    Oxygen exchange between CO2 adsorbate and TiO2 surfaces (1994)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: Using temperature-programmed desorption gas analysis, thermal desorptions of C18O2 and C16O18O with a small amount of C16O2 were observed in the temperature range 350–500 K after C18O2 was adsorbed on vacuum-annealed TiO2 powders at room temperature. This indicates that oxygen isotope exchange takes place between C18O2 gas and TiO2 surfaces. After 16O2 exposure of the C18O2-preadsorbed powders, the amount of C16O2 desorption increased, suggesting that isotope mixing may occur through a CO2-O2 intermediate complex.

    Notes: The vertical distributions of two herbivorous cichlid fishes, Tropheus moorii and Tropheus duboisi, were studied on the rocky slope at Luhanga and Bemba, 12 km apart, in Lake Tanganyika, Zaire, Africa. At Luhanga, where T duboisi were not present, T. moorii ranged from the shoreline to a site 30 m deep. At Bemba, T moorii occupied areas less than 18 m and T duboisi areas between 5 and 30 m. In the overlapping zone, 5–18 m depth, each fish held an intra- and interspecific feeding territory, involving size-dependent dominance relationship between neighbors irrespective of species. We indicate that the vertical distributions of these species are restricted by competitive interactions.

    Notes: In Lake Tanganyika the bagrid catfish Phyllonemus typus is a biparental mouthbrooder, the first such record among catfishes. Eggs and yolk-sac larvae are mouthbrooded by either or both parents, and following yolk-sac absorption, young are released temporarily from the mouth to feed beneath rocks which being guarded by both parents.

    Commensalism between cichlid fishes through differential tolerance of guarding parents toward intruders (1998)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: In the shallow waters of Lake Tanganyika, a benthic cichlid Xenotilapia boulengeri rests in a cluster around the nesting sites of substrate-brooding cichlids Lepidiolamprologus attenuatus and L. elongatus. Experimental removal of parent Lepidiolamprologus guarding free-swimming young drastically reduced the number of X. boulengeri around these nesting sites within a few days, suggesting that their presence has a positive effect on attracting X. boulengeri. Xenotilapia boulengeri were less frequently disturbed by the scale-eating cichlids Perissodus microlepis and Plecodus straeleni when they remained near nesting sites of these species than when stayed away. This was attributed to the territorial behaviour of guarding parents who drove away scale-eaters at greater distances, while allowing X. boulengeri, harmless to their young, to approach the nesting site. It is concluded that a clumped distribution of X. boulengeri results from differential tolerance of breeding parents toward intruders that produces a safety zone from scale-eaters.

    Obligate feeding of cichlid eggs by Caecomastacembelus zebratus in Lake Tanganyika (1999)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This study examined food habits of four common species of spiny eels (Mastacembelidae) in Lake Tanganyika to find if they eat cichlid eggs and larvae. Diets of Caecomastacembelus zebratus consisted nearly exclusively of eggs of substratum-brooding cichlids, whereas two other species fed on eggs only facultatively and one species never did. More than half individuals of C. zebratus had empty guts, although the mean weight of their gut contents was highest. This spiny eel ate many eggs in the first and second quarters of the lunar cycle when the spawning of substratum-brooding cichlids was active, while it nearly ceased eating in the latter half of the cycle. It is suggested that this fish is an obligate egg-eater and one of the predators that cause the high mortality of early cichlid broods.

    Seasonal pattern of filial cannibalism by Apogon doederleini mouthbrooding males (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 61 (2002), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: In temperate waters of southern Japan, mouthbrooding males of the cardinal fish Apogon doederleini sometimes ate their entire brood within a day of spawning. In spite of annual variation in age structure and length of the breeding season, however, the annual cannibalism rate (broods cannibalized to total broods spawned) was nearly constant, 12–16%. Fish 1 year old frequently cannibalized early broods of the season, especially the first brood, whereas the cannibalism rate by 2 year-old fish did not vary within the season. In contrast, the cannibalism by older males increased late in the season. This tendency was attributed to their different allocation patterns to growth and reproduction. For 1 year-old fish, which can enhance future reproductive success by growth and cannibalizing on early broods instead of mouthbrooding (at relatively low temperatures), this may be a tactic for investing energy in growth. For fish 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:00221112:JFB633:ges" location="ges.gif"/〉 3 years, which have more breeding cycles and grow little, cannibalizing late broods may be energetic compensation for their poor somatic condition. No seasonal variation of cannibalism by 2 year-old fish can be explained by their intermediate nature of growth and reproduction. Multiple mate availability is one factor facilitating the cannibalism by 2 and 3 + year-old fish whose operational sex ratio is female-biased.

    Alloparental care between catfishes in Lake Tanganyika (2001)

    Notes: A bagrid catfish Auchenoglanis occidentalis cared for its brood, deposited within an accumulation of shells and gravel in the centre of a large saucer-like depression, for up to 2 weeks in Lake Tanganyika. Adults of another catfish Dinotopterus cunningtoni (Clariidae) persistently came to A. occidentalis nests near days of host spawning. Eggs of D. cunningtoni were found in the host nests on the day and within 2 days of host spawning. During and for a few days after the end of host brooding, associate species' young of much older ages than the host brood were often found in the nests together with those of a similar age to the host young. Associate young were rarely found in nests before spawning and in unused nests. These findings suggested that this brood-mixing has two origins: egg dumping by associate adults and voluntary intrusion of large associate young into host nests. Possible benefits to the associate species are to take advantage of nest preparation and parental behaviour of the host species and to feed on the host brood.

    Lunar synchronization of spawning in cichlid fishes of the tribe Lamprologini in Lake Tanganyika (1990)

    Notes: Lunar synchronization of spawning was investigated for eight substrate brooding cichlid fishes belonging to the tribe Lamprologini. Their spawning activities all peaked during the second quarter of the lunar cycle. Comparison between their breeding styles and the degrees of spawning synchronization suggested that the nocturnal guarding-efficiency of eggs, especially exposed ones, is improved by the maximal amount of moonlight during full moon and, in species whose young leave the breeding sites about 2 weeks after spawning, the survival of dispersing young is enhanced by the darkness of moonless nights.
