J.G. Moore, D.A. Clague
2004, Geological Society of America Bulletin (116) 337-347
Black manganese-iron oxide crusts form on most exposed rock on the ocean floor. Such crusts are well developed on the steep lava slopes of the Hawaiian Ridge and have been sampled during dredging and submersible dives. The crusts also occur on fragments detached from bedrock...
The threat of silent earthquakes
Peter Cervelli
2004, Scientific American (290) 86-91
Not all earthquakes shake the ground. The so-called silent types are forcing scientists to rethink their understanding of the way quake-prone faults behave. In rare instances, silent earthquakes that occur along the flakes of seaside volcanoes may cascade into monstrous landslides that crash into the sea and trigger towering tsunamis....

From the field: Efficacy of detecting Chronic Wasting Disease via sampling hunter-killed white-tailed deer
Duane R. Diefenbach, C.S. Rosenberry, Robert C. Boyd
2004, Wildlife Society Bulletin (32) 267-272
Surveillance programs for Chronic Wasting Disease (CWD) in free-ranging cervids often use a standard of being able to detect 1% prevalence when determining minimum sample sizes. However, 1% prevalence may represent >10,000 infected animals in a population of 1 million, and most wildlife managers would prefer to detect the presence...
Exploring behavior of an unusual megaherbivore: A spatially explicit foraging model of the hippopotamus
R.L. Lewison, J. Carter
2004, Ecological Modelling (171) 127-138
Herbivore foraging theories have been developed for and tested on herbivores across a range of sizes. Due to logistical constraints, however, little research has focused on foraging behavior of megaherbivores. Here we present a research approach that explores megaherbivore foraging behavior, and assesses the applicability of foraging theories developed on...

Phylogenetic evidence for an ancient rapid radiation of Caribbean sponge-dwelling snapping shrimps (Synalpheus)
C.L. Morrison, R. Rios, J.E. Duffy
2004, Molecular Phylogenetics and Evolution (30) 563-581
A common challenge in reconstructing phylogenies involves a high frequency of short internal branches, which makes basal relationships difficult to resolve. Often it is not clear whether this pattern results from insufficient or inappropriate data, versus from a rapid evolutionary radiation. The snapping shrimp genus Synalpheus, which contains in excess...

K. Visser, R. Thunell, M.A. Goni
2004, Quaternary Science Reviews (23) 17-27
Recent studies convincingly show that climate in the Western Pacific Warm Pool and other equatorial/tropical regions was significantly colder (by ???3-4??C) during glacial periods, prompting a reexamination of the late Pleistocene paleoenvironments of these regions. This study examines changes in continental vegetation during the last two deglaciations (Terminations I and...
Assessing the record and causes of Late Triassic extinctions
L.H. Tanner, S. G. Lucas, M. G. Chapman
2004, Earth-Science Reviews (65) 103-139
Accelerated biotic turnover during the Late Triassic has led to the perception of an end-Triassic mass extinction event, now regarded as one of the "big five" extinctions. Close examination of the fossil record reveals that many groups thought to be affected severely by this event, such as ammonoids, bivalves and...
