In three experiments investigating variables affecting responses of male Mongolian gerbils to conspecific young, we compared the behavior directed towards pups of natural fathers, virgin foster fathers, and sexually experienced foster fathers (Experiment 1); males either previously exposed or not exposed to pregnant females (Experiment 2); and males provided or not provided with extra opportuni...

Cultivation in semiarid grasslands induces large changes in soil organic matter (SOM) stock. To better predict the effects of cultivation on SOM pools, there is a need to identify the soil fractions that are affected and the extent to which they are affected. Using four cultivation chronosequences in Inner Mongolian grasslands of northern China, we investigated the changes in soil organic carbo...

Diethylcarbamazine (DEC) was effective in reducing microfilarial densities of Brugia pahangi in Mongolian jirds (Meriones unguiculatus) when it was administered intraperitoneally at the daily dosage of 300 mg/kg of body weight either for 5 consecutive days or every 3 days for 43 days with the total of 15 doses. The latter treatment scheme seemed to be more effective than the former, suggesting ...

The purpose of this study was to investigate whether sporulated Neospora caninum oocysts, which had been stored for 46 mo in a 2% sulfuric acid solution at 4 degrees C, remain morphologically viable and infective to gerbils (Meriones unguiculatus). Six gerbils were orally inoculated with doses of 400 or 1,200 oocysts. Two mo after inoculation, the animals did not show any clinical signs, had no...

The genus Liuella Wang et Bai, 1992 is transferred from Trombiculidae to Apoloniinae and a new species Liuella monosetosa sp. n. described from specimens taken in Morocco from the hosts Gerbillus sp. and Meriones libycus Lichtenstein. A new species of Straelensia Vercammen-Grandjean et Kolebinova, 1968, Straelensia variocula sp. n. is described from specimens taken in Morocco and Burkina Faso f...

Six mite species of the family Myobiidae, Radfordia (Austromyobia)persica sp. n., Radfordia (Austromyobia) merioni Bochkov, Dubinina et Chirov, 1990, Radfordia (Radfordia) acomys Fain et Lukoschus, 1977, Radfordia (Radfordia) affinis (Poppe, 1896), Radfordia (Graphiurobia) dyromys Fain et Lukoschus, 1973, and Myobia (Myobia) murismusculi (Schrank, 1781) were found in Iran on the rodents Gerbill...

Objective- Acipenser persicus is one of the most important caviar producing fishes in the Caspian Sea and one of the endangered species of the sturgeon fishes. For breeding of sturgeons, large numbers of animals have to be captured and examined to obtain sufficient numbers of mature fishes that will spawn within a few months in captivity. Design- Original study Animals- A total of 66 adult Acip...

Habitat loss and habitat fragmentation caused by anthropogenic activities are the main factors that constrain long-distance movement of ungulates. Mongolian gazelles (Procapra gutturosa) and Asiatic wild asses (Equus hemionus) in Mongolia are facing habitat fragmentation and loss. To better understand how their movements respond to potential anthropogenic and natural barriers, we tracked 24 Mon...
