“…In contrast, the study by Crisp and Cook (2011) proposed that the timing of cycad genera diversification must have occurred earlier in the Paleogene (earlier than 23.03 Ma). Subsequent studies (e.g., Calonje et al, 2019;Condamine et al, 2015;Dorsey et al, 2018;Liu, Wang, et al, 2022;Mankga et al, 2020;Medina-Villarreal et al, 2019;Salas-Leiva et al, 2013) supported the "Neogene diversification" hypothesis, whereas some others (Coiro et al, 2023;Gutiérrez-Ortega, Pérez-Farrera, Matsuo, et al, 2023;Gutiérrez-Ortega, Salinas-Rodríguez, Martínez, Molina-Freaner, et al, 2018;Gutiérrez-Ortega, Yamamoto, Vovides, Pérez-Farrera, et al, 2018;Liu, Lindstrom, et al, 2022) supported the "Paleogene diversification" hypothesis. These two hypotheses are compatible, respectively, with the hypotheses of recent dispersal by Gregory and Chemnick (2004) and the ancestral dispersal by Sabato and De Luca (1985) mentioned above.…”

“…However, disparate local environmental pressures may allow species to shift/drift toward distinct ecological tolerances over time, at macroevolutionary scale. Clarifying such trends among closely related species can contribute to clarify the factors shaping the evolution of Dioon throughout its wide distribution range, but unfortunately, studies applying ENMs in Dioon are almost non-existent (only in Gutiérrez-Ortega et al, 2020;Gutiérrez-Ortega, Molina-Freaner, et al, 2021;Rubio-Méndez et al, 2020), and are very limited in cycad research in general (only in Bamigboye & Tshisikhawe, 2022;Carvajal-Hern andez et al, 2020;Gutiérrez-Ortega, Pérez-Farrera, Lopez, & Vovides, 2023;Gutiérrez-Ortega, Pérez-Farrera, Matsuo, et al, 2023;Laidlaw & Forster, 2012;Martínez-Domínguez et al, 2021;Mudannayake et al, 2019;Pradhan & Chettri, 2017;Swart et al, 2018). Here, we aim to fill that knowledge gap by following a common method, as we describe below, to construct ENMs by using geographic coordinates of localities where Dioon populations occur and environmental data obtained from geographic information systems.…”

Cycads represent an example of the success of evolutionary stasis. Despite their early origin, they survived multiple events of mass extinction and diversified in modern tropical ecosystems during the Cenozoic without major changes in their morphology. What factors have allowed their persistence and diversification despite their conservative nature? We reviewed documentation on the micro‐ and macro‐evolutionary processes involved in the diversification of the Neotropical genus Dioon. Dioon comprises 18 species from varied habitats in Mexico and Honduras, and serves as a model to understand the patterns of cycad diversification. Here, we synthesize evidence reached from different fields, especially biogeography, phylogenetics, population ecology, and speciation, to propose a mechanism that can explain the current patterns of biodiversity in Dioon. At the macroevolutionary scale, a Paleogene origin for Dioon is more likely than an alternative hypothesis of a Neogene origin. Dioon lineages have dispersed along with the expansion of tropical forests throughout main mountain chains. Subsequently, climate change, and particularly aridification, promoted the fragmentation of the tropical forests, allowing the main Dioon clades to evolve in isolation at distinct biogeographic regimes. At the microevolutionary scale, low seed dispersal capability, stochastic demographic processes, and niche conservatism restrict the lineages to isolate themselves at narrow habitats, promoting local adaptation in populations. Local adaptation seems to be a process achieved through many generations under stabilizing selection. Altogether, these processes shaped the diversification in Dioon. This review attempts to stimulate further research on cycads and other biological groups that have diversified despite their apparent evolutionary stasis.

In this study, the influence of geographic isolation on the levels of morphological and genetic differentiation among populations of the karst forest-adapted Pilea pteridophylla (Urticaceae) was evaluated. Based on our results, there is a strong morphological differentiation among the only two know populations of Pilea pteridophylla. Both populations can be clearly differentiated based on vegetative and reproductive characters, and the observed variation is geographically structured. Moreover, our genetic data from the chloroplast genome show strong levels of population differentiation and no shared haplotypes were observed between populations. Also, our estimation of divergence times supports a long-term isolation hypothesis between populations. Based on our results, dispersal seed limitation, long-term forest isolation and topographic heterogeneity (local adaptation) are related to high levels of endemism and species turnover in the mountain karst forests of Mexico.
