We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lāupahoehoe Forest Reserve on Hawai‘i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level that operated nightly from May 2013 through September 2013. We compared these data to data collected at similar locations during 2007-2011 to determine the response of bats to increased moth abundance during 2013. In this abstract we refer to the Hawaiian hoary bat as a full species, Lasiurus semotus, following updated taxonomy for Hawaiian hoary...

This data release consists of a single table that includes sample site geographic locations, insect prey abundance, and bat activity and behavior metrics. The dataset was used to develop multi-state occupancy models of foraging habitat use by Hawaiian hoary bats (Lasiurus cinereus semotus).

Hawaiian hoary bat insect prey sampling with paired acoustic monitoring was conducted at Keaukaha Military Reservation (KMR) on Hawaii Island from May to August, 2018. At this property, a herd of domestic goats (occasionally mixed with domestic sheep) were rotated among grazing plots as part of a weed control program managed by Hawaii Army National Guard (HIARNG). We sampled insect abundance and community within the area where goats were used for weed control to better understand if grazing ungulates attract and support potential prey for insectivorous Hawaiian hoary bats.

Genetic diversity levels, effective population size estimates, and population structure of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) were examined across the islands of Hawai‘i, Maui, O‘ahu, and Kaua‘i using eighteen nuclear microsatellite loci and one mitochondrial gene from 339 individuals collected between 1988 and 2020. The study extracted DNA for population genetic analyses from tissue samples, collected from live bats captured as part of ongoing field studies or under rehabilitation care, from bat carcasses collected by local federal and state wildlife agencies and wind energy facilities, and from dried skin specimens at the Bernice Pauahi Bishop Museum. Eighteen...

Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae), was examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. Research funding to study bat ecology was provided by Auwahi Wind Energy, LLC in order to fulfill requirements for mitigating bat fatalities under it's approved incidental take permit. This study included the first genetic analysis of Hawaiian hoary bat diet items, and broadly confirms the major arthropod orders (Coleoptera, Lepidoptera, Diptera, Hemiptera, and Blattodea) found in previous microscopy-based...
