Seasonal Changes in Chemical Composition of Eurasion Watermilfoil (Myriophyllum spicatum L.) and Water Temperature at Two Sites in northern California: implications for Herbivory

We compared seasonal changes in Eurasian watermilfoil (Myriophyllum spicatum L.) characteristics and water temperature for a shallow poind in Davis, CA, and the Truckee River, near Tahoe City, CA. Tissue C and N were 15% lower in plants from the Truckee River than in plants from the Davis pond. Seasonal fluctuations in tissue N were also different. Mean phenolic acid content of Truckee River palnts (162yM g-1) was less than those from the shallow pond (195 yM g-1). Phenolic acid content was positively related to tissue C for Truckee River and Davis pond plants and, tissue C:N ratio for Truckee River plants. Mean monthly water temperature (1990 to 1998) for the Truckee River site was less than 20 C. Water temperatures were warmer in August and September at this site. However, Eurasian watermilfoil collected during these months was characterized by lower levels of tissue N. During a 29-month period beginning January 1994, mean monthly water temperature for the Davis pond exceeded 20 C, only during July to September 1995. Tissue N was generally greater during summer for watermilfoil growing in the pond. These results imply that Eurasian watermilfoil biological control agents may have different developmental rates in these habitats, and thus different impacts on watermilfoil populations

18th Century Mexican Majolica Sherds from the George C. Davis Site (41CE19), Cherokee County, Texas

During the late 17th-early 18th century, Spanish forces colonized the middle reaches of the Neches River and its tributaries when several missions were established for the Tejas and other Hasinai tribes in this locale: Mission San Francisco de los Tejas, 1690-1693, Mission El Santisimo de Nombre Maria (1690-1692), and Mission Nuestra Padre de San Francisco de Tejas (1716-1719, 1721-1730), otherwise known as Mission San Francisco de los Nechas. These missions were established along the Hasinai Trace, later known as El Camino Real de los Tejas . None of these missions have been located and identified in the many archaeological investigations that have been conducted in East Texas since the 1930s. It has been known, however, since 1940 that early 18th century artifacts have been found at the George C. Davis site (41CE19) on the Neches River at the crossing of the Camino Real. H. Perry Newell, the Works Progress Administration (WPA) excavator of the site, had noted in the published report on the 1939-1941 excavations at the George C. Davis site, that: some pieces of Spanish pottery found near a spring in one of the ravines cutting the slope a few hundred yards southeast from the mound [Mound A]…The Spanish ware were examined by Arthur Woodward, Los Angeles County Museum…The Spanish ware was analyzed as follows: “The fragment of blue and white glazed ware is Mexican majolica, made at Puebla, Mexico, sometime between 1700-76 but more than likely it dates from 1720-1750. This majolica from the George C. Davis site, about 20 sherds in total, has been recently relocated in the collections of the Texas Archeological Research Laboratory at The University of Texas at Austin. The sherds are from early 18th century (ca. 1720) Puebla Blue on White plates, a bowl, and a cup. Given the rarity of majolica on archaeological sites in East Texas outside of Spanish Colonial archaeological deposits, its presence at the George C. Davis site is especially intriguing given the fact that Mission San Francisco de Tejas/de los Nechas or Neches was built in this part of the Neches River valley in 1716, then rebuilt in 1721, and finally abandoned in 1730

The Henry Chapman Site (41SM56)

In the mid-1950s, Sam Whiteside conducted excavations at the Henry Chapman site, his site P-5 (41SM56), on Prairie Creek in eastern Smith County, Texas, some 18 miles east of Tyler, Texas. Mr. Whiteside was an amateur archaeologist who discovered and explored numerous sites up and down Prairie Creek as well as other important sites in Smith and adjoining counties. The Chapman site was one of the first sites to be investigated by Mr. Whiteside, and the major part of the work took place there in 1957 and 1958. In August 1957, the site was visited by Edward B. Jelks and Leroy Johnson, who viewed the excavations and examined artifacts collected from there. Mr. Jelks, in notes on record at the Texas Archeological Research Laboratory (TARL) at The University of Texas in Austin, Texas, on August 21, 1958, indicated after observing the artifacts from the Henry Chapman site that the ceramics indicated an Alto focus occupation. He recognized Hickory Engraved and Holly Fine Engraved wares as well as Dunkin Incised and possible Pennington Punctated-Incised sherds. He mentioned that no Crockett Curvilinear Incised or Weches Fingernail Impressed sherds were present (two common types present at the Alto focus type site, the George C. Davis site [41CE19]). E. Mott Davis also visited the site in late 1957, and in February 1959, Davis, Lathel F. Duffield, and William A. Davis collected skeletal material from the site. In a June 15, 1958, newsletter from the East Texas Archeological Society (ETAS), Mr. Whiteside described excavations at the Henry Chapman site that had revealed refuse pits, post holes, and an abundance of pottery sherds indicative of an Alto focus occupation. In the summer of 1983, Mr. Whiteside visited the University of Texas Field School at the George C. Davis site, where he loaned some of his notes and collections from the Chapman site for recording purposes (these are on file at TARL). After Mr. Whiteside’s death, his family graciously allowed me access to his notes and artifacts. Not all of the artifacts have survived, having been stored in paper bags and subjected to several moves, but thanks to Mr. Whiteside’s writing lot numbers on artifacts and listing them in a journal, a majority of them have survived, and thus are suitable for study. Although 50 years have passed since Mr. Whiteside’s work at the Henry Chapman site, it is my intent to now make that work public
