Spatial-temporal variation of parasites in Cnemidophorus ocellifer (Teiidae) and Tropidurus hispidus and Tropidurus semitaeniatus (Tropiduridae) from Caatinga areas in northeastern Brazil
(Parasitology Research, 2014-03-01) [Artigo]
Parasites are natural regulators of their host populations. Despite this, little is known about variations in parasite composition (spatially or temporally) in environments subjected to water-related periodic stress such ...
Serology, isolation, and molecular detection of Leptospira spp. from the tissues and blood of rats captured in a wild animal preservation centre in Brazil
(Preventive Veterinary Medicine, 2014-07-01) [Artigo]
To elucidate the occurrence and epidemiology of leptospirosis in rats cohabitating with forest animals, 13 rats were captured at seven locations of the Centre for the Conservation of Wild Fauna (CCWF) in Sao Paulo state, ...
Thermal equilibrium responses in Guzerat cattle raised under tropical conditions
(Journal Of Thermal Biology, 2016-08-01) [Artigo]
The literature is very sparse regarding research on the thermal equilibrium in Guzerat cattle (Bos indicus) under field conditions. Some factors can modify the physiological response of Guzerat cattle, such as the reactivity ...
Fluid dynamic study of mixtures of sugarcane bagasse and sand particles: Minimum fluidization velocity
(Biomass and Bioenergy, 2017-01-01) [Artigo]
This paper is focused on the study of fluid-dynamic behavior of mixtures of the sugarcane bagasse particles and quartz sand in a transparent fluidized bed column. The minimum fluidization velocity (Vmf) was determined by ...
Prediction of the minimum fluidization velocity of particles of sugarcane bagasse
(Biomass and Bioenergy, 2018-02-01) [Artigo]
This study refers to an experimental analysis of the fluid-dynamics of particles of sugarcane bagasse in a fluidization column with an internal diameter of 190 mm, which determined the minimum fluidization velocity of the ...
Evidence for heterochrony in the cranial evolution of fossil crocodyliforms
(Palaeontology, 2018-07-01) [Artigo]
The southern supercontinent of Gondwana was home to an extraordinary diversity of stem-crocodylians (Crocodyliformes) during the Late Cretaceous. The remarkable morphological disparity of notosuchian crocodyliforms indicates ...
Ovicidal and larvicidal activity of extracts of Opuntia ficus-indica against gastrointestinal nematodes of naturally infected sheep
(Veterinary Parasitology, 2016-08-15) [Artigo]
This study describes the in vitro anthelmintic activity of extracts from Opuntia ficus indica against gastrointestinal nematodes of sheep. The anthelmintic activity was evaluated by inhibition of egg hatching, larval ...
Gastrointestinal nematodes of the lizard Tropidurus hispidus (Squamata: Tropiduridae) from a semi-arid region of north-eastern Brazil
(Journal of Helminthology, 2013-12-01) [Artigo]
The tropidurid lizard Tropidurus hispidus has a wide distribution in South America. However, knowledge about its helminth fauna is patchy and has been reported for only a few localities along its range of distribution. ...
Occurrence of Strongyluris oscari (Nematoda; Heterakidae) in Enyalius bilineatus (Squamata: Leiosaurinae) from the Brazilian Atlantic Forest
(Herpetology Notes, 2014) [Artigo]
Straw decomposition of nitrogen-fertilized grasses intercropped with irrigated maize in an integrated crop-livestock system
(Revista Brasileira de Ciência do Solo, 2011-12-01) [Artigo]
A maior limitação para a sustentabilidade do sistema plantio direto no Cerrado é a pequena deposição e a rápida decomposição da palhada na superfície do solo entre o outono e a primavera, em razão dos déficits hídricos e ...
