Intraspecific variation in stomatal architecture, gas exchange, & #drought response of a dominant #prairie #grass sourced from broad climatic gradients

New #AJB research by @j-sytsma-56.bsky.social, Allison Ricker, Helen Winters, Brian Maricle et al.

doi.org/10.1002/ajb2... #botany #plantscience
Conceptual diagram illustrating how climate influences stomatal traits and drought responses in Andropogon gerardii. The top panel compares populations: warm, dry environments are shown with leaves having smaller, more numerous stomata to reduce water loss, while cool, moist environments have leaves with larger, fewer stomata that enhance transpiration. The bottom panel depicts drought responses: dry-adapted populations maintain similar stomatal traits and continue carbon gain (drought tolerant), whereas wet-adapted populations show pronounced stomatal closure or reduction in size and density, leading to lower photosynthesis (drought susceptible).

Front, side, and dissected view photographs of anthesis flowers from Nicotiana section Repandae allopolyploids (N. nudicaulis, N. repanda, and N. stocktonii) and their diploid progenitors N. sylvestris and N. obtusifolia. Nicotiana nudicaulis also has side view flower bud photographs at Stage 1, Stage 2, and Stage 3, which represent 60%, 85%, and 95% of anthesis length, respectively. Nicotiana nudicaulis and N. repanda have transgressive delphinidin pigmentation not found in either progenitor.

Lichens have recolonized some urban areas following reductions in air pollution. These reurbanized lichen populations are ideal models of urban evolution. This image shows several urban lichens, including Physcia millegrana and Candelaria concolor, growing on an oak tree, Quercus rubra, in Long Island City, New York. See Ann M.
