This Concept Map, created with IHMC CmapTools, has information related to: CMap 1 (R.Delis Snake Conservation), examine the composition of snake assemblages among habitats, test earlier findings concerning grassland assemblage dynamics, and provide temporal activity patterns Results/Data Seasonal Activity, Mostly in May, no sig dif between sexes but size differs Males are 4.7% smaller than females, 16 new and 24 total found in two open and permanent ponds, examine the composition of snake assemblages among habitats, test earlier findings concerning grassland assemblage dynamics, and provide temporal activity patterns Conclusion in SW PA, Mostly in June with body size differing if NAR were present; females were smaller when not around NAR; males sig smaller than females, Species Accounts 3rd species Diadophis punctatus or Ring-necked snake, Agkistrodon contortrix or Copperhead amount captured 4 new and 4 total, 3 new and 3 total found in 2 sites near the edge of fields bordering forests, 81 new and 86 total found in 9 sites and in most habitat types, mostly along exposed ponds, 2 sites near the edge of fields bordering forests seasonal activity In June and July, Storeria occipitomaculata or Red-bellied snake amount found only 1 (was pregnant), 20 new and 23 total found in 10 sites, but not common in any, Species Accounts 1st species Agkistrodon contortrix or Copperhead, Species Accounts 7th species Storeria occipitomaculata or Red-bellied snake, In June and July mean body size of males were 1% larger than females; variance had no sig dif, Species Accounts 4th species Lampropeltis triangulum or Milksnake, Diadophis punctatus or Ring-necked snake amount captured 28 new and 29 total, Seasonal Activity Highest number found May-July (73% of all captures), Lampropeltis triangulum or Milksnake amount captured 20 new and 23 total, examine the composition of snake assemblages among habitats, test earlier findings concerning grassland assemblage dynamics, and provide temporal activity patterns Results/Data Assemblage Structure
