The tempo and mode of barnacle evolution.
TLDR
The results reject many of the underlying hypotheses about character evolution in the Cirripedia Thoracica, stimulate a variety of new thoughts on thoracican radiation, and suggest the need for a major rearrangement in Thoracican classification based on estimated phylogenetic relationships. Expand
Photobehavior of stony corals: responses to light spectra and intensity
TLDR
This work suggests that species whose tentacles remain continuously expanded have either dense algal populations in their tentacles, as in G. lobata, which has continuously expanded tentacles, or minute tentacles, like S. pistillata, where tentacles are expanded at night. Expand
Do clades of symbiotic dinoflagellates in scleractinian corals of the Gulf of Eilat (Red Sea) differ from those of other coral reefs
TLDR
This study amplified zooxanthellae 18S ribosomal DNA from symbionts of 11 coral species, and analyzed it with respect to RFLP and DNA sequence, suggesting that clade A is transferred through a closed system. Expand
Ammonium metabolism in the zooxanthellate coral, stylophora pistillata
TLDR
The results suggest that GDH activity and dark respiration rates may be used to estimate quantitatively the rate of ammonium excretion in S. pistillata, and that recycled nitrogen accounts for 90% of the zooxanthellae nitrogen demand. Expand
Zoogeography of Intertidal Communities in the West Indian Ocean as Determined by Ocean Circulation Systems: Patterns from the Tetraclita Barnacles
TLDR
The hypothesis that the distribution and connectivity of intertidal animals in the WIO are determined by the major oceanographic regime but less influenced by historical events such as Pleistocene glaciations is supported. Expand
Diurnal polyp expansion behavior in stony corals may enhance carbon availability for symbionts photosynthesis
TLDR
Carbon isotope budget of the coral tissue suggests that branched corals are more autotrophic, i.e., that they depend on their symbionts for nutrition compared to massive species, which are more heterotrophic and depend on plankton predation. Expand
Diurnal hysteresis in coral photosynthesis
TLDR
The direction of the diurnal hysteresis in variable fluorescence appears to be species-specific and may vary even within the same species, reflecting microscale variability in bio-optical properties and gross photosynthesis of the corals. Expand
Phylogeny of coral-inhabiting barnacles (Cirripedia; Thoracica; Pyrgomatidae) based on 12S, 16S and 18S rDNA analysis.
TLDR
The phylogenetic results allowed us to reject previous classifications of Pyrgomatidae based on morphological characteristics and suggested the possibility of paraphyly of the Pyrgom atidae. Expand
Orientation of Chelonibia patula (Crustacea: Cirripedia) on the carapace of its crab host is determined by the feeding mechanism of the adult barnacles
TLDR
It is concluded that larval choice of orientation at settlement is determined according to the direction of the current and the anticipated food-gathering ability of the adult barnacle. Expand
