A suite of 42 morphometric parameters for each of 26 272 drainage basins larger than 100 km2 from the Hydrosheds Shuttle Radar Topography digital elevation model shows the global distribution of Strahler order for streams and drainage basins. At the scale of 15 arc s spacing (232 to 464 m) the largest basins are order 9. Many common parameters depend both on the size of the basin, and the scale...

Plant can alter reproductive strategies for adaptation to different environments. However, alterations in flowering strategies and sexual allocation for the same species growing in different environments still remain unclear. We examined the sexual reproduction parameters of Caragana stenophylla across four climatic zones from semi-arid, arid, very arid, to intensively arid zones in the Inner M...

We investigated hourly time-series of total dissolved solids (TDS) in the Okavango River at inlet and outlet Delta (Delta) semi-arid Botswana. estimated solute flux into out Delta. Our objectives were to (1) document temporal variations solutes (represented by TDS) determine processes that control concentrations (2) quantify load The varied from sub-weekly monthly time frames, with a semi-annua...

Foreword The CRC for Catchment Hydrology S2 project 'Managing Disposal Basins for Salt Storage within Irrigation Areas' was based on the premise that disposal basins are 'a fact of life' in the Murray-Darling Basin. Consequently there is a need for guidelines to site, design and manage them to minimise environmental and other problems. However, more than 190 existing basins were built when ther...

[1] We compare morphologies of drainage basins on Mars and Earth in order to confine the formation process ofMartian valley networks. Basins on both planets are computationally extracted from digital topography. Integral-geometry methods are used to represent each basin by a circularity function that encapsulates its internal structure. The shape of such a function is an indicator of the style ...

ARID (AT-rich interaction domain) is a homologous family of DNA-binding domains that occur in DNA-binding proteins from a wide variety of species, ranging from yeast to nematodes, insects, mammals, and plants. SWI1, a member of the SWI/SNF protein complex that is involved in chromatin remodeling during transcription, contains the ARID motif. The ARID domain of human SWI1 (also known as p270) do...

Using data collected from six basins located across two hydrologically contrasting agricultural catchments, this study investigated whether transport metrics alone provide better estimates of storm phosphorus (P) loss from basins than critical source area (CSA) metrics which combine source factors as well. Concentrations and loads of P in quickflow (QF) were measured at basin outlets during fou...
