South Carolina naturalist John McCrady (1831–1881), a protégé of Louis Agassiz, was a pioneer in the study of Hydrozoa in North America. McCrady undertook investigations on hydrozoan life cycles, and provided thorough descriptions of most taxa. At least 20 of the families, genera, and species that he described and named are still recognised as valid. His ideas concerning classification and nomenclature within the Hydrozoa were remarkable for their time. As a result of the American Civil War, personal problems, cultural predilections, and preoccupation with other scientific interests, McCrady discontinued his hydrozoan research after 1860. Thereafter, his efforts in science were devoted to formulating a “Law of Development”, and to criticism of Darwinian theory.

Two years before Johann David Schöpf (1752-1800) published his Beyträge … (1787), Franz Joseph Märter (1753-1827) sent letters from Pennsylvania, Virginia, South Carolina, and East-Florida to Ignaz von Born, describing plants, animals, and geological features of the newly independent states. These letters were speedily printed in Physikalische Arbeiten … in Vienna (1785). A last letter sent from the Bahamas appeared in the same periodical in 1786. Märter's geological observations are translated and analyzed here for the first time. His descriptions of various rocks along the Schuylkill River, upstream from Philadelphia (granites, limestones, marble quarries, widespread weathered iron ores), and his interpretation of the fossiliferous sandstones in the Appalachian mountains are very similar to those by Schöpf. So are Märter's observations of shell banks, either exposed in ditches many miles from the sea, or in cliffs at Yorktown, Virginia, and Wilmington, North Carolina, as well as his description of granite and of a large coal mine near Richmond, Virginia. Finally, both travelers noticed that the rocky cliffs in the Bahamas consisted of limestone formed by Muschelsand [beachrock]. We established that Märter and Schöpf traveled together from Philadelphia to the Bahamas (November 1783 to March 1784). But neither acknowledged the influence, or at least the presence of the other, probably for political reasons.

We present four summers (2006–2009) of field observations of the Diana fritillary, Speyeria diana (Cramer, 1777), throughout the Southern Appalachian Mountains, USA, in the eastern portion of its distribution. We describe our observations of resource use by S. diana in sites located in Georgia, Tennessee, South Carolina, North Carolina, and Virginia. Butterflies imbibed nectar from five genera (>11 species) of flowering plants and also imbibed liquid from dirt roads and horse manure. The majority of butterflies (57%) were observed feeding on milkweed, Asclepias spp., a high-quality nectar-producing plant which is known to be an important resource for many Lepidoptera. We documented 14 species of Viola spp., the larval host plant used by Speyeria, in our survey sites. All butterflies were marked to observe their movement. Recapture rates ranged from 17% to 56%, suggesting that dispersal of S. diana out of suitable habitat was somewhat limited.
