A new podocarpaceous conifer is described from the early Danian Salamanca Formation (southern Chubut, Patagonia, Argentina) based on compressions of leafy branches with cuticular remains. Kirketapel salamanquensis gen. et sp. nov. has amphistomatic, scale-like leaves with marginal frills distinguishable at the apex; stomata oriented randomly in relation to the major axis of the leaf with four to five subsidiary cells and extremely reduced Florin rings; and irregularly shaped epidermal cells. We compare K. salamanquensis with extant and extinct members of the imbricate-leaved podocarps, among which it closely resembles Florin’s Dacrydium group C genera (i.e., Lagarostrobos, Manoao, Lepidothamnus and Halocarpus). Among these genera, only Lepidothamnus has a living representative in South America, the Chilean L. fonkii, whose leaf macro- and micromorphological characters are described in detail for comparison. Overall, the Patagonian fossil species is most similar to the extant and extinct members of Lagarostrobos in its cuticular micromorphology; however, macromorphological characters, such as the leaf size, apex curvature and mode of flattening, clearly differentiate it from all four genera of Dacrydium group C. We include Kirketapel salamanquensis in a combined molecular and morphological phylogenetic analysis conducted under the maximum parsimony criterion. The new, early Paleocene fossil taxon is confidently recovered as part of the scale-leaved clade as defined herein, which also includes Halocarpus, Phyllocladus, Lepidothamnus, Parasitaxus, Lagarostrobos and Manoao, and it constitutes the oldest record known for the group by at least 17 million years as well as its first fossil occurrence outside Australasia, establishing a widespread Gondwanan history. Furthermore, based on its oldest locality of occurrence, K. salamanquensis shows that the divergence of the total group of the scale-leaved podocarps occurred by at least 65 million years ago, adding to the growing systematic knowledge of earliest Cenozoic macrofloras in the Southern Hemisphere.

ABSTRACT The Aru Islands are situated at the eastern end of the Indian Ocean, in the southern Moluccas. They are also one of the easternmost places in the world where Islam and Christianity gained a (limited) foothold in the early-modern period, and marked the outer reach of the Dutch East India Company (VOC). The present article discusses Western-Arunese relations in the seventeenth century in terms of economic exchange and political networks. Although Aru society was stateless and relatively egalitarian and eluded strong colonial control up to the late colonial period, it was still a source of natural products, such as pearls, birds-of-paradise, turtle-shells, destined for luxury consumption in Asia and Europe. Aru society was thus positioned in a global economic network while leaving it largely ungoverned. Colonial archival data yield important information about the indigenous responses to European attempts to control the flow of goods. They both support Roy Ellen’s claim that the economic flows in eastern Indonesia extended beyond the control of VOC, and provide parallels to James Scott’s thesis of state-avoidance among the ethnic minorities in mainland Southeast Asia. 相似文献

A hoard was discovered at Mariesminde near the centre of the Danish island Funen in 2003 during trial excavations. A pot containing 27 bronzes was later excavated in the museum laboratory. The bronzes were stacked disorderly, with a large piece of sheet bronze at the bottom. The objects consisted of broken rings, several so-called ‘Hohlwulstringe’ or hollow rings, a socketed axe, plus 13 casting cakes and three casting runners. No less than four rings are types new to Scandinavia and reflect connections with the Italian peninsula and further away. The hoard's mixture of broken objects, casting runners and cakes classifies it as a scrap hoard. It is dated to the Bronze Age period VI (Montelius), prominently indicated by the hollow rings. The findspot of the hoard was only c. 200 m from the well-known period IV hoard Mariesminde I with the largest collection of gold vessels from Funen. The metal analyses open new perspectives and indicate an origin in the Alps or the Erzgebirge for most of the collection. 相似文献

ABSTRACTStrategic spatial planning is important for developing long-term visions and strategies towards regional and local sustainability. This paper explores if and how strategic spatial planning could be useful for overcoming some barriers related to new sustainable ways of heating residential areas, using district heating systems based on industrial excess heat. This longitudinal study builds on interviews with municipal and private actors in six Swedish municipalities. It highlights that important barriers can be overcome by influencing the design and location of residential districts and industrial activities. Further, it identifies missed opportunities in local spatial planning practice as stakeholders are involved late in the planning when much is set, leaving little space for stakeholders to have an impact. Consequently, there might be a lack of knowledge and expertise in how such issues could enhance planning. Strategic spatial planning could facilitate conditions for excess heat-based systems of district heating as it implies a broader systems perspective which could enhance a broader planning scope. Plan programs could bring about more strategic spatial planning processes as these require early stakeholder involvement. If taking stakeholder involvement one step further to stakeholder collaboration or co-production, an even broader planning scope would be achieved. 相似文献

ABSTRACTRecent historiographies of ‘Science and Empire’ have successfully critiqued older euro-centric narratives. They highlighted how science was ‘co-produced’ through interactions between knowledgeable European and non-European actors in colonial ‘contact zones’, and how this ‘pidginised knowledge’ circulated through networks across various sites within the British Empire. This article shares and expands this approach. By focussing on continental European scholars in Ceylon around 1900, it argues that scientific networks were never confined to a particular empire. Science among Europeans was, rather, multi-lingual, mostly cross-disciplinary and always transimperial. Applying such an approach to the history of science in late colonial Ceylon allows us to uncover entanglements between historical processes that have for too long remained subject matters of disconnected historiographies: the emergence of Buddhist revivalism, evolutionary theories about human origins, the transformation from ‘liberal race science’ to Nazi eugenics in Germany, and the surfacing of British cultural anthropology. 相似文献
