Jason Rohweder
I have interdisciplinary expertise in biology, geographical information systems (GIS) and application programming. My work emphasizes landscape ecology and the creation of flexible tools and models to assess species habitat.

Application of Wind Fetch and Wave Models for Habitat Rehabilitation and Enhancement Projects Application of Wind Fetch and Wave Models for Habitat Rehabilitation and Enhancement Projects
Models based upon coastal engineering equations have been developed to quantify wind fetch length and several physical wave characteristics including significant height, length, peak period, maximum orbital velocity, and shear stress. These models were used to quantify differences in proposed island construction designs for three Habitat Rehabilitation and Enhancement Projects (HREPs) in...

Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine
Most national parks interact with adjacent lands because their boundaries fail to encompass all regional habitats, species pools, and migration routes. Activities planned for adjacent lands can have adverse effects on park resources and visitor experiences. For example, fragmentation of adjacent habitat into smaller and more isolated remnants may influence the suitability of park habitat...

Exploring relationships among land ownership, agricultural land use, and native fish species richness in the Upper Mississippi River Basin Exploring relationships among land ownership, agricultural land use, and native fish species richness in the Upper Mississippi River Basin
The general effects of agriculture on in-stream fish communities in the Upper Midwestern United States have been well studied for nearly three decades (Karr et al. 1985; Nerbonne and Vondracek 1991; Zimmerman et al. 2001; Goldstein and Meador 2005). Specific impacts include: lowered water levels, sediment loading and nutrient enrichment, loss of riparian habitat, changes to channel...

Spatial scaling of core and dominant forest cover in the Upper Mississippi and Illinois River floodplains, USA Spatial scaling of core and dominant forest cover in the Upper Mississippi and Illinois River floodplains, USA
Different organisms respond to spatial structure in different terms and across different spatial scales. As a consequence, efforts to reverse habitat loss and fragmentation through strategic habitat restoration ought to account for the different habitat density and scale requirements of various taxonomic groups. Here, we estimated the local density of floodplain forest surrounding each...

Spatial patterns of aquatic habitat richness in the Upper Mississippi River floodplain, USA Spatial patterns of aquatic habitat richness in the Upper Mississippi River floodplain, USA
Interactions among hydrology and geomorphology create shifting mosaics of aquatic habitat patches in large river floodplains (e.g., main and side channels, floodplain lakes, and shallow backwater areas) and the connectivity among these habitat patches underpins high levels of biotic diversity and productivity. However, the diversity and connectivity among the habitats of most floodplain...
