Zoophilia (botany)

from Wikipedia, the free encyclopedia

As zoophilia (from ancient Greek ζώον zṓon , German 'animal, living being' and -philia ; not to be confused with the human paraphilia of the same name ) or zoogamy ( γάμος gámos , German 'wedding' ) is a characteristic syndrome in plants in botany that is associated with is accompanied by biotic pollination by animals ("animal bloom"), d. H. in general the adaptations of plants to all cases of biotic pollination, acquired through coevolution .

The opposite is a trait syndrome that develops in plants with abiotic pollination , such as anemophilia (pollination by wind) or hydrophilicity (pollination by water).

Hummingbirds feed on nectar and small insects that they find in flowers. Hummingbirds can pollinate flowers while foraging

Zoophilic plant species often have some of the characteristics that are typical of zoophilia:

  • staminocarpellate (= hermaphrodite ) flowers (stamens and carpels in the same flower)
  • striking colors, smells or structures for the pollinators. for example:
  • Resources usable by the pollinator, for example:
    • Pollen
    • nectar
    • Fatty oils
    • Resins
    • Scented oils
    • Sleeping places

In zoophilia, pollen is transported by animals. When visiting flowers, pollen is attached to the pollinator, often through sticky pollen tags or a textured outer layer, and then transferred to the stigma of a flower . With the transfer of the pollen to the stigma (in the case of naked samers on the pollination droplets) pollination is complete.

The stapelia -Art Stapelia gigantea with typical features one of blowflies pollinated plant: aasartiges appearance with hair like an animal carcass, penetrating odor of decay

Transport partners for zoophilic plants are:

The pollination of the snail carried pollen (Malakophilie) has been described several times (for example, aspidistra ), but is controversial (Daumann 1963).

Zoogamy is not to be confused with zoidiogamy , with which fertilization by flagellated sperm cells is meant.

If an animal species only uses one plant source (genus or family) it is referred to as oligo- or monolectic , if several sources are used then polylectic .

If a plant is mainly pollinated by one species it is called monophilic , if it is pollinated by several species it is polyphilic , or if it is pollinated by some related taxa it is called oligophilic .
