Determining the water balance of a landscape is important to sustainable management of water, vegetation and land resources. Water flow through vegetation is the principle pathway for the discharge of water from Australian ...

As oyster fishing continues to degrade reef habitat along the US Atlantic coast, oyster reefs appear increasingly fragmented on small spatial scales. In outdoor mesocosms, experiments tested how consumption of representatives ...

Single-vein leaves have the simplest hydraulic design possible, yet even this linear water delivery system can be modulated to improve physiological performance. We determined the optimal distribution of transport capacity ...

The influence of biodegradable chelating ligands on arsenic and iron uptake by hydroponically grown rice seedlings (Oryza sativa L.) was investigated. Even though the growth solution contained sufficient Fe, the growth of ...

Many lipoproteins are expressed on the surfaces of mycoplasmas, and some have been implicated as playing roles in pathogenesis. Family 2 lipoproteins of Mycoplasma plleumoniae have a conserved "mycoplasma liM poprotein X" ...

Arginine metabolism is an important source of energy and nitrogen in matly microbes. In this report, we present the sequence and activity of a novel microbial enzyme located in certain arginine-handling operons. The enzyme ...

We used transparent planar oxygen optodes and a luminescence lifetime imaging system to map (at a pixel resolution of <200 ?m) the two-dimensional distribution of O₂ within the skeleton of a Porites lobata colony. ...
