Fieldwork in Monahans Sandhills State Park, one of the study sites for our research focused on how local adaptation and hybridization shape genetic variation in shinnery oak—a foundational species that stabilizes sand dunes in the south-central US.

Here are some photos from our fieldwork at Big Bend Ranch State Park! We collected leaf samples from Quercus hinckleyi to investigate epigenetic variation within populations. This research is supported by the International Oak Society.

To what extent do novel fire regimes generate trait-fire regime mismatches?

Fieldwork in western OK! Today we scouted for shinnery oak populations in Quartz Mountains and surroundings. What a cool place Quartz Mountains State Park! Finally, we found our study population near Blair. Ryan has another piece of information for his assessment of the species’ genomic variation!

Describing the phenotype of a long-lived plant can be tricky. My recent paper in @eco-aeet.bsky.social shows that shapes of lifetime fecundity schedules of individual lavender shrubs differ widely among individuals and is subject to phenotypic selection [paper in English]

doi.org/10.7818/ECOS...
El fenotipo de las plantas como una trayectoria: seguimiento de 38 años revela que la historia vital de fecundidad está bajo selección en un arbusto mediterráneo | Ecosistemas
La definición de un fenotipo resulta a veces problemática para organismos no unitarios de estructura modular y crecimiento indeterminado, como son las plantas. Este artículo presenta una prueba de concepto de la importancia evolutiva de considerar las trayectorias de vida de plantas individuales como un elemento de sus fenotipos. Durante un período de 38 años se registró el tamaño de la planta y la producción de inflorescencias durante toda la vida reproductiva de N = 128 individuos del arbusto leñoso mediterráneo Lavandula latifolia (Lamiaceae) para abordar las siguientes preguntas: ¿Existieron diferencias entre individuos en sus trayectorias vitales de tamaño y fecundidad?, ¿Los parámetros que describen las trayectorias individuales estuvieron relacionados con la reproducción acumulada durante la vida? Los individuos difirieron ampliamente en fecundidad acumulada a lo largo de la vida y en cada uno de los parámetros empleados para describir el cronograma de fecundidad a lo largo de la vida (edad en la primera y última reproducción, longevidad, y la media, varianza, asimetría y curtosis de la distribución temporal de la producción de inflorescencias a lo largo de la vida). El análisis de selección fenotípica reveló relaciones significativas entre los parámetros que describen los programas de vida individuales y la estima empleada para describir la aptitud relativa de los individuos (producción acumulada de inflorescencias durante toda la vida dividida por el promedio de todos los individuos). Los gradientes de selección obtenidos demostraron la existencia de selección direccional positiva y negativa, así como casos de selección no lineal sobre algunas variables. Ello vino a demostrar que plantas cuyas curvas de fecundidad durante la vida poseen ciertas formas tenían una ventaja de aptitud sobre las otras. Estos resultados apoyan la idea de que la forma de las trayectorias vitales de las plantas individuales conforma parte de sus fenotipos.
