  1. Lagomorpha

  2. Order Lagomorpha • Derived from Greek lagos ("hare") and morphē ("form") • 80 species • Two families - Leporidae – Rabbits and hares - Ochotonidae – pikas

  3. Characteristics of Lagomorpha • have 4 incisor on upper jaw (rodents have 2) • only eat vegetation • male's scrotum is in front of the penis • penis has no bone (baculum) unlike the rodent penis • will redigest first-time droppings (called cecotropes) to obtain the most from their plant diet

  4. Ochotonidae • American Pika - Western North America - live in rock piles - size of a large hamster - rounded ears - egg shape body - 6 to 8.5 inches in length - weigh 100grams

  5. Pikas • Herbivore • Active year round, even in winter • It survives the cold winter by eating dried vegetation they have stored away in hay piles • alpine grasses, sedges, thistles, fireweed, cushion plants and lichens • Food passes quickly though the digestive, system only partially digested • eat their own feces (waste) to extract more nutrients in the digestion process. • http://www.youtube.com/watch?v=Tus1FHc7XWU

  6. Eastern Cotton Tail • Mating during Feb. – September • Males mate with more then one female • Females can have 1-7 litters a years with as many as 1- 12 kits. • Average number of litters is 3-4 and average kits are 5 • Kits are weaned at 3 weeks and leave the nest after 7 weeks

  7. Eastern Cotton Tail • Territorial • Nocturnal • When running can jump 15 feet • Runs zigzag when chased • Can run up to 18mph • Preferred habitat: Forests, swamps, thickets, bushes or open areas where it can dig a burrow are optimal habitation sites for this species

  8. Species in Pennsylvania • Three different Lagomorphs in Pa - Eastern Cotton Tail - New England Cotton Tail - Snowshoe Hare

  9. Differences • To determine the difference between Eastern Cottontail and New England Cottontail • In the field compare ear size and body size • New England have smaller ears and bodies • (95%) have a black line on the front edge of the ear (Easterns 40%) • In the laboratory skull characteristics and measurements and by DNA techniques.

  10. Sylvilagus floridanus (Eastern Cotton Tail)
