Dieta de Micoureus demerarae (Thomas) (Mammalia, Didelphidae) associada às florestas contíguas de mangue e terra firme em Bragança, Pará, Brasil

A dieta de Micoureus demerarae (Thomas, 1905) foi estudada em bosques de mangue e terra firme através de amostras estomacais e fecais. O número de indivíduos capturados foi inversamente proporcional à disponibilidade de frutos e insetos, sendo Coleoptera e Hemiptera as ordens de artrópodes mais consumidos e Passifloraceae e Arecaceae os frutos mais ingeridos. Desse modo, tanto a maior variabilidade de frutos como a alta produção destes durante a estação seca, parecem explicar o aumento da captura desses animais nos bosques de terra firme, dos quais são originalmente provenientes. Os itens alimentares sugerem que esta espécie possui uma dieta do tipo onívora, independentemente da sazonalidade ou distribuição dos recursos disponíveis.

Search for a Higgs boson decaying into a Z and a photon in pp collisions at root s=7 and 8 TeV

A search for a Higgs boson decaying into a Z boson and a photon is described. The analysis is performed using proton-proton collision datasets recorded by the CMS detector at the LHC. Events were collected at center-of-mass energies of 7 TeV and 8 TeV, corresponding to integrated luminosities of 5.0 fb(-1) and 19.6 fb(-1), respectively. The selected events are required to have opposite-sign electron or muon pairs. No excess above standard model predictions has been found in the 120-160 GeV mass range and the first limits on the Higgs boson production cross section times the H -> Z gamma branching fraction at the LHC have been derived. The observed at 95% confidence level limits are between about 4 and 25 times the standard model cross section times the branching fraction. For a standard model Higgs boson mass of 125 GeV the expected limit at the 95% confidence level is 10 and the observed limit is 9.5. Models predicting the Higgs boson production cross section times the H -> Z gamma branching fraction to be larger than one order of magnitude of the standard model prediction are excluded for most of the 125-157 GeV mass range.
