New Zealand has long been a conundrum to biogeographers, possessing as it does
geophysical and biotic features characteristic of both an island and a continent. This schism …

This chapter focuses on the evolutionary importance and taxonomic distribution of
euryhalinity. Euryhalinity refers to broad halotolerance (capability of surviving in both …

The galaxioid fishes are the dominant, most speciose group of freshwater fishes (with> 50
species) in the lands of the cool southern hemisphere, with representatives in western and …

Knowledge of the population biology of invading species will often be necessary to develop
effective management procedures and policies. But because invaders can have unexpected …

Abstract Knowledge of DNA evolution is central to our understanding of biological history,
but how fast does DNA change? Previously, pedigree and ancient DNA studies—focusing …

Vicariance is potentially a key biogeographic process (Rosen, 1978) that physically disrupts
populations—typically through geological upheaval—and leads to genetic divergence and …

River capture is potentially a key geomorphological driver of range expansion and
cladogenesis in freshwater‐limited taxa. While previous studies of freshwater fish, in …

Abstract We used DNA analysis of the freshwater Galaxias vulgaris complex (Pisces:
Galaxiidae) to test a geological hypothesis of drainage evolution in South Island, New …

Abstract Changes in lake and stream habitats during the growth and retreat of Pleistocene
glaciers repeatedly altered the spatial distributions and population sizes of the aquatic fauna …

The threat status of 74 freshwater and estuarine fish present in New Zealand was
determined. Fifty-one native taxa were ranked of which 67% were considered Threatened or …
