Thylamys pallidior (O. Thomas, 1902) is a didelphid marsupial commonly called the white-bellied fat-tailed mouse opossum. A small mouse opossum, with tricolored pelage and a white venter, it has a seasonally incrassated tail, where fat deposits, primarily at the tail base, function in food storage. It is the most widely distributed species in the genus occurring from southwestern Peru and north...

The Roach’s Mouse-tailed Dormouse ( Myomimus roachi , Bate 1937) is endemic to the Western Palearctic (occurring in SE Bulgaria, Turkish and Greek Thrace, western Anatolia) one of less known mammals within region. There no information about its biology ecology wild. In course past 3 years (2019-2021), we conducted intensive research on a small population situated southeast Bulgaria (Sakar mount...

Asymmetric volatility refers to the stylized fact that stock volatility is negatively correlated to stock returns. Traditionally, this phenomenon has been explained by the financial leverage effect. This explanation has recently been challenged in favor of a risk premium based explanation. We develop a new, unlevering approach to document how well financial leverage, rather than size, beta, boo...

Controlling for idiosyncratic volatility, large stocks earn higher returns than small stocks. Idiosyncratic volatility is positively related to return, but negatively related to size. Failure to control for idiosyncratic volatility generates a downward omitted variable bias, leading to the widely documented negative size-return relation. We explain the two contrasting sizereturn relations in a ...

despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

Although commonly associated with infection in cattle, bovine viral diarrhea viruses (BVDV) also replicate in many domestic and wildlife species, including cervids. Bovine viral diarrhea viruses have been isolated from a number of cervids, including mule deer (Odocoileus hemionus), European roe deer (Capreolus capreolus), red deer (Cervus elaphus), white-tailed deer (Odocoileus virginianus), an...

Most of our understanding of forebrain development comes from research of eutherian mammals, such as rodents, primates, and carnivores. However, as the cerebral cortex forms largely prenatally, observation and manipulation of its development has required invasive and/or ex vivo procedures. Marsupials, on the other hand, are born at comparatively earlier stages of development and most events of ...
