Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2020 (ver. 7.0, June 2022) We tested the utility of a protocol using genetic markers that previously proved successful to identify the sex of Vespertilionid bats on tissues collected from live bats and carcasses of varying age from the Hawaiian hoary bat (Lasiurus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North American hoary bats (L. cinereus). Using genotyping, we determined the sex of 123 of 125 Hawaiian hoary bat tissue samples from carcasses. This dataset includes all 73 samples from the original data release, plus 58 additional samples. NOTE: While previous versions are available from the author, all the records in previous versions can be found...

The data release also includes information documenting sensitivity, specificity, and accuracy of quantitative polymerase chain reaction (qPCR) assays to detect environmental DNA (eDNA) from tilapia (Oreochromis mosambicus), western mosquitofish (Gambusia affinis) and guppies (Poecilia reticulata). In total there are 11 datasets, 9 describing lab trials and 2 describing field trials. Lab data include 1) initial water conditions during pilot study, 2) behavioral response of fish to CO2 during pilot study, 3) survival...

Specifically, water infiltration measurements, interepreted field-saturated hydraulic conductivity values, ungulate activity, vegetation cover, general soil and weather conditions data are included. Soil samples were collected, lab analyzed, and are included in the dataset. Field-collected data are associated with plots that encompassed approximately a 3 x 3 m area; site data represent approximately 20 x 20 m. First posted: 4 March 2020 (available from author) Revised: April 13, 2020 (version 2.0) The revision is provided due to minor refinement of the dataset and updated...

The protocol uses cue rates from the target species as well as sampling conditions and an estimate of the distance of the individual to the recorder based on the power of the sound. We applied our protocol to estimate the density of two Hawaiian forest bird species (Hawaiˊi ˊamakihi, Chlorodrepanis virens and ˊōmaˊo, Myadestes obscurus) on the island of Hawaiˊi, USA. We validate our approach by comparing our density estimations with others calculated at the same stations using a traditional point-transect distance sampling...
