supercell thunderstorm across Great Plains
2019/11/22
The most ambitious drone-based investigation of severe thunderstorms to date will soon be launched by atmospheric scientists at the University of Nebraska-Lincoln and three partner institutions: Texas...
A NEW SPECIES OF MOROPUS (MAMMALIA, PERISSODACTYLA, CHALICOTHERIODEA) IN THE BATESLAND FORMATION, GREAT PLAINS AREA OF NORTH AMERICA
Great Plains Batesland Formation Miocene
2015/1/4
The chalicothere Moropus was a rare perissodactyl present in the Great Plains region of North America through much of the Miocene. A temporal gap in named species of Moropus is present in the early He...
Magnitudes and controls of organic and inorganic carbon flux through a chain of hard-water lakes on the northern Great Plains
Magnitudes and controls of organic inorganic carbon flux through hard-water lakes northern Great Plains
2014/4/17
Whole-lake carbon (C) mass-balance budgets were constructed for a chain of six hard-water lakes to quantify the relative importance of organic carbon (OC) and inorganic carbon (IC) exchanges between a...
Experimental evidence that pollution with urea can degrade water quality in phosphorus-rich lakes of the Northern Great Plains
pollution urea degrade water quality phosphorus-rich lakes the Northern Great Plains
2014/4/17
Urea is the most abundant nitrogen (N) fertilizer used on agricultural soils, yet its effects on adjacent aquatic ecosystems are largely unknown. Here 21-d, 3000-liter mesocosm experiments were conduc...
Regulation of spatial and temporal variability of carbon flux in six hard-water lakes of the northern Great Plains
Regulation of spatial temporal variability carbon flux six hard-water lakes northern Great Plains
2014/4/17
Six hard-water lakes were sampled May-August for 14 yr in a 52,000 km2 catchment to identify the mechanisms that regulate the spatial and temporal variability of net atmospheric exchange of CO2 of lak...
Spatial variability of climate and land-use effects on lakes of the northern Great Plains
Spatial variability climate land-use on lakes of the northern Great Plains
2014/4/21
Evaluation of the effects of climate change and human activities on lakes requires improved understanding of how stressors interact and the degree to which individual sentinel lakes represent broad sp...
Spatial variation of nitrogen fixation in lakes of the northern Great Plains
Spatial variation nitrogen fixation the northern Great Plains
2014/5/4
Cyanobacterial blooms are a regular feature of lakes in central North America, but little is known of their importance to the nitrogen (N) cycle and nutrition of aquatic food webs. We hypothesized tha...
