Pollination, Crypsis, Aposematic Coloration, and Mimicry

2-22-05


pollination

To transfer pollen from an anther to a stigma

stigma

anther


Orchid bees are both beautiful and good pollinators.


Aposematic coloration

conspicuous coloration or markings of an animal serving to warn off predators


Chinese Red-bellied Newt


Chinese Red-bellied Newt

If an animal has a dull back and bright undersides, the Unken Reflex may be used. They flash the bright colors, and frighten the predator.


Crypsis

Camouflage; blending in with surroundings


Killdeer on nest


The Fer-de-Lance relies on crypsis.


VALUE OF COUNTERSHADING

  • Many aquatic/marine animals are dark on top and light on the bottom. This is so predators approaching from the top see a dark back against a dark background, and predators from below see a light venter against a light sky.


mimicry

the resemblance of an animal species to another species or to natural objects; provides concealment and protection from predators


TYPES OF MIMICRY

  • Batesian mimicry: The model is poisonous/venomous, and the mimic is harmless.

  • Müllerian mimicry: The model is poisonous/venomous, and the mimic is, too.


The mimic - Milk snake - non-venomous

The model - Coral snake - venomous

BATESIAN MIMICRY


MORE NON-VENOMOUS BATESIAN MIMICS


ANOTHER BATESIAN MIMIC.


Mimicry is favored by selection and passed on to future generations (evolution)
