The roles of competition and habitat in the dynamics of populations and species distributions
Charles Brandon Yackulic, Janice Reid, James D. Nichols, James E. Hines, Raymond Davis, Eric Forsman
2014, Ecology (95) 265-279
The role of competition in structuring biotic communities at fine spatial scales is well known from detailed process-based studies. Our understanding of competition's importance at broader scales is less resolved and mainly based on static species distribution maps. Here, we bridge this gap by examining the joint occupancy dynamics of...

Li Zhang, Huadong Guo, Gensuo Jia, Bruce Wylie, Tagir Gilmanov, Daniel M. Howard, Lei Ji, Jingfeng Xiao, Jing Li, Wenping Yuan, Tianbao Zhao, Shiping Chen, Guangsheng Zhou, Tomomichi Kato
2014, Agricultural and Forest Meteorology (184) 71-81
Grassland is one of the widespread biome types globally, and plays an important role in the terrestrial carbon cycle. We examined net ecosystem production (NEP) for the temperate grasslands in northern China from 2000 to 2010. We combined flux observations, satellite data, and climate data to develop a piecewise regression...
Relative significance of microtopography and vegetation as controls on surface water flow on a low-gradient floodplain
Jungyill Choi, Judson W. Harvey
2014, Wetlands (34) 101-115
Surface water flow controls water velocities, water depths, and residence times, and influences sediment and nutrient transport and other ecological processes in shallow aquatic systems. Flow through wetlands is substantially influenced by drag on vegetation stems but is also affected by microtopography. Our goal was to use microtopography data directly...

Edward R. Schenk, Bertrand Moulin, Cliff R. Hupp, Jean M. Richte
2014, Earth Surface Processes and Landforms (39) 487-498
Despite the abundance of large wood (LW) river studies there is still a lack of understanding of LW transport dynamics on large low gradient rivers. This study used 290 radio frequency identification tagged (RFID) LW and 54 metal (aluminum) tagged LW, to quantify the percent of in-channel LW that moves...

An application of Social Values for Ecosystem Services (SolVES) to three national forests in Colorado and Wyoming
Benson C. Sherrouse, Darius J. Semmens, Jessica M. Clement
2014, Ecological Indicators (36) 68-79
Despite widespread recognition that social-value information is needed to inform stakeholders and decision makers regarding trade-offs in environmental management, it too often remains absent from ecosystem service assessments. Although quantitative indicators of social values need to be explicitly accounted for in the decision-making process, they need not be monetary. Ongoing...

Brian Weidel, Michael J. Connerton
2014, NYSDEC Lake Ontario Annual Report 2013-12
Rainbow Smelt Osmerus mordax are the second most abundant pelagic prey fish in Lake Ontario after Alewife Alosa psuedoharengus. The 2013, USGS/NYSDEC bottom trawl assessment indicated the abundance of Lake Ontario age-1 and older Rainbow Smelt decreased by 69% relative to 2012. Length frequency-based age analysis indicated that age-1 Rainbow...

Charles A. Cravotta III,, Daniel J. Goode, Michael D. Bartles, Dennis W. Risser, Daniel G. Galeone
2014, Hydrological Processes (28) 3574-3601
Streams crossing underground coal mines may lose flow, while abandoned mine drainage (AMD) restores flow downstream. During 2005-12, discharge from the Pine Knot Mine Tunnel, the largest AMD source in the upper Schuylkill River Basin, had near-neutral pH and elevated concentrations of iron, manganese, and sulfate. Discharge from the tunnel...

Chapter A7. Section 7.1. Fecal indicator bacteria
Donna N. Myers, Marc A. Sylvester
2014, Techniques of Water-Resources Investigations 09-A7.1
Fecal indicator bacteria are used to assess the microbiological quality of water because, although not typically disease causing, they are correlated with the presence of several waterborne disease-causing organisms. The concentration of indicator bacteria is a measure of water safety for body-contact recreation or for consumption. This report provides information...

A one-dimensional diffusion analogy model for estimation of tide heights in selected tidal marshes in Connecticut
David M. Bjerklie, Kevin O’Brien, Ron Rozsa
2013, Scientific Investigations Report 2013-5076
A one-dimensional diffusion analogy model for estimating tide heights in coastal marshes was developed and calibrated by using data from previous tidal-marsh studies. The method is simpler to use than other one- and two-dimensional hydrodynamic models because it does not require marsh depth and tidal prism information; however, the one-dimensional...
