Community Ecology II: Species Interactions

Ecological communities: Assemblages of two or more species living and interacting in the same area.. Species interactions: the ways different organisms affect each other and how they have adapted to each other's presence.. FOUR main kinds of species interactions; all play a role in the formation

    1. Community Ecology II: Species Interactions

    5. Competition in Paramecium

    6. Competition in Paramecium

    11. Competition in Barnacles

    26. True Predators - prey is killed immediately upon successful attack

    27. Partial Predators - prey usually not killed but many prey organisms affected during predators lifetime - grazers, browsers

    28. Parasitoids - lay eggs on or in prey and then eggs hatch and developing offspring consume the prey

    30. Behavioral Defenses

    31. Morphological Defenses

    33. Aposematic or Warning Coloration

    34. Blue jay eats monarch, but vomits due to cardiac glycoside from milkweed

    35. Mimicry Batesian mimicry in which a palatable species mimics a harmful “model” species Müllerian mimicry in which two or more harmful species come to resemble each other

    36. Batesian mimicry – several fly species mimicking bees and wasps

    37. Batesian mimicry – coral and king snakes

    38. Müllerian Mimicry

    40. e.g. Wolves and Moose on Isle Royale

    43. Ticks (ectoparasites) suck blood and cause irritation Lead to weakened moose, which are more susceptible to predation by wolves and death from starvation.

    44. Parasites can also affect the behavior of the hosts, making them more likely to pass the parasite from one host to another.
