Summary Introduction

To determine: If the biota is more likely to be derived by dispersal from another region or by vicariance.

Introduction: New Zealand has hardly any land vertebrates. Only one frog species, a few species of lizard and several species of flightless birds are known to be native to New Zealand. When a population (biota or taxon) gets separated geographically by physical barriers, such as a mountain range, or rivers into discontinuous populations, the groups evolve into new varieties leading to speciation, it is known as vicariance.

Summary Introduction

To determine: The significance of missing elements such as freshwater fishes.

Introduction: New Zealand has hardly any land vertebrates. No snakes, freshwater fish or terrestrial mammals are seen. Freshwater fishes are now seen in New Zealand, but these are recent arrivals and have a strong connection with other fishes from other southern lands.
