Sousa AG1, Harris D1.
The Journal of the Acoustical Society of America.J Acoust Soc Am.2015 Sep;138(3):1379-88. doi: 10.1121/1.4928719.
Unidentified acoustic signals are recorded by hydrophones placed in the world's oceans. Some of these sounds are suspected to originate from marine mammals. In this study, two acoustic signals recorded by two arrays at Diego Garcia in the northern Indian Ocean are described. Data were available betw

Movements and habitat use of an endangered snake, Hoplocephalus bungaroides (Elapidae): implications for conservation.

Croak BM1, Crowther MS, Webb JK, Shine R.
PloS one.PLoS One.2013 Apr 22;8(4):e61711. doi: 10.1371/journal.pone.0061711. Print 2013.
A detailed understanding of how extensively animals move through the landscape, and the habitat features upon which they rely, can identify conservation priorities and thus inform management planning. For many endangered species, information on habitat use either is sparse, or is based upon studies

Phylogeography and dispersal in the velvet gecko (Oedura lesueurii), and potential implications for conservation of an endangered snake (Hoplocephalus bungaroides).

Dubey S1, Croak B, Pike D, Webb J, Shine R.
BMC evolutionary biology.BMC Evol Biol.2012 May 14;12:67. doi: 10.1186/1471-2148-12-67.
BACKGROUND: To conserve critically endangered predators, we also need to conserve the prey species upon which they depend. Velvet geckos (Oedura lesueurii) are a primary prey for the endangered broad-headed snake (Hoplocephalus bungaroides), which is restricted to sandstone habitats in southeastern

Habitat selection in a rocky landscape: experimentally decoupling the influence of retreat site attributes from that of landscape features.

Croak BM1, Pike DA, Webb JK, Shine R.
PloS one.PLoS One.2012;7(6):e37982. doi: 10.1371/journal.pone.0037982. Epub 2012 Jun 12.
Organisms selecting retreat sites may evaluate not only the quality of the specific shelter, but also the proximity of that site to resources in the surrounding area. Distinguishing between habitat selection at these two spatial scales is complicated by co-variation among microhabitat factors (i.e.,
