Resumo: | A marine biological invasion is a natural process accelerated by human activities, and the crab Charybdis hellerii is an example of a globally widespread invasive species. This study evaluated color variation in C. hellerii and its relationship to the sex, size and sexual maturity of these crabs, and compared the efficiency of a freeware digital image-editing program with a commercially available program. The color of the individuals was analyzed using standardized digital images. The color pattern varied significantly with size; smaller and immature individuals were darker than larger and mature ones. The female abdomen changed in morphology and color with sexual maturity, becoming wider and orange-colored. There was no statistical difference in the color values between males and females and immature males did not show morphological or color differences in their abdomen. This study highlights the possible relationships of the color and physiological state of the reproductive system, which could help in future studies of behavior, avoiding the need to dissect and/or remove individuals from nature for assessment of sexual maturity. The freeware program showed the same efficiency in digital image analysis as a widely known commercial program. |

Este estudo avaliou a variação de cor em C. hellerii e sua relação com o sexo, tamanho e maturidade sexual desses indivíduos, e comparou a eficiência de um programa de edição de imagem de licença livre com um programa disponível comercialmente. A cor dos indivíduos foi analisada usando imagem digital padronizada. O padrão de cor variou significantemente com o tamanho; indivíduos pequenos e imaturos são mais escuros que indivíduos maiores e maduros. Os abdomens das fêmeas mudaram morfologicamente e na cor de acordo com a maturidade sexual, tornando-se mais largos e de cor alaranjada. Não houve diferença estatística nos valores de cor entre machos e fêmeas, e machos imaturos não mostraram diferenças morfológicas e de cor em seus abdomens. Este estudo ressalta as possíveis relações da cor e estado fisiológico do sistema reprodutivo o que pode ajudar futuramente em estudos comportamentais, evitando a necessidade de dissecar e/ou remover indivíduos da natureza para avaliar a maturidade sexual. O programa livre obteve a mesma eficiência na análise de imagem digital em relação ao programa comercial amplamente conhecido.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Federal do Amazonas (UFAM), Programa de Pós-Graduação em Ciência e Tecnologia para Recursos Amazônicos (PPGCTRA), Instituto de Ciências Exatas e Tecnologia (ICET), Rua Nossa Senhora do Rosário, 3863, 69103-128 Itacoatiara, AM, BrasilUniversidade Estadual Paulista (UNESP), Faculdade de Ciências Agrárias e Veterinárias, Centro de Aquicultura, Instituto de Estudos Avançados do Mar, Departamento de Biologia Aplicada, Laboratório de Morfologia de Invertebrados, Campus de Jaboticabal, Via de Acesso Prof. Paulo Donato Castellane, s/n, 14884-900 Jaboticabal, SP, BrasilUniversidade de São Paulo (USP), Instituto Oceanográfico (IOUSP), Departamento de Oceanografia Biológica (DOB), Praça do Oceanográfico, 191, 05508-120 São Paulo, SP, BrasilUniversidade Estadual Paulista (UNESP), Faculdade de Ciências Agrárias e Veterinárias, Centro de Aquicultura, Instituto de Estudos Avançados do Mar, Departamento de Biologia Aplicada, Laboratório de Morfologia de Invertebrados, Campus de Jaboticabal, Via de Acesso Prof. Paulo Donato Castellane, s/n, 14884-900 Jaboticabal, SP, BrasilCNPq: 301240/2006-0CNPq: 308215/2010-9FAPESP: 2005/04707-5FAPESP: 2010/50188-8Academia Brasileira de CiênciasUniversidade Federal do Amazonas (UFAM)Universidade Estadual Paulista (Unesp)Universidade de São Paulo (USP)Watanabe, Timoteo T.Zara, Fernando J.
