Koa looper moth caterpillars on Koa leaves

Dynamics of a Koa Looper Moth Outbreak and Response by the Native Forest Community

A massive outbreak of the native koa looper moth (Scotorythra paludicola; Geometridae) defoliated more than a third of the koa (Acacia koa) forest on Hawai‘i Island during 2013–2014. Our objective was to record the dynamics of the koa looper (Scotorythra paludicola) outbreak and evaluate the response to the outbreak by the forest ecosystem generally as well as select native and invasive species...

Hakalau litter, frass, soil, and understory foliar nitrogen during a koa moth outbreak, 2013-2014 Hakalau litter, frass, soil, and understory foliar nitrogen during a koa moth outbreak, 2013-2014

This data release includes metadata and tabular data that document estimates of litterfall, koa moth (Scotorythra paludicola) caterpillar frass production, soil nutrients, and foliar nutrients during 2013-2014 at Hakalau Forest National Wildlife Refuge. During this time, there was a massive defoliation event of Acacia koa (koa) trees by the koa moth. We monitored these metrics in 4 sites...

Climatic drought and trophic disruption in an endemic subalpine Hawaiian forest bird Climatic drought and trophic disruption in an endemic subalpine Hawaiian forest bird

Overexploitation, habitat conversion, and introduced species have caused unprecedented extinctions and heavily degraded native bird populations in island ecosystems. In the Hawaiian Islands, stemming these losses has proven difficult as the highly specialized avifauna are often impacted – among other things – by poorly understood trophic disruptions as well as persistent climatic shifts...

Reproductive ecology and egg parasitism of the Samoan swallowtail butterfly Reproductive ecology and egg parasitism of the Samoan swallowtail butterfly

We investigated the reproductive ecology and effects of egg parasitism on the Samoan swallowtail butterfly (Papilio godeffroyi), which survives only on Tutuila Island, American Samoa, after having disappeared from the much larger islands of Upolu and Savai‘i in independent Samoa. During monthly surveys of its only known host plant, Micromelum minutum, across eight sites in 2013 and 2014...

Nihoa and Laysan Island passerines population abundances, trends, and habitat utilization Nihoa and Laysan Island passerines population abundances, trends, and habitat utilization

Nihoa and Laysan Island, part of the Northwestern Hawaiian Islands, are host to three endangered passerine species—Nihoa finch (Telespiza ultima), Nihoa millerbird (Acrocephalus familiaris kingi), and Laysan finch (Telespiza cantans). Using point-transect distance sampling survey records from 2010 to 2022 for Nihoa and 2013 to 2019 for Laysan Island, we estimated the density and...

Carbon dioxide (CO2) gas and eDNA monitoring as tools for eradicating invasive fish from anchialine pools in Hawai‘i Carbon dioxide (CO2) gas and eDNA monitoring as tools for eradicating invasive fish from anchialine pools in Hawai‘i

Invasive fish can profoundly affect communities they invade. In Hawai‘i, invasive fishes have become established in many anchialine pools, threatening the persistence of resident invertebrates, including several endangered species. Tools to eradicate invasive fishes from these pools are lacking. This study tested the efficacy of carbon dioxide (CO2) gas diffused into anchialine pool...

Twenty-five years of change in forest structure and nesting behavior of Hawaiʻi ʻelepaio Twenty-five years of change in forest structure and nesting behavior of Hawaiʻi ʻelepaio

Long-term ecological studies are invaluable for detecting changes over time. Forest restoration has been a conservation priority in Hawaiʻi, where invasive species have negatively impacted native bird habitat. During 1993–1994, a study was conducted of Hawaiʻi ʻelepaio (Chasiempis sandwichensis) nest site selection and forest composition in mesic montane forest along Mauna Loa Road in...

Evaluation of replicate sampling using hierarchical spatial modeling of population surveys accounting for imperfect detectability Evaluation of replicate sampling using hierarchical spatial modeling of population surveys accounting for imperfect detectability

Effective species management and conservation benefit from knowledge of species distribution and status. Surveys to obtain that information often involve replicate sampling, which increases survey effort and costs. We simultaneously modeled species distribution, abundance and spatial correlation, and compared the uncertainty in replicate abundance estimates of the endangered palila...
