The famous theoretical biologist Hans Meinhardt died on 11 February 2016 in Tübingen. Meinhardt is well known for mathematical models of biological pattern formation, which he applied to a wide range of problems in developmental biology such as body axis formation, segmentation, limb patterning, regeneration, phyllotaxis and surface patterns — most famously the color patterns on seashells. Hans...

Todetermine useful metrics for assessing streamwater quality in the Southeastern Coastal Plain, we examined differences among two buffered and three unbuffered streams in an agricultural landscape in southwestern Georgia. Potential indicators included amphibian diversity and abundance, aquatic macroinvertebrate populations, riparian vegetative structure, water quality, and stream physical param...

of the nitrogen cycling has major consequences for other biogeochemical processes and ecosystem functions and services, Voss says. Recent research has uncovered an apparent imbalance in the nitrogen budget of the oceans, which isn’t completely understood yet and may point to additional processes that remain to be discovered. The traditional view that bacterial denitrification is the only signif...
