Asia minor bluegrass (AmB) is a major weed impacting rapeseed production in Dongting Lake District, China. Growth chamber experiments were conducted to determine the influence of environmental factors on germination and emergence of AmB. The optimum constant temperature for germination was around 20 C. Seeds showed germination percentages above 60% under 22/15 and 24/19 C day/night temperature regimes. Seeds could germinate in the dark, but light exposure significantly enhanced the germination percentage. More than 50% of seeds germinated over a pH range between 4 and 10. Seeds were highly sensitive to osmotic stress, and germination was completely inhibited at an osmotic potential of −0.4 MPa, indicating that it was favored by a moist environment. Increasing salinity reduced germination of AmB seeds from 58% at 0 mM to 13% at 80 mM NaCl. The highest seedling emergence (62%) was observed when seeds were placed on the soil surface, and no seedlings emerged from seeds placed at a depth of 5 cm. This work shows that the climate and soil conditions in Dongting Lake District are suitable for AmB seed germination and that no-till fields, where seeds remain on the soil surface, promote the successful establishment of the weed.

Absent Presence

Reading the clues embedded in extant clothing demands both imagination and patience since the subtle marks of wear, use and alteration may only become evident with extended observation and reflection. During the course of a project undertaken in conjunction with the bicentenary celebrations of John Ruskin's birth culminating in the exhibition of Sarah Casey's drawings in Ruskin's Good Looking! (8 February–7 April 2019), the authors studied the garments of John Ruskin at Brantwood, his former home in the Lake District. The life-sized drawings of these garments produced by Casey mapped the absent presence of the former wearer, allowed visitors the opportunity to better see and reflect on Ruskin's clothing, and also revealed the hidden histories of Ruskin's garments. Drawing, the making of marks with meaning, is not an obvious research tool in dress history and curatorial practice but, as this case study shows, can expose subtle details and reveal new insights.

Many of the stakeholders involved in modern geotourism provision lack awareness of how the concept essentially ermeged, developed and was defined in Europe. Such stakeholders are unaware of how many of the modern approaches to landscape promotion and interpretation actually have nineteeth century antecedents. Similarly, many of the apparently modern threats to, and issues around, the protection of wild and fragile landscapes and geoconservation of specific geosites also first emerged in the ninetheeth century; the solutions that were developed to address those threats and issues were first applied in the early twentieth century and were subsequently much refined by the opening of the twenty-first century. However, the European engagement with wild and fragile landscapes as places to be appreciated and explored began much earlier than the nineteenth century and can be traced back to Renaissance times. The purpose of this chapter is to provide a summary consideration of this rather neglected aspect of geotourism, initially by considering its modern recognition and definitions and then by examining the English Lake District (with further examples from Britain and Australia available at the website) as a particular case study along with examples.
