Molecular genetic characterization of the koa-wilt pathogen (Fusarium oxysporum): Application of molecular genetic tools toward improving koa restoration in Hawai'i

Publications Posted on: June 23, 2016
Several forest diseases are causing serious threats to the native Hawaiian forest. Among them, koawilt disease (caused by Fusarium oxysporum) is damaging to native populations of koa (Acacia koa), and it also hinders koa restoration/reforestation. Because F. oxysporum likely represents a complex of species with distinct pathogenic activities, more detailed characterization is needed to better understand the F.

Stocktype and grass suppression accelerate the restoration trajectory of Acacia koa in Hawaiian montane ecosystems

Publications Posted on: March 29, 2016
Restoring degraded mesic-montane forests represents a major challenge in maintaining functioning ecosystems throughout the tropics. A key example of this lies in Hawai‘i, where restoring native koa (Acacia koa, A. Gray) forests are a top conservation and forestry priority because of the critical habitat and high-value timber products that they provide.

Preliminary survey of wood-associated fungi in southeast O'ahu of Hawai'i using DNA-based identification

Publications Posted on: March 26, 2016
Hawai'i is a biological hotspot with a variety of climates and habitats. While fungal species diversity has been more extensively studied in Hawai'i than other Pacific Islands (e.g. see Gilbertson et al. 2002), there remain many species unreported in the literature. This project attempted to capture a small portion of Hawai'i's fungal diversity in southeast O'ahu by identifying fruit bodies using molecular techniques.

Early field performance of Acacia koa seedlings grown under subirrigation and overhead irrigation

Publications Posted on: November 17, 2011
Koa (Acacia koa A. Gray [Fabaceae]) seedlings were grown with subirrigation and overhead irrigation systems in an effort to characterize post-nursery field performance. One year following outplanting, we found no differences in seedling height or survival, but root-collar diameter was significantly larger for subirrigated seedlings.
