Abstract: | Relatively little is known about large-scale spatial and temporal fluctuations in bacterioplankton, especially within the
bacterial families. In general, however, a number of abiotic factors (namely, nutrients and temperature) appear to influence
distribution. Community dynamics within the Vibrionaceae are of particular interest to biologists because this family contains
a number of important pathogenic, commensal, and mutualist species. Of special interest to this study is the mutualism between
sepiolid squids and Vibrio
fischeri and Vibrio
logei, where host squids seed surrounding waters daily with their bacterial partners. This study seeks to examine the spatial and
temporal distribution of the Vibrionaceae with respect to V. fischeri and V. logei in Hawaii, southeastern Australia, and southern France sampling sites. In particular, we examine how the presence of sepiolid
squid hosts influences community population structure within the Vibrionaceae. We found that abiotic (temperature) and biotic (host distribution) factors both influence population dynamics. In Hawaii,
three sites within squid host habitat contained communities of Vibrionaceae with higher proportions of V. fischeri. In Australia, V. fischeri numbers at host collection sites were greater than other populations; however, there were no spatial or temporal patterns
seen at other sample sites. In France, host presence did not appear to influence Vibrio communities, although sampled populations were significantly greater in the winter than summer sampling periods. Results
of this study demonstrate the importance of understanding how both abiotic and biotic factors interact to influence bacterial
community structure within the Vibrionaceae. |
