Of Dodos and Dutchmen: reflections on the nature of history

CRITICAL QUARTERLY, Issue 4 2005
FRANCIS GOODING
History-making is a defining property of the human species; the ability to retain information in symbolic form over time (an ability which is granted principally by the presence of true natural language) is a unique attribute of the human animal. It has allowed human beings to enter in a qualitatively different relationship with the physical environment, and to operate in and alter that environment in highly complex, highly effective ways. To a great extent, the types of events that structure this way of life are absent from the rest of the natural world; in order to describe them accurately, it is necessary to attend to the special quality which defines them, a quality which we can characterise as their 'historical-ness'. Descriptions of human events cannot overlook the histories that organise and determine them, and to that extent they are not fruitfully apprehended with the tools of the exact sciences and instead require attention from the social sciences; but nevertheless, the phenomena of history are a part of the natural world, since they are part of the life of the organism. History itself arises in the non-historical crucible of biology. The paper examines a particular suite of events which have distinct historical and non-historical aspects - the extinction of the Dodo - in order to explore the epistemological difficulties which necessarily complicate any attempt to view human conduct as an integrated part of the natural world.

The Place of Islam in the Geography of Religion: Trends and Intersections

GEOGRAPHY COMPASS (ELECTRONIC), Issue 5 2007
Richard Gale
This article reviews recent geographical research on Islam and Muslim identities. In the wake of the events of 11 September 2001, the forms taken by public debate surrounding Muslim communities and societies have been manifold and not always edifying. In the present political climate, where public attitudes to a particular suite of issues are often as misinformed as they are deeply held, the need for academics to furnish insights born out of robust research is acute. While the responses of academics to debates coalescing around Muslim communities and identities have emanated predominantly from religious studies, sociology and anthropology, geographers, with their attention to the spatial components inherent to the articulation of social identities, are making an increasingly significant contribution to our knowledge in this field. This article reviews this contribution, focusing on four areas in which geographical research on Islam has been most pronounced: Muslim residential segregation and ,community cohesion'; the relationship between Islamic dress codes and spatial context in the articulation of Muslim gender identities; the contestation of space that has attended the architectural expression of Muslim identity in urban landscapes and the spatial politics embedded in the construction of Muslim identities at simultaneously national and transnational scales. While the predominant focus is therefore geographical, the article also establishes linkages to other writings on the spatiality of Islam where relevant to the specific themes under discussion.

Digestive enzyme spectra in crustacean decapods (Paleomonidae, Portunidae and Penaeidae) feeding in the natural habitat

AQUACULTURE RESEARCH, Issue 3 2009
Maria Santos Reis Bonorino Figueiredo
Abstract This work describes the profile of five proteases and four carbohydrases from the crustacean decapods Macrobrachium australiense (Holthuis), Scylla serrata (Forskal), Portunus pelagicus (Linnaeus), Penaeus esculentus, Penaeus plebejus (Hess) and Metapenaeus bennettae (Racck & Dall), feeding in the natural habitat, in order to provide an indication of their digestive capabilities. The results raised the following points. First, species from each family showed a particular suite of digestive enzymes. Second, the activity of cellulase from M. australiensis and S. serrata, using AZCL-HE cellulose as the substrate, was around 90% higher than that observed with AZO-CM cellulose. However, for P. pelagicus and P. esculentus, the enzyme activity was better with AZO-CM cellulose. Third, M. australiense displayed the highest ratio of amylase to protease activity. In contrast, Portunidae species, P. pelagicus and S. serrata showed the lowest ratios. Fourth, comparison of the laminarinase activity of M. bennettae and P. esculentus in October (Spring) and December (early Summer) showed a significant decrease in December. Finally, the wide distribution of digestive enzymes in these crustaceans may reflect different feeding habits and habitats. [source]

Leaf dry matter content and lateral spread predict response to land use change for six subalpine grassland species

JOURNAL OF VEGETATION SCIENCE, Issue 2 2007
Nicolas Gross
Abstract Question: Land-use change has a major impact on terrestrial plant communities by affecting fertility and disturbance. We test how particular combinations of plant functional traits can predict species responses to these factors and their abundance in the field by examining whether trade-offs at the trait level (fundamental trade-offs) are linked to trade-offs at the response level (secondary trade-offs). Location: Central French Alps. Methods: We conducted a pot experiment in which we characterized plant trait syndromes by measuring whole plant and leaf traits for six dominant species, originating from contrasting subalpine grassland types. We characterized their response to nutrient availability, shading and clipping. We quantified factors linked with different land usage in the field to test the relevance of our experimental treatments. Results: We showed that land management affected nutrient concentration in soil, light availability and disturbance intensity. We identified particular suites of traits linked to plant stature and leaf structure which were associated with species responses to these environmental factors. Leaf dry matter content separates fast and slow growing species. Height and lateral spread separated tolerant and intolerant species to shade and clipping. Discussion and Conclusion: Two fundamental trade-offs based on stature traits and leaf traits were linked to two secondary trade-offs based on response to fertilization shade and mowing. Based on these trade-offs, we discuss four different species strategies which could explain and predict species distributions and traits syndrome at community scale under different land-uses in subalpine grasslands.
