DNA barcoding and the changing ontological commitments of taxonomy
This paper assesses the effect of DNA barcoding—the use of informative genetic markers to identify and discriminate between species—on taxonomy. Throughout, we interpret this in terms of varipraxis, a concept we introduce to make sense of the treatment of biological variation by scientists and other practitioners. From its inception, DNA barcoding was criticised for being reductive, in attempting to replace multiple forms of taxonomic evidence with just one: DNA sequence variation in one or a few indicative genes. We show, though, how DNA barcoding has not narrowed or reduced taxonomy in the way it was projected to. We examine the development and implementation of DNA barcoding across three kingdoms of life: animals, plants, and protists. Through this, we demonstrate that for DNA barcoding to work, the range of acceptable intra-specific variation needs to be demarcated from variation deemed to be characteristic of inter-specific differences. Consequently, biological processes responsible for particular patterns of variation need to be investigated and understood. This encourages an integrative disposition towards understanding and explaining the evolutionary processes affecting the rate and nature of change at the nucleotide level. We detail how the impact of DNA barcoding has manifested differently across the three kingdoms we examine, assessing this in terms of the ontological commitments that are held and instantiated in practice. Based on this evaluation, we consider the problem of studying multi-kingdom communities, and assess the consequences of our analysis for understanding classification and taxonomy.

Science and the garden : the scientific basis of horticultural practice
Most conventional gardening books concentrate on how and when to carry out horticultural tasks such as pruning, seed sowing and taking cuttings. This book is unique in explaining in straightforward terms some of the science that underlies these practices. It is principally a book of 'Why' - Why are plants green? Why should one cut beneath a leaf node when taking cuttings? Why do plants need so much water? But it also goes on to deal with the 'How', providing rationale behind the practical advice. The coverage is wide-ranging and comprehensive and includes the basic structure and functioning of garden plants, nomenclature, genetics and plant breeding, environmental factors affecting growth, methods of propagation and production, pest and disease control, and post harvest management and storage. Published on behalf of the Royal Horticultural Society, this book will be a most valuable text for those sitting the RHS general examination, and horticultural students at certificate and diploma levels; it will also appeal to gardeners, growers and scientists.
