  1. What are the two main types of predators?
    • Roving predators – search for prey
    • Sit and wait predators – wait for prey to come to them
  2. How do predators find & choose prey?
    • Most predators are non-random feeders 
    • 1. Search and encounter
    • 2. Pursuit and attack
    • 3. Capture and consumption
  3. What is the concept of net energy gain/ prey?
    • Is the organizing maximizing fitness? 
    • Net energy gain prey= Energy content pray - (search + pursuit + processing costs)
    • NEG= PE-(S+Pu+Pr)
  4. Why do animals eat what they eat?
    • Obtain energy to survive
    • Growing bigger to avoid predators/ wider range of prey
    • Reproduction
    • Wide diet
    • Fight diseases
    • Obtain Micronutrients (sodium/ calcium)
  5. Criteria predators might use
    select prey?
    • energy content
    • micronutrient content
  6. Moose diets are high in?
    Sodium
  7. Why do most predators eat variety prey?
    • Maximizing energy/nutrient gain requires
    • multiple prey types
    • Array of prey types varies seasonally/annually 
    • Avoiding predators restricts prey availab
    • Foraging Theory
  8. Brown thrasher
  9. Eastern towhee
  10. White-footed mouse
  11. Eastern Cottontail Rabbit
  12. Raccoon
  13. Southern Flying Squirrel
  14. Opossum

  23. Eastern mole
  24. Eastern fox squirrel
  25. Grey fox
  26. White-tailed deer
  27. What is biodiversity?
    • All species occurring in habitat & dynamics
    • Studies how it effects:
    • ecosystem function
    • competition
    • predation
  28. How does biodiversity affect ecosystems?
    • Keystone species
    •  Species richness positively correlated with important functional aspects ecosystems including
  29. What is the relationship between species richness & stability production?
    With an increase in plant tissue produced, the more species
  30. What mechanism produce the findings about the relationships?
  31.  Niche complimentary
     Facilitation (mutualism)
  32. What is mutualism?
    relationship where two species increased performance presence each other than alone
  33. Why conserve biodiversity?
    • We don't know what species will be useful in the future. 
    • Ecosystem services
    • tipping points- ecosystem substantially perturbed, never to be restored
  34. Who do we preserve biodiversity?
    • Ecosystem conservation
    • Maintain natural levels of environmental variation
  35. What can be taken from Environmental variation & stream fish
    diversity Coweeta Creek fishes 1991-2003?
    Fish diversity is highest when flow is low
  36. What about Calusa Indians & estuaries?
    • 40 different types of fish for food
    • tool material
    • material to build mounds
  37. Black Skimmer
  38. Laughing gull
  39. American Oystercatcher
  40. Willet
  41. Great blue heron
  42. Great egret
  43. Snowy egret

  49. Short-finned pilot whale
  50. Atlantic northern right whale
  51. Fin whale
  52. Sperm whale
  53. Humpback whale
  54. Sex Determination in Animals
  55. Sex controlled most vertebratessex
    chromosomesΔ sexes Δ chromosomes
  56. What is Hermaphroditism? Two types
    • Protogyny (female first then male)
    • Protandry (male first)
  57. What is Environmental Sex Determination?
    • temperature during
    • incubation determines sex (Found in some lizards, turtles, crocodilians & few
    • fishes)
  58. Pileated woodpecker
  59. Northern Flicker
  60. Prothonotary Warbler
  61. Swallow-tailed kite
  62. Black Vulture
