ABSTRACT Combined drainage/fauna culverts and dedicated fauna underpasses are routinely used to mitigate the potential barrier effects of roads and reduce road-related mortality. To determine the success of underpasses constructed as part the Pacific Highway Upgrade in eastern NSW automated cameras were used to monitor a number of underpasses. The first monitoring period (autumn 2018) recorded photographic evidence of a Spotted-tailed Quoll Dasyurus maculatus using a combined underpass on day 61 of a 63-night monitoring period. To our knowledge, this is the first photographic evidence of use of an underpass by a D. maculatus in NSW and supports the installation of box culverts as a mitigation measure to facilitate movement for this species.

New Pb I absorption spectra show discrete structure due to excitation of the 4f subshell and continuous absorption beyond the 4f thresholds. The results are compared with those previously obtained in Tl I and Hg I, and the presence of additional maxima in the Pb I spectrum is accounted for by comparison with recent independent-particle non-relativistic central field calculations.
