from the field to the lab

Announcing: Torreya – Tree of Life event!

The Florida Torreya, Torreya taxifolia, is in grave danger of disappearing from the wild. It’s range has shrunk to three counties on the Florida-Georgia border north of Tallahassee. Given this last opportunity to learn about the natural biome of a rare and beautiful conifer, a team of biologists will assemble at Torreya State Park on […]

FBRC annual meeting at Austin Cary

Today Dr. Hulcr, Dr. Smith and Dr. Carton de Grammont are at the Forest Biology Research Cooperative annual meeting talking about Forest Health and the role that ProForest plays in furthering collaborative research, extension and education. The meeting is at the beautiful Austin Cary Memorial Forest. Just a reminder of how a #health #managed #forest looks!

Redbay planting at Ordway-Swisher Biological Station

It was a cold and rainy north central Florida December day, but that didn’t slow down restoration planting of redbay seedlings at a protected site near Gainesville, FL. Strains of redbay that have displayed resistance to the laurel wilt pathogen were planted in the cool wet weather. They will be studied in the effort to […]

Survey at Torreya State Park

Biologists from the Florida Park Service and US FWS, conservation researchers from the Atlanta Botanical Gardens, local volunteers and the UF/SFRC Forest Pathology lab gathered in the panhandle of Florida on steep ravines near the Apalachicola River to survey pockets of the wild population of Torreya taxifolia.  Most of the previously mapped trees were found […]

No rest for the laurels: symbiotic invaders cause unprecedented damage to southern USA forests

Laurel wilt is an extraordinarily destructive exotic tree disease in the southeastern United States that involves new-encounter hosts in the Lauraceae, an introduced vector (Xyleborus glabratus) and pathogen symbiont (Raffaelea lauricola). USDA Forest Service Forest Inventory and Analysis data were used to estimate that over 300 million trees of redbay (Persea borbonia sensu lato) have succumbed […]

No rest on our laurels and please save the guac!

Cold tolerance range of Redbay Ambrosia Beetle overlaps range of Sassafras albidum.

Formby, J.P., Rodgers, J.C., Koch, F.H. et al. Biol Invasions (2017). Native Lauraceae (e.g. sassafras, redbay) in the southeastern USA are being severely impacted by laurel wilt disease, which is caused by the pathogen Raffaelea lauricola T. C. Harr., Fraedrich and Aghayeva, and its symbiotic vector, the redbay ambrosia beetle (Xyleborus glabratus Eichhoff). Cold temperatures are currently the […]

Growth phenology of loblolly pine from large genetic study.

Our postdoc Tania Quesada has been working on the genetics of growth in southern pine. Here is a new paper on the genetic architecture of shoot phenology in loblolly pine (Pinus taeda) from the CCLONES (Comparing Clonal Lines On Experimental Sites) study. Genetic control of growth and shoot phenology in juvenile loblolly pine (Pinus taeda L.) […]
