Climate change affects means, variances and the intrinsic predictability of climate. However, experimental tests how changes in climatic plant traits, allocation strategies selective regime acting on them are scarce, as well evidence for importance root functional traits to cope with uncertainty. Here, we experimentally manipulated daily inter-seasonal precipitation-predictabilities tested thei...

The effects of condensed tannins (CT) extracted from seven forages on the motility of the economically important nematode, Trichostrongylus colubriformis (Giles, 1892), were evaluated by using a larval migration inhibition (LMI) assay. The assay involved incubation of third stage (L3) exsheathed T. colubriformis larvae with CT extracted from Lotus pedunculatus, Lotus corniculatus, sulla (Hedysa...

Habitat fragmentation affects the biodiversity and function of aboveground organisms in natural ecosystems but has not been studied for effects on belowground species. In this paper, we consider the diversity of the rhizobia associated with the indigenous legume Dalea purpurea in 3 residual prairie areas in Minnesota and Iowa. Using Dalea purpurea as a trap host, 218 rhizobia were recovered fro...

Background: Sainfoin (Onobrychis viciifolia) is a forage crop that yields high in arid and calcareous soils cultivated large areas. There aren’t many genetic diversity studies on the varieties of cultured sainfoin. This study was conducted to determine degree relationship between 23 landraces one registered variety. Methods: To take samples from populations, seeds were sown field 2014. Samples ...

In order to evaluate resistance of sainfoin (Onobrychis viciifolia) powdery mildew, seeds 19 accessions were collected from different parts Iran and sown at 4 locations, i.e. Kheirabad, Khoramabad, Semirom Tabriz, in 2014. Accessions evaluated for mildew severity index (DSI), forage dry matter yield (DM), digestibility (DMD) crude protein (CP) water soluble carbohydrate (WSC) concentrations ove...
