epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...

In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...

background: with increasing use of antibiotics, the number and type of microbial resistance to antibiotics have been raised and at result the need for synthesis of new antimicrobials or acquire new sources of antimicrobial is indisputable. in this study the antimicrobial effects of the flowering aerial parts of glaucium vitellinum and gaillonia aucheri were investigated. m aterials and methods:...
