Release of potassium from rock powder by the yeast Torulaspora globosa

The alteration of minerals in rocks and the availability of elements for plant nutrition require long periods of time, and microorganisms are thought to induce the release of potassium and phosphate from rocks. In this context, this work evaluates the role of the yeast Torulaspora globosa, isolated from the sugar cane rhizosphere, in the solubilization of potassium from alkaline ultramafic rock powder. The experiments were performed in liquid medium, with or without agitation, at 30°C with the following treatments: culture medium + alkaline ultramafic; culture medium + yeast suspension; and culture medium + yeast suspension + alkaline ultramafic. The results showed that as much as 38% of the total potassium in the rock was released in the medium with the yeast during a 15-day period of incubation. Acid production may be the mechanism by which the yeast solubilizes potassium because the total acidity increased during the sampling period. Agitation (which increased oxygen availability) resulted in approximately 20% more biosolubilization of the alkaline ultramafic rock than with the static culture. These data indicate the potential for this yeast in biosolubilization processes and biofertilizer production.

The diet of bats from Southeastern Brazil: the relation to echolocation and foraging behaviour

In this study the incidence of moths and beetles was examined from feces samples of bats that use different foraging behaviors. Twenty sites around the Fazenda Intervales, a Field Research Station located in São Paulo State, in southeastern Brazil were sampled. Feces were collected from bats caught in mist nets, Turtle Traps or hand nets and, in one case, from beneath a roost. Feces samples were taken from six species of bats: Micronycteris megalotis (Gray, 1842), Mimon bennettii (Gray, 1838), Furipterus horrens (F. Cuvier, 1828), Myotis riparius Handley, 1960, Myotis ruber (E. Geoffroy, 1806) and Histiotus velalus (I. Geoffroy, 1824). To record and describe the frequencies dominating bat echolocation calls, an Anabat II bat detector coupled with an Anabat ZCA interfaces and DOS laptop computers were used. The data show that Furipterus horrens feeds extensively on moths, as predicted from the features of its echolocation calls. Gleaning bats, whose echolocation calls are much less conspicuous to moths take a wide range of insect (and other) prey.

Abundance, habitat use and diet of Callicebus nigrifrons Spix (Primates, Pitheciidae) in Cantareira State Park, São Paulo, Brazil

Entre abril de 2005 e maio de 2006, através de censos seguindo os pressupostos da metodologia de transecção linear, foram estimadas a densidade populacional e abundância de Callicebus nigrifrons Spix, 1823 (Pitheciidae) no Parque Estadual da Cantareira, Estado de São Paulo, Sudeste do Brasil (23°23'42S, 46°35'27W). Com um esforço amostral de 275,8 km de censos, os sauás foram a segunda espécie de primata mais abundante, apresentando um índice de abundância de 1,4 grupos para cada 10 km percorridos e uma estimativa de densidade de 12,21 ind./km² (variando de 8,45 a 17,63 ind./km²). A coleta de dados auxiliares durante os censos possibilitou a verificação da dieta e uso do hábitat pelos grupos de Callicebus, e os resultados evidenciaram uma relativa adaptabilidade à ambientes perturbados.

A Hypercaloric pellet-diet cycle induces obesity and co-morbidities in wistar rats

O objetivo do estudo foi desenvolver um ciclo de dietas hipercalóricas para promover obesidade em ratos. Ratos Wistar foram distribuídos em dois grupos: dieta normal (ND = 32; 3,5 kcal/g) e dietas hipercalóricas (HD; n = 32; 4,6 kcal/g). O grupo ND recebeu ração comercial e os animais HD um ciclo de diferentes dietas hipercalóricas, por 14 semanas. As variáveis analisadas foram peso corporal, parâmetros metabólicos e hormonais, pressão arterial sistólica e teste oral de tolerância à glicose. O nível de significância foi de 5%. O ciclo de dietas hipercalóricas promoveu aumento de peso e gordura corporal, pressão arterial sistólica e níveis séricos de glicose, triacilglicerol, insulina e leptina no grupo HD. Além disso, o grupo HD apresentou tolerância à glicose diminuída. em conclusão, os resultados deste estudo mostram que o ciclo de dietas hipercalóricas promove obesidade e exibe várias características comumente associadas com a obesidade humana, como aumento da pressão arterial, resistência à insulina, hiperglicemia, hiperinsulinemia, hiperleptinemia e dislipidemia.
