Hope for California’s Endemic Oaks in a Changing Climate: Further Research

By Steve Potter | August 14, 2026
The provenance trial indicated that valley oak growth declines across much of the low-elevation inland range, and growth increases in several coastal and high-elevation regions under a high-emissions scenario.  Figure from Sork et al. (2026).
Two new papers by Dr. Victoria Sork and colleagues

Research Roundup

Figure 1: Iberian White oaks sampling distribution. Sampling locations are placed above the main biogeographic lifezones obtained by modelling deciduous (Temperate-Eurosiberian) and brevi-deciduous/marcescent (Submediterranean) oaks, with the overlap of both lifezones considered to be transitional (Eurosiberian-Submediterranean). Squares represent true roburoid oaks and circles represent former Sect. Dascia and Sect. Galliferae species. Adapted from Vila-Viçosa et al. (2019). Taxon labels reflect the origin
Summaries of research papers related to oaks that have come to our attention and which may be of interest to members.

Epigenetics as a Potential Mechanism of Rapid Response to Climate Change in the Endangered Oak Quercus hinckleyi

By Website Editor | June 9, 2026
Lainey Kirshberger and Ryan Silver, students at Oklahoma State University, participated in the fieldwork and will lead the genetic and epigenetic analysis under the supervision of Dr. Antonio R. Castilla.
Endangered oak Quercus hinckleyi shows strong genetic diversity and clonal resilience, making conservation of both genetic and epigenetic variation vital for adapting to climate change.
