Hawaiʹi’s most widespread native tree, ʹōhiʹa lehua (Metrosideros polymorpha), has been dying across large areas of Hawaiʹi Island mainly due to two fungal pathogens (Ceratocystis lukuohia and Ceratocystis huliohia) that cause a disease collectively known as Rapid ʹŌhiʹa Death (ROD). Here we examine patterns of positive detections of C. lukuohia as it has been linked to the larger mortality events across Hawaiʹi Island. Our analysis compares the environmental range of C. lukuohia and its spread over time through the known climatic range and distribution of ʹōhiʹa. This data release consists of two rasters, one containing the projected suitability for C.lukuohia and another consisting of modeled presence/absence across the main Hawaiian Islands under current climatic conditions. This distribution model for C. lukuohia was generated using maxent using methods described in Fortini et. al 2019 (Forest Ecology and Management).

Our analysis compares the environmental range of C. lukuohia and its spread over time through the known climatic range and distribution of ʹōhiʹa. This data set is a georeferenced raster file, containing the projected suitability for C.lukuohia across the main Hawaiian Islands using climatic variables that varied consistently with C. lukuohia prevalence (Mean annual precipication and minimum temperature of coldest month) at 500 meter resolution. This C. lukuohia habitat suitability was generated using maxent using methods described in Fortini et. al 2019 (Forest Ecology and Management).

Our analysis compares the environmental range of C. lukuohia and its spread over time through the known climatic range and distribution of ʹōhiʹa. This data set is a georeferenced raster file, containing the projected potential presence of C.lukuohia across the main Hawaiian Islands using climatic variables that varied consistently with C. lukuohia prevalence (Mean annual precipication and minimum temperature of coldest month) at 500 meter resolution. This modeled C. lukuohia potential presence was generated using maxent using methods described in Fortini et. al 2019 (Forest Ecology and Management).

This data release includes data and metadata containing (1) study site locations and elevation where bolts (tree stem sections) infected with Ceratocystis lukuohia and/or C. huliohia were collected on Hawai'i Island, (2) the ambrosia beetle (Coleoptera: Scolytinae) species that were reared from bolts, (3) Ceratocystis spp. viability results from culturing tests of the beetles' frass, (4) frass production estimates from three ambrosia beetle species, and (5) quantitative Polymerase Chain Reaction (qPCR) DNA results of viability subcultures. Data were used in the analysis for the manuscript "Ambrosia beetle communities and frass production in ʻōhiʻa (Metrosideros polymorpha) infected with Ceratocystis fungi responsible for Rapid ʻŌhiʻa Death." Beetles and frass were collected in the lab from Rapid 'Ōhiʻa Death-infected trees from 2018-2019.
