Title: Wildlife Ecology


1
Wildlife Ecology
  • Section 3 Part 1

2
Wildlife Ecology
  • What is ecology?
  • The study of the interrelations between plants
    and animals and their environment.
  • By understanding the needs of game, such as its
    habits and habitat, the hunter will have a more
    productive hunt.
  • The NRA has established a hunters code of ethics.
    The hunter will support conservation efforts
    which can assure good hunting for future
    generations of Americans.

Wildlife Ecology
  • Wildlife includes game animals
  • Which are given some legal protection, but must
    be hunted according to regulated seasons and bag
    limits.
  • Non-game animals (non hunted and protected
    species.
  • Wildlife is important as a source of beauty,
    biological study, recreation, and income.

4
Wildlife Ecology
  • Wildlife is sensitive to change and is a valuable
    indicator of environmental conditions.
  • Wildness
  • Is a condition of genetic and learned conditions
    which enable animals to successfully adapt to
    life in a natural environment.
  • Example of this is the wild and domestic turkey.

5
Wildlife Ecology
  • It is illegal to release pen-reared wild
    turkeys in Minnesota.
  • Ecosystem
  • A ever changing, interacting association of
    living organisms and the environment in which
    they live.
  • Food Chain
  • A series of organisms consisting of a food making
    plant, the organism that uses the plant for food,
    another organism that uses the plant consuming
    organism for food, and so on.

6
Wildlife Ecology
  • Herbivores
  • Plant eaters
  • Omnivores
  • Both Plant and Meat eaters
  • Population dynamics
  • Wildlife changes due to human activities and
    natural calamities.

7
Wildlife Ecology
  • What is habitat
  • Everything an animal needs to survive. Places
    for feeding, drinking, resting, breeding, and
    escaping danger.
  • The three main components of habitat are
  • Food
  • Shelter
  • Water

8
Wildlife Ecology
  • Limiting Factors
  • Carrying Capacity
  • Population limit
  • Compared to bucket of water.

9
Wildlife Ecology
  • Food
  • Cover
  • Water
  • Space
  • Predation
  • Weather
  • Human Activities
  • Diseases and Parasites
  • Self-Limiting Factors

10
Wildlife Ecology
  • Principle of Inversion
  • This means that as breeding populations increase,
    the production or survival of their offspring
    will decrease.
  • This results is an animal population composed of
    mostly older animals and very few young.
  • When breeding population declines usually the
    number of young per litter increases.

11
Wildlife Ecology
  • Principle of Compensatory Mortality
  • Applicable to death rate.
  • If one or more factors cause the death rate to
    decline, other factors will increase so that the
    overall death rate will not significantly change.

12
Wildlife Ecology
  • Wildlife and Plant Succession
  • This especially happens were a habitat is lost to
    fire or other natural disasters.
  • After a fire a forest or prairie start over in
    growth so habitat that was once there will not be
    any more. Year after year these areas will
    change and one day will be back to the original
    habitat.
  • Succession
  • Climax stage

13
Wildlife Ecology
  • Edge Effect
  • The edge or borders of habitat overlap each
    other.
  • There will be a noticeable change in vegetation.
  • The transition zone is the area were these
    different habitats overlap.
  • For many species this area is the best habitat
    because it offers a mixture of habitat.
