This thesis incorporates the results of studies into
the distributions of the Cumacea whose members are one of
the groups of animals living in shallow water sands off
eastern Tasmania.
My approach assumes that patterns of animal distribution
exist. This may be regarded as an expression of
belief. However, as MacArthur (1927) has pointed out
most investigations of biological distributions reveal
pattern at some scale. The approach is supported also
by the work of Taylor, Woiwod and Perry (1978) who
suggested that spatial randomness is highly improbable
because the behavioural responses of living organisms
mediate dispersive processes.
1.1 Layout
The text of this account is divided into two main
sections. The first deals with the zoogeography of
shallow water cumaceans in eastern Tasmania. The
second section contains an account of cumacean spatial
distribution at the benthic interface and, briefly,
the place of these animals in the water column.
1.2 Timing
This project commenced in March, 1977. The formal
cut-off point for literature survey was June, 1979. All
literature quoted after that date results from browsing
or the intermission of friendly gatekeepers.
1.3 Statement of Intent
During a period of eleven years as a working
naturalist in Tasmania the geographic distribution of
the Tasmanian marine fauna has been of interest. The
concept of the Maugean marine province (Iredale and
May, 1916) proved a useful working hypothesis if only
because it provided a framework upon which to hang
observed distributions. This descriptive approach was
emphasized in a paper upon Tasmanian littoral biogeography
(Dartnall, 1974). Other work which is referred to
later in this text suggested that marine animal
distributions along the east coast of Tasmania were
interrupted by a discontinuity at the approximate
latitude of Maria Is. (c. 42o
31'S). Vernacular evidence
from other working zoologists offered nothing to refute
this view. It was with some surprise, therefore, to
read the work of King (1972) and to discover that the
distribution of littoral algae did not support the concept
of a Maugean marine province. Both King and myself
have suggested that marine biogeographic regions should
reflect oceanographic conditions and that investigation
of Maugean distributions might continue profitably
offshore. This thesis is the result of that suggestion.
The pathways followed during this work are summarized
in a flow diagram following the conclusions. Logical
pathways are direct but labyrinthine logic plots its own
web. The actual routes followed are indicated.
