Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2019 (ver. 3.0, Nov 2019)

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 cinereus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North American ho...

Modeled potential presence of Ceratocystis luhuohia across Hawaiian Islands

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
