An opportunity for testing multiple paternity in a wild Jaguar (Panthera onca) Biota Neotropica
Pinho,Gabriela Medeiros de; Fonseca,Rogerio; Farias,Izeni Pires.
We performed a paternity test for three cubs from one wild female jaguar (Panthera onca). The opportunity for this study was generated by an accident involving a vehicle collision with a pregnant jaguar in the central Amazon. The cubs are polyzygotic triplets and were found to have been sired by the same male. Here, we also provide an overview and discuss several aspects of jaguar reproduction.

Evidence of polygamy in the socially monogamous Amazonian fish Arapaima gigas (Schinz, 1822) (Osteoglossiformes, Arapaimidae) Neotropical Ichthyology
Farias,Izeni Pires; Leão,Adam; Almeida,Yane Santos; Verba,Júlia Tovar; Crossa M.,Marcelo; Honczaryk,Alexandre; Hrbek,Tomas.
Arapaima gigas is one of the largest freshwater fishes of the world. It is socially monogamous, forming pairs, constructing a nest and providing parental care. We performed a paternity analysis under three scenarios in captive, semi-natural and natural areas using 10 microsatellite markers. As a positive control, we analyzed three pairs and their offspring isolated individually in artificial breeding ponds (a priori very high probability of monogamy). We then analyzed two samples of offspring from large artificial ponds with multiple adults but only one reproductive pair (a priori high probability of monogamy), two samples from semi-natural breeding station with multiple adults but only one reproductive pair (a priori high probability of monogamy), and a...
