The roles of environmental constraints and aggression on male-female pairing in the coral-reef fish Gobiosoma evelynaeHarding, Jeffrey A. 10 September 1993 (has links)
Early theoretical models for the evolution of male-female
pairing were based largely on studies of birds. These models
assumed that biparental care of eggs and young was an
essential component of pairing. However, male-female pairing
is also a relatively common social system in coral-reef
fishes, and biparental care of young is extremely rare in
this group. Although pairing has been documented in at least
13 families of reef fish, surprisingly little is known about
the environmental and social factors that may maintain
heterosexual pairs as the basic social units. I tested two
hypotheses for pairing in a common Caribbean fish, the
cleaning goby Gobiosoma evelynae, a territorial species which
inhabits living coral heads. According to the Environmental
Constraints Hypothesis, pairing in G. evelynae is simply a
consequence of three related environmental parameters--low
male mobility, low female density, and a uniform distribution
of resources required by females. On reefs off St. Thomas,
U.S. Virgin Islands, I found positive size-assortative
pairing, frequent male movement between territories, rapid
re-pairing by both males and females after experimental
removal of a partner, and random distributions of apparently
suitable coral heads required by females for territory space.
These patterns are inconsistent with the Environmental
Constraints Hypothesis for pairing.
Mate Guarding is an alternative hypothesis for pairing and
is based on social interactions. This hypothesis, which
states that paired gobies maintain exclusive access to their
partners by expelling all potential sexual rivals, predicts
sex- and size-specific aggression toward conspecifics.
released large and small male and female gobies directly onto
the territories of pairs, and recorded the behavioral
responses of the resident fish. As predicted, residents
exhibited the greatest aggression toward large intruders of
the same sex, and the least aggression toward large intruders
of the opposite sex. Unpaired territorial females also
responded aggressively to experimentally added females, and
ignored added males. These results indicate that male-female
pairs are maintained by mutual intrasexual aggression in this
species, and that females (and possibly males) defend both
partners and other resources associated with their
territories. / Graduation date: 1994

Food habits and prey size-selection of yellow perch in extreme southern Lake Michigan, with emphasis on the prey : round gobyTruemper, Holly A. January 2003 (has links)
Food habits for yellow perch Perca flavescens were compared using current and previous diet studies from southern Lake Michigan index sites. Yellow perch were not gape limited but size-selective in consumption of the newly established round goby Neogobius melanostomus. Ingested fish ranged from 7 to 47% of the yellow perch's total length and 2 to 53% of their gape. Currently, yellow perch diets are dominated in volume by fish/fish products (85%), which is double from previous studies. Utilization of zooplankton and insect prey items in the yellow perch diet has decreased to <1% by volume in 2002, contrasting with previous consumption of 4 to 20% and 5 to 17%, respectively, from previous studies during 1971-1993. Yellow perch are exhibiting opportunistic, generalist feeding strategy that incorporates both exotic and native prey items, allowing the population to use multiple prey items with the changing prey base in Lake Michigan. / Department of Biology
