T increased connectivity of the global human population has amplified the frequency and effect of biological invasions and disease outbreaks. New trade routes among previously disconnected countries (Aide and Grau 2004) as well as enhanced transportation technology (eg airplanes and barges) have increased both the frequency and magnitude of invasions and potentially deadly disease outbreaks wor...

The precursor of porin, a mitochondrial outer membrane protein, competes for the import of precursors destined for the three other mitochondrial compartments, including the Fe/S protein of the bctcomplex (intermembrane space), the ADP/ATP carrier (inner membrane), subunit 9 of the F0-ATPase (inner membrane), and subunit 13 of the F,-ATPase (matrix). Competition occurs at the level of a common s...

Geographic Information Systems (GIS) is an innovative mapping technology used around the world to identify boundaries of geographic features, infrastructure, and myriad uses across the landscape. Historically a land-based application, the use of GIS in coastal ecosystems is growing (Nath et al. 2000, Babcock et al.2005, Dempster and Sanchez-Jerez 2008). Coastal areas are heavily used for shippi...

During the 1980s sufficient evidence accumulated to suggest that the use of cocaine and other illegal drugs by pregnant women presented a major public health problem (Frank et al. 1988; Neerhof et al. 1989). Prenatal alcohol and other drug abuse was occurring in all racial and ethnic groups and across all social strata. For example, the results of a study conducted in 1989 in Pinellas County, F...

Recently, numerous studies of aggregate response to freezing have been reported. Aggregate stability has usually been inversely proportional to soil water content at the time of freezing (Bullock et al., 1988; Benoit, 1973; Bryan, 1971; Logsdail and Webber, 1959). Aggregates from poorly aggregated soils, however, are more stable when frozen at intermediate water contents (Mostaghimi et al., 198...

Figure 1. Approximate distribution of harbor porpoise in the U.S. Pacific Northwest (shaded area). Stock boundaries separating the stocks are shown. STOCK DEFINITION AND GEOGRAPHIC RANGE In the eastern North Pacific Ocean, the harbor porpoise ranges from Point Barrow, along the Alaskan coast, and down the west coast of North America to Point Conception, California (Gaskin 1984). Harbor porpoise...

The characteristic heat shock or stress response is induced upon exposure of an organism (cell) to a number of environmental stressors, e.g. heat, anoxia and heavy metals (reviewed in Morimoto et al. 1990; Ellis and van der Vies, 1991). The heat shock or stress proteins are the most broadly distributed class of proteins known and amongst the most highly conserved. These stress proteins and thei...

Cell migration during morphogenesis and organogenesis is under strict spatial and temporal control. Several lines of evidence suggest that migration is regulated by interactions of cells with the extracellular matrix (ECM) (see reviews by Thiery, 1985; Bronner-Fraser, 1990; Johnson et al., 1990). These interactions take place between cell surface receptors and their ECM ligands, among which fib...
