Associations with topographic units or soil types that vary in water availability are widespread in plant communities and are one of the main structuring aspects for local species distribution patterns, yet the underlying mechanisms are poorly understood. We hypothesized that differential seedling performance across habitats, particularly during the dry season, leads to habitat associations in ...

background: fasciolosis is a well known parasitic disease of animals with public health importance. in rasht and bandar-an­zali, in gilan province, where experienced two large human fasciolosis outbreaks, no update information is available on ani­mal fasciolosis. paucity of information on animal fasciolosis in these regions and its possible impacts on human fasciolo­sis called us for carrying o...

This paper describes the development and validation of an inhibition ELISA based on gamma-irradiated tissue culture-derived antigen for the detection of antibody to Rift Valley fever virus (RVFV) in humans, domestic and wild ruminants. Validation data sets derived from field-collected sera in Africa (humans=1367, cattle=649, goats=806, sheep=493, buffalo=258, camels=156) were categorized accord...

Recent studies revealed that from various ecological factors influencing nectar yield and quality of a plant, soil properties can be as important microclimatic features. To date, few have investigated the relationship characters to traits bee pollinated plants growing in natural associations. Our study intended reveal which had most powerful impact on variables wild garlic (Allium ursinum L.). ...

Patterns of habitat use by fish assemblages in two chalk streams in southern England were examined to identify species preferences with respect to major habitat gradients. Both study sites, although differing in some physical habitat characteristics, mainly channel width, water temperature and instream cover, could be arranged similarly along a continuum extending from erosional to depositional...

The material comes from the Late Iron Age settlement of Dobrovăț-La Livadă in Iași County and represents food waste presenting butchering, burning, disarticulation marks. Considering total number specifically identified mammals, 90.36% them belong to domestic mammals rest 9.64% belongs only wild – Sus scrofa Cervus elaphus. Estimating slaughter ages provided little data, both due high degree bo...
