Understanding the behavioral adaptations and subsistence strategies of Middle Paleolithic humans is critical in the debate over the evolution and manifestations of modern human behavior. The study of faunal remains plays a central role in this context. Until now, the majority of Levantine archaeofaunal evidence was derived from late Middle Paleolithic sites. The discovery of faunal remains from...
In 2009, Mycobacterium bovis infection was detected in a herd of 60 elk (Cervus elaphus) and 50 fallow deer (Dama dama) in Nebraska, USA. Upon depopulation of the herd, the prevalence of bovine tuberculosis (TB) was estimated at ∼71-75%, based upon histopathology and culture results. Particularly with elk, gross lesions were often severe and extensive. One year ago, the majority of the elk had ...
Low stature tropical forests, such as found on the Yucatán Peninsula, Mexico, are globally a threatened ecosystem, largely due to human habitation and development of agricultural activities. The virtual abandonment of sisal production surrounding Mérida has facilitated the regeneration of large areas of secondary forest. These forests provide multiple services, including carbon sequestration an...
Liver fluke Fascioloides magna is a typical parasite of American cervids. The reason for F. magna to appear in Poland territory was bringing the American wapiti deer to those forests around 1850. Along with these deer the aforementioned fluke was also introduced. The aim of this study was to present the case of finding of this species in cervids in Bory Zielonogórskie. Samples of deer feces wer...
Changes in population levels of Meloidogyne hapla, M. incognita, Pratylenchus coffeae, and P. penetrans were studied in 12 strawberry fields in the Dahu region of Taiwan. Ten potential rotation crops and two cultural practices were evaluated for their effect on nematode populations and influence on strawberry yield. Rotation with rice or taro and the cultural practice of flooding and bare fallo...
Blowing dust from excessively tilled fallow fields is a major soil loss and air quality concern in the low precipitation (<12 inches annually) wheat production region of the Inland Pacific Northwest (PNW). A 2-year, tillage-based winter wheatsummer fallow (WW-SF) rotation is practiced on more than 90% of rainfed cropland in the region. Earlier research proved that the undercutter method for non...
In a survey of game animals and small mammals, the sera of 185 animals were examined for the presence of immunoglobulin G antibodies to the spirochete Borrelia burgdorferi sensu lato, which causes Lyme borreliosis. These animals comprised 59 fallow deer (Dama dama), 56 mouflons (Ovis musimon) and 70 small mammals of six different species. The sera of the fallow deer and the mouflons were examin...
A survey of abomasal parasites in cervids from Central Spain was conducted at 3 sites, Quintos de Mora (Toledo), Maluéñez de Arriba (Cáceres), and La Herguijuela (Cáceres). Commonly occurring helminths belonged to 3 polymorphic species of the Ostertagiinae: Spiculopteragia asymmetricalS. quadrispiculata, Ostertagia leptospicularis/O. kolchida, and O. drozdzi/O. ryjikovi. Trichostrongylus axei w...
We present evidence to show that DAYCENT can reliably simulate soil C levels, crop yields, and annual trace gas fluxes for various soils. DAYCENT was applied to compare the net greenhouse gas fluxes for soils under different land uses. To calculate net greenhouse gas flux we accounted for changes in soil organic C, the C equivalents of N2O emissions and CH4 uptake, and the CO2 costs of N fertil...
Soil ecosystem perturbation due to agronomic practices can negatively impact soil productivity by altering the diversity and function of health determinants. Currently, influence rice cultivation off-season periods on dynamics determinants is unclear. Therefore, enzyme activities (EAs) bacterial community compositions in rice-cultivated fields at postharvest (PH) after a 5-month period (5mR), f...
