Data from: Large-scale bioacoustic monitoring to elucidate the distribution of a non-native katydid

For animals that produce species-specific audible sounds, environmental
recordings combined with automated acoustic monitoring software (passive
acoustic monitoring, PAM) may be an effective monitoring tool because it
allows audio data from many, widely distributed autonomous recording units
(ARUs) to be processed in a relatively short period of time. Males of many
insect species produce loud, species-specific mating songs, yet acoustic
insects have received less attention from PAM relative to vertebrates. We
evaluated the use of PAM to monitor, Roeseliana roeselii
(Orthoptera, Tettigoniidae), an acoustic insect that has expanded its
range to Alberta, Canada far outside its naturalized North American range.
We analyzed environmental recordings from ARUs: 1) at two control sites
known to be occupied by R. roeselii, and 2) across Alberta established by
the Alberta Biodiversity Monitoring Institute (ABMI) to search for new
populations. PAM successfully detected R. roeselii at the two
control sites, but not at any of the 74 ABMI sites that we analyzed.
Despite the failure to detect new locations of R. roeselii, our analysis
of ABMI environmental recordings detected several other species of
acoustic insects, including Orchelimum gladiator, Gryllus sp. and
Allonemobius spp. Our results add to the growing body of work showing the
feasibility of using PAM for acoustic insects. We make suggestions for how
to maximize the effectiveness of this monitoring tool for the conservation
and management of singing insects in North America.
