined them with previous experiments to leverage a dataset of five transplants spanning 10 years. We performed phenotypic selection analyses on parents and hybrids in parental habitats in Yosemite NP, CA during years of differing snowpack. If there is ecological isolation, then we predicted local adaptation and divergent phenotypic selection between habitats in line with species’ differences.We found interannual fluctuations in selection, often not in predicted directions. Episodic selection due to extreme high snowpack caused a reversal of local adaptation and contributed to overall maladaptation ofM. guttatus. However, a combined-year analysis detected longer-term divergent selection on flowering time, a key temporally isolating and adaptative trait, in agreement with species’ differences.In conclusion, even with annual fluctuations, longer-term divergent selection may still promote species boundaries.
