The approximately 700 species of cichlids found in Lake Victoria in East Africa are thought to have evolved over a short period of time, and they represent one of the largest known examples of adaptive radiation. To understand the processes that are driving this spectacular radiation, we must determine the present genetic structure of these species and elucidate how this structure relates to the ecological conditions that caused their adaptation. We analyzed the genetic structure of two pelagic and seven littoral species sampled from the southeast area of Lake Victoria using sequences from the mtDNA control region and 12 microsatellite loci as markers. Using a Bayesian model-based clustering method to analyze the microsatellite data, we separated these nine species into four groups: one group composed of pelagic species and another three groups composed mainly of rocky-shore species. Furthermore, we found significant levels of genetic variation between species within each group at both marker loci using analysis of molecular variance (AMOVA), although the nine species often shared mtDNA haplotypes. We also found significant levels of genetic variation between populations within species. These results suggest that initial groupings, some of which appear to have been related to habitat differences, as well as divergence between species within groups took place among the cichlid species of Lake Victoria. © 2013 Takeda et al.

Alternative reproductive tactics are widespread in males and may cause intraspecific differences in testes investment. Parker's sneak-guard model predicts that sneaker males, who mate under sperm competition risk, invest in testes relatively more than bourgeois conspecifics that have lower risk. Given that sneakers are much smaller than bourgeois males, sneakers may increase testes investment to overcome their limited sperm productivity because of their small body sizes. In this study, we examined the mechanism that mediates differential testes investment across tactics in the Lake Tanganyika cichlid fish Lamprologus callipterus. In the Rumonge population of Burundi, bourgeois males are small compared with those in other populations and have a body size close to sneaky dwarf males. Therefore, if differences in relative testis investment depend on sperm competition, the rank order of relative testis investment should be dwarf males>bourgeois males in Rumonge=bourgeois males in the other populations. If differences in relative testis investment depend on body size, the rank order of relative testes investment should be dwarf males>bourgeois males in Rumonge>bourgeois males in the other populations. Comparisons of relative testis investment among the three male groups supported the role of sperm competition, as predicted by the sneak-guard model. Nevertheless, the effects of absolute body size on testes investment should be considered to understand the mechanisms underlying intraspecific variation in testes investment caused by alternative reproductive tactics.

Despite the wide prevalence of alternative reproductive tactics, little attention has been paid to why reproductively parasitic males are so small. In this study, we tackled this issue in a shell-brooding fish Lamprologus callipterus. Sneaky 'dwarf males' of this fish remain much smaller than bourgeois conspecifics throughout their life and employ a unique parasitic tactic, i.e. entering into a gastropod shell where a female is spawning, passing through the space between the female and shell wall and staying behind her to ejaculate throughout the spawning event. Here, we tested the prediction that they remain small to get past her through the shell spaces by interpopulation comparison. We showed, across populations, a negative allometry for sexual size dimorphism, an exponential increase of female size with an increase in shell size and a negative correlation between the magnitude of sexual size dimorphism and shell size. These results suggest that the inner spaces strongly regulate dwarf male size. We conclude that the small bodies of dwarf males arise from adaptation to their unique reproductive behaviour.

When males are the larger sex, a positive allometric relationship between male and female sizes is often found across populations of a single species (i.e. Rensch's rule). This pattern is typically explained by a sexual selection pressure on males. Here, we report that the allometric relationship was negative across populations of a shell-brooding cichlid fish Lamprologus callipterus, although males are extremely larger than females. Male L. callipterus collect and defend empty snail shells in each of which a female breeds. We found that, across six populations, male and female sizes are positively correlated with not only sexual and fecundity selection indices, but also with shell sizes. Given their different reproductive behaviours, these correlations mean that males are required to be more powerful, and thus larger, to transport larger shells, while female bodies are reduced to the shell size to enable them to enter the shells. Among the three size selections (sexual selection, fecundity selection and shell size), shell size explained the allometry, suggesting that females are more strongly subject to size selection associated with shell size availability than males. However, the allometry was violated when considering an additional population where size-selection regimes of males differed from that of other populations. Therefore, sexual size allometry will be violated by body size divergence induced by multiple selection regimes.

More than 500 endemic haplochromine cichlid species inhabit Lake Victoria. This striking species diversity is a classical example of recent explosive adaptive radiation thought to have happened within the last similar to 15,000 years. In this study, we examined the population structure and historical demography of 3 pelagic haplochromine cichlid species that resemble in morphology and have similar niche, Haplochromis (Yssichromis) laparogramma, Haplochromis (Y.) pyrrhocephalus, and Haplochromis (Y.) sp. "glaucocephalus". We investigated the sequences of the mitochondrial DNA control region and the insertion patterns of short interspersed elements (SINEs) of 759 individuals. We show that sympatric forms are genetically differentiated in 4 of 6 cases, but we also found apparent weakening of the genetic differentiation in areas with turbid water. We estimated the timings of population expansion and species divergence to coincide with the refilling of the lake at the Pleistocene/Holocene boundary. We also found that estimates can be altered significantly by the choice of the shape of the molecular clock. If we employ the nonlinear clock model of evolutionary rates in which the rates are higher towards the recent, the population expansion was dated at around the event of desiccation of the lake ca. 17,000 YBP. Thus, we succeeded in clarifying the species and population structure of closely related Lake Victoria cichlids and in showing the importance of applying appropriate clock calibrations in elucidating recent evolutionary events.

We estimated the public opinion on paddy field aquaculture through a sensory test of cooked rice. The rice examined was cultivated with or without a crucian carp (Funa) rearing system on experimental paddies with no pesticide. Contents of amylose, starch and protein, which affect the quality of rice, did not show distinct differences between the Funa-reared rice and control rice. In a comparison with the quality of conventionally cultivated rice, 84 panels judged the palatability between the Funa-reared rice and control rice. The blind test detected no difference between the two, while the open test evaluated the former as more palatable. This disagreement implies that pesticide-free rural aquaculture has a favorable impression on today's consumers who are highly interested in food safety and environmental amenity.<br>

Wildlife and ecosystems characteristic of local environments are often used as environmental icons in the context of conservation and sustainable development. Based on the comparison among environmental icons used in the restoration of the oriental white stork in Toyooka, the conservation of the Shiraho coral reef and community development in Ishigaki, and the restoration of the traditional aquaculture of common carp in Saku, I have analyzed the formation processes and the role of environmental icons in catalyzing the unified activities of local stakeholders. The common momentum, in the formation of the environmental icons concerned, was their history of loss or crisis. The relevance to traditional resource use and local culture enhanced the attachment of stakeholders towards the icons, and the differentiated status of the icons unique to each local community augmented their pride of the local environment. Regeneration of ecosystems is required to restore these environmental icons and accompanied ecosystem services, which in turn provide incentives for consensus and cooperation among diverse stakeholders. Local residential research institutions play an important role in producing knowledge regarding ecosystem services and their implications to community development. Environmental icons effectively represent the ecosystem services of the local environment, thereby creating a mutual relationship among mankind, wildlife and supporting ecosystems, with mankind being the most influential ecosystem engineer and the beneficiary of the wide range of ecosystem services.

We made a detailed study of fishing activities by artisanal fishermen using gill nets and ecology of their target catfishes in 2000 and 2001 in Lake Malawi National Park in east Africa, where fishing activities seemed to coexist with the regulations of underwater protected areas (PAs) and fish stocks seemed to be maintained well. The overall ratio of the illegal nets in the PAs was 26%. Even though there was no effective law enforcement activity by the national park authority, fishermen tended to avoid setting nets near the boarder of PAs in the areas directly visible from the village, and they tended to use small cryptic buoys when they set nets inside the PAs. A large coastal area was relatively less exploited as a result of this unforced control, probably resulting in current good stock status of catfishes. We discuss the reasons of this unforced control in the light of acceptance of, and coexistence with the national park, interaction with external scientists, and local leadership.

In recent years, a large number of individuals of the species Latimeria chalumnae, one of the living fossil coelacanths, have been landed off the coast of Tanzania. Although L. chalumnae specimens have also been landed at other localities in the western Indian Ocean, so far, viable populations of this species have been identified only at two localities, Comoros and South Africa. Therefore, the recent active catch off Tanzania suggests a new habitat for L. chalumnae. To examine the genetic background of the Tanzanian fish, we analyzed complete mtDNA sequences of two Tanzanian individuals (Kigombe-9 and Songo Mnara-1) collected from the north and south coasts of Tanzania. Using the recently reported criteria for six haplotypes established in a population genetic study for coelacanths living in the western Indian Ocean [Schartl, M., Homung, U., Hissman, K., Schauer, J., Fricke, H., 2005. Relatedness among east African coelacanths. Nature 435, 901.], we characterized Songo Mnara-1 as haplotype I and Kigombe-9 as haplotype 5. We suggest that the Songo Mnara specimen is a member of the Comoran group, but was swept away by the South Equatorial current. The individual from Kigombe may be a member of an undiscovered population that exists near the boundary between Tanzania and Kenya. Further analysis using more than 19 individuals recently captured off the north coast of Tanzania will reveal whether a new population exists there. Our sequence data suggest additional variable sites in the mtDNA sequence that may define the population structure of coelacanths in the western Indian Ocean and also raise the possibility that the previously published Comoran coelacanth mtDNA sequence contains several critical errors including base changes and indels.

The behavior of two unicornfishes, Naso unicornis with a horn-shaped protuberance on the forehead and Naso vlamingii with a round protuberance, was observed in social and reproductive contexts in an aquarium. Males of both species performed displays that were associated with quick changes in the colors of the protuberance and other body parts, highlighting the protuberance by color contrast. The displays with color changes of the protuberance took place when a male courted a female in the evening or in the night. The same displays were occasionally performed by males toward females throughout the daylight hours. In N. vlamingii, dominant males displayed the protuberance toward subordinate smaller males. Although the sizes and shapes of the protuberance were sexually monomorphic, females of both species rarely made displays of the protuberance. A hypothesis about the function of the protuberance in unicornfishes is proposed: that males use the protuberance as a conspicuous signal in courtship and contests among males by emphasizing it with quick changes of its color contrasts. We argue that the combination of morphologically distinct protuberances and quick changes of their color is a sexually selected trait among unicornfishes, because these characters play important roles in intersexual and intrasexual interactions.

Question: Can intrasexual selection on male size and natural selection on female size in the shell-brooding cichlid Lamprologus callipterus explain the greatest male/female sexual size dimorphism (SSD) reported to date among animals?
Mathematical methods: (1) Mortality model to predict male and female body sizes. (2) Gain rate maximization and (3) combined mortality/gain rate maximization model to predict female size. We compared observed body sizes in the field with predictions from these models.
Key assumptions: (1) Body size at sexual maturity is determined by a trade-off between survival to sexual maturity and (a) number of mates in males and (b) fecundity in females. (2) Female body size is constrained by increasing search costs, because (3) shells large enough for breeding become limited as females become larger.
Results: (1) Male body size predicted by the mortality model matches size as found in the field closely, but the model strongly overestimated female size. (2) The female body size predicted by the gain rate maximization model fitted well within the range of sizes observed in the field. (3) Including the effect of mortality into this model hardly changes the prediction.
Conclusions: (1) Intersexual selection can explain male body size, but fecundity selection alone cannot explain female size. (2) The breeding substrate strongly constrains female size. (3) The extreme male-biased SSD is due to strong selection on the body sizes of both sexes in opposite directions.

Body shape differences between two benthophagous, sympatric cichlid species, Ctenopharynx pictus and Otopharynx sp. "heterodon nankhumba" were examined for 14 morphometric characters using measurements obtained from 11 morphological landmarks and additional 6 characters from the head region using principal component and regression analyses. The two species, though not closely related, superficially resemble each other and, being benthic feeders, directly compete for food resources unless morphological differences lead to trophic specialization. Hence, the present study explores the presence of such morphological variations. Principal component analysis (PCA), revealed that only four characters loaded highly on PC II and, therefore, account for most of the variations in the external morphology between the two species. C. pictus has longer lower jaws reflecting longer gape, and a shorter abdominal cavity than O. sp. "heterodon nakhumba". The regression analyses showed significant differences in the allometric coefficients of the lower jaw and abdominal cavity, which might have contributed to differences in overall shape detected between the two species. The difference in gape size between the two species may be related to different feeding habits employed by each species, and such specializations are suggested to reduce interspecific competition for food resources. We suggest that the ensuing ecological separation promotes sympatry of these two species.

Morphological differences in body shape of two sympatric benthophagous cichlid species from Lake Malawi, Ctenopharynx pictus and an undescribed species, Otopharynx sp. "heterodon nankhumba," were investigated using geometric morphometric methods. From digitized data of landmark points on lateral profiles of fishes. the shape of each species was compared by the thin-plate spline method. Statistical analyses revealed significant variation in both uniform and nonuniform, components of shape between the two species. From the splines generated, it was revealed that most of the significant variation between the two species occurs in the head region. Specifically, C pictus has a longer and deeper head than Otopharynx sp. In addition, the mouth of C pictus is larger than that of Otopharynx sp. In the trunk region, C pictus has a shorter abdominal cavity, which may indicate possession of shorter intestines than Otopharynx sp. The variation in gross head morphology and intestinal length may reflect interspecific differences in trophic ecology, possibly facilitating the coexistence of the two species through resource partitioning.

Interests of stakeholders of international frameworks for conservation and stakeholders of implementation at site level were analysed by using case studies of the East Asia-Australasia Shorebird Site Network implementation in Japan. We found that the interests of local level stakeholders did not match those of national level proponents of the conservation framework. However identification of potential common interests between the two and execution of appropriate campaign strategy by national-level proponents, which targeted at the common interests, brought mutual benefits and helped to achieve goals of the international framework.

Geographical colour variation and distribution of 48 common cichlid fish species were studied at 20 sites along an 85 km shoreline at the southern end of Lake Tanganyika, Africa. Sixteen species had two or more colour morphs and 11 species showed a limited distribution in the study area. They were all rock-dwellers. Distributional borders of the color morphs and species with a limited distribution mostly lay in two long sandy beaches, 7 and 13 km long. We suggest that the long sandy beaches can be effective barriers against dispersal of shallow-water rock-dwelling cichlid fishes.

We conducted a quantitative study of an animal community associated with clumps of submerged drifting algae on a sand/mud bottom at Fildes Bay, King George Island. The algae clumps were found at depths between 5 and 20 m in the inner part of the bay. The clumps mainly consisted of Desmarestia anceps covering about 5% of the bottom. A large number of a nemertinean (0-220 individuals/m^2), Nacella concinna (0-65 individuals/m^2), Glyptonotus antarcticus (adults 0-8 individuals/m^2, juvenile 0-80 individuals/m^2) and gammaridean amphipods (490-25020 individuals/m^2) were found associated with the clumps. Schools of Trematomus newnesi young (0-18 individuals/m^2) hovered over the clumps. Stomach contents of T. newnesi consisted mainly of gammaridean amphipods. The algae clump seemed to be an important habitat as a nursery ground for G. antarcticus and T. newnesi.

Several species of small-sized cichlid fishes inhabit the shell-bed area at Rumonge, Burundi, in the northeastern part of Lake Tanganyika. Some of them are very similar in morphology to the known species occurring in rocky and sandy habitats, but their bodies are unusually small. Investigations of three such small-sized cichlids were made from taxonomic point of view, and it was concluded that they represent small morphs of <I>Altolamprologus compressiceps, Lamprologus callipterus and Neolamprologus mondabu</I>. Their small bodies and some minor morphological differences were interpreted as adaptations to the utilization of empty shells as brooding sites and shelters in the shell-bed environment.

Observations on the reproductive behaviour and polygynous mating system of an endemic shell-brooding cichlid fish, Lamprologus callipterus, revealed that territorial males actively transported and accumulated spawning substrate (empty gastropod shells) to make nests. In contrast to conventional resource defence polygyny, males of this species can therefore create a defensible resource distribution. Females successively visited the nests, chose one shell, spawned the whole clutch inside the shell and stayed inside until the young became independent. Males were freed from direct parental care but defended the territory. Nest usurpation by larger males and frequent shell stealing among males were observed; these resulted in cannibalism of the young fathered by the former males. Large males accumulated more shells and consequently monopolized more females than did smaller males. Maximum size of females was apparently limited by the size of available shells, resulting in extreme sexual dimorphism. Extreme polygyny in this species, associated with intense intra-sexual competition and extreme sexual dimorphism, was based mainly on transportability of spawning substrate and the specific behavioural competence of males to use it.

Four calls of the Leach's Storm-Petrel (<i>Oceanodroma leucorhoa</i>), the Chatter-calls and Purr-calls of both sexes, were played back from a loudspeaker on the ground near the colony in Daikoku Island. All the playback calls attracted birds in flight and elicited Chatter-calls from them. The sex of the attracted birds were judged by analyzing the Chatter-calls. Significantly more birds responded to the playback call of the opposite sex than that of the same sex. It has already been revealed that birds inside burrows respond only to the playback calls of the same sex. Therefore, in this study it was found that the same call can elicit responses from different sexes in different circumstances. Thus, the same call can have different meanings in different contexts.

The vocalizations of a nocturnally active seabird, Leach's Storm-Petrel (<i>Oceanodroma leucorhoa</i>), were studied at their breeding colony on Daikoku Island, Hokkaido, Japan. Three distinct call types were recognized, namely Chatter-call, Purr-call and Screech-call. All were vocalized by both male and female adults. Purr-call vocalizations and those of Screech-calls showed situation-specificities. In the burrows with Purr-call vocalizations, there were two heterosexual birds, but no broods were found. Therefore, this call may be associated with courtship behavior or pair formation. Screech-calls were always vocalized between two consexual birds and seemed to be vocalized during aggressive encounters. Chatter-calls were usually vocalized together with other call types and in various situations, although the aerial birds vocalized only this call type. But situation-specificities were recognized when these situations were divided according to the calls vocalized with Chatter-calls. Some discussion was made about functional interpretation of vocalizations in Leach's Storm-Petrels.

In the siberian chipmunk, a diurnal rodent, a pair of bipolar electrodes were implanted bilaterally near the suprachiasmatic nucleus (SCN). Long-term simultaneous recordings of multiple unit activity (MUA) inside and outside the SCN revealed diurnal rhythms inside the SCN that showed a daytime peak in activity during a 24 h light-dark cycle (LD 12:12). These rhythms persisted during constant darkness. MUA outside the SCN and overt behavior showed circadian rhythms that paralleled MUA inside the SCN. No phase reversal similar to that found in the nocturnal rat was observed. © 1984.
