An ecological study of a reef-associated zooplankton community of Barbados, West Indies /Boers, Jacobus Johannes January 1988 (has links)
A reef-associated zooplankton community was monitored at weekly intervals for 53 weeks. Samples were collected from quadrats of dense coral cover using emergence net traps. The numerical and biomass fluctuations of 15 taxonomic groups, 7 size classes and 5 feeding groups of the community were determined both temporally and spatially. The community was composed of abundant and diverse taxa (81) with cyclopoid copepods being the most important taxon. Larger-sized fauna (e.g. amphipods, decapods, mysids, etc.) were the second most important abundance and biomass contributors. Size class analysis illustrated a bimodal size distribution spectrum. The well developed second mode of the spectrum was attributed to substratum characteristics which permitted an enhanced macrofaunal/detritivore presence. Although week to week fluctuations of the abundance/biomass data were marked, diversity indices indicated a persistent and resilient community. The nocturnal vertical migrations of the fauna did not show a persistent pattern with the varying phases of 12 sequentially monitored lunar cycles. Substratum heterogeneity was primarily responsible for the spatial distribution pattern of the fauna. Although the data variance suggested stochasticity, time-series procedures determined that cross-correlations between the numerical abundances of taxa, size classes and feeding groups occurred without a lead or lag. Similar analyses identified chlorophyll a as the important environmental variable and also as a leading indicator of particular taxonomic, size and feeding group abundances. It was concluded that reef-associated zooplankton communities are abundant, diverse assemblages structured by periodicities which in combination act to form important links between tropical, inshore benthic and pelagic ecosystems.

Reproductive ecology and distritution of the scleractinian coral Fungia scutaria in Kane‘ohe Bay, O‘ahu, Hawai‘iLacks, Amy L 08 1900 (has links)
In Hawaii, abundance of the scleractinian Fungia scutaria is thought to have been
in decline in recent years due to disturbances to Kaneohe Bay, where an unusually dense
population exists. This study examines factors that could limit population growth in this
coral. Sexual reproduction occurred throughout the summer. Experimental data from
sperm dilution studies suggested that eggs must be released within 2m of a spawning
male for successful fertilization to occur. Field surveys indicated that many patch reefs
exhibited high enough densities to yield successful fertilization. However, since field
surveys found that only a small percentage (1 %) of juvenile corals (5 cm in length)
resulted from settled larvae, post-fertilization processes may be limiting successful
recruitment. Asexual reproduction appears to be dominant, with 70% of corals occurring
in close aggregations, and 93% of these in aggregations made up of a single color-morph. / Thesis (M. A.)--University of Hawaii at Manoa, 2000. Includes bibliographical references (leaves 70-74).

The advantage of juvenile coloration in reef fishesMahon, Jeffrey L 12 1900 (has links)
Juvenile reef fishes often have a color pattern different from that of adults. It
has been theorized that this reduces the aggression received by juveniles from adult
conspecifics. This was tested using two species of Labroides cleaning wrasses in which
certain-sized individuals can quickly shift back and forth between the adult and juvenile
color patterns. Adult Labroides phthirophagus has the same single-male grouping
social structure as previously described for L. dimidiatus. Small L. phthirophagus and
L. dimidiatus in juvenile coloration shifted to adult coloration when isolated and then
quickly shifted back to juvenile coloration when chased by an adult conspecific female.
In L. phthirophagus the adult females attacked small cleaners more frequently when
they displayed the adult color pattern, indicating that juvenile coloration gives some
protection from conspecific aggression. Two other species oflabrids, Thalassoma
duperrey and Coris gaimard, showed the ability to shift back to juvenile coloration
when aggression was received from con specific adults, although the shift was not nearly
as rapid as seen in Labroides species.
Dascyllus albisella and Zebrasomajlavescens, common reef fishes, preferred to
solicit cleaning (by posing) from the adult-colored L. phthirophagus, indicating that
some hosts prefer the adult color pattern. Small L. phthirophagus shifted to adult
coloration more quickly when starved than when provided with host fish on which to
feed, indicating that the coloration shift is motivated by hunger. Even though juvenile coloration in some fishes may reduce the aggression
received from adults, in cleaner wrasses it also reduces food availability, making it
advantageous for them to shift to adult-coloration as soon as possible. Cleaner wrasses
have developed a quick, reversible coloration shift that allows changing to adult
coloration at a small size but allows reversing coloration if too much aggression is
received. / x, 59 leaves, bound : ill., maps ; 29 cm.
