This is the first social history to explore the experience of British emigrants from the peak years of the 1960s to the emigration resurgence of the turn of the twentieth century. It scrutinises migrant experiences in Australia, Canada and New Zealand alongside other countries. The book challenges the assumption that the ‘British diaspora’ ended in the 1960s, and explores its gradual reinvention from a postwar migration of austerity to a modern migration of prosperity. Building on previous oral histories of British emigration to single countries in postwar years, it offers a different way of writing migration history, based on life histories but exploring mentalities as well as experiences, against a setting of deep social and economic change. The book charts the decade-by-decade shift in the migration landscape, from the 1970s loss of Britons’ privilege in destination countries and the 1980s urgency of ‘Thatcher’s refugees’, to shifting attitudes to cosmopolitanism and global citizenship by the 1990s. Key moments are the rise of expatriate employment, changing dynamics of love and marriage, the visibility of British emigrants of colour, serial migration practices, enhanced independence among women migrants and ‘lifestyle’ change ambitions. These are new patterns of discretionary and nomadic migration, which became more common practice generally from the end of the twentieth century.

ABSTRACTNotocotylus tadornae n.sp. is described from the New Zealand paradise shelduck Tadorna variegata (Gmelin), and Notocotylus gippyensis (Beverley-Burton, 1958), is recorded from three waterfowl species in New Zealand. The life histories of both species are shown to involve an hydrobiid snail Potamopyrgus antipodarum, as intermediate host. The taxonomic affiliations of N. tadornae and N. gippyensis are discussed.

Mysids typically form a large proportion of the hyperbenthic faunal biomass in estuaries and are central to the functioning of estuarine food webs. The population dynamics, annual life histories and reproductive effort of two common temperate estuarine mysids, Tenagomysis chiltoni and T. novae-zealandiae, are described in the intermittently open Kaikorai Lagoon, New Zealand. Mysids were sampled by night, monthly from September 2003 to September 2004. Both species completed their life cycles in the lagoon. There was an apparent spatial separation of breeding populations, with T. chiltoni prevalent in the upper lagoon and T. novae-zealandiae dominating the lower lagoon. Densities were lowest in late winter and peaked in late summer/early autumn for both species. Both species exhibited multivoltine life cycles, with breeding peaks occurring in October 2003, December 2003 and February/March 2004 for T. novae-zealandiae, and October/November 2003 and February/March 2004 for T. chiltoni. Breeding strategy for both species varied over the year with the adult size, brood size and the reproductive effort of both T. novae-zealandiae and T. chiltoni all being highest in spring. The life histories of both T. novae-zealandiae and T. chiltoni in the Kaikorai Lagoon are comparable to life histories described for other temperate estuarine mysid species in large open estuaries, and were not significantly modified to cope with the unpredictable demands of life in an intermittent estuary.
