| Engorged and partially engorged females of Boophilus microplus were exposed to 600; 3,000; 6,000 and 30,000 infective juveniles of Steinernema carpocapsae Weiser, 1955 Santa Rosa and All strains per dish, under lab conditions. Eggs weight, pre-laying period, laying period, survival period, reproductive efficiency rate, percentage of larval eclosion and lethal concentrations of 50% and 90% (CL50 and CL90) were calculated for engorged females. In the case of partially engorged females, only egg weight, survival period and CL50 and CL90 were calculated. All biological parameters of engorged or partially engorged females were altered by exposition of S. carpocapsae infective juveniles (IJs), Santa Rosa and All strains (p<0.05). The increase in the response... |

| A Zona da Mata Mineira está localizada no sudeste do estado de Minas Gerais, nos domínios da Mata Atlântica, e é uma região altamente fragmentada, com muitas manchas pequenas e isoladas, cuja avifauna é pouco estudada. O objetivo deste trabalho foi inventariar a avifauna da Reserva Biológica Municipal Poço D'Anta (277 ha), uma área de floresta do município de Juiz de Fora, sudeste de Minas Gerais, através da caracterização de alguns aspectos ecológicos e o status de conservação. O levantamento foi realizado entre os períodos de março a setembro de 2007, e março de 2008 a maio de 2009, utilizando a lista de Mackinnon, capturas com redes-de-neblina e observações ocasionais. Foram identificadas 156 espécies, das quais 44 (28%) são endêmicas da Mata Atlântica... |

| The nervous and endocrine systems jointly control intestinal movements, secretions of their glands and also participate of the processes of nutrient digestion and absorption. Therefore, the central objective of this study was to verify the existence of a possible relationship between the number of nervous cells and ganglia of the submucosal and myenteric plexuses and the number of endocrine cells in the small intestine of adult D. aurita. The utilized staining techniques were Grimelius, modified Masson-Fontana, direct immunoperoxidase and H-E. Argyrophillic, argentaffin and insulin immunoreactive endocrine cells do not numerically vary between the initial, mid and final regions of the duodenum, jejunum and ileum (P>0.05), except for argyrophillic cells... |

| Since the campus of the Federal University of Juiz de Fora, Minas Gerais State, Brazil, has different landscapes, it turns up to be a useful ecological model to evaluate the influence of habitat heterogeneity on bird communities. Our research goals were to know the local avifauna and compare its composition and bird diversity within the different landscapes. Species were identified in point counts without distance estimation, in four habitats: secondary woodlot, lake and surroundings, scrub/abandoned grazing areas and urban areas. One hundred and twenty-one species were identified, but no difference in diversity among the habitats was found. However, analyses indicated the existence of greater similarities among the sampling points belonging to the same... |
