The Ricardo Group is a 1,700-m-thick sequence of Miocene volcanic rocks and continental sedimentary rocks deposited between ~19 and 7 Ma in the El Paso basin, near the junction of the Garlock fault and the Sierra Nevada frontal fault in southern California. The combination of stratigraphic and structural data from the Ricardo Group with chronologic and rotational histories derived from magnetos...

Is the transport of heat northward by the Gulf Stream and North Atlantic Drift, and its subsequent release into the midlatitude westerlies, the reason why Europe’s winters are so much milder than those of eastern North America and other places at the same latitude? Here, it is shown that the principal cause of this temperature difference is advection by the mean winds. South-westerlies bring wa...

Ectoparasites were sampled from small mammals collected in West Java, West Sumatra, North Sulawesi, and East Kalimantan, Indonesia, in 2007-2008 and were screened for evidence of infection from bacteria in the Rickettsaceae family. During eight trap nights at eight sites, 208 fleas were collected from 96 of 507 small mammals trapped from four orders (379 Rodentia; 123 Soricomorpha; two Carnivor...

STOCK DEFINITION AND GEOGRAPHIC RANGE Minke whales have a cosmopolitan distribution in polar, temperate and tropical waters. In the North Atlantic there are four recognized populations — Canadian east coast, west Greenland, central North Atlantic, and northeastern North Atlantic (Donovan 1991). These four population divisions were defined by examining segregation by sex and length, catch distri...

The Thirteen Towers of Chankillo run north to south along a low ridge within a fourth-century B.C.E. ceremonial complex in north coastal Peru. From evident observing points within the adjacent buildings to the west and east, they formed an artificial toothed horizon that spanned-almost exactly-the annual rising and setting arcs of the Sun. The Chankillo towers thus provide evidence of early sol...

Background: Ninety-five percent of low birth weight infants are born in developing countries. This study was aimed to assess the predictors of low birth in East Azerbaijan, North-west province of Iran. Materials and Methods: The study was conducted through a hospital based case–control design involving 49 women delivering low birth weight infants and 98 delivering normal weight infants. The dat...

The distribution of Gazella bennetti in Iran is reviewed. The species is commonly said to be confined to the southeastern part of the country, but is actually widespread over suitable areas, east of the Zagros Range and south of the Alborz. In the north and west of this range, there is a hitherto undescribed subspecies, which is named and diagnosed for the first time in this paper; its similari...
