Milho Bt: teoria e prática da produção de plantas transgênicas resistentes a insetos-praga.

A biotecnologia moderna está gerando um grande número de genes passíveis de serem utilizados para a melhoria genética do milho, e as técnicas de transformação genética de plantas poderão ser empregadas para alterar a funcionalidade in vivo destes genes via complementação, superexpressão ou silenciamento. Progressos expressivos foram conseguidos no desenvolvimento da tecnologia de transformação genética de milho na última década. A transformação genética do milho, considerada por algum tempo problemática, tornou-se, atualmente, um procedimento de rotina para vários genótipos na maioria dos laboratórios públicos e privados trabalhando com esta cultura. Nesta Circular Técnica, serão abordados aspectos da produção e utilização em campo do milho Bt, englobando desde as pesquisas iniciais para o isolamento e caracterização dos genes cry, sua transferência para cultivares de milho via biobalística ou Agrobacterium, sua integração em programas de melhoramento clássico assistido por marcadores moleculares e utilização destas novas cultivares em campo.

Pastoral

This chapter argues that Milton’s Epitaphium Damonis, a neo-Latin pastoral lament on the death of Charles Diodati, is marked by the author's Petrarchan self-fashioning. This is achieved through intertextual engagement with Petrarch's Bucolicum Carmen (especially Ecls. 1 and 10). Milton as the wandering Thyrsis, undertaking a methaphorical and literal journey into the world of Italian humanism, appropriates and adapts the metaphorical departure from and return to a pastoral world now shattered by plague and death. Recourse to the quasi-Augustinian monasticism of Petrarchan neo-Latin pastoral facilitates the poem's crossing of a monastic limen via its subtle interaction with a hagiographic intertext, the Vita Sancti Deodati. Now pastoral saint and scholar become united in death and in subsequent apotheosis.

THE DISTRIBUTION AND POPULATION REGULATION OF THE WOOD MOUSE APODEMUS-SYLVATICUS ON FIELD BOUNDARIES OF PASTORAL FARMLAND

1. The population characteristics and distribution of wood mice Apodemus sylvaticus (L.) were investigated along field margins of farmland dominated by grass production. 2. Turnover, sex ratio, breeding season, spatial density dependence and density dependence in reproductive activity indicated that the population ecology of A. sylvaticus is consistent in different habitats in the same geographical region. 3. Spatial variation in the abundance of A.sylvaticus was related negatively to percentage of land under pasture and distance from woodland and positively related to variables associated with food supply and cover. 4. Variation in numbers of overwintered mice at the start of the breeding season was related more closely to breeding opportunity than to environmental factors. This was particularly so in males. 5. The association of overwintered male and female A. sylvaticus remained evident in the later half of the breeding season. Young males and females of the year, however, were distributed more with respect to physical and biological features than towards adults or reproductive opportunity. 6. A. sylvaticus is an important species of field margins, even where these are poorly developed and agriculture is pastoral rather than arable. Further studies of this species in a wider range of agricultural systems are desirable.

Iron Age Pastoral Nomadism and Agriculture in the Eastern Eurasian Steppe: Implications from Dental Palaeopathology and Stable Carbon and Nitrogen Isotopes

Iron Age societies of the eastern Eurasian steppe are traditionally viewed as nomadic pastoralists. However, recent archaeological and anthropological research in Kazakhstan has reminded us that pastoralist economies can be highly complex and involve agriculture. This paper explores the nature of the pastoralist economies in two Early Iron Age populations from the burial grounds of Ai-Dai and Aymyrlyg in Southern Siberia. These populations represent two cultural groups of the Scythian World - the Tagar Culture of the Minusinsk Basin and the Uyuk Culture of Tuva. Analysis of dental palaeopathology and carbon and nitrogen stable isotopes suggests that domesticated cereals, particularly millet, and fish formed a major component of the diet of both groups. The findings contribute to the emerging picture of the nuances of Early Iron Age subsistence strategies on the eastern steppe.
