آزمایشی به منظور بررسی تأثیر تنش آب بر میزان ماده خشک و رنگیزههای فتوسنتزی در دو گونه از گیاه اسپرس (Onobrychis radiata & Onobrychis viciifolia) با استفاده از آزمایشهای فاکتوریل در قالب طرح کاملا تصادفی با چهار تکرار انجام گردید. گیاهان تحت مطالعه در محیط گلخانه با دمای حداکثر 38 درجه سانتیگراد و دمای حداقل 14 درجه سانتیگراد کشت شدند. چهل روز پس از کاشت، هر دو گونه تحت تنش آبی 50 و 75 درصدظرفی...
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...
Herein we describe the nests (including construction, closure, orientation, and depth of cells) of the bee Osmia (Ozbekosmia) avosetta Warncke found nesting near Antalya, Turkey, and Sepidan, Iran. Cells are unusual in that they are lined by two layers of colorful flower petals that sandwich a thin middle layer of mud. Analyses of pollen taken from scopal hairs of specimens from the Turkish sit...
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...
Anthelmintic bioactivity against gastrointestinal nematodes has been associated with leguminous forages supporting the hypothesis of a role of condensed tannins. However, the possibility that other compounds might also been involved has received less consideration. Using bio-guided fractionation, the current study aimed at characterizing the biochemical nature of the active compounds present in...
