Ohne den Pollenübertragungs-Service blütenbesuchender Tiere könnten
sich viele Blütenpanzen nicht geschlechtlich fortpanzen. Die komplexen
und faszinierenden Bestäubungsvorgänge bei Blütenpanzen sind
Ausdruck von Jahrmillionen von Selektionsvorgängen, verbunden mit
Selbstorganisation der Lebewesen; eine Sicht, die auch Darwin schon
unterstützte.
Bei vielen zwischenartlichen Beziehungen haben sich zwei oder auch
mehrere Arten in ihrer Entwicklung gegenseitig beeinusst. Man spricht
hier von sogenannter Coevolution.
Deutlich ist die Coevolution auch bei verschiedenen
Bestäubungssystemen und -mechanismen, die von symbiontischer bis
parasitischer Natur sein können.
Die Art-Entstehung, die Vegetationsökologie und die Entstehung von
Kulturpanzen sind eng damit verbunden

When disruptive vibrational signals
were applied to grapevine plants
through a supporting wire, mating
frequency of the leafhopper pest
Scaphoideus titanus dropped to 9 %
in semi-field conditions and to 4 % in
a mature vineyard. The underlying
mechanism of this environmentally
friendly pest-control tactic is a
masking of the vibrational signals
used in mate recognition and
location. Because vibrational
communication is widespread in
insects, mating disruption using
substrate vibrations can
transform many open field and
greenhouse based farming systems.

Pollination is very unusual in
Milkweed, because the pollen is
grouped into structures called
pollinia rather than being
individual grains..
The flowers of the milkweed are
very smooth and quite rigid,
usually pink or white pink in color,
while the leaves are a rounded,
oval and waxy to the touch and to
view. The insects will slip into
notches in the flowers, where the
bases of the pollinia which are very
sticky, will then attach to their feet,
so that they will pull the pollen
sacs free when they fly away.
Some bees, including some honey
bees, only gather nectar from
milkweed and since they visit no
where else, are not really effective
as pollinators for the plants.

Researchers have found an imported virus that may be associated with
the sudden disappearance of honey bees in the United States, known
as colony collapse disorder (CCD). This baffling syndrome, which earlier
this year made headlines around the world, may have afflicted as many
as 23% of beekeepers in the United States and caused losses of up to
90% of hives in some apiaries. The identification of a suspect is an
important step, says Nicholas Calderone of Cornell University. “Before,
we didn’t even have circumstantial evidence.”

After extensive training (80 foraging bouts and at least 640 flower visits),
bees reduced their flight distances and prioritized shortest possible
routes,whilealmost never following nearest-neighbour solutions.

Charles Darwin famously predicted the existence of a species of Madagascan moth (since aptly named Xanthopan morgani
praedicta), based on the shape of the nectaries of a species of orchid (Angraecum sesquipedale). Might it not be possible to take
a leaf out of Darwin's book and make similar deductions retrospectively? Could parasitologists not study tetrabothiids and other
modern parasites, and make deductions about their extinct ancestral hosts' lifestyles?
Beyond the Pollination Syndrome
Diurnal pollinators contributed less than nocturnal ones to fruit production, but the former were
moreconstant and reliable visitors through time. Our results indicate I. sessilis has floral
adaptations, beyond the morphology, that encompass both diurnal and nocturnal
pollinator requirements, suggesting a complementary and mixed pollination system.

The titan arum or Amorphophallus titanum is
a flowering plant with the largest unbranched
inflorescence in the world. The largest single
flower is borne by the Rafflesia arnoldii; the
largest branched inflorescence in the plant
kingdom belongs to the Talipot palm (Corypha
umbraculifera). The titan arum was originally
discovered by an Italian botanist, Odoardo
Beccari, in Sumatra in 1878. It thrives at the
edges of rainforests near open grasslands.
Though found in many botanic gardens
around the world it is still indigenous only to
the tropical forests of Sumatra. Due to its
fragrance, which is reminiscent of the smell of
a decomposing mammal,[1] the titan arum is
also known as a carrion flower, the "Corpse
flower", or "Corpse plant" (in Indonesian,
"bunga bangkai" – bunga means flower, while
bangkai means corpse or cadaver; for the
same reason, the same title is also attributed
to Rafflesia which, like the titan arum, also
grows in the rainforests of Sumatra).
