Slide 3

What is Home Range? The depiction of a creatures space utilize The home extent is accepted to contain the fundamental prerequisites, for example, sustenance, water and cover Wildlife Techniques Manual

Slide 4

Home reach qualities Home ranges frequently cover (instead of domains) Home reach size has been corresponded to body size Can clarify a creatures natural examples Can enhance comprehension of biological connections

Slide 5

Telemetry information or GPS neckline Tabular information in Excel (2003) .dbf or .txt arrangement can be straightforwardly foreign to ArcGIS or ArcView

Slide 7

Home Range Methods Minimum Convex Polygon Harmonic Mean Kernal Jennrich-Turner

Slide 8

Minimum Convex Polygon Minimum Convex Polygon (MCP) is characterized as the polygon drawn around the peripheral focuses

Slide 9

Fixed portion home reach is as of now suggested Contours The measure of the bit home reach is touchy to the transfer speed esteem (h) utilized!

Slide 10

Kernel Density Functions n – number of areas h – smoothing parameter d – separation from the area x, y

Slide 11

… .a couple of suspicions Locations are autonomous sufficiently large example size Smoothing parameter (piece estimators)

Slide 12

Bandwidth, h-component, smoothing parameter Least Squares Cross Validation (LSCV) Currently prescribed Tendency to undersmooth, makes various nearby minima High variability Likelihood Cross Validation (CV) Novel strategy (Horne and Garton 2006) Performs better for littler specimen sizes (< 50) Better fit and less variability Normal or Reference technique (h ref ) Scaled-REF (h ref is increased by a settled extent) Gitzen et al. 2006 Horne and Garton 2006

Slide 18

Animal Movement Extension Will use any kind of point information that can be gotten into ArcView Works any projection* Works on any chose subset of data* Produces Coverages, Grids, or Tables i.e. all yield is good with ArcView *Except G in = G out 2 G = Garbage U.S. Division of Interior U.S. Land Survey Alaska Biological Science Center Glacier Bay Field Station
