Biology and Ecosystems
Learn more about research and monitoring on freshwater, terrestrial, and marine ecosystems and the fish and wildlife within them. Healthy ecosystems provide our society with essential ecosystem services, such as crop pollination, water and air purification, harvestable populations of fish and wildlife, soil replenishment, pest control, and nutrient cycling.
Random Landscape Tool uses a raster data source and a table of classifications to create a random landscape. The classification table allows the user to weight the probability of occurrence to certain classes and to spatially restrict the distribution of classes to certain areas (zones).
There are ongoing needs for analytical tools to investigate the cumulative effects of fluctuating water flow and depth. The Connectivity and Inundation Tool was developed at UMESC to help address these needs.
- A revised toolset, entitled "Management Unit Prioritization Tools", consisting of two separate tools; the Conservation Objective Prioritization Tool and the Overall Prioritization Tool were developed.
- The development of these decision support tools give resource managers the ability to make thoughtful and strategic choices about where to spend their limited management resources.
Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine
In this study, we examined habitat fragmentation consequences owing to a planned 1,295 hectare development by Winter Harbor Holding Company (WHHC) adjacent to the Schoodic District of Acadia National Park (ANP), Maine.
Curve Fit is an ArcMap 10.1 (10.2 forthcoming) tool that:
- performs pixel level regression analysis on a series of raster datasets
- is capable of calculating both linear and nonlinear regressions
- allows the user to constrain parameters for nonlinear models
- generates raster surfaces representing parameter estimate, model fit, and multi-model inference
The Percent Edge Tool is an ArcMap tool. The Percent Edge Tool performs the following calculations for each polygon in a polygonal GIS layer: area, compactness, perimeter, edge lengths with adjacent polygons, and percentage of edge with adjacent polygons. This information can then be summarized into a pivot table and queried.
Where are most important places to direct conservation effort? Such a simple question is not answered simply. There are a myriad of priorities, constraints, and capacities, both scientific and socio-economic, which in combination guide the allocation of management effort. An honest accounting of these priorities, constraints, and capacities is essential for efficient, effective action.
- Allows managers and planners to rapidly assess landscape attributes and link these attributes with species/habitat information
- Provides resource managers a means to compare the conservation potential of local management units with that of the surrounding county, state, or region
- Can be applied to any taxa or suite of taxa and any landscape, given that spatial data.
- The Split By Attribute Tool is a customization of ArcMap.
- The tool takes a single shapefile and splits it into many shapefiles based on the unique values of a chosen field.
- If the user has made a selection on a shapefile, then only those features that have been selected will be split.
- Each output layer will named with the following structure: user supplied base name + split value.
- The Census Stop Tool is a GIS tool that creates random points along a line layer while maintaining a minimum distance between points.
- The user has the option of selecting one of two random point placement methods.
- The Census Stop Tool is available as an ArcMap 9.x extension.
- This tool is designed to facilitate road based surveys by reducing the potential for double sampling.
- The Adjacency For WinBUGS Tool is a customization of ArcMap.
- The tool iteratively processes each polygon within a selected layer and creates a text file of polygonal adjacency where each polygon is identified by a unique Adj_ID value.
- The output of this tool is used in WinBUGS (MRC Biostatistics Unit Cambridge) by the car.normal, car.l1, and mv.car conditional autoregressive distributions.
The Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has collected millions of records of information over 20+ years. Fisheries, water quality, vegetation, and invertebrates have all been sampled. Geographic locations were collected for all sampling points.
