The study of fish population structure is one strategy to know the condition of fish population and water pollution level in a waters area. Guppy fish (Poecilia reticulata Peters) can live in various conditions of water quality, especially in rivers. The Gajah Putih River flowing through Surakarta, Central Java is the habitat of guppy fish. The number of residential and factory activities that dump waste into the Gajah Putih River, causing a decrease in river water quality. Research on the population structure of Guppy fish in Gajah Putih river, Surakarta City was conducted between September and December 2014. Sampling was done purposively where the Guppy fish was found. There are 10 locations along the Gajah Putih River for sampling, each 300m away. At each location, a random sample of 30 fish was collected, then sorted by age and sex. There are also measurements of energy reserves in fish samples, as well as physical and chemical factors of water. Based on temperature, DO, pH TS and COD, the environmental conditions of the Gajah Putih River waters can still be tolerated by Guppy fish. The difference of environmental parameters between stations is relatively small, so it does not affect the difference of population structure of Guppy fish between stations.

Abstract:
Abstract Genetic and physical mapping of the guppy (Poecilia reticulata) have shown that recombination patterns differ greatly between males and females. Crossover events occur evenly across the chromosomes in females, but in male meiosis they are restricted to the tip furthest from the centromere of each chromosome, creating very high recombination rates per megabase, as in pseudoautosomal regions of mammalian sex chromosomes. We used GC content to indirectly infer recombination patterns on guppy chromosomes, based on evidence that recombination is associated with GC-biased gene conversion, so that genome regions with high recombination rates should be detectable by high GC content. We used intron sequences and third positions of codons to make comparisons between sequences that are matched, as far as possible, and are all probably under weak selection. Almost all guppy chromosomes, including the sex chromosome (LG12), have very high GC values near their assembly ends, suggesting high recombination rates due to strong crossover localization in male meiosis. Our test does not suggest that the guppy XY pair has stronger crossover localization than the autosomes, or than the homologous chromosome in the close relative, the platyfish (Xiphophorus maculatus). We therefore conclude that the guppy XY pair has not recently undergone an evolutionary change to a different recombination pattern, or reduced its crossover rate, but that the guppy evolved Y-linkage due to acquiring a male-determining factor that also conferred the male crossover pattern. We also identify the centromere ends of guppy chromosomes, which were not determined in the genome assembly.

Abstract:
The guppy Poecilia reticulata has proven a model species for behavioural ecology; in this thesis, its patterns of group-living were examined in a variety of contexts. These fish engage in inspection, the risky approaching of a predator to gain information on the threat posed. To lessen this risk, guppies may cooperate by approaching together, taking it in turns to advance. The temptation is for fish to defect by holding back and observing the inspection of others, gaining information at their partner's expense. Theory predicts that individuals should associate with those that have been previously cooperative in order to avoid being defected against. To test this, I quantified the social networks of wild-caught female shoals of guppies and then exposed them to a pike cichlid predator Crenicichla frenata. Guppies that inspected together frequently were both more cooperative and more associated in the network than infrequently inspecting partners. Simulating defection by preventing some fish inspecting. in similar female shoals, I found, contrary to predictions, that there was no change in the preference of others. to partner with them afterwards. Guppies appear to assort with respect to cooperation but not reassort in response to defection. Additional experiments found that the number of fish, and thus the number of partners to choose from, did not change how cooperative fish were during inspection, perhaps because of consistent partner choice. I then examined if these stable partnerships observed in the laboratory occurred in the much larger social networks seen in the wild. I found that female guppies of similar inspection tendencies interacted more often than predicted by random models. If guppies prefer shoaling with particular individuals over others, they may learn preferentially from others also. Testing shoals of domestic female guppies in a novel foraging task, naIve guppies performed the task fas~er when a trained fish was highly connected to them in their social network. However, if there were two trained fish with conflicting tasks, then they performed the task of the less connected fish faster. The network position of trained fish appears to impact upon the potential for social learning of naIve fish but other factors, e.g. the competitive ability of the trained fish, may influence how naIve fish act on that information. Thus we see that the benefits to a fish of shoaling with others depend upon the shoaling partners chosen and that guppies exercise this choice with care in a number of contexts.

Abstract:
Many studies of evolution adopt a unifactorial approach, where a single causal force appearing to account for a majority of the phenotypic variation becomes the focal point of investigation. However, it seems certain that no single force acts to the complete exclusion of other forces, and so multi-factorial studies can make a crucial contribution to our understanding of the evolution of phenotypic variation. In the Trinidadian guppy system, natural selection acting via predation has long been recognized as playing an important role in shaping trait variation. However, other environmental factors also likely contribute, and my thesis explores the potential role of one of them: parasitism. I specifically focus on Gyrodactylus, a monogenean ectoparasite that has important effects on many fish species and coexists with guppies in the wild. I evaluate the extent to which parasitism varies among guppy populations, particularly in relation to predation. I then ask whether parasitism influences phenotypic variation in guppy traits. This work was executed through a large-scale survey in northern Trinidad, where 26 guppy populations of known predation level (high or low) were surveyed across 10 different rivers. Individual guppies were scanned for Gyrodactylus and then photographed for image analyses aimed at quantifying body size and aspects of male colour. I found that among-population variation in parasitism levels was consistent between two dry seasons, and that high-predation localities tend to have higher levels of parasitism than do low-predation localities. However, I found few effects of parasitism on guppy traits and no major modifying influence of parasitism on inferences about the role of predation. Although more work certainly needs to be done with respect to parasitism, our results suggest it might be more profitable to concentrate on other potential causal factors that shape guppy trait variation.
De nombreuses études sur l'évolution adoptent une approche uni-factorielle qui se concentrent sur une seule force pouvant expliquer la plupart de la variation phénotypique observée. Cependant, il est évident qu'aucune force n'exerce son effet de façon isolée. C'est pourquoi les études multi-factorielles apportent une contribution cruciale à notre compréhension de l'évolution de la variation phénotypique. Dans le système d'étude des guppies de Trinité, la sélection naturelle imposée par les prédateurs a depuis longtemps été considérée comme un facteur important dans l'élaboration de la variation au niveau des traits. Cependant, d'autres facteurs environnementaux contribuent également à cette élaboration, notamment le parasitisme. Je me penche sur le rôle potentiel que peuvent avoir les parasites du genre Gyrodactylus sur les traits des guppies. Ces ectoparasites monogènes exercent de nombreux effets sur plusieurs espèces de poissons et coexistent avec les guppies dans leur environnement naturel. J'évalue le niveau de variation du parasitisme entre les populations de guppies, et plus spécifiquement en relation avec la prédation. J'explore par la suite l'influence potentielle du parasitisme sur la variation phénotypique des traits des guppies. Pour ce faire, une étude de grande échelle a été effectuée sur 10 rivières dans le nord de Trinité, dans laquelle 26 populations sujettes à des niveaux de prédation connus (élevé ou bas) ont été inventoriées. L'état d'infection par les Gyrodactylus a été répertorié pour chaque guppy, puis les poissons ont été photographiés pour analyser les images dans le but de quantifier la taille corporelle ainsi que de nombreux aspects de la coloration chez les mâles. J'ai trouvé que les niveaux de parasitisme entre les populations étaient consistants entre les deux saisons sèches recensées, et qu'il y a une tendance pour les sites de haute prédation à avoir des niveaux de parasitisme plus élevés que les sites de basse prédation. Cependant, j'ai trouvé que la parasitisme avait peu d'effets sur les traits des guppies et aucune influence majeure n'a été trouvée sur les inférences concernant la prédation. Bien qu'il reste encore beaucoup de travail à faire en ce qui a trait au parasitisme, nos résultats suggèrent qu'il pourrait être plus profitable de se concentrer sur d'autres facteurs potentiels pouvant expliquer la variation de traits chez les guppies.
