Insecticide Beetle Gallery Count Data

These data contain the number of beetle attacks on the cut surface ʻōhiʻa bolts that were either treated with Bifen IT insecticide (Bifenthrin 7.9%) or left untreated.

Hawaiʻi Island Rapid ʻŌhiʻa Death Decontamination 2019-2020

Rapid ʻŌhiʻa Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawaiʻiʻs keystone trees species, ʻōhiʻa (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fi

Viable Ceratocystis Propagules in Frass

These data include Ceratocystis culture viability results from ambrosia beetle (Coleopetera: Scolytinae) frass. Frass is defined as fine particles of macerated wood or boring dust, beetle parts, and feces. Frass was collected from individual ambrosia beetle galleries in Ceratocystis-infected ʻōhiʻa (Metrosideros polymorpha) trees on Hawaiʻi Island, a phenomenon

Subculture qPCR DNA Results

These data include the quantitative Polymerase Chain Reaction (qPCR) Ceratocystis lukuohia and C. huliohia DNA confirmations of viable subcultures. These data were used to determine the accuracy of morphological identifications.

Rapid ʻŌhiʻa Death Ambrosia Beetles

These data include the ambrosia beetle (Coleoptera: Scolytinae) species that were reared from bolts (tree stem sections) infected with Rapid ʻŌhiʻa Death on Hawaiʻi Island from 2018-2019. These data were used to determine species, number of individuals reared, height, and elevation in which these beetles live.

Beetle Frass Production

These data include frass production estimates from three ambrosia beetle species. Frass was collected from individual ambrosia beetle galleries in Rapid 'Ōhiʻa Death-infected ʻōhiʻa trees (Metrosideros polymorpha) from 2018-2019. Frass is defined as fine particles of macerated wood or boring dust, beetle parts, and feces.

Hawaii Volcanoes National Park stable isotope values from Hawaii forest birds 2012

Blood and feathers were collected from Hawaii forest birds (Apapane and Hawaii Amakihi) in high elevation forest to assess evidence for altitudinal movement. Feathers, red blood cells and plasma were analyzed for hydrogen, carbon, and nitrogen stable isotope ratios, and these were used to infer changes in elevation and diet over time. For each species, at one of 3 sites, isotope v

Seedling Mortality of Ohia by Treatment Group at Keaukaha Military Reserve 2019-2020

This data release includes monthly census data of 120 out-planted ohia seedlings in different treatment groups and associated metadata from February 2019 - February 2020 at Keaukaha Military Reservation in Hilo, HI. Six seedlings each were planted around 20 focal trees, half of which tested positive for Rapid Ohia Death, half of which tested negative. Three of the six seedlings were weeded
