15 Μαρ 2024 · As plants undergo specialization, the differences between plants and animals become more pronounced, leading to distinct responses to radiation. Chronic radiation exposure may activate biological mechanisms resulting in increased radioresistance of the population.
Plant adaptive radiation examples are commonly insular, diversified in the Miocene or Pliocene, are associated with dispersal-mediated ecological opportunities, are polyploids, and have experienced hybridization. From those studies, a general model of plant insular adaptive radiation is proposed.
Here, we take a broad view of what constitutes an adaptive radiation, and seek to find commonalities among disparate examples, ranging from plants to invertebrate and vertebrate animals, and remote islands to lakes and continents, to better understand processes shared across adaptive radiations.

15 Μαρ 2024 · Presented in this review data demonstrate that ionizing radiation can change almost all aspects of plant life: the state of DNA, chromatin, and antioxidant system, patterns of gene expression, basic physiological processes, morphological parameters, and even the death of a plant.
17 Ιαν 2024 · Penstemon subgenus Dasanthera represents a microcosm adaptive radiation, with its 9 species exhibiting a diversity of ecological niches and floral pollination strategies.
2 Αυγ 2022 · Adaptive radiations represent some of the most remarkable explosions of diversification across the tree of life. However, the constraints to rapid diversification and how they are sometimes...
