Abstract
Several factors lead to expectations that the scale of larval dispersal and
population connectivity of marine animals differs with latitude. We examine
this expectation for demersal shorefishes, including relevant mechanisms,
assumptions and evidence. We explore latitudinal differences in (i) biological
(e.g. species composition, spawning mode, pelagic larval duration, PLD),
(ii) physical (e.g. water movement, habitat fragmentation), and (iii) biophysical
factors (primarily temperature, which could strongly affect development,
swimming ability or feeding). Latitudinal differences exist in taxonomic
composition, habitat fragmentation, temperature and larval swimming,
and each difference could influence larval dispersal. Nevertheless, clear evidence
for latitudinal differences in larval dispersal at the level of broad
faunas is lacking. For example, PLD is strongly influenced by taxon, habitat
and geographical region, but no independent latitudinal trend is present in
published PLD values. Any trends in larval dispersal may be obscured by a
lack of appropriate information, or use of ‘off the shelf’ information that is
biased with regard to the species assemblages in areas of concern. Biases
may also be introduced from latitudinal differences in taxa or spawning
modes as well as limited latitudinal sampling. We suggest research to
make progress on the question of latitudinal trends in larval dispersal.
