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...

The phenomenon of syntenic genetic conservation of chromosomes enables application of molecular probes obtained from one species of animals to detect homologous DNA segments in another species. The aim of this study was identification of sex chromosomes in fallow deer (Dama dama), using in interspecies hybridizations in situ (Zoo-FISH technique) the bovine heterosomes painting probes. The resul...

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...

Sustainable management practices are needed to enhance soil productivity in degraded dryland soils in the northern Great Plains. We examined the effects of two tillage practices [conventional till (CT) and no-till (NT)], five crop rotations [continuous spring wheat (Triticum aestivum L.) (CW), spring wheat-fallow (W-F), spring wheat-lentil (Lens culinaris Medic.) (W-L), spring wheat-spring whea...
