Minutes of 2006 NC 1005 Meeting - page 8 / 9





8 / 9

ILLINOIS:  (Eric) 2002 began work near Carbondale.  Look at deer behavior in exurban environment.  Looked at behavior relative to buildings and roads – surveyed land owners about perspectives on deer.   GPS collars (n=29) will drop off in March.  2 males and 27 females.  One male only 2 weeks.  Does 3-16 months – 2 hr intervals.  Telonix GPS units- excellent luck.  2 drop off mechanisms failed.   2500 – 10000 relocations per animal.

Dan Storm’s work – habitat use – found deer avoided dwellings during fawning season less so during other seasons.  Deer used linear strip so f developed areas with edge associated with them.  HD data suggest that landowners are generally not farming. Bedroom communities. Positive about deer even though they experienced damage to plantings.  Pl concerned about deer control were concerned about collisions.   Lower hunting pressure – 1-2 pl on properties to hunt.  90% does survival.  VHF data on 17 does – fawning and winter locations.  50 relocations for each season.  Fawn survival data in Poke and Johnson Counties – 2003.  48, 52 56 fawns over 3 years.  No differences in survival – 54% survival.  Mortality due to coyote predation.  

John Romme’s MS thesis.  Landscape analysis related to fawn survival.  Size of forest patches and edge density related.  Manuscripts in process.  Small home ranges- 100 km2.  Used animal extension of Arcview – need to go back review calculations.

Eric’s work is an extension of Al Wolf’s work – looking at contact rates – direct and indirect contacts- how often do they come into close contact with each other?  How often do they come into contact with same site within 1-3 days of each other.  Does it matter whether deer are in same social group?  Found you could define groups based on hr overlap.  Odds ratio 22 times higher that they would come into direct contact if in same group.  Indirect contacts – 1 day lag- group membership disappeared – hr overlap explained everything.  In revision right now- Next paper is asking when and where contacts are happening.  Lina Kjare will be creating model to look at random walk patterns and probabilities of contact.  Looking at bait piles and interactions.  Finding peaks and trough with full and new moons.  Diel cycles in movements.

New work- capture in central IL- corn dominated landscape.  Contact rates, seasonal habitat distributions, harvest vulnerability, movements, by habitat composition and type.  

Data Sharing ideas:  Data from each site will be a single data point- regional publications would not be included on authorship and their data would not be double published.  Are there other data sets to get hold of for a meta-pop analysis.
