Re-examining human-nonhuman relations among nomads of Eastern Tibet

In this paper, I explore how human-nonhuman relations among nomads of Eastern Tibet may be understood within the framework of a four-fold ontological system proposed by anthropologist, Philippe Descola. In what follows, I provide an account of Descola’s theoretical system, present ethnographic data on human-nonhuman relations from fieldwork with two nomadic communities in Eastern Tibet, and analyze these in light of Descola’s system. I argue that deep ethnographic engagement with and analysis of humannonhuman relations not only furthers our understanding of specific communities but also informs the politics around policies concerned with ‘the environment’.

Transforming history and myth: on the mutuality and separation of shared narratives in Eastern Tibet

Questioning the distinction between ‘cold’ and ‘hot’ societies, and an implied separation between myth and history, anthropologists have increasingly urged for an understanding of both myth and history as equally valid modes of shared social consciousness. This article takes up this point of view by referring to a written history of Lhagang, a town in Eastern Tibet; a history that appears to have the transformative content and oral circulation of myth. Using Lévi-Strauss’ structural analysis of myth and Santos-Granero's concept of topograms to demonstrate the mythemes that derive from the written history and circulate among Lhagang Tibetans, the article argues that, within the political and cultural context of Lhagang, myth and history shift in and out of indigenous categories even while being categorically distinct.

In the circle of white stones: moving through seasons with nomads of Eastern Tibet

This narrative of subsistence on the Tibetan plateau describes the life-worlds of people in a region traditionally known as Kham who move with their yaks from pasture to pasture, depending on the milk production of their herd for sustenance. Gillian Tan's story, based on her own experience of living through seasonal cycles with the people of Dora Karmo between 2006 and 2013, examines the community's powerful relationship with a Buddhist lama and their interactions with external agents of change. In showing how they perceive their environment and dwell in their world, Tan conveys a spare beauty that honors the stillness and rhythms of nomadic life.

Senses of waiting among Tibetan nomads

Ethnographic vignettes on how Tibetan nomads move describe a modality of waiting that is attuned to the rhythms and syncopations of movement through pastures and the life-cycle. Such waiting complements moving and is in time. How waiting is experienced reveals an important facet of one's synchronicity with time and place.

An ethnography of life and changes among Tibetan nomads of Minyag Dora Karmo, Ganzi Tibetan Autonomous Prefecture, Sichuan Province

This article describes the pastoral movements and material culture of a community of nomads in Eastern Tibet and how they negotiate changes brought about not only by national government policies and international development plans, but also by a local lama.

Wallace lines in eastern Gondwana : palaeobiogeography of Australasian permian brachipoda

The present Australian continent was a major component of the north eastern peninsula of Gondwana, itself the southern region of Pangaea, during the Permian period. Surrounding what is now Australia, were additional elements of north eastern Gondwana that are now incorporated into the tectonically complex regions of New Zealand, New Caledonia, the island of New Guinea, Timor, south east Asia, the Himalaya and southern Tibet. India was to the west and south west and Antarctica to the south. Marine water temperatures ranged from cold to temperate and tropical as Permian global climates ameliorated, global surface ocean circulation systems warmed, and due to rifting and northward drifting of some terranes.

Provincialism of global marine faunas was pronounced during the Permian and hence refined biostratigraphical correlations are often fraught with difficulty. The 'middle' Permian stratotypes approved by the International Subcommission on the Permian System have little direct relevance to correlations within the Gondwanan Region at the level of operational biostratigraphical zonal schemes. Brachiopoda are a dominant marine benthonic faunal element of Permian Gondwanan faunas and they provide refined correlations between marine basins within a specific faunal province. Modem faunal provinces are recognised by the distribution patterns of species and genera belonging to a single family or superfamily such as the Papilionoidea within the Insecta. This review provides an example from Permian Brachiopoda, using the distribution data of genera and subgenera of the superfamily Ingelarelloidea, in order to demonstrate the ability to define provinces and their 'Wallace lines' of demarcation between provinces in the geological past.

New materials of Ordovician nautiloids from Xainza,Tibet

Eastern Taerma bridge-Zhakang was found in recent years to be the second spot of Ordovician outcrop based on reliable fossils. The nautiloids described here include one new genus, two new species and one indeterminate species,which represent only a small fraction of the nautiloids collected from this area. They are new materials of Ordovician nautiloids that have been determined up to now, which enrich Ordovician nautiloid faunal assemblages as well as provide new data to both classification and correlation of the Ordovician for this area and geographical distribution of nautiloid fauna.

Peri-gondwanan permian correlations : the meso-tethyan margins

Correlations of the Permian sequences for sixteen regions of north eastern Gondwana during the Permian are presented in this review. These correlations are compared with Permian sequences of the Australian continent. Broad conclusions on palaeoclimatic change and tectonic events are summarised for six time intervals of the Permian Period.

The Asselian-Sakmarian-early Artinskian time interval indicates a change from cold to temperate depositional environments. Glacial deposits and low diversity Gondwanan marine faunas are succeeded by younger, warmer water, clastic and bioclastic sequences with moderately diverse marine faunas. Deposition of these sequences is occasionally associated with basaltic volcanism and initial rifting of the peripheral northern Gondwanan margin.

During the Late Artinskian-Kungurian (including Early Ufimian) time interval, climate amelioration occurred with the onset of carbonate deposition in several Cimmerian terranes. Basaltic volcanism in several terranes is indicative of significant rifting and the opening of the Meso-Tethys.

The Roadian (Late Ufimian) and Wordian-Capitanian (including Kazanian-Midian) time intervals were characterised by widespread, subtropical, marine carbonate depositional sequences. These occurred throughout the Cimmerian blocks as they drifted northward and on the more northerly parts of the Meso-Tethyan southern margin. These transgressive sequences may rest on significant unconformity surfaces. Equivalent carbonate units are known in the offshore and subsurface sequences of western Australia. Andesitic, convergent plate margin volcanism and volcaniclastic sequences are present in eastern Australia.

The Wuchiapingian time slice is characterised by widespread marine transgressions which extended into the north western basins of Australia.

The Changhsingian time slice is represented by relatively minor marine transgressive events in the Trans-Himalaya with the Selong section of Tibet being probably the most complete Permo-Triassic sequence for the southern margin of the Meso-Tethys.

Middle eastern refugees in fortress Australia

A Lopingian (Late Permian) brachiopod fauna from the Qubuerga formation at Shengmi in the Mount Qomolangma region of Southern Xizang (Tibet), China

A small fauna of 11 species belonging to 10 genera of Permian Brachiopoda from the lower part of the Qubuerga Formation outcropping near Shengmi village in the Qomolangma region of southern Xizang (Tibet) is figured and new taxa are described. New taxa are Quinquenella semiglobosa and Costatumulus shengmiensis. The fauna is most likely of Wuchiapingian (Djhulfian) age as indicated by the majority of the brachiopod species.

Permian brachiopods from the Selong Xishan section, Xizang (Tibet), China. Part 2: palaeobiogeographical and palaeoecological implications, spiriferida, athyridida and terebratulida

Brachiopods from the Selong Group at the Selong Xishan section indicate a typical Peri-Gondwanan affinity, but possibly a rapid invasion of tropical/subtropical Tethyan elements into the Himalayan region at the very end of Permian. A brief analysis of taphonomy and composition of the Selong fauna indicate that Selong Xishan lay on the shallow continental shelf near shore and brachiopods suffered substantial abrasion from contemporaneous wave action. Species of Spiriferida, Athyridida and Terebratulida are herein described and revised. New taxa are Nakmusiella selongensis nov. gen. et sp. and ? Bullarina striata nov. sp.

Effects of fragmented habitat and fire on the distribution and ecology of the swamp antechinus (Antechinus minimus maritimus) in the Eastern Otways, Victoria

This study investigated the distribution, habitat and population dynamics of the swamp antechinus (Antechinus minimus maritimus) in the eastern Otway Ranges. The species has a restricted, disjunct distribution and has been recorded at 25 sites between 1969 and 1999. All sites were located within 7 km of the coast, occurred at altitudes up to 80 m above sea level and within 10 m of a gully. Analysis of landscape site variables identified sun index as being significant in determination of the probability of occurrence of A. minimus. The presence of A. minimus is negatively associated with sun index, occuring at sites that have a southerly aspect and gentle slope. A. minimus was located in a range of structural vegetation including Open Forest, Low Woodland, Shrubland and Hummock Grassland and a number of floristic groups, some characterised by high frequencies of sclerophyll shrubs, others by high frequencies of Pteridium esculentum, hummock grasses and herbaceous species. A. minimus occurs in fragmented, small populations with maximum population densities of 1.1–18 ha^–1. Populations at inland sites became extinct after the 1983 wildfire which burnt 41 000 ha. These sites have not been recolonised since, while on the coast the species did not re-establish until 1993–97. One population that is restricted to a narrow coastal strip of habitat is characterised by high levels of transient animals. The species is subject to extinction in the region due to habitat fragmentation, coastal developments and fire. Management actions to secure the present populations and ensure long-term survival of the species in the area are required and include implementation of appropriate fire regimes, prevention of habitat fragmentation, revegetation of habitat, and establishment of corridor habitat.

Selection of roost sites by the lesser long-eared bat (Nyctophilus geoffroyi) and Gould`s wattled bat (Chalinolobus gouldii) in south-eastern Australia

Physical characteristics of roost sites used by the lesser long-eared bat Nyctophilus geoffroyi and Gould's wattled bat Chalinolobus gouldii were investigated in a farmland–remnant vegetation mosaic and adjacent forested floodplain in south-eastern Australia. A total of 45 individuals of N. geoffroyi and 27 C. gouldii were fitted with radio-transmitters, resulting in the location of 139 and 89 roosts, respectively. Male N. geoffroyi roosted in trees, fallen and decayed timber and artificial structures. These roosts were low to the ground, mainly under bark and in cracks in timber. Roosts of female N. geoffroyi were located higher above ground, and all within trees. Maternity roosts were predominantly located in large dead trees, approximately twice the diameter of roost trees used by females outside the breeding season. No maternity roosts were found under bark, despite half the roosts used by non-breeding females being located in these situations. Both sexes roosted primarily in dead timber and used cavities where the narrowest dimension of the entrance was 2.5 cm. Most roosts of C. gouldii were in dead spouts on large, live river red gum Eucalyptus camaldulensis trees. Intraspecific differences in roost characteristics were less pronounced for this species. Despite access to the same roosting opportunities, there were marked differences in roost selection between N. geoffroyi and C. gouldii. Both species favoured large diameter trees, but differed significantly for all other measured variables: type of roost structure, condition of roost tree (live or dead), height of roost tree, height of roost, and entrance dimensions. Although these species are among the most widespread bats in Australia and are often considered to be habitat 'generalists', both displayed a high level of discrimination in the roosts used. Clearly, roosting requirements are a complex and important issue in the conservation of even the most common species of bats.

Some morphometric and biochemical features of ready-to-migrate silver and pre-migratory yellow stages of the shortfin eel of south-eastern Australian waters

The mean total length (L_T), mass and age of ready to migrate female silver shortfin eels Anguilla australis from the Hopkins River estuary and the mouth of the Merri River in south-eastern Australia, were 83·2 ± 1·2 cm, 1051 ± 51 g, and 17·2 ± 1·79 years, respectively. The eye index (I_E) of the silver shortfin eels was < 5·2 (mean 7·64 ± 0·29) and differed significantly from that of the yellow shortfin eels collected from two other sites. The I_E increased with L_T (mm) and was related by log I_E= 2·656 log L_T6·925. The per cent moisture, protein and ash content of the liver of silver shortfin eels was significantly lower than in yellow shortfin eels, but lipid content was significantly higher in the former (35·5 ± 2·0%). The mean mass μg mg lipid ‾) of saturates (230·4 ± 2·6 v. 181·7 ±2·6), monoenes (367·4 ± 6·3 v. 290·8 ± 8·9) and PUFA (177·3 ± 5·3 v. 159·7 ± 4·6) in muscle was significantly higher, and the great majority of individual fatty acids was found also in higher quantities in silver shortfin eels. In the liver, the PUFA found in the highest quantity was 22:6n-3, except in shortfin eels from Hopkins River estuary, and the amount of 18:2n-6 in the liver of silver shortfin eels was significantly higher than that in yellow shortfin eels but the reverse was true of 20:4n-6. In both muscle and liver tissues the saturate 16:0 and the monoene 18:ln-9 collectively accounted for >50% of all the fatty acids in the lipid.
