Ringkasan:
Salah satu misteri terbesar alam - 'Peri Lingkaran' dari Namibia - mungkin telah
terurai oleh para peneliti. Studi ini menunjukkan bahwa interaksi antara rekayasa
rayap dan organisasi-vegetasi sendiri bisa bersama-sama bertanggung jawab untuk
fenomena tersebut.

Penyebab patch melingkar dikelilingi oleh rumput, yang disusun dalam
pola seperti- sarang lebah di daerah-daerah besar dari Gurun Namib, telah
menjadi sumber perdebatan ilmiah selama beberapa dekade. Penelitian baru yang
dipublikasikan dalam journal ilmiah Nature , menunjukkan bahwa interaksi antara
rekayasa rayap dan organisasi- vegetasi sendiri bisa bersama-sama bertanggung jawab untuk
fenomena tersebut.
pola vegetasi biasanya membentuk lanskap spektakuler di seluruh
dunia, dengan Lingkaran Peri di Namibia memegang minat khusus bagi para ilmuwan
sejak 1970-an. Beberapa berpendapat bahwa rayap saja dapat membuat pola-pola
ini dengan menghancurkan vegetasi untuk mengurangi persaingan air, sementara
yang lain menyatakan bahwa lingkaran
mengikuti pola curah hujan dan semata-mata disebabkan oleh persaingan antara
tanaman.

New theory may
explain mystery of Fairy Circles of Namibia

One of nature's greatest mysteries -- the 'Fairy Circles' of Namibia -- may

between termite engineering and the self-organization of vegetation could be
jointly responsible for the phenomenon.
..............................
One of nature's greatest mysteries --
the 'Fairy Circles' of Namibia -- may have been unraveled by researchers at the
University of Strathclyde and Princeton University.
The cause of the circular patches of
earth surrounded by grass, which are arranged in honeycomb-like patterns in
huge areas of the Namib desert, has been the source of scientific debate for
decades. The new research, published in scientific journalNature, suggests that
the interaction between termite engineering and the self-organization of
vegetation could be jointly responsible for the phenomenon.
Regular vegetation patterns form
spectacular landscapes across the globe, with the Fairy Circles in Namibia
holding special interest for scientists since the 1970s. Some have argued that
termites alone create these patterns by destroying vegetation to reduce
competition for water, while others have suggested the circles follow patterns
of rainfall and are solely caused by competition between plants.
The newly-published findings show that
Fairy Circles may actually result from the close interaction between both
termites and vegetation, which facilitates their mutual survival.
Dr Juan Bonachela from the University
of Strathclyde's Department of Mathematics and Statistics, said: "There
have long been two theories on how these regular patterns, and especially Fairy
Circles, are formed, and both theories are normally presented as mutually
exclusive.
"Our findings harmonise both
theories and find a possible explanation for regular vegetation patterns
observed around the globe. In the case of Fairy Circles, termites remove
vegetation on their mounds to increase moisture, which is essential for the
insects' survival in dry environments, thus creating the bare disk. Vegetation
around the mound takes advantage of this water accumulation to grow, and this
taller vegetation forms the circle. Regular repetition of the pattern results
from different termite colonies competing next to one another.
"This behaviour affects the whole
ecosystem, allowing it to survive harsher conditions and recover from droughts
much more quickly than if there were no termites.
"The Fairy Circles remind us of
the delicate balance of interactions necessary to sustain ecosystems."
The findings come as a result of an
international collaboration between academics at Princeton and Strathclyde,
which allowed researchers to use their different expertise to develop and test
the theory.
Their multidisciplinary approach
included field data from four different continents and computer simulations.
Thanks to the latter, the authors were able to explore their theory on a
variety of scales, testing different environmental scenarios, which would have
been almost impossible to achieve on ground due to cost and time issues.
