Biocalcification processes in three coralline sponges from the Lizard Island Section (Great Barrier Reef, Australia): The Stromatoporoid Astrosclera, the Chaetetid Spirastrella (Acanthochaetetes) and the Sphinctozoid Vaceletia (Demospongiae)
(Geol. Inst. der Georg-august-Univ., 1996)
The main biocalcification events in the phylogenetically
distinct taxa Astrosc/era, S. (Acanthochaetetes) and Vace/
etia are described. Each taxon constructs its secondary
calcareous skeleton in its own highly specialized ...

New data on microbial communities and related sponge fauna from the Alkaline Satonda Crater Lake (Sumbawa, Indonesia)
(Geol. Inst. der Georg-august-Univ., 1996)
The small erater lake of the Island Satonda is characterized
by highly alkaline conditions as a whole probably due
to an intense sulfate reduction in the deep anoxic water
body. Some portions of the highly alkali ne ...

Lake Thetis domal microbialites
(Geol. Inst. der Georg-august-Univ., 1996)
Lake Thetis is a small saline lake with an increased alkalinity
and abundant domal microbialites. These microbialites
exhibit a rough stromatolitic structure. The recent growth
results mainly from calcifying ...

Biogeochemistry of modern Porifera and microbialites from Lizard Island (Great Barrier Reef, Australia) and fossil analogues
(Geol. Inst. der Georg-august-Univ., 1996)
Organic geochemical techniques were applied to study
the lipid conte nt of living reef organisms and rock sampies
trom different carbonate facies. The characterization of individual
organic compounds ("biomarkers") ...

Characterization on organic matrix proteins enclosed in high Mg-calcite crystals of the coralline sponge Spirastrella (Acanthochaetetes) wellsi
(Geol. Inst. der Georg-august-Univ., 1996)
Protein components found in freeze-dried specimens of
the coralline sponge Spirastrella (Acanthochaetetes) wellsi
were separated and characterized . Proteins extracted from
skeleton crystals (matrix proteins) contained ...

Holocene Ostracoda from the Satonda Crater Lake (Indonesia)
(Geol. Inst. der Georg-august-Univ., 1996)
The vertical distribution of Ostracoda from two digs from
the beach of the Satonda Crater Lake reflects the Holocene
history of its water chemistry. In the lowermost parts, monospecific
associations dominate in fresh ...

"Living fossil" sphinctozoan coralline sponge colonies in shallow water caves of the Osprey Reef (Coral Sea) and the Astrolabe Reefs (Fiji Islands)
(Geol. Inst. der Georg-august-Univ., 1996)
Three new types of aRecent colonial sphinctozoan coralline
sponge are presented. All types show close relationships
to the taxon Vaceletia crypta, a non colonial form from
Indo-Pacific reef caves. The first two types ...
