Chemical Ecology of Plants: Allelopathy in Aquatic and Terrestrial Ecosystems
Allelochemicals play a great role in managed and natural ecosystems. Apart from plant growth, allelochemicals also may influence nutrient dynamics, mycorrhizae, soil chemical characteristics, and microbial ecology. Synergistic action of various factors may better explain plant growth and distribution in natural systems. The book emphasizes the role of allelochemicals in shaping the structure of plant communities in a broader ecological perspective. The book addresses the following questions: (1) How do allelochemicals influence different components of the ecosystem in terms of shaping community structure? (2) Why is it difficult to demonstrate interference by allelochemicals (i.e., allelopathy) in a natural system in its entirety? Despite a large amount of existing literature on allelopathy, why are ecologists still skeptical about the existence of allelopathy in nature? (3) Why are there only scarce data on aquatic ecosystems? (4) What role do allelochemicals play in microbial ecology?.....

Scotland and the Sea
Alexander Fenton writes on the uses of shellfish as a way of examining the relationship between small-scale and large-scale fishing, and Ian Morrison investigates boat types in Shetland and in the Scandinavian islands. Shetland is explored again by Brian Smith's exposition of local fishing tenures. Gordon Jackson investigates the DPL shipping line before 1840 and Anthony Slaven writes about the business leaders in the great ship building firms of the Clyde. Robert Prescott breaks new ground by describing the Lascar seamen who were the origin of the Asian community in Glasgow, and Christopher Harvie and Stephen Maxwell write jointly on the political impact of North Sea oil.
The Elder Edda and Ancient Scandinavian Drama
Originally published in 1920, this book provides a theory of the dramatic origin of the older Eddic poems. Whilst the Eddic collection in general can be seen to contain a variety of unrelated elements, there is an essential unity to the older poems on native subjects. This can be seen in their special metre, their dialogic or monologic form, bearing traces of improvisation by one or more speakers, their stage directions, their stock scenes, their taste for disguised or theriomorphic characters, and their fixed traditional plots. In analysing this unity, the text brings forth observations on the relationship between the poems and the socio-cultural context in which they were written. This is a highly informative volume that will be of value to anyone with an interest in Old Norse literature and literary criticism.
