Damage in Khaya ivorensis caused by Trigona spinipes in Brazilian savannah

Acta Brasiliensis, 2017
Trigona spinipes (Dog bee) attack the apical bud of Khaya ivorensis causing atrophy and budding which provoke branches that will depreciate the shaft if not handled. Damage to the culture of K. ivorensis has been reported for Brazil, but never before for

Sequential Bayesian approach for genetic diversity analysis of the piracanjuba fish (Brycon orbignyanus)

Brazilian Journal of Biometrics
In the sequential Bayesian approach, the sample size is not fixed before the experiment; it is determined based on the observations made. The procedure concludes when there is enough information to estimate the parameters, according to a stopping criterion.
