Ams Dates

After the abandonment of Mapungubwe, the Limpopo Valley was reoccupied first by Sotho people, making Icon pottery, and then by Kalanga speakers making Khami pottery. The senior Kalanga chief, in this case Twamamba, was based at Machemma about 60 km to the south, while several petty chiefs administered various portions of the valley itself. Because of fluctuating rainfall, the occupations of both Sotho and Kalanga people occurred in pulses during higher rainfall periods. New AMS dates place one site in the Icon Period, eight sites in Pulse 1 (AD 1400–1480) and eight sites or components in Pulse 2 (AD 1520–1590). Kalanga people occupied the best agricultural land near the Limpopo floodplains and Sotho people lived on the plateau to the south. The two groups thus shared the landscape, but not the resources equally. The ceramic record documents this unequal interaction. This interaction, facilitated by male and female initiation schools on the ethnic boundary, helped to create Venda as a language and macro-cultural entity.

AbstractThe genus Endeius Coiffait & Sáiz, 1968 (Staphylininae: Staphylinini), distributed from Chile and Argentina through Juan Fernández Is. and Galapagos Is., is revised using characters of external morphology and male and female genitalia. Endeius comprises seven valid species: E. punctipennis (Solier), E. nitidipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz, E. franzi Sáiz, E. lugubris Sáiz and E. ovaliceps Coiffait. Belonuchus multipunctatus (Coiffait), comb. nov., is excluded from Endeius. An identification key to all species of the genus is provided. Monophyly of Endeius, as considered in the present study, is supported by one synapomorphy from the external morphology. Within the genus, the best supported subgroup consists of E. punctipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz and E. ovaliceps Coiffait.

A 3-year study of fish from the South River, and the South Fork of the Shenandoah River, and the Shenandoah River in Virginia revealed significant differences in the muscle mercury content of males and females. Female rock bass, Ambloplites rupestris, redbreast sunfish, Lepomis auritus, pumpkinseed, Lepomis gibbosus, and bluegill, Lepomis macrochirus contained higher levels of mercury than the males of each species. An analysis of these species indicated that sex-related differences in mercury levels were not due to differences in body size but may have been related to the onset of reproduction. For example, mercury levels in 1-year-old male and female redbreast sunfish were not significantly different: females averaged 0.66 μg Hg/g and males averaged 0.63 μg Hg/g. However, at 2 years of age, when redbreast sunfish first reproduce, females contained significantly more mercury than males: females averaged 0.84 μg Hg/g and males averaged 0.60 μg Hg/g. Analysis of the other species yielded similar results.

Anomalous Bodies

This chapter examines physicians' efforts to understand various types of anomalous bodies. Southern physicians who recognized race, sex, and place as essential aspects of bodies had to acknowledge that these categories were not always precisely defined. People could move from the North or from Europe to the South or from one place to another within it. Although custom and law defined all slaves as black, medicine was aware that interracial sex led to many bodies that combined the blood and thus the characteristics of the two races. Far less common, but certainly compelling to doctors, were bodies that exhibited aspects of both male and female. Physicians determined to define what was normal believed that studying bodies that fell between categories could help them understand health and illness. This chapter explores how southern physicians addressed the intellectual dilemmas posed by bodies of mixed race and by the ambiguous nature of women's bodies. It also considers how physicians thought about the maternal influence on the health of the fetus during the course of pregnancy.

A New Species

A new species of Arthrobrachus Solier, A. arquatus n. sp. from Argentina, is described using external characters of the adult male and female including terminal segments of the abdomen and genitalia. Arthrobrachus arquatus n. sp. is morphologically close to A. tibialis Solier, 1849 from the Central Chile sub region, suggesting a phylogenetic connection. Comments on the possible origin of this relationship are made.

Antarctic Fur Seals

This study examined the foraging locations of adult male and female Antarctic fur seals (Arctocephalus gazella) in the Scotia Sea during the postbreeding period. Satellite transmitters were used to track adult males and females and to obtain information about dive depths. Male fur seals migrated away from the breeding area during the postbreeding period whereas females remained close to the breeding grounds and foraged in the same area during two consecutive years. The most intensive foraging by females was associated with the edge of the continental shelf of South Georgia. Males dived deeper than females. Counts of males at South Georgia and at the South Orkney Islands support the result from satellite tracking data showing that males move from South Georgia to the South Orkney Islands at the end of the breeding season. Unlike males, females were limited in their foraging range by the necessity to return to feed dependent young, so breeding sites are likely to be located close to foraging areas that are optimal for females. Locations used for feeding by females were avoided by males, either because they were suboptimal for males or because foraging by females at South Georgia causes local depletion of food, and males, which have the option to forage further afield, can forage more successfully in regions where there are no females. Comparison with fisheries data also suggests that these fur seals are targeting the most abundant exploitable prey.

Males And Females

Analyses of morphological divergence in male and female Eptesicus in Western Australia are detailed. Phenetic differences between individuals at each locality, or nearby groups of localities, are examined for males and females separately, by canonical variate analysis. Populations can be roughly grouped into those of the South-west, North-west-Desert, Pilbara, Kimberley and the Peninsulas. Trends are evident from the analysis of the regional data for external morphological measurements. The South-west populations are referable to Eptesicus regulus Thomas, 1906. The moderately large Northwest-Desert populations are considered part of a general cline of Eptesicus pumilus extending north through the intermediate-sized Pilbara populations to the small Kimberley populations. The Peninsula populations have their greatest phenetic affinities with Eptesicus douglasi. In all populations examined, female Eptesicus tend to be larger than males.

Pedogenetic Processes

In this work, we present the results of a soil study in the Teuhtli volcano, located to the south of the Basin of Mexico with the aim to understand the pedogenetic pathways and the evolution of the landscape dynamics. Two different types of soil prof iles were sampled: in “conserved” areas, with less anthropogenic influence and in sites with intense agriculture activities since pre-Hispanic times. The three conserved prof iles are located in different landscape positions: the Cima prof ile in the summit, the Ladera prof ile in the high slope, and the Yotecón in a lower position of the piedemont. The agriculture prof iles are La Cruz, La Era and El Llano, situated in the foothill. Properties in both kind of soils are similar, however, in agriculture sites, structure (evaluated in macro and microscale) is weaker, total organic carbon content is smaller and bulk density is higher. Both soils show two main pedogenetic processes: andosolization and carbonate formation. Despite the age of the parent material (36 000 years), the Andosol phase has not been lost. This is because of the geomorphological dynamics of the zone, in which the processes of erosion and colluviation promote soil loss, restarting the pedogenetic clock. The detection of lithological discontinuities (by the Ti/Zr ratio) documents these processes. By the other hand, the formation of pedogenic carbonates is governed by the seasonal conditions of drought. The age of these carbonates places their formation in the mid-Holocene, an epoch for which drier conditions are detected in other sites of the Basin of Mexico. The agricultural land use has also promoted morphological, chemical and physical changes in the soils. The continuous tillage of the sites has prevented the soils from developing. This could have a negative effect on the fertility of those soils currently used to sustain the peri-urban agroecosystems of Mexico City.
