碩士 / 國立中興大學 / 植物學系 / 84 / A study on the diatoms of the travertine springs in Taiwan was
conducted from March 1995 to November 1995. Twenty-one springs
were visited and diatoms samples from thirty-eight stations were
collected. Seventy-five species and thirteen additional
varieties in twenty-three genera have been identified, including
ten species of Achnanthes, two species of Amphora and Caloneis,
one species of Grammatophora, Cocconeis, Denticula and
Cyclotella, fourteen species of Cymbella, two species of
Diatoma, four species of Diploneis, five species of Eunotia, two
species of Epithemia, Fragilaria and Hantzschia, five species of
Melosira and Nitzschia, three species of Surirella, seven
species of Gomphonema and Navicula, four species of Synedra, six
species of Pinnularia, one species of Rhopalodia and Stauroneis.
The description and illustrations of each diatoms are given.
Cluster analysis was used on the basis of presence absence data
to define the relationship between diatom taxa and different
dissolved CO2 gas content. The twenty-three genera of diatoms
can be divided into eight groups, and the eighty-eight species
of diatoms can be divide into fifteen groups. Using the same
method to define the relationship between diatom taxa and water
temperature, the twenty-three genera of diatoms can be divided
into ten groups, and the eighty-eight species of diatoms can be
divided into nineteen groups. However, from cluster analysis the
sampling stations of hot spring showed no obviously group of
diatom taxa in the dendrogram. Navicula tripunctata and
Nitzschia palea can be found throughout the study area with
different CO2 gas content and water temperature. It can be
considered that these two species of diatoms were tolerant
species to CO2 gas content and water temperature of the
environment. Diatom communities inhabiting the travertine
springs in Taiwan possess similarities with which inhabiting hot
springs in other countries. Especially, Achnanthes exigua,
Amphora ovalis and Cymbella affinis have been found all over the
world.
