How to be a chaste species pluralist-realist: the origins of species modes and the synapomorphic species concept

The biological species (biospecies) concept applies only to sexually reproducing species, which means that until sexual reproduction evolved, there were no biospecies. On the universal tree of life, biospecies concepts therefore apply only to a relatively small number of clades, notably plants and animals. I argue that it is useful to treat the various ways of being a species (species modes) as traits of clades. By extension from biospecies to the other concepts intended to capture the natural realities of what keeps taxa distinct, we can treat other modes as traits also, and so come to understand that the plurality of species concepts reflects the biological realities of monophyletic groups. We should expect that specialists in different organisms will tend to favour those concepts that best represent the intrinsic mechanisms that keep taxa distinct in their clades. I will address the question whether modes of reproduction such as asexual and sexual reproduction are natural classes, given that they are paraphyletic in most clades.

Clinical research: how to be involved

The Northern Ireland Clinical Research Network (NICRN) undertakes research in a range of medical fields, which have recently been expanded to include mental health. The NICRN is part of a UK-wide initiative to provide opportunities for patients and clinicians to participate in high-quality clinical research.This suite of leaflets provides both the public and clinical researchers with an introduction to the work of the NICRN. They provide an overview of the NICRN's goals and highlight what the network can offer to patients, carers and researchers. Each leaflet includes specific details on the NICRN's work in that area and reasons why clinical research plays such a vital role in improving the delivery of health and social care
