13. Respiratory Pathogens in Monkeys
Respiratory disease in a dynamic colony of nonhuman primates during a 4-year period was due primarily to infections caused by Klebsiella pneumoniae, Diplococcus pneumoniae, Bordetella bronchiseptica, Pasteurella multocida, and Haemophilus influenzae. The principal secondary invaders were Escherichia coli, Staphylococcus aureus, and streptococci. A high fatal

14. Linking climate change and biological invasions: Ocean warming facilitates nonindigenous species invasions
The spread of exotic species and climate change are among the most serious global environmental threats. Each independently causes considerable ecological damage, yet few data are available to assess whether changing climate might facilitate invasions by favoring introduced over native species. Here, we compare our long-term record of weekly sessile marine i

15. Hybridization as a stimulus for the evolution of invasiveness in plants?
Invasive species are of great interest to evolutionary biologists and ecologists because they represent historical examples of dramatic evolutionary and ecological change. Likewise, they are increasingly important economically and environmentally as pests. Obtaining generalizations about the tiny fraction of immigrant taxa that become successful invader

16. Reduced genetic variation and the success of an invasive species
Despite the severe ecological and economic damage caused by introduced species, factors that allow invaders to become successful often remain elusive. Of invasive taxa, ants are among the most widespread and harmful. Highly invasive ants are often unicolonial, forming supercolonies in which workers and queens mix freely among physically separate nests. By re

17. Differential shuffling of native genetic diversity across introduced regions in a brown alga: Aquaculture vs. maritime traffic effects
Worldwide marine invaders, such as the brown alga Undaria pinnatifida, offer challenging models for unraveling the apparent paradox of sustainable settlement of exotic species over a large spectrum of environments. Two intergenic noncoding mitochondrial loci were found to be highly informative at the within-species level. Twenty-five haplotypes were found ov

18. Recent biological invasion may hasten invasional meltdown by accelerating historical introductions
Biological invasions are rapidly producing planet-wide changes in biodiversity and ecosystem function. In coastal waters of the U.S., >500 invaders have become established, and new introductions continue at an increasing rate. Although most species have little impact on native communities, some initially benign introductions may occasionally turn into damagi

19. Role of Heat Shock Proteins in Protection from and Pathogenesis of Infectious Diseases
Increased synthesis of heat shock proteins (hsp) occurs in prokaryotic and eukaryotic cells when they are exposed to stress. By increasing their hsp content, cells protect themselves from lethal assaults, primarily because hsp interfere with the uncontrolled protein unfolding that occurs under stress. However, hsp are not produced only by stressed cells; som
