Using high resolution X-ray computed tomography data we examined the relationship between cochlear labyrinth volume and body mass in extant, non-primate euarchontoglirans, and in two fossils, to allow for comparison with the results of Kirk and Gosselin-Ildari (2009). Modern primates have significantly higher cochlear labyrinth volumes relative to body mass than other euarchontoglirans, which m...

Suppose that X is a two-dimensional Brownian motion. The trace X[0, 1] contains a self-avoiding continuous path whose Hausdorff dimension is equal to 2.

William Walker is professor of international relations at the University of St. Andrews in Scotland. He is the co-author with David Albright and Frans Berkhout of SIPRI’s Plutonium and Highly Enriched Uranium: World Inventories, Capabilities and Policies (forthcoming, 1996). There have been many recent cases of states reversing course. Russia has embraced capitalism and democracy, China has thr...

Atmospheric gas saturation levels were monitored throughout a 40-km reach of the upper Colorado River during the summer and fall of 1995 to identify possible sources of gas supersaturation in the river. Gas saturation data from seven fixed sampling points and 40 random sampling points were analyzed using analysis of variance (ANOVA) and multiple regression methods. The lowest total gas saturati...

Abstract Otolith strontium:calcium ratios were used to trace lifetime movements of American eels (Anguilla rostrata) captured in salt-water bays and adjoining freshwater ponds in Prince Edward Island, Canada. Eels were classiWed into migratory contingents based on their movement patterns. A pond with a pool-and-weir salmonid Wshway and a pond drained by a low-gradient channel contained eels tha...
