2008, Icarus (193) 407-419
The surface of Enceladus consists almost completely of water ice. As the band depths of water ice absorptions are sensitive to the size of particles, absorptions can be used to map variations of icy particles across the surface. The Visual and Infrared Mapping Spectrometer (VIMS) observed Enceladus with a high...
Distribution of tsunami interevent times
E.L. Geist, T. Parsons
2008, Geophysical Research Letters (35)
The distribution of tsunami interevent times is analyzed using global and site-specific (Hilo, Hawaii) tsunami catalogs. An empirical probability density distribution is determined by binning the observed interevent times during a period in which the observation rate is approximately constant. The empirical distributions for both catalogs exhibit non-Poissonian behavior in...

E.A. Beever, J.L. Wilkening, D.E. McIvor, S.S. Weber, P. F. Brussard
2008, Western North American Naturalist (68) 8-14
The central tenet of island biogeography theory - that species assemblages on islands are functions of island area, isolation from mainlands, and vicariance - has been altered by the demonstrable effects that rapid climate change is imposing on insular faunas, at least in isolated mountaintops. Although populations of American pikas...
The A and m coefficients in the Bruun/Dean equilibrium profile equation seen from the Arctic
F. Are, E. Reimnitz
2008, Journal of Coastal Research (24) 243-249
The Bruun/Dean relation between water depth and distance from the shore with a constant profile shape factor is widely used to describe shoreface profiles in temperate environments. However, it has been shown that the sediment scale parameter (A) and the profile shape factor (m) are interrelated variables. An analysis of...

2008, Parasitology Research (102) 219-228
Laboratory populations of Tubifex tubifex from mitochondrial (mt)16S ribosomal DNA (rDNA) lineage III were generated from single cocoons of adult worms releasing the triactinomyxon stages (TAMs) of the myxozoan parasite, Myxobolus cerebralis. Subsequent worm populations from these cocoons, referred to as clonal lines, were tested for susceptibility to infection with...
Phylogenetic and ecological characteristics associated with thiaminase activity in Laurentian Great Lakes fishes
S.C. Riley, A.N. Evans
2008, Transactions of the American Fisheries Society (137) 147-157
Thiamine deficiency complex (TDC) causes mortality and sublethal effects in Great Lakes salmonines and results from low concentrations of egg thiamine that are thought to be caused by thiaminolytic enzymes (i.e., thiaminase) present in the diet. This complex has the potential to undermine efforts to restore lake trout Salvelinus namaycush...
Identification, prediction, and mitigation of sinkhole hazards in evaporite karst areas
F. Gutierrez, A.H. Cooper, K.S. Johnson
2008, Conference Paper, Environmental Geology
Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in evaporite terrains than in carbonate karst areas. This is because evaporites have a higher solubility and, commonly, a lower mechanical strength. Subsidence damage resulting from evaporite dissolution generates substantial losses throughout the world, but the causes...
