Crop–livestock integrated production systems (CLISs) combine cash-crop and forage in succession. There are plenty of options cultivars with differences aspects seeds cost, there is little information on how the choice cultivar can affect results a CLIS. We hypothesized that different have important economic impacts systems. Thus, we evaluated two-year using three species CLIS: (1) Urochloa ruzi...

In two fruit fly species, in vivo observations of competing sperm reveal how differences in sperm size, female behavior and reproductive architecture promote retention of same-species sperm. Sexual selection continues after mating and may play an important role in speciation.

During the past 15 years many new pasture species and cultivars have been released and are now commercially available. However, with the exception of Nui and Ellett ryegrasses, only a few have received enthusiastic acceptance by farmers. Acceptance depends in part to the extent to which the new plant can overcome periods of low productivity. Other reasons which are the frequent subject of comme...

sepsis is a significant cause of morbidity and mortality in neonates. the most common pathogens of bacterial sepsis and antibiotic sensitivity patterns vary in different parts of the world. the aim of this study was to determine the most common pathogens and outcome of neonatal sepsis and also antibiotic sensitivity patterns of klebsiella species. a retrospective descriptive study was carried o...

the present study aimed to assess pure planted species (i.e., alnus subcordata l., poplus deltoids l., taxadium distichum l. rich) and a mixed natural forest (i.e., dominated by quercus castaneifolia c. a. mey. - carpinus betulus l. - parrotia persica c. a. meyer) on basis of some soil quality indices in mazandaran province, northern iran. sixteen samples per stand were taken from the top 10 cm...

The responses of termite species to bait depend upon the quality of the food used in the stations. Woods are the most common food sources for termites but different termite species behave differently to different wood species and types. The knowledge of the preference status of different wood species to a termite species helps in effective monitoring and baiting program. The current study was c...

There is growing appreciation that social decision making in humans is strongly influenced by hedonic and emotional processing. The field of social neuroeconomics has shown that neural systems important for reward are associated with social choice and social preferences in humans. Here, we show that the neurobiology of social preferences in a monogamous rodent species, the prairie vole, is also...
