Abstract Pseudelephantopus spicatus is a herbaceous plant native to the tropical areas in Mesoamerica, South America, the West Indies and Latin America; it has been introduced to Africa, Southeast Asia and some islands in the Pacific. It is reported to be naturalized in parts of Florida and Thailand. P. spicatus is regarded as a potentially pernicious weed of open ground.. As early as 1948 all available evidence then is said to have indicated that P. spicatus, however interesting as an addition to the adventive flora of the United States, is a potentially injurious weed which should be extirpated if possible before it becomes too thoroughly established.

After 1820, the day-to-day duties of the United States Navy involved dealing with smugglers, pirates, and the illegal slave trade and so deploying the large ships of the line was deemed unnecessary. Also, the successful completion of treaties with both England and Spain demilitarized the Great Lakes and stabilized the country’s southern border, easing concerns about a future foreign war. ‘A constabulary navy: pirates, slavers, and manifest destiny (1820–1850)’ describes the peacetime navy activities carried out by small squadrons of sloops and schooners acting as a constabulary force on distant stations abroad, mainly in the Mediterranean, but also in the West Indies, off Africa, in the Pacific, off Brazil, and in the East.

AbstractThe northeastern Pacific Ocean is a preferential location for the formation of closed low pressure systems. These slow-moving, quasi-barotropic systems influence vertical stability and sustain a moist environment, giving them the potential to produce or affect sustained precipitation episodes along the west coast of the United States. They can remain motionless or change direction and speed more than once and thus often pose difficult forecast challenges. This study creates an objective climatological description of 500-hPa closed lows to assess their impacts on precipitation in the western United States and to explore interannual variability and preferred tracks. Geopotential height at 500 hPa from the NCEP–NCAR global reanalysis dataset was used at 6-h and 2.5° × 2.5° resolution for the period 1948–2011. Closed lows displayed seasonality and preferential durations. Time series for seasonal and annual event counts were found to exhibit strong interannual variability. Composites of the tracks of landfalling closed lows revealed preferential tracks as the features move inland over the western United States. Correlations of seasonal event totals for closed lows with ENSO indices, the Pacific decadal oscillation (PDO), and the Pacific–North American (PNA) pattern suggested an above-average number of events during the warm phase of ENSO and positive PDO and PNA phases. Precipitation at 30 U.S. Cooperative Observer stations was attributed to closed-low events, suggesting 20%–60% of annual precipitation along the West Coast may be associated with closed lows.

This chapter takes a broad look at the Pacific Ocean in relation to Chinese migration. As trade, consumption and capital flows followed migrants, powerful networks were woven and sustained; in time, the networks fanned across the Pacific from British Columbia along the West Coast of the United States to New Zealand and Australia. The overlapping personal, family, financial and commercial interests of Chinese in California and those in Hong Kong, which provide the focus of this study, energized the connections and kept the Pacific busy and dynamic while shaping the development of regions far beyond its shores. The ocean turned into a highway for Chinese seeking Gold Mountain, marking a new era in the history of South China, California, and the Pacific Ocean itself.

‘Drinking and temperance’ describes the history of alcohol consumption in the United States and the introduction of the temperance movement. From the earliest European settlers to the fighters of the Revolution, Americans were among the world’s heartiest drinkers, producing their own corn beer and importing rum from the West Indies. The British blockades during the war meant access to rum was lost. Americans began to distill whiskey from corn instead, which became the country’s patriotic drink. Problems associated with heavy drinking resulted in reformers creating the temperance movement, a cause that was then taken up by Protestant preachers. In the 1850s, evangelicals lobbied for statewide prohibition laws, but there was no viable system of enforcement.
