With the present study, we investigat ed the interaction and knowledge of the inhabitants about the biology of Sapajus flavius. Data were obtained through structured questionnaires and semi-structured and free interviews with local communities living on the banks of two fragments of Atlantic Forest important for the conservation of S. flavius, Camaratuba Experimental Station / ASPLAN and Pau Brasil State Ecological Station, in the municipality of Mamanguape, PB. Through questionnaires applied to the residents about the blond capuchin monkey, information was obtained on the ecology and attitudes of the interviewees in relation to their conservation. Subsequently, Local Ecological Knowledge Indicators (LEK) and Conservation Attitudes were developed for residents. The results show that the inhabitants' contact with the forest brings experience about the biology of the blond capuchin monkey to them, and thus, they have knowledge regarding mainly their diet. Residents interviewed stated that the blond capuchin monkey have been decreasing in forest fragments over the years, and that possibly the main reason is the reduction of the availability of resources and the increase of antropic activities in the areas. Most of the residents have a high index of local ecological knowledge about the blond capuchi n monkey, although the information is distributed differently between men and women and according to age, with older men having a higher index of knowledge. Likewise, the presence of existing conflicts from the invasion of monkeys to the plantations of the residents did not affect their conservation attitude, and the interviewees showed a high predisposition to conserve the species. These results lead us to consider that the blond capuchin monkey is seen as a charismatic species, arousing the inhabitants' interest in knowing the species, and, above all, conserving it / A sobreposição ecológica de humanos e demais primatas através da antropização acaba proporcionando interações diversas entre esses grupos animais, algumas de caráter harmonioso e outras gerando conflitos entre os mesmos, prejudicando, assim, o estado de conservação das espécies silvestres envolvidas. Com o presente estudo, investigamos a interação e conhecimentos dos moradores sobre a biologia de Sapajus flavius. Os dados foram obtidos através de questionários estruturados e entrevistas semiestruturadas e livres com comunidades locais que vivem às margens de dois fragmentos de Floresta Atlântica importantes para a conservação de S. flavius, Estação Experimental de Camaratuba/ASPLAN e Estação Ecológica Estadual Pau Brasil, no município de Mamanguape, PB. Através de questionários aplicados aos moradores a respeito dos macacos-prego-galegos, foram obtidas informações sobre a ecologia e atitudes dos entrevistados com relação à conservação dos mesmos. Posteriormente foram elaborados Indicadores de Conhecimento Ecológico Local (CEL) e de Atitudes de Conservação para os moradores. Os resultados mostram que o contato dos moradores com a mata traz experiência sobre a biologia do macaco-prego-galego aos mesmos, e assim, eles possuem conhecimento no que diz respeito principalmente à sua dieta. Os moradores entrevistados afirmaram que os macacos-prego-galegos vêm diminuindo nos fragmentos de mata ao longo dos anos, e que possivelmente o motivo principal seja a redução da disponibilidade de recursos e o aumento de atividades antrópicas nas áreas. A maior parte dos moradores possui alto índice de conhecimento ecológico local sobre o macaco -prego- galego, embora as informações sejam distribuídas diferentemente entre homens e mulheres e conforme a idade, com os homens mais velhos possuindo maior índice de conhecimento. Da mesma forma, a presença de conflitos existente oriundos das invasões dos macacos às plantações dos moradores não afetou a atitude de conservação dos mesmos, e os entrevistados apresentaram alta predisposição em conservar a espécie. Esses resultados nos levam a considerar que o macaco-prego-galego é visto como uma espécie carismática, despertando o interesse dos moradores em conhecer a espécie, e, sobretudo a conservá-la.

Body colouration in tilapia is an important trait affecting consumer preference. In the Nile tilapia (Oreochromis niloticus), there are three colour variants which are normal (wild type), red and blond. In some countries, the red variant is important and reaches higher prices in the market. However, one major problem regarding red tilapia culture is their body colouration which is often associated with blotching (mainly black but also red) which is undesirable for the consumer. The overall aim of this work was to expand knowledge on various aspects of body colouration in Nile tilapia using genetic approaches. The results of this research are presented as four different manuscripts. The manuscripts (here referred as Papers) have either been published (Paper IV) or are to be submitted (Paper I, II and III) in relevant peer reviewed journals. Paper I and II investigated the inheritance of black blotching and other body colour components of the red body colour. Specifically, Paper I consisted of two preliminary trials (Trial 1 and 2), to look at the ontogeny of black blotching and body colour components over a period of six months. Trial 1 investigated the effect of tank background colour (light vs dark) on black blotching and other body colour components and was carried out using a fully inbred (all female) clonal red line. Trial 2 was carried out using mixed sex fish and was aimed to investigate the association of black blotching with the sex of the fish. The results from this study were used to guide the experiment described in Paper II. Sixteen red sires with various levels of black and red blotching were crossed to clonal females and the inheritance of blotching and other body colour components were investigated using parent-offspring regressions. The results showed no significant heritability for black blotching and body redness, but a significant correlation for body redness and black blotching was found in female offspring at one sampling point suggesting that attempts to increase body redness may increase black blotching, as had been hypothesized. Paper III was divided into two parts. The first objective was to map the blond locus onto the tilapia linkage map and the second was to investigate the interaction of the blond and red genes on black blotching using the blond-linked markers to distinguish different blond genotypes in heterozygous red fish (i.e. RrBlbl or Rrblbl). In the blond fish, the formation of melanin is almost blocked via much reduced melanophores and this feature may be able to help reducing the black blotching in red tilapia. Two intraspecific families (O. niloticus) and one interspecific family (O. aureus and O. niloticus) were used as mapping families and the blond locus was located in LG5. Four out of eight markers were successfully used to assess the interaction of blond on red blotched fish. The blond gene did not significantly reduce the area of blotching but did reduce the saturation (paler blotching) and enhanced the redness of body colour in the Rrblbl fish compared to the RrBlbl group. Finally, Paper IV aimed to find out the effect of male colouration on reproductive success in Nile tilapia. A choice of one wild type male and one red male was presented to red or wild type females and these fish were allowed to spawn under semi-natural spawning conditions. Eggs were collected from the female’s mouth after spawning and paternity was assessed using microsatellite genotyping and phenotype scoring. No significant departures from equal mating success were observed between the red and wild type males, however there was a significant difference between the red and wild type females in the frequency of secondary paternal contribution to egg batches. The results suggest that mating success of wild type and red tilapia is approximately equal. The results from this research help to broaden our knowledge and understanding on the aspects of body colouration in Nile tilapia and provide fundamental information for further research.
