SHIPPING INFLUENCE THE LENGTH-WEIGHT RELATIONSHIP AND Paracheirodon axelrodi CONDITION FACTOR (CHARACIDAE)

Foi comparada a relação peso-comprimento (RPC) e fator de condição relativo (Kn) de Paracheirodon axelrodi de habitat natural após sua captura e transporte, simulando fielmente algumas etapas do processo de extração de peixes ornamentais amazônicos. Os peixes foram divididos aleatoriamente em dois grupos: habitat natural (pré-transporte) e após a captura e transporte (pós-transporte). Em cada grupo foram medidos a massa corporal (Wt) e comprimentou total (Lt) para determinação da RPC e Kn em diferentes faixas de tamanho.A RPC do grupo pré-transporte foi Wt = 0,014Lt2,528 (r2 = 0,966) e grupo pós-transporte foi Wt = 0,010 Lt2,848 (r2 = 0,956). Ambos os grupos apresentaram alometria negativa e houve diferença entre o valor de b entre grupos estudados. As médias do peso real dos peixes e Kn foram menores no grupo pós-transporte. Os resultados demonstram que o pós-transporte é uma etapa crítica na cadeia extrativista de P. axelrodi devido às baixas condições corporais dos peixes indicada pela RPC e Kn. Portanto, indicam a necessidade melhoria das técnicas de manejo na cadeia de extração desse peixe ornamental amazônico.Palavras-chave: Crescimento alométrico, cardinal, peixe ornamental, estresse, transporte.Length–weight relationship (LWR) and relative condition factor (Kn) of wild Paracheirodon axelrodi after caught and simulated transport were investigated. These fish were random distributed in two groups: wild fish (pre-transport) and after caught (post- transport). For each group the body weight and total length were measured to determination from LWR and Kn. The LWR of fish in pre-transport was Wt = 0.014Lt2.528 (r2 = 0.966) and in post-transport was Wt = 0.010 Lt2.848 (r2 = 0.956). Both groups had a negative allometric growth and differences between values of b (p<0.001) were observed. Body weight of fish and Kn were lower during post-transport.  Results demonstrated that post-transport is crucial phase in the extractives fishery from P. axelrodi, due to poor body conditions of the fish, which was indicated by the LWR and Kn. Therefore, they indicates the necessity of improve in the management techniques during and after the caught of this ornamental fish from Amazonian.Keywords: Allometric growth, cardinal, ornamental fish, stress, transport.

Prevalence of human papillomavirus infection among women from quilombo communities in northeastern Brazil

Abstract Background Human papillomavirus (HPV) is a member of the Papillomaviridae family. The prevalence of HPV genotypes may vary according to the region and the population studied. Quilombo communities are ethnic and racial groups with difficult access to health services compared to the general population in Brazil. The aim of this study was to identify specific HPV types correlating with sociodemographic/behavioral characteristics and cervical smear cytological abnormalities in Quilombola women. Methods This cross-sectional study included 395 Quilombola women users of the Unified Health System of the Municipalities of Maranhão for the screening of cervical cancer. The samples were analyzed for the presence of cytological abnormalities by conventional methods and tested for 37 HPV genotypes using polymerase chain reaction with primers PGMY09/11 followed by reverse line blot hybridization performed with the Linear Array HPV Genotyping Test kit by Roche Molecular System®. The association between HPV types and cytological diagnosis was investigated according to the different age groups. Results HPV infection was detected in 12.6% (50/395) of the women. Infections by high-risk HPV types were more frequent. Genotypes 68 (26.0%); 58 and 52 (20.0%); 31 (10.0%) and 62 (8.0%) were the most prevalent. The highest prevalence (42.0%) of HPV infection occurred in women diagnosed with high-grade squamous intraepithelial lesion. There was a statistically significant association between HPV infection and the detection of cytological abnormalities in all age groups except in women over 60 years. There was a statistically significant association between the municipality of origin and the number of partners with HPV infection. Conclusions It is important to incorporate new cervical cancer screening techniques incorporating the cervical-vaginal cytology. For further studies, it is necessary to determine the level of knowledge of Quilombola population on health-related issues including HPV infection and cervical cancer. This will contribute to the continuous improvement of healthcare coverage among the population and enhance the implementation of cancer care in the state of Maranhão

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
