This issue of the Canadian Journal of Zoology exhaustively reviews most major aspects of protochordate biology by specialists in their fields. Protochordates are members of two deuterostome phyla that are exclusively marine. The Hemichordata, with solitary enteropneusts and colonial pterobranchs, share a ciliated larva with echinoderms and appear to be closely related, but they also have many chordate-like features. The invertebrate chordates are composed of the exclusively solitary cephalochordates and the tunicates with both solitary and colonial forms. The cephalochordates are all free-swimming, but the tunicates include both sessile and free-swimming forms. Here I explore the history of research on protochordates, show how views on their relationships have changed with time, and review some of their reproductive and structural traits not included in other contributions to this special issue.

History Of

There is a long history of research on the ormer, Haliotis tuberculata L., in the Channel Islands. Stephenson (1924) was concerned with the reason for the diminution in the number of ormers off the shores of Guernsey and undertook a three months' investigation during the summer of 1923 and published brief notes on his results for further investigation. Tanner (1926) also made some brief notes on various aspects of the biology and ecology of the ormer which he said were based on 30 years' observation. In two reports (1929, 1937), Crofts dealt with aspects of bionomics, anatomy and early development of ormers with brief accounts of reproduction. Brehaut (1957) reported tagging experiments on the movement and growth of ormers and Forster (1967I gave more detailed information on these aspects, having earlier (1962) published a study on the quantitative measurement of the ormer population.

There is an extensive history of research projects with Indigenous communities around the world where the projects were based on Western epistemologies and were neither collaborative, nor community- based.This editorial introduces the International Indigenous Policy Journal's special issue on the governance of Indigenous information. The issue opens a dialog about how data can be collected and governed in a way that empowers Indigenous peoples and communities.

Past Half

Here I survey a sample of the essays and reviews on the sciences of the long eighteenth century published in this journal since it was founded in 1969. The connecting thread is some historiographic reflections on the role that disciplines—in both the sciences we study and the fields we practice—have played in the development of the history of science over the past half century. I argue that, as far as disciplines are concerned, we now find ourselves a bit closer to a situation described in our studies of the long eighteenth century than we were fifty years ago. This should both favor our understanding of that period and, hopefully, make the historical studies that explore it more relevant to present-day developments and science policy. This essay is part of a special issue entitled “Looking Backward, Looking Forward: HSNS at 50,” edited by Erika Lorraine Milam.
