We investigated the use of nesting resources in a landbird community arid zone near Peery Lake, northwestern New South Wales. Over 3.5-year period (1990–1994), which encompassed pre-drought, drought and post-drought conditions, we recorded 504 active nests 51 breeding species, including open- (45% all species), hollow- (27%), mud- (8%), ground- (8%) tunnel-nesters (4%), species that nested both...
Global climate underwent a major reorganization when the Antarctic ice sheet expanded ~14 million years ago (Ma) (1). This event affected global atmospheric circulation, including the strength and position of the westerlies and the Intertropical Convergence Zone (ITCZ), and, therefore, precipitation patterns (2-5). We present new shallow-marine sediment records from the continental shelf of Aus...

For this reason, a more suitable foundation type should be selected designed built on these soils. example, application belled shaft at expansive soil layer is preferable method practice. However, one worst cases design accepted sw...
The commercial exploitation of guinea fowl (Numidia meleagris) is a viable alternative for small rural properties in arid and semi-arid regions, as they are rustic birds capable withstanding the climatic adversities these regions. objective this study was to evaluate pupillary temperature, smaller diameter, larger diameter pupil area housed controlled environment, under two air temperatures: 26...
