horde-like from Central Asia as far as England, only to be driven back just
as quickly. Phylogeographers and palaeontologists alike now talk of
putative refugia and post-glacial recolonization to explain the
biogeographic history of populations of seemingly continuously distributed
continental species.
The present collection by Dr Ashraf Elewa of Minia University contains
papers about migration that are as timely as the subject is traditional.
Migration, it seems, is an ever-moving subject, and Elewa presents us with
a sampling of some of its current trajectories. Reyment discusses the
interpretation, and misinterpretation, of distributions of fossil marine
organisms in light of pre- and post-mortem movements. Elewa, in two
papers, considers the distribution of tiny but biostratigraphically important
ostracods in relation to the changing reaches of the shallow sea that
periodically inundated what is now northern Africa. Petrakis and Legakis
investigate problems of detecting and understanding insect migration in
Mediterranean ecosystems. Longer-term migration and adaptation in cold
water Pacific mollusc faunas are described by Amano. Thompson and
Russell take a particularly elegant look at phylogeographic structuring in
the mtDNA in salamanders in the Pacific Northwest. The Miocene
Vallesian Crisis, a time when the subtropical forest faunas of Europe
virtually disappeared during a cooling episode, is used by Casanovas-Vilar
et al. to investigate the geographic restructuring of entire faunas and floras.
The final paper of the book, by Hortal et al., contains a creative
quantitative study of the provincializing effect of basin and range
structures in Iberia on mammalian communities and an extrapolation by
GIS modelling to see whether the same provincial structure existed in the
Palaeogene. Readers will get a flavour of the latest quantitative analyses –
GIS, faunal clustering, mtDNA phylogenetics – and a sense of the breadth
of international research in migration and biogeography.
