Paleoclimatic modeling and phylogeography of least killifish, Heterandria formosa: insights into Pleistocene expansion-contraction dynamics and evolutionary history of North Americ... por Bagley, Justin C, Sandel, Michael, Travis, Joseph, Lozano Vilano, María de Lourdes, Johnson, Jerald B

“…Heterandria formosa, a wide-ranging regional endemic, presents an ideal system to test the expansion-contraction model within this biota. By integrating ecological niche modeling and phylogeography, we infer the Pleistocene history of this livebearing fish (Poeciliidae) and test for several predicted distributional and genetic effects of the last glaciation. …”

Hydroclimatic variations reveal differences in carbon capture in two concurrent conifers in northern Mexico por González Cásares, Marcos, Pompa García, Marín, Venegas González, Alejandro, Dominguéz Calleros, Pedro, Hernández Díaz, José Ciro, Carrillo Parra, Artemio, González Tagle, Marco Aurelio

“…A comparative analysis of tree species can expand the knowledge of the carbon cycle dynamics and ecological processes in this region. Here, we examined the growth, wood density, and carbon accumulation of two threatened species (Pseudotsuga menziesii and Cupressus lusitanica) to evaluate their hydroclimatic responsiveness.…”

Ecomorphological trajectories of reef fish sister species (Pomacentridae) from both sides of the Isthmus of Panama por Aguilar Medrano, Rosalía

“…The eastern Pacific and the Caribbean Sea were separated by the Isthmus of Panama ~ 3–6 Mya and allopatric speciation occurred on either side of the isthmus. Differences in ecological conditions on each side of the Isthmus of Panama separating the sister species may have shaped their niches and morphologies over evolutionary time. …”
