International Journal of Speleology
Allozyme variation at 32 gene loci was studied in cave dwelling shrimps of the genus Troglocaris (fam. Atyidae). Populations were collected from several caves and wells belonging to different drainage systems in the Karst areas of NE Italy. Results suggest the existence of two sympatric, genetically distinct, biological species (provisionally indicated as species A and B in the T. anophthalmus complex) in the samples collected at the Duino Well, Sagrado and Comarie caves (Nei’s `D= 0.209). Samples from Gradisca and Aurisina are represented by only one (A) or the other (B) of the two species, respectively. Two remaining eastern populations …

Laboratory Studies Of Predatory Behaviour In Two Subspecies Of The Carabid Cave Beetle: Neaphaenops Tellkampfi, David M. Griffith
Laboratory Studies Of Predatory Behaviour In Two Subspecies Of The Carabid Cave Beetle: Neaphaenops Tellkampfi, David M. Griffith
International Journal of Speleology
Comparative studies on the foraging behaviour of Neaphaenops tellkampfi tellkampfi and N. t. meridionalis demonstrated adaptation to different environments. The southern subspecies N. t. meridionalis, which is found in wet muddy caves where cave cricket eggs are unlikely prey, did not locate buried cricket eggs and dug fewer and less accurate holes in the lab than the nominate subspecies. N. t. tellkampfi, which reaches high densities in sandy deep cave environments where cricket eggs are the only viable prey, gained significantly greater weight than meridionalis when presented buried cricket eggs as prey. There was no difference with respect …
Rupture Process Of The Macquarie Ridge Earthquake Of May 23, 1989, Jochen Braunmiller, John Nábělek
Rupture Process Of The Macquarie Ridge Earthquake Of May 23, 1989, Jochen Braunmiller, John Nábělek
School of Geosciences Faculty and Staff Publications
Broadband body waves recorded at 15 digital seismic stations worldwide are used to study the rupture process of the May 23, 1989 Macquarie Ridge earthquake. The centroidal solution (strike 211°, dip 86°, rake 180°, and depth of 10 km below the seafloor) indicates shallow rupture with pure right-lateral strike-slip motion along the Pacific-Australia plate boundary, in agreement with motion predicted by plate tectonic models. The total seismic moment is 13.4×1020 Nm, 80% of which was released in the first 24 s of the rupture process. Modeling favors a bilaterally propagating rupture with slightly different dip and rake for the …

Topographic And Volcanic Asymmetry Around The Red Sea: Constraints On Rift Models, Timothy H. Dixon, Erik R. Ivins, Brenda J. Franklin
Topographic And Volcanic Asymmetry Around The Red Sea: Constraints On Rift Models, Timothy H. Dixon, Erik R. Ivins, Brenda J. Franklin
School of Geosciences Faculty and Staff Publications
The Red Sea rift is asymmetric, with the locus of uplift and Tertiary volcanism in Saudi Arabia, 200–400 km east of the present rift axis. One model for this asymmetry involves simple shear extension on an east dipping, low-angle master fault that penetrates the lithosphere. Uplift and volcanism would mark the location where the fault enters the asthenosphere. However, observed seismicity, regional heat flow, and sedimentation are not in accord with this model's predictions. An alternate model involves interaction of upwelling asthenosphere in the early rifting stage with a nearby crustal weak zone such as a suture that controls rift …

The morphology of the Julian Alps and Prealps and of the Triestian Karst are here shortly described; the structures, which defined its origin and development, are also considered. We can notice some cliffs which follow one another from the State boundary to the Adriatic sea; they are made up by lithologic successions, which repeat themselves according to the latitude. Anyway we recognize a general outcropping of rock masses which are decreasing little by little southward as regards the altitude, the age and than the erodibility. There are some differences between the western (Carnian) and the eastern (Julian) bend of the …

Variation In Sulfur Dioxide Emissions Related To Earth Tides, Halemaumau Crater, Kilauea Volcano, Hawaii, Charles B. Connor, Richard E. Stoiber, Lawrence L. Malinconico Jr.
School of Geosciences Faculty and Staff Publications
Variation in SO2 emissions from Halemaumau crater, Kilauea volcano, Hawaii is analyzed using a set of techniques known as exploratory data analysis. SO2 flux was monitored using a correlation spectrometer. A total of 302 measurements were made on 73 days over a 90‐day period. The mean flux was 171 t/d with a standard deviation of 52 t/d. A significant increase in flux occurs during increased seismic activity beneath the caldera. SO2 flux prior to the this change varies in a systematic way and may be related to variation in the tidal modulation envelope.
