INTRODUCTION Leaves develop as lateral organs from the peripheral zone of a shoot apical meristem. Initially, a group of cells is patterned along the proximal-distal axis and then establishment of the adaxial-abaxial axis is crucial for further leaf development. Subsequent cell proliferation along the medial-lateral axis results in flat and mediolateral symmetric leaves (Steeves and Sussex, 198...

The co-occurrence of alcohol use disorders, drug use disorders, and major depression has frequently been reported in alcoholic, drug abuse, and psychiatric patient samples (Allen and Francis 1986; Demilio 1989; El-Guebaly 1990; Ross et al. 1988; Rounsaville et al. 1982). Significant associations between substance use disorders and major depression have also been found in general population surv...

Allen and March provide a critique of one of our papers in which we argue composites should be represented as entities/objects in a conceptual model rather than relationships/associations (Shanks et al. 2008). They contend we have addressed a non-issue. Furthermore, they argue our theoretical rationale and empirical evidence have flaws. In this paper, we provide a response to their arguments. W...

BACKGROUND AND AIMS In the last decade, genomic studies using DNA markers have strongly influenced the current phylogeny of angiosperms. Genome size and ploidy level have contributed to this discussion, being considered important characters in biosystematics, ecology and population biology. Despite the recent increase in studies related to genome size evolution and polyploidy incidence, only a ...

Various versions of the ‘nativist–empiricist debate’ have been with us at least since John Locke formulated some of the basic principles of empiricist philosophy in the 17th century (Locke, 1690). As Allen and Bickhard suggest in their target article (this issue), empiricist and nativist perspectives have dominated the scientific landscape in pendulum-like alternation across the centuries. Most...

Introduction Paleontological data have been used for decades to address a series of very general and intrinsically interesting questions concerning speciation. Many of them are essentially microevolutionary, morphological or both. What is the relative prevalence of anagenesis and cladogensis (Wagner & Erwin 1995)? Do constraints on morphology cause occupation of morphospace to slow down as dive...

This paper is about our experiences of space in the Equator project (www.equator.ac.uk), in particular, the way in which multiple spaces, both virtual and physical, can co-exist. By this we mean that people and objects may have locations in and relationships to both physical space and one or more virtual spaces, and that these different spaces together interact to give an overall system behavio...
